Chapter 407 The Vine Exits the Heart. Oops, It Didn’t Exit!

Chapter 407 The vine exits the heart—oh, it didn’t exit!

"What? What's stuck in the heart?"

The Necromancer hurriedly poked his head over, eyes widening as hard as he could, but couldn't see anything. Miss Yinlong lowered her voice and whispered:

"[Detect Magic]! See for yourself!"

"ah……!"

Leon let out a low exclamation. In the meditation field of view, among the thick and light shadows, a long line snakes like a snake, rising from the junction of the rabbit's right leg and torso, all the way to the heart.

Gretel squinted his eyes and looked at the vine inserted into the rabbit's heart in his meditation field of vision, filled with emotion.

In the two years since he left Heartland City, he has not forgotten that cabin, Uncle Karen who took care of him when he was growing up, and Aunt Eileen who stayed up all night to change his clothes.

Moreover, he will never forget little sister Avril Lavigne, who suffered from patent ductus arteriosus, was born weak, and had cyanosis on her fingernails.

When he boarded Archmage Carlisle's airship and flew to the parliament headquarters, he secretly said to himself——

Give me eight years. Sister Avril has ten years at most, so eight years, preferably within five years, I want to find a way to safely perform interventional surgery!

To achieve this goal, staying in Heartland City and immersing yourself in running a small clinic will not work. It's not enough to stay in Nevis City and immerse yourself in experiments in the Mage Tower. To improve the level of a mage, you need to practice both magic and divine arts, you need to develop medical magic and medicine at the same time, and you need to have enough patients...

Two years of hard work, two years of study. From a first-level mage to a fourth-level mage, Grete has already gone through half the journey of interventional treatment:

Ultrasound magic, done!

Penicillin research and development, completed!

Chloramphenicol, streptomycin, tetracycline and other antibiotics are under development!

The vine birthing technique is completed, and a wave of proficiency has been refreshed on the dwarves!

Syringe manufacturing, complete!

Use silver wire to guide the healing power at fixed points, complete!

Local anesthesia magic, completed!

Next, as long as the vines can be successfully sent into the heart, the treatment can be guided under X-ray and ultrasound, and the sealing operation can be performed... Of course, there are still a lot, a lot, and a lot to successfully complete the seal. Experiments to be done...

Gretel narrowed his eyes subconsciously. Although guiding the vines uses mental power, observing the position of the vines (and the marked silver wires) is reflected back and projected in the meditation field of vision by [Detection Magic], neither of which requires eyes. However, it seems that only this action can make him see more clearly:

The sinoatrial node above the right atrium lights the fire of life. The atria contract, the mitral and tricuspid valves relax, and blood is squeezed into the ventricles;

The most powerful muscles of the heart on the ventricular wall are stimulated to contract by the electrical signals sent by the sinoatrial node, causing the most powerful contraction. At the same time, the aortic valve opens, and the arterial blood carrying rich oxygen is pumped into the aorta by strong pressure, while the tentative vine that has been wandering in the aortic arch raises its head and goes upstream, directly inserting into the left ventricle;

The ventricular wall relaxes, the aortic valve closes, and the vines and silver wires are caught in the middle of the aortic valve, unable to advance or retreat;

After going through a cycle of relaxation-diastitation-atrial contraction-ventricular contraction again, the vines contract and retreat sharply!

Oops, I didn’t exit!

The normal heart rate of a rabbit is 180 to 250 beats per minute. During this period, ventricular systole—the time it takes for the heart to pump blood to the aorta—according to the way the human heart operates, is about 3/8 of the cardiac cycle. In other words, he has to complete the operation of pulling out the vines within 0.125 seconds...

Don't panic. Even if it is temporarily stuck in the middle of the aortic valve and cannot be pulled out in time, the rabbit will not die. Dr. Forsman, the pioneer of cardiac catheterization technology, inserted the catheter into the right atrium and took an X-ray. There is plenty of time.

No wonder the boss chose to insert the left median cubital vein into the right atrium... The catheter enters the right atrium from the superior vena cava, there is no valve, it is smooth and silky!

try again!

try again!

OK, it worked!

Grete let out a breath of air. It must be said that manipulating vines is easier than manipulating guide wires, it only requires concentration. As for the guide wire, the guide wire with a diameter of 1 mm travels in the blood vessel, entering 30 cm, 40 cm, 1 meter, turning, and crossing the fork, all depends on the doctor's skill.

Imagine that you are one meter away, shaking a 1 mm thick guide wire in the midst of turbulent blood flow. Let it turn 30 degrees, 60 degrees, move the tip left/right/up/down 1.5 mm, enter a certain bifurcation, and penetrate into the lower blood vessels...

Anyway, Grete had always admired the big guys in the vascular department in his previous life.

He held the vine seeds with his right thumb, index finger, and middle finger, manipulated the vine to exit, and pulled the silver wire to move backward. The only trouble with pinching a silver wire is that you have to pull it out bit by bit. If you just use vines, just cancel the spell and the vines will disappear...

Gee, how do you develop a vine that can develop within the body? I have to ask my mentor later, or ask Elder Wood?

Grete pondered and thought, but his hands were not slow at all. The vine wrapped around the silver wire and came to the entrance of the femoral artery, but instead of withdrawing immediately, it turned around and went down to the popliteal artery. The vine suddenly reared up and "bited" the wall of the popliteal artery.

Gretel's fingers were already covered with glycerin. Under the magic of B-ultrasound, you can see that near the blood vessel wall, the entire image is blurred, like a mosaic. Well, the blood vessel wall ruptures, blood flows out, the required effect is achieved, and it can be treated!

He immediately activated the healing technique, followed the silver thread up, and gathered a small group of light at the location of the wound. Stop bleeding and heal blood vessel walls…

Under visual inspection, it can be seen that the injured area no longer continues to bulge, and the blurred area under the B-ultrasound magic no longer expands. Very good, the treatment from inside the blood vessels was successful. Let’s see if there will be any sequelae!

Gretel held his breath and carefully continued to manipulate the vines to exit. When the tip of the silver wire left the rabbit's femoral artery, Grete threw out a treatment technique, couldn't wait to take out the microscope, and directly hit the silver wire onto the stage.

thrombus!

thrombus!

How many clots will be produced if the silver wire travels in the body for such a long time? In previous lives, interventional surgeries, whether interventional examinations or interventional treatments, all required heparin anticoagulation!

Not to mention, if a treatment is launched inside a blood vessel, how many clots will be hanging on it? Will it cause thrombosis and affect the patient's life safety?

Alas, interventional surgery without heparin sodium is always panicky...

Fortunately, there is only one silver thread. Unlike the guide wire of the previous life, which seemed to be 1 mm in diameter, it had a double-layer structure, with a steel core on the inside and a layer of spring coils tightly wound on the outside. The surface area of ​​the silver wire is so much smaller, so the blood clotting caused by it should be much less... right?

"Gretel, why are you inserting vines into its heart?"
