The use of marginal-suboptimal donor organs: a practical solution for organ shortage

Area of Science:

• Transplantation immunology
• Organ procurement and preservation
• Surgical techniques in transplantation

Background:

• Increasing incidence of end-stage organ failure leads to a rising demand for organ transplantation.
• The supply of organs from ideal cadaver donors is insufficient to meet this growing demand.
• Many potentially viable "marginal" or "suboptimal" organs are discarded, contributing to organ shortage.

Purpose of the Study:

• To review data on the utilization of marginal donor organs.
• To assess the viability of using suboptimal organs to address organ shortage.
• To determine the potential increase in donor organ supply through marginal organ utilization.

Main Methods:

• Review of data from the authors' experience and other transplant centers.
• Analysis of outcomes using marginal donor organs, including those from donors >55 years, children <5 years, diabetics, non-heart beating cadavers, and organs with extended preservation.
• Evaluation of the impact of appropriate surgical techniques and immunosuppression protocols.

Main Results:

• Utilization of marginal donor organs has been confirmed as a viable strategy to overcome organ shortage.
• Successful transplantation outcomes can be achieved with appropriate surgical and immunosuppressive management.
• The use of marginal organs can increase the overall supply of donor organs by an estimated 25% to 30%.

Conclusions:

• Marginal donor organs represent a valuable, underutilized resource in organ transplantation.
• Appropriate management strategies can mitigate risks associated with using suboptimal organs.
• Increased utilization of marginal organs is crucial for addressing the organ transplant waiting list crisis.
