[Latest cognition of treatment on deep vein thrombosis of lower extremity].

Objective: To explore the effects of surgical procedure combined with the intravascular minimal invasive technique for the treatment of deep vein thrombosis (DVT) of lower extremity.

Methods: At the curse of disease from six hours to ninety days, one hundred and two patients with DVT including one hundred and three lower extremities had received surgical procedure and intravascular minimal invasive treatment.

Results: There were not procedure-related morbidities in 102 cases, and symptoms disappeared, all procedures were successful based on angiography. The detecting head for the intravascular ultrasound ablation was entered to inferior vena cava (IVC) in 74 cases (78%), Forgarty catheter was entered to IVC in 21 cases (21%), the stenosis in the confluence of the common iliac vein and IVC was dilated by sacculus rotundus catheter in 89 cases (88%), including 9 patients underwent percutaneous transluminal stenting. One hundred and two patients followed up for twenty months, follow-up by angiography showed no restenosis in 91 cases, restenosis in ilio-femoral vein in 1 cases, and thrombus recontouring in 4 cases, as well as 6 cases died caused by primary disease.

Conclusion: Surgical procedure combined with the intravascular minimal invasive technique is a safe and effective therapeutic method for DVT.
