Abdominal aortic coarctation: Surgical treatment of 53 patients with a thoracoabdominal bypass, patch aortoplasty, or interposition aortoaortic graft

A, Suprarenal abdominal aortic coarctation (bracket) with superior mesenteric artery stenosis (arrow) and (B) bilateral renal artery ostial stenoses (arrows). Note common trunk of lower lumbar artery (arrow). Preoperative computed tomographic angiography (CTA) (anterior and posterior projections, respectively).

Intrarenal abdominal aortic coarctation with bilateral artery stenoses (arrows). Preoperative aortogram.

Infrarenal abdominal aortic coarctation with an associated spontaneous pseudoaneurysm (arrow). Preoperative aortogram.

A, Suprarenal coarctation (bracket) with superior mesenteric artery stenosis (arrow). Preoperative magnetic resonance angiography (MRA). B, Thoracoabdominal bypass (broad arrow) with aortic implantation of superior mesenteric artery (arrow). Postoperative computed tomographic angiography (CTA).

A, Suprarenal coarctation (bracket) with bilateral renal artery ostial stenoses. Preoperative MRA. B, Patch aortoplasty (broad arrow) with aortic diameter exceeding that of uninvolved proximal and distal aorta. Reimplantation of the renal arteries accompanied the aortic reconstruction. Postoperative computed tomographic angiography (CTA).
