Percutaneous transluminal angioplasty of renal artery stenosis
Acta Radiologica: Diagnosis
|January 1, 1981
Insights
Percutaneous transluminal angioplasty effectively treated renal artery stenosis in 7 patients. Most patients experienced normalized blood pressure post-procedure, with sustained results in the majority during follow-up.
Area of Science:
- Cardiology
- Nephrology
- Vascular Surgery
Background:
- Renal artery stenosis (RAS) is a significant cause of secondary hypertension.
- Atherosclerosis and fibromuscular dysplasia are primary etiologies of RAS.
- Percutaneous transluminal angioplasty (PTA) is a potential treatment for RAS.
Purpose of the Study:
- To evaluate the efficacy of PTA in patients with hypertension and RAS.
- To assess the outcomes of PTA in atherosclerotic versus fibromuscular RAS.
- To determine the durability of blood pressure normalization after PTA.
Main Methods:
- Seven patients with hypertension and RAS underwent PTA.
- Patients had either atherosclerotic (3) or fibromuscular (4) disease.
- Success of balloon dilatation and blood pressure response were monitored.
Main Results:
- Successful balloon dilatation was achieved in all 7 patients.
- Blood pressure normalized within 5 days in 6 patients.
- Sustained blood pressure normalization was observed in 5 patients at 3-10 months follow-up.
Conclusions:
- PTA is a highly effective treatment for hypertension secondary to RAS.
- The procedure offers durable blood pressure control in most patients.
- PTA is a viable option for both atherosclerotic and fibromuscular RAS.
Abstract:
Percutaneous transluminal angioplasty was performed in 7 patients with hypertension and renal artery stenosis, caused by atherosclerosis in 3 patients and fibromuscular disease in 4. The balloon dilatation was successful in all patients. In 6 patients the blood pressure was normalized within 5 days after the procedure, and remained so in 5 on follow up 3 to 10 months later.
