Research into the pattern and variation of brain arteries in wild rabbit involved 43 brains. The main source of blood supply to the brain in rabbit are vertebral arteries and the basilar artery, formed as a result of their anastomosis, as well as internal carotid arteries the branches of which form the arterial circle of the brain. Variation in descent concerns mostly the pattern of descent of ...

In previous studies of the role of tissue plasminogen activator (tPA) in the lung inflammatory response, we observed that tPA expression was present exclusively in the small arteries and arterioles within the lung and absent from the capillaries, veins, and large pulmonary arteries. To define more completely the expression pattern of tPA, we evaluated the distribution of this protein during pre...

Presently described is a case of subacute subclavian artery thrombosis treated with rheolytic thrombectomy, using the AngioJet system and direct stenting, in addition to double antiembolic filter protection of both the vertebral and brachial arteries.

The authors describe the clinical and radiologic features of pseudoaneurysms of the extracranial carotid and vertebral arteries in a 35-year-old woman, presumably resulting from trauma from previous seizures.

We report three cases that reveal an array of etiologic and radiologic findings associated with dissection of the proximal segment of the vertebral arteries. Regardless of etiology, the proximal segment may be the principal site of dissection in these vessels.
