SaExten vena cava filter

Denali inferior vena cava filter

Arm Description

Manufacturer: ShenZhen KYD BioTech Co., Ltd., China. SaExten vena cava filter system is a retrievable filter system consisting of two parts: the vena cava filter and the delivering system. The vena cava filter is a mesh filtering device that prevents the formation of pulmonary embolism by filtering the thrombus. The SaExten vena cava filter can be inserted through jugular or femoral veins, and can be retrieved through jugular vein within 90 days or indwelled in vena cava permanently.

Manufacturer: C. R. BARD, Inc., USA

Outcomes

Primary Outcome Measures

Clinical success requires the following three factors: No clinical symptomatic pulmonary embolism occurred within 6 months after long-term filter implantation, which was confirmed by CT pulmonary angiography (CTPA); No clinical pulmonary embolism occurred between the time of filter implantation and the time of filter retrieval, which was confirmed by pulmonary angiography. The IVCF was successfully implanted with satisfactory shape and position; No filter fracture, no displacement over 20 mm , no inclination (> 15°) during implantation/retrieval, no IVC penetration, no thrombosis of the IVC, and no implant-related or operation-related deaths.

Secondary Outcome Measures

Clinical success of filter recovery is defined as: The filter was successfully and completely removed from patients attempting to retrieve the filter within 90 days of filter implantation, without complications requiring clinical intervention.
Technical success rate of IVCF retrieval
Successful filter retrieval is defined as: the filter was successfully and completely removed in patients who attempted to retrieve the filter within 90 days after implantation, and no complications associated with the filter occured during the operation.
Evaluation of operation performance of filter and transporting system
Technical success of the filter and transporting system is defined as: during the operation, the marking and development of the transporting system were good, the filter was transported to the expected position of the vena cava smoothly, the preloaded filter was released completely, and all parts of the transporting system were removed from the body smoothly without falling off or breaking.
The combined incidence of filter displacement over 20 mm, fracture, tilt (> 15°) and IVC penetration within 6 months after implantation
These measures are used to describe the incidences of filter post-implantation.
Incidence of pulmonary embolism within 6 months after implantation.
It is used to describe the incidence of PE post-implantation.
The incidence of new or aggravated deep vein thrombosis within 6 months after implantation
It is used to describe the incidence of DVT post-implantation.
The incidence of compound clinical events of pulmonary embolism, IVC thrombosis, death, and recurrent deep venous thrombosis of lower limbs at 30 days, 3 months, and 6 months after vena cava filter implantation
These measures are used to describe the incidence of PE, IVC thrombosis, death, and and recurrent DVT post-implantation.
