Cervical Sympathetic Block in Patients With Cerebral Vasospasm

Status Enrolling by invitation

Clinical Trial Summary

The purposes of this study are twofold: 1) to assess the effect of a cervical sympathetic block on cerebral blood flow in patients suffering from cerebral vasospasm, after aneurysmal subarachnoid hemorrhage; 2) to evaluate the effect of the sympathetic block on the recovery of the neurological function.

Clinical Trial Description

Patients hospitalized in the intensive care unit (ICU) and developing clinical manifestations of cerebral vasospasm will undergo a computerized tomography (CT) angiography and a CT perfusion scan. If the vasospasm will be confirmed by the CT imaging, a cervical sympathetic nerve block under ultrasound guidance will be performed. The block consists in the deposition of local anesthetic at the cervical sympathetic ganglion that will be visualized with an ultrasound device. A periganglionar catheter will be left in place. A CT angiography and CT perfusion will be repeated to check the effect of the block on the brain vasculature after the block is done. Patients will have a daily monitoring of their neurological function and of their cerebral blood flow with transcranial doppler in the ICU. ;
