Abstract:
Objective:To explore the causes of acute lower extremity deep vein thrombosis（DVT）with pelvic malignant tumors and their experience in endovascular treatment in patients.Methods:The clinical data of 32 patients with pelvic malignant tumor complicated with acute DVT of lower extremities,treated by the catheter-induced thrombolysis（CDT）and balloon dilatation or stenting (iliac vein stenosis ≥50%) from January 2009 to March 2015 were analyzed retrospectively.Results:The vena cava filters (VCF) were placed before CDT in all patients,thrombolysis time was (5.3±2.6) d,urokinase dosage (320±130) million U.The average patency rate was (83.7±16.9)% after CDT.Of 32 cases,only 3 cases presented mild bleeding during thrombolysis,and stopped bleeding after adjustment of medication.13 cases of iliac vein stenosis ≥ 50% received stenting who were implanted in 17 stents,11 cases of iliac vein stenosis between 30% to 49% only PTA,8 cases of iliac vein stenosis <30% without balloon dilatation and stent implantation.During treatment,asymptomatic pulmonary embolism (PE) occurs.Thirty patients were followed up for (13.6±5.4) months.During the follow-up time,DVT recurrence occurred in 6 cases,including 1 case of stent,4 cases of the iliac vein stenosis in 30% to 49%,1 case of the iliac vein stenosis ＜30%,which were again CDT combined with PTA and Stent treatment success.Conclusion:Pelvic malignant tumor and radiotherapy are the risk factors which could led to lower extremity DVT and thrombosis recurrence.Intravascular interventional therapy is a positive and effective treatment.When iliac vein stenosis is more than 30%,we believe that stent implantation should be done.
