To further evaluate the impact of tPA in reduction of ITBS in livers recovered from the DCD donors we conducted a controlled randomized trial. Between 2010 and 2013, 23 recipients of livers from DCD donors were enrolled (12 no tPA, and 11 tPA). During the same period another 57 recipients of livers from DCD donors (22 no tPA, and 35 tPA) were transplanted. All patients were followed for minimum 12 months. The donor and recipients age, MELD score, warm and cold ischemia time in all groups (Table 1) were similar. ITBS was seen in two patients; one no tPA in randomized group, and one in tPA nonrandomized recipients and both were retransplanted.
Four livers developed PNF (1 tPA, and 3 no tPA) and one liver in no tPA group developed hepatic artery stenosis leading to re-transplantation. Early complications (PNF, HAS, TIBS) happened in 2/46 (4.3%) in tPA, and 5/34 (14.7%) in no tPA group
|Number||Age at Tx||MELD score||Donor age||Warm ischemia time||Cold ischemia time|
|TPA protocol||11||61.8 +/- 5.9||22 +/- 5||33 +/- 14||21 +/- 7||389 +/- 36|
|No TPA protocol||12||56 +/- 11||23 +/- 5||40 +/- 13||23 +/- 4||373 +/- 76|
|TPA Nonprotocol||35||56 +/- 9||22 +/- 7||42 +/- 14||24 +/- 7||387 +/- 68|
|No TPA Nonprotocol||22||56 +/- 11||23 +/- 6||37 +/- 13||25 +/- 7||389 +/- 107|
Conclusion: While the incidence of ITBS and other complications (PNF, HAT) in the non-tPA group was lower than earlier reported estimates (50%) thus limiting the power of comparison, these findings suggest that the reduction in these complications in the tPA group may be related to tPA use, in addition to other factors, such as limiting cold and warm ischemia times when using DCD livers.
