P19: THE RELIABILITY OF VENOUS THROMBOEMBOLISM RISK ASSESSMENT TOOLS FOLLOWING FREE FLAP RECONSTRUCTION OF THE LOWER EXTREMITIES

Abstract Introduction The incidence of flap failure in lower extremity reconstruction is significantly higher the compared head, neck and breast reconstruction. commonest cause venous thrombosis. aim this study was to assess reliability VTE risk assessment tools patients with open fractures ability such identify at developing microvascular thrombosis following free Method A single centre retrospective cohort conducted between August 2012-August 2019. All were assessed using Department Health (DoH), Modified Caprini Padua tools. Result 58 included, all high DVT according DoH (mean score± SD, 3.7±0.93), (10.2±1.64) (5.4±0.86) received thromboprophylaxis, clinical deep 0%. Intraclass correlation coefficient demonstrated moderate agreement (0.73, 95% CI 0.54-0.84, p<0.001), (0.52, 0.19-0.72, p<0.001) (0.74, 0.57-0.85, p<0.001). Microvascular occurred 6 patients, resulting 2 amputations. There no significant differences scores those without complications. Conclusion Current do not complications Further prospective studies are required optimise prediction models thromboprophylaxis use cohort. Take-home message limb
