The deceased organ donor with an "open abdomen": proceed with caution.

In solid organ transplantation, the disparity between donor supply and patients awaiting transplant continues to increase. The organ shortage has led to relaxation of historic contraindications to organ donation. A large percentage of deceased organ donors have been subjected to traumatic injuries, which can often result in intervention that leads to abdominal packing and intensive care unit resuscitation. The donor with this "open abdomen" (OA) presents a situation in which the risk of organ utilization is difficult to quantify. There exists a concern for the potential of a higher risk for both bacterial and fungal infections, including multidrug-resistant (MDR) pathogens because of the prevalence of antibiotic use and critical illness in this population. No recommendations have been established for utilization of organs from these OA donors, because data are limited. Herein, we report a case of a 21-year-old donor who had sustained a gunshot wound to his abdomen, resulting in a damage-control laparotomy and abdominal packing. The donor subsequently suffered brain death, and the family consented to organ donation. A multiorgan procurement was performed with respective transplantation of the procured organs (heart, liver, and both kidneys) into 4 separate recipients. Peritoneal swab cultures performed at the time of organ recovery grew out MDR Pseudomonas aeruginosa on the day after procurement, subsequently followed by positive blood and sputum cultures as well. All 4 transplant recipients subsequently developed infections with MDR P. aeruginosa, which appeared to be donor-derived with similar resistance patterns. Appropriate antibiotic coverage was initiated in all of the patients. Although 2 of the recipients died, mortality did not appear to be clearly associated with the donor-derived infections. This case illustrates the potential infectious risk associated with organs from donors with an OA, and suggests that aggressive surveillance for occult infections should be pursued.

Recombinant tissue-type plasminogen activator in the treatment of acute renal artery thrombosis after kidney transplantation.

Acute arterial thrombosis is an uncommon but potentially devastating consequence of kidney transplantation. Early recognition followed by thrombectomy may salvage the graft. We present a case of acute renal artery thrombosis after a living-related kidney transplant with successful treatment with operative thrombectomy and intraarterial infusion of recombinant tissue-type plasminogen activator.
