    The technique of manipulating the guidewire alone in PCI surgery is enough for doctors to discuss for a long time, many of which are very complicated.

    Okay, the next step is to advance the contrast catheter along the guide wire.  Jin Tianyu, who asked his junior sister and junior brother to take their time, got started much faster.  A junior sister and junior brother had promised to help him explore the road. He had a rough idea of ??the patient's blood vessels and could speed up without wasting time.

    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, contrast agent, and 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.

    The normal pressure graph is a smooth wave with systolic pressure at the top and diastolic pressure at the bottom.

    It is very important to observe this during the entire coronary angiography process. Once the graphic changes into a V-shape, indicating that the catheter port is entangled 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.

    Ready to turn on the camera for fluoroscopy.

    Turn on the phone and the yellow light is on.

    An image of the catheter in the human coronary artery appeared on the screen of the imaging machine. At the same time, the doctor could see the dark outline of the patient's heart, like a paper cut.  The photos can be static pictures, and when connected, they become dynamic movie images. The viewer will feel a bit like watching a folk shadow puppet show.  The two-dimensional dynamic image of the heart can show the contraction and expansion of the heart, which is as lively as a naughty child.  Thump thump, the patient's heart beats on the plane, causing the coronary artery where the catheter is located to beat together.  The injected contrast agent travels with the blood in the arteries, and the doctor can clearly see the direction and diameter of the blood vessels with the help of the contrast agent.  If the artery is narrowed and the contrast agent cannot pass through the blood, the missing image in the blood vessel segment will appear to change 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. To turn it into a three-dimensional image, it is necessary to conduct fluoroscopy on the patient's heart and blood vessels in multiple positions, collect all the information, and input it into the computer for the computer to reconstruct the three-dimensional image. This is equivalent to turning on the computer and emitting x-rays frequently.  light.

    "You guys get out." Jin Tianyu ordered his junior sisters and junior brothers to leave so that they would not be exposed to radiation.

    Not wanting to cause any trouble to the senior brother, Xie Wanying and Pan Shihua accepted the command and exited the imaging machine room.

    The nurse was waiting outside to help 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 their 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 be embarrassed.

    "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.  (Remember the website address: www.hlnovel.com
