Safety and Feasibility of Femoral Vein Thrombectomy for Deep Vein Thrombosis in the Lower Limbs / 中国微创外科杂志

ABSTRACT

Objective To investigate the safety and feasibility of femoral vein thrombectomy for patients with acute deep vein thrombosis in the lower limbs.Methods During June 2003 to August 2006,a succession of 43 patients with acute deep vein thrombosis in the lower extremities received femoral vein thrombectomy in our hospital.An inferior vena cava filter was employed before the operation.Anticoagulation and regional thrombolysis were taken postoperatively.Analyse the data of operation procedure,curative effect and complications.Results The operation time ranged from 55 to 115 minutes with a mean of 92.6 minutes.Four of the patients received blood transfusion during the operation.The mean blood loss was 384.6 ml (100 to 1000 ml).Five patients showed transient fluctuation of blood pressure during the surgery.None of the patients had pulmonary embolism during and after the operation. Five patients developed lymph leakage from the incision at the inguinal area,and was cured in 1 week.One aged patient suffered from postoperative postatic pneumonia and was cured before being discharged;no other complications were found in this series.The thrombectomy achieved good outcomes in our patients.The edema and pain in the lower limbs were relieved quickly after the operation, the difference between the circumferences of the two legs decreaed from a median of 5.5 cm (thigh) and 4.0 cm (crus) to 1.5 cm and 1.0 cm (Z=-5.345,P=0.000 and Z=-5.461,P=0.000),respectively,32 of the patients received re-examination 6 months postoperation,none of them showed recurrent thrombosis.Conclusions Femoral vein thrombectomy is feasible and safe for serious acute deep vein thrombosis in the iliac and femoral veins.Patients can recover quickly after the operation.
