Abstract
Endovascular occlusion by various catheterization techniques was carried out to treat 13 cases of intracavernous aneurysms and cerebral arteriovenous malformations.
In four cases of giant aneurysms, internal ligation of the carotid artery was performed by the detachable balloon technique without significant complication.
The attempt at aneurysmal closure failed in two cases. In one remaining patient, the temporary occlusion of the carotid artery resulted in a marked decrease of the aneurysmal size.
Calibrated-leak balloon catheterization with fluid embolization was used to treat cerbral arterio-venous malformation.
Postoperative angiography revealed a definite decrease in shunt flow, but partial filling remained in five of six cases.
No neurologic improvement was obtained after the procedures.
