title: Clipping of cerebral aneurysm under hypothermic cardiac arrest and simultaneous coronary artery bypass grafting: case report.
abstract: This report describes a case where joint neurological and cardiac surgery teams cooperated to perform simultaneous procedures of clipping a complex internal carotid artery under hypothermic cardiac arrest and coronary artery bypass grafting. A 69 year old man was evaluated for complaints of double vision, pain behind his right eye, and progressively worsening headaches. Examination showed bilateral upgoing toes and difficulty performing a tandem gait. The patient had a history of myocardial infarction. Brain MRI showed a 1.6 cm diameter, partially thrombosed aneurysm of the right internal carotid artery and posterior communicating artery. Cardiac catheterisation showed critical coronary artery disease of the distal segment of the right coronary artery with 90% stenosis of the midcircumflex artery and an ejection fraction of 40%. After initial exposure of the aneurysm, the cardiac team instituted hypothermic cardiac arrest (21 degree C). The aneurysmal sac was collapsed and dissected from the surrounding perforators. An encircling fenestrated clip was applied and a small part of the neck of the aneurysm was further clipped with straight clips. The cardiac surgery team performed the coronary artery bypass grafting procedure. The patient recovered fully, returned to his normal activities, and is functioning independently.
