Summary

This trial will assess if a cervical sympathetic block can improve cerebral blood flow & neurological function in people with aneurysm-related brain issues.

Who is the study for?
This trial is for adults over 18 who are in the ICU with cerebral vasospasm following a brain aneurysm bleed. It's not suitable for those with advanced kidney disease.
What is being tested?
The study tests whether a cervical sympathetic block, which is an injection near the neck to interrupt nerve signals, can improve blood flow in the brain and neurological recovery after a subarachnoid hemorrhage.
What are the potential side effects?
Potential side effects of cervical sympathetic block may include soreness or bruising at the injection site, temporary difficulty swallowing, hoarseness, and less commonly, drooping eyelid or pupil constriction.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Cervical sympathetic blockExperimental Treatment1 Intervention
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.
