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.

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.

Carotid And Vertebral Arteries

Spontaneous dissection of the major arteries of the neck is known to increase the risk of stroke or transient ischaemic attack in young and middle-aged adults. Most of the reported cases of arterial dissections in the neck involve one or both paired extracranial carotid or vertebral arteries. Spontaneous dissection of the bilateral internal carotid and vertebral arteries is extremely rare. We report a case of spontaneous bilateral internal carotid artery and vertebral artery dissection while using a prescribed pill for weight loss which contained amphetamine derivative. A review of literature is also provided.

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.

Internal Carotid Arteries

Moyamoya disease is characterized by severe stenosis at the ends of the bilateral internal carotid arteries and the development of collateral circulation. The disease is very diverse in terms of age at onset, onset patterns, radiological findings, and genetic phenotypes. The pattern of onset is mainly divided into ischemic and hemorrhagic onsets. Recently, the opportunity to identify asymptomatic moyamoya disease, which sometimes manifests as nonspecific symptoms such as headache and dizziness, through screening with magnetic resonance imaging has been increasing. Various recent reports have investigated the associations between the clinical features of different onset patterns of moyamoya disease and the corresponding imaging characteristics. In this article, we have reviewed the natural history, clinical features, and imaging features of each onset pattern of moyamoya disease.

Among 350 surveyed deformations of internal carotid arteries revealed in 38.6% of cases. At pathological deformation observed acceleration of flow speed indicators from 55% to 65% in part of tortuosity, average value of systolic speeds of a blood flow was 166±28.3 cm/s at the left and 174±30.2 cm/s at the right side. In vertical position in 31.6% of cases at pathological deformation observed transfor mation of tortuosity form. deformation corners became blunt, the gradient of flow speed indicators decreased or was absent, in some cases course of internal carotid arteries became rectilinear. Artificial deformations of vertebral arteries course revealed in 79.4% of people, average value of systolic speed of a blood flow was 92±15.3 cm/s at the left and 76±12.5 cm/s at the right side. In vertical position in deformations of the vertebral arteries, which carried to pathological, in 28.8% of cases a form of deformation was transformed to unpathological tortuosity. duplex sonography in vertical position in patients with tortuosity discovered new approaches in diagnostics of pathological deformations and defines indications to operative treatment.

Moya-Moya disease is a rare progressive chronic cer-ebrovascular disease characterized by a narrowing of the lumen of the intracranial segments of the internal carotid arteries, as well as the initial segments of the anterior and middle cerebral arteries with the devel-opment of a network of small vascular anastomoses. Violations of blood supply due to occlusion lead to the development of ischemic strokes in the correspond-ing pools, and ruptures of vascular anastomoses - to the development of hemorrhagic strokes, causing a variety of neurological disorders. The article presents a clinical case of Moya-Moya disease in a 31-year-old patient. The disease was manifested by acute disorders of cerebral circulation in ischemic and hemorrhagic types. The diagnosis was made in accordance with the diagnostic criteria of the disease based on the data of endovascular cerebral angiography.
