Cervical Sympathetic Block in Patients With Cerebral Vasospasm
Cervical Sympathetic Block to Increase Cerebral Blood Flow in Patients With Cerebral Vasospasm Following Aneurysmal Subarachnoid Hemorrhage
Study Overview
Status
Intervention / Treatment
Detailed 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.

Experimental: Cervical sympathetic block
Patients hospitalized in the 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. |
All participants will get the cervical sympathetic block and catheter under ultrasound guidance.
