A left ventricular (LV) pseudoaneurysm is one of the complications of acute myocardial infarction. It is also reported after chest trauma, cardiac surgery, and endocarditis. We report a rare case of an LV pseudoaneurysm induced by an LV venting catheter through the right superior pulmonary vein during thoracic aortic surgery. A 77-year-old man was referred for surgical repair of a distal aortic arch aneurysm. He underwent total aortic arch reconstruction with the frozen elephant trunk technique. The early postoperative period was uneventful. Postoperative contrast computed tomography and transthoracic echocardiography (TTE) revealed a pseudoaneurysm with a narrow neck at the apex of the LV that had sub-clinically progressed. Because of the risk of spontaneous rupture, an urgent aneurysmectomy was performed via a repeat sternotomy. Under cardioplegic arrest, the pseudoaneurysm was opened and the small orifice, which communicated with the LV, was confirmed. No myocardial ischemic changes were observed around the orifice. The pseudoaneurysm was thought to be induced by endocardial laceration by the tip of the venting catheter. The pseudoaneurysm was closed by linear repair reinforced with felt strips. The patient recovered well and was discharged 18 days after the second surgery. TTE showed no recurrence of LV aneurysm at the last follow-up.

Endovascular Repair for Abdominal Aortic Aneurysm with an Ectopic Pelvic Kidney: Case Report and Procedural Consideration of the Aberrant Renal Artery

引用

World Journal of Cardiovascular Surgery 2018年第6期8卷 111-116页

作者： Kenji Sakai taiju watanabe Tetsuya Yoshida Department of Cardiovascular Surgery Hokushin General Hospital Nagano Japan

A 91-year-old female presented with a pulsatile abdominal mass. Her past medical history included hypertension and hyperlipidemia. A 6.9 cm infrarenal abdominal aortic aneurysm, with a left ectopic pelvic kidney and two aberrant renal arteries, one each from the left and right common iliac arteries was found on computed tomography. Because of the high risk of rupture, surgery was recommended and an endovascular aneurysm repair was performed. The antegrade flow of the aberrant renal artery from the left common iliac artery was preserved. The right aberrant renal artery was covered with stent graft. The patient’s serum creatinine level remained unchanged throughout the postoperative course, with an uneventful postoperative recovery.
