How I do it: superficial temporal artery to middle cerebral artery bypass for treatment of giant middle cerebral artery aneurysm

Abstract

Background: Giant middle cerebral artery aneurysms are frequently anatomically complicated. Trapping may yield poor outcome, and bypass revascularization is often necessary as an adjunctive treatment to preserve flow.

Method: The technical nuances of superficial temporal artery to middle cerebral artery bypass are described in the setting of clip reconstruction of giant middle cerebral artery (MCA) aneurysm. In addition to an operative video, the anatomy and surgical technique are demonstrated in virtual reality to enhance the didactic clarity.

Conclusion: Meticulous technique is paramount for successful superficial temporal artery MCA bypass. Along with clip reconstruction, it is a critical part of the treatment of complex, giant MCA aneurysms.

Keywords: Clip reconstruction; Giant aneurysm; STA-MCA bypass.
