Transluminal angioplasty for renovascular hypertension complicated by pregnancy.

Percutaneous transluminal angioplasty was successfully used in the treatment of renovascular hypertension that resulted from fibromuscular hyperplasia in a 26-year-old woman who was four weeks' pregnant. The patient's BP normalized immediately. She had a normal pregnancy that terminated in the delivery of a full-term normal child. Two and a half years after the procedure, she remained normotensive without taking antihypertensive medication. Percutaneous transluminal angioplasty may be useful in the treatment of renal artery stenosis complicated by hypertension and pregnancy, where the inherent risk of toxemia endangers the life of the mother and fetus.
