As a minimally invasive technique, vena cava filter implantation index has become one of the preferred treatment methods for VTE patients. Nowadays, interventional radiology has become the third largest clinical diagnosis and treatment means after medical treatment and surgical treatment, and is widely used in clinic. Pulmonary embolism is the most serious complication of deep venous thrombosis of lower limbs, and inferior vena cava filter is one of the most effective prevention methods. What is the vena cava filter for? Generally speaking, vena cava filter is an instrument used to prevent pulmonary embolism caused by deep venous thrombosis of lower limbs falling off and returning to the heart. This article will introduce the history of inferior vena cava filter.

Introduction of VTE

Venous thromboembolism (VTE) includes deep venous thrombosis DVT and pulmonary embolism (PTE). DVT and PTE are the manifestations of VTE in different stages and parts. The reflux of human lower limb venous blood mainly depends on the function of leg muscle pump, which promotes the lower limb blood to flow back to the heart through the contraction of leg muscles and the one-way valve opening and closing of venous valves. When the activity of the lower limbs is reduced or braked due to various reasons, the blood flow will slow down, and the blood of the lower limbs will gather to form thrombus, which is clinically called "DVT". After deep venous thrombosis of lower limbs, the new thrombus easily leaves the venous wall, enters the right ventricle along with the blood flow, and the right ventricle contracts, pushing it into the pulmonary artery, resulting in a series of symptoms and even sudden death, which is clinically called pulmonary embolism PE.

Umbrella-shaped removable filter

The Unique Umbrella Shape vena cava filter can be used for acute VTE or to prevent fatal PE, and the period of filter protection is several weeks (usually 2 weeks) to several months. (1)Günther Tulip Filter(GTF): it is the earliest umbrella-shaped removable filter used clinically, and can be inserted through bilateral femoral veins or internal jugular veins. Take out the time window. Most literatures report it for weeks to months. (2) Elect: it is the updated product of GTF, and its insertion and removal ways are the same as GTF's. The withdrawal time window of Celect is longer than that of GTF. In a prospective, multi-center registration study, the average withdrawal time was 179 d[36] [36]. (3)Denali: It can be inserted through bilateral femoral veins and internal jugular vein/subclavian vein [37-39]. The outer packaging box of femoral vein approach is purple, and that of internal jugular vein/subclavian vein approach is blue. In a prospective, multicenter study, the average removal time was 200.8 days. (4)Option: the insertion route is the same as other umbrella-shaped removable filters. In a multicenter study, the average removal time was 67.1 days.
