At present, peripheral vascular diseases have been carried out artificial vascular diversion, abdominal aortic aneurysm surgery, arteriotomy and thrombectomy, femoral arterioplasty and other surgeries, and the application of interventional minimally invasive treatment technology, maturely carried out the lower extremity atherosclerotic occlusion, diabetic foot lesions vascular balloon dilatation, stenting and stent implantation, and with the combination of traditional surgery, the vascular surgery has been successfully carried out the “hybridization of technology Combined with traditional surgery, it has successfully carried out the “hybridization technology” of vascular surgery, which has improved the level of clinical treatment. He has mastered the techniques of inferior vena cava filter placement and temporary filter retrieval. It has effectively avoided the risk of fatal pulmonary embolism (PE) for nearly 100 patients with lower extremity deep vein thrombosis. The application of this technology provides strong support for the comprehensive treatment of lower extremity DVT in our department (surgical thrombus extraction, interventional thrombus fragmentation, interventional catheter drug thrombolysis, stent recanalization, etc.), so that DVT can be treated more effectively and ideally. Our vascular surgery technology has reached the advanced level in our city.
