Aim of the study To present our experience in the treatment of iatrogenic dissections of extracranial internal carotid and vertebral arteries with the Neuroform Atlas stent. Materials and methods Between January 2017 and February 2018 we treated iatrogenic dissections of three internal carotid arteries and three vertebral arteries. These iatrogenic dissections occurred during the endovascular treatment of ruptured and unruptured intracranial aneurysms. The indication for stenting was haemodynamically significant, flow-limiting dissection with threatening flow arrest. In all six cases, the dissections were treated by placement of Neuroform Atlas stents in the dissected segments of internal carotid or vertebral arteries. Deployment of the stent was followed by the usual dual antiplatelet regimen. Results Single or multiple Neuroform Atlas stents were deployed without any technical difficulties, and blood flow was restored immediately after placement of the stents in all six cases. Midterm follow-up (6–8 months) showed complete reconstruction of the shape and lumen of all treated arteries, with negligible intimal hyperplasia. Conclusion Our results indicate that a favourable outcome can be achieved by treating iatrogenic dissections of extracranial internal carotid and vertebral arteries with the Neuroform Atlas stent.

Spontaneous cervical arterial dissection (SCAD) is a non-traumatic tear or disruption in the wall of the internal carotid arteries or the vertebral arteries. It accounts for about 25% of strokes in patients aged under 45 years. Awareness of its clinical features and advances in imaging over the last two decades have contributed to earlier identification of this condition. SCAD has become the commonest form of vascular lesion identified in the cervical carotid and vertebral arteries, second only to atherosclerosis. This review is an update on the epidemiology, vulnerable arterial segments, risk factors, clinical features, diagnosis, current treatment and prognosis of SCAD.

We report our experience with endovascular treatment of supra-aortic arteries and follow-up results in patients with Takayasu's arteritis (TA) presenting with neurological symptoms. Of the 20 patients with TA who underwent cerebral angiography for neurological manifestations between May 2002 and May 2009, 12 (11 females, one male; mean age, 39 years; range 31–56 years) underwent endovascular treatment and evaluated outcome for 21 lesions, including nine common carotid arteries, four vertebral arteries, four subclavian arteries, two internal carotid arteries, and one brachiocephalic artery. Eight patients underwent multiple endovascular procedures for different lesions in single or multiple stages. Mean angiographic and clinical follow-up durations were 34 months (range, 11–79 months) and 39 months (range 11–91 months), respectively. Technical success was achieved for 20 procedures in 11 patients. One procedure failed, with 50% residual stenosis after stenting due to dense calcification of vessel walls. There were no procedure-related complications. Restenosis occurred at two lesions in two patients were treated by re-stenting. Asymptomatic occlusion occurred at two lesions in one patient. Ten patients remained in 0–1 on the modified Rankin scale (mRs) during mean 39 months. One patient, however, had a score of 3 on mRs due to a traumatic contusion during follow-up. One patient died from cardiac failure 36 months after successful angioplasty. Our data suggest that endovascular treatment of symptomatic supra-aortic lesions of TA is effective and durable in selected patients with neurologic symptoms.

Background The aim of this study was to report our single centre experience with the Medina Embolic Device (MED). Methods We performed a retrospective analysis of prospectively collected data to identify all patients treated with the MED. A total of 14 aneurysms (non-consecutive), in 13 patients, were treated including one ruptured and one partially thrombosed aneurysm. Fundus diameter was ≥5 mm in all cases. We evaluated the angiographic appearances, the clinical status, complications, and the need for adjunctive devices or repeat treatments. Results Aneurysm location was cavernous internal carotid artery (ICA; n = 1), supraclinoid ICA ( n = 1), terminal ICA ( n = 2), anterior communicating artery (AComA; n = 4), A2–3 ( n = 1), M1–2 junction ( n = 1), posterior communicating artery (PComA; n = 1), superior cerebellar artery (SCA; n = 1), and basilar tip ( n = 2). The average aneurysm fundus size was 8.6 mm (range 7–10 mm) and average neck size 3.75 mm (range 1.9–6.9 mm). Immediate angiographic results were modified Raymond–Roy occlusion classification (mRRC) I n = 2, mRRC II n = 1, mRRC IIIa n = 2, mRRC IIIb n = 2, the remaining 7 aneurysms showed complete opacification. At follow-up angiography (mean 5 months) mRRC I n = 5, mRRC II n = 5, mRRC IIIa n = 3, and persistent filling was seen in 1 aneurysm. Overall, four patients had repeat treatment and one is pending further treatment. Of the aneurysms treated with more than one MED, 75% showed complete occlusion at 6-month follow up whereas only one aneurysm treated with a single device showed complete occlusion. Overall, three patients had temporary complications and there were no deaths. Conclusions The MED is an intra-saccular flow-diverting device with satisfactory angiographic results and an acceptable safety profile. Use of a single MED cannot be recommended and further longer term studies are needed prior to widespread clinical use.

In a prospective study of the natural development of total cerebral blood flow volume (CBFV), the common, external and internal carotid and vertebral arteries were examined in 94 healthy children and adolescents between 3 and 18 years of age (sex and age evenly distributed) using a 7.0-MHz transducer of a computed sonography system. Intravascular flow volumes were calculated with the product of angle-corrected time-averaged flow velocity and the cross-sectional area of the vessel. CBFV was determined as the sum of flow volumes in the internal carotid and vertebral arteries of both sides. CBFV increased significantly between 3 and 6.5 years of age (from 687 ± 85 to 896 ± 110 ml/min; age correlation, p ≤ 0.01) and declined thereafter ( p ≤ 0.001) to a constant level of ∼700 ml/min at 15 years of age. There was no difference in CBFV between sexes. The proportion of bilateral vertebral artery flow volume in total CBFV decreased significantly between the ages of 3 and 18 years ( p ≤ 0.001). As the flow volumes of the external carotid arteries increased markedly from childhood to adulthood, flow volumes of the common carotid arteries were not representative of CBFV. Intrasession test-retest correlation of CBFV was high ( r = 0.89, p ≤ 0.0001). Reference data for the childhood years presented here and previously described results from healthy adults allow us to outline the natural evolution of CBFV in humans. The reliability of the method has already been demonstrated. Thus, it may now be introduced into clinical application.

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.

Internal Carotid Arteries

Rarely, the external and internal carotid arteries arise separately from the brachiocephalic trunk and right subclavian artery (SA) or the aortic arch and reflect the absence of a common carotid artery (CCA). We report a 45-year-old man with absent right CCA associated with aberrant right SA, an extremely rare combination, diagnosed by computed tomography (CT) angiography during follow-up for postoperative aortic dissection. Retrospective careful observation of preoperative postcontrast CT revealed the absent right CCA. Previously reported arch variations associated with absent CCA include cervical aortic arch, double aortic arch, and right aortic arch.
