RESUMO

BACKGROUND: Organ procurement and transplant activity from controlled donation after circulatory death (DCD) was evaluated over an 11-year period to determine whether this program influenced the transplant and donation after brain death (DBD) activities. MATERIAL AND METHODS: Deceased donor (DD) procurement and transplant data were prospectively collected in a local database for retrospective review. RESULTS: There was an increasing trend in the potential and actual DCD numbers over time. DCD accounted for 21.9% of the DD pool over 11 years, representing 23.7% and 24.2% of the DD kidney and liver pool, respectively. The DBD retrieval and transplant activity increased during the same time period. Mean conversion rate turning potential into effective DCD donors was 47.3%. Mean DCD donor age was 54.6 years (range, 3-83). Donors ≥60 years old made up 44.1% of the DCD pool. Among referred donors, reasons for nondonation were medical contraindications (33.7%) and family refusals (19%). Mean organ yield per DCD donor was 2.3 organs. Mean total procurement warm ischemia time was 19.5 minutes (range, 6-39). In 2012, 17 DCD and 37 DBD procurements were performed in the Liege region, which has slightly >1 million inhabitants. CONCLUSIONS: This DCD program implementation enlarged the DD pool and did not compromise the development of DBD programs. The potential DCD pool might be underused and seems to be a valuable organ donor source.

RESUMO

INTRODUCTION: Delayed graft function (DGF) occurs more frequently in kidney transplants from donation after cardiac death (DCD) than from donation after brain death (DBD). We investigated the effect of DGF on posttransplantation outcomes among grafts from controlled DCD kidneys. PATIENTS AND METHODS: This single-center retrospective study recruited 80 controlled DCD kidneys transplanted from January 2005 to December 2011. Mean patient follow-up was 28.5 months. RESULTS: There were no primary nonfunction grafts; the DGF rate was 35.5%. Overall graft survival rates between groups with versus without DGF were 92.4% and 95.2% at 1 year, 92.4% and 87.1% at 3 years, and 84.7% and 87.1% at 5 years, respectively (P = not significant (NS)). Patients with versus without DGF showed the same survival rates at the corresponding time 92.4% vs 97.2%, 92.4% vs 93.9%, and 84.7% vs 93.9% (P = NS). Estimated glomerular filtration rate was significantly lower in the DGF compared with the non-DGF group at hospital discharge (29 vs 42 mL/min; P = .00) and at 6 months posttransplantation (46 vs 52 mL/min; P = .04), but the difference disappeared thereafter: 47 vs 52 mL/min at 1 year, 50 vs 48 mL/min at 3 years, and 54 vs 53 mL/min at 5 years (P = NS). DGF did not increase the risk of an acute rejection episode (29.6% vs 30.6%; P = NS) or rate of surgical complications (33.3% vs 26.5%; P = NS). However, DGF prolonged significantly the length of hospitalization in the DGF versus the non- DGF group (18.9 vs 13 days; P = .00). Donor body mass index (BMI) ≥ 30 kg/m(2), recipient BMI ≥30 kg/m(2), and pretransplantation dialysis duration increased the risk of DGF upon multivariate logistic regression analysis. CONCLUSIONS: Apart from the longer hospital stay, DGF had no deleterious impact on the future of kidney allografts from controlled DCD, which showed comparable graft and patient survivals, renal function, rejection rates, and surgical complications as a group without DGF. Therefore, DGF should no longer be considered to be a medical barrier to the use of kidney grafts from controlled DCD.

RESUMO

Non-heart-beating (NHB) organ donation has become an alternative source to increase organ supply for transplantation. A NHB donation program was implemented in our institution in 2002. As in many institutions the end of life care of the NHB donor (NHBD) is terminated in the operating room (OR) to reduce warm ischemia time. Herein we have described the organization of end of life care for these patients in our institution, including the problems addressed, the solution proposed, and the remaining issues. Emphasis is given to our protocol elaborated with the different contributors of the chain of the NHB donation program. This protocol specifies the information mandatory in the medical records, the end of life care procedure, the determination of death, and the issue of organ preservation measures before NHBD death. The persisting malaise associated with NHB donation reported by OR nurses is finally documented using an anonymous questionnaire.

RESUMO

OBJECTIVE: In this study, we have evaluated the organ procurement and transplantation activity from donors after cardiac death (DCD) at our institution over an 8-year period. Our aim was to determine whether this program influenced transplantation programs, or donation after brain death (DBD) activity. METHODS: We prospectively collected our procurement and transplantation statistics in a database for retrospective review. RESULTS: We observed an increasing trend in potential and actual DCD number. The mean conversion rate turning potential into effective donors was 58.1%. DCD accounted for 16.6% of the deceased donor (DD) pool over 8 years. The mean age for effective DCD donors was 53.9 years (range, 3-79). Among the effective donors, 63.3% (n = 31) came from the transplant center and 36.7% (n = 18) were referred from collaborative hospitals. All donors were Maastricht III category. The number of kidney and liver transplants using DCD sources tended to increase. DCD kidney transplants represented 10.8% of the DD kidney pool and DCD liver transplants made up 13.9% of the DD liver pool over 8 years. The DBD program activity increased in the same time period. In 2009, 17 DCD and 33 DBD procurements were performed in a region with a little >1 million inhabitants. CONCLUSION: The establishment of a DCD program in our institution enlarged the donor pool and did not compromise the development of the DBD program. In our experience, DCD are a valuable source for abdominal organ transplantation.

RESUMO

Although acute hepatitis may be a side effect of many medications, most cases are reversible after treatment interruption, and fulminant hepatic failure (FHF) is rare. Venlafaxine and trazodone are 2 popular antidepressant agents. Alteration of liver enzyme levels has been reported as a side effect of these drugs at normal doses. Herein we have reported the case of a 48-year-old woman without any previous history of liver disease, who developed fulminant liver failure after 4 months of venlafaxine and trazodone therapy. She required liver transplantation, a procedure that was successful with full patient recovery. The first 5 years of follow-up were uneventful. This case documented that venlafaxine and trazodone at normal doses can produce severe liver toxicity. Liver tests should be monitored regularly in patients who receive this therapy.

RESUMO

OBJECTIVE: Donation after cardiac death (DCD) has been proposed to overcome in part the organ donor shortage. In liver transplantation, the additional warm ischemia time associated with DCD procurement may promote higher rates of primary nonfunction and ischemic biliary lesions. We reviewed the results of liver transplantation from DCD. PATIENTS AND METHODS: From 2003 to 2007, we consecutively performed 13 controlled DCD liver transplantations. The medical records of all donors and recipients were retrospectively reviewed, evaluating in particular the outcome and occurrence of biliary complications. Mean follow-up was 25 months. RESULTS: Mean donor age was 51 years, and mean intensive care unit stay was 5.4 days. Mean time between ventilation arrest and cardiac arrest was 9.3 minutes. Mean time between cardiac arrest and arterial flushing was 7.7 minutes. No-touch period was 2 to 5 minutes. Mean graft cold ischemia time was 295 minutes, and mean suture warm ischemia time was 38 minutes. Postoperatively, there was no primary nonfunction. Mean peak transaminase level was 2546 UI/mL. Patient and graft survival was 100% at 1 year. Two of 13 patients (15%) developed main bile duct stenosis and underwent endoscopic management of the graft. No patient developed symptomatic intrahepatic bile duct strictures or needed a second transplantation. CONCLUSIONS: Our experience confirms that controlled DCD donors may be a valuable source of transplantable liver grafts in cases of short warm ischemia at procurement and minimal cold ischemia time.

RESUMO

INTRODUCTION: There is some controversy on the necessity of venous reconstruction of the right paramedian sector (segments V and VIII) during right lobe living related liver transplantation. In this report we describe the evolution of posttransplant graft function in five consecutive right lobe recipients without specific drainage of the right paramedian sector. MATERIAL AND METHODS: The technique of common right hepatectomy for right lobe graft harvesting and transplantation did not include the middle hepatic vein in the graft. The mean total ischemic time was 51 minutes (ranges: 35 to 64 minutes). The mean graft to recipient weight ratio was 1.35% +/- 0.15%. No patient developed small-for-size syndrome. RESULTS: All patients showed a rise in transaminases with a maximum at postoperative day 2 (mean aspartate aminotransferase: 1067 +/- 432 IU/mL). Liver function improved rapidly, with coagulation normalized at postoperative day 5. Bilirubin decreased progressively to normalize in three patients at postoperative day 14. Ultrasonography and computed tomography demonstrated that the paramedian sector of the right liver was congested, a state that was temporary with normalization of the liver tests and congestion disappeared at follow-up. No complication was linked to congestion. DISCUSSION: This series showed that in right lobe liver transplantation with a relatively large-size graft, reconstruction of the hepatic veins of the paramedian sector may not be necessary despite the induction of some degree of venous congestion. In smaller grafts, this congestion might be avoided by reconstruction of the large veins draining segments V and VIII.

RESUMO

PURPOSE: To compare CT and radionuclide imaging of osmotic blood-brain barrier disruption. To develop a quantitative method for imaging osmotic blood-brain barrier disruption and to see if iopamidol could be safely given intravenously in conjunction with blood-brain barrier disruption. METHODS: Forty-five blood-brain barrier disruption procedures were imaged with CT and radionuclide scans. The scans were evaluated with visual and quantitative scales. Patients were observed for adverse effects after blood-brain barrier disruption. RESULTS: There was a 4% rate of seizures in this study. There was good agreement between visual CT and radionuclide grading systems. Quantitative methods to grade disruption did not add useful information to visual interpretations. CONCLUSIONS: Nonionic iodine-based contrast medium has a lower incidence of seizures when injected intravenously in conjunction with osmotic blood-brain barrier disruption than ionic contrast material. Contrast-enhanced CT is the preferred method to image disruption because it has better spatial resolution than radionuclide techniques.
