Kommerell 憩室に合併した左鎖骨下動脈囊状瘤に対して瘤内コイル塞栓術を施行した1 例

A 67-year-old woman encountered a traffic accident and had chest computed tomography（CT） examination. It revealed a 24 mm Kommerell’s diverticulum associated with a right-sided aortic arch and a 15 mm saccular aneurysm of an aberrant left subclavian artery. We performed intra-aneurysmal coil embolization for the left subclavian artery aneurysm after a balloon occlusion test of the left subclavian artery. The postoperative course was uneventful.
