Twenty cases of acute cerebral infarction complicated with deep venous thrombosis in lower limb

Objective To investigate the etiological factors, clinical characteristics, diagnosis and treatment of deep venous thrombosis in lower limb ( LDVT) in patients with acute cerebral infarction (CI).Methods Clinical datas of twenty cases of acute CI complicated with LDVT who were hospitalized in our department were analyzed retrospectively. Results Among these 20 cases, the percentage of patients over 65 years old was fifty - five. The percentages of patients with increased serum fibrinogen and hematocrit were sixty - five and forty - five respectively. The incidence rates of LDVT happened in palsy and normal limbs were 75% and 10% , respectively. The percentage of DVT in left lower limb was sixty, while that in right lower limb was twenty - five. The incidence rate of LDVT within one week after acute CI was the highest (55% ). Four cases with LDVT happened within three days received thrombolysis therapy by urokinase. Fourteen cases with LDVT happened in three to fourteen days received anticoagulant therapy by low molecular heparin. Healing rates between the two groups were not significantly different (75% vs 57% , P ＞0. 05). Conclusions Advanced age, hyperviscosity, paralysis and anatomic factors are all the major reasons of LDVT in acute CI. Thrombolysis and anticoagulant therapies are both effective for LDVT. Prevention and early treatment of LDVT in acute CI have great significances. Key words: Acute cerebral infarction;  Deep venous thrombosis in lower limb
