The thymus is already very close to the heart, and after the patient developed a tumor in the thymus, it has directly encroached upon a part of the pericardium.
The artery that was damaged is now directly ligated and obstructed.
It's as if that route for blood flow has been cut off.
The human body's entire blood supply system is very delicate. Especially the blood vessels within the thoracic cavity.
Whether veins or arteries, they all form a systemic blood circulation system centered around the heart.
Blood supplied from the thoracic cavity reaches as high as the brain and as low as the soles of the feet, supplying all of a person's limbs and internal organs.
The patient's blood oxygen level is continuously dropping; whether this is related to the severed artery is not yet clear.
But without completely separating the thymus tumor, there is no way to suture that artery now!
Director Hu Kan is facing an unprecedented challenge.
