Pregnancy and delivery in women with renovascular hypertension due to multiple intrarenal microaneurysms: a report of two cases.

We herein report two cases of pregnant women who had chronic hypertension caused by renovascular hypertension due to multiple intrarenal microaneurysms from unknown causes, who had similar clinical courses. During the first pregnancy, both women developed uncontrollable severe hypertension that finally led to superimposed preeclampsia; however, during the second pregnancy, the blood pressure was controlled well, and the clinical courses were uneventful. These cases suggest that an uneventful term delivery may be achieved with adequate blood pressure control in pregnant women with chronic hypertension caused by renovascular hypertension, and a prior eventful clinical course of delivery does not affect the subsequent clinical course.
