With the continuous development of science and technology, neurointerventional therapy has become an important means to treat stroke. Here, I will focus on the stent retriever, one of the devices used in neurointervention, and elaborate on its effectiveness in the treatment of stroke and its experimental evaluation.
First, we need to know what stent retriever is. The stent retriever is a metal mesh device that usually consists of a microguide wire and a delivery catheter. In neurointerventional surgery, it is mainly used to remove blood clots in brain vessels to restore blood flow. The stent retriever can hold a clot like a clip and "take it out" by rotating or pulling it. In addition, the stent retriever does not destroy blood vessel walls, which is not possible with other devices.
After years of practice and continuous technological innovation, stent retriever has become one of the standard devices for the treatment of acute ischemic stroke. The main principle is to "take out" the clot to restore blood flow while ensuring the protection of the blood vessel. So far, studies have shown endovascular clot retrieval devices to be highly effective.
Specifically, in 2015 the U.S. Food and Drug Administration (FDA) approved stent retriever device for use as a first-line treatment for acute ischemic stroke. In the same year, five large randomized clinical trials were launched worldwide examining the effectiveness of stent retrievval compared to device-free treatment. The results showed that in the stent retrieval interventional treatment group, the intensive endovascular therapy technique was slightly more effective than standard intravenous thrombolytic therapy and helped reduce patient mortality and disability.
In addition, the researchers evaluated the stent retrieval in a number of experiments in the lab. These evaluation tests will evaluate the stent retriever's ability to capture and control blood clots in detail to see if it can better restore blood flow. The stent retriever has demonstrated high reliability and accuracy in capturing blood clots of different sizes and shapes. The success rate of thrombectomy and the function of thrombolysis are higher than other instruments, and it has become an important force in the treatment of stroke.
Stent retrieval device is effective in the treatment of acute ischemic stroke. It uses a minimally invasive treatment that can both remove the clot and reduce the risk of bleeding. In addition, stent retriever is a treatment worthy of promotion due to its simple procedure and high safety.
In the future, we look forward to further development of stent retriever thrombectomy technology. The continuous innovation and innovation of neurointerventional therapy technology will not only meet the needs of a wider range of patients, but also improve the treatment effect and quality of life.
