Abstract: Living donor lobar lung transplantation (LDLLT) was developed in order to mitigate the growing competition for deceased donor (DD) lungs and resultant increase in waiting list mortality. Because each of the two donor lobes serves as an entire lung for the recipient, donors who are taller than the recipient are preferred. Therefore LDLLT is particularly well suited for pediatric recipients for whom adults serve as donors. Although long-term outcomes after LDLLT reported by the Organ Procurement and Transplantation Network (OPTN) are worse compared with DD recipients, overall pediatric outcomes as well as single center reports from the most experienced programs are more promising. Particularly encouraging are the findings that bronchiolitis obliterans (OB) is less frequent or less severe in LDLLT recipients in comparison to DD recipients. Moreover, outcomes may be improved by careful selection of donors to ensure adequately sized donor lobes and minimization of infectious risks. Although no donor deaths have been reported, there is a moderate risk of significant short-term complications. Long-term follow-up has not been reported. The use of LDLLT has decreased in recent years, and the recent change by the OPTN to an urgency/benefit allocation system for DD lungs in patients 12 yr and older may further reduce the demand. Nonetheless, we anticipate that LDLLT will continue to be utilized in select circumstances, particularly in children under 12 where access to DD organs remains challenging.
