Early Lumbar Drainage Plus Intrathecal Urokinase in Severe Aneurysmal Subarachnoid Hemorrhage (LD-ITUK)

The LD-ITUK is a multicenter, prospective, randomized, double-blind, blind endpoint, placebo-control design trial. All eligible patients with the diagnosis of severe aSAH will be randomly assigned to the treatment group or the placebo group. Patients in the treatment group will receive standard treatment with the addition of lumbar drainage combined with intrathecal urokinase injection started within 24 hours after aneurysm treatment with 30000 IU urokinase, once a day for 3 consecutive days. Patients in the control group will receive standard treatment with the addition of lumbar drainage combined with intrathecal placebo (0.9%NaCl) injection. The primary outcome measure is favorable functional outcome, defined as a score of 0 to 2 on the modified Rankin Scale (mRS), at 6 months after aneurysmal SAH. Primary outcome will be determined by a member of the Independent Committee on Terminal events.
