Turf issues exist largely because of emerging endovascular technologies. Vascular surgeons must develop skills with catheters, guidewires, and imaging techniques. Turf battles will result from unrestrained competition. Center/partnerships between vascular surgeons and interventional radiologists will minimize these turf battles and facilitate cross-training, which will improve the functioning of both specialists. These center/partnerships will, therefore, provide the best, most cost-effective care. Finally, all specialists who are interested in vascular disease must recognize the dangers of overproduction of competing specialists. More importantly, their leaders and specialty societies must make a serious effort to deal with this problem fairly.
