The Surgeon’s Studio

er trial.

In the past, he would definitely not do this.

It was easy to go down the slippery slope of luxury.

After he finished changing, Zheng Ren told Professor Rudolf to prepare the preoperative measures.
He then entered the smoking-room and lit up a cigarette before entering the System.

He bought some surgical training time.
The System’s operating room emerged from the ground and the simulation mannequin appeared right in front of Zheng Ren.

The lumbar arteries were parallel with the intercostals.
There were usually four of them, two each arising from the front and back of the intervertebral foramen.

The arteries in front passed through the transverse process, which continued along the intertransverse ligament.
They then pierced through the posterior aponeurosis of the transversus abdominis and were carried forward between this muscle and the obliquus internus to supply blood to the posterior abdominal wall.

The arteries at the back passed through a finer intervertebral foramen into the spinal canal to provide blood supply to the anterior spinal dura mater and the posterior vertebral column.

At the same location, the posterior branch then continued behind to supply the lumbar plexus.

Not only did he need to perform embolization on the posterior branch, but he also had to embolize the abnormal growth of blood vessels from the main branches and the tumor.

He had already confirmed this in the afternoon when he did the 64-slice CT scan with three-dimensional image reconstruction.

Since the patient had an advanced tumor, this was also considered to be a palliative surgery to improve the patient’s quality of life post-surgery.
Therefore, they had to try their best to block the abnormal arteries supplying to the spine and avoid introducing complications at the same time.

A simple destructive operation would not be this difficult.
Without the embolization of the lumbar arteries in the past, the bleeding volume during surgery would be around 3 to 5 liters.

This was a terrifying number.

If they embolized the lumbar arteries, the bleeding could be controlled under an acceptable range of 1.5 to 2 liters.

Zheng Ren used almost 3 hours to complete his first surgical training.

Zheng Ren decided that he was not only going to embolize the posterior branch even though that method would be much easier and satisfy the requirements of an orthopedic surgeon from Imperial Capital.

However, losing 1.5 liters of blood would significantly affect the patient’s life.

In order to increase the patient’s quality of life in their last remaining days, they needed to minimize the bleeding.

He needed to embolize the intercostal arteries on both sides, the lumbar arteries, and the surrounding capillaries in order to reduce blood loss during surgery.

In reality, there was no need for Zheng Ren to do that.

However, as a doctor, one would always give their best to improve the patient’s recovery if the situation allowed.
If there was no chance of recovery, they would always try to improve their quality of life.

The blood supply to the spinal cord was very rich.
Other than the need to avoid the Adamkiewicz artery, Zheng Ren would need to carefully scan the other arteries and check if they were connected to other organs or the spinal cord.
It was only then that he would cut off the arteries that supplied blood only to the tumor.

The surgery progressed very slowly.
Zheng Ren gradually got a grasp on the embolization techniques.

It was not easy to be at the Grandmaster level.

Even after completing 10 surgical training, Zheng Ren could only complete the lumbar artery embolization surgery within two hours.

Just to qualify under Zheng Ren’s standards, this surgery was much more difficult than prostate interventional surgery.

This was because even if he embolized the wrong capillaries in the prostate, it would not cost the patient’s life.

Similar to the patient treated by Professor Rudolf Wagner whose superior vesical artery got embolized, the patient only had urinary incontinence which could be solved by a urinary catheter.

This time, he was going to embolize arteries from the spinal cord’s blood supply.

One mistake would paralyze the patient’s lower body and even cause respiratory arrest and lead to the patient’s death.
