Abstract

SUMMARY: Autologous breast reconstruction has evolved considerably from pedicled muscle-based approaches to microsurgical perforator-based techniques. Patients with documented coagulopathy, however, remain a particularly challenging population. The authors present their experience in microsurgical breast reconstruction in patients with coagulopathy and discuss their treatment protocol. A prospectively maintained database was queried for patients with coagulopathy who underwent microsurgical breast reconstruction between 2016 and 2019. Information regarding patient demographics, type of coagulopathy, and anticoagulation regimen were retrieved, and clinical outcomes were investigated. Nineteen patients who underwent 34 microsurgical breast reconstructions with free abdominal flaps were included in the study. The most common coagulopathy was factor V Leiden [n = 7 (38.6 percent)]. Nine patients (47.4 percent) developed thrombotic complications (the majority occurring intraoperatively); notably, arterial and venous thrombosis in four (21.1 percent) and two patients (10.5 percent), respectively. Postoperative thrombotic complications included pulmonary embolism [n = 2 (10.5 percent)] and flap congestion secondary to venous thrombosis [two flaps (5.9 percent)]. Only one flap loss was observed secondary to delayed venous thrombosis on postoperative day 6 (2.9 percent). The anticoagulation regimen in the majority of patients consisted of intraoperative intravenous administration of heparin (2000 U [bolus]) followed by a 5-day heparin infusion at 500 U/hour [n = 10 (52.6 percent)]. The high rate of thrombotic complications in patients with coagulopathy who underwent microsurgical breast reconstruction is contrasted by a low flap loss rate. Although coagulopathy is a risk factor for thrombotic complications, successful microsurgical breast reconstruction is still possible in the majority of patients.
