Splenic artery aneurysm rupture in a pregnant woman with hepatosplenic schistosomiasis: case report and literature review

Pregnancy is not uncommon in patients with non-cirrhotic portal hypertension. Rupture of a splenic artery aneurysm remains a rare complication, associated with a very poor maternal–fetal prognosis. Our aim is to report a case of ruptured splenic aneurysm and to show the maternal–fetal over-risks during the association of pregnancy and portal hypertension, even in non-cirrhotic patients.

We report a case of a 34-year-old woman, pregnant at 24 weeks gestation, with non-cirrhotic portal hypertension due to hepatic schistosomiasis. She was hospitalized for variceal bleeding. Patient had undergone endoscopic variceal band ligation and no bleeding recurrence. An unexplained hypovolemic shock appeared during the hospitalization with the occurrence of an in utero fetal death. The fetus was delivered by vaginal delivery. Abdominal CT scan angiogram showed a splenic artery aneurysm rupture. The patient underwent an emergency laparotomy with ligation of the splenic artery associated with splenectomy. Postoperative course was simple. Management of portal hypertension was continued at discharge (diuretic, beta-blockers, and esophageal varices ligation).

The association of pregnancy and portal hypertension remains a serious situation with a high risk of maternal–fetal complications. Splenic artery aneurysm rupture is one of the rare complications of this association with a very poor maternal–fetal prognosis. Open repair is the surgical treatment of choice with a non-negligible morbi-mortality.
