How I do it: surgical clip reconstruction of a large, partially thrombosed, ruptured middle cerebral artery aneurysm.

Abstract

Ruptured large and partially thrombosed aneurysms are challenging lesions to treat successfully. We describe the surgical treatment of a large, ruptured partially thrombosed middle cerebral artery (MCA) aneurysm. Once the Sylvian fissure is dissected, temporary clips are placed, and the clot is evacuated with simple microsuction and ultrasonic aspiration. The aneurysm is then carefully clip reconstructed to avoid compromise of the parent vessels. In cases of surgical clipping of large, thrombosed aneurysms, it is important to be aware of a few, but critically important, pitfalls to ensure successful outcome.
