Infrarenal Aortic Infection and Rupture of a Pseudoaneurysm Secondary to Migration of Proximal Aortic Patch: Case Report and Literature Review

Aneurysm formation at the site of prior aortic coarctation patch repair is well documented. Migration of the patch though to the infrarenal aorta, as in this case, with subsequent aortitis and pseudoaneurysm formation has not been described. A 16 y old boy who was operated at the age of 10 for his aortic coarctation, presented with sepsis and abdominal pain. CT scan confirmed the presence of aortitis and an aortic pseudoaneurysm. This was treated with resection of the infrarenal aorta and replacement with superficial femoral vein. The PTFE patch from the previous coarctation repair was found and extracted from the infrarenal aorta.
