Renal artery stenosis complicated by an intraoperative rupture of renal artery: a case study

Abstract

Renal artery stenosis (RAS) is a major contributor to the prevalence of secondary hypertension. Fibromuscular dysplasia and atherosclerosis are commonly responsible for the occurrence of the disease. Medical therapy is the primary means of treatment for RAS. However, surgical interventions for revascularization are also considered, in selected group of patients, which can effectively cure hypertension and chronic kidney disease. An older man presented at Venus hospital, Surat, Gujarat with the complaints of severe dyspnea, edema, uncontrolled hypertension and renal insufficiency. He was diagnosed RAS and was operatively managed with percutaneous transluminal renal angioplasty. Written consent was taken from the patient mentioned in the study. During the procedure, the renal artery got ruptured, which was managed by placing a covered stent. The patient was successfully treated for RAS, in spite of comorbidities and intraoperative complication. In the subsequent clinical follow-up, the patient was asymptomatic. There was marked reduction in serum creatinine levels and even the blood pressure improved significantly. Absence of post-operative complications and positive recovery of the patient signifies the fact that management of renal artery rupture with a covered stent is a convenient approach in acquiring effective haemostasis. This approach can be useful in managing any sort of vessel rupture, related to revascularization procedures.
