MINNEAPOLIS/ST. PAUL (May 28, 2009) While minimally invasive coil treatments for those with a ruptured brain aneurysm have proved to be a more effective technique than traditional surgical operation in selected patients, the superior procedure is drastically more expensive, according to new research from the Zeenat Qureshi Stroke Research Center at University of Minnesota Medical School.
Using outcomes from more than 2,000 patients half of whom underwent minimally invasive endovascular coiling for brain aneurysms and economic data gathered from a variety of hospitals throughout the United States, it is clear the minimally invasive procedure has better patient outcomes including qualify of life than the neurosurgical counterpart.
Minimally invasive treatments on average cost about $72,000 more than surgical treatments for each quality-adjusted life years gained (including costs stemming from disability, hospitalization, retreatment, and rebleeding) partly because multiple follow-up treatments are necessary within the first year of endovascular treatments, as opposed to one major surgical operation.
Coiling is a technique that involves placing a small catheter into the aneurysm and filling it with platinum coils. The catheter is introduced through a blood vessel in the groin and advanced under X-ray all the way into the brain blood vessels.
With accrual of additional years with better outcome status, the cost-effectiveness of endovascular coiling would most likely progressively improve and eventually reverse direction, said Alberto Maud, M.D., principal investigator of the study.
"The minimally invasive treatment is better tolerated in selected critically ill patients with ruptured brain aneurysms. The procedure is effective in preventing a second rupture but currently limited in terms of cost due to the need for additional follow-up procedures to treat new aneurysm growth," Maud said. "However, a new generation of devices promise
