BACKGROUND: Optimal size matching is critical to avoid problems from oversized grafts used in lung transplantation for restrictive @entity358 in @entity1 with a small chest cavity. Although graft volume reduction (GVR) is useful to overcome related disparities, its merits and demerits remain unclear. METHODS: We performed 342 lung transplants during the period of January 2003 to April 2007. Of the lung transplant recipients, 167 recipients had end-stage restrictive @entity358 , with 25 (15%) receiving grafts considered to be oversized because of height disparity. The present retrospective analysis was conducted to compare between @entity1 with size-matched and oversized grafts, and @entity1 who did (GVR group, n = 9) and did not (non-GVR group, n = 16) undergo GVR for an oversized graft. RESULTS: Pulmonary functional improvement after 6 months was better in size-matched @entity1 in view of percent forced vital capacity (FVC%) increase (29.8% vs 21.2%, p < 0.05), whereas long-term survival was not significantly different between the size-matched and oversized groups. Compared with the GVR group, the non-GVR group had a significantly higher incidence of short-term complications leading to @entity1576 (50% vs 11.1%, p < 0.05), whereas functional improvement was significantly worse in the non-GVR group (FVC% increase: 32.8% vs 19.9%, p < 0.05). However, overall @entity1 survival at 3 years was not significantly different (non-GVR: 67%; GVR: 75%). CONCLUSIONS: An oversized graft may lead to a higher incidence of short-term clinical complications with @entity358 improvement post-operatively in lung transplantation recipients with end-stage restrictive @entity358 . The decision of whether to carry-out GVR at the time of transplantation with an oversized graft to improve outcome is of critical importance.
