Bacteroides fragilis aortic arch pseudoaneurysm: case report with review

We present a case of 58-year-old woman with underlying diabetes mellitus, hepatitis C virus-related liver cirrhosis, and total hysterectomy for uterine myoma 11 moths ago, who was diagnosed ruptured aortic arch mycotic pseudoaneurysm after a certain period of survey for her unknown fever cause. After emergent surgery with prosthetic graft interposition, all her blood cultures and tissue cultures revealed pathogen with Bacteroides fragilis. Although mycotic aneurysms have been well described in literatures, an aneurysm infected solely with Bacteroides fragilis is unusual, with only eight similar cases in the literature. Here we reported the only female case with her specific clinical and management course and summarized all reported cases of mycotic aneurysm caused by Bacteroides fragilis to clarify their conditions and treatments, alert the difficulty in diagnosis, and importance of highly suspicious.

Asymptomatic pseudo-aneurysm of the aortic arch in a patient with aberrant right subclavian artery. A complication of Kommerell's diverticulum?

Kommerell's diverticulum is an aortic arch deformity associated with an aberrant subclavian artery. Symptoms related to compression of adjacent structures, dilatation of the aortic diverticulum or accelerated atherosclerosis leading to increased risks of dissection and rupture represent the indications for surgical treatment. Several surgical strategies have been used for the management of this congenital abnormality. We present the case of a 56-year-old male with a pseudo-aneurysm of a left aortic arch adjacent to a Kommerell's diverticulum at the orifice of a left subclavian artery. The patient also presented an aberrant right subclavian artery originating from the posterior wall of the ecstatic take-off of the left subclavian artery. Our surgical strategy was limited to the resection of the aneurysm without any manipulation of the aortic diverticulum and aberrant right subclavian artery, as the wall of both aorta adjacent to the saccular aneurysm and left subclavian artery was normal, the Kommerell's diverticulum was small and the patient was asymptomatic.

弓部大動脈に巨大仮性瘤を形成した穿通性粥状硬化性潰瘍ｐｅｎｅｔｒａｔｉｎｇ ａｔｈｅｒｏｓｃｌｅｒｏｔｉｃ ｕｌｃｅｒの１例

症例は72歳，男性．嗄声を主訴に耳鼻科を受診したところ反回神経麻痺を指摘され，他院での胸部単純CT検査で弓部大動脈に7×4.5cmの動脈瘤を認め加療目的で当院紹介となった．胸部造影CT検査で弓部大動脈穿孔性仮性瘤と診断され，左開胸・低体温・選択的脳灌流下に遠位弓部大動脈のhemiarch replacementを行った．瘤化のない大動脈が粥状硬化により穿通し仮性瘤を形成したことから，穿通性粥状硬化性潰瘍（penetrating atherosclerotic ulcer: PAU）が原因と診断された．検索し得た範囲では，PAUによる弓部大動脈仮性瘤に対し手術を行った報告は本邦2例目であり，極めて稀な症例として報告した．

Percutaneous occlusion of posttraumatic aortic arch pseudoaneurysm by catheter‐based delivery of thrombin

To report a patient in whom a posttraumatic pseudoaneurysm of the aortic arch was successfully treated by catheter-based delivery of thrombin with balloon occlusion of the entry tear. A 63-year-old male presented with pseudoaneurysm of the aortic arch after blunt chest trauma which was detected incidentally during routine chest X-ray. Using a percutaneous transfemoral approach, a 5 French Swan-Ganz catheter could be positioned into the aneurysm sac. Under balloon occlusion of the entry tear in order to prevent systemic embolization, 1,000 units of bovine thrombin were injected into the aneurysm sac resulting in complete occlusion of the aneurysm. Contrast-enhanced computed tomographic control showed complete thrombosis of the aneurysm over a follow-up period of 12 months. Percutaneous catheter-based delivery of thrombin is a feasible and effective minimally-invasive treatment alternative for patients with thoracic aortic pseudoaneurysms.

Combined Endovascular and Open Treatment for Infected Pseudoaneurysm of the Thoracic Aortic Arch

Infected pseudoaneurysm of the aortic arch is a rare but life-threatening condition. The conventional treatment involves cardiopulmonary bypass, prolonged vascular clamping, and an extensive bypass procedure. We report a case of infected pseudoaneurysm involving the aortic arch. The patient underwent debranching of the supra-aortic arteries and bypass surgery, followed by stent grafting the next day. The patient had good recovery, and the 1-year follow-up computed tomography scan showed resolution of the infected pseudoaneurysm.

Embolization of an Aortic Arch Pseudoaneurysm with Coils and N-ButylCyanoacrylate

Endovascular treatment strategies are evolving as viable alternatives for the treatment of aortic pseudoaneurysms. The present report describes an enlarging aortic arch pseudoaneurysm that was successfully treated with a combination of embolization with detachable coils and N-butyl-cyanoacrylate.

Treatment of aortic pseudoaneurysm with interventional procedure

Mycotic arch aneurysm and aortoesophageal fistula in a patient with melioidosis

Aortoesophageal fistula due to an aortic arch aneurysm is a rare entity with an extremely high mortality. There are few reports of successfully managed cases and even fewer of long term survival. We report a case of an aortoesophageal fistula resulting from a mycotic pseudoaneurysm of the distal aortic arch in a patient with melioidosis, its surgical management, and outcome.
