[An immediately post-operative death of a patient undergoing right external carotid artery-posterior cerebral artery bypass].

We experienced an immediately post-operative death due to rupture of a giant basilar aneurysm four hours after right external carotid artery-posterior cerebral artery bypass surgery. As we had had preanesthetic discussions with neurosurgeons repeatedly, they did not seek for a cause of the death on our anesthetic management. However, in general, not few surgeons believe that many postsurgical complications may be mainly due to anesthetic management but not to surgery as they believe that their surgical procedures are always faultless. Therefore, we should have a wealth of anesthetic knowledge to respond to any surgeon's questions regarding anesthetic management and to precisely explain a causal relation between postsurgical complications and anesthesia. In addition, we should have frequent discussions with surgeons on postsurgical management in sick patients. These may reduce misapprehensions of surgeons, patients and their family for anesthesia.
