Abstrakt: Background: Autologous breast reconstruction is considered high-risk for deep vein thrombosis (DVT) and thromboembolism (PE). It is therefore recommended to treat patients undergoing these complex and lengthy procedures with DVT chemoprophylaxis. The optimal anticoagulation protocol is still not established. The objective of our study was to evaluate the need of a prolonged anticoagulation in patients undergoing microsurgical breast reconstruction.
Methods: This retrospective cohort study compares our former anticoagulation protocol, which was given during the in-hospital stay, with our new protocol consisting of extended anticoagulation until postoperative day 25, in terms of DVT/PE risk reduction. A logistic regression was used to evaluate the risk of DVT/PE between the two groups, while adjusting for several covariates.
Results: Our cohort consisted of 205 patients in the short-term anticoagulation group and 219 in the extended protocol group. Five patients (2.4%) in the short-term anticoagulation group had a DVT/PE event versus 4 patients (1.8%) in the extended protocol group. Logistic regression revealed no difference in the incidence of DVT/PE between the two groups. Similarly, there was no differences in terms of hematoma and infection rate between the two groups. Finally, we found an increased risk of DVT/PE in patients with a Caprini score equal or greater than 8.
Conclusion: In our experience, short-term anticoagulation during the hospital stay is equivalent to extended thromboprophylaxis in terms of DVT/PE prevention.
