Randomized Controlled Trial Multicenter Study
Analysis of cost related to clinical and angiographic outcomes of aneurysm patients enrolled in the international subarachnoid aneurysm trial in a North American setting.
The goal of this study was to compare, in a North American setting, the cost-effectiveness of neurosurgical clipping versus endovascular coiling treatment of ruptured intracranial aneurysms. A secondary goal was to assess the clinical outcomes of patients enrolled into the International Subarachnoid Aneurysm Trial (ISAT) from the largest contributing North American center. ⋯ The high procedure costs of endovascular coiling tended to offset apparent reductions in length of stay. Long-term follow-up is indicated both for costs incurred after initial treatment and for clinical outcome in patients with incompletely obliterated aneurysms.
