HIGH-FLOW BYPASS USING NONOCCLUSIVE EXCIMER LASER-ASSISTED END-TO-SIDE ANASTOMOSIS OF THE EXTERNAL CAROTID-ARTERY TO THE P-1 SEGMENT OF THEPOSTERIOR CEREBRAL-ARTERY VIA THE SYLVIAN ROUTE - TECHNICAL NOTE

In a patient with a giant aneurysm of the basilar artery trunk, a vein graft was interposed between the external carotid artery in the neck and the P-1 segment of the posterior cerebral artery. Balloon occlusio n of both vertebral arteries was performed 3 days later. The sylvian r oute was used for the grafting procedure and the connection to the pos terior cerebral artery was made by using the excimer laser-assisted no nocclusive anastomosis technique.
