Which vessel is most commonly cannulated for insitu perfusion of cadaver donor kidneys?

• A. Femoral vein
• B. Distal aorta
• C. Renal artery
• D. Superior vena cava

Answer: (B)

The most commonly cannulated vessel for in situ perfusion of cadaver donor kidneys is the distal aorta. In the context of organ transplantation, particularly for kidney procurement, maintaining perfusion of the kidneys is crucial to preserve their viability prior to transplantation. The distal aorta is typically selected because it allows for effective delivery of the preservation solution to both kidneys simultaneously, promoting adequate perfusion throughout the renal vascular system. Cannulating the distal aorta provides a pathway to ensure that the solution flows through the renal arteries, which are branches off the aorta, enabling the kidneys to be adequately perfused while they are still in situ. This method helps to maintain kidney function and cellular integrity until the organs can be transplanted into the recipient. Other vessels mentioned, while potentially useful in different contexts, do not provide the comprehensive perfusion necessary for the kidneys during the organ recovery process. For example, the renal artery would only perfuse one kidney at a time and would not ensure sufficient delivery of solution to both kidneys like the distal aorta would. Therefore, the distal aorta is the most appropriate choice for this purpose.
