Abstract
Hypothermia and circulatory arrest is efficatious adjunct in the surgical treatment of conventionally difficult or otherwise inoperable lesion. This technique was utilized in 5 patients, 3 with membraneous obstruction of inferior vena cava[MOVC] and 1 with giant middle cerebral artery aneurysm and 1 with renal cell carcinoma invading inferior vena cava. All membraneous obstruction of inferior vena cava patients had excellent results but the others died of operative complications. The rationale for the use of complete cardiac arrest with hypothermia is reviewed and the use of these technique in selected patients is warrented.
