The shattered half of the face and arm are still in the fridge, and now they're dealing with this gigantic vascular tumor in the abdomen.
Imagine a patient with severe splenic rupture, the spleen must be removed to stop bleeding and save the life, because there are many "venous sinuses" in the spleen. A severely ruptured spleen would bleed everywhere, making haemostasis impossible. The only solution is to tie off the blood vessels at the base of the spleen, and cut off the organ, thus ending the bleeding from the spleen.
Now, this vascular tumor has over a hundred stems, and the tumor body itself is twisted strands of blood vessels. If seriously damaged, it could bleed even more viciously than ordinary organs.
If there were no on-site blood transfusions, the patient wouldn't have made it to the hospital alive; even at the hospital, it's only the constant blood transfusions and the use of autologous blood recovery equipment that've kept him viable for the operating table.
