Evaluation of 2-mm arterial grafts for extra- to intracranial bypass in occlusive cerebrovascular disease
A scalp vessel of adequate (2-mm) diameter may not be available due to anatomic variation, previous trauma, or previous craniotomy.
Rapid anastomosis is required in cases of progressive stroke or acute stroke due to MCA or internal carotid artery (ICA) occlusion with partial neurologic deficit of 1 to 4 hr duration. Preparation of scalp vessels is tedious and may require from 1 to 3 hr of surgical dissection.
Small-diameter scalp vessels (1.0 to 1.5 mm) may not provide adequate blood flow for collateral augmentation especially in the acute or progressive cases where the 10 to 30 cm3/min rates measured following anastomosis may be insufficient to prevent infarction before the bypass has matured and the donor vessel enlarged.
