Since one of the arteries of the brain is closed during an ischemic stroke, the essence of treatment is to restore blood flow through it, thereby starting the brain's work in full. It can be done effectively and quickly only surgically. There are two methods of treating a stroke.
1. Thromboextraction.
Special thrombo-extractor instruments (also called stent retrievers) are brought to the closed section of the artery under the control of X-ray surgical equipment. As a result, the thrombus remains on the retriever, it is pulled out of the artery along with it, and blood flow is instantly restored.
2. Aspiration.
In a similar way, a special catheter is introduced into the artery, a vacuum pump is turned on and thrombotic masses are aspirated (suctioned), thereby restoring blood flow. In complex cases, surgeons use various combinations of these two methods.
Today, it is possible to do without surgery if only small vessels of the brain are occluded (closed). What is popularly called a microstroke, that is, the focus of the lesion is small and requires medical correction.
The second pathology, which does not require surgical intervention, is popularly called a pre-stroke condition, and doctors call it a transient ischemic attack. A situation where there was a short-term disruption of the blood supply to a certain area of the brain with rapid recovery.
In all other cases, surgical intervention is definitely required.
