Cutting Balloon Angioplasty (CBA) for the Treatment of Renal Artery Fibromuscular Dysplasia (FMD) in Six Patients: 5-Year Long-Term Results

Abstract

Purpose: To evaluate long-term outcomes in terms of hypertension control, recurrent stenosis, and reinterventions from patients who underwent cutting balloon angioplasty (CBA) for symptomatic renal artery fibromuscular dysplasia (FMD).

Materials and methods: From 2011, six consecutive renal artery FMD women underwent CBA for poorly controlled hypertension, despite antihypertensive therapy. Follow-up consisted of blood pressure monitoring and duplex ultrasonography at 1, 6, and 12 months and thereafter annually for 5 years.

Results: All treatments were technically successful. Recurrence of hypertension was found in two patients within 12 months, and reinterventions were performed using CBA.

Conclusion: Results show the efficacy of CBA for renal artery FMD.
