I sat at the conference table, listening to both sides of the argument. The interventional radiologists presented their position, noting that they have been the exclusive providers of endovascular procedures in our region. Across from them, the young vascular surgeons respectfully countered that their training included endovascular procedures, and that they had every intention of performing them. The interventional radiologists rebutted, stating that in other institutions, a trend was developing in which their discipline was eventually completely losing this case volume to the vascular surgeons. They were losing what could be seen as a turf war.
