Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Moebius syndrome (MS) is a rare disease, with paralysis of the VI and VII cranial nerves, frequently associated with clubfoot (CF). The aim of this study was to evaluate surgical treatment of CF in MS, providing its peculiarities. Between 1990 and 2019, we collected data of 11 MS patients with unilateral (n = 5) or bilateral (n = 6) CF, for a total of 17 feet (9R,8L). Six patients (3M,3F) for a total of 10 feet (6R,4L) were treated elsewhere, performing first surgery at an average age of nine months, and in our hospital for relapse surgery at an average age of 4.5 years (Group 1). Five patients (3M, 2F), for a total of seven feet (3R,4L), were primarily treated in our hospital with a peritalar release according to McKay at an average age of 9.4 months (Group 2). Diméglio score was used to assess CF severity. Three questionnaires were submitted for evaluation of subjective and functional results: American Orthopedics Foot and Ankle Society for Hindfoot (AOFAS), Foot and Ankle Outcome Score (FAOS), and Foot and Ankle Ability Measure (FAAM). Average AOFAS/FAOS/FAMM scores were 82.8, 84.8, and 82.3 for Group 1, and 93.2, 94.7, and 95.1 for Group 2 at an average follow-up of 16.9 and 13.3 years, respectively. The average Diméglio score improved from 15.5 to 4.8 in the long-term follow-up in Group 1 and from 14.6 to 3.8 in Group 2. The comparison between the groups showed better results for AOFAS, FAOS, and FAAM scores for Group 2, particularly for pain, function, and foot alignment and for the post-surgical Diméglio score. CF in MS is more severe and presented a higher relapse rate (58.8%) than idiopathic CF. Peritalar release showed no relapse and better subjective and functional results in the long-term follow-up compared to other surgical techniques

Mitral regurgitation due to bileaflet prolapse and ischemic causes can be difficult to repair. Midterm experience of the Alfieri edge-to-edge repair as an alternative to valve replacement is reported. Twenty-six patients with severe mitral regurgitation underwent the Alfieri repair between January 1998 and December 2000 (group 1); 15 cases were due to bileaflet prolapse and 7 were of ischemic origin. During the same period, valve replacement was performed in 36 patients (group 2), 20 of whom had similar indications. Follow-up was complete to a mean of 15 months (range, 1–28 months). There was no early death in either group. During follow-up, there was no reoperation in group 1, while 2 patients in group 2 required reoperations due to prosthetic valve endocarditis. There were 4 major thromboembolic or bleeding events in group 2, and none in group 1. All patients in group 1 had trivial to mild mitral regurgitation on follow-up echocardiography. The mean mitral valve gradient was significantly higher in group 2 compared to group 1 (7.2 versus 3.2 mm Hg, p = 0.001). The edge-to-edge repair is associated with good early and midterm results. Long-term follow-up is required to evaluate the durability of this technique.

Objective: Multinodular goiter is a common surgical disease. There is no common consensus regarding the extent of thyroidectomy for multinodular goiter. This  study aims to present personal experience on treating patients with multinodular goiter and to compare complication rates and results of total and partial thyroidectomy for multinodular goiter. Material and Method: Three hundred fifty patients underwent thyroidectomy for multinodular goiter between May 2003 and October 2010. All patients were diagnosed as multinodular goiter and were referred to surgery by one endocrinologist. All operations were also performed by one surgeon using microsurgical techniques. Partial thyroidectomy (bilateral subtotal or unilateral total thyroidectomy and contralateral subtotal thyroidectomy) was performed in 65 patients (Group-1) and extracapsular total thyroidectomy was performed in 285 patients (Group-2). All patients are being followed followed from the day they were diagnosed until now by the same endocrinologist. Fisher exact test was used for statistical analysis. Results: In Group-1, one patient had transient vocal-cord palsy and but none had hypoparathyroidism. On the other hand, in Group-2, two patients had transient vocal-cord palsy, five had hypocalcemia (one was permanent), and one had a hematoma. Mortality and wound infection were absent in both groups. The histopathological studies showed that 40 incidental thyroid carcinomas occurred among Group-2 patients. During long-term follow-up, 13 patients had goiter recurrence (n = 65, 20%) in Group-1, whereas none had goiter recurrence in Group-2. Conclusion: There were no statistically significant differences in the complication rate between subtotal and total thyroidectomy groups (p>0.05). However, the recurrence rate was higher (statistically significant) after subtotal thyroidectomy than after total thyroidectomy (p<0.05). Total thyroidectomy eliminated future recurrence of the disease and is also curative in incidental thyroid carcinomas. In addition, it can be safely performed using microsurgical techniques.

This retrospective study analyzed the surgical and refractive outcomes of a XEN Gel Implant (Allergan, Abbvie Company, Irvine, CA, USA) in naïve patients versus those with previous glaucoma surgery. We evaluated the efficacy of XEN implantation in 86 glaucoma patients during a long-term follow-up period. Patients were divided into two groups: naïve patients (Group 1) and patients with previous glaucoma surgery (Group 2). Eyes that received a XEN Gel Stent placement from December 2014 to October 2019 were included. Intraocular pressure (IOP) change, corrected distance visual acuity (CDVA), change in glaucoma medications, frequency of slit lamp revision procedures, and frequency of secondary glaucoma surgeries were the primary outcomes. In Group 1, the mean IOP before surgery was decreased significantly from 25.00 ± 7.52 mmHg to 16.83 ± 5.12 mmHg by the end of the study. In Group 2, the mean IOP decreased significantly from 25.35 ± 7.81 mmHg to 17.54 ± 5.34 mmHg. The mean IOP decrease from baseline was 29% in Group 1 and 27% in Group 2 (p = 0.567). There were no significant differences between the groups in the IOP baseline level, the final level, or the change between preoperative and final levels. The qualified success rate for Group 2 was 68.7% versus 76.5% for Group 1 for the initial procedure and 15.4% vs. 20.2%, respectively, for complete success rate (p > 0.05). However, at the end of the follow-up, more patients achieved an IOP < 18 mmHg in Group 1 than in Group 2. Despite the need for more anti-glaucoma medications, repeat XEN Gel implantation appears to show promising results in patients with previously failed anti-glaucoma procedures, owing to its minimal invasiveness.

Objective: To investigate the changes in macular retinal layers and panretinal neuroretinal functions in the long-term follow-up of patients with primary open-angle glaucoma. Materials and Methods: Forty-one patients diagnosed with primary open-angle glaucoma were followed up for 12 months. According to their mean deviation (MD) values), the patients were put into two groups as Group 1 with early stage glaucoma (MD≥-6) and Group 2 with middle-advanced stage glaucoma (MD<-6). Optical coherence tomography (OCT) and multifocal electroretinography (mfERG) were performed at the baseline and at the sixth- and 12th-month evaluations. The OCT, retinal layer and mfERG findings were compared between the two groups. Results: There was no statistically significant difference between the groups in terms of gender and age In Group 2, the mean baseline macula Retina Nerve Fiber Layer, Ganglion Cell Layer and Inner Pleksiform Layer measurements were lower in each quadrant compared to Group 1. Concerning progression in OCT measurements, there was no significant difference between the two groups. However, it was noteworthy that in Group 2, there was a decrease especially in the first and second ring amplitudes of the P1 and N2 waves and prolongation of the implicit time. At the 12-month evaluation, there was prolongation of the implicit time of the N1 wave and a decrease in the P1 wave amplitude in Group 1. Conclusion: Retinal layers are affected in patients with intermediate and advanced stage glaucoma. In the follow-up of early stage glaucoma patients, mfERG measurements can show damage that may occur.

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.

Abstract BACKGROUND While recent data has demonstrated the utility of lumbar pedicle screws for the treatment of vertebral osteomyelitis, the data are limited for thoracic pedicle screws. OBJECTIVE To investigate the effectiveness of thoracic pedicle screws for the surgical treatment of vertebral osteomyelitis. METHODS A retrospective review of all operations performed by 2 spinal neurosurgeons from 1999 to 2012 yielded 30 cases of vertebral osteomyelitis that were treated with thoracic pedicle screws. Sixteen (53%) of which underwent combined anterior and posterior fusion and 14 patients (47%) underwent standalone posterior fusion. Postoperative records were analyzed for pertinent clinical, laboratory, and radiographic data. RESULTS Of the 30 patients, 21 were males (70%), 8 were females (27%), and 1 was transsexual (3%). The mean age was 47 yr (range 18-69). The most common organism cultured was Staphylococcus aureus in 12 cases (50%). The mean patient stay in the hospital was 12.4 d after surgery (range 5-38 d). The mean antibiotic duration after discharge was 8 wk (range 1-24 wk). Of the 25 patients with long-term follow-up (mean, 49 mo), 92% had improved back pain (6/25 marked improvement, 17/25 complete resolution), 83% had improved muscle weakness (8/18 marked improvement, 7/18 complete resolution), and 100% had improved urinary incontinence (3/8 marked improvement, 5/8 complete resolution). Two patients (7%) required additional surgical revision due to instrumentation failure or wound infection. CONCLUSION This study demonstrates the efficacy of utilizing thoracic pedicle screws as a primary intervention to treat vertebral osteomyelitis.

Objective: to analyze the in-hospital and long-term outcomes of classical carotid endarterectomy (CEE) in extended atherosclerotic lesions in comparison with the outcomes of this operation in local atherosclerotic plaque (AP). Materials and Methods. This study, which lasted from January 2010 to December 2020, included 148 patients with extended AP and hemodynamically significant internal carotid artery (ICA) stenosis. The term “extended” was understood as a hemodynamically significant lesion ≥ 5 cm long. These patients made up Group 1. Group 2 was formed over the same period of time from 632 patients with hemodynamically significant stenosis <5 cm long. In both cohorts, CEE with repair of the reconstruction zone with a diepoxide-treated xenopericardial patch was performed. Long-term follow-up was 71.4 ± 45.6 months. Results. The groups were comparable in terms of frequency of in-hospital complications: death (group 1: 0.67%, n = 1; group 2: 0.5%, n = 3; p = 0.74; OR = 1.42; 95% Cl 0.14-13.6), myocardial infarction (MI) (group 1: 0.67%, n = 1; group 2: 0.5%, n = 3; p = 0.74; OR = 1.42; 95% CI 0.14-13.6), ischemic stroke (group 1: 0%; group 2: 0.5%, n = 3; p = 0.91; OR = 0.6; 95% CI 0.03-11.8), combined endpoint (death + MI + stroke) (group 1: 1.35%, n = 2; group 2: 1.4%, n = 9; p = 0.74; OR = 0.94; 95% CI 0.2-4.43). The groups were also comparable in terms of frequency of long-term complications: death (group 1: 2.0%, n = 3; group 2: 2.05%, n = 13; p = 0.76; OR = 0.98; 95% CI 0.27-3.5), MI (group 1: 2.7%, n = 4; group 2: 2.4%, n = 15; p = 0.95; OR = 1.14; 95% CI 0.37-3.49), ischemic stroke (group 1: 5.4%, n = 8; group 2: 5.2%, n = 33; p = 0.9; OR = 1.03; 95% CI 0.46-2.29), ICA occlusion and restenosis (group 1: 12.8%, n = 19; group 2: 13.3%, n = 84; p = 0.99; OR = 0.96; 95% CI 0.56-1.63), combined endpoint (death + MI + stroke) (group 1: 10.1%, n = 15; group 2: 9.6%, n = 61; p = 0.98; OR = 1.05; 95% CI 0.58-1.91). Analysis of survival graphs revealed no significant intergroup differences for all types of complications (lethal outcome: p = 0.56; MI: p = 0.73; stroke/mini-stroke: p = 0.89; ICA restenosis/occlusion: p = 0.82; combined end point: p = 0.71). Their increase was uniform in both groups. However, more than half of all ICA restenoses and occlusions were visualized in the first 6 months after CEE. Conclusion. Implantation of a long patch (≥ 5 cm) is not characterized by increased incidence of restenosis and all adverse cardiovascular events during in-hospital and long-term follow-up.

Background Mortality from chronic heart failure (CHF) remains high and entails serious demographic losses worldwide. The most vulnerable group is patients after acute decompensated HF (ADHF) who have a high risk of unfavorable outcome.Aim To analyze risks of all-cause death (ACD), cardiovascular death (CVD), and death from recurrent ADHF in CHF patients during two years following ADHF in long-term follow-up with specialized medical care and in real-life clinical practice.Material and methods The study successively included 942 CHF patients after ADHF. 510 patients continued out-patient treatment in a specialized CHF treatment center (CHFTC) (group 1) and 432 patients refused of the management in the CHFTC and were managed in out-patient clinics at the place of patient’s residence (group 2). Causes of death were determined based on inpatient hospital records, postmortem reports, or outpatient medical records. Cases of ACD, CVD, death from ADHF, and a composite index (CVD and death from ADHF) were analyzed. Statistical analysis was performed with the software package Statistica 7.0 for Windows, SPSS, and statistical package R.Results Patients of group 2 were older, more frequently had functional class (FC) III CHF and less frequently FC I CHF compared to group 1. Women and patients with preserved left ventricular ejection fraction (LV EF) prevailed in both groups. Results of the Cox proportional hazards model for ACD, CVD, death from ADHF, and the composite mortality index showed that belonging to group 2 was an independent predictor for increased risk of death (р<0.001). An increase in CCS score by 1 also increased the risk of death (р<0.001). Baseline CHF FC and LV EF did not influence the mortality in any model. Female gender and a higher value of 6-min walk test (6MW) independently decreased the risk of all outcomes except for CVD. An increase in systolic BP by 10 mm Hg reduced risk of all fatal outcomes. At two years of follow-up in groups 2 and 1, ACD was 29.9 % and 10.2 %, (OR, 3.7; 95 % CI: 2.6–5.3; p <0.001), CVD was 10.4 % and 1.9 % (OR, 5.9; 95 % CI: 2.8–12.4; p<0.001), death from ADHF was 18.1 % and 6.0 % (OR, 3.5; 95 % CI: 2.2–5.5; p<0.001), and the composite mortality index was 25.2 % and 7.7 % (OR, 4.1; 95 % CI: 2.7–6.1; р<0.001). Analysis of all outcomes by follow-up period (3 and 6 months and 1 and 2 years) showed that the difference between groups 2 and 1 in risks of any fatal outcome was maximal during the first 6 months.Conclusion The follow-up in the system of specialized medical care reduces risks of ACD, CVD, and death from ADHF. The first 6 months following discharge from the hospital was a vulnerability period for patients after ADHF. The CCS score impaired the prognosis whereas baseline LV EF and CHF FC did not influence the long-term prognosis after ADHF. Protective factors included female gender and higher values of 6MW and systolic BP.
