I Can See Health

   Chapter 831 I am an outsider

   The left main artery of the coronary artery is one of the most important blood vessels in the heart.

  Lu Chen also felt that the patient in front of him was very difficult.

   Recalling the training in the virtual space of the system, he began to feed the guide wire.

   "Bring 2 finger guide wires here!"

  When the guide wire slowly occludes the blood vessel, inject Xinweining and prourokinase immediately.

   "Another imaging!"

  Prourokinase is a thrombolytic drug.

  Intravascular thrombolysis can dissolve blood clots and reduce vascular stenosis.

   After repeated angiography, it was suggested that the proximal to middle segments of the left main trunk were severely calcified and the proximal segment was occluded!

   "Prepare for pre-expansion!"

  Lu Chen said in a deep voice.

   Before stent implantation, the blood vessel needs to be pre-dilated.

  He was sent 2 pre-expanded balloons to the lesion respectively.

   At this time, the mutation protrudes!

   Sudden restlessness, slow heart rate, and low blood pressure in a patient lying in bed.

   Bedside ECG prompts, frequent ventricular tachycardia.

   "Don't panic." Lu Chen calmly said, "It should be reperfusion injury!"

   "Hang a set of adrenaline!"

  The nurse acted immediately.

   Then, the patient's heart rate and blood pressure slowly began to rise.

"The patient has tortuous lesions and diffuse calcification, so the operation is too difficult!" said Jin Miao, the surgical assistant on the side, "Director, let's end the operation, I think the coronary blood flow has recovered, and wait until the patient wakes up. do it?"

   Implantation of stents in such severely calcified blood vessels can easily lead to stent malapposition and long-term stent thrombosis and stent stenosis.

   "Wait for the patient to wake up?" Lu Chen frowned, "Can he wake up without surgery?"

  Jin Miao was silent.

   "Use rotational atherectomy!" Lu Chen thought about it and said.

  Rotation atherectomy, referred to as rotational atherectomy.

   refers to the use of a rotor with ultra-high-speed rotation to grind the atherosclerotic plaque and calcified tissue in the coronary arteries into extremely fine particles, thereby eliminating the plaque in the blocked blood vessel lumen.

  The surgical nurse immediately brought over the rotational atherectomy machine.

  The top of the catheter for coronary atherectomy is a metal stainless steel drill head inlaid with fine diamond particles, which is in the shape of a spindle.

  When it rotates at high speed, it grinds the atheroma into fine debris and is flushed to the distal end, and the debris can pass through the capillary bed.

   "Director, the patient's vascular calcification is so heavy that with rotational atherectomy, in case the blood vessel is torn or dissected, it will be even more difficult!"

   Jin Miao reminded in a low voice.

   In his opinion, Lu Chen has done a good job of restoring the patient's blood flow and restoring the blood supply to the heart.

   Continue to sit, the risk will get higher and higher!

   Especially rotational atherectomy of the coronary intima.

Although    is a very good interventional technique, it is also very risky.

  The blood vessels of the human body are very fragile.

  High-speed rotational atherectomy can easily damage blood vessels.

   Coronary blood vessels were ruptured, torn, and dissection, which was another major blow to the patient!

   At this time, Lu Chen was extremely concentrated.

   He took the rotational ather bit and drilled it deep into the patient's blood vessels.

   Reaching the most important place for coronary calcification, he started the machine.

   Everyone present was sweating for Lu Chen.

   Especially the assistant Jin Miao, who was closest to Lu Chen.

Every movement of   Lu Chen touched his heart.

"continue!"

After    a calcified plaque, he did not stop.

  Only with one effort, can we survive a hundred battles!

   Lu Chen's confidence stemmed from his practice in the virtual space of the system.

   Even with systematic assistance, his training never stopped.

  From the initial electrophysiological surgery to the current TAVR surgery, Lu Chen has trained hundreds of times in the virtual space of the system for each type of surgery.

  …

  When the rotation of the rotational atherectomy diamond stopped, the people around looked at the surgical images in front of them, and they all took a breath of relief.

   This kind of rotational grinding technique, even Director Zuo Yaoqun has never had it?

  Jin Miao felt the deepest.

   As long as Lu Chen's hand trembles slightly, the patient's blood vessels may be injured!

   This risk is too high...

   But when the stent was successfully implanted into the blood vessel, the eyes of everyone looking at Lu Chen had already changed.

   Unexpectedly, Lu Chen's most powerful operation.

  It is not TAVR intervention, but coronary intervention!

   With Lu Chen's move today, Guanghai's coronary intervention pattern is likely to change!

   "Okay, finally done."

  4 stents were successfully implanted into the diseased blood vessels.

   Repeated angiography, blood flow returned to TIMI grade 3.

  Lu Chen took off his gloves and hat.

   Get out of the cath lab.

   Everyone greeted him.

   "Director Lu, you are really amazing!"

   "Director Lu, teach me about this rotational atherectomy just now!"

   "Don't think about it! Director Lu, I learn TAVR, I don't learn coronary artery!"

   For a time, everyone was chatting.

  Lu Chen raised his hand to signal everyone to be quiet.

   "Academic issues will be discussed later."

   "Today this patient is not over yet. Next, the patient needs to be taken care of after entering the CCU."

   A middle-aged doctor immediately patted his chest, "Director Lu, don't worry, I'm on duty tonight, and I'll put the patient in the emergency room in front of the office!"

   "Okay." Lu Chen smiled slightly.

   Then, he and Jin Miao came to the doctor-patient communication room.

  …

   "The operation was very successful." Jin Miao said, "4 stents were implanted, but whether the patient can wake up or not depends on the subsequent recovery."

   The eldest son of the patient heard this and thanked him.

   "Thank you Director Lu, thank you Doctor Jin."

  Lu Chen's tone was flat and he said slowly: "We did our best to do the surgery. The next care of the patient still needs the cooperation of the patient's family and our doctor."

   "Well, I understand, Director Lu." The man showed a smile, then checked to see if there was any surveillance nearby, quickly took out an envelope from his bag, and stuffed it into Lu Chen's arms.

   "This is our family's thanks to Director Lu. Just a small idea, please don't refuse."

  Lu Chen held a thick envelope in his hand and said slowly, "Don't tell me, our doctor is really short of money."

   "But we really can't ask for this money."

  Lu Chen handed the red envelope back.

   The patient's son thought it was a camera in the doctor-patient communication room, and quickly whispered, "Director Lu, let's go outside and talk later."

   "No need." Lu Chen waved his hand, "Actually... your family's biggest thanks to our doctor is trust!"

   After saying this, Lu Chen took a deep look at the patient and left first.

   Left the patient's family who frowned and thought deeply.

  …

   followed.

  Lu Chen informed Jin Miao and the CCU tube bed doctor about the precautions after surgery.

   He himself returned to the talent apartment.

  My parents are still at home waiting to have dinner together.

   Go home and open the door.

   There was a burst of laughter in the house.

  Lu Chen took a closer look.

  Xu Wei is chatting happily with Luo Meizhen.

   "Ah? Why are you here?" Lu Chen asked in surprise.

   Everyone turned their heads when they saw that Lu Chen was back.

   "You child, how did you talk?"

  Luo Meizhen glared fiercely at Lu Chen, "You don't welcome others to come to the house as guests?"

   "Mom, that's not what I meant." Lu Chen said helplessly.

  Xu Wei sat on the sofa, got up quickly and said, "Auntie, don't blame Lu Chen, he just came back from the hospital, he should be very tired."

  Luo Meizhen smiled and looked at Xu Wei, then pulled her to sit next to her.

   "Never mind them, let's talk more."

   Then, Luo Meizhen glanced at Lu Wenguo, "It's time for you to cook."

  Lu Wenguo could only put down the TV remote, but helplessly stood up and walked towards the kitchen.

  Lu Chen looked at Xu Wei and his mother who were chatting happily.

   felt like an outsider himself.

   "That...I'm going to help Dad cook."

  Luo Meizhen didn't even look at Lu Chen, she waved her hand, "Go."
