Subarachnoid Hemorrhage from Posterior Cerebral Artery Aneurysm during Puerperium – Case Report and Review of Literature

Abstract

Subarachnoid hemorrhages (SAH) due to true aneurysms of the Posterior Cerebral Artery (PCA) during puerperium in young and healthy females are extremely rare.
We present the case of a 31-year old, healthy woman that experienced a spontaneous SAH due to a PCA aneurysm, arising from the P3 segment, 9 days post-delivery. The aneurysm was successfully treated via an endovascular approach and the patient recovered well. After 21 days she was discharged from hospital without neurological deficits. The clinical course is described in detail and illustrated with a computed tomography scan (CT) and digital subtraction angiography (DSA) pre – and post-embolization.
The literature is reviewed and possible etiologies of the formation and rupture of the aneurysm are discussed.
