PCI surgery alone is enough to allow doctors to discuss it for a long time, many very complicated things.
Okay, the next step is to send the angiography catheter along the guidewire. Jin Tianyu, who asked his junior sister to take his time, was much faster to get started. After making a promise to explore the way for him, he roughly understood the patient's blood vessel condition and did not waste time to speed up.
The catheter is sent in place, the tail end is connected to the syringe to withdraw and exhaust.
Connect the triple tee head and exhaust thoroughly to prevent air from entering the coronary artery and causing fatal air embolism.
During the exhaust, the triple tee is connected to the pressure receptor, contrast agent, and the normal saline or heparin of the flush tube. Among them, the pressure receptor is connected to the display instrument, and the operator can observe the invasive pressure pattern of the aorta from the screen.
The normal pressure pattern is smooth waves, with the apex being systolic pressure and the valley bottom being diastolic pressure.
It is important to observe this during the entire coronary angiography process. Once the graph changes into a V-shaped shape, it shows that the catheter orifice is embedded in the coronary blood vessels, coronary spasm and blockage will occur, which requires emergency treatment.
The doctor checked that the patient had normal intraoperative indicators and no risk of overflow.
Prepare to turn on the computer for perspective.
Turn on the computer and the yellow light is on.
The picture of the catheter in the human coronary artery appears on the screen of the contrast machine. At the same time, the doctor can see the patient's dark heart profile, as if paper-cut. The projected can be a static picture, which is connected to become a dynamic movie picture, and the viewer will feel a bit like watching a folk shadow puppet. The two-dimensional dynamic image of the heart can show the heart's contraction and expansion, and it is as lively as a naughty child. The puff, the patient's heart beats on the plane, causing the coronary artery where the catheter is located to beat. The injected contrast agent is accompanied by the blood in the artery. The doctor can clearly see the direction and diameter of the blood vessels with the help of the contrast agent. If the artery is stenosis, the blood cannot pass through the contrast agent, and the missing image in the blood vessel section will be shown to turn from black to white. This is coronary angiography.
Under fluoroscopy, the doctors repeatedly confirmed that the guide wire was not in place. Then the guide ribbon and the angiography catheter should enter the patient's left and right coronary arteries in turn for angiography. As mentioned earlier, the x-ray system is a two-dimensional diagram. To become a three-dimensional diagram, it is necessary to conduct multiple positions on the patient's heart and blood vessels to collect all information and enter it into the computer for the computer to reconstruct the three-dimensional image, which is equivalent to emitting x-rays frequently during the computer turning on.
"You guys go out." Jin Tianyu ordered his junior sister to leave and prevent them from experiencing radiation.
Without causing trouble for the senior brother, Xie Wanying and Pan Shihua were instructed to withdraw from the angiography room.
The nurse was waiting outside and helped them take off their surgical gowns and lead gowns.
After taking off the lead clothes, the sweat on the brushed clothes was covered with sweat. Xie Wanying and the others washed their hands, wiped the sweat casually, and rushed back to the control room to see what happened next.
The person who was on the phone with Fu Xinheng changed from Dr. Xu to Dr. Shen.
"It was her who helped me, right?" Dr. Shen asked after hearing the progress of the matter, wondering if his "reckless" suggestion had successfully turned the situation around.
Yu Xuexian wanted to tell this senior brother not to be proud.
"It means that our Director Zhang's vision is very toxic." Dr. Shen laughed loudly, very happy with the result.
Doctors are happiest to see patients being saved.
Dr. Xu leaned in front of his cell phone and asked, "What is the situation with the imaging now? Are the three lesions changing?"
