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

Coil Embolization for an Aberrant Left Subclavian Artery Aneurysm with Kommerell’s Diverticulum；Report of a Case

はじめに　鎖骨下動脈瘤は動脈瘤全体の0.13％，末梢動脈瘤の3.5％とまれである1）．われわれは，右大動脈弓・Kommerell憩室を合併した左鎖骨下動脈囊状瘤に対して，左鎖骨下動脈（LSA）遮断試験を施行後に瘤内コイル塞栓術を行った1例を経験したので報告する．

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.
