Acute aortic occlusion as a late complication of coarctation repair.
Late morbidity and mortality following surgical correction of coarctation of the aorta in adults are primarily related to associated cardiovascular disease, especially persistent systemic hypertension and its sequelae. complications related to the site of coarctation repair are relatively uncommon in this age group and include residual and recurrent coarctation and aneurysm formation. An unusual case is presented in which dehiscence of the proximal suture line of a Dacron tube graft resulted in a flap-valve effect, pseudoaneurysm formation, and acute functional occlusion of the aorta. The angiographic findings are described and the relevant literature reviewed.
