Major vascular injury during gynecologic cancer surgery

Vascular injury during major gynecologic cancer surgery is a rare but potentially fatal complication. The purpose of this study was to review our experience with major vascular injury during gynecologic cancer surgery.

This was a retrospective chart review of women undergoing surgery by our gynecologic oncology department from 7/1/99 to 6/30/20 who had a major vascular injury. We identified women who sustained a vascular injury by a combination of CPT code and medical record searches, fellow case logs and a list maintained for an ongoing quality assurance program. Data were expressed as median and range for continuous variables and as frequency and percentage for categorical variables. Fisher's exact test was used to analyze differences in complication rates between groups.

Major vascular injury was identified in 52 patients and procedures. The inferior vena cava was the most common site of injury, 32.7% (17/52), followed by the external iliac vein, 23.1% (12/52). Lymph node dissection was the most common time for a vascular injury to occur 51.9% (27/52). The majority of injuries required suture repair, 80.8% (42/52). Estimated blood loss in cases with vascular injury ranged from 100 mL to massive unquantifiable blood loss in the case of an aortic injury. Patients required a median of 2units of packed red blood cells. Postoperative complications included anemia requiring blood transfusion, 19.6% (9/46) and venous thromboembolism, 19.6% (9/46).

Vascular injury remains a rare but potentially morbid complication of gynecologic oncologic surgery. Prompt recognition and management are imperative in minimizing persistent bleeding and complications.
