Aim. The aim of this study was to evaluate the technical success and clinical outcome of surgical revascularization, angioplasty and/or stenting for renal artery stenosis (RAS) in patients with renovascular hypertension (RVH). The secondary aim was to identify independent negative predictors of blood pressure control after successful renal revascularization.
Methods. From January 1998 to July 2006, we treated 97 cases of RAS in 83 RVH patients. Inclusion criteria were RAS ≥80% associated with hypertension refractory to medical control with at least three drugs including a diuretic. Therapeutic options were surgical revascularization in 15 cases (11 renal endarterectomies, 4 aortorenal bypasses) and endoluminal treatment in 82 (14 balloon angioplasties, 68 stents).
Results. Technical success was 100% for both surgical and endovascular procedures; 13 cases of restenosis (≥80%) were detected: 12 (14.6%) in the endoluminal group and one (6.6%) in the surgical group (P=0.68). During the follow-up period (average 37 months, range 6-94), blood pressure control improved in 43% of patients, disease stabilized in 37% and the natural course of RVH deteriorated in 20%. Multivariate Cox regression analysis showed that only a long history of antihypertensive drug use was a predictor of inefficacy of blood pressure control after revascularization (P<0.04).
Conclusion. The complete resolution of RVH associated with severe RAS appears unrealistic in several cases. Early and long-term results in terms of technical success and restenosis were acceptable and similar for surgical and endovascular renal intervention. An early diagnosis of RVH could improve the control of hypertension after successful renal revascularization.
