Abstract

A true posterior communicating artery (pcomA) aneurysm (AN) is rare. We describe our experience of clipping an unruptured true pcomA AN and discuss the indications for and points to consider during surgery.

The patient, a 76-year-old man, was referred to our department after a magnetic resonance imaging incidentally revealed a left internal carotid-posterior communicating artery AN. Angiography, performed to obtain detailed information about the neck of the AN showed that it arose from the pcomA immediately after the bifurcation of the internal carotid artery. The cerebral AN was 5 mm in length and directed laterally. Surgery was performed using a left pterional approach. The anterior choroidal artery, which was in contact with the dome of the AN, was dissected, clipping was performed, and the perforating branch of the pcomA on the dorsal side of the AN was confirmed. Postoperative 3D-computed tomography angiography confirmed complete clipping, and the patient was discharged without any neurological deficits.

Since small ANs may rupture in true PcomA AN, aggressive surgical treatment should be considered even for small unruptured ANs. Furthermore, the wall of the AN may be fragile; therefore, extreme care should be taken during the surgery.
