Concomitant renal endarterectomy and aortic reconstruction

J Vasc Surg. 1994 Sep;20(3):331-6; discussion 336-7. doi: 10.1016/0741-5214(94)90130-9.


Purpose: This retrospective study is to determine the efficacy and durability of renal endarterectomy in patients undergoing simultaneous aortic reconstruction. In addition, the operative risk to patients with symptomatic and asymptomatic renal artery stenosis is evaluated.

Methods: The results of a retrospective study of 101 patients who underwent combined procedures are presented. All patients demonstrated at least a 75% stenosis of the renal artery ostium by arteriography and underwent surgical repair of aneurysmal (n = 33) or aortic occlusive (n = 68) disease. The indications for renal revascularization were hypertension necessitating multiple medications (47%), hypertension combined with renal insufficiency (18%), renal insufficiency alone (5%), and asymptomatic stenosis (30%). Blood pressure and antihypertension medications were monitored during the follow-up period (mean 3.3 years).

Results: The perioperative mortality rate was 1%, with a postoperative morbidity rate of 15%. The conditions of 74% of patients with hypertension were improved or cured, 23% were unchanged, and 3% were worse after surgery. Systolic and diastolic blood pressure in all patients remained significantly diminished during follow-up visits at 3 months, 6 months, 1 year, 3 years, and 6 years (p < 0.01). There was no significant improvement in serum creatinine levels in patients with preexisting renal insufficiency. A small but statistically significant decrease in systolic blood pressure and serum creatinine level was noted after operative intervention in the symptom-free patients (p < 0.005). There were no deaths in the asymptomatic subgroup, and significant azotemia did not develop in any of these patients after operation.

Conclusions: Renal endarterectomy is an effective and durable method of renal revascularization. Furthermore, it is a technique that can be safely combined with aortic surgery and can be considered in the treatment of high-grade, asymptomatic lesions in patients undergoing aortic reconstruction.
