老年痴呆合并脑卒中后偏瘫患者深静脉血栓发生的危险因素分析OA

Objective:To explore the retrospective risk factors for deep venous thrombosis(DVT)in elderly patients with dementia complicated by post-stroke hemiplegia.Compare the stroke-related indicators,treatment and nursing factors,and laboratory parameters between the two groups,and perform multivariate analysis to identify the risk and protective factors for DVT.Compare the stroke-related indicators,treatment and nursing factors,and laboratory parameters between the two groups,and perform multivariate analysis to identify the risk and protective factors for DVT.Methods:A retrospective analysis was conducted on 100 elderly patients with dementia and post-stroke hemiplegia who visited our hospital from January 2024 to August 2025.They were divided into a thrombosis group(n=40)and a non-thrombosis group(n=60)based on whether they developed DVT.The general characteristics,stroke-related indicators,treatment and nursing factors,and laboratory indicators between the two groups were compared.Multivariate analysis was performed to identify risk and protective factors for DVT.Results:zStroke severity,severe paralysis,prolonged bed rest,diuretic use,elevated D-dimer,high FIB,and shortened PT/APTT were independent risk factors for DVT.Early rehabilitation and prophylactic anticoagulation were significant independent protective factors(P<0.05).Conclusions:The occurrence of DVT in elderly patients with dementia complicated by post-stroke hemiplegia is closely associated with multiple factors.Severe stroke,profound paralysis,prolonged bed rest,diuretic use,elevated D-dimer,high fibrinogen,and shortened PT/APTT are independent risk factors for DVT,while early rehabilitation and prophylactic anticoagulation represent significant independent protective factors.
