Preoperative Heparin For Lung Cancer Resection Increases Risk Of Reoperation For Bleeding.
Seminars in Thoracic and Cardiovascular Surgery(2020)
摘要
Lung cancer patients are at risk for venous thromboembolism (VTE). Preoperative heparin administration may increase the risk of bleeding requiring reoperation. The purpose of this study was to evaluate preoperative heparin's effect on reoperation for bleeding. A retrospective review compared outcomes for patients undergoing pulmonary resection for primary lung cancer from January 2006-April 2018. Preoperative heparin was administered at the discretion of the attending surgeon. Comparisons were performed between preoperative subcutaneous heparin (5000 U) and no heparin groups. 3,325 lung resections were reviewed, 1.4% (n=48) required reoperation for bleeding. VTE occurred in 1.1% (n=38). 464 patients (14.0%) did not receive preoperative heparin. The preoperative heparin group had increased rates of prior thoracic surgery (5.1% [n=146] vs. 1.7% [n=8], p<0.001), minimally invasive approach (40.2% [n=1150] vs. 10.6% [n=49], p<0.001), and sublobar resections (17.7% [n=506] vs. 10.6% [n=49], p<0.001). There were no differences in blood loss/transfusions. Reoperation for bleeding was significantly increased in the preoperative heparin group (1.6% [n=47] vs. 0.2% [n=1], p=0.017). There were no differences in VTE (1.5% [n=7] vs. 1.1% [n=31], p=0.424). On logistic regression, preoperative heparin was independently associated with increased reoperation for bleeding (OR 8.13, p=0.039), however preoperative heparin was not independently associated with VTE. Preoperative heparin was associated with increased reoperation for bleeding. VTE rates are low after pulmonary resection for lung cancer and are not decreased by preoperative heparin. Preoperative heparin use should be determined by risk factor stratification for VTE and reoperation for bleeding in patients undergoing lung cancer resection.
