Radiological And Clinical Fallow Up Results Of Renal Artery Stenting Or Ballon Angioplasty In Patients With Renal Artery Stenosis

Aim: To determine the primary success rate and follow up results of renal artery stenting or balloon angioplasty in controlling renovascular hypertension and renal failure in patients with renal artery stenosis. Method: Before balloon angioplasty and stenting; renal angiography and Doppler ultrasonography findings were evaluated and also findings of MRA were estimated if present.The clinical estimation of the cases were made upon to renal functions, hypertension values and the changes of the number of medicines used. Results: Balloon expandable stents were placed in 32 renal arteries of 37 patients. Balloon angioplasty were used in 7 renal arteries of 37 patients (22 men, 15 women; mean age 50.24). There were hypertension in all of the patients. In 12 patients; there were disturbed renal functions. In order to determine the activity of the cure of the disease, the patients are followed by measuring blood pressures and serum creatinin levels before and after the stenting and balloon angioplasty. Stenosis rate was 30-100% (mean 74.15%).The lesions were ostial in 15 patients, truncal in 24 patients. Mean follow up time was 21.2 months (3-84 months). Hypertension was cured in 9 (24.33%) patients, improved in 19 (51.35%).patients In 9 (24.33%) patients there was no respond. In 12 patients with disturbed renal function, 8 (22.22%) patients showed improvement, 4 (11.10%) patients showed deterioration and 4 (11.10%) patients were stable. Conclusion: Revascularization of renal artery stenosis with stenting and balloon angioplasty is a simple, efficient and safe procedure. In patients with uncontrolled hypertension and progressive renal failure; revascularization of renal ar tery stenosis with stenting and baloon angioplasty pointed out impor tant clinical benefit.
