Key Points

The aim is to evaluate a hybrid approach for treating ruptured M1 fusiform aneurysms that are difficult to reach surgically.
Utilized a double-barrel STA–MCA bypass to achieve high-flow revascularization.
Performed endovascular embolization of the parent artery after revascularization.
Focused on cases with complicated proximal exposures in adult males.
Achieved successful revascularization and parent artery occlusion.
Demonstrated safety and effectiveness in treating challenging aneurysms.
Showed potential for improved outcomes in high-risk patients.

Abstract

For ruptured giant M1 fusiform aneurysms with challenging proximal surgical exposure, a hybrid approach involving revascularization and subsequent parent artery occlusion represents a safe and effective treatment modality. The larger caliber of the STA in adult males allows for high-flow revascularization through a double-barrel bypass.
