Endovascular treatment of inferior vena cava syndrome / 中国微创外科杂志

ABSTRACT

Objective To investigate the curative effect of endovascular treatment for inferior vena cava syndrome(IVCS).Methods A total of 17 cases of inferior vena cava syndrome was treated by endovascular dilatation and self-expandable metallic stent placement between June 2002 and November 2004.Routine anticoagulation therapy was given after the procedure.Results The pressure gradient across the inferior vena cava was reduced from 16.8?4.3 mmHg preoperatively to 2.6?0.6 mmHg postoperatively(t=13.280,P=0.001).The IVCS symptom scores were decreased from 4.4?1.6 preoperatively to 2.1?1.7 postoperatively(t=6.880,P=0.010).Symptoms of edema on lower limbs,scrotal or pubic dropsy,ascites,and anasarca subsided at 1～4 days after procedure.Conclusions Endovascular treatment of inferior vena cava syndrome is effective and reliable.
