Kissing aneurysms of the internal carotid artery

Abstract

Kissing aneurysms (KAs) are rare and cause various problems when clipping of these aneurysms is attempted because they often partially adhere to each other. A 65-year-old female presented with subarachnoid haemorrhage due to a ruptured aneurysm originating from the left internal carotid artery (ICA)-posterior communicating artery A. She also had an unruptured aneurysm arising from the bifurcation of a left ICA-anterior choroidal artery A. Intraoperative findings revealed that these were KAs. Surgical clipping was performed. The postoperative period was uneventful. In this case report, we would like to stress the rarity of KAs and the difficulty in the diagnosis and management of such cases.
