Abstract:
Objective To study the long-term result of thrombectomy and thrombolysis for acute mixed deep vein thrombosis(DVT)of the lower extremity. Methods Clinical data of 142 patients treated for acute mixed DVT from September,1991 to June,2005 were reviewed.There were 77 patients treated by thrombectomy.Among these 77 patients there were 49 patients whose common iliac vein was occluded or stenosis.All the 77 patients received territorial transfusion with urokinase and hepafin after operation.The other 65 cases were treated by systemic thrombolysis with urokinase and heparin. Results Two weeks after thrombectomy or thrombolysis,the circumference difference between bilateral limbs was occlusive from (4.3±2.2)cm to(0.6±0.5)cm in thrombectomy group,and from(3.9±2.5)cm to(1.6±0.9)cmin thrombolysis group(t=-8.346,P=0.000).Patients were followed up for an average of(49±42)months.The circumference difference between bilateral limbs was reduced to(0.5±0.4)cm in thrombectomy group and(1.4±1.3)cm in thrombolysis group respectively(t=-5.764,P=0.000).The sequela morbidity in thrombectomy group was less than that in thrombolysis group(P＜0.05).The morbidity of edema,pigmentation,and ulcer was 29.9%,15.6%,0%in thrombectomy group and 50.8%,84.6%,6.2%in thrombolysis group.In thrombectomy group,89.6%veins regained patency and 72.7%valves had normal function compared with that in thrombolysis group 30.8%and 9.2%(Z=-8.502.P=0.000).The cure rate was 70.1%in thrombectomy group and 30.8%in thrombolysis group (Z=-4.740.P=0.000).Mortality rate was 3.9%in thrombectomy group,while there was no inhospital death in thrombolysis group. Conclusions For the treatment of acute mixed DVT.especially in protecting the normal valve function,thrombectomy was significantly superior to that of thrombolysis except for causing some mortality.
