Forty six patients suffered from intracranial aneurysm complicated by postoperative vasospasm and delayed cerebral ischemia were monitored dynamically both by clinical observation of neurologic status and multiple items such as transcranial Doppler, serum osmolality, intracranial pressure and other somatic physiologic items related to monitoring. Patients were intensively and comprehensively treated according to individualized grading of vasospasm. Forty four patients (95.6%) were completely recovered from postoperative vasospasm and delayed cerebral ischemia, while 2 patients (4.3%) complicated by hemipalsy as a consequence of delayed cerebral ischemia. The occurrence of vasospasm and delayed cerebral ischemia, the criteria of TCD grading, the valuableness of multiple physiologic items and problems related to comprehensive treatment are discussed.
