Bypass for Giant Aneurysms
In the treatment of giant aneurysms by carotid ligation and simultaneous extracranial-intracranial bypass, there are various opinions as to when the cervical internal carotid artery should be occluded: immediately after the bypass has been completed82, one day later143, within 1–2 days69, within 2–3 days23, 174, or within 7–10 days48. What is agreed, however, is that a high pressure gradient in the area of the anastomosis is desirable, i. e., a reduction of the carotid flow is aimed for from the start.
