ABSTRACT

Objective To evaluate the effect of ultrasound ablation transluminally(USATL) for deep venous thrombosis(DVT) of lower extremities. Methods The clinical features of 47 patients with DVT of lower extremities treated by USATL were retrospectively analyzed. Results 5 cases were changed to surger because of a long disease course(4 months～4 years) or chronic inflammation.42 cases had satisfactory results with USATL.Among them,36 cases restored to complete return venous flow;6 had partial return flow. The symptoms and signs of 42 cases were alleviated apparently compared with pretreatment.1 case died of the rectal cancer metastasis 2 months after the treatment.Conclusions USATL can ablate DVT safely ,effectively, and conveniently.Some other transluminal angioplasties are necessary to improve the therapeutic result.
