To assess the risk of developing deep vein thrombosis (DVT) after inguinal hernia surgery, and to provide corresponding countermeasures for different risk levels.

A retrospective analysis was conducted on patients undergoing surgery for inguinal hernia in Shengjing Hospital from March 2015 to January 2018. The risk scores were assessed by the Caprini Thrombosis Risk Assessment Scale into four groups: low-risk, intermediate-risk, high-risk, and extremely high-risk. Each group was divided into anticoagulation group and non-anticoagulant group according to whether anticoagulation treatment was performed after operation. The number of DVT patients after inguinal hernia was counted, and the results were statistically analyzed by chi-square test.

A total of 72 patients with low-and intermediate-risk grades did not develop DVT after operation; 369 patients were in the extremely high-risk class, 7 patients developed DVT in the anticoagulation group, and 15 patients in the non-anticoagulation group, the difference was not statistically significant (χ²=20.379, P<0.05); 113 patients with high-risk grade, 3 patients with DVT in anticoagulation group, and 7 patients with DVT in non-anticoagulation group, The above differences were statistically significant (χ²=5.744, P<0.05). Patients with intermediate-risk level, the difference was not statistically significant(P>0.05).

Reasonable prevention and treatment according to risk classification after inguinal hernia can reduce the risk of postoperative DVT.
