Цель: сравнительный анализ госпитальных и отдаленных результатов открытой симультанной стратегии коронарного шунтирования + каротидной эндартерэктомии (КШ+КЭЭ) и гибридной стратегии чрескожного коронарного вмешательства + каротидной эндартерэктомии (ЧКВ+КЭЭ). Материалы и методы: В данное когортное, сравнительное, ретроспективное, открытое исследование включено 180 пациентов с сочетанным поражением коронарных и внутренних сонных артерий, направлявшихся на симультанное вмешательство или гибридную операцию в период с января 2011г по декабрь 2015г. и имевших сопоставимое поражение коронарного русла. Все исследуемые пациенты были разделены на две группы: группа 1 – КШ+КЭЭ (n=116) и группа 2 − ЧКВ+КЭЭ (n=64). В группе 1 средний период наблюдения составил 50±17 мес, в группе 2 – 53±17 мес. Комбинированная конечная точка включала в себя совокупность таких кардиоваскулярных событий, как: смерть + ИМ + ОНМК/ТИА. При критическом уровне значимости p<0,05 различия считались статистически достоверными. Результаты: в госпитальном периоде значимых различий по частоте осложнений получено не было. В группе 1 выявлено 2 летальных исхода (1,7%), 1 инфаркт миокарда (0,9%), 5 ишемических инсультов (4,3%). В группе 2 среди осложнений получено 3 кровотечения, потребовавших ревизии раны (4,7%) относительно 9 кровотечений группы КШ+КЭЭ, закончившихся ремедиастинотомией (7,8%), р=0,63. В отдаленном периоде наблюдения значимых различий по частоте неблагоприятных исходов получено не было, однако отмечено возрастание частоты комбинированной конечной точки в группе ЧКВ+КЭЭ против КШ+КЭЭ (15/64 (23,4%) vs 17/116 (14,9%), р = 0,2) за счет рестеноза/тромбоза стента, спровоцировавшего инфаркт миокарда и повторную незапланированную реваскуляризацию миокарда. Заключение: исследование не показало значимых различий результатов открытой и гибридной реваскуляризации миокарда и головного мозга. Однако выявлена тенденция в нарастании числа неблагоприятных кардиоваскулярных событий после ЧКВ+КЭЭ в отдаленном периоде относительно КШ+КЭЭ в виду возрастания числа тромбозов/рестенозов стента. Данная особенность подчеркивает преимущества более агрессивных методов реваскуляризации над интервенционными. Objective: A comparative analysis of the hospital and long-term results of the open strategy - simultaneous coronary artery bypass grafting + carotid endarterectomy (CABG+CEE) and the hybrid strategy - percutaneous coronary intervention + carotid endarterectomy (PCI+CEE). Materials and methods: This cohort, comparative, retrospective, open-label study included 180 patients with a comparable lesion of the coronary channel and combined lesions of the coronary and internal carotid arteries going for simultaneous intervention or a hybrid operation from January 2011 to December 2015. All studied patients were divided into two groups: Group 1 - CABG+CEE (n=116); Group 2 - PCI+CEE (n=64). In group 1, the average follow-up period was 50±17 months; in group 2 - 53±17 months. Results: in the in-hospital period, no significant differences in the frequency of complications were obtained. 2 deaths (1.7%), 1 myocardial infarction (0.9%) and 5 ischemic strokes (4.3%) were detected in group 1. There were 3 bleedings cases requiring wound revision (4.7%) in the PCI + CEE group versus 9 in the CABG + CEE group requiring remediastinotomy (7.8%), p=0.63. In the long-term follow-up no significant differences in the frequency of adverse outcomes were obtained, however, an increase in the combined endpoint frequency in the PCI+CEE group as compared to CABG+CEE group was noted (15/64 (23,4%) vs 17/116 (14,9%), р=0,2, due to the stent restenosis/thrombosis which provoked myocardial infarction and repeated unplanned myocardial revascularization. Conclusion: the study showed no significant differences when performing open or hybrid myocardium and brain revascularization. However there is a tendency to increase the number of adverse cardiovascular events in the long-term period after PCI+CEE as compared to CABG+CEE mostly due to stent thromboses/restenoses. This feature emphasizes the advantages of more aggressive methods of revascularization over interventional.

Eversion Endarterectomy

Aim. Analysis of long-term results of eversion carotid endarterectomy in patients with atherosclerotic carotid stenosis.Methods. 272 eversion carotid endarterectomy surgeries was performed from June 2008 to December 2014 in the department of cardiac surgery. Long-term results were studied in 198 (73%) patients, with follow-up term ranging from 6 to 48 months. The method of operation serves as a criterion separating Patients were allocated into two groups by the surgery method: in the first group, eversion endarterectomy was performed by Kieny, in the second - by DeBakey.Results. Reconstructed ipsilateral internal carotid artery was passable during the follow-up period in 100% of cases, as confirmed by ultrasonography. In the late period, the mortality in the first group was 2.3% (myocardial infarction and cancer), compared to 1.5% in the second group (myocardial infarction). Acute ischemic stroke occurred in 0.8% of the first group patients and in 1.5% of the second group patients. Restenosis of 50 to 69% were discovered in 3.7% of cases in first group and in 3% in the second group. Restenosis ≥70% were found in 1.5% in both groups of patients.Conclusion. The obtained data confirm that both methods of eversion carotid endarterectomy are safe and reliable in treatment of carotid arteries atherosclerosis and, thus, preventing stroke.

Aim. This study provides an analysis of the results of eversion carotid endarterectomy (CEE) with transposition of the internal carotid artery (ICA) over the hypoglossal nerve, according to A.N. Kazantsev. Materials and Methods. The given prospective open study covering the period from January 2017 to May 2020 involved 311 patients who underwent eversion CEE with transposition of ICA over the hypoglossal nerve, according to A.N. Kazantsev. Transposition was performed in the following way: after standard isolation of the carotid arteries, their compression, arteriosection, and removal of atherosclerotic plaque, ICA was extracted in the area above the hypoglossal nerve and was implanted to the same position. The condition of the patient was controlled on repeated visits to the clinic every six months. Hemodynamics in the reconstruction zone were studied using multispiral computed tomography with angiography of carotid bifurcation with 0.6 mm steps and processing the obtained results in Sim Vascular and Open Foam programs in DICON format. The follow-up period was 18.37.1 months. In case of development of restenosis, reCEE was performed with patch plasty of the reconstruction zone. For histologic examination, the restenosis area was stained by the van Gieson method. Results. In the hospital follow-up period, one case of myocardial infarction was noted that developed due to the stents thrombosis in the anterior descending artery deployed two years before. When studying the hemodynamic properties of carotid bifurcation in the postoperative period using computer modeling, in all cases, no changes or obstacles to blood flow were formed in the ICA in the area above the hypoglossal nerve. In the long-term follow-up period, two cases of lethal outcome were recorded connected with the onset of an oncological disease. In one case, due to recurrence of the pulmonary artery thromboembolism. In two cases, the cause of myocardial infarction was thrombosis/occlusion of venous anastomoses (in one patient to the circumflex artery, in the other to the right coronary artery). In four cases, repeated acute cerebrovascular accidents developed due to restenosis after CEE. In cases of significant restenosis (n=8), reCEE was performed with plasty of the reconstruction zone with a patch. The average restenosis period was 8.23.6 months. No cardiovascular complications and cases of hypoglossal nerve traumatization were identified. Intraoperatively, it was confirmed that restenosis was formed in the bifurcation zone, in front of the perimeter of the primary arteriosection. According to the results of histological examination, the main cause of all restenoses was hyperplasia of the neointima. Conclusion. The eversion CEE with the transposition of the ICA, according to A.N.Kazantsev, creates conditions for additional maneuvers in case of restenosis and implementation of reCEE. The ICAs placement over the hypoglossal nerve during primary CEE allows more confident isolation of carotid artery bifurcation from scar tissues with a zero risk of damage to the hypoglossal nerve. Such a course of the operation makes it possible to apply a clamp on the ICA and perform arteriotomy in any location without the threat of injury to the nerve structures.

Purpose. To present the feasibility, safety, and efficacy of carotid endarterectomy in patients with type II internal carotid artery occlusions, including the long-term outcomes. Methods. From March 2008 to August 2015, 74 consecutive patients (48 men with a mean age of 65.1 ± 8.06 years) underwent carotid endarterectomy because of internal carotid artery (ICA) segmental occlusions. These were verified with preoperative carotid duplex scans (CDS) and CT angiography (CTA). Also, brain CT scanning was performed in all these patients. The indication for treatment was made jointly by a vascular surgeon, neurologist, and an interventional radiologist in a multidisciplinary team (MDT) context. After successful treatment, all the patients were followed-up at 1, 3, 6, and 12 months, then every 6 months thereafter. Results. The most common symptom at presentation was transient ischaemic attack (TIA) in 49 patients (66.2%), followed by stroke in the past six months in the 17 remaining patients (23%). Revascularisation of the ICA with endarterectomy techniques was performed successfully in all the patients with an average clamp time of 11.9 min. All the procedures were performed under general anaesthesia in combination with a superficial cervical block. The early complication rate was 8.1% and included two cardiac events (2.7%) (one rhythm disorder and one acute coronary syndrome), three TIAs (4.1%), and one intracerebral hemorrhage (1.3%). Only one patient with the intracerebral hemorrhage died 5 days after surgery giving a postoperative mortality of 1.3% for this series. During the follow-up period (mean 50.4 ± 31.3 months), the primary patency rates at 1, 3, 5, and 7 years were 98.4%, 94.9%, 92.9%, and 82.9%, respectively. Likewise, the survival rates were 98.7%, 96.8%, 89%, and 77.6%, respectively. Ultrasound Doppler controls during follow-up detected 8 ICA restenoses; however, only 3 of these patients required further endovascular treatment. Conclusions. Carotid endarterectomy of internal carotid artery (ICA) segmental occlusion is a safe and effective procedure associated with acceptable risk and good long-term results. Therefore, the current guidelines which do not recommend carotid endarterectomy in this patient group should be reassessed, with the requirement for ongoing large-scale randomized controlled trials to compare CEA with best medical therapy in this patient cohort.

Background: Although skin adhesives have been used for decades to treat skin lacerations, uncertainty remains about long-term results, and complications.Methods: In this prospective, controlled, single-blinded, observational cohort study, outcomes were assessed by five plastic surgeons with standardized photographs at 6–12 months using a modified Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS); additionally, the POSAS was performed by the patients/caregivers and the physician; pain, requirement of anesthesia, treatment time, costs, complications, and quality of live (QoL) were assessed.Results: A total of 367 patients were enrolled; 230 were included in the main analysis; 96 wounds were closed using tissue adhesives (group 1); 134 were sutured (group 2). Assessment by the independent observers revealed an improved mean modified overall POSAS score in group 1 in comparison with group 2 [2.1, 95% CI [1.97–2.25] vs. 2.5, 95% CI [2.39–2.63]; p &lt; 0.001, d = 0.58] and mean VSS score [1.2, 95% CI [0.981–1.34] vs. 1.6, 95% CI [1.49–1.79], p &lt; 0.001, d = 0.53]. At the early follow-up, dehiscence rate was 12.5% in group 1 and 3.7% in group 2 (p &lt; 0.001); later on, one dehiscence remained per group. Mild impairment of QoL was found at the early follow-up in both groups, with no impairment remaining later on. Duration of treatment and treatment costs were lower in group 1.Conclusion: Both modalities of wound closure yield favorable esthetic results, and complications are rare. Adhesives are more cost-effective, and its application is less time-consuming; therefore, tissue adhesives offer considerable advantages when used appropriately.Trial Registration: Public trial registration was performed at www.ClinicalTrials.gov (Identifier: NCT03080467).

Aim. Analysis of hospital and long-term results of carotid endarterectomy (CEA) in different periods of acute cerebrovascular event (ACVE). Materials and Methods. The given study was retrospective and was conducted using the method of patients sampling. In the period from 2010 to 2019, 1113 patients with ACVE in history who were later conducted CEA, were selected. Depending on the time interval between the last ACVE and CAE, all the patients were divided into 4 groups: the 1st group in the acutest period of ACVE (1-3 days) (n=24; 2.2%); the 2nd group in the acute period of ACVE (up to 28 days) (n=493; 44.3%); the 3rd group in the early rehabilitation period of ACVE (up to 6 months) (n=481; 43.2%); the 4th group in the late rehabilitation period of ACVE (up to 2 years) (n=115; 10.3%). The long-term period was 34.812.5 months. Results. In the hospitalization period of observation the following complications were found: lethal outcome ((group 1 0%; group 2 0.4% (n=2); group 3 0.2% (n=1); group 4 0%; р=0.16)); myocardial infarction ((group 1 0%; group 2 0.4% (n=2); group 3 0%; group 4 0.9% (n=1); р=0.35)); ACVE/transient ischemic attack (TIA), ((group 1 4.2% (n=1); group 2 0.4% (n=2); group 3 0.2% (n=1); group 4 0%; р1-2=0.01; р1-3=0.009; р1-4=0.01)). By the end of hospitalization period the composite endpoint consisting of lethal outcome + myocardial infarction + ACVE/TIA made in group 1 4.2% (n=1), in group 2 1.2% (n=6), in group 3 0.4% (n=2), in group 4 2.6% (n=3), р=0.08. Complications of the long-term follow-up period were: lethal outcome from all causes ((group 1 25% (n=6); group 2 5.5% (n=27); group 3 7.3% (n=35); group 4 14% (n=16); р1-2=0.002; р1-3=0.008; р2-4=0.012)); lethal outcome from cardiovascular causes ((group 1 4.2% (n=1); group 2 3.6% (n=18); group 3 4.8% (n=23); group 4 5.2% (n=6); р=0.79)), myocardial infarction ((group 1 12.5% (n=3); group 2 3.6% (n=18); group 3 5.4% (n=26); group 4 6.1% (n=7); р=0.15)), ACVE/TIA ((group 1 16.6% (n=4); group 2 6.3% (n=31); group 3 6% (n=29); group 4 11.3% (n=13); р=0.05)); composite endpoint including lethal outcome + myocardial infarction + ACVE/TIA ((group 1 54.2% (n=13); group 2 15.4% (n=76); group 3 18.7% (n=90); group 4 31.3% (n=36); р1-2=0.0001; р1-3=0.0001; р1-4=0.005; р2-4=0.0006; р3-4=0.012)). Conclusion. Application of CEA demonstrated effectiveness and safety in the acute and early rehabilitation period of ACVE.

The aim of this study was to analyse the inpatient and long-term results of hybrid surgery, incorporating percutaneous coronary intervention (PCI) and different types of carotid endarterectomy (CEA). Materials and methods. A prospective, open-label cohort comparison study was conducted in 20182020 and included 363 patients with atherosclerosis of both the internal carotid artery (ICA) and coronary artery, who underwent hybrid revascularization of the brain and myocardium. All patients were divided into four groups based on the revascularization strategy: group 1 (n = 107; 29.5%) PCI + eversion CEA; group 2 (n = 98; 27%) PCI + classic CEA with patch angioplasty; group 3 (n = 72; 19.8%) PCI + glomus-sparing CEA according to R.A. Vinogradov; and group 4 (n = 86; 23.7%) PCI + glomus-sparing CEA according to A.N. Kazantsev. The follow-up period was 20.8 8.0 months. The patient received a loading dose of clopidogrel (300 mg) before the PCI, and the procedure was then performed in an endovascular operating room. A radial artery catheter was inserted, and the patient received 10,000 IU of intravenous heparin before the procedure. After the PCI, the patient was taken to the vascular operating room, where they underwent the CEA. The patient received 5,000 IU of intravenous heparin before artery clamping. Glomus-sparing CEA according to A.N. Kazantsev was performed as follows: an arteriotomy was conducted along the internal edge of the external carotid artery (ECA), adjacent to the carotid sinus and 23 cm above the ostium, and extending to the common carotid artery (CCA) (also 23 cm below the ECA ostium), depending on the size of the atherosclerotic plaque. The ICA was transected in the area bound by the ECA and CCA walls. Eversion CEA of the ICA was performed, followed by open CEA of the ECA and CCA. The ICA was implanted in its previous position in the preserved area. Results. No mortality was recorded during the inpatient follow-up period. All cases of myocardial infarction occurred after eversion and classic CEA: 3 in group 1 (2.8%) and 1 in group 2 (1.02%); р = 0.2. No ischaemic stroke was recorded only in patients who underwent CAE according to A.N. Kazantsev (р = 0.66); however, ischaemic stroke occurred in two patients in group 1 (1.8%), in two patients in group 2 (2.04%) and in one patient in group 3 (1.38%). The highest number of cardiovascular events occurred in group 1, due to carotid glomus injury, which led to poorly controlled hypertension during the inpatient stay. This tendency influenced the composite endpoints (death + myocardial infarction + ischaemic stroke), which were highest in group 1 (5 or 4.6%) compared to 3 (3.06%), 1 (1.38%) and 0 in groups 24, respectively (р = 0.18). The groups were comparable in the frequency of long-term complications. However, the incidence of ICA restenosis was lowest and no ECA thrombosis/occlusion was observed after glomus-sparing CEA according to R.A. Vinogradov and A.N. Kazantsev. Conclusion. A hybrid PCI + CEA for brain revascularization should be glomus-sparing. CEA according to A.N. Kazantsev was characterized by lack of procedural arteriotomy complications. This procedure enables blood pressure monitoring in the postoperative period, thus minimizing the risk of cardiovascular complications.

Background: Aortic coarctation is among the most common cardiovascular congenital abnormalities requiring repair after birth. Besides mortality, morbidity remains an important aspect. Accordingly, we reviewed our 20-year experience of aortic coarctation repair by thoracotomy, with emphasis on both short- and long-term outcomes. Methods: From 1995 through 2014, 214 patients underwent coarctation repair via left thoracotomy. Associated arch lesions were distal arch hypoplasia (n = 117) or type A interrupted aortic arch (n = 6). Eighty-four patients had isolated coarctation (group 1), 66 associated ventricular septal defect (group 2), and 64 associated complex cardiac lesions (group 3). Median follow-up was 8.4 years. Results: There was one (0.5%) procedure-related death. Nine (4.2%) patients died during index admission. In-hospital mortality was 0.7% in group 1 and 2 and 12.5% in group 3 ( P < .001). No patient had paraplegia. Actuarial five-year survival was 97.5% in group 1, 94% group 2 and 66% in group 3. Recurrent coarctation developed in 29 patients, all but four (1.8%) successfully treated by balloon dilatation. Freedom from reintervention (dilatation or surgery) at five years was 86%. At hospital discharge, 28 (13.5%) patients were hypertensive. At follow-up, hypertension was present in 11 (5.3%) patients. Conclusions: Long-term results of aortic coarctation repair by thoracotomy are excellent, with percutaneous angioplasty being the procedure of choice for recurrences. Patient prognosis is dependent on associated cardiac malformations. In this study, the prevalence of late arterial hypertension was lower than previously reported.

Purpose of the study. Comparison of hospital and long-term results of autoarterial reconstruction of carotid artery bifurcation and the formation of a new bifurcation with an extended atherosclerotic lesion of the internal carotid artery (ICA). Materials and methods. In the period from January 2018 to May 2020, this cohort, comparative, prospective, open-label study included 279 patients with an extended atherosclerotic lesion of the ICA operated on in the Alexandr Hospital. Depending on the implemented strategy of surgical correction, all patients were divided into two groups: group 1 (n=132) — autoarterial reconstruction of bifurcation of the carotid arteries; Group 2 (n=147) — the formation of a new bifurcation. Complications were recorded in the hospital and long-term postoperative periods. The total follow-up period was 16.4±9.3 months. The endpoints of the study were such adverse cardiovascular events as death, myocardial infarction (MI), stroke, thrombosis / restenosis of the anastomosis zone, combined endpoint (death from stroke / IM + IM + stroke). Results. The ICA clamping time in group 1 was 32.6±3.3 minutes, in group 2 – 31.7±3.5 minutes, which did not receive statistically significant differences (р=0.81). In the hospital postoperative period, adverse cardiovascular events were not recorded. In the long-term follow-up, the groups were comparable in the frequency of all complications. Identified lethal outcomes developed as a result of the formation of MI in patients with multiple lesions of the coronary arteries and a history of myocardial revascularization. The likely cause was shunt / stent thrombosis with subsequent coronary insufficiency and an increase in ischemic heart damage. The causes of stroke, recorded in each group in isolated cases, were the presence of atrial fibrillation. Patients did not comply with the recommended regimen of anticoagulant therapy, which provoked the development of cerebral catastrophe. In turn, the identified restenoses of the reconstruction zone were asymptomatic and were also observed in isolated cases in each group in the period 12 months after CEE. Conclusion. Autoarterial reconstruction of carotid bifurcation and the formation of a new bifurcation are comparable in safety and effectiveness methods of surgical treatment of an extended atherosclerotic lesion of the ICA. Operation techniques differ in the choice of an artery that is cut off from bifurcation — the external carotid artery or ICA. Further, the reconstruction progress is absolutely identical. Hospital and long-term follow-up results showed minimal indicators of the development of cardiovascular and hemodynamic changes due to the type of operation. Thus, both reconstruction techniques can be the operation of choice for an extended ICA lesion.

Aim. To analyze the immediate and long-term outcomes of eversion and conventional carotid endarterectomy (CE) with patch angioplasty.Material and methods. For the period from February 1, 2006 to September 1, 2021, the present retrospective multicenter open comparative study included 25106 patients who underwent CE. Depending on the technique of operation, the following groups were formed: group 1 (n=18362) — eversion CE; group 2 (n=6744) — conventional CE with patch angioplasty. The long-term follow-up period was 124,7±53,8 months.Results. In the hospital postoperative period, the groups were comparable in incidence of all complications: lethal outcome (group 1: 0,19%, n=36; group 2: 0,17%, n=12; p=0,89; odds ratio (OR) =1,1; 95% confidence interval (CI) =0,57- 2,11); myocardial infarction (MI) (group 1: 0,15%, n=28; group 2: 0,13%, n=9; p=0,87; OR=1,14; 95% CI=0,53-2,42); stroke (group 1: 0,33%, n=62; group 2: 0,4%, n=27; p=0,53; OR=0,84; 95% CI=0,53-1,32); bleeding with hematoma formation (group 1: 0,39%, n=73; group 2: 0,41%, n=28; p=0,93; OR=0,95; 95% CI=0,61-1,48); internal carotid artery (ICA) thrombosis (group 1: 0,05%, n=11; group 2: 0,07%, n=5, p=0,9; OR=0,8; 95% CI=0,28-2,32). In the long-term follow-up, the groups were comparable only in MI incidence: group 1: 0,56%, n=103; group 2: 0,66%, n=45; p=0,37; OR=0,84; 95% CI=0,59-1,19. All other complications were more frequent after conventional CE with patch angioplasty: all-cause death (group 1: 2,7%, n=492; group 2: 9,1%, n=616; p<0,0001; OR=0,27; 95% CI=0,24-0,3); lethal ischemic stroke (group 1: 1,0%, n=180; group 2: 5,5%, n=371; p<0,0001; OR=0,17; 95% CI=0,14-0,21); non-lethal ischemic stroke (group 1: 0,62%, n=114; group 2: 7,0%, n=472; p<0,0001; OR=0,08; 95% CI=0,06-0,1); ICA restenosis >60%, requiring re-revascularization (group 1: 1,6%, n=296; group 2: 12,6%, n=851; p<0,0001; OR=0,11; 95% CI=0,09-0,12). Thus, the composite endpoint (lethal ischemic stroke + non-lethal ischemic stroke + MI) after conventional CE with patch angioplasty was more than 6 times higher than this parameter of eversion CE: group 1: 2,2%, n=397; group 2: 13,2%, n=888; p<0,0001; OR=0,14; 95% CI=0,12-1,16.Conclusion. Conventional CE with patch angioplasty is not prefer for cerebral revascularization in the presence of hemodynamically significant ICA stenosis due to the high prevalence of deaths, stroke, and ICA restenosis in the long-term follow-up.

Group 1

The study included 1172patients (410 men and 762 women) at the mean age of 60.3±10.4years with grade I-II (stage I-II) arterial hypertension (AH) admitted to the clinic of Institute of Experimental Medicine. The patients were divided into 2 groups based on the results of clinical and laboratory diagnostics. Group 1 (n=525) included patients with AH and hepatobiliary system (HBS) diseases, group 2 (n=647) patients with AH without HBS diseases. The patients group 1 had a thicker intima-media complex of carotid arteries, higher peak systolic bloodflow rate in the internal and vertebral carotid arteries, more pronounced coiling of internal carotid arteries than patients of group 2. Patients with AH and HBS diseases exhibited correlation between blood flow rate in external carotid arteries and atherogenicity coefficient. Duplex scanning of neck vessels of in patients with AH without HBS diseases revealed peculiar changes of the intima-media thickness and hemodynamically significant changes of the blood flow in the internal carotid arteries that may be of prognostic value in this nosological syntropy and require the personified approach to diagnostics, treatment, and prevention of these conditions.
