A combined bilateral approach to anterior communicating artery aneurysm.

AIM To discuss the features, feasibility, and safety of a combined bilateral approach in the endovascular treatment of intracranial anterior communicating artery (ACoA) aneurysm. MATERIAL AND METHODS We performed a retrospective analysis of the clinical data of patients with ACoA aneurysm treated with a combined bilateral approach. RESULTS We successfully embolized aneurysms in nine patients with intracranial ACoA aneurysm using a combined bilateral approach. All treated patients had an open ACoA connecting with the bilateral anterior cerebral arteries. CONCLUSION Because the ACoA connects the intracranial arteries in both hemispheres, patients with ACoA aneurysm can be endovascularly treated with a combined bilateral approach. Notably, surgeon experience and dexterity play important roles in the success of this procedure.
