Identifying VTE&nbsp;&nbsp;risk factors is crucial for appropriate VTE prophylaxis measurements to&nbsp;<br> lower this complication following ABR.&nbsp;<br> <strong>Methods:</strong> Using American College of Surgeons National Surgery Quality Improvement Project database, we examined the clinical data of patients&nbsp;<br> who underwent ABR from 2016-2020 in the US. The frequency of VTE, day of occurrences and risk factors associated with VTE were evaluated.&nbsp;<br> <strong>Results</strong>: Overall, 11,847 patients underwent ABR in the study period. The overall VTE rate was 1.0%. Totally 117 patients experienced VTE with a&nbsp;<br> total occurrence of 127. Postoperative day 1 and 2 were reported with the highest frequency of VTE (21/127). Using multivariate regression analysis,&nbsp;<br> independent risk factors associated with a higher VTE rate were length of hospital stay>=5 d [adjusted odd&rsquo;s ratio (AOR), 3.29], operative time&nbsp;<br> longer than 10 h (AOR,2.17), and immediate reconstruction (AOR,1.51). Although free flap breast reconstruction was associate with a higher VTE&nbsp;<br> rate compared with pedicled flap reconstruction (1.2% vs. 0.8%); however, multivariate regressing analysis did not show this factor as an independent&nbsp;<br> VTE risk factor.<br> <strong>Conclusion:</strong> Being proactive to make the patients ready to discharge by POD-4 and having strategy to shorten the length of operation could help to&nbsp;<br> lower the rate of VTE in ABR. Plastic surgeons should consider these factors and use appropriate prophylactic measures to minimize the risk of VTE&nbsp;<br> development.</span></span> Risk factors, Venous thromboembolism, Autologous breast reconstruction 0 0 http://wjps.ir/browse.php?a_code=A-10-477-6&slc_lang=en&sid=1 Hossein Masoomi Hossein.Masoomi@kp.org 100319475328460017419 100319475328460017419 Yes Kaiser Permanente Bernard J.
