AB  - Background One of the primary device expenditures associated with the endovascular treatment of aneurysms is that of detachable coils. Analyzing the cost efficiency of detachable coils is difficult, given the differences in design, implantable volume, and the presence of additives. However, applying a volume per cost metric may provide an index analogous to unit price found in grocery stores.Methods The price information for 509 different coils belonging to 31 different coil lines, available as of September 2013, was obtained through the inventory management system at the study site, and normalized to the price of the least expensive coil. Values were used to calculate the logarithmic ratio of volume over cost.Results Operator choice among coil sizes can vary the material costs by five-fold in a hypothetical aneurysm.Conclusions The difference in coil costs as a function of cost per volume of coil can vary tremendously. Using the present pricing algorithms, using the longest available length at a particular helical dimension and system yields improved efficiency.
