Gynecologic surgery has potential for adjunct vascular interventions, given the proximity of major intra-abdominal and pelvic blood vessels. Our goal was to determine contemporary incidence, associations, and outcomes of vascular repairs in gynecologic operations. The American College of Surgeons National Surgical Quality Improvement Program database (2005-2017) was queried for patients undergoing elective gynecologic operations. Vascular repairs were performed concurrently or during reoperation. Univariable and multivariable analyses evaluated associations with vascular repairs and 30-day morbidity. A total of 201,224 gynecologic operations were identified: hysterectomy (88.3%), myomectomy (5.9%), adnexal surgery (3.5%), vulvovaginectomy/other (1.1%), nonadnexal tumor or cyst excision (0.5%), ectopic pregnancy treatment (0.4%), and pelvic lymphadenectomy (0.3%). There were 187 vascular repairs in 176 (0.09%) patients. Repairs were typically concurrent (89.8%) and most commonly included open abdominal blood vessel repair (51.8%), major abdominal artery ligation (25%), vena cava reconstruction/ligation (6%), common iliac vein ligation (4.2%), and aorta/great vessel repair (4.2%). A minority were performed endovascularly (1.7%). Patients undergoing vascular repairs were older (56 vs 46 years), were more likely to have an open vs minimally invasive/vaginal operation (71.6% vs 28.4%), and were more likely to have a hysterectomy (85.2%; P < .001 for all). In multivariable analysis, vascular repairs were observed more often with hysterectomy (odds ratio [OR]; 7.63, 95% confidence interval [CI], 2.28-25.55; P = .001) and open vs minimally invasive/vaginal operations (OR, 5.24; 95% CI, 2.64-10.42; P < .001). Vascular repairs were also more common for patients with malignant disease (OR, 2.84; 95% CI, 1.78-4.53; P < .001), patients assigned to American Society of Anesthesiologists class 3 or class 4 (OR, 1.85; CI, 1.36-2.53; P = .002), and patients without obesity (OR, 1.45; 95% CI, 1.08-1.96; P = .014). Vascular repairs independently predicted major morbidity and mortality (OR, 7.26; 95% CI, 5.26-10.03; P < .001) after adjustment for open operative approach, American Society of Anesthesiologists class 3 or class 4, and hysterectomy. Whereas vascular repairs during gynecologic operations are rare, they are associated with morbidity and mortality. These findings provide an evidence base for risk assessment and informed consent.
