Extracranial-intracranial arterial bypass in the treatment of inoperable giant aneurysms of the internal carotid artery. Report of a case.

A case of a giant aneurysm of the internal carotid artery (ICA) was treated with ICA ligation and extracranial-intracranial arterial bypass. The anastomosis was done before full occlusion of the cervical ICA, and the patient was followed with serial angiographic studies. The result obtained and the data from the literature of the last four years are discussed.
