Endovascular management of intracranial aneurysms during pregnancy in three cases and review of the literature.

We present three cases of cerebral aneurysms (1 unruptured; 2 ruptured) treated with endovascular techniques in pregnancies. The first ruptured case is a 28-year-old female on 20th gestational week. After the endovascular coiling, the patient suffered persistent hemiparesis and delivered a healthy baby by cesarean section. The second ruptured case is a 25-year-old female on 36th week of pregnancy. She died of aneurysm re-rupture after delivery of a healthy baby by cesarean section. The third unruptured case is a 31-year-old woman on the 26th gestational week of pregnancy who died of a giant basilar tip aneurysm after stent-assisted coiling. Ruptured aneurysm obliteration should be prioritized followed by vaginal delivery or cesarean section. The decision regarding the treatment of unruptured aneurysms should be carefully considered on a case-by-case basis. Stent-assisted coiling may be applicable to aneurysm during pregnancy.
