Abstract
UNLABELLED The piggyback technique (PT) is being used more frequently than caval interposition (CI) in adult orthotopic liver transplants (OLT). It is unclear whether PT alters venous return compared with CI, therefore leading to postoperative complications. The aim of our study was to analyze our experience with PT and CI by comparing ultrasound results of hepatic vein flow on the first postoperative day. PATIENTS AND METHODS This retrospective analysis of consecutive OLTs performed between 2002 and 2005 included data from a single blinded radiologist who reviewed all postoperative day 1 ultrasound examinations. The hepatic vein waveforms were scored as all phasic, all flat, or partially phasic/flat. RESULTS During the study period, we performed, 465 OLT among which 270 had available ultrasound examinations. The etiologies of liver disease were similar between the PT and CI cohorts, hepatitis C and alcoholic liver disease accounted for more than 60%. Two hundred eight (77%) had undergone PT and 62 (23%) CI. Among the PT, 60% were phasic, 31.1% were partially phasic/flat, and 8% were flat. When a CI was performed, 56.5% were phasic, 35.5% were partially phasic/flat, and 8% were flat. CONCLUSIONS There was no significant difference between PT and CI with regard to an effect on hepatic vein waveforms on the first operative day. Therefore, there do not appear to be early hemodynamic benefits of performing CI versus PT anastamoses of OLTs. Further studies may be needed to determine whether long-term sequelae follow the piggyback technique.

Abstract
INTRODUCTION We compared early results of orthotopic liver transplantation (OLT) in adults using the classic versus piggyback technique of inferior vena cava anastomosis. PATIENTS AND METHODS We analyzed 100 consecutive patients who underwent OLT from 2000 to 2003. Group A included 50 patients operated with the classic technique with venovenous extracorporeal bypass, and group B, 50 patients with the piggyback technique. The age range of the patients in group A was 21 to 63 years (mean, 43.5 years) and in group B, 20 to 65 years (mean, 46 years). The gender F/M distribution in group A was 24/26 and in group B, 28/22. The indications for OLT were acute hepatic failure (8%), chronic liver insufficiency (77%), liver tumors (8%), metabolic diseases (5%), and Budd-Chiari syndrome (2%). The degrees of liver insufficiency evaluated according to the Child classification were A, 18; B, 52; and C, 30 patients. The urgency for OLT on the United Network for Organ Sharing (UNOS) scale was UNOS 1-group A, 2 patients; group B, 7 patients; UNOS 2a-group A, 7 patients; group B, 6 patients; UNOS 2b-group A, 29 patients; group B, 30 patients; UNOS 3-group A, 12 patients; group B, 7 patients. RESULTS The average cold ischemia time in group A was 530 minutes and in group B, 515 minutes. The average results on the 10th postoperative day: aspartate transaminase (AST)-group A, 52.5 U/L; group B, 54.5 U/L; alanine transaminase (ALT)-group A, 131.5 U/L; group B, 153 U/L; gamma glutyl transpeptidase (GGTP)-group A, 299 U/L; group B, 285.5 U/L; alkaline phosphatase (ALP)-group A, 164 U/L; group B, 150.5 U/L; bilirubin-group A, 4.37 mg%; group B, 2.71 mg%; activated partial thromboplastin time (APTT)-group A, 37.6 seconds; group B, 34.8 seconds; platelets (PLT)-group A, 167 10(2)/mm(2); group B, 171 10(2)/mm(2). The incidence of postoperative complications was 36% in group A; it was 30% in group B. The mean hospitalization times in the surgical department were 17 days in group A and 16 days in group B. CONCLUSIONS The early results, morbidity and mortality with both applied techniques were similar. Individualization in qualifying the patients for a given operative technique is important. The lower complication rate and reduced treatment cost of the piggyback technique group suggested advantages of this technique when compared with the classical OLT technique.

Abstract
The "piggyback" technique for liver transplantation has gained worldwide acceptance. Still, complications such as outflow obstruction have been observed, usually attributable to technical errors such as small-caliber anastomosis of the suprahepatic vena cava, twisting, or kinking. Iatrogenic Budd-Chiari syndrome after piggyback liver transplantation has been reported as a consequence of obstruction involving the entire anastomosis (usually the 3 hepatic veins). Here we describe technical issues, clinical presentation, diagnosis, and treatment of 3 cases in which outflow obstruction affected only the right hepatic vein. In conclusion, all 3 patients developed recurrent ascites requiring angioplasty and/or stent placement across the right hepatic vein to alleviate the symptoms.

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
Impact of intraoperative blood salvage autotransfusion (IBSA) on neoplastic recurrence. during liver transplantations for hepatocellular carcinoma (LT-HCC). Between January 1989 and February 2003, 16 patients received a LT-HCC without IBSA. This group was compared with 31 patients who received the same surgical procedure during the same period, but with IBSA. Data were prospectively collected. All patients had at least a 1-year postoperative follow up. Pairing was made according to the size of the largest nodule. The percentage of recurrence observed in the two groups was similar: 6.4% in the IBSA group vs. 6.3% in the group without IBSA. The median amount of transfused salvage blood was 1558 ml. The differences observed between the two groups concerned the Child score which was A in 58% patients of the IBSA group vs. 80% in the other group; the percentage of severe portal hypertension was 55% in the IBSA group vs. 31%; the median number of packed red blood cell units transfused intraoperatively was 7 in the IBSA group vs. 0, and the median number of frozen fresh plasma units transfused intraoperatively was 11 in the IBSA group vs. 4.5. It appears that IBSA, essentially used during the most haemorrhagic transplantations, could be used in the case of HCC because it does not modify the risk of neoplastic recurrence.

Abstract
Despite satisfactory overall results reported, early post-operative period after liver transplantation (LT) still represents a critical time with persistently high rate of graft loss. We retrospectively reviewed our experience of 17 yr in LT, analysing the impact on grafts and patient survivals of the acute complications affecting the graft in the early period following LT. To evaluate the changes that occurred over the years in case of early acute graft failure (EAGF), the study population was divided into three equal groups of 223 patients corresponding to three different periods. Ninety (13.5%) experienced an EAGF. Causes of EAGF were hepatic artery thrombosis (HAT) in 32 cases (4.8%), primary graft non-function in 29 cases (4.3%), caval stenosis in 19 (2.8%), early irreversible acute rejection in 6 (0.9%) and portal vein thrombosis in 4 (0.6%). The use of elderly donors and the introduction of the piggyback technique proved to be associated with a higher incidence of HAT and caval stenosis, respectively. Female recipients of male donors were independently associated with Primary graft non-function. Of 90 patients with EAGF, 20 (22.2%) died within the first month after LT, 34 (37.8%) underwent retransplantation (ReLT) and 36 (40%) received conservative treatment. Conservative treatments increased from 3.6% in the first group to 47.0 and 66.8% in the second and third one (p = 0.000). One-year graft and patient survival of patients with EAGF significantly improved over the three eras analysed. The incidence of EAGF remains consistent. Nevertheless, a better understanding of the clinical situations and changes in treatment strategies have led to significant improvements in terms of graft and patient survival rates, now close to the survival rate of EAGF-free patients.

Abstract
Caval anastomosis in liver transplantation has been modified to avoid outflow complications. Classic cava replacement is rarely indicated; most liver transplantation teams use a piggy-back (PB) technique. At the start of our liver transplantation program, we opted for a latero-lateral (L-L) caval anastomosis. In our prospective experience, the L-L caval anastamosis was safe and feasible in all 24 adult patients. No vascular complications occurred. Graft and patient survival rates were both 96% at 11 months follow-up.

Abstract
The ideal method of venous outflow reconstruction with the piggyback technique (PB) in orthotopic liver transplantation (OLT) is not well-established. The complications related to PB in 431 primary OLTs were analyzed comparing the orifices used for the anastomosis (cuff of the recipient left and middle hepatic veins [LM], LM with a >1 cm cavoplasty [LM+], or also including the right hepatic vein [LMR]). Treatment strategies and outcome were also evaluated. Twenty patients (4.6%) experienced complications: 13 of 120 (10.8%) with LM, four of 225 (1.8%) with LM+, and three of 86 (3.5%) with LMR (LM versus LM+: P < 0.0001; LM versus LMR: P = NS; LM+ versus LMR = NS). Balloon dilation was successful in 10 of 13 cases in which it was attempted (77%). Eight patients required retransplantation (40%). Three patients (0.7%) died from causes linked to stenosis. Five-year survival of patients with and without complications was 75% and 79%, respectively (P =NS); 5-year graft survival was 50% and 76%, respectively (P = 0.001). The stump formed by the recipient left and middle hepatic veins with a transversal incision >1 cm of the caval wall constantly provides an adequate width for the caval anastomosis with the PB.

Abstract
PURPOSE To evaluate retrospectively the endovascular management of hepatic venous outflow obstruction after piggyback orthotopic liver transplantation. MATERIALS AND METHODS The study was performed with the approval and under the guidelines of the institutional review board and complied with the Health Insurance Portability and Accountability Act. Informed consent from patients was not required by the institutional review board for this retrospective study. From 1995 to 2003, 13 patients (eight male, five female), including 12 adults and one adolescent (age range, 14-67 years; median age, 52 years), underwent endovascular treatment of hepatic venous outflow obstruction after piggyback orthotopic liver transplantation. Patients gave informed consent for all procedures. Eleven patients received whole livers, and two received living-related donor right liver lobes. Four underwent repeat piggyback orthotopic liver transplantation prior to intervention. Primary stent placement was performed in 12 patients. One patient refused primary stent placement and chose venoplasty alone, but required a stent 5 months later. Short balloon-expandable stents (mean diameter, 14.6 mm +/- 1.1 [standard deviation]) were used to minimize jailing of branch vessels and to resist recoil. Pre- and post-procedural pressure gradients were measured. Follow-up included venography, cross-sectional imaging, and laboratory tests. The Wilcoxon signed rank test or the sign test was performed to compare pre- and post-procedural pressure gradients, body weights, and laboratory values. RESULTS Technical success (pressure gradient < or = 3 mm Hg) was achieved in 13 of 13 patients, and clinical success, in 12 of 13. Mean pre- and post-procedural pressure gradients were 13.0 mm Hg +/- 1.4 and 0.8 mm Hg +/- 0.3. Mean interval from transplantation to intervention was 348 days +/- 159. Mean follow-up was 678 days (range, 16-2880 days). Technical success did not result in clinical improvement in one patient. Biopsy demonstrated severe hepatic necrosis, likely from prolonged venous congestion, and the patient required repeat transplantation. Only one patient required reintervention for stent migration, and no other complications occurred. No significant restenosis was encountered after stent placement. CONCLUSION Hepatic venous outflow obstruction is an uncommon but potentially fatal complication of piggyback orthotopic liver transplantation. Endovascular treatment with balloon-expandable stents is effective, safe, and apparently durable.

Abstract
INTRODUCTION We evaluated the peri- and postoperative effects of the lack of a temporary portocaval anastomosis (TPCA) during orthotopic liver transplantation (OLT) in 84 patients with cirrhosis. PATIENTS AND METHODS From December 1996 to December 2002, 156 liver transplant recipients included (54%; 60 men and 24 women) of mean age 52 +/- 9 years with portal hypertension. In whom peri- and postoperative data were analyzed. RESULTS The median fall in mean arterial pressure upon vascular clamping and unclampings was 20 mm Hg (range 15 to 75), while the median duration of portal vein clamping was 77 minutes. The median amount of blood autotransfusion was 1100 mL (range 0 to 5400). The median number of red blood cell and fresh-frozen plasma units transfused were 5 and 6.5, respectively. The median intraoperative urinary output was 72 mL/h (range 11 to 221). Three patients (3.5%) presented a perioperative complication, but no perioperative death was observed. Six patients experienced an early postoperative complication (<10 days): five hemodynamic complications and one transient renal failure, which did not require hemodialysis. One patient (1%) died at 12 hours after OLT from acute pulmonary edema. CONCLUSION This study shows that systematic TPCA during OLT with preservation of the native retrohepatic vena cava in cirrhotic patients does not appear to be justified. In contrast, peri- and postoperative hemodynamic parameters as well as blood component requirements were comparable to those of the literature reporting OLT with straightforward TPCA.

Abstract
The aim of this study is to analyse a single centre's experience with two techniques of liver transplantation (OLT), conventional (CON-OLT) and piggyback (PB-ES), and to compare outcome in terms of survival, morbidity, mortality and post-operative liver function as well as operative characteristics. A consecutive series (1994-2000) of 167 adult primary OLT were analysed. Ninety-six patients had CON-OLT and 71 patients had PB-ES. In PB-ES group two revascularization protocols were used. In the first protocol reperfusion of the graft was performed first via the portal vein followed by the arterial anastomosis (PB-seq). In the second protocol the graft was reperfused simultaneously via portal vein and hepatic artery (PB-sim). One-, 3- and 5-yr patient survival in the CON-OLT and PB-ES groups were 90, 83 and 80%, and 83, 78 and 78%, respectively (p = ns). Graft survival at the same time points was 81, 73 and 69%, and 78, 69 and 65%, respectively (p = ns). Apart from the higher number of patients with cholangitis and sepsis in CON-OLT group, morbidity, retransplantation rate and post-operative liver and kidney function were not different between the two groups. The total operation time was not different between both groups (9.4 h in PB-ES vs. 10.0 h in CON-OLT), but in PB-ES group cold and warm ischaemia time (CIT and WIT), revascularization time (REVT), functional and anatomic anhepatic phases (FAHP and AAHP) were significantly shorter (8.9 h vs. 10.7 h, 54 min vs. 63 min, 82 min vs. 114 min, 118 min vs. 160 min and 87 min vs. 114 min, respectively, p < 0.05). RBC use in the PB-ES group was lower compared to the CON-OLT group (4.0 min vs. 10.0 units, p < 0.05). Except for WIT and REVT there were no differences in operative characteristics between PB-Sim and PB-Seq groups. The WIT was significantly longer in PB-Sim group compared with PB-Seq group (64 min vs. 50 min, p < 0.05); however REVT was significantly shorter in PB-Sim group (64 min vs. 97 min, p < 0.05). Results of this study show that both techniques are comparable in survival and morbidity; however PB-ES results in shorter AAHP, FAHP, REVT and WIT as well as less RBC use. In the PB-ES group there seems to be no advantage for any of the revascularization protocols.

Abstract
The incidence of hepatic venous stenosis is higher in partial liver transplantation. New methods for hepatic venous reconstruction in left liver transplantation, which secure wide anastomosis, were devised and are reported here. In the graft, the right side of the middle hepatic vein or the left side of the left hepatic vein was cut longitudinally and a rectangular-shaped vein patch was attached for venoplasty. In the recipient, after the left and middle hepatic veins were joined, the right side of the middle hepatic vein was cut toward the closed right hepatic vein, making a horizontal cavotomy for anastomosis. Of 92 patients who underwent conventional hepatic vein reconstruction, 3 were complicated by hepatic venous stenosis (median follow-up 43 months). By contrast, there were no hepatic vein complications in the 20 patients who underwent the new technique (7 months). The current method appears to be technically feasible for outflow reconstruction in left liver graft transplantation.

Abstract
The liver transplantation technique advances have allowed the endovascular treatment of stenosis between hepatic vein and inferior vena cava, and this has become an established and widely acceptable method for the treatment of patients with end-stage liver disease. However, in spite of the advances in the surgical technique of liver transplantation there is relatively still a high incidence of postoperative complications, especially those related to vascular complications. One technical variant of orthotopic liver transplantation is the piggyback technique with conservation of the recipient vena cava, which is anastomosed to the graft hepatic veins. As a consequence of the increased number of liver transplants in children, there is a higher demand for endovascular treatment of vascular stenosis, such as those at the level of the hepatic veins. This leads to more consistent experience of endovascular treatment of the surgical vascular complications following liver transplantation. This article describes the case of a child submitted to liver transplantation with reduced graft (left lateral segment) who presented stenosis of the anastomosis between the hepatic vein and IVC 6 months later which was successfully treated by PTA.

Abstract
The incidence of hepatic venous complications in partial liver transplantation is more frequent than that in whole liver transplantation. There are no reports of a surgical strategy for hepatic venous outflow block (HVOB) after living-donor liver transplantation. HVOB was diagnosed when the pull-through pressure gradient across the anastomotic site was over 5 mm Hg. Reoperation for venous anastomosis was performed if the angioplasty was unsuccessful. After dissection around the hepatic venous anastomotic site, a patch venoplasty of the anastomosis was performed. When the inferior vena cava was constricted, venoatrial anastomosis was performed. In 6 years, 5 of 223 patients experienced HVOB. Balloon angioplasty was successfully performed in two patients, a patch venoplasty of the anastomosis in two, and venoatrial anastomosis in one. In all patients, the ascites stopped. HVOB must be diagnosed as soon as possible with Doppler ultrasound and venography. Prompt surgical revision can salvage the grafts.

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.

Abstract
The radiologist can play a key role in diagnosis and management of many of the infectious, inflammatory, and neoplastic processes that affect patients after liver transplantation. Familiarity and skill with the full range of diagnostic and interventional tools are essential for radiologists dealing with transplant patients, even outside the medical centers where the transplantation takes place.

Abstract
Pulmonary embolism (PE) is a well known and serious complication that may develop after abdominal surgery. Liver transplant recipients are not immune to PE and tend to share many of the same risk factors with surgical patients who are stricken with this potential fatal complication. Liver transplantation using the piggyback (PB) technique is widely accepted, although there are reports of technique-specific-related vascular complications. We present a case of a 49-yr-old male liver transplant recipient who received his graft using the PB while simultaneously undergoing aortic valve replacement. His post-operative course was complicated by a PE 15 d after his surgery and was the result of an intracaval thrombus of the graft liver. The current case should alert clinicians to think of a donor intracaval thrombus as a complication of PB liver transplantation and a possible source of PE.

Abstract
BACKGROUND The original method of liver transplantation (LT) included recipient inferior vena cava (IVC) resection and the use of extracorporeal venovenous bypass (VVB). Refinements in technique permit transplantation to be done with IVC preservation and without VVB use. MATERIAL AND METHODS Between November 1993 and November 2000, 202 consecutive grafts were performed in 188 adults (>/=16 years of age). Twelve patients (6.4%) received two and three retransplants (re-LT). Split grafting was performed 19 times (19 of 202 grafts, 9.4%). Risk factors included United Network of Organ Sharing status I (n=30, 16%), previous right upper abdominal surgery (n=32, 17.1%), caudate lobe encirclement of IVC (n=65, 32.2%), IVC (n=24, 11.9%), and splanchnic venous modification (n=58, 30.9%), transjugular intrahepatic portosystemic stent shunt (n=34, 16.8%), giant (>5 kg) liver tumor (n=6, 3%), septic necrosis of the caudate lobe (n=1, 0.5%), and previous cavocaval (n=13, 6.4%) or classical LT (n=5, 2.5%). RESULTS IVC preservation, avoidance of IVC cross clamping and of VVB use were possible in 98.9%, 93%, and 99.5% of 183 primary LT and in 89.5%, 84.2%, and 89.5% of 19 re-LT. Temporary portocaval shunting was never applied. Perioperative mortality was 1.2%. There was no allotransfusion in 73 (36%) grafts and 45 (22%) patients were immediately extubated. Permanent hepatic vein and caval problems were encountered in three (1.5%) grafts. One patient needed stent placement to treat IVC stenosis. Actual 3- and 12-month patient survival for whole, re-LT, and right-lobe split LT groups were 94.7%, 94.1%, 94.7%, 88.2%, 94.1%, and 89%. Three-month graft survival rates for these groups were 92.6%, 94.7%, and 84.2%. CONCLUSIONS LT with IVC preservation and without VVB use and portocaval shunting is possible in nearly all primary transplants and in the majority of re-LT.

Abstract
Delayed-onset fibrotic stenosis of the hepatic-vein anastomosis following liver transplantation resulted in ascites and abnormal liver-function tests. The stenosis was treated with balloon dilatation resulting in a clinical improvement; however, this had to be repeated four times in the 9 months after transplantation due to recurrent stenosis. The stenosis was eventually successfully treated with percutaneous insertion of a metal stent. Aspirin 50 mg daily was prescribed for 1 month. The patient was not anticoagulated. The patient remains clinically well at follow up after 18 months.

Abstract
As promoters of orthotopic liver transplantation (OLT) with preservation of caval flow, we reviewed our 8-year experience to assess the feasibility and limits of this technique. Preservation of caval flow during OLT, which improves intraoperative hemodynamic stability, was not considered feasible in a significant proportion of transplant recipients. When transient clamping of caval flow is required, causes and consequences of this clamping during all phases of the procedure were not reported. Between 1991 and 1998, a total of 275 OLTs using a whole graft were performed in 259 patients with a policy consisting of a systematic attempt to preserve inferior vena cava (IVC) and caval flow. Preservation of IVC flow was possible in all cases, and no procedure was converted to the conventional technique. Caval flow was maintained throughout the procedure in 246 procedures (90%). Temporary IVC cross-clamping was required in 24 cases during hepatectomy because of difficult dissection and in 5 cases after graft reperfusion because of outflow obstruction; none required the use of a venovenous shunt. IVC cross-clamping during hepatectomy was required more frequently in cases of a large liver, with a mean duration of 11 +/- 4 minutes, but without significant influence on early postoperative risk, including one graft failure (4%) and one postoperative death (4%). Conversely, IVC cross-clamping after reperfusion, with a mean duration of 23 +/- 5 minutes, was associated with four graft failures (80%) and four deaths (80%). We conclude that IVC preservation is feasible in almost all candidates, allowing the use of split livers from cadaveric or living donors independently from their underlying disease. Although preservation of caval flow was possible in the large majority of cases, transient IVC cross-clamping during hepatectomy was well tolerated in contrast to caval clamping after graft reperfusion. Therefore, if necessary, we recommend transient IVC cross-clamping to perform a large cavocaval anastomosis.

Abstract
BACKGROUND We first introduced the orthotopic liver transplantation utilizing cavaplasty technique in 1994. This paper describes the surgical technique and assesses the outcome of the cavaplasty OLT. METHODS The cavaplasty procedure was used in 115 consecutive orthotopic liver transplantations, including six left lateral and two right lobe transplantations, between November 1994 and September 2000. Fifty-three (66.3%) transplantations required femoro-axillary veno-venous bypass in the initial 4 years, whereas only eight (22.9%) needed VB in the subsequent 2 years. Conversion to piggyback or standard technique was not necessary in any patient. RESULTS Median results are as follows: operative time 4.5 hr, warm ischemia time 25 min, and blood transfused (packed red blood cells) 6 units. These findings did not differ between first transplantation and retransplantation. There were no perioperative deaths related to the cavaplasty technique. No hepatic venous outflow obstruction was observed, including living-related OLTs. No patient required postoperative hemodialysis for acute renal failure. The median intensive care and hospital stays were 2 days and 10 days, respectively. CONCLUSIONS The cavaplasty technique requires no retrocaval, hepatic vein, or short hepatic vein dissection, and the inferior vena cava can be preserved, which provides advantages for hepatectomy and easy hemostasis, especially during retransplantation. The wide-open triangular caval anastomosis is easy to perform, allowing short implantation time and size matching and avoiding outflow obstruction. The short implantation time reduces the need for veno-venous bypass. Our experience indicates that the cavaplasty technique can be applied to all patients and is justified by minimal technical complications.

Abstract
Orthotopic liver transplantation has become the treatment of choice for patients with end-stage nonmalignant liver disease. The surgical techniques and immunosuppressive therapy for this procedure have improved considerably. Nevertheless, there are still significant complications, particularly those of vascular origin, which can lead to graft failure and require retransplantation unless prompt treatment is instituted. These complications include arterial and venous thrombosis and stenosis; arterial pseudoaneurysm; biliary leakage, stricture, and obstruction; liver ischemia, infarction, and abscess; fluid collections and hematomas; lymphoproliferative disorders; recurrent tumors; hepatitis C virus infection; and splenic infarction. Since the clinical presentation of posttransplantation complications is frequently nonspecific and varies widely, imaging studies are critical for early diagnosis. Helical computed tomography (CT) is a valuable complement to ultrasonography (US) in the postoperative period and is a safe, accurate, and noninvasive method of demonstrating hepatic vessels (hepatic artery, portal vein, hepatic veins, and inferior vena cava) and evaluating nonvascular complications (in the hepatic parenchyma and bile duct abnormalities) and extrahepatic tissues. Knowledge and early recognition of these complications is essential for graft salvage, and CT can provide valuable information, particularly for patients with indeterminate US results or in whom US examination is difficult.

Abstract
The aim of this study is to establish the incidence of serious morbidity and mortality associated with the placement of large-bore (18 to 20 F) percutaneous bypass cannulae for venovenous bypass (VVBP) during orthotopic liver transplantation (OLT). This technique has been reported to be rapid, simple, and safe. We reviewed the case notes of 312 patients who underwent OLT in our center using this technique. We describe 4 cases of serious morbidity (incidence, 1.28%) and 1 death (incidence, 0.32%) related directly to percutaneous placement of the bypass cannula. We conclude that percutaneous cannula placement for VVBP during OLT has the potential for life-threatening complications, and this must be considered when electing to use this technique. When percutaneous cannulae are to be used, we recommend the use of the right internal jugular vein for return cannulation and the use of ultrasound guidance, particularly in those patients in whom cannulation is predictably difficult.

Abstract
STUDY AIM The aim of this retrospective study was to report an original technique for heterotopic liver transplantation with the graft in the left hypochondrium, and to discuss the indications and limitations of this technique. PATIENTS AND METHOD Over the past ten years, four patients were treated by this technique; this constitutes 2% of all liver transplantations carried out during this period. RESULTS No immediate per- or postoperative mortality related to the surgical procedure was noted. Moreover, no severe hemodynamic complications occurred during the per- or postoperative period. In three out of four cases, hepatic function was fully restored within 48 hours. Long-term survival (50 and 97 months) was observed in two patients. CONCLUSION Heterotopic liver transplantation in the left hypochondrium is an alternative to orthotopic liver transplantation; it is a technique that is easy, non-aggressive, and with good long-term results. It is indicated in cases where the main portal vein is non-functional (following total thrombosis or porto-caval shunt), and orthotopic liver transplantation is therefore not possible.

Abstract
Stenosis of the hepatic vein anastomosis is an unusual but critical complication after liver transplantation. In pediatric liver transplantation, the scarcity of size-matched donors has required the use of segmental liver allografts, either as reduced-size or split-liver grafts. This report illustrates the primary use of a hepatic vein stent to manage hepatic venous outflow obstruction in a pediatric split-liver recipient, and reviews experience in the management of hepatic venous outflow obstruction after liver transplant using stent methods.

Abstract
OBJECTIVE To examine how the choice of surgical technique influenced perioperative outcomes in liver transplantation. SUMMARY BACKGROUND DATA The standard technique of orthotopic liver transplantation with venovenous bypass (VVB) is commonly used to facilitate hemodynamic stability. However, this traditional procedure is associated with unique complications that can be avoided by using the technique of liver resection without caval excision (the piggyback technique). METHODS A prospective comparison of the two procedures was conducted in 90 patients (34 piggyback and 56 with VVB) during a 2.5-year period. Although both groups had similar donor and recipient demographic characteristics, posttransplant outcomes were significantly better for the patients undergoing the piggyback technique. The effect of surgical technique was examined using a stepwise approach that considered its impact on two levels of perioperative and postoperative events. RESULTS The analysis of the first level of perioperative events found that the piggyback procedure resulted in a 50% decrease in the duration of the anhepatic phase. The analysis of the second level of perioperative events found a significant relation between the anhepatic phase and the duration of surgery and between the anhepatic phase and the need for blood replacement. The analysis of the first level of postoperative events found that the intensive care unit stay was significantly related to both the duration of surgery and the need for blood replacement. The intensive care unit stay was in turn related to the second level of postoperative events, namely the length of hospital stay. Finally, total charges were directly related to length of hospital stay. The overall 1-year actuarial patient and graft survival rates were 94% in the piggyback and 96% in the VVB groups, respectively. CONCLUSIONS These data demonstrate that surgical choices in complex procedures such as orthotopic liver transplantation trigger a chain of events that can significantly affect resource utilization. In the current healthcare climate, examination of the sequence of events that follow a specific treatment may provide a more complete framework for choosing between treatment alternatives.
