OBJECTIVE: To report the effectiveness of intrathecal selective administration of urokinase infusion (ITSUKI) therapy delivered via a special kit (ITSUKit), developed to prevent vasospasm in patients with ruptured aneurysms who had undergone Guglielmi detachable coil (GDC) placement, in patients with World Federation of Neurological Surgery (WFNS) grade V subarachnoid hemorrhage (SAH). METHODS: A study of ITSUKI therapy with or without ventricular drainage enrolled 6 patients with WFNS grade V SAH owing to ruptured intracranial aneurysms who were eligible for coil embolization. The procedures were performed within 48 hours of the occurrence of aneurysmal SAH. The incidence of symptomatic vasospasm and the clinical outcomes based on the Glasgow Outcome Scale (GOS) were assessed at 6 months after SAH onset. RESULTS: All patients underwent complete coil embolization. There were no side effects or adverse reactions attributable to ITSUKI therapy. Symptomatic vasospasm occurred in one patient (16.7%). There were no patients with hydrocephalus. Based on the GOS, one patient had a good outcome, two manifested moderate disability, and three manifested severe disability. CONCLUSIONS: The results showed that the ITSUKit was useful for ITSUKI therapy. Although the combination of coil embolization and ITSUKI therapy did not completely eliminate WFNS grade V SAH, it significantly improved the treatment outcome in some patients.
