Association of coarctation of the thoracic aorta with fibromuscular dysplasia of the renal arteries: a case report.

The case of a 25-year-old woman with coarctation of the thoracic aorta and combined bilateral fibromuscular dysplasia of the renal arteries is reported. Although marked hemodynamic changes induced by the coarctation were probably pre-existent, hypertension was revealed only during the last month of her first pregnancy and was spontaneously corrected 2 months post partum. Surgical treatment of the thoracic coarctation did not influence blood pressure which remained normal.
