Early vascular consultation in the setting of oncologic resections: benefit for patients and a continuing source of...

Oncologic surgeons have become more aggressive at tumor resections that often require complex open vascular interventions. Vascular surgeons may be consulted preoperatively to aid in these cases, or commonly called into the operating room for an urgent consult. These operations provide a challenge to the vascular surgeon and also an opportunity for open vascular surgical training of residents. We present our experience with vascular surgical interventions during oncologic resections.

A retrospective review of a prospectively maintained vascular registry was performed to identify patients undergoing vascular surgery in the setting of oncologic resections. Tumor histology, location, type of vascular intervention, vascular, and oncologic outcomes were recorded and reviewed.

Over a 7-year period, 21 oncologic cases involving vascular surgeons were identified. Tumor types included sarcoma (9), adenocarcinoma (4), germ cell (4), paraganglioma (2), and others (2). Tumor locations included abdominal/pelvic (15), cervical (3), and extremity (3). Complete resection was achieved in 18 of the 19 patients; 2 patients underwent exploration alone for carcinomatosis. Vascular surgical procedures included bypass grafts in 7 patients, resection with primary repair in 5 patients, ligation/excision in 4 patients, and arterial mobilization in 3 patients. No major vascular complications occurred. Short-term patency rates were 100%. Survival rates following therapeutic resection were 90%, 80%, and 80% at 1, 3, and 5 years, respectively. Vascular surgeons were involved in the preoperative planning in 11 cases (52%). Patients with preoperative vascular consultation had significantly fewer vascular injuries, a nonsignificant trend toward lower blood loss, and a nonsignificant trend toward improved survival than those with urgent intraoperative vascular consultation.

Vascular interventions can lead to favorable long-term outcomes during definitive oncologic resection of diverse tumor histologies and locations. Vascular surgeons must be prepared to participate, frequently urgently, in oncologic procedures. Standard open techniques employing all aspects of vascular exposures continue to be integral to vascular surgery training. Preoperative consultation between the oncologic and vascular surgeons may lead to improved outcomes.
