I think it's when the patient needs more than one organ transplanting (within the same operation); lots of patients have a joint heart/lung transplant at the same time, since it's easier than just transplanting the heart.
The liver starts to fail only when more than half of it is damaged
The principal diagnosis for a patient with end-stage renal failure admitted for a liver transplant with a history of liver transplant failure is end-stage renal disease (ESRD). This condition is critical as it requires the patient to be evaluated and managed for their renal status before proceeding with the liver transplant. The history of liver transplant failure is also significant but serves more as a complicating factor rather than the primary diagnosis in this context.
One is not "better" than the other - they will both perform exactly the same as a non transplanted heart or lungs. Neither will make the patient bionic or superhuman. A patient with heart failure would rather have a heart transplant than a lung transplant, and vice versa. It's whatever it "better" (more useful) for the patient, but neither hearts or lung transplants are "better" overall.
A human being cannot live more than a few minutes without a functioning liver. During a liver transplant operation, a machine substitutes the function of the liver
No, this is wrong. The left is taller, because the right is bulged by the diaphragm due to the presence of liver.
A transplant surgeon basically transplants donated organs into someone's body that needs them. There are 4 types of transplants currently: Kidney Liver Pancreas Heart (done by cardiothoracic surgeons, not transplant surgeons in most cases)
No, neither is entitled to a liver transplant by way of their status. It's by the generosity of the donor who died that one be available, and if the liver has been donated by typical means, then it's left up to a bureaucracy to decide the recipient on behalf of the donor.
Other than a liver transplant the is hardly an ideal solution, there is no cure for Hemophilia A or B as of yet.
Its bigger because the right lung has more lobs then the left lung.
Each lung has more than one "lobe" or section. The right lung has three, and the left lung has only two to leave room for the heart where the upper left lobe would be.
The average time for an organ transplant operation is around 8 hours, but this timing can vary quite significantly depending upon how "easy" the surgery is. For example, first transplants are easier to do than retransplants, single transplants are easier than multiple-organ transplants. The number of transplant surgeons available and how experienced they are will also have a bearing on surgery times. Most transplants will fall within the range of 6 - 14 hours, although it is feasible that a large multiple-organ transplant could take longer.
