This report concerns a case of dolichoectasia of the anterior cerebral artery. The authors present the angiographic and scintigraphic pictures. The clinical symptoms were connected with ischaemia in the region supplying by the anterior cerebral artery and seemed to indicate expanding process.
Computerized tomography is much more accurate in detection of intracranial calcifications than the classic radiological methods since in makes possible demonstration of small calcifications invisible on plain films. The diagnosis of intracranial calcifications in computerized tomography depends on the size and position of calcifications and on the thickness of the visualized strate. Computerized tomography makes also possible qualitative as well as quantitative assessment of the calcifications and their relation to the nervous tissue and fluid spaces of the brain. In many cases it enables diagnosis to be made without the necessity of carrying out further neuroradiological investigations with contrast media.

The authors describe three different varieties of collateral circulation via the so called arterial network of the nape of the neck in patients with proximal subclavian artery occlusion. Attention is called to the importance of cervical veins visualization for the evaluation of the efficiency of the collateral circulation and prognosis about the further state of the patient. The authors propose a modification of angiography with additional films taken of the subclavian area in late arterial phase making possible to demonstrate the site of subclavian artery occlusion during carotid angiography.
Two patients are described with large intracranial arteriovenous angioma with minimal neurological symptoms. The first patient suffered from repeated right fronto-temporal headache. Migraine was diagnosed and he was treated with analgesic drugs. We carried out scintigraphic investigation and computerized tomography of the brain. The results of these examinations suggested the presence of large brain lesion (tumour or vascular malformation). Bilateral carotid angiography and aortic arch angiography were done in this patient. A large arteriovenous angioma was discovered in the right occipital area. The second patient complained of throbbing headaches. A bruit could be heard over the left eye which was exophthalmic. Angiograms showed a carotid-cavernous fistula on the left side and a large angioma in the fronto-parietal area. The angioma was clinically "silent". It diminished the symptoms of the carotid-cavernous fistula through the uptake of blood. Both patients were regarded as unsuitable for surgery. The reasons were the great dimension of these angiomas and a large number of supplying arteries.
Using contrast and Doppler ultrasonic diagnostic methods the authors examined 78 internal carotid arteries in 67 patients with cerebral circulatory disturbances. Ultrasonographic assessment of the blood flow in the internal carotid arteries was done in direct study of these arteries, and indirect study through the periorbital branches of the ipsilateral ophthalmic arteries. The results of USG-D examinations of internal carotid arteries were compared with their angiograms showing in 15 cases uneven outlines of the lumen, in 24 cases arterial loops, in 29 minor narrowing (21-40%), in 10 - moderate narrowing (41-70%). In the group of arteries with uneven lumen outlines USG-D examination showed impaired blood flow in 86.7% of cases, in the group of arterial loops--in 91.7% of cases, in the group of minor narrowing--in 86.2%, in the group of moderate narrowing--in 100% of cases. In all, out of 78 internal carotid arteries with angiographically confirmed abnormalities in 70 cases (89.7%) Doppler study suggested presence of lesions. In 24 cases (30.7%) disturbances of blood flow dynamics in the internal carotid artery caused an atypical result of the carotid compression test carried out during examination of opthalmic arteries. The obtained results indicated a high usefulness of Doppler test in the diagnosis of minor and moderate abnormalities of the internal carotid arteries.
