真の腕頭動脈瘤に対するハイブリッド修復：症例報告

A 74-year-old man with hypertension and hyperuricemia was incidentally diagnosed with a 39-mm brachiocephalic artery aneurysm. Because of a sufficient proximal sealing zone, a hybrid repair was performed, consisting of a right common carotid-axillary bypass with a prosthetic graft, followed by endovascular exclusion using covered stents, a vascular plug, and coils. Completion angiography confirmed complete aneurysm exclusion without endoleak and satisfactory bypass flow. The postoperative course was uneventful. Computed tomography (CT) angiography demonstrated persistent aneurysm exclusion without endoleak and a patent bypass. At 12 months, plain CT confirmed no aneurysm enlargement.
