急性脑卒中后下肢深静脉血栓形成的研究

Investigation of deep venous thrombosis of lower extremities after acute stroke

目的观察急性脑卒中后下肢深静脉血栓形成(DVT)的发病情况。方法对215例发病72h内的脑卒中住院患者于发病后4d及14d进行双下肢深静脉超声检测,确定下肢DVT的发生率。结果急性脑卒中下肢DVT的发病率为79%,卒中后4d即可出现,多数在发病14d后被检出。DVT主要影响患肢,也有部分病例累及双下肢。结论急性脑卒中患者早期即可出现下肢DVT,应尽早采取预防措施以降低其危害性。

ObjectiveTo observe the prevalence of deep venous thrombosis(DVT) of lower extremities after acute stroke. MethodsDetection by ultrasonogaphy of bilateral lower extremities was taken in inpatients with stroke within 72 hours 4 days and 14 days after stroke, in order to determine the morbidity of DVT. ResultsThe morbidity of DVT of lower extremities was 7.9%. DVT could be found 4 days after stroke, but the majority of cases were found out 14 days after stroke. DVT mainly affected the paralytic limb, but some of them could involve bilateral limbs.ConclusionDVT of lower extremities could develop at the early stage of stroke. It is necessary to utilize the prophylactic methods to reduce its harmfulness as early as possible. [
