A case of renovascular hypertension due to bilateral renal artery microaneurysm who succeeded in baby delivery

We report the case of a young pregnant woman with bilateral renovascular hy pertension due to renal microaneurysms from an unknown cause, who had a suc cessful delivery. Pregnancy did not affect the disease activity even in the postpartum period. Her blood pressure was maintained within the normal ran ge by administration of labetalol, Although the angiographic appearance of the symmetrical aneurysms in both renal artery beds from the interlobular t o arcuate artery levels suggested polyarteritis nodosa of multiple microane urysms in the bilateral interlobular arteries, the clinical features sugges ted other causes of renovascular hypertension, such as fibromuscular dyspla sia and/or congenital microaneurysms, We were thus unable to reach a defini tive diagnosis.
