同一内頸動脈の後交通動脈分岐部, 前脈絡動脈分岐部に動脈瘤を有する症例の外科治療  [in Japanese] Surgery for Double Aneurysms of the Internal Carotid Artery Both at the Posterior Communicating and Anterior Choroidal Artery  [in Japanese]

We report 7 cases presenting with double aneurysms originated from the junction of the internal carotid artery-posterior communicating artery and the ipsilateral internal carotid artery-anterior choroidal artery. It was equivocal in the preoperative angiogram whether 2 adjacent aneurysms were adherent or not. Meticulous dissection of the aneurysms and preservation of blood flow in the parent artery and its branches are required in direct surgery.
