The occluder is a retractable umbrella-shaped stent, the umbrella is made of nickel-iron alloy dense interwoven, and there is a waist in the middle of the double umbrella.
During the procedure, a hole is punched from the medial thigh blood vessel to deliver a catheter to the atrial chamber of the heart, and then the catheter has been contracted in the double umbrella, arriving at the designated location, such as an atrial septal defect, the catheter enters from the right atrium, the catheter mouth is between the position of the mouth of the defect, just probing into the left atrium, at this time, releasing the first umbrella, so that the waist is stuck in the interatrial septum, slowly pumping the catheter back to push the second umbrella to exit the catheter and release. In this way the atrial septum is occluded.
The blocker can stay with the patient for the rest of his or her life, with very few problems. After recovering from surgery, many people are as healthy as they are, and it doesn't affect their life expectancy; for example, in the case of a 22-year-old boy, he can easily go play basketball without the slightest discomfort. Still, patients need to care a little about themselves and not get too sloppy.
It is more difficult for young children to undergo occlusion surgery than it is for adults. Young children's circulatory blood vessels are too short and their blood flow is too rapid, making the catheter or occluder subject to a great deal of resistance; and young children's tolerance is too low.
Before the surgery, the nurse shaved her thighs to prepare the skin for the operation. At that time, the nurse was the first time to operate, very shy. I was also a little embarrassed, heart, he is a nurse, this is the work, I am the patient, this is the treatment. Let's get started! Except for the skin preparation, nothing happened. I'm not going to be able to do that.
I was awake at the time of the surgery. 3-4 doctors, first of all, local anesthesia was applied to the root of the right thigh, which only felt like ants stinging a few times, and I could not feel my thighs.
Then, the vein (or artery) was found and perforated, passed to the tube, the blocker was delivered and blocked. In the meantime, I felt the catheter enter my heart, and my heart choked, as if it was literally jumping into my throat, and there were about 3-4 times this feeling, each time as if I was going to die.
Finally, the end of the blockage, wrapped some bandages around the base of the thighs, and then the blood vessels bleeding holes, pressed a very heavy salt bag, used to stop the bleeding. The doctor instructed the body to lie flat for 24 hours, do not drink water, do not move, the salt bag must be pressed in that position, the stool can only endure, urinate lying down to solve. This time, I also learned such a high level of action.
24 hours, I lie flat and do not move, feel wooden, during which, urinate three times, twice. The first time, it was a bun bought by my brother, and the second time, it was a banana.
After 24 hours, the salt bag was removed and I was able to get off the floor; after seven days I left the hospital and was able to work.
After that, I took aspirin for a long time.
Now, I'm fine.
