    Not only during puncture, if you are afraid of making mistakes, try to send the guide wire under fluoroscopy without inserting it blindly.  At this time, if the guide wire is sent to the wrong place, it can only be a special situation.

    Is there something blocked in the blood vessels?  Arterial occlusion usually occurs in the lower limbs and is unlikely to occur in the upper limbs.  The doctor will prescribe heparin and require double-antibodies for interventional surgery. What the doctor is more afraid of is massive bleeding during the transportation of the guide wire.  If the patient is nervous, vasospasm can also cause signs of guidewire jamming. For this reason, doctors routinely recommend verapamil and nitroglycerin, which can slightly alleviate such symptoms.

    The probability of the above two happening is low.  Jin Tianyu thinks so.  The reason can only go back to the possibility of the guidewire entering the branch incorrectly.  Whether the guide wire is on the wrong branch or not? It is not always possible to fully see the whole picture from a flat perspective.

    "How strong was the resistance when you sent it in? Is it very big?" Jin Tianyu asked Dr. Fang again to confirm whether the guide wire had entered the wrong branch just now.

    Everyone in the control room is listening to the answer.

    When the branch penetrates, the resistance will increase.  The diameter of the branches is smaller than that of the main trunk, and a skilled doctor can feel this subtle feeling.  Therefore, Dr. Fang¡¯s accurate answer is very important.

    Dr. Fang answered with difficulty while recalling: "I didn't feel a lot of resistance before. If there was, I definitely wouldn't dare to force it."

    Slowly and without encountering any major resistance along the way, it means you are on the right track.  How could it suddenly be wrong?  Doctor Fang couldn't understand.  The guide wire should have slid in along the large channel, so it would be an easy path.  Did the guidewire walk down the path on its own without the doctor forcing it?  Moreover, when he looked at the fluoroscopic images, it did not show that the guide wire had branched off.

    "How about you try it yourself." Dr. Fang couldn't figure it out, so he suggested to Jin Tianyu to try it himself to see if what he said was right.

    Jin Tianyu made no move, obviously he had to weigh the pros and cons.

    Dr. Fang has tried to get stuck in this place before. If he wants to try again, he must first find out the reason, otherwise it will be useless and only increase the risk.  I was lucky enough to have the guide wire withdrawn just now. If it gets stuck again, I may not be as lucky as before to successfully withdraw the guide wire.

    "Hanging." Li Chengyuan looked anxious at the people in the operating room who were not moving, and said to Fu Xinheng, "It's hard to say whether they have sent it to the brachial artery. It is more difficult to get to the axillary artery, subclavian artery, and aortic arch later."

    From the radial artery to the cardiac artery, the guidewire needs to pass through the brachial artery, axillary artery, subclavian artery, and then to the aortic arch to finally reach the bottom of the aortic sinus.  At this time, a contrast agent is created to identify the blocked coronary artery, 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 will be sent out from it, such as the deep brachial artery, the superior ulnar accessory artery, the inferior ulnar accessory artery, etc.

    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 in criss-cross directions, and each person¡¯s blood vessel map may be different.

    When doctors learn medical knowledge, they can only learn the common parts of the human body structure. Small differences can only be analyzed and controlled by clinicians based on individual cases.  It seems that the "abnormal" part of the blood vessel part of this case is extremely difficult for doctors to control at once.

    Emergency patients¡¯ time is their life. Doctors cannot ponder things slowly and must make decisions or make decisions as soon as possible.  (Remember the website address: www.hlnovel.com
