Postoperative central conduction time and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage: relationship with prognosis and ischemic conditions.
Cerebral blood flow (CBF) and somatosensory evoked potential (SEP) were monitored periodically on 32 patients who underwent aneurysm clipping within 3 days after subarachnoid hemorrhage (SAH). From the SEP data, central conduction time (CCT) was obtained, and CCT fluctuations were categorized into three types. Patients with CCT prolongation over 7.5 ms within 10 days after SAH tended to have poor recovery of CBF and unfavorable outcome. Therefore, periodical monitoring of CCT was considered as a useful indicator for predicting prognosis and post-SAH changes of cerebral blood flow.
