The study suggests that perioperative venous thromboembolism risk is not significant among transgender and gender nonbinary patients undergoing gender-affirming surgery, regardless of whether estrogen hormone therapy is suspended before surgery.
Background: Both surgery and exogenous estrogen use are associated with increased risk of venous thromboembolism (VTE). However, it is not known whether estrogen hormone therapy (HT) exacerbates the surgery-associated risk among transgender and gender nonbinary (TGNB) individuals. The lack of published data has contributed to heterogeneity in perioperative protocols regarding estrogen HT administration for TGNB patients undergoing gender-affirming surgery. Methods: A single-center retrospective chart review was performed on all TGNB patients who underwent gender-affirming surgery between November 2015 and August 2019. Surgery type, preoperative HT regimen, perioperative HT regimen, VTE prophylaxis management, outcomes, and demographic data were recorded. Results: A total of 919 TGNB patients underwent 1858 surgical procedures representing 1396 unique cases, of which 407 cases were transfeminine patients undergoing primary vaginoplasty. Of the latter, 190 cases were performed with estrogen suspended for 1 week prior to surgery, and 212 cases were performed with HT continued throughout. Of all cases, 1 patient presented with VTE, from the cohort of transfeminine patients whose estrogen HT was suspended prior to surgery. No VTE events were noted among those who continued HT. Mean postoperative follow-up was 285 days. Conclusions: Perioperative VTE was not a significant risk in a large, homogenously treated cohort of TGNB patients independent of whether HT was suspended or not prior to surgery.
