Intracranial hemorrhage in pregnant women with hypertensive disorders of pregnancy

抄録

We experienced three cases of intracranial hemorrhage in pregnant women with hypertensive disorders of pregnancy (HDP). Case 1 showed progression of chronic hypertension to superimposed preeclampsia, Case 2 was diagnosed with preeclampsia, and Case 3 was diagnosed with gestational hypertension. Intracranial hemorrhage developed at home in Cases 1 and 2, and during cesarean section in Case 3. Cases 1 and 2 were treated by hematoma removal and aneurysm clipping after cesarean section, while Case 3 elected conservative treatment. Case 1 had hypertension from the first trimester but was not diagnosed with chronic hypertension. She later developed severe hypertension but was managed as a normal pregnancy. Case 2, despite having preeclampsia, was not placed under stringent blood pressure control. Case 3, despite persistent high blood pressure during anesthesia, did not receive appropriate blood pressure control with antihypertensives. Appropriate management, including antihypertensive therapy for HDP, may reduce the risk of intracranial hemorrhage.
