Disappearance of Aneurysm Complicating Extracranial-Intracranial Bypass Surgery: A Case Report

Year: 2010

Type: article

Abstract: Surgical revascularization through a superficial temporal artery-middle cerebral artery (STA-MCA) bypass is often performed to prevent cerebral ischemic attack. A 74-year-old man who had undergone an STA-MCA bypass presented 10 months after the bypass procedure, with an aneurysm at the anastomosis site reveled by computed tomography (CT) angiography. Follow-up cerebral angiography revealed the aneurysm was gradually growing. We wrapped the aneurysm to prevent rupture, and on the following CT angiography and cerebral angiography, the aneurysm could not be seen. Increasing hemodynamic stress of the anastomosis site may have contributed to the aneurysm’s formation, and the granulation due to the wrapping material or the mechanical spasm of the aneurysm may have contributed its disappearance.
