Case Report: Microsurgical clipping of a multilobular fenestrated anterior communicating artery aneurysm: technical challenges with video analysis.

ABSTRACT:

Background

The anterior communicating artery (AComA) is a common site for intracranial aneurysms due to its complex vascular architecture. Fenestrations in the AComA, observed in 7.5%-40% of cases, can disrupt normal blood flow, which increases turbulence and shear stress and heightens the risk of aneurysm formation.

Case description

We report the case of a 67-year-old female who presented with headaches. Imaging revealing a 10 mm unruptured multilobular aneurysm arising from the AComA. Microsurgical clipping was performed via a right pterional craniotomy. The fenestrated nature of the AComA only became apparent after intraoperative full dissection of the AComA complex. Intraoperative Doppler ultrasound and indocyanine green angiography were used to evaluate the vascular ana
