Aim of study. To specify the peculiarities in spatial arrangement of arterial branches in the area of anterior perforated substance. Material and methods. The work was carried out using brain material of 25 people of both genders from the archive of the Department of Anatomy at the FSBEI HE Ryazan State Medical University MOH RF. In order to verify the arteries before formaldehyde fi xation of brain, their injection with gelatine solution was performed. Th e peculiarities in origin of central arteries from the internal carotid artery, middle cerebral artery, anterior cerebral artery as well as their calibres and quantity were examined. Results. The study has shown that the spatial arrangement of the perforating arteries in the anterior perforated substance depends on the particular site of origin. Th e origins of arterial branches flowing through the anterior perforated substance are the internal carotid artery, anterior cerebral artery, middle cerebral artery and anterior choroidal artery. Perforating branches originating from the internal carotid artery were registered in both hemispheres in 98 % of the cases. Unilateral (left ) absence of branches originating from the C4 segment was only noted in one case. The largest quantity of arteries originated from M1 segment of the middle cerebral artery. Th erewith, the majority of the branches belonged to the lateral group exceeding the quantity of such branches in the medial group by 2.3 times on average. Th ereat, the quantity of branches in each group showed no valid diff erence in relation to the side of the body. Conclusion. Knowledge of the anatomy of the anterior perforated substance, the peculiarities in spatial arrangement of the branches of middle cerebral artery and the anterior choroidal artery is important and is of interest for clinicians from the perspective of diagnosis and timely treatment of cerebral tumours and aneurisms of its arterial ring

Abstract The perforating branches of the internal carotid artery (ICA) were examined in 30 forebrain hemispheres. These branches were present in all the cases studied, and varied from 1 to 6 in number (mean, 3.1). Their diameters ranged from 70 to 470 Mm (mean, 243 Mm). The perforating branches arose from the choroidal segment of the ICA, that is, from its caudal surface (52.3%), caudolateral surface (34.1%), or caudomedial surface (13.6%). They rarely originated from the bifurcation point of the ICA (10%). The distance of the remaining 90% of the perforators from the summit of the ICA measured between 0.6 and 4.6 mm. The perforating branches most often originated as individual vessels, and less frequently from a common stem with another vessel or by sharing the same origin site with another perforator or with the anterior choroidal artery. The bifurcation of the ICA, which is a frequent site for cerebral aneurysms, is surrounded by many perforating branches. Hence, great care must be taken to avoid damage to these important vessels during operations in that region.

We report a case of anterior choroidal artery territory infarction due to internal carotid artery dissection presumably caused by scuba diving. A 44-year-old man presented with left facial palsy and hemiparesis. He had a history of scuba diving for 18 months. His last dive was 7 days ago, and he skipped decompression practice at that dive. We assumed that repetitive traumas and microbubbles during scuba diving, which made endothelium vulnerable to damage may have caused a carotid dissection.

Abstract A case of the de novo formation of an aneurysm in a young woman is presented. At age 13 years, she had a spontaneous subarachnoid hemorrhage. Cerebral angiography showed an aneurysm of the bifurcation of the left internal carotid artery and a small aneurysm of the left anterior choroidal artery. At surgery, the aneurysm of the internal carotid artery was clipped, and the aneurysm of the left anterior choroidal artery was wrapped with muslin. Thirteen years later, the patient had another subarachnoid hemorrhage. Cerebral arteriography showed four aneurysms that had developed at previously angiographically normal sites. This case suggests that young patients with aneurysms might benefit from follow-up angiography in search of late aneurysm formation.

Choroidal Artery

The pathogenesis of anterior choroidal artery (AChA) territory infarction includes various mechanisms, but hemodynamic causes are rare and difficult to diagnose. 77-year-old man, who had moderate left ICA stenosis and he had treated with STA-MCA bypass surgery for severe symptomatic left MCA stenosis 10 years earlier, was admitted with right hemiparesis and confused state. On admission, magnetic resonance imaging and angiography demonstrated patent bypass, but severe stenosis of left ICA with no opacification of the left AChA and A1 portion of the left ACA. Diffusionweighted imaging demonstrated ischemic lesion in the left corona radiata. Together with clinical findings, hemodynamic ischemia of the AChA region was suspected and left carotid artery stenting resulted in prompt improvement of symptoms. Hemodynamic ischemia of the AChA territory is rare, however, should be considered as a potential target of treatment when the ipsilateral ICA, A1 and M1 show stenoocclusive lesions.
