Surgical Treatment of Renal Fibromuscular Dysplasia in a Young Child

Abstract EN

During a routine checkup in a 10-year-old male with Attention-Deficit Hyperactivity Disorder, blood pressure of 180/120 mmHg was found.

Physical examination was completely normal.

Ultrasound examination showed poststenotic dilatation of the left renal artery which was confirmed by CT-angiography showing a short, high grade stenosis of the left renal artery.

Percutaneous Transluminal Angioplasty of the stenosis was not successful and therefore the stenosis was excised with reimplantation of the renal artery in the aorta.

Pathological examination of the excised segment showed media-type Fibromuscular Dysplasia (FMD).

Six years after surgery, the kidney is completely normal regarding size and function.

There are no signs of restenosis of the left renal artery.

Nevertheless, the hypertension remained although less severe and requiring less medication.
