First, let's look at how the stent is put into the cerebral blood vessels.
The whole blood vessels of the human body are the same as the sewer pipes in the city. If you enter from any wellhead, you can reach the place you want to go. So doctors, like cleaners, can deliver stents to the key parts of your brain through blood vessels as long as they choose the right position. Solve the problem? .
Generally speaking, the doctor will implant a channel (vascular sheath) in the aorta of the patient's limbs, and then use the delivery system to deliver the stent to the stenosis of the blood vessel through this channel. Femoral artery puncture is usually used for cerebrovascular stent.
Secondly, let's look at what material the bracket is made of. And about the stent? Personal?
1, the material used for support
Brackets are generally made of alloy, and certainly not ordinary alloy for doors and windows. These materials were screened by rigorous experiments before being used as scaffolds, including a series of studies on whether they can cause cancer, teratogenesis, rejection of blood vessels, biological toxicity and so on. Only by ensuring that these materials have no side effects can they be made into scaffolds for human body.
2. Is the imported bracket better than the domestic one?
At present, this problem no longer exists. The manufacturing technology and materials at home and abroad are the same, so there is no difference. Doctors only choose different modes according to the pathological changes. In addition, in the choice of bracket, is it imported or made in China? Doctors will also respect patients' opinions.
3. Does the bracket need to be replaced? Can you pass the plane security check?
If the operation is successful and the stent is not narrow, then it will become the most loyal one in your life? Partner? You have no reason to abandon it. As for flying, as long as it's not? Play big cards? You can fly unimpeded without insulting the security personnel like a star.
4. Is the bracket like this? Loyal and virtuous? Is it better to play more?
If you are not the emperor, forget about the three palaces and six hospitals. If you are not strengthened, don't ask for more. Installation? Brackets. The more parentheses, the better Stent implantation has strict standards. If it is multiple cerebrovascular stenosis, a variety of stents can be selected according to the specific situation. Under normal circumstances, the probability of implanting multiple stents in cerebral vessels is still relatively small.
Besides, the bracket? Loyalty? In addition, as long as the size is appropriate, the blood vessel itself has a repair function, and the stent will not fall off under normal circumstances.
Finally, what are the risks of intracranial stent implantation? Why is there still the possibility of hemiplegia after stent implantation with protective device?
Intracranial blood vessels are complex and tortuous, located in subarachnoid space, with thin blood vessel walls, which are very fragile and delicate. Toss? Yes So when the stent is opened, it is easy to cause blood vessels to rupture.
In fact, even if protective devices are used, it does not mean that cerebral embolism will not occur. The protection device only protects most emboli from running into normal blood vessels and causing cerebral embolism. Generally speaking, the protective device can only catch half of the fallen embolus. In addition, cerebral embolism may occur during and after surgery. So there is the possibility of hemiplegia.
In short, mature surgical techniques are risky. To maintain one's health, it is mainly to do preventive work, actively exercise, form good living habits, be healthy, and eat whatever one likes. This is the best life.
