Inclusion criteria
Inclusion criteria: 1. Subjects aged 18-75 years old; 2. Patients with any of the following conditions (one of the following is sufficient) (1) Percutaneous mechanical thrombus removal (PMT) or thrombectomy is required for acute DVT (2) Other intravenously operated procedures identified by the researchers as having a high risk of PE: for example, when the filter was recovered, it was found that the filter blocked a large number of thrombus, or deep vein thrombosis combined with iliac vein stenosis/occlusion required intravenously treated with balloon dilation and stent implantation 3. The subjects can understand the purpose of the experiment, voluntarily participate in and sign the informed consent, and are willing to complete the follow-up according to the requirements of the project; 4. The investigators determined that there was a suitable vascular approach; 5. Diameter of inferior vena cava =28mm.
