When encountering resistance during extubation, the thrombus adsorbed on the catheter tip may fall off after encountering resistance from the guide catheter tip. When encountering resistance during extubation, we should carefully find out the reasons and avoid rough operation to avoid complications such as coronary artery dissection. The most common reason is that the guide wire is bent or twisted at the opening of catheter and coronary artery.
Thrombosis aspiration catheter
Thrombosis aspiration catheter is a medical instrument used to treat intravascular thrombosis. It can directly aspirate thrombus through intravascular intervention to prevent thrombus migration or re-formation. The device can be widely used for the treatment of cardiovascular and cerebrovascular diseases, deep vein thrombosis and other diseases.
Thrombosis aspiration catheter usually consists of two parts: catheter and aspiration system. Catheters are generally made of soft and elastic materials, which can pierce a patient's vein or artery. The suction system is the part connecting the catheter with the outside world, through which the pressure generated at the catheter end can be guided out of the body, so as to realize the suction operation of thrombus.
When using thrombus aspiration catheter, drugs such as heparin saline should be added at the same time to reduce the formation of thrombus fragments and blood coagulation. In the whole process, we need to pay attention to factors such as attraction direction, attraction speed and attraction time.
With the continuous development of medical technology, more and more domestic thrombus aspiration catheters gradually appear. Among them, Harmony China intracranial thrombus aspiration catheter system Afentta is the first intracranial thrombus aspiration catheter system in China, which has more advantages in technological innovation. The appearance of these domestic thrombus aspiration catheters can not only meet the needs of the domestic market, but also improve China's technical level in this field and gradually open the era of import substitution.
