Abstract
Hepatic artery thrombosis (HAT) is the most serious vascular complication after liver transplantation (LT). Moreover, in comparison to deceased donor liver transplantation (DDLT), hepatic artery (HA) anastomosis is more challenging in living donor liver transplantation (LDLT) with a lot of controversial topics about the use of microscopic surgery. We aimed to compare the use of microscopic and loupe surgery in HA anastomosis in adult and pediatric LDLT to decrease the incidence of vascular complications. We searched PubMed, Scopes, Web of Science, and Cochrane Library for eligible studies from inception to April 2023 and a systematic review and a meta-analysis were done. According to our eligibility criteria, 10 studies with a total of 1939 patients were included. In comparison to microscopic surgery, loupe anastomosis has a similar incidence of HAT (thrombosis, risk ratio (RR) = 0.96, 95% CI = 0.26-3.48, P = 0.95). In addition to that, no significant difference was detected between the two types in terms of stenosis, decreased blood flow and hospital stay (decreased blood flow, RR = 0.68, 95% CI = 0.01-86.65, P = 0.88), (stenosis, RR = 1.81, 95% CI = 0.19-17.21, P = 0.60), (hospital stay, mean deviation (MD) = 1.16, 95% CI = -3.79-6.11, P = 0.65). However, the anastomotic time was longer in the case of microscopic surgery (anastomotic time, MD = 24.09, 95% CI = 7.79-40.39, P = 0.004). With an equal incidence of complications and longer anastomotic time, there is no added benefit of the routine use of microscopic surgery in HA anastomosis in LDLT.

Long-Term Feasibility of Rescue Reconstruction for Isolated Bile Ducts With Using Cystic Duct in Living Donor Liver Transplantation. Transplant Proc 2023; 55:1611-1617. [PMID: 37385837 DOI: 10.1016/j.transproceed.2023.03.086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 03/01/2023] [Accepted: 03/12/2023] [Indexed: 07/01/2023]
Abstract
BACKGROUND The isolated bile duct is sometimes observed in the right liver graft of living donor liver transplantation (LDLT). Even though, as a rescue option, it is known to use the recipient's cystic duct (CyD) for duct-to-duct anastomosis, the long-term feasibility of rescue duct-to-CyD (D-CyD) anastomosis remains unclear. METHODS We prospectively collected data in the right liver-LDLT cohort and compared rescue D-CyD anastomosis (n = 4) with standard duct-to-hepatic duct (D-HD, n = 45) anastomosis (D-CyD group, n = 4). RESULTS The observation period was over 5 years (range, 68-171 mo) after LDLT. The D-CyD group included the following anastomosis procedures: anastomosis between the intrahepatic bile duct of the graft and the CyD of the recipient and anastomosis between the posterior HD and the CyD. Surgical outcomes between the 2 groups are similar, excluding the time for the biliary reconstruction (D-CyD, 116 ± 13 min vs D-HD, 57 ± 3 min). During the period, one recipient in the D-CyD group exhibited postoperative biliary stricture and biliary stone, and 6 recipients underwent those complications in the D-HD group (D-CyD, 25.0% vs D-HD, 13.3%) All recipients in the D-CyD group are presently alive and have not experienced liver dysfunction. CONCLUSIONS Our findings suggest that rescue D-CyD anastomosis for an isolated bile duct in a right liver LDLT is acceptable as a life-saving option in terms of long-term feasibility.

Abstract
BACKGROUND Failure to achieve a good arterial inflow to the graft in living donor liver transplantation (LDLT) has disastrous consequences to the graft and patient survival. Standard microvascular techniques of hepatic artery (HA) anastomosis used in deceased donor liver transplantation are not applicable in LDLT. We present the results of our unique Backwall-first technique of HA anastomosis in both adult and pediatric LDLT. PATIENTS AND METHODS Retrospective review of all consecutive patients who underwent LDLT from January 2010 to December 2020 was performed from our prospective database. Data with regard to early postoperative (90-day) hepatic arterial complications were analyzed. RESULTS A total of 1276 LDLTs (876 adults, 400 children) were performed during the study period. In the 90-day postoperative period, HA anastomotic complications [thrombosis in 11 (0.9%); pseudoaneurysm in 3 (0.2%)] were observed in 14 recipients (1.1%) including 8 adults (0.9%) and 6 children (1.5%). Eight of these 14 recipients (0.6%) including 4 adults (0.5%) and 4 children (1%) had standard HA reconstruction. The remaining six (0.5%) including 4 adults and 2 children had complex arterial reconstruction with interposition graft and/or alternative arterial inflow. CONCLUSION The Backwall-first technique of HA reconstruction described in this study achieved a very low HA complication rate in LDLT.

Abstract
BACKGROUND Hepatic artery reconstruction is an essential part of liver transplantation. This difficult stage of the operation is even more demanding in living donor liver transplantation than in deceased donor liver transplantation. One of the most important advances in hepatic artery reconstruction for living liver grafts was the introduction of microsurgical techniques involving an operative microscope or surgical loupe. Many surgical reconstruction techniques have been used in this field. PURPOSE In this article, first, we will talk about the hepatic artery reconstruction techniques that are frequently used in deceased donor liver transplantation, and afterward, we will talk about the hepatic artery reconstruction techniques used in living donor liver transplantation, which include the hepatic artery reconstruction technique we use and call "one stay corner suture technique". CONCLUSIONS We think high-volume transplant centers should tend to develop a standardized technique for doing hepatic artery reconstruction with their teams. We think the "one stay corner suture technique" can be easily applied in centers that perform LDLT.

Abstract
OBJECTIVES Living donor liver transplant is a complex surgery with well-known complications. Here, we report the use of the right and left hepatic arteries of the recipient for anastomosis and the effects of each procedure on overall outcomes and any associated short-term or long-term biliary complications. MATERIALS AND METHODS This was a prospective observational study with long-term follow-up of 200 patients (100 in the right hepatic artery group and 100 in the left hepatic artery group). RESULTS The average donor age was 28.9 years in the left hepatic artery group and 30.9 years in the right hepatic artery group. Most of the donors (60%) were female. Overall, there was 10.5% mortality in the early postoperative period. Among survivors, there were more late strictures in the right hepatic artery group (29.7% vs 22.7%). Bile leak (P = .42), mortality (P = .71), and incidence of late-onset biliary strictures (P = .83) were less common in the left hepatic artery group. CONCLUSIONS Left artery anastomosis was found to be technically safe and feasible and did not adversely affect patient outcome compared with right artery anastomosis. Left hepatic artery anastomosis may also reduce the incidence of the biliary complications compared with the right hepatic artery anastomosis.

Abstract
BACKGROUND Living donor liver transplantation (LDLT) has expanded the availability of liver transplant but has been associated with early technical complications including the devastating complication of hepatic artery thrombosis (HAT), which has been reported to occur in 14% to 25% of LDLT using standard anastomotic techniques. Microvascular hepatic artery reconstruction (MHAR) has been implemented in an attempt to decrease rates of HAT. The purpose of this study was to review the available literature in LDLT, specifically related to MHAR to determine its impact on rates of posttransplant complications including HAT. METHODS A systematic review was conducted using PubMed/Medline and Web of Science. Case series and reviews describing reports of microscope-assisted hepatic artery anastomosis in adult patients were considered for meta-analysis of factors contributing to HAT. RESULTS In all, 462 abstracts were screened, resulting in 20 studies that were included in the meta-analysis. This analysis included 2,457 patients from eight countries. The pooled rate of HAT was 2.20% with an overall effect size of 0.00906. CONCLUSION Systematic literature review suggests that MHAR during LDLT reduces vascular complications and improves outcomes posttransplant. Microvascular surgeons and transplant surgeons should collaborate when technical challenges such as small vessel size, short donor pedicle, or dissection of the recipient vessel wall are present.

Abstract
PURPOSE Surgical resection is the only curative treatment for pancreatic cancer. Arterial resection and reconstruction during pancreaticoduodenectomy for advanced pancreatic cancer remain controversial due to a high rate of complications. METHODS We report two cases of pancreatic cancer with hepatic artery resection and reconstruction using the right gastroepiploic artery during pancreaticoduodenectomy after neoadjuvant therapy. RESULTS The patients underwent pancreaticoduodenectomy with resection of the right hepatic and common hepatic arteries. Achieving direct anastomosis was difficult; therefore, we planned hepatic artery reconstruction using the right gastroepiploic artery. We performed the reconstruction using an interrupted suture with end-to-end anastomosis. The first patient developed a postoperative pancreatic fistula, while the postoperative course of the second patient was uneventful. However, there were no adverse events related to the arterial reconstruction. R0 resection was achieved, and postoperative computed tomography revealed good patency of the reconstructed artery. CONCLUSION Hepatic artery reconstruction using the right gastroepiploic artery in pancreatic cancer might be technically safe and might become one of the alternative options.

Abstract
Background Reconstruction of the hepatic arterial inflow can be technically demanding in living donor liver transplantation, and thrombosis can result in graft loss and mortality. We describe the safe and reproducible “W” technique to reconstruct the hepatic artery and outcomes before and after adoption of the technique in a consecutive series of liver transplants at 2 high-volume living donor liver transplant centers. Material/Methods Prospectively collected data were analyzed to compare the outcomes before and after introduction of a standardized “W” technique for reconstruction of the hepatic artery in 2 high-volume living donor liver transplant programs. Results In a consecutive series of 675 liver transplants, of which 27 were deceased donor transplants and 648 were living donor transplants, 443 transplants were performed with a standard interrupted reconstruction of the hepatic artery under loupes. These transplants were performed by a single surgeon, with an incidence of hepatic artery thrombosis of 2%. After introduction of the “W” technique, despite the arterial reconstruction being done by several surgeons in the early part of their learning curve, the incidence of hepatic artery thrombosis decreased to 0.86% in the next 232 transplants. Conclusions The “W” technique is a simple, easy to learn and teach technique for reconstruction of the hepatic artery without the use of the operating microscope in living donor liver transplantation.

Abstract
Introduction Because surgical resection with simultaneous hepatic artery (HA) resection and reconstruction for perihilar cholangiocarcinoma (PHC) is technically demanding, the surgical indication for this challenging procedure is controversial. Thus, this study aimed to evaluate the efficacy of simultaneous HA resection and reconstruction for PHC. Methods Between January 2002 and January 2018, 13 patients with PHC underwent surgical intervention with simultaneous resection and reconstruction of the HA at Yamaguchi University Hospital (Ube, Japan) and Osaka University Hospital (Suita, Japan). Results There were 2 cases (15.4%) of 90-day postoperative mortality. Nine patients (69.2%) developed major postoperative complications (Clavien-Dindo classification ≥IIIa). Curative resections (R0) were achieved in 8 cases (61.5%). The median survival time (MST) and 1- and 3-year survival rates after resection (including in-hospital deaths) were 20.9 months and 61.5 and 10.3%, respectively. The MST and 1- and 2-year survival rates of 8 patients who underwent R0 resection were significantly better than those of the other 5 patients (24.2 vs. 10.2 months, 75.0 vs. 40.0%, and 50.0 vs. 0.0%, respectively, p = 0.0228). Conclusions Simultaneous HA resection and reconstruction is technically possible and may provide long-term survival in selected patients with locally advanced PHC.

Abstract
Backgrounds/Aims Hepatic artery (HA) reconstruction during living donor liver transplantation (LDLT) has been performed by experienced microsurgeons with operative microscope in most centers. However, it takes long time to learn the skills and so, to simplify this procedure, transplant surgeons recently performed this procedure using surgical loupe. Methods This study retrospectively reviewed outcomes of 237 LDLTs at our institution from January 2012 to October 2016. In group I, HA reconstruction was performed under operative microscope by an experienced microsurgeon and in group II, it was performed using surgical loupe by a transplant surgeon with little experience for arterial anastomosis. Results There was no difference in most perioperative outcomes between two groups except mean time required for HA reconstruction (24.2±4.3 vs. 20.9±6.9 minutes, p=0.001). Multivariable regression modeling to adjust for baseline differences showed that the use of surgical loupe was not associated with either HA thrombosis or intraoperative HA revision rate. Conclusions HA reconstruction under surgical loupe can be performed simply and yields results as good as with operative microscopy, even when the transplant surgeon has less experience with HA anastomosis.

Abstract
AIM Hepatic artery thrombosis is one of the major complications affecting patient and graft survival after liver transplantation. In this study, we analyzed the factors affecting the development of early hepatic artery thrombosis (eHAT) and its outcomes in pediatric liver transplantation. METHODS A total of 175 pediatric patients underwent living donor liver transplantation between January 2013 and November 2018. Factors affecting eHAT and its outcomes were examined. RESULTS Nine patients (5.1%) developed eHAT. In multivariate analysis, intraoperative hepatic artery revision and Roux-en-Y hepaticojejunostomy biliary reconstruction type were statistically significant (all, P < .05). Thrombectomy and reanastomosis was performed in 5 patients. Two of them were successful. In total, 3 retransplantations were performed and all of those patients are still alive. CONCLUSION The factors affecting eHAT are still a matter of debate. Intraoperative hepatic artery anastomosis revision and Roux-en-Y hepaticojejunostomy reconstruction were independent risk factors for development of eHAT. In the present study, the confidence interval of the variables is high, therefore exact determination of the risk factors may not be possible. Early detection and thrombectomy and reanastomosis may be the first treatment of choice to rescue the patient and graft. When it fails, retransplantation must be an alternative. The results of the present study state that at least once a day the vascular anastomosis must be examined by Doppler ultrasonography in the post-transplant first week. It must be repeated when liver enzymes increase. The patients under high risk for eHAT may be followed up closer.

Abstract
Background The immediate challenges during microvascular reconstruction of hepatic artery (HAR) during liver transplantation (LT) can be many. Hence, in order to give a cross sectional view of these problems this study over a period of 1 year, showing our routine practice, was taken up. Methods From January 2015 to December 2015, a total of 133 LTs were performed in Kaohsiung Chang Gung Memorial Hospital, Taiwan. All hepatic artery (HA) reconstructions were performed by a microvascular surgeon under an operating microscope. Results In the 133 patients, one artery was anastomosed in 123 (92.5%) patients, two in 9 (6.8%) patients and three in 1 (0.7%) of the patient. Eleven (8.3%) arteries were less than 2 mm in size (1-1.9 mm). There were intimal dissections (IDs) involving either the donor or the recipient arteries of mild to severe nature in 9 (6.8%) patients. Immediately following graft arterial anastomosis, either there was no flow or an intraoperative hepatic artery thrombosis (HAT) was found in nine (7.1%-8 LDLT, 4.8%-1 DDLT) patients. Immediate re-do anastomosis was done in all of these patients who did well in the follow-up. The overall post-operative success rate was 99.2%. One patient (0.8%) developed postoperative HAT due to infection during follow up and died due to sepsis. Conclusions Small vessels or HA injury are the frequently encountered problems by a micro vascular surgeon. The other problems could be ID, need to do multiple reconstructions, immediate HAT and ability to re-do the HAR immediately.

Liver Transpl 2017; 23:887-898. [PMID: 28422392 DOI: 10.1002/lt.24775] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Revised: 04/09/2017] [Accepted: 04/13/2017] [Indexed: 12/17/2022]
Abstract
The reconstruction of the hepatic artery (HA) is the most complex step in living donor liver transplantation (LDLT) because of the smaller diameter of the artery and the increased risk of HA-related complications. Because of the smaller diameter of the HA, many centers use a microsurgical technique with interrupted sutures for arterial anastomosis. The aim of our study was to retrospectively investigate the outcomes after HA reconstruction performed under magnifying loupes using the "parachute technique." From August 1, 2002 to August 31, 2016, LDLT was performed in 766 recipients. HA reconstruction for the initial 25 LDLT surgeries was performed using a microsurgery technique (era 1). From May 2007 until the end date, HA reconstruction was performed in 741 recipients by a "parachute technique" under surgical loupes (era 2). HA reconstruction was performed using surgical loupes in 737 adults (male:female, 526:211) and 4 pediatric patients (male:female, 3:1). The average diameter of the donor graft HA was 2.8 mm (range, 1-6.5 mm). The most notable factor in this era was the quick HA anastomosis procedure with a mean time of 10 ± 5 minutes (range, 5-30 minutes). In era 2, 9 (1.21%) patients developed hepatic artery thrombosis (HAT), whereas 2 patients developed nonthrombotic HA-related complications. Extra-anatomic HA reconstruction was performed in 14 patients due to either primary HA anastomosis failure or a poor caliber recipient HA. The use of magnifying surgical loupes to perform HA reconstruction is safe, feasible, and yields a low incidence of HA-related complications. The "parachute technique" for HA reconstruction can achieve a speedy reconstruction without increasing the risk of HAT. Liver Transplantation 23 887-898 2017 AASLD.

Abstract
BACKGROUND Despite the technical and medical improvements in the recent years, hepatic artery thrombosis (HAT) remains a devastating complication after living donor liver transplantation (LDLT). We described our surgical techniques and monitoring protocols for hepatic artery reconstruction. We reported one of the lowest incidence rates of HAT in the literature. METHODS Between 2008 and 2015, a total of 325 LDLTs performed at our institute were retrospectively analyzed. Under microscope assistance, all hepatic artery anastomosis were performed in a risk-free and back-wall first manner. We collected donors' and recipients' demographics, operative procedures, and outcome. RESULTS A total of 325 adult LDLTs were enrolled in the study. Of these, 297(91.4%) were right liver graft. The mean diameter of the hepatic arteries of the graft was 1.9 ± 0.3 mm. A single HA anastomosis was performed in 310 patients (95.4%). The 1-, 3-, and 5-year overall patient survival rates were 84.8%, 76.8%, and 75.2%, respectively. Only one (0.3%) episode of HAT was encountered in our series. The patient was treated successfully with nonsurgical management. CONCLUSION Our study showed that the occurrence of HAT is avoidable. Identifying risk factors associated with HAT, meticulous surgical techniques, and careful routine flow monitoring are mandatory to avoid disastrous complications.

Abstract
Adult-to-adult living donor liver transplantation (LDLT) is widely accepted today with good outcomes and safety reported worldwide for both donor and recipient. Nonetheless, it remained a highly demanding technical and complex surgery if undertaken. The last two decades have seen an increased in adult-to-adult LDLT following our first report of right lobe LDLT in overcoming graft size limitation in adults. In this article, we discussed the operative techniques and challenges of adult right lobe LDLT incorporating the middle hepatic vein, which is practiced in our center for the recipient operation. The various issues and challenges faced by the transplant surgeon in ensuring good recipient outcome are explored and discussed here as well. Hence, it is important to understand that a successful recipient operation is dependent of multifactorial events starting at the preoperative stage of planning, understanding the intraoperative technical challenges and the physiology of flow modulation that goes hand-in-hand with the operation. Therefore, one needs to arm oneself with all the possible knowledge in overcoming these technical challenges and the ability to be flexible and adaptable during LDLT by tailoring the needs of each patient individually.

Abstract
OBJECTIVES Hepatic arterial (HA) and portal venous (PV) complications of recipients after living donor liver transplantation(LDLT) result in patient loss. The aim of this study was to analyze these complications. METHODS We retrospectively analyzed HA and/or PV complications in 213 of 222 recipients underwent LDLT in our centre. The overall male/female and adult/pediatric ratios were 183/30 and 186/27 respectively. RESULTS The overall incidence of HA and/or PV complications was 19.7% (n = 42), while adult and pediatric complications were 18.3% (n = 39) and 1.4% (n = 3) respectively. However early (<1month) and late (>1month) complications were 9.4% (n = 20) and 10.3% (n = 22) respectively. Individually HA problems (HA stenosis, HA thrombosis, injury and arterial steal syndrome) 15% (n = 32), PV problems (PV thrombosis and PV stenosis) 2.8% (n = 6) and simultaneous HA and PV problems 1.9% (n = 4). 40/42 of complications were managed by angiography (n = 18), surgery (n = 10) or medically (Anticoagulant and/or thrombolytic) (n = 12) where successful treatment occurred in 18 patients. 13/42 (31%) of patients died as a direct result of these complications. Preoperative PVT was significant predictor of these complications in univariate analysis. The 6-month, 1-, 3-, 5- 7- and 10-year survival rates in patients were 65.3%, 61.5%, 55.9%, 55.4%, 54.5% and 54.5% respectively. CONCLUSION HA and/or PV complications specially early ones lead to significant poor outcome after LDLT, so proper dealing with the risk factors like pre LT PVT (I.e. More intensive anticoagulation therapy) and the effective management of these complications are mandatory for improving outcome.

Abstract
Small-for-size graft syndrome is an inevitable complication in living donor liver transplantation (LDLT). We hypothesized that graft weight (GW) measured after graft procurement is one of the variables predicting postoperative graft function. A total of 138 consecutive recipients of adult-to-adult LDLT between March 1999 and October 2014 were included in this study. We investigated the factors associated with small-for-size-associated graft loss (SAGL) to determine the GW required for each patient. Both preoperatively assessed and postoperatively obtained risk factors for SAGL were analyzed in univariate and multivariate logistic regression analysis. Twelve (8.8%) of the transplant recipients had SAGL. In multivariate logistic regression analyses using preoperatively assessed variables, the preoperative Model for End-Stage Liver Disease (MELD) score (P < 0.001) and actual GW/recipient standard liver volume (SLV) ratio (P = 0.008) were independent predictors of SAGL. The recommended graft volume by preoperative computed tomography volumetry was calculated as SLV × (1.616 × MELD + 0.344)/100/0.85 (mL) [MELD ≥ 18.2], or SLV × 0.35 (mL) [MELD < 18.2]. The required allograft volume in LDLT can be determined by the preoperative MELD score of the recipient, and patients with higher MELD scores require larger grafts or deceased donor whole liver transplant to avoid SAGL.

Abstract
OBJECTIVE The aim of this work was to evaluate the clinical outcomes of donor hepatic artery to recipient replaced right hepatic artery anastomosis in living-donor liver transplantation. METHODS A retrospective analysis of 12 patients with donor hepatic artery to recipient replaced right hepatic artery anastomosis in living-donor liver transplantation from January 2012 to July 2014 was performed. Age, sex, clinical diagnosis of the liver disease, ABO mismatch, hepatic artery thrombosis, biliary strictures and leakage, graft loss, and mortality rates were evaluated. RESULTS Female-to-male ratio was 4:8. Right lobe was transplanted in 11 (91.7%) of the patients. In 1 patient, left lobe was transplanted. In 9 patients, single duct-to-duct biliary anastomosis was performed with cystic duct catheterization. In 2 patients, double duct-to-duct biliary anastomosis was performed. In 1 patient, double biliary duct-to-duct anastomosis was performed after ductoplasty to achieve a single ductal orifice. No hepatic artery thrombosis was observed. Biliary complications were observed in 6 patients (50%: biliary leaks in 2 patients, biliary stricture in 3 patients, and both in 1 patient). ABO mismatch was not observed. No graft loss due to hepatic artery thrombosis was observed. Mortality was observed in 2 patients (16.6%). CONCLUSIONS Donor hepatic artery to recipient replaced right hepatic artery anastomosis in living-donor liver transplantation is somewhat related to biliary complications, but not associated with increased rates of hepatic artery thrombosis.

Abstract
AIM: To explore a prophylactic procedure to prevent splenic artery steal syndrome (SASS), as well as a therapeutic intervention to correct it.
METHODS: Forty-three liver transplant patients were enrolled in a non-randomized controlled trial, with the eligible criterion that the diameter of the splenic artery is more than 5 mm and/or 1.5 times of the diameter of the hepatic artery. The procedure of splenic artery banding was performed in 28 of the 43 patients, with the other 15 patients studied as a control group. SASS and other complications were compared between these two groups. A new therapeutic intervention, temporary incomplete blockade of the splenic artery with a balloon, was performed to treat SASS in this study.
RESULTS: The incidence of SASS was decreased by banding the splenic artery (0/28 vs 5/15, P = 0.006), and the same result was observed in total complications associated with prophylactic procedures (2/28 vs 6/15, P = 0.014). Five patients in the control group developed SASS within 5 d after OLT, 2 of whom were treated by coil embolization of the splenic artery, whereas the other 3 by temporary blockade of the splenic artery. Reappeared or better hepatic arteries with improved systolic amplitude and increased diastolic flow were detected by Doppler ultrasonography in all the 5 patients. Local splenic ischemic necrosis and nonanastomotic biliary stricture were diagnosed respectively in one patient treated by coil embolization, and no collateral complication was detected in patients treated by temporary blockade of the splenic artery.
CONCLUSION: SASS should be avoided during the operation by banding the splenic artery. Temporary blockade of the splenic artery is a new safe and effective intervention for SASS.

Abstract
AIM: To investigate the diagnostic performance of multi-detector computed tomography (MDCT) in detecting biliary complications after orthotopic liver transplantation (OLT).
METHODS: Eighty-three consecutive OLT recipients, who presented with clinical or biochemical signs of biliary complications, underwent MDCT examination. Two experienced radiologists assessed MDCT images in consensus to determine biliary complications. Final confirmation was based on percutaneous transhepatic cholangiography or endoscopic retrograde cholangiography in 58 patients, surgery in four patients, liver biopsy in 10, and clinical and sonography follow-up in 11 patients.
RESULTS: Biliary complications were eventually confirmed in 62 of 83 patients (74.7%), including anastomotic biliary strictures in 32, nonanastomotic biliary strictures in 21, biliary stones in nine (5 with biliary strictures), anastomotic bile leak in five, and biloma in six (all with nonanastomotic strictures, and 2 with biligenic hepatic abscess). Twenty-one patients had no detection of biliary complications. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MDCT for detecting biliary strictures were 90.6%, 86.7%, 89.2%, 92.3% and 83.9%, respectively. For detecting biliary stones, anastomotic bile leak and biloma, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MDCT were all 100%.
CONCLUSION: MDCT is a useful screening tool for detecting biliary complications after OLT.

Abstract
Vascular complications after liver transplantation increase post-operative morbidity and contribute to the incidence of retransplantation. Vascular complications comprise arterial, caval, and portal venous pathology, with the majority of complications being arterial in etiology, including anastomotic stricture, pseudoaneurysm, and thrombosis. There are two major therapeutic options for the treatment of these arterial complications: endovascular intervention and surgery. The former includes intra-arterial thrombolysis, embolization, percutaneous transluminal angioplasty, and stent placement. The latter includes thrombectomy, reanastomosis, and retransplantation. Although surgical treatment has been considered the first choice for management in the past, advances in endovascular intervention have increased and make it a viable therapeutic option following orthotopic liver transplantation. This review focuses on the role of surgical and endovascular therapy in the management of hepatic arterial complications after liver transplantation.

Abstract
Since 1963, when the first human liver transplantation (LT) was performed by Thomas Starzl, the world has witnessed 50 years of development in surgical techniques, immunosuppression, organ allocation, donor selection, and the indications and contraindications for LT. This has led to the mainstream, well-established procedure that has saved innumerable lives worldwide. Today, there are hundreds of liver transplant centres in over 80 countries. This review aims to describe the main aspects of LT regarding the progressive changes that have occurred over the years. We herein review historical aspects since the first experimental studies and the first attempts at human transplantation. We also provide an overview of immunosuppressive agents and their potential side effects, the evolution of the indications and contraindications of LT, the evolution of survival according to different time periods, and the evolution of methods of organ allocation.
