Cervical sympathectomy to treat cerebral vasospasm: a scoping review
Authors' conclusion
This scoping review suggests that CSB may be a viable option for treatment and prevention of CAV/DCI in patients with aSAH, although the included studies were heterogeneous, mostly observational, and with a small sample size.
