Intraaneurysmal GDC Embolization for Ruptured Aneurysm in the Acute Stage. Indication and Results.
This report focused on our treatment protcol and results on the intraaneurysmal GDC embolization for ruptured aneurysm in the acute stage. Clinical materials of this study consist of 39 patients who were treated with intraaneurysmal GDC embolization within 72 hours after the onset of subarachnoid hemorrhage from March 1997 to May 1999. Patients with cerebral aneurysms are always examined as a possible candidate for neurosurgical clipping. If the patient had any difficulties and/or problems on neurosurgical clipping (high age 24, poor grade 12, surgically difficult location 11, systemic disease 2), the patient was treated by intraaneurysmal GDC embolization. GDCs were inserted as tight as possible. Then, spinal drainage was set in patients with thick subarachnoid hemorrhage. Tissue plasminogen activator was administered via the drainage in patients with thicker subarachnoid hemorrhage. Two patients experienced rerupture during peritherapeutic period. Symptomatic vasospasm was observed in 2 patients (5.1%). Good outcome was obtained in 31 out of 34 surviving patients. Symptomatic complication caused by distal embolism occurred in 1 patient, parent artey occlusion in 3 patients. In conclusion, intraaneurysmal GDC embolization is thought to be sufficient regarding prevention of rerupture, incidence of vasospasm, and clinical outcome.
