Multiple interventional models combined via anterior tibial veins in treatment of acute deep venous thrombosis / 中国介入影像与治疗学

ABSTRACT

Objective To explore the efficacy of multiple interventional models combined through anterior tibial veins approach in treatment of acute deep venous thrombosis (DVT).Methods The clinical data and the imaging materials of 10 patients with acute DVT were analyzed retrospectively,and the interventional treatment strategies were discussed.Results The percutaneous mechanical thrombectomy (PMT) was performed after a temporary inferior vena cava filter implanted in all patients,and thrombus clearance rate of grade Ⅲ was obtained in 7 patients while 3 patients reached grade Ⅱ criteria.There were 7 patients underwent angioplasty,then the inferior vena cava filter was retrieved during the same procedure in 5 patients while 4 patients in the second stage and 1 patient rejected to retrieve the filter.All swelling limbs alleviated significantly after those procedures.There was no critical complications occured.The total hospital stay ranged from 4 to 7 days,with a mean time of (6.00±0.94) days.All patients were followed up with a mean time of (3.60± 1.84) months (ranged from 1 to 6 months).No thrombus recurrences of the previously affected vessels were reported.Conclusion The multiple interventional models combined via anterior tibial veins for acute DVT is simple,safe and effective,combined with mechanical thrombectomy device can reduce thrombus burden quickly,and combined with angioplasty can consolidate the therapeutic effect,all those methods combined can shorten the overall hospitalization time.
