Abstract
OBJECTIVES Vascular complications after liver transplant can be lethal. High levels of suspicion and aggressive use of diagnostic tools may help with early diagnosis and treatment. Here, we share our experiences regarding this topic. MATERIALS AND METHODS Adult and pediatric patients who had liver transplant between February 1997 and June 2018 in our clinic were included in the study. Patients were grouped according to age (pediatric patients were those under 18 years old), male versus female, indication for transplant, type of liver transplant, type of vascular complication, treatment, and survival aftertreatment.We analyzed the statistical incidence of vascular complications according to age, male versus female, and type of liver transplant. RESULTS Our analyses included 607 liver transplant procedures, including 7 retransplants, with 349 (57.4%) from living donors and 258 (42.6%) from deceased donors. Of total patients, 539 were adults (89.8%) and 61 were children (10.2%). Vascular complications occurred in 25 patients (4.1%), with hepatic artery complications seen in 13 patients (2.1%) (10 adults [1.8%] and 3 children [4.9%]), portal vein complications seen in 9 patients (1.5%) (6 adults [1.1%] and 3 children [4.9%]), and hepatic vein complications seen in 3 patients (0.5%) (2 adults [0.36%] and 1 child [1.6%]). Rate of vascular complications was statistically higher in pediatric patients (11.4% vs 3.3%; P = .007) and higher but not statistically in recipients of livers from living donors (5.2% vs 2.7%; P = .19). Twelve patients (48.8%) were treated with endovascular approach, and 11 (0.44%)required surgicaltreatment. Two patients underwent immediate retransplant due to hepatic artery thrombosis. CONCLUSIONS Because vascular complications are the most severe complications afterlivertransplant,there must be close follow-up of vascular anastomoses, particularly early postoperatively, with radiologic methods. In cases of vascular complications, emergent treatment, including endovascular interventions, surgery, and retransplant, must be performed.

Abstract
OBJECTIVES The blood supply of the liver occurs through the hepatic artery and portal vein. Outflow of blood circulation in the liver is via the hepatic veins. Any disruption in this blood circulation results in deterioration of liver functions. In this study, we evaluated early vascular complications in pediatric liver transplant recipients seen at our center. MATERIALS AND METHODS From November 1988 to December 2021, our team has performed 701 liver transplant procedures, which have included 334 pediatric liver transplants. Among these pediatric liver transplant recipients (mean age of 7.34 y), 176 were male patients. Nineteen patients (5.7%) were recipients of deceased donors. Reason for liver failure was mainly biliary atresia (n = 169). Mean weight of recipients was 23.3 kg. Most graft types were left lateral grafts (n = 204). RESULTS Three patients had hepatic vein complications. All 3 patients were successfully treated with interventional radiological methods by placing a stent in the anastomosis region. Portal vein complications occurred in 3 patients. One patient had hemostasis performed surgically. The second patient had surgically revision of the anastomosis because of thrombus formation. Because of stenosis of more than 50% in the portal vein anastomosis, the third patient required stent placement in the anastomosis region. Hepatic artery complications occurred in 54 patients: 31 patients had hepatic artery thrombosis, 13 patients had hepatic artery stenosis, 7 patients had bleeding from hepatic artery anastomosis, 2 patients had hepatic artery dissection, and 1 patient had pseudoaneurysm in the hepatic artery. Forty-three of these patients were successfully treated with interventional radiological methods and 11 required surgical treatment. CONCLUSIONS Vascular complications after liver transplant can cause deterioration in hepatic functions and acute liver failure. Vascular complications can be successfully treated in experienced organ transplant centers.

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
RATIONALE Despite vast improvements in technique, several complications still challenge surgeons and medical practitioners alike, including biliary and vascular complications, acute and chronic rejection, and disease recurrence. PATIENT CONCERNS A 59-year-old man was admitted to hospital on July, 2016. He had hepatitis B cirrhosis related recurrent hepatocellular carcinoma and underwent living donor liver transplantation in our hospital. DIAGNOSIS At the time of admission, the patient's spirit, diet, sleep, normal urine and stool, and weight did not change significantly. The test indicators are as follows: total bilirubin: 100.1 μmol/L, direct bilirubin: 65.0 μmol/L. Emergency CT in the hospital after admission showed that hepatic artery pseudoaneurysm formation after liver transplantation was observed. INTERVENTIONS This patient underwent minimal invasive endovascular treatment. The demographic, clinical, and laboratory data were collected and reviewed. He was treated successfully by endovascular stent grafting and thrombolytic treatment. OUTCOMES The blood concentration of tacrolimus (FK506) was 6.3 ng/mL total bilirubin 19.6 μmol/L before discharge. The changing of total bilirubin and direct bilirubin were investigated (Fig. 1). The patient recovered well and was discharged 2 weeks later. The patient is doing well and regularly followed up. LESSONS Coil embolization of aneurysmal sac or placement of a stent graft is a minimally invasive alternative to surgery and definitively excludes a bleeding hepatic artery pseudoaneurysm. This technique can be considered as an effective treatment option for hepatic artery pseudoaneurysm instead of a difficult surgical repair.

Abstract
BACKGROUND Hepatic artery pseudoaneurysm (PA) after liver transplantation (LT) is a rare but potentially fatal complication. Among a series of 50 patients of LT, we experienced 3 such cases. Some authors also have reported cases of PA, either intrahepatic or extrahepatic. The aim of this study was to investigate the important factors that affect the treatment outcome. METHODS Three patients were presented. To analyze the factors, not only our patients but also the patients with PA reported in the literature (including 10 case series and 23 case reports) were enrolled for analysis. The possible factors probably affecting the survival were compared statistically, including age, sex, clinical manifestation as bleeding (including gastrointestinal bleeding, hemobilia, or intra-abdominal bleeding), treatment (with embolization or surgical exploration or stent), diagnosis establishment before or after bleeding, and so forth. RESULTS From univariate analysis, the significant factors that affect survival are sex (female) (P = .036), stent treatment (P = .006), and early detection (P = .036), whereas age (P = .493) and presentation with hemorrhage (P = .877) are not significant factors. However, according to multivariate analysis, stent treatment has a borderline significance (P = .056). CONCLUSIONS Early detection of such a life-threatening complication is a key determinant of survival. "Early" does not refer to early postoperative days but means the detection prior to the rupture of the pseudoaneurysm. Postoperative imaging studies such as computed tomographic scan or magnetic resonance cholangiopancreatography early and periodically to follow up the graft status is recommended, especially for those who had received other interventions before or after the liver transplantation.

Abstract
Background Hepatic artery pseudoaneurysm (HAP) and Hepatic artery dissection are rare vascular complications after living donor liver transplantation (LDLT), which may lead to graft loss and death of the recipients. Conventional gray-scale and Doppler ultrasound, as well as contrast-enhanced ultrasound (CEUS), play important roles in identifying vascular complications in the early postoperative period and during follow-up. We report a case of hepatic artery dissection secondary to HAP after LDLT, which was diagnosed and followed for one year by ultrasound. To the best of our knowledge, few studies have reported similar cases after liver transplantation in the English literature. Case presentation A 43-year-old man underwent right-lobe LDLT for treatment of a severe acute hepatitis B infection and was followed up with ultrasound examinations for one year. Conventional gray-scale and Doppler ultrasound combined with contrast-enhanced ultrasound (CEUS) accurately revealed the occurrence of HA dissection secondary to HAP and accompanied by thrombosis and collateral circulation, as well as secondary biliary complications, which provided a prompt diagnosis and guidance for the treatment. Conclusion Our case suggests that ultrasound can help detect hepatic artery pseudoaneurysm and dissection, as well as secondary biliary lesions after LDLT in an accurate and timely manner and provide useful information for the treatment chosen. CEUS shows potential as an important complementary technique to gray-scale and Doppler ultrasound.

Abstract
Living donor liver transplantation (LDLT) has been widely used to treat end-stage liver disease with improvement in surgical technology and the application of new immunosuppressants. Vascular complications after liver transplantation remain a major threat to the survival of recipients. LDLT recipients are more likely to develop vascular complications because of their complex vascular reconstruction and the slender vessels. Early diagnosis and treatment are critical for the survival of graft and recipients. As a non-invasive, cost-effective and non-radioactive method with bedside availability, conventional gray-scale and Doppler ultrasonography play important roles in identifying vascular complications in the early postoperative period and during the follow-up. Recently, with the detailed vascular tracing and perfusion visualization, contrast-enhanced ultrasound (CEUS) has significantly improved the diagnosis of postoperative vascular complications. This review focuses on the role of conventional gray-scale ultrasound, Doppler ultrasound and CEUS for early diagnosis of vascular complications after adult LDLT.

Abstract
Although vascular complications (VCs) following orthotopic liver transplantation (OLT) seldom occur, they are the most feared complications with a high incidence of both graft loss and mortality, as they compromise the blood flow of the transplant (either inflow or outflow). Diagnosis and therapeutic management of VCs constitute a major challenge in terms of increasing the success rate of liver transplantation. While surgical treatment used to be considered the first choice for management, advances in endovascular intervention have increased to make this a viable therapeutic option. Considering VC as a rare but a major and dreadful issue in OLT history, and in view of the continuing and rapid progress in recent years, an update on these uncommon conditions seemed necessary. In this sense, this review comprehensively discusses the important features (epidemiological, clinical, paraclinical, prognostic and therapeutic) of VCs following OLT.

Abstract
OBJECTIVE The purpose of our study was to evaluate the technical feasibility, procedural complications, clinical follow-up, and computed tomography (CT) scan outcomes of hepatic artery pseudoaneurysms (HAPs) treated with stent graft. METHODS Between October 2004 and October 2009, we treated 8 patients with HAPs with stent graft. RESULTS Stent graft deployment was technically successful in all the patients. Complete exclusion of the pseudoaneurysm preserving patency of the hepatic artery was achieved in 6 patients. Total occlusion of the common hepatic artery was observed in 1 patient, and vasospasm of proper hepatic artery and endoleak from distal stent margin were observed in another patient. The 2 patient were controlled through occlusion parent artery with coils. After these procedures, symptoms of bleeding and abdominal pain disappeared. Follow-up enhanced CT scan was performed at an average of 14 months (range, 6-26 months), which showed complete disappearance of the HAP and patency of the stent without intrastent stenosis in 6 patients who had successful deployment of the stent. CONCLUSIONS Endovascular treatment of HAPs using stent graft can maintain the hepatic artery blood flow and could be considered as an alternative to embolization.

Abstract
BACKGROUND Results of preoperative conventional coagulation assays are a poor predictor of hemorrhage after liver transplantation. In this study, we evaluated the factors that are predictive of intra-abdominal coagulopathic hemorrhage after living donor liver transplantation surgery. METHODS During the period from January 2009 to December 2012, 118 adults underwent living donor liver transplantation (LDLT) in our institution. Of those patients, 18 (15.3%) developed intra-abdominal coagulopathic hemorrhage (n = 7) or hemorrhage due to non-coagulopathic causes (n = 11) that required emergency medical, radiological, or surgical intervention within the first month after LDLT. Possible predictors of postoperative coagulopathic hemorrhage included donor-related factors, age, body mass index, MELD score, INR value, intra-operative blood transfusion, graft/recipient weight ratio, anhepatic phase, cold ischemia time, operative time, APACHE II score, onset of re-bleeding, and hemoglobin levels during rebleeding episodes. RESULTS There were no differences in any of the variables between the two groups (coagulopathic and noncoagulopathic hemorrhage) except for cold ischemia time. We found that cold ischemia time was significantly longer in patients with postoperative coagulopathic hemorrhage (160.50 ± 45.02 min) than in patients with hemorrhage due to non-coagulopathic causes (113.55 ± 29.31 min; P = 0.027). CONCLUSION Prolonged cold ischemia time is associated with postoperative intra-abdominal coagulopathic hemorrhage in patients after LDLT. It is, therefore, necessary to shorten the cold ischemia time in order to reduce the risk of postoperative intra-abdominal hemorrhage due to coagulopathic causes.

Abstract
BACKGROUND Interventional radiology has recently been reported as an effective means of treating complications after liver transplantation. In children, however, the number of such reports is relatively small. In addition, there is ongoing discussion regarding the best interventional devices and methods for specific complications. OBJECTIVE The aim of this study was to determine the value of interventional treatment for vessel and bile duct complications after pediatric living-donor liver transplantation. MATERIALS AND METHODS Six cases with lumen-reconstruction-related complications after liver transplantation received intervention. Three cases had hepatic artery thrombosis, one had portal vein stenosis, and two had bilioenteric anastomotic stenosis. Catheter-directed thrombolysis was used to treat cases with hepatic artery thrombosis; balloon dilation and stent placement were used for portal vein stenosis; balloon dilation and drainage were used for bilioenteric anastomotic stenosis. RESULTS All interventions were performed successfully, and treatment efficacy was 100 %. Except for one death from multiple organ failure, all other cases survived through follow-up, which lasted up to 18 months. No case had intervention-related complication. CONCLUSION Interventional treatment is safe and effective, and can be the first choice for the treatment of complications associated with pediatric living-donor liver transplantation.

Abstract
BACKGROUND Hepatic artery stenosis (HAS) is a serious complication of liver transplantation but data on the most effective endovascular management are lacking. We aimed to compare percutaneous balloon angioplasty (PBA) with stent placement. METHODS We searched MEDLINE, Cochrane, Web of Science, EMBASE, SCOPUS, and Biosis Previews between 1970 and December 2011 and performed meta-analysis of short-term (procedural success, complications) and long-term outcomes (liver function, arterial patency, survival, re-intervention, re-transplantation). Random effects models were used for the analysis and meta-regression performed for the year of study. RESULTS A total of 263 liver transplants in 257 patients [age 43 (±8) years] underwent 147 PBAs and 116 stents. Transplanted livers were from deceased donors in 240 (91 %). Follow-up was 1 month to 4.5 years (median 17 months). PBA and stent had similar procedural success (89 % vs. 98 %), complications (16 % vs. 19 %), normal liver function tests (80 % vs. 68 %), arterial patency (76 % vs. 68 %), survival (80 % vs. 82 %), and requirement for re-intervention (22 % vs. 25 %) or re-transplantation (20 % vs. 24 %) (P non-significant). In the most recent studies re-transplantation was reported less compared to older series (P = 0.04). CONCLUSION Both PBA and stent offer comparable results for HAS. These techniques have contributed to a recent decline in re-transplantation. KEY POINTS • Interventional radiological procedures are often used to treat post-transplant hepatic artery stenosis. • Meta-analysis shows that percutaneous balloon angioplasty and stent placement are both efficacious. • Percutaneous balloon angioplasty and stent placement appear to have similar complication rates. • Re-transplantation rates have declined, partly due to interventional management for arterial stenosis.

Abstract
BACKGROUND The aim of the present study was to improve the techniques of hepatic artery (HA) reconstruction and to properly manage arterial complications after living donor liver transplantation (LDLT). METHODS Prospectively collected data collected from 371 patients who underwent adult LDLT using a right lobe from January 2000 to August 2009 were retrospectively reviewed. RESULTS Of 17 patients (4.6%, 17/371) with double HA stumps in the graft, 12 patients (70.6%) received dual HA reconstruction. HA complications were composed of thrombosis (n = 6), pseudoaneurysm (n = 2), and stenosis (n = 4), showing 3.2% (12/371) of incidence. In patients with HA thrombosis, whereas operative thrombectomies with re-anastomosis rescued all the grafts in early attack (n = 3, ≤1 wk), angiographic thrombolysis successfully reestablished the flow in patients with late attack (n = 3, >1 wk). In all patients with HA complications, except for one, all of our treatment modalities - operation and angiographic intervention - resulted in successful rescue of grafts and no patient received re-transplantation because of HA complications. CONCLUSION Prompt diagnosis of HA complications by serial post-operative Doppler ultrasound and corresponding treatment strategies, including operative and radiological intervention, can rescue both grafts and patients without necessitating re-transplantation.

Abstract
Improving outcomes in very small children is a major goal of pediatric liver transplantation. This report describes our experience of living related liver transplantation in an infant weighing 3.98 kg. The recipient, a 80-day-old male infant with congenital biliary atresia, was treated with living donor liver transplantation and then followed up for 6 months. The left lateral segment (segment II, III) with reduced size from the donor, his 26-year-old mother, was used as the graft. The graft weighed 200 g. The graft weight to recipient body weight ratio was 5.025%. The donor regained her liver function within 3 days and was discharged on day 8. The patient showed good results. Liver function returned to normal 9 days after the operation with bilirubin level almost decreased to normal. Cyclosporin, mycophenolate mofetil and prednisone were used for postoperative immunosuppression. No bleeding, thrombosis, infection or bile leakage occurred. The patient had slight fever because of a little collection in the abdomen and recovered after paracentesis and drainage. He was discharged on day 16. The donor and recipient are in satisfactory condition at present. Improvement of technique in hepatic surgery, microsurgical technique in vascular surgery and postoperative intensive care are the keys to ensure the success of the procedure.
