Hemodynamic stress participates in the initiation and progression of aneurysmal degeneration. Coarctation increases flow-mediated stress on the aortic wall. We tested the hypothesis that prolonged coarctation of an infrarenal abdominal aorta (AA) segment leads to abdominal aortic aneurysm (AAA) formation in mini pigs. An infrarenal AA segment of Taiwanese Lanyu mini pigs was wrapped with an 8 m...

This paper reports a rare case of a 65-year-old woman diagnosed with a multisaccular, abdominal aortic aneurysm (AAA), 35 mm in diameter, which was revealed developing just distal to an abdominal aortic coarctation (AAC), with a 20 mmHg pressure gradient. The patient underwent corrective surgery for both lesions, with success. Intraoperatively, the aneurysm wall was found to be so thin and tran...

Bicuspid aortic valve and/or coarctation of the aorta are consistently associated with ascending aortic and para-coarctation medial abnormalities. Medial abnormalities in the ascending aorta are prevalent in other types of patients with a variety of forms congenital heart disease (CHD), such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic lef...

cating artery was first described by Robinson and demonstrated on angiography by Isherwood and Dutton, 44 cases have been reported (1, 2). Most cases demonstrate unilateral involvement and only 10 cases of bilateral involvement have been reported out of the 45 cases, including the case described in this report. Although cerebral aneurysms are frequently associated with this congenital anomaly, ...

We report a case of a 46-year old man who presented with spontaneous bright red blood per mouth for several months. The patient had history of aortic coarctation repair at age 17. Endoscopy and nasopharyngeoscopy revealed no source of bleeding. Computed tomography scan revealed the presence of thoracic aortic pseudoaneurysm with the formation of an aortobronchial fistula (ABF). This case illust...

OBJECTIVE Hemodynamic stress participates in the initiation and progression of aneurysmal degeneration. Coarctation increases flow-mediated stress on the aortic wall. We tested the hypothesis that prolonged coarctation of an infrarenal abdominal aorta (AA) segment leads to abdominal aortic aneurysm (AAA) formation in mini pigs. METHODS An asymmetric, funnel-shaped flow path was created by con...

We report the unusual presentation of coarctation of the aorta with facial nerve palsy in an infant and a child. The facial nerve palsy and hypertension resolved spontaneously after relief of the aortic coarctation. Our two cases are the first reports of unidentified coarctation of the aorta presenting as facial nerve palsy, with the infant being the youngest to be reported.

Interrupted aortic arch in adults is rare with a limited number of reported cases. We describe a case of a 53-year-old woman with interrupted aortic arch, bicuspid aortic valve, and post-interruption saccular aneurysm of the aorta. To our knowledge, this is only the second report of an adult patient with all 3 abnormalities. We also review the literature on this unusual condition and discuss it...
