Evaluation Of The Intracranial Pressure Monitoring’s Clinical Value On Perioperation Of Intracranial Aneurysm

Object:To evaluate the clinical application of intracranial pressure (ICP) monitoring in the peri-operative period of intracranial aneurysm clipping.Methods:Eighty-eight patients undergoing continuous ICP monitoring following anterior intracranial aneurysm clipping surgery were enrolled in this study. The clinical data of initial Hunt-Hess scale, WFNS scale, Fisher scale, GCS,image features and long-term GOS was collected, and their correlations with ICP level were analysed retrospectively. Moreover, we reviewed five acute hydrocephalus patients following aSAH with external ventricular drainage (EVD) and intraventricular ICP monitoring, and related literatures were discussed.Result:ICP level was highly correlated with Hunt-Hess, WFNS, postoperative GCS, postoperative image and GOS. Whereas,13% of patients with clinical or radiological deterioration after surgery showed normal ICP level. For patients with poor Hunt-Hess, EVD and ICP monitoring failed to improve the clinical outcome.Conclusion:ICP monitoring provides benefit in the postoperative management of aSAH patients, while its occasional uncorrelation with clinical and radiological manifestation should be cautious. In acute hydrocephalus of aSAH, EVD is feasible. Stable ICP is essential in the EVD management of acute hydrocephalus to prevent rebleeding and infection.
