Change of serum D-D, sVCAM-1 and P-selectin after limb fractures surgery and their relationship with thrombosis / 中国医师杂志

ABSTRACT

Objective:To investigate the relationship between change of serum D-dimer (D-D), soluble vascular cell adhesion molecule 1 (sVCAM-1), P-selectin and thrombosis after limb fracture surgery.Methods:289 patients with limb fractures who were treated in the emergency department of Shulan (Hangzhou) Hospital from January 2021 to January 2022 were selected as the study subjects. They were divided into deep vein thrombosis (DVT) group ( n=62) and non-DVT group ( n=227) according to whether DVT occurred after operation. The levels of prothrombin time (PT), activated partial prothrombin time (APTT), D-D, sVCAM-1 and P-selectin were measured before and after operation in all patients. The levels of PT, APTT, D-D, sVCAM-1 and P-selectin were compared between DVT group and non-DVT group. Logistic sequential stepwise regression analysis was used to analyze the risk factors of postoperative thrombosis in patients with limb fractures. Results:There was no statistically significant difference in PT and APTT between 289 patients with limb fractures after operation and before operation (all P>0.05), while the levels of serum D-D, sVCAM-1 and P-selectin after operation were higher than that before operation (all P<0.05). There was no significant difference in general data between DVT group and non-DVT group (all P>0.05); There was no statistically significant difference in PT and APTT before and after operation between DVT group and non-DVT group (all P>0.05). The levels of serum D-D, sVCAM-1 and P-selectin before and after operation in DVT group were higher than those in non-DVT group (all P<0.05). Logistic sequential stepwise regression analysis showed that high levels of D-D, sVCAM-1 and P-selectin were risk factors for thrombosis after limb fracture surgery (all P<0.05). Conclusions:High levels of D-D, sVCAM-1 and P-selectin are risk factors for thrombosis after limb fracture surgery.
