Surgical Revasculization for Pediatric Renovascular Hypertension Caused by Fibromuscular Dysplasia

抄録

A 4-year male was referred to our hospital for high fever. Incidentally, abnormally high blood pressure was detected. A thorough examination revealed severe stenosis at the origin of two left renal arteries and elevation of plasma renin activity as well as aldosterone level. Some lesions of previous asymptomatic brain bleeding were also revealed. Instead of using prosthetic materials, we transected renal arteries and directly anastomosed them to abdominal aorta, expecting subsequent growth of native vessels. The postoperative course was uneventful. The plasma renin activity and aldosterone level as well as the dose of antihypertensive drug decreased significantly after the operation.
