Abstract

BACKGROUND:

Cerebral vasospasm leading to delayed cerebral infarction (DCI) is a central source of poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Current treatments of cerebral vasospasm are insufficient. Cisternal blood clearance is a promising treatment option. However, a generally applicable, safe, and effective method to access the cisterns of the brain is lacking.

OBJECTIVE:

To report on stereotactic catheter ventriculocisternostomy (STX-VCS) as a method to access the cisterns of the brain for clearance of subarachnoid hemorrhage in patients with aSAH and coiled aneurysms.

METHODS:

In 9 aSAH patients at high risk for DCI (Hunt and Hess grade ≥3, modified Fisher grade ≥3), access to the basal cisterns of the brain was created by STX-VCS. Fibrinolytic and/or spasmolytic lavage therapy was administered.

RESULTS:

STX-VCS was feasible and safe in all patients. Subarachnoid blood was rapidly cleared by irrigation with urokinase. Vasospasm occurred in 2 patients and was interrupted by irrigation with nimodipine. There was 1 fatality due to pneumogenic sepsis. Minor DCI occurred in 1 patient. Eight survived without DCI and are independent (modified Rankin score [mRS] ≤ 3) at 6 mo after aSAH.

CONCLUSION:

STX-VCS allows for rapid clearance of subarachnoid hemorrhage in patients with coiled aneurysms.
