Background: Vascular surgeons are sometimes called on to complete an ongoing surgical procedure or to repair an intraoperative vascular injury by other surgical specialists. We have analyzed our experiences in these cases. Methods: Since 1992, 28 patients in other departments were operated jointly with vascular surgeons. Six patients were operated in the gynecology department, 3 in urology, 1 in pediatric surgery, 1 in otology, 1 in orthopedics, and 16 in general surgery. The procedures were repair of intraoperative vascular injury, repair or extraanatomic bypass for infuse-a-port complication, and concomitant vascular resection and reconstruction with neoplasm removal. Results: Postoperative morbidity and mortality were acceptable except for the cases complicated with infected infuse-a-port. Especially in the patients with malignancies, the extended operations were safely performed and an improvement of quality of life was obtained. However, long-term survival could not be obtained, except for the patients with renal cell carcinoma. Conclusion: The conditions for calling on vascular surgeons for assistance in the operations at other department were divided in repair of the intraoperative vascular injury, delayed vascular complication of the catheter treatment, and concomitant vascular resection and reconstruction in neoplasm removal. Vascular complication with infection had a poor outcome. Although extended operation for the malignancies with concomitant vascular resection could be performed with acceptable morbidity and mortality, such operations could be justified only in cases of renal cell carcinoma, in terms of long-term survival.
