Abstract
Background Surgical techniques of liver transplantation have continually evolved and have been modified. We retrospectively analyzed a single-center case series and compared the advantages and disadvantages of each method. Methods Six-hundred and seventy-four recipients’ perioperative data were assessed and analyzed stratified by different surgical technics [modified classic (MC), modified piggyback (MPB) and classic piggyback (CPB)]. Results MELD score and Child-Pugh scores was significantly higher in CPB groups (P=0.008 and 0.003, respectively). Anhepatic time in MPB group was longer than those in CPB group (P<0.05). The operation duration in MPB group was significantly longer than those in MC group and CPB group (P=0.003). Three patients had outflow obstruction (P=0.035). The overall survival in MPB group were better than those in MC group and CPB group in general comparison (P<0.001). In patients with preoperative creatine >120 µmol/L, the overall survival in MC group was worst (P<0.001). In patients with a high MELD score (>24), the overall survival in MPB group tended to be the best (P<0.001). Conclusions The advantages and disadvantages are different for these three surgical techniques. A reasonable operation technique should be adopted considering the patient's unique condition to ensure the stability of hemodynamics.

Abstract
PURPOSE To investigate the association between pretransplant intra-arterial liver-directed therapy (IAT) for hepatocellular carcinoma (HCC) and hepatic arterial complications (HAC) in orthotopic liver transplantation (OLT) [namely hepatic artery thrombosis (HAT) and/or the need for hepatic arterial conduit]. METHODS A total of 175 HCC patients (mean age: 60 years) underwent IAT with either transarterial chemoembolization or yttrium-90 (90Y) transarterial radioembolization prior to OLT between 2003 and 2013. A matched control cohort of 159 HCC patients who underwent OLT without prior IAT was selected. Incidence of HAC in both cohorts was investigated. The categorical differences between both cohorts were calculated by chi-square test. RESULTS Among the 175 patients (chemoembolization, n = 82; radioembolization, n = 93), 8 (5%) required conduits due to HA disease (chemoembolization, n = 6; radioembolization, n = 2), 3 (2%) developed HAT (chemoembolization, n = 2; radioembolization, n = 1). Eleven of 175 patients (6.7%) had HAC. Of the 159 control patients, 6 (4%) needed conduits for HA disease and 3 (2%) developed HAT. Nine of 159 patients (5.7%) had HAC. Chi-square analysis between the IAT cohort and the control group yielded a p value of 0.810. When comparing chemoembolization to radioembolization, p = 0.076 (not significant at p < 0.05). CONCLUSION Although aggressive pretransplant radioembolization and chemoembolization are both utilized in most liver transplant centers, neither appears to increase the risk of peri-transplant hepatic arterial complications in HCC patients.

Abstract
Donor organ shortage continues to limit the availability of liver transplantation, a successful and established therapy of end-stage liver diseases. Strategies to mitigate graft shortage include the utilization of marginal livers and recently ex-situ normothermic machine perfusion devices. A 59-year-old woman with cirrhosis due to primary sclerosing cholangitis was offered an ex-situ machine perfused graft with unnoticed severe injury of the suprahepatic vasculature due to road traffic accident. Following a complex avulsion, repair and reconstruction of all donor hepatic veins as well as the suprahepatic inferior vena cava, the patient underwent a face-to-face piggy-back orthotopic liver transplantation and was discharged on the 11th postoperative day after an uncomplicated recovery. This report illustrates the operative technique to utilize an otherwise unusable organ, in the current environment of donor shortage and declining graft quality. Normothermic machine perfusion can definitely play a role in increasing the graft pool, without compromising the quality of livers who had vascular or other damage before being ex-situ perfused. Furthermore, it emphasizes the importance of promptly and thoroughly communicating organ injuries, as well as considering all reconstructive options within the level of expertise at the recipient center.

Abstract
OBJECTIVE To explore the risk factors of intra-abdominal bacterial infection (IAI) after liver transplantation (LT) in patients with hepatocellular carcinoma (HCC). METHODS A series of 82 HCC patients who received LT surgeries in our department between March 2004 and April 2010 was recruited in this study. Then we collected and analyzed the clinical data retrospectively. Statistical analysis system (SPSS) software was adopted to perform statistical analysis. Chi-square test, t-test and Wilcoxon rank sum test were used to analyze the clinical data and compute the significance of the incidences of early-stage IAI after LT for HCC patients. Binary logistic regression was performed to screen out the risk factors, and multiple logistic regression analyses were performed to compute the independent risk factors. RESULTS A series of 13 patients (13/82, 15.9%) had postoperative IAI. The independent risk factors of postoperative intra-abdominal bacterial infections after LT for HCC patients were preoperative anemia [Hemoglobin (HGB) <90 g/L] and postoperative abdominal hemorrhage (72 hours >400 mL), with the odds ratios at 8.121 (95% CI, 1.417 to 46.550, P=0.019) and 5.911 (95% CI, 1.112 to 31.432, P=0.037). CONCLUSIONS Postoperative IAI after LT in patients with HCC was a common complication. Preoperative moderate to severe anemia, as well as postoperative intra-abdominal hemorrhage more than 400 mL within the first 72 hours might independently indicate high risk of IAI for these patients.

Abstract
The objective of this study was to identify peritransplant predictors of early graft survival and posttransplant parameters that could be used to predict early graft outcomes after pediatric liver transplantation (PLT). The response of children to liver dysfunction after liver transplantation (LT) is poor. No data have been reported for early predictors of poor graft survival, which would potentially be valuable for rescuing children at risk after LT. A retrospective cohort study of 422 PLT procedures performed from 2000 to 2010 at a single center was conducted. Multiple peritransplant variables were analyzed. Univariate and multivariate analyses using receiver operating characteristic curves were performed to identify predictors of early graft loss (ie, at 30, 60, and 90 days). The number needed to treat (NNT) was calculated when the risk factors were identified. Comparisons with the Olthoff criteria for early graft dysfunction in adults were performed. The overall 30-, 60-, and 90-day graft survival rates were 93.6%, 92.6%, and 90.7%, respectively. A recipient age of 0 to 2 or 6 to 16 years, acute liver failure, and a posttransplant day 7 serum bilirubin level > 200 μmol/L were risk factors for graft loss in the 3-strata Cox models. The product of the peak aspartate aminotransferase (AST) level, day 2 international normalized ratio (INR) value, and day 7 bilirubin level [with 30-, 60-, and 90-day areas under the receiver operating characteristic curve (AUROCs) of 0.774, 0.752, and 0.715, respectively] and a day 7 bilirubin level > 200 μmol/L (with 30-, 60-, and 90-day AUROCs of 0.754, 0.661, and 0.635, respectively) provided excellent prediction rates for early graft loss (30-days for Day-7-bilirubin level > 200) in the pediatric population (sensitivity = 72.7%, specificity = 96.6%, positive predictive value = 95.5%, negative predictive value = 78%). The NNT with early retransplantation when the day 7 bilirubin level was >200 μmol/L was 2.17 (unadjusted) or 2.76 (adjusted for graft survival). In conclusion, 2 scores-the product of the peak AST level, day 2 INR value, and day 7 bilirubin level and a posttransplant day 7 bilirubin level > 200 μmol/L-have been identified as clinically valuable tools with high accuracy for predicting early graft loss. A more aggressive attitude to considering early retransplantation in this group may further improve survival after LT.

Abstract
Objective To summarize the experience with salvage liver transplantation (SLT) for patients with recurrent hepatocellular carcinoma (HCC) after primary hepatic resection in a single center. Methods A total of 376 adult patients with HCC underwent orthotopic liver transplantation (OLT) at Organ Transplantation Center, the First Affiliated Hospital of Sun Yat-sen University, between 2004 and 2008. Among these patients, 36 underwent SLT after primary liver curative resection due to intrahepatic recurrence. During the same period, one hundred and forty-seven patients with HCC within Milan criteria underwent primary OLT (PLTW group), the intra-operative and post-operative parameters were compared between these two groups. Furthermore, we compared tumor recurrence and patient survival of patients with SLT to 156 patients with HCC beyond Milan criteria (PLTB group). Cox Hazard regression was made to identify the risk factors for tumor recurrence. Results The median interval between initial liver resection and SLT was 35 months (1–63 months). The intraoperative blood loss (P<0.05) and transfusion volume (P<0.05) were larger in the SLT group than in the PLTW group. The operation time was longer in the SLT group (P<0.05). The post-operative complications incidence, tumor recurrence rate, patients' survival rate, and tumor-free survival rate were comparable between these two groups (all P>0.05). When compared to those patients with HCC beyond Milan criteria undergoing primary OLT, patients undergoing SLT achieved a better survival and a lower tumor recurrence. Cox Proportional Hazards model showed that vascular invasion, including macrovascular and microvascular invasion, as well as AFP level >400 IU/L were risk factors for tumor recurrence after LT. Conclusions In comparison with primary OLT, although SLT is associated with increased operation difficulties, it provides a good option for patients with HCC recurrence after curative resection.

Abstract
BACKGROUND To explore the relationship between Toll-like rpheral blood mononuclear cells (PBMC) and systemic inflammatory response syndrome (SIRS) in postoperative patients of liver transplantation (LT). METHODS Blood samples of 27 patients receiving LT were collected at T1 (after induction of anaesthesia), T2 (25 minutes after the beginning of anhepatic phase), T3 (3 hours after graft reperfusion), and T4 (24 hours after graft reperfusion). The expression of TLR2/4 on PBMC and serum concentration of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-8 were measured. The patients were divided into SIRS group (n = 12) and non-SIRS group (n = 15) for analysis. RESULTS Blood loss and transfusion were higher in the SIRS group than in the non-SIRS group. Both the preanhepatic and anhepatic phase were significantly longer in the SIRS group. The TLR2/4 expression on PBMC as well as serum TNF-alpha, IL-1beta, and IL-8 were significantly higher at T3 and T4 than that at T1 and T2 in the SIRS patients. The expression of TLR4 on PBMC is positively correlated to serum TNF-alpha, IL-8. Expression of TLR2/4 on PBMC and serum concentrations of TNF-alpha, IL-1beta, did not differ among the 4-time points in non-SIRS patients. CONCLUSIONS Upregulation of TLR2/4 expression on PBMC may contribute to the development of postoperative SIRS during perioperative period of LT.

Abstract
Situs inversus totalis is a rare congenital anomaly in which the heart and abdominal organs are oriented in a mirror image of normal. It provides a unique challenge as there is no established technique for liver transplantation in these patients. Employing two major alterations from our standard technique, a liver was transplanted in the left subphrenic space of a patient with situs inversus totalis. First, the liver was flipped 180 degrees from right to left (facing backward). Second, a reversed cavaplasty (anterior, not posterior, donor suprahepatic caval incision) was performed. Otherwise, it was standard, with end-to-end anastomoses of the portal vein, hepatic artery and bile duct. Three years after the entirely uneventful transplant, the recipient continues to enjoy the benefits of a normally functioning liver. The described technique prevented torsion, kinking and tension on the anastomosed structures by allowing the liver to sit naturally in an anatomical position in the left hepatic fossa. As it required no special measurements or maneuvers, the technique was easy to execute and required no donor liver size restrictions. This novel technique, with a reversed cavaplasty and a 180 degrees right-to-left flip of the liver into a left-sided hepatic fossa, may be ideal for situs inversus totalis.

Abstract
Over the past 4 decades, the surgical techniques of liver transplantation (LTx) have permanently evolved and been modified. Among these, the modified piggyback (MPB) technique by Belghiti offers specific advantages. The objective of this study was to present our single-center experience with the MPB technique in 500 cases. Recipients' perioperative data were prospectively collected and evaluated. Postoperative and specific complications, stay in the intensive and intermediate care unit, and the mortality rate with cause of death were analyzed. Most recipients were classified as Child C (49.1%). For the patients who underwent LTx for the first time, alcoholic (23.9%) and viral (22.2%) cirrhosis and hepatocellular carcinoma (15.1%) were the prevalent indications. The overall median warm ischemia time, anastomosis duration, and operative time were 45, 108, and 320 minutes, respectively. The median intraoperative blood loss was 1500 mL. A venovenous bypass was never needed to maintain hemodynamic stability. Only in a few cases was temporary inferior vena cava clamping necessary. Most prominent surgical complications were hemorrhage, hematoma, and wound dehiscence. Renal failure occurred in 6.2% of patients. The overall median stay in the intensive and intermediate care unit was 14 days. The mortality rates within 30 and 90 days were 6.3% and 13.3%, respectively. No technique-related death occurred. The MPB technique by Belghiti is a feasible and simple LTx technique. The caval flow is preserved during the anhepatic phase, and this minimizes the need for venovenous bypass or portocaval shunt. This technique requires only 1 caval anastomosis, which is easy to perform with a short anhepatic phase. To minimize the risk of outflow obstruction, attention should be paid by doing a wide cavocavostomy cranially to the donor inferior vena cava in a door-lock manner. This technique can be applied in almost all patients undergoing LTx for the first time and liver retransplantation as well.

Abstract
We describe our experience with a modification of the piggyback (PB) technique for orthotopic liver transplantation in which the donor infrahepatic vena cava is used as the venous outflow tract. From May 1997 to January 2006, a total of 109 cases using this technique were performed in 101 patients. Collected data included recipient demographics and diagnosis, warm ischemia time, use of venovenous bypass or temporary portacaval shunt and complications related to the venous outflow and graft, and patient survival. Data were compared with the patients undergoing standard PB technique during the same period. The reasons for using the technique were grouped according to whether there was a problem with the recipient hepatic veins or a concern about the length or diameter of the donor suprahepatic vena cava. These included the presence of a trans-jugular intrahepatic portosystemic shunt (eight cases), retransplantation (22 cases), thin-walled, friable hepatic veins (32 cases), Budd-Chiari syndrome (two cases), domino liver procurement (six cases), reduced or split liver grafts (five cases), and graft inferior vena cava to recipient hepatic veins size discrepancy (34 cases). There was no graft loss. The warm ischemia time was 39.65 minutes compared with 37 minutes in the standard PB group. The long-term graft and patient survival rates were similar in the two groups. Infrahepatic vena cavocavostomy is a useful variation of the standard PB technique.

Abstract
BACKGROUND The curative effect of liver transplantation for patients with end-stage liver disease was encouraging in recent years and the 5-year patient survival rate can reach up to 70%. However, some patients might lose grafts due to a variety of reasons, including bile duct complications, vascular complications, primary non-function, graft rejection and disease recurrence etc. Liver retransplantation (re-LT) was the only available means for those patients whose initial grafts had failed, but the inferior outcomes of re-LT compared to primary liver transplantation (PLT) continue to be a major concern. This study aimed to analyze the indications for re-LT, optimal timing of re-LT, and strategies to improve the survival rate after re-LT. METHODS From January 2001 to December 2006, we performed 738 liver transplants and 39 re-LT (5.3%) at our center. A retrospective analysis was performed to identify factors (indication for re-LT, preoperative score of model for end-stage liver disease (MELD), interval to re-LT from primary liver transplantation, methods of vascular and biliary reconstruction and common causes of death) associated with survival. RESULTS Mean follow-up period was 1.8 years (1 to 5 years). Patients with MELD score less than 20 were better than those whose MELD score was > 20 and MELD score > 30 (1-year survival, 80.0% versus 50.0% and 3/5). The perioperative survival rate of patients who received re-LT at an interval of more than 30 days and less than 8 days after the initial transplantation was higher than those who received retransplantation between 8 to 30 days following the first operation (88.5% and 74.3% versus 50.0%). The main causes of death were infection (60.0%), multiple organ failure (20.0%), vascular complications (10.0%) and biliary fistula (10.0%) in perioperative period. The overall patient survival rate of 1-month, 6-month and 1-year was 80.0%, 76.7% and 66.7%, respectively. CONCLUSIONS Our study suggested the favorable results after re-LT. The analysis also showed optimal timing of operation, refined surgical techniques, individualized immunosuppressive regimen and effective prophylaxis and treatment of perioperative infection play an important role in achieving a higher survival after re-LT.

Abstract
This retrospective study reviews our experience in surveillance and early detection of cholangiocarcinoma (CC) and in using en bloc total hepatectomy-pancreaticoduodenectomy-orthotopic liver transplantation (OLT-Whipple) to achieve complete eradication of early-stage CC complicating primary sclerosing cholangitis (PSC). Asymptomatic PSC patients underwent surveillance using endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) with multilevel brushings for cytological evaluation. Patients diagnosed with CC were treated with combined extra-beam radiotherapy, lesion-focused brachytherapy, and OLT-Whipple. Between 1988 and 2001, 42 of 119 PSC patients were followed according to the surveillance protocol. CC was detected in 8 patients, 6 of whom underwent OLT-Whipple. Of those 6 patients, 4 had stage I CC, and 2 had stage II CC. All 6 OLT-Whipple patients received combined external-beam and brachytherapy radiotherapy. The median time from diagnosis to OLT-Whipple was 144 days. One patient died 55 months post-transplant of an unrelated cause, without tumor recurrence. The other 5 are well without recurrence at 5.7, 7.0, 8.7, 8.8, and 10.1 years. In conclusion, for patients with PSC, ERCP surveillance cytology and intralumenal endoscopic ultrasound examination allow for early detection of CC. Broad and lesion-focused radiotherapy combined with OLT-Whipple to remove the biliary epithelium en bloc offers promising long-term, tumor-free survival. All patients tolerated this extensive surgery well with good quality of life following surgery and recovery. These findings support consideration of the complete excision of an intact biliary tree via OLT-Whipple in patients with early-stage hilar CC complicating PSC.

Abstract
No consensus exists regarding the optimal reconstruction of the cavo-caval anastomosis in piggyback orthotopic liver transplantation (PB-LT). The aim of this study was to analyze our experience with end-to-side (ES) cavo-cavostomy. Outcome parameters were patient and graft survival and surgical complications. During the period 1995-2002 146 full-size PB-LT in 137 adult patients were performed with ES cavo-cavostomy without the routine use of temporary portocaval shunt (TPCS). In 12 patients (8%) this technique was used for implantation of second or third grafts. Veno-venous bypass was not used in any case and TPCS was performed only in eight patients (6%). One-, three- and five-yr patient and graft survival were 84%, 79% and 75%, and 81%, 74% and 69%, respectively. The median number of intraoperative transfusion of packed red blood cells (RBC) was 2.0 (range 0-33) and 30% of the patients (n = 43) did not require any RBC transfusion. Surgical complications of various types were observed after 49 LT (34%) and none of the complications was specifically related to the technique of ES cavo-cavostomy. Our experience indicates that PB-LT with ES cavo-cavostomy is a safe procedure, can safely be performed without the routine use of a TPCS, has a very low risk of venous outflow obstruction and can also be used effectively during retransplantations.

Abstract
AIM: To explore the values of suprahepatic venacavaplasty (cavaplasty) in liver transplan-tation.
METHODS: The new orthotopic liver transplantation procedure combined with cavaplasty was conducted in 103 patients.
RESULTS: There were no perioperative deaths in this study. The median operative and anhepatic-phase time in cavaplasty group (6.8 ± 0.8 h and 52.6 ± 14.5 min, respectively) were significantly shorter than those in classic and modified piggyback groups (7.4 ± 0.6 h, 86.5 ± 7.1 min; 7.9 ± 0.6 h, 78.4 ± 7.94 min) reported recently by other data, and blood loss was also less in cavaplasty group (2960 ± 1120 mL) than those in latter two groups (4662 ± 913 mL; 4441 ± 1072 mL). Post-operative acute renal failure occurred in 30 cases (29.1%), similar to that in classic group but higher than that in modified piggyback group. All the patients with acute renal failure recovered within 3 to 4 weeks.
CONCLUSION: Cavaplasty can simplify the resection procedure of the diseased liver and implantation of new liver, and reduce the operative time and blood loss during transplantation process, indicating that cavaplasty is safe, and should be clinically recommended.

Abstract
AIM: To explore the preventive effect of rapamycin on acute allograft rejection and kidney function recovery in liver transplant patients with acute kidney malfunction.
METHODS: A total of 25 liver transplant patients with acute kidney malfunction received rapamycin treatment as preventive measures for acute allograft rejection. Both the rejection rate and the change of kidney function were monitored.
RESULTS: Of the 25 cases, 23 survived till today with the longest time of 34 mo. The 3-mo acute rejection rate was 4%, and the kidney function of the 23 patients recovered to the normal range within 3 mo. It took more time to recover for the patients with impaired kidney function (45 ± 19 d) than that for the ones with normal kidney function (24 ± 15 d) before operation (P < 0.01).
CONCLUSION: Rapamycin can prevent the occurrence of acute allograft rejection for liver transplant patients with acute kidney malfunction, while not affect the recovery of kidney function.

Abstract
A retrospective study of 1058 liver transplant recipients was performed to determine: (i) the incidence, etiology, timing, clinical features and treatment of refractory ascites (RA), (ii) risk factors for RA development, (iii) predictors of RA disappearance, (iv) predictors of survival following RA and (v) the impact of RA on patient survival. Sixty-two patients (5.9%) developed RA and its disappearance occurred in 27/62 cases. Patients having hepatitis C virus (HCV) had a significantly higher hazard rate of developing RA (p < 0.00001). No other baseline characteristic was associated with RA. Cox stepwise regression analysis of the hazard rate of RA disappearance found two significant factors: HCV recurrence as the reason for developing RA implied a poorer outcome (p = 0.006), whereas an unknown reason implied a favorable outcome (p = 0.02). In addition, survival following RA was significantly poorer among patients having bacterial peritonitis or HCV recurrence. Finally, the mortality rate was significantly (nearly 8.6 times) higher in patients following RA development while it was ongoing (p < 0.00001); however, if the RA disappeared, then the additional risk of death also disappeared. This study illustrates the importance of developing an optimal treatment strategy to (i) effectively treat RA if it develops and (ii) prevent hepatitis C recurrence.

Abstract
BACKGROUND Orthotopic liver transplantation (OLT) in adult patients has traditionally been performed using conventional caval reconstruction technique (CV) with veno-venous bypass. Recently, the piggyback technique (PB) without veno-venous bypass has begun to be widely used. The aim of this study was to assess the effect of routine use of PB on OLTs in adult patients. PATIENTS AND METHODS A retrospective analysis was undertaken of 1067 orthotopic cadaveric whole liver transplantations in adult patients treated between June 1994 and July 2001. PB was used as the routine procedure. Patient demographics, factors including cold ischemia time (CIT), warm ischemia time (WIT), operative time, transfusions, blood loss, and postoperative results were assessed. The effects of clinical factors on graft survival were assessed by univariate and multivariate analyses.In all, 918 transplantations (86%) were performed with PB. Blood transfusion, WIT, and usage of veno-venous bypass were less with PB. Seventy-five (8.3%) cases with PB had refractory ascites following OLT (p=NS). Five venous outflow stenosis cases (0.54%) with PB were noted (p=NS). The liver and renal function during the postoperative periods was similar. Overall 1-, 3-, and 5-year patient survival rates were 85%, 78%, and 72% with PB. Univariate analysis showed that cava reconstruction method, CIT, WIT, amount of transfusion, length of hospital stay, donor age, and tumor presence were significant factors influencing graft survival. Multivariate analysis further reinforced the fact that CIT, donor age, amount of transfusion, and hospital stay were prognostic factors for graft survival. CONCLUSIONS PB can be performed safely in the majority of adult OLTs. Results of OLT with PB are as same as for CV. Liver function, renal function, morbidity, mortality, and patient and graft survival are similar to CV. However, amount of transfusion, WIT, and use of veno-venous bypass are less with PB.

Abstract
Advanced coronary artery disease (CAD) is increasingly common in patients awaiting orthotopic liver transplantation (OLT). Unfortunately, in patients whose coronary artery anatomy is not amenable to angioplasty, coronary artery bypass grafting (CABG) alone may precipitate hepatic decompensation. Thus, combined liver transplant and coronary artery bypass grafting (CABG-OLT) may be required to effectively treat both conditions. Clinical records were analyzed for 5 CABG-OLT procedures at a single institution. Operative indications, technical details, and postoperative course were determined for each patient. Patients undergoing CABG-OLT had a mean age of 57.8 years (range, 54-66) and were predominantly male (80%). All patients had significant 3-vessel coronary atherosclerotic disease with preserved left ventricular function. There were no intraoperative deaths. At mean 25 months of follow-up (range, 8.0-25) there was an 80% graft and patient survival. Overall average length of stay was 21 days (range, 7-59 days). In conclusion, CABG-OLT procedure appears to be safe and effective in the population of patients with advanced CAD and liver disease. In this series, patients appear to benefit from multidisciplinary preoperative evaluation, coordination between cardiac and transplant surgeons, careful graft selection, and use of sapheno-atrial veno-veno bypass.

Abstract
Non-heart-beating donors (NHBD) represent an option to expand the organ supply with good results. We report a donor patient with a left ventricular assist device (LVAD) due to dilated cardiomyopathy in which controlled NHBD was performed. Due to the LVAD, a modified procurement technique was utilized. The liver and kidneys were procured and successfully transplanted. Patients and grafts are alive and well. Successful organ retrieval can be achieved on selected cases of NHBD with LVADs in which modifications of the procurement technique are implemented without jeopardizing the procurement and not increasing preservation injury.

Abstract
BACKGROUND Cavaplasty orthotopic liver transplantation (OLT) offers advantages for hepatectomy and implantation and eliminates the risk of outflow obstruction. However, it does require clamping of the cava. This study describes the use of a vasopressor without fluid expansion or venovenous bypass (VB) for hemodynamic control during the anhepatic phase. METHODS The cavaplasty OLT technique was used routinely. A vasopressor was administered if the mean arterial blood pressure (MAP) was less than 60 mm Hg after clamping of the cava. If the MAP did not reach 60 mm Hg after adjusting the dosage of the vasopressor, femoro-axillary VB would be used. VB was also indicated for preexisting cardiac disease or for massive hemorrhage from severe portal hypertension and extensive adhesions. RESULTS Among all the 121 adult cavaplasty OLTs, 33 were supported with VB and 50 received a vasopressor. The remaining 38 were excluded. However, baseline variables were well matched, except that preexisting cardiac disease was more frequent in the VB group. The median dosage of epinephrine was 0.07 microg/kg/min (range 0.01-0.6). The VB and vasopressor groups were similar in the reduction in mean MAP and the accumulation in arterial lactate upon clamping as well as in the central venous pressure upon unclamping. Postreperfusion hypotension was more frequent in the VB than in the vasopressor group (27.3% vs. 4.0%, P=0.006). There was no primary graft nonfunction or intraoperative right heart failure. One patient in the vasopressor group required postoperative temporary dialysis. Ninety-day patient and graft survival for the VB and vasopressor groups were 97.0% vs. 98.0% and 97.0% vs. 94.0%, respectively. CONCLUSION Modest doses of vasopressor without volume expansion or VB can maintain hemodynamic stability during the anhepatic phase of cavaplasty OLT.
