Surgical correction of abdominal aortic coarctation and hypertension
Insights
Abdominal aortic coarctation with renal artery stenosis often causes hypertension. Surgical repair, including aortoaortic bypass and renal artery bypass, is recommended for these complex cases.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Nephrology
Background:
- Coarctation of the abdominal aorta frequently co-occurs with renal artery stenosis.
- This combination often leads to renovascular hypertension, a primary presenting symptom.
Abstract:
Coarctations of the abdominal aorta are often associated with renal artery stenosis resulting in hypertension, which is commonly the presenting symptom. Controversy exists concerning the origin of these lesions, but there is general agreement that surgical intervention is the treatment of choice. We report four patients with abdominal aortic coarctation and concomitant renal artery stenosis who required aortoaortic bypass and appropriate bypass to the renal vessels. We advise total correction in one stage and proximal renal artery bypass from native aorta or iliac artery when it is technically feasible.
