Takashi Fujita, MD, Hiroshi Date, MD, Kouji Ueda, MD, Itaru Nagahiro, MD, Motoi Aoe, MD, Akio Andou, MD, Nobuyoshi Shimizu, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 123, Issue 1, Pages (January 2002) DOI: /mtc Copyright © 2002 American Association for Thoracic Surgery Terms and Conditions

2 Fig. 1 Relationship between size parameters and mean PAP at 1 hour after reperfusion; A, D/R body-weight ratio; B, D/R heigh ration; C, D/R chest-circumference ratio; D, D/R lung-weight ratio. A significant negative correlation was present between D/R body-weight ratio and mean PAP at 1 hour r = –0.594, P =.025).

3 Fig. 2 Relationship between size parameters and Pao2 at 6 hours after reperfusion: A, D/R body-weight ratio; B, D/R height ratio; C, D/R chest-circumference ratio; and D, D/R lung-weight ratio. A significant correlation was present between D/R body-weight ratio and Pao2 at 6 hours (r = 0.704, P =.007).

4 Fig. 3 Relationship between D/R body-weight ratio and Pao2 at 6 hours after reperfusion. All recipients with a D/R body-weight ratio of 1.2 or greater had Pao2 exceeding 500 mm Hg, and they were classified in group 1. In contrast, all recipients with D/R body-weight ratio of less than 1.2 had Pao2 of less than 500 mm Hg or died before 6 hours, and they were classified in group 2.

5 Fig. 4 Wet/dry lung-weight ratio of transplanted lung after 6-hour assessment period. It was significantly lower in group 1 (6.43 ± 0.59, P =.036). The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /mtc ) Copyright © 2002 American Association for Thoracic Surgery Terms and Conditions
