To determine the economic effect of endovascular therapy in conjunction with surgery for cerebral arteriovenous malformations.


Twenty-five patients with arteriovenous malformations treated with embolization and surgical excision or embolization alone were compared with reported results in 475 patients who underwent surgery only. Respective mean morbidity and mortality rates were calculated and a cost-effectiveness analysis was performed in terms of costs of hospitalization, professional fees, and other direct procedural and indirect costs. Quality-adjusted life-years saved were also calculated.


The net effective treatment cost per cure was $71 366 (in 1992 dollars) for embolization and surgery compared with $78 506 for surgery alone. This resulted in a 9% average savings per treated patient. Cost per quality-adjusted life-year calculations resulted in a cost of $6734 for embolization and surgery and $9814 for surgical treatment alone, with savings as high as 34% when endovascular therapy was used.


Endovascular therapy in conjunction with surgery resulted in significant economic benefits for treatment of cerebral arteriovenous malformations.
