Endovascular technology and its impact on the relationships among vascular surgeons, interventional radiologists, and other specialists.

Endovascular treatment methods that are largely catheter/guidewire-based permit treatment of a variety of vascular lesions from remote access sites in a minimally invasive manner. Because these endovascular technologies have intrinsic appeal to patients and physicians, they may, if proved safe and effective, replace a substantial proportion of current vascular surgical procedures. This change will have a substantial impact on the specialties involved in their development and use, that is, vascular surgery and interventional radiology (which in this discussion includes other interventional specialists devoted to peripheral vascular disease management). The relationship between these previously distinct specialties must also be influenced greatly by the introduction of endovascular technologies, the use of which requires skills that overlap the specialties. This paper considers several possible approaches for dealing with the altered interspecialty relationships that will result if new endovascular treatment methods prove to be safe and effective. Because the development and use of these endovascular technologies require the skills and talents of vascular surgeons and interventional radiologists (or other interventionalists), a collaborative, multispecialty approach to the use of endovascular technologies is recommended as the most reasonable and optimal for patient care. Although this approach may not be applicable for every environment, it is the one most likely to minimize costs and turf battles, particularly if interspecialty conflict can be minimized by collaboration and compromises developed by a conjoint executive committee representing the leadership of the involved specialty societies.
