The basic microvascular anatomy of the human dura is described. The named dural arteries give rise to two outer anastomotic sets of vessels. From the outer arteries, penetrating vessels descend to supply a rich capillary network located near the arachnoid. Arteriovenous shunts are present in the midportion of the dura, which may function to bypass the(More)
Carotid arterial puncture during percutaneous retrogasserian procedures is a common but usually harmless complication. Strokes, resulting presumably from carotid artery thrombosis, have been reported previously following percutaneous retrogasserian coagulation. The authors report two cases of carotid-cavernous fistula, one following percutaneous(More)
Cyanoacrylate is a satisfactory material for therapeutic embolization, but it has the disadvantage of not being radiopaque and polymerizing within 1 sec after contact with ionic materials. Its behavior was modified with varying concentrations of iophendylate and were able to satisfactorily control its polymerization from 1 to 30 sec. This control should(More)
The angiographic evaluation of the transient ischemic attack has been technically difficult, time consuming, and complication prone because of underlying arteriosclerosis and other medical diseases. The examination described depends upon small soft catheters, dynamic fluoroscopy for positioning, and selective magnified views of the arteries needed for(More)
PURPOSE To determine the maximum dose-intensity of cisplatin (DDP) that could be administered by selective intraarterial (IA) infusion in combination with systemic sodium thiosulfate neutralization to patients with head and neck carcinoma. PATIENTS AND METHODS Forty-two patients (23 untreated stage III/IV, 19 recurrent) received highly selective IA DDP,(More)
Advances in vascular radiology techniques for superselective arterial infusions and methods to overcome systemic toxicity from high-dose cisplatin chemotherapy encouraged us to reevaluate the effects of rapid regional cisplatin infusion for patients with head and neck malignancies. Twenty patients (17 carcinomas, three sarcomas) received high-dose cisplatin(More)
