Treatment of bilateral mycotic intracavernous carotid aneurysms. Case report.

A case of bilateral mycotic intracavernous carotid aneurysms is reported. Because of progressive bilateral ophthalmoplegia, the internal carotid artery (ICA) was ligated on both sides, combined with bilateral extracranial-intracranial arterial bypass. A superficial temporal artery-middle cerebral artery anastomosis was performed first on the right side followed by ligation of the right ICA at the neck. After an interval of 20 days, a bypass and ICA ligation was carried out on the left side. The patient developed mild hemiparesis and dysphasia during and immediately after the second operation, but these neurological deficits disappeared after elevation of systemic blood pressure.
