Anesthetic approach of pregnant woman with cerebral arteriovenous malformation and subarachnoid hemorrhage during pregnancy: case report.

Abstract

BACKGROUND AND OBJECTIVES:

Subarachnoid hemorrhage (SAH) during pregnancy is a rare event, and about half the cases are due to arteriovenous malformations (AVM). The authors describe the anesthetic approach of a 39 week pregnant patient scheduled for cesarean section, with a history of SAH due to AVM at 22 week gestation.

CASE REPORT:

39 week pregnant patient, healthy prior to pregnancy, with a history of SAH at 22 week gestation, manifested by headache, vomiting, and dizziness without loss of consciousness or other deficits on admission to the emergency room. Magnetic resonance imaging (MRI) revealed a left frontal AVM. After a short hospital stay for stabilization and diagnosis, the fi nal medical decision was to maintain the pregnancy and a multidisciplinary follow-up by neurosurgery and high-risk obstetric consultation. An elective cesarean section was performed at 39 weeks under epidural anesthesia. During the intraoperative period, an episode of hypotension rapidly reversed with phenylephrine occurred. The newborn Apgar score was 10/10. An epidural catheter was used for postoperative analgesia, also uneventful.

CONCLUSIONS:

There are very few published cases of anesthetic approach for pregnant women with symptomatic AVM. All decisions made by the multidisciplinary team, from choosing to continue the pregnancy to the ideal time for AVM intervention and type of anesthesia and analgesia, were weighted according to the risk of brain damage. Regarding the anesthetic procedure, the authors emphasize the need for hemodynamic stability.
