Renal Artery Stenosis With Severe Hypertension: A Case Report
Abstract
Background: Renal artery stenosis (RAS) is found in 77% of hypertensive patients and is responsible for 1-2% of systemic hypertension. Arteriosclerotic renal artery disease is commonly seen in older patient and rarely seen below 50years, while fibromuscular dysplasia is seen in young adult female with age range of 15-30years.
Objectives: A case of incidentally diagnosed congenital RAS with severe hypertension in a 28-year old lady and the role of radiology in diagnosis of RAS is reported.
Case: A 28-year old lady who presented to the general outpatient department of Aminu Kano Teaching Hospital with 3days history of headache, dizziness and malaise. The patient was not a known hypertensive or diabetic. Examination revealed high blood pressure of 160/120mmHg. Abdominal ultrasound revealed a shrunken right kidney, Intravenous urography showed delayed nephrogram and delayed excretory phase with decrease density in the collecting systems, computed tomogram confirmed shrunken right kidney. Digital subtraction angiography (DSA) showed the stenosed right renal artery involving the ostium and the proximal one-third.
Conclusion: Renal artery stenosis should be suspected in young people with unexplained hypertension and radiologic investigations are key in confirming diagnosis.
