Background Despite guideline-compliant prophylaxis, an increased rate of deep venous thrombosis (DVT) formation has been reported following autologous versus implant-based breast reconstruction. We hypothesized that tight abdominal fascia closure might decrease lower extremity venous return and promote venous stasis. Methods An observational crossover study of patients who underwent autologous breast reconstruction using transverse rectus abdominis musculocutaneous/deep inferior epigastric artery perforator flaps was conducted. Ultrasonographic measurements of the left common femoral vein (CFV) and right internal jugular vein (IJV) were performed preoperatively, in the postanesthesia care unit, and on postoperative day (POD) 1. Parameters of interest included vessel diameter, circumference, area, and maximum flow velocity. Results Eighteen patients with a mean age and body mass index of 52.7 years (range, 29-76 years) and 31.3 kg/m(2) (range, 21.9-43.4 kg/m(2)) were included, respectively. A 29.8% increase in CFV diameter was observed on POD 1 (p?
