PCI surgery alone requires doctors to discuss the manipulation of guide wires for a long time, and many of them are very complicated.
Okay, the next step is to feed the angiography catheter along the guide wire. Jin Tianyu, who asked his junior sister and junior brother to take his time, got started much faster by himself. One of his junior sisters and junior brothers promised to explore the path for him, and he roughly figured it out.
This patient's blood vessel condition means there is no need to waste time and we can speed up the treatment.
The catheter is delivered into place, and the end is connected to a syringe to withdraw and exhaust.
Connect the three-way three-way head and exhaust the air thoroughly to avoid air entering the coronary arteries and causing fatal air embolism.
During the exhaust process, the triple three-way head is connected to the baroreceptor, the contrast agent, and the normal saline or heparin for flushing. Among them, the baroreceptor is connected to the display instrument, and the operating doctor can observe the invasive pressure pattern of the aorta on the screen.
A normal pressure graph is a smooth wave with systolic pressure at the top and diastolic pressure at the bottom.
It is important to observe this during the entire coronary angiography process. Once the graphic changes into a V-shape, indicating that the catheter port is embedded in the coronary blood vessels, coronary spasm and blockage will occur, requiring emergency treatment.
The doctor checked that the patient's intraoperative indicators were normal and there was no risk overflow.
Prepare to turn on the camera for fluoroscopy.
Turn on the phone, the yellow light is on.
The image of the catheter in the coronary artery of the human body appears on the screen of the imaging machine. At the same time, the doctor can see the dark outline of the patient's heart, like a paper cut. The projection can be a static picture, and the connection can turn it into a dynamic movie picture, which will make the viewer feel a little bit
It's like watching a folk shadow play. The two-dimensional dynamic image of the heart can show the contraction and expansion of the heart, as lively as a naughty child. Plop, plop, the patient's heart beats on the plane, driving the coronary artery where the catheter is located.
Beating. The injected contrast agent travels with the blood in the artery. At this time, the doctor can clearly see the direction and diameter of the blood vessel with the help of the contrast agent. If the artery is narrowed and the blood cannot pass through the contrast agent, the blood vessel segment will be displayed.
The missing image here changes from black to white. This is coronary angiography.
Under fluoroscopy, the doctors repeatedly confirmed that the guide wire was in place, and then the guide wire and the angiography catheter were sequentially entered into the patient's left and right coronary arteries for angiography examination. As mentioned before, the X-ray system is a two-dimensional image and needs to be converted into a three-dimensional image.
It is necessary to conduct fluoroscopy on the patient's heart and blood vessels in multiple positions to collect all the information and input it into the computer to reconstruct the three-dimensional image, which means that the computer needs to be turned on to emit x-rays frequently.
"You guys get out." Jin Tianyu ordered the junior sisters and junior brothers to leave so that they would not be exposed to radiation.
Not wanting to cause any trouble to their senior brother, Xie Wanying and Pan Shihua accepted the command and exited the imaging machine room.
The nurse was waiting outside and helped them take off their surgical gowns and lead suits.
After taking off the lead clothes, the scrub clothes were covered with sweat. Xie Wanying and the others washed their hands, wiped away the sweat, and anxiously returned to the control room to see what would happen next.
The person who talked to Fu Xinheng on the phone changed from Dr. Xu to Dr. Shen.
"She helped, right?" Dr. Shen asked after hearing the progress of the matter, wondering if his "reckless" suggestion successfully reversed the situation.
Yu Xuexian wanted to tell this senior brother not to get angry.
"It shows that our Director Zhang has a very vicious vision." Dr. Shen laughed loudly, very happy with the result.
Doctors are happiest as long as their patients can be saved.
Dr. Xu leaned in front of the mobile phone and asked: "What's the status of the angiography now? Are the three blood vessels diseased?"
Definitely not. There was no such sign in the electrocardiogram done before.
