Abstract
Hepatic artery thrombosis (HAT) is a common cause of graft loss in living-donor liver transplantation, occurring in ~2.5%-8% of patients. Some right lobe grafts have 2 hepatic arteries (HAs), and the optimal reconstruction technique remains controversial. This study aimed to identify risk factors for HAT and to evaluate the efficacy of reconstructing 2 HAs in right lobe grafts. This retrospective, single-center study analyzed 1601 living-donor liver transplantation recipients with a right liver graft and divided them into 1 HA (n = 1524) and 2 HA (n = 77) groups. The reconstruction of all HAs was performed using a microscope with an interrupted suture. The primary outcome was any HAT event. Of the 1601 patients, 37.8% had a history of transcatheter arterial chemoembolization, and 130 underwent pretransplant hepatectomy. Extra-anatomical arterial reconstruction was performed in 38 cases (2.4%). HAT occurred in 1.2% of patients (20/1601) who underwent surgical revascularization. In the multivariate analysis, undergoing pretransplant hepatectomy ( p = 0.008), having a female donor ( p = 0.02), having a smaller graft-to-recipient weight ratio ( p = 0.002), and undergoing extra-anatomical reconstruction ( p = 0.001) were identified as risk factors for HAT. However, having 2 HA openings in right liver grafts was not a risk factor for HAT in our series. Kaplan-Meier survival analysis showed no significant difference in graft survival and patient survival rates between the 1 HA and 2 HA groups ( p = 0.09, p = 0.97). In our series, although the smaller HA in the 2 HA group should increase the risk of HAT, HAT did not occur in this group. Therefore, reconstructing both HAs when possible may be a reasonable approach in living-donor liver transplantation using a right liver graft with 2 HA openings.

Early hepatic artery thrombosis treatments and outcomes: aorto-hepatic arterial conduit interposition or revision of anastomosis? BMC Surg 2024; 24:62. [PMID: 38368356 PMCID: PMC10874575 DOI: 10.1186/s12893-024-02359-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 02/14/2024] [Indexed: 02/19/2024] Open
Abstract
BACKGROUND Hepatic artery thrombosis (HAT) is one of the critical conditions after an orthotopic liver transplant (OLT) and leads to severe problems if not corrected promptly. However, multiple treatments have been proposed for HAT, in which surgical revascularization with either auto-hepatic conduit interposition (AHCI) or revision of the anastomosis is more familiar indeed indicated for some patients and in specific situations. In this study, we want to evaluate the success and outcomes of treating early HAT (E-HAT), which defines HAT within 30 days after OLT with either of the surgical revascularization techniques. METHOD In this retrospective study, we collected information from the medical records of patients who underwent either of the surgical revascularization procedures for E-HAT after OLT. Patients who needed early retransplantation (RT) or died without surgical intervention for E-HAT were excluded. Demographic data, OLT surgery information, and data regarding E-HAT were gathered. The study outcomes were secondary management for E-HAT in case of improper inflow, biliary complications (BC), RT, and death. RESULTS A total of 37 adult patients with E-HAT after OLT included in this study. These E-HATs were diagnosed within a mean of 4.6 ± 3.6 days after OLT. Two patients had their HA revised for the initial management of E-HAT; however, it changed to AHCI intraoperatively and finally needed RT. Two and nine patients from the AHCI and revision groups had re-thrombosis (12.5% vs. 47.3%, respectively, p = 0.03). RT was used to manage rethrombosis in all patients of AHCI and two patients of the revision group (22.2%). In comparison to the AHCI, revision group had statistically insignificant higher rates of BC (47.4% vs. 31.2%); however, RT for nonvascular etiologies (12.5% vs. 5.3%) and death (12.5% vs. 10.5%) were nonsignificantly higher in AHCI group. All patients with more than one HA exploration who were in the revision group had BC; however, 28.5% of patients with just one HA exploration experienced BC (p < 0.001). CONCLUSION Arterial conduit interposition seems a better approach for the initial management of E-HAT in comparison to revision of the HA anastomosis due to the lower risk of re-thrombosis and the number of HA explorations; indeed, BC, RT, and death remain because they are somewhat related to the ischemic event of E-HAT than to a surgical treatment itself.

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.

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
BackgroundThe incidence of hepatic artery thrombosis in pediatric living donor liver transplantation (LDLT) is significantly higher than that in adults, and is closely related to the surgeon’s experience with hepatic artery anastomosis. However, there are few studies on the learning curve of hepatic artery anastomosis among surgeons.MethodsWe collected data related to 75 patients who underwent pediatric LDLT and hepatic artery anastomosis independently by the same surgeon. Cumulative sum method (CUSUM) was used to analyse the duration of hepatic artery anastomosis and determine the cut-off value. Patients were divided into two phases according to CUSUM. We analysed the intraoperative and postoperative data and survival outcomes of the included patients.ResultsTotal anastomosis duration decreased with an increased number of completed procedures, and the average duration was 42.4 ± 2.20 min. A cut-off value and two phases were identified: 1–43 cases and 44–75 cases. Intraoperative blood loss was significantly lower in phase 2 than in phase 1. The immediate functional changes of total bilirubin (TBIL) and direct bilirubin (DBIL) were significantly also lower in phase 2 than in phase 1. Other functional outcomes, postoperative complications, and the long-term survival rate were not significantly different between the two phases.ConclusionsTechnical competence in pediatric LDLT hepatic artery anastomosis may be achieved after completing 43 cases. It is a safe procedure with a surgical loupe that can be systematized and adopted by pediatric surgeons with sufficient experience via a relatively long learning curve.

Abstract
Hepatic artery thrombosis (HAT) following living donor liver transplantation (LDLT) is a lethal complication. We present the case of a patient who underwent salvage redo hepatic artery reconstruction using an aorto-hepatic jump graft because of HAT following LDLT. A 64-year-old female patient diagnosed with hepatitis C virus-associated liver cirrhosis and hepatocellular carcinoma underwent salvage LDLT using a modified right liver graft. Partial graft infarct was identified at posttransplant day 4, and by day 9, it had spread. Celiac arteriography showed complete occlusion of the graft hepatic artery. We performed redo hepatic artery reconstruction using a fresh iliofemoral artery homograft 10 days after the LDLT operation because such a vessel homograft was available at our institutional tissue bank. The infrarenal aorta was dissected and an iliofemoral artery graft was anastomosed. Soon after hepatic artery revascularization, liver function progressively improved, and the infarct area at the liver graft was reduced. The patient has been doing well for 10 years without any vascular complications. In conclusion, our experience with this case suggests that salvage redo hepatic artery reconstruction using an aorto-hepatic jump graft is a feasible option to treat HAT following LDLT, as in deceased donor liver transplantation.

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
Aberrant donor hepatic artery anatomy or hepatic artery injury during organ procurement or recipient preparation poses a surgical challenge during deceased donor liver transplantation. In this study, we aimed to investigate arterial reconstruction using microvascular techniques during deceased donor liver transplantation and suggest reasonable indications for the microsurgical approach in this setting. We retrospectively reviewed the outcomes of 470 deceased donor liver transplantations performed at our institution between July 2011 and December 2015. Of these, 128 recipients underwent microsurgical hepatic artery reconstruction and 342 underwent reconstruction with surgical loupes. Thirty-two patients (6.8%) experienced hepatic artery-related complications, including hepatic artery thrombosis (n = 8, 1.7%). In the propensity score-matched cohort, the surgical loupe group showed a higher complication rate (P = .782). On multivariate analysis, cold ischemia time (odds ratio, 0.995; 95% confidence interval, 0.9920-0.999; P = .009) and use of aortohepatic conduits (odds ratio, 5.254; 95% confidence interval, 1.878-14.699; P = .002) were independent predictors of arterial complications. The low incidence of hepatic artery complications in this study is likely attributable to the active application of microsurgical techniques. Active application of back-table microsurgical plasty and selective application of microsurgical techniques for main arterial reconstruction may help minimize operative difficulties and arterial complications.

Abstract
Intrahepatic recipient hepatic artery dissection caused by hepatic artery thrombosis is a lethal complication of living-liver donor liver transplantation (LDLT). We herein report a new surgical technique that avoids the ligation of the recipient hepatic arteries in LDLT. Patients undergoing LDLT between 2009 and 2019 were evaluated. In the second half of this period, a technique involving no ligation of the recipient hepatic artery was initiated and its impact on the incidence of intrahepatic recipient hepatic artery dissection was determined. The middle and left hepatic arteries were ligated in 195 cases (53.4%), and the no-ligation technique was used in 170 (46.6%). The incidence of intraoperative hepatic artery dissection was significantly lower in the no-ligation group (n = 0, 0.0%) than in the ligation group (n = 10, 5.1%) (p = 0.0021). After propensity score matching to evaluate the patient characteristics, the incidence of intraoperative hepatic artery dissection was also significantly lower in the no-ligation group (n = 0, 0.0%) than in the ligation group (n = 6, 4.5%) (p = 0.0295). As a result, this new surgical technique is highly recommended to avoid recipient hepatic artery ligation in LDLT.

Abstract
Hepatic artery thrombosis (HAT) following pediatric liver transplantation increases morbidity and risk of graft failure. We performed a retrospective chart review of all patients who underwent deceased-donor liver transplantation from August 2002 to July 2016. Multi-organ transplant recipients were excluded. We examined the incidence of HAT at our institution and sought to identify associated donor or recipient risk factors. A total of 127 deceased-donor liver transplant patients with a median age of 1.7 years (IQR 0.67-6.7) were identified. Of those, 14 developed HAT, all weighing under 25 kg. Among 100 patients under 25 kg, whole-liver graft recipients had an odds ratio of 3.98 (95% confidence interval [CI]: 1.03, 15.34; P = .045) for developing HAT compared with split-liver graft recipients. Within the whole-liver recipient group under 25 kg, 11 patients developed HAT with a median donor-to-recipient ratio (DRWR) of 0.9 (IQR: 0.7-1.2) compared with a median DRWR of 1.4 (IQR: 1.1-1.9) for those who did not develop HAT. Multivariate analysis showed DRWR to be an independent risk factor for HAT in patients weighing under 25 kg who received whole organ grafts, with an odds ratio of 3.89 (95% CI: 1.43, 10.54; P = .008) for each 0.5 unit decrease in DRWR. Our results suggest that in recipients under 25 kg 1) split-liver grafts may have a lower rate of HAT and 2) selecting whole organ donors with a higher DRWR may decrease the incidence of HAT.

Abstract
Background Hepatic artery (HA) reconstruction in living donor liver transplantation (LDLT) is more technically demanding than deceased donor LT (DDLT) because of the small diameter and short HA stump of the partial liver graft. Hence, hepatic artery thrombosis (HAT) can occur infrequently even though the HA is reconstructed microscopically. HAT is closely related to graft failure and mortality. Therefore, HAT should be detected early and HA flow reconstituted using several arterial inflows. We successfully performed redo HA reconstruction in LDLT and report our management process and outcomes. Material/Methods The right gastroepiploic artery (RGEA) was used in 15 patients, previous native HA in 3, and interposition graft from the aorta in 1. All HA reconstructions were performed under a microscope using the end-to-end interrupted suture method. We reviewed technical feasibility, cause of hepatic artery revision (HAR), patency of redo HA flow, graft salvage rate, time of revision, biliary complications, and mortality. Results Ten of 21 cases were salvage LT. Biliary complications developed in 6 cases. The mean interval of HAR with the RGEA was 1.5±1.2 postoperative days. All patients were alive without lethal complications of HAT during the mean follow-up period of 23.3 months. In the other 6 cases of HAR without using the RGEA, we performed redo HA reconstruction after thrombectomy with the native right HA (n=2), right gastric artery, left HA, gastroduodenal artery, and jump graft from the aorta (n=1, respectively). Among them, 3 died from biliary sepsis, graft dysfunction from large-sized ischemic injury, and pneumonia. Conclusions HAR with the RGEA is feasible for HAT management in LDLT patients without adequate hepatic arteries. When all inflows mentioned are unavailable, jump graft from the aorta using a cadaveric fresh iliac artery may be feasible.

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
A right liver graft with multiple hepatic artery (HA) stumps can be found in approximately 5% of living donor liver transplantation (LDLT) using a right lobe graft. From January 2000 to June 2014, 1149 patients underwent LDLT procedures. Thirty patients with LDLT using a right lobe graft with multiple HA stumps and 149 patients with LDLT using a right lobe graft with a single HA stump were enrolled. These patients were divided into 3 groups: single HA (group 1, n = 149), multiple HAs with total reconstruction (group 2, n = 19), and multiple HAs with selective partial reconstruction (group 3, n = 11). Selective partial reconstruction was performed only when pulsatile back-bleeding was confirmed after larger HA reconstruction and sufficient intrahepatic arterial flow was confirmed by Doppler ultrasound (DUS). In group 2, the donor HAs were smaller (P < .001), and HA reconstruction took longer (P < .001). However, there was no significant difference among the groups regarding the arterial complication rate, biliary complication rate, and patient and graft survival. In conclusion, selective partial reconstruction of HA stumps for LDLT using a right lobe graft was feasible when intrahepatic arterial communication was confirmed by pulsatile back-bleeding from the smaller artery and DUS.

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
In living donor liver transplantation (LDLT), a left hepatic graft occasionally includes a replaced or accessory left hepatic artery (LHA). The procuring of such grafts requires extensive dissection along the lesser curvature of the stomach to elongate the replaced or accessory LHA on the donor side. On the recipient side, complicated arterial reconstruction is often necessary to use such grafts. We retrospectively reviewed the medical records of 206 adult recipients who underwent LDLT and their respective donors. The recipients and donors were divided into two groups according to the presence of the replaced or accessory LHA. Twenty-five grafts included a replaced or accessory LHA. Only one hepatic artery-related complication was observed in the current series, in which a pseudoaneurysm arose at the site of anastomosis between the donor accessory LHA and the recipient LHA. There was no increase in the incidence of postoperative complications in the donors with a replaced or accessory LHA in comparison with the donors without these arteries. The use of left hepatic grafts that included a replaced LHA or accessory LHA did not have any negative impact on the outcomes on either the donor or the recipient side.

Abstract
Partial liver grafts used in living donor liver transplantation (LDLT) may have multiple hepatic artery (HA) stumps. This study was designed to validate the safety of partial reconstruction of multiple HAs in pediatric LDLT cases. From January 2000 to June 2014, 136 pediatric LDLT recipients were categorized into three groups: single HA group (Group 1, n = 74), multiple HAs with total reconstruction group (Group 2, n = 23), and multiple HAs with partial reconstruction group (Group 3, n = 39). Partial reconstruction was performed only when there was pulsatile back-bleeding after larger HA reconstruction and sufficient intrahepatic arterial flow was confirmed by Doppler ultrasound (DUS). There was no significant difference in biliary complication rate, artery complication rate, patient survival, and graft survival among these groups. Risk factor analysis revealed that the presence of multiple HAs and partial reconstruction of multiple HAs were not risk factors of biliary anastomosis stricture. In conclusion, partial reconstruction of HAs during pediatric LDLT using a left liver graft with multiple HA stumps does not increase the risk of biliary anastomosis stricture or affect graft survival when intrahepatic arterial communication is confirmed by pulsatile back-bleeding and DUS.
