急性脑梗死患者下肢深静脉血栓形成的危险因素及近期预后分析

目的研究急性脑梗死患者发生下肢深静脉血栓形成(LDVT)的相关危险因素,及其对患者近期预后的影响。方法分析2012年11月-2015年9月本院神经内科诊治的急性脑梗死患者536例,统计下肢深静脉血栓形成的发生率并探讨其危险因素,及其对患者近期预后的影响。结果急性脑梗死患者发生LDVT的比例为8.4%,经多因素Logistic回归分析,NIHSS评分、血D2聚体水平及糖尿病是急性脑梗死发生LDVT的危险因素。与非LDVT组相比,LDVT组的患者发病1个月之内死亡率高,差异有统计学意义(P0.05)。结论急性脑梗死患者发生LDVT概率较高,NIHSS评分及糖尿病是脑梗死合并LDVT的危险因素,而D2聚体对急性脑梗死患者合并LDVT存在一定预测价值。

Analysis of the associated risk factors of deep venous thrombosis in patients with acute ischemic stroke ;and its influence on the short-term prognosis

Objective To study the risk factors of deep venous thrombosis of lower limbs(LDVT) with acute ischemic stroke patients and the influence on the short-term prognosis. Methods We collected 536 cases of patients, who were diagnosed cerebral infarction, from November 2012 to September 2015 in department of neurology. To investigate the ratio of LDVT,analysis the associated risk factors and influence on short-term prognosis. Results This study result shows that, the rate of LDVT was 8.4%. the NIHSS score, D-dimer of blood, and diabetes were risk factors (P<0.05) of LDVT in acute ischemic stroke patients. Duration of hospitalization prolonged in LDVT groups and hospital costs increased. The mortality in patients of LDVT increased in a month after acute ischemic stroke. The differences were significant between the LDVT groups and non-LDVT group (P<0.05). Conclusion The rate of LDVT in acute ischemic stroke was higher. NIHSS score and diabetes were risk factors for LDVT. The D-dimer of blood with acute cerebral infarction has certain prediction value in the aspect of LDVT.
