Deep hypothermic circulatory arrest may prove advantageous during surgery of some technically difficult brain lesions. This technique was first applied in one patient with a large intracavernous aneurysm which had failed standard neurosurgical techniques. For this technique to be successful the cooperation of neurosurgeons, cardiovascular surgeons, anesthesiologists, perfusionists and nurses is essential. Techniques aimed at improving the outcome include a short period of circulatory arrest, the depth of hypothermia, barbiturate administration, coagulation management and well-controlled blood glucose levels. The total time of circulatory arrest and the thiopentone dosage were 61 minutes and 1,700 mg respectively. The lowest core temperature was 13.9 degrees C. The positive outcome supports the use of this technique in selected patients with complex intracranial vascular lesions who may not be operable by standard techniques.
