Research progress in mechanical thrombectomy device for deep venous thrombosis treatment / 国际生物医学工程杂志

ABSTRACT

Mechanical thrombectomy is a minimally invasive interventional method. Embolization device is too close to the blood vessel wall and venous valve in clinical applications, and it can cause blood vessel damage when it is sucked into the lumen. Embolization device is easy to cause hemolysis. Optimal design can reduce the damage to red blood cells, but it cannot be completely avoided; Shedding emboli can complicate the pulmonary artery. The clinical application studies of mechanical thrombectomy devices in the world was reviewed, including 74 experimental studies and 166 clinical application studies. The current status and causes of vascular injury, hemolysis and pulmonary embolism caused by mechanical thrombectomy were analyzed. This paper aims to make recommendations for the optimization of mechanical thrombectomy devices.
