Abstract
We reported a case of true posterior communicating artery (Pcom) aneurysm, which was treated surgically after recanalization of Guglielmi Detachable Coils (GDC)embolization. A 51 year-old woman suffered sudden headache, and was admitted to our hospital immediately after onset. She had no neurological deficit apart from the headache (H-K grade I ). CT scans demonstrated a subarachnoid hemorrhage in the basal cisterns and right sylvian fissure. Cerebral angiography revealed a globular aneurysm with clear neck, arising from the right Pcom. An emergency GDC embolization was performed 6 hours after onset, resulting in almost complete occlusion of aneurysm. She was discharged on foot with mild feeling of weakness of the right upper and lower limbs. Follow-up angiogram obtained seven months later revealed recanalization and changes in the shape of the aneurysm. One year and five months later, neck clipping of the aneurysm via the right frontotemporal route was successfully performed. It was suggested that further GDC treatment or a surgical approach should be considered when follow-up angiogram revealed recanalization and changes in the shape of the aneurysm.
