Ahead of Print: Cerebral Bypasses for Complex Aneurysms and Tumors

Background: Various techniques of cerebral bypasses are used in the treatment of aneurysms and tumors.

Objective: To study long-term clinical and radiological outcome of various bypass types, and analyze techniques used in the management of long-term graft problems.

Methods: A consecutive series of patients who underwent revascularization during a five-year period was analyzed for indications, graft patency, and neurological outcomes. Potential risk factors for bypass problems and the management of bypass stenosis were studied.
