BXBX NOVEL Chapter 1384: 【1384】Hanging
Is there something blocked in the blood vessel? Arterial occlusion usually occurs in the lower extremities and is less likely to occur in the upper extremities. Doctors will push heparin, and double-antibodies should be used for interventional surgery. Doctors are more afraid of bleeding during guide wire delivery. If the patient is nervous, vasospasm can also cause signs of guide wire jamming. For this reason, doctors routinely push verapamil and nitroglycerin, which can alleviate such symptoms slightly.
The probability of both of the above happening is low. Jin Tianyu thinks so. The reason can only go back to the possibility of the guide wire going into the wrong branch. Whether the guide wire is in the wrong branch or not, the light from the plane perspective may not be able to fully see the whole picture.
"When you sent it in, how big was the resistance? Is it too big?" Jin Tianyu asked Dr. Fang again to determine if the guide wire had really gone wrong and entered the branch just now.
Everyone in the control room was listening to the answer.
penetrate the branch and the resistance will increase. The branches are smaller in diameter than the trunk, and skilled doctors can feel this delicate touch. Therefore, the accurate answer of Dr. Fang is very important.
Doctor Fang replied with difficulty while recalling: "I didn't feel a lot of resistance before, and if there were any, I would definitely not dare to force it."
Slowly delivered, no major resistance was encountered along the way, indicating that the route taken is the right one. How could it suddenly be wrong? Doctor Fang couldn't understand. This guide wire should have been slid in along the big passage, the way is easy. The guide wire walks the path by itself without the doctor's forced delivery? And he looked at the fluoroscopy and it didn't show that the guide wire went to the branch.
"Why don't you try it yourself." Doctor Fang couldn't figure out if he didn't understand, so he suggested to Jin Tianyu to try it himself to see if what he said was correct.
Jin Tianyu didn't move, obviously to weigh the pros and cons.
Dr. Fang tried to get stuck in this place before. If he wants to try again, he must first find out the reason, otherwise it will only increase the risk. Just luckily, the guide wire was withdrawn. If it gets stuck again, the guide wire may not be able to be successfully withdrawn as lucky as just now.
"Hang." Li Chengyuan looked anxious at the people in the operating room and said to Fu Xinheng, "It's hard to say whether they have been sent to the brachial artery. It will be more difficult to reach the axillary artery and the aortic arch of the subclavian artery later."
The guide wire from the radial artery to the cardiac artery needs to pass through the brachial artery, axillary artery, subclavian artery, and then the aortic arch and finally reach the bottom of the aortic sinus. At this time, a contrast agent is created to determine the blocked coronary artery segment, and a stent is placed if necessary.
The lower segment of the brachial artery is formed by the confluence of the ulnar artery and the radial artery. At the same time, it is an arterial trunk, which means that other blood vessels such as the deep brachial artery, the superior ulnar collateral artery and the inferior ulnar collateral artery will emerge from it.
The human cardiovascular system itself is an extremely complex and huge project, and blood vessels are an important part of the cardiovascular system. It is distributed throughout the human body and is staggered, and each person's blood vessel map may be different.
Doctors who learn medical knowledge can only learn the same part of human body structure, and small differences can only be analyzed and controlled by clinicians based on individual cases. Now the vascular part of this case seems to be extremely difficult for the "different" part, and it is difficult for doctors to control it all at once.
The time of emergency patients is life. Doctors can't think about it slowly. They must get it done or make a decision as soon as possible.
