What is true about the recovery of tissue typing material after organ removal for transplant?

• A. Tissue typing material is not needed if a complete type has been rendered by the pre-typing material
• B. Inguinal lymph nodes should be obtained
• C. The spleen and as many lymph nodes as possible should be recovered
• D. The spleen must be removed and left whole

Answer: (C)

The recovery of tissue typing material after organ removal for transplant is crucial for ensuring compatibility between the donor organ and the recipient. Obtaining the spleen and as many lymph nodes as possible is important because these tissues provide valuable information regarding the immune response and histocompatibility. The spleen contains a wealth of lymphocyte populations that can significantly aid in determining tissue typing through analysis of T and B cells. In contrast, while pre-typing can provide initial compatibility data, there still remains uncertainty that necessitates tissue sampling post-removal for a more accurate assessment. The recovery of lymph nodes is particularly beneficial as they can have a diversity of immune cells and antigenic material, which contribute to a comprehensive understanding of tissue compatibility. This ensures that any transplant undertaken has the best chance of success with minimal risk of rejection. The other methods of recovery mentioned do not prioritize the broader immunological appraisal needed for tissue typing. For instance, while inguinal lymph nodes may sometimes be indicated, they do not generally provide the same level of comprehensive data as the spleen and other regional lymph nodes. Regarding the spleen being left whole, while it’s essential that the spleen is harvested for its immunological significance, it may not be necessary to leave it intact as various
