Abstract
Hepatic artery (HA) pseudoaneurysm rupture is a rare and potentially lethal pathology. We present the case of a celiac artery dissection complicated by an HA pseudoaneurysm rupture that was treated successfully with endovascular stenting. The patient's postoperative course was uncomplicated, and he was further evaluated for an underlying connective tissue disorder. There is no standard treatment for a ruptured HA pseudoaneurysm, although transarterial embolization is most frequently reported. This report demonstrates that self-expanding stent grafts are effective in the emergent repair of HA pseudoaneurysm rupture.

Abstract
Coronavirus disease 2019-related transplant hepatic pseudoaneurysms have not been reported but can be life-threatening. They can be either solitary or multiple and can grow rapidly within weeks. They should be classified as mycotic and treated on an emergent basis. Both stenting of the vessel and coil embolization can potentially be viable treatment options of coronavirus disease 2019-related pseudoaneurysms.

Abstract
OBJECTIVE Portal hypertension leads to hepatic artery dilatation and a higher risk of bleeding. We tried to identify the bleeding risk after gastroesophageal varices (GOV) treatment using hepatic artery diameter of contrast-enhanced CT. METHODS Retrospective retrieval of 258 patients with cirrhosis who underwent contrast-enhanced CT from January 2022 to May 2023 and endoscopy within one month thereafter at Hainan Affiliated Hospital of Hainan Medical University. Cirrhotic patients before GOV treatment were used as the test cohort (n = 199), and cirrhotic patients after GOV treatment were used as the validation cohort (n = 59). The grading and bleeding risk was classified according to the endoscopic findings. Arterial-phase images of contrast-enhanced CT were used for coronal reconstruction, and the midpoint diameter of the hepatic artery was measured on coronal images. The optimal cutoff value for identifying bleeding risk was analyzed and calculated in the test cohort, and its diagnostic performance was evaluated in the validation cohort. RESULTS In the test cohort, hepatic artery diameters were significantly higher in high-risk GOV than in low-risk GOV [4.69 (4.31, 5.56) vs. 3.10 (2.59, 3.77), P < 0.001]. With a hepatic artery diameter cutoff value of 4.06 mm, the optimal area under the operating characteristic curve was 0.940 (95% confidence interval: 0.908-0.972), with a sensitivity of 0.887, a specificity of 0.892, a positive predictive value of 0.904, and a negative predictive value of 0.874 for identifying bleeding risk in the test cohort, while in the validation cohort, the sensitivity was 0.885, specificity was 0.939, positive predictive value was 0.920, and negative predictive value was 0.912. CONCLUSION Hepatic artery diameter has high diagnostic performance in identifying bleeding risk after GOV treatment.

Abstract
Emerging evidence indicates the presence of vascular abnormalities and ischemia in biliary atresia (BA), although specific mechanisms remain undefined. This study examined both human and experimental BA. Structural and hemodynamic features of hepatic arteries were investigated by Doppler ultrasound, indocyanine green angiography, microscopic histology, and invasive arterial pressure measurement. Opal multiplex immunohistochemistry, western blot, and RT-PCR were applied to assess Notch3 expression and the phenotype of hepatic arterial smooth muscle cells (HASMCs). We established animal models of Notch3 inhibition, overexpression, and knockout to evaluate the differences in overall survival, hepatic artery morphology, peribiliary hypoxia, and HASMC phenotype. Hypertrophic hepatic arteriopathy was evidenced by an increased wall-to-lumen ratio and clinically manifested as hepatic arterial hypertension, decreased hepatic artery perfusion, and formation of hepatic subcapsular vascular plexuses (HSVPs). We observed a correlation between overactivation of Notch3 and phenotypic disruption of HASMCs with the exacerbation of peribiliary hypoxia. Notch3 signaling mediated the phenotype alteration of HASMCs, resulting in arterial wall thickening and impaired oxygen supply in the portal microenvironment. Inhibition of Notch3/Hey1 ameliorates portal hypoxia by restoring the balance of contractile/synthetic HASMCs, thereby preventing hypertrophic arteriopathy in BA.

Abstract
PURPOSE The presence of an aberrant right hepatic artery (aRHA), arising from the superior mesenteric artery, is a common variant of the liver vascular anatomy. Considering that tumor spread occurs along vessels, the question arises, whether the presence of an aRHA influences the oncologic outcome after resection for cancer of the pancreatic head. METHODS Patients with ductal adenocarcinoma of the pancreatic head, who underwent resection from 2011 to 2020 at the Frankfurt University Hospital, Germany, were analyzed retrospectively. Surgical records and computed tomography imaging were reviewed for the presence of aRHA. Overall and disease-free survival as well as hepatic recurrence were analyzed according to the presence of aRHA. RESULTS aRHA was detected in 21 out of 145 patients (14.5%). The median overall survival was 26 months (95%CI 20.8-34.4), median disease-free survival was 12.1 months (95%CI 8.1-17.3). There was no significant difference in overall survival (26.1 versus 21.4 months, adjusted hazard ratio 1.31, 95%CI 0.7-2.46, p = 0.401) or disease-free survival (14.5 months versus 12 months, adjusted hazard ratio 0.98, 95%CI 0.57-1.71, p = 0.957) without and with aRHA. The hepatic recurrence rate was 24.4.% with conventional anatomy versus 30.8% with aRHA (adjusted odds ratio 1.36, 95%CI 0.3-5.38, p = 0.669). In the multivariable analysis, only lymphatic vessel invasion was an independent prognostic factor for hepatic recurrence. CONCLUSIONS The presence of an aRHA does not seem to influence the long-term survival and hepatic recurrence after resection for ductal adenocarcinoma of the pancreatic head.

Abstract
PURPOSE To evaluate the response to nifedipine administration measured by changes in hepatic arterial (HA) flow on post-operative Doppler ultrasound (US) to predict short-term complications and long-term outcomes in liver transplant (LT) patients. METHODS Patients who underwent LT with post-operative Doppler US within 3 days between 1 January 2005 and 31 December 2015 were included in this retrospective single center study. The patients who received and did not receive nifedipine during the Doppler US comprised the study and control groups, respectively. A positive response to nifedipine was defined as the detection of HA flow when none was present initially or a reduction in HA resistive index (RI) ≥ 0.1 after nifedipine administration. The rates of re-transplantation, re-operation, percutaneous intervention (PCI), and overall survival (OS) were recorded. Cox proportional hazards regression was used to evaluate the association of clinic-demographic variables and Doppler findings with the outcome measures. RESULTS 444 LT patients (305 M/139F, mean age 51.7 ± 17.4 years, mean interval between LT-Doppler US 1.12 ± 0.9 days) are presented. 220 patients comprised the nifedipine study group [n = 157/220 (71.4%) responder, n = 63/220 (28.6%) nonresponder] and 224 patients comprised the control group. There was no difference in re-transplantation or PCI rates between the groups (all p-values ≥ 0.2 and ≥ 0.08, respectively). The responder group had a lower rate of re-operation vs. the control group (15.9% vs. 24.1%, p = 0.03) and nonresponder group (15.9% vs. 31.8%, p = 0.004). 1-year and 2-year OS were similar between the groups (all p-values > 0.37). CONCLUSION Short-term complication rates and long-term outcomes for patients with liver transplant who responded to nifedipine administration on Doppler US are similar to those who did not require nifedipine administration. A lack of response to nifedipine was associated with a higher re-operation rate.

Abstract
BACKGROUND The anastomosis of donor and recipient hepatic arteries is standard in liver transplantations. For transplant recipients with unusable hepatic arteries, appropriate artery selection should be conducted using evidence-based considerations; therefore, this network meta-analysis (NMA) aimed to analyze the most suitable alternative recipient artery for anastomosis during liver transplantations. METHODS Comprehensive searches of the Scopus, Cochrane Library, and MEDLINE databases were conducted to analyze observational studies containing non-standard anastomoses in liver transplantations that used the splenic artery, aorta, celiac, or branches of the gastric artery. The outcome parameters included intraoperative components, complications, and survival data. This NMA used the BUGSnet package in R studio and the results were presented in a Forest plot, league table, and SUCRA plot. RESULTS Among the 13 studies included in this NMA, 5 arteries were used for the anastomoses. The splenic artery anastomosis showed a high risk of thrombosis and a low risk of stenosis (OR 1.12, 95% CI 0.13-3.14) and biliary tract abnormalities (OR 0.79, 95% CI 0.36-1.55). In addition, the graft survival (OR 1.08; 95% CI 0.96-1.23) and overall survival (1-year survival OR 1.09, 95% CI 0.94-1.26; 5-year survival OR 1.95% CI 0.83-1.22) showed favorable results using this artery. Constraints to the use of the splenic artery were longer operation and cold ischemic times. However, the duration of hospital stay (MD 1.36, 95% CI -7.47 to 10.8) was shorter than that when the other arteries were used, and the need for blood transfusions was minimal (MD -1.74, 95% CI -10.2 to 6.7). CONCLUSION In recipients with unusable hepatic arteries, the splenic artery of the patient should be the first consideration for anastomosis selection in liver transplantations.

Abstract
Hepatic artery thrombosis (HAT) is a devastating vascular complication following liver transplantation, requiring prompt diagnosis and rapid revascularization treatment to prevent graft loss. At present, imaging modalities such as ultrasound, computed tomography, and magnetic resonance play crucial roles in diagnosing HAT. Although imaging techniques have improved sensitivity and specificity for HAT diagnosis, they have limitations that hinder the timely diagnosis of this complication. In this sense, the emergence of artificial intelligence (AI) presents a transformative opportunity to address these diagnostic limitations. The develo pment of machine learning algorithms and deep neural networks has demon strated the potential to enhance the precision diagnosis of liver transplant com plications, enabling quicker and more accurate detection of HAT. This article examines the current landscape of imaging diagnostic techniques for HAT and explores the emerging role of AI in addressing future challenges in the diagnosis of HAT after liver transplant.

Abstract
Arterial variations in the liver's blood supply play a pivotal role in the success of pancreatoduodenectomy (PD), impacting both its technical execution and oncological outcomes. Among these variations, a common hepatic artery arising from the superior mesenteric artery (SMA) occurs in about 3% of cases. An exceptionally rare variation is the intrapancreatic common hepatic artery (IPCHA). Preserving or reconstructing the IPCHA is vital during PD to prevent liver and biliary necrosis. Particularly for cases of pancreatic cancer with high rates of intrapancreatic perineural spread, preserving IPCHA without compromising radicality presents challenges. We present a detailed report of the technique used for PD in the presence of IPCHA. Surgical technique details include a pylorus-preserving PD with the Cattell-Braasch maneuver, an artery-first approach, and meticulous dissection using "cold" scissors. We emphasize the importance of strategic surgical planning based on high-quality imaging studies, underscoring the need for pancreatic surgeons to be proficient in managing variations in visceral vessels. In conclusion, this case underscores the significance of navigating rare arterial variations in liver supply during PD, highlighting the necessity for meticulous surgical planning and execution.

Abstract
PURPOSE Anomalies of the right hepatic artery (RHA) may represent an additional challenge in pancreatoduodenectomy (PD). The aim of this study is to assess the potential impact of variations in hepatic arterial anatomy on perioperative outcomes. METHODS PDs performed for periampullary malignancies between 2017 and 2022 were retrospectively enrolled and subdivided in two groups: modal pattern of vascularization (MPV) and anomalous pattern of vascularization (APV). A propensity score matching (PSM) analysis was conducted to homogenize the two study populations. The two groups were then compared in terms of perioperative outcomes and pathological findings. RESULTS Thirty-eight patients (16.3%) out of 232 presented a vascular anomaly: an accessory RHA in 7 cases (3%), a replaced RHA in 26 cases (11.2%), and a replaced HA in 5 cases (2.1%). After PSM, 76 MPV patients were compared to the 38 APV patients. The incidence rate of postoperative complications was comparable between the two study populations (p=0.2). Similarly, no difference was detected in terms of histopathological data, including margin status. No difference was noted in terms of intraoperative hemorrhage and vascular resection. CONCLUSION When PDs are performed in high-volume centers, the presence of an APV of the RHA does not relate to a significant impact on perioperative complications. Moreover, no influence was noted on histopathological findings.

Abstract
BACKGROUND Hepatic artery obstruction is a critical consideration in graft outcomes after living donor liver transplantation. We report a case of diffuse arterial vasospasm that developed immediately after anastomosis and was managed with an intra-arterial infusion of lipo-prostaglandin E1 (PGE1). CASE SUMMARY A 57-year-old male with hepatitis B virus-related liver cirrhosis and hepatocellular carcinoma underwent ABO-incompatible living donor liver transplant. The grafted hepatic artery was first anastomosed to the recipient's right hepatic artery stump. However, the arterial pulse immediately weakened. Although a new anastomosis was performed using the right gastroepiploic artery, the patient's arterial pulse rate remained poor. We attempted angiographic intervention immediately after the operation; it showed diffuse arterial vasospasms like 'beads on a string'. We attempted continuous infusion of lipo-PGE1 overnight via an intra-arterial catheter. The next day, arterial flow improved without any spasms or strictures. The patient had no additional arterial complications or related sequelae at the time of writing, 1-year post-liver transplantation. CONCLUSION Angiographic evaluation is helpful in cases of repetitive arterial obstruction, and intra-arterial infusion of lipo-PGE1 may be effective in treating diffuse arterial spasms.

Abstract
INTRODUCTION The normal anatomy of the celiac trunk (CT) is characterized by splitting into three branches in approximately 80 % of cases. In other cases, multiple anatomical variations can be observed. The purpose of this study was to review the clinical case featuring an extremely rare location of common hepatic artery (CHA) and to emphasize the importance of being familiar with possible anatomical variations of the hepatic artery through preoperative imaging in preparation for oncological surgery. PRESENTATION OF CASE A 71-year-old patient presented with Siewert III cardioesophageal junction cancer with liver metastases (T2N2M1, stage IV). Preoperative contrast-enhanced computed tomography (CECT) showed that the CHA branched from the AA. The operation included the proximal resection of the stomach and abdominal esophagus, D2 lymph nodes dissection, peritumoral liver resection, and extramucosal pyloroplasty. DISCUSSION We report a rare anatomical variation of replaced common hepatic artery, when it is located as VI type of Hiatt's classification - CHA branching from abdominal aorta (AA). It was discovered during contrast-enhanced computed tomography and illustrated by 3D reconstruction of vascular architectonics of the celiac trunk. CONCLUSION This case shows the importance of preoperative preparation using CECT to identify anatomical variations of the CHA, particularly for patients with locally advanced and metastatic cancer.

Abstract
INTRODUCTION Hepatic Artery Pseudoaneurysm (HAP) is a rare and potentially fatal complication following liver transplantation, with unclear etiology. Various predisposing factors, including local infections, biliary-enteric anastomosis, particularly Roux-en-Y hepaticojejunostomy, vascular interventions, and iatrogenic injuries, have been identified. PRESENTATION OF CASE We report a case of HAP occurring after liver re-transplantation in a twenty-year-old male patient who had initially undergone liver transplantation for cirrhosis resulting from autoimmune hepatitis. Subsequently diagnosed with chronic ischemic liver disease accompanied by diffuse cholangiopathy and a liver abscess, the patient underwent a liver re-transplantation. Within the early days post-re-transplantation, the patient presented symptoms of gastrointestinal bleeding and sudden hypotension. A high clinical suspicion led to prompt laparotomy, ultimately successful preserving both the graft and the recipient's life. DISCUSSION HAP is an uncommon complication following liver transplantation. This condition may remain asymptomatic until the rupture of the HAP, which can result in gastrointestinal bleeding, hypotension, and, eventually, mortality. While there have been emerging non-surgical techniques proposed for HAP treatment, surgical intervention remains the definitive solution for preserving the graft and ensuring the recipient's survival. CONCLUSION HAP, while uncommon, represents a life-threatening complication post-transplantation. In the event of rupture, immediate intervention is imperative for the patient's survival. Hence, it is critical for surgeons to be cautious about this complication, recognize its symptoms, and be aware of associated risk factors.

Abstract
BACKGROUND Anatomical variations in the liver arterial supply are quite common and can affect the surgical strategy when performing a minimally invasive pancreaticoduodenectomy (MIPD). Their presence must be preemptively detected to avoid postoperative liver and biliary complications. DATA SOURCES Following the PRISMA guidelines and the Cochrane protocol we conducted a systematic review on the management of an accessory or replaced right hepatic artery (RHA) arising from the superior mesenteric artery when performing an MIPD. RESULTS Five studies involving 118 patients were included. The most common reported management of the aberrant RHA was conservative (97.0%); however, patients undergoing aberrant RHA division without reconstruction did not develop liver or biliary complications. No differences in postoperative morbidity or long-term oncological related overall survival were reported in all the included studies when comparing MIPD in patients with standard anatomy to those with aberrant RHA. CONCLUSIONS MIPD in patients with aberrant RHA is feasible without increase in morbidity and mortality. As preoperative strategy is crucial, we suggested planning an MIPD with an anomalous RHA focusing on preoperative vascular aberrancy assessment and different strategies to reduce the risk of liver ischemia.

Abstract
Although rare, hepatic artery aneurysms are associated with a high morbidity and mortality, necessitating a prompt diagnosis. A significant proportion of hepatic artery aneurysms are pseudoaneurysms, and the major risk factors of which have already been identified in previous literatures. Presentation can be variable, but diagnosis almost relies entirely on computed tomography and digital subtraction angiography. The endovascular approach has progressively become the preferred option due to its better performance when compared to the traditional surgical approach. However, formulation of an endovascular treatment plan for these lesions remains difficult as multiple factors should be considered to identify the best endovascular treatment modality. Five cases of pseudoaneurysm due to recent Whipple operation, hepatobiliary infections, and underlying malignancy are presented in this article to illustrate the effectiveness and complexity of endovascular treatment in this disease entity.

Abstract
The liver has a complex vascular anatomy with a unique dual blood supply. Clinical conditions of the liver vary widely and include disorders originating in the vascular and biliary systems as well as the parenchyma. In most vascular disorders, the effects on the liver are generally subclinical because of its abundant blood supply. However, early diagnosis of such vascular diseases can significantly reduce patient morbidity and mortality. Because imaging findings of vascular disease are not always readily apparent, diagnosis can be difficult. Computed tomography angiography is an excellent imaging modality for visualizing the vascular anatomy of patients for treatment planning. In this review article, we focus on the vascular anatomy of the liver and the imaging findings in some acute hepatic vascular diseases.

Abstract
PURPOSE Vascular resection (VR) is extended surgery to attain a negative radial margin (RM) for distal cholangiocarcinoma (DCC). The present study explored the significance of VR for DCC, focusing on VR, RM, and findings suggestive of vascular invasion on multidetector-row computed tomography (MDCT). METHODS Patients with DCC who underwent resection between 2002 and 2019 were reviewed. RESULTS Among 230 patients, 25 received VR. The overall survival (OS) in the VR group was significantly worse than in the non-VR group (16.7% vs. 50.7% at 5 years, P < 0.001). Patients who underwent VR with a negative RM failed to show a better OS than those who did not undergo VR with a positive RM (19.7% vs. 35.7% at 5 years, P = 0.178). Of the 30 patients who were suspected of having vascular invasion on MDCT, 11 did not receive VR because the vessels were freed from the tumor; these patients had a significantly better OS (57.9% at 5 years) than those who underwent VR. CONCLUSIONS VR for DCC was associated with a poor prognosis, even if a negative RM was obtained. VR is not necessary for DCC when the vessels are detachable from the tumor.

Abstract
PURPOSE To evaluate primary patency at 12 months after endovascular therapies in hepatic artery stenosis. METHODS A retrospective review of all endovascular interventions for hepatic artery stenosis (HAS) after liver transplantation that occurred between June 2013 and November 2020 was performed at a single institution in France. Follow up occurred from 1 month to 4 years (median 15 months). The treatment consisted of dilation with a balloon or stent. We analyzed short-term (technical success and complications) and long-term outcomes (liver function, arterial patency, graft survival at 12 months (GS), and reintervention). We also compared percutaneous balloon angioplasty (PBA) with stent placement. PBA alone was used if < 30% residual stenosis of the hepatic artery was achieved. Stenting was performed if there was greater than 30% residual stenosis and in the case of complications (dissection or rupture). RESULTS A total of 18 stenoses were suspected on the basis of routine surveillance duplex ultrasound imaging (peak systolic velocity > 200 cm/s, systolic accelerating time > 10 ms and resistive index < 0.5), all of which were confirmed by angio CT, but only 17 were confirmed by angiography. Seventeen patients were included (14 males, mean age 57 years; and three females, mean age 58 years). Interventions were performed in 17 cases (95%) with PBA only (5/17), stent only (5/17) or both (4/17). Immediate technical success was 100%. Major complications occurred in 1 of 17 cases (5.8%), consisting of target vessel dissection. The analysis of the three (groups PBA only, stent only or both) showed the same procedural success (100%), GS (100%) and normal liver function after the procedures but different rates of complications (20% vs. 0% vs. 0%), arterial patency at 12 months (60% vs. 80% vs. 85%) (p = 0.4), early stenosis (40% vs. 80% vs. 0%) or late stenosis (60% vs. 20% vs. 100%) and requirement for reintervention (40% vs. 20% vs. 14%) (p = 0.56). CONCLUSION This study suggests that PBA, stent, or both procedures show the same primary patency at 12 months. It is probably not a definitive answer, but these treatments are safe and effective for extending graft survival in the context of graft shortages.

Abstract
BACKGROUND For the accurate positioning of surgical tools, conventional intraoperative navigation systems have been developed to recognize the relationship between target positions and the tools. However, since an internal organ is deformed during the operation, registratin between real-time two-dimensional (2D) ultrasound images and three-dimensional (3D) CT or MRI images is not always effective. Therefore, this study developed image registration between 2D and 3D ultrasound images considering deformation for tracking target vessel movement in the liver. METHODS 3D ultrasound image was obtained in advance with 3D coordinates, including the target vessel. Then real-time 2D images and ultrasound probe position were simultaneously acquired using a 3D position sensor. We applied multiple image resolution registration, where rapid and fine optimizations can be expected in higher and lower levels, respectively. Meanwhile, gradient descent method was adopted for the optimization, which determines the relative arrangements to obtain maximum similarity between 2D and 3D images. We experimentally established resolution level parameters using a phantom before applying it to track liver blood vessel movements in a normal healthy subject. RESULTS Comparing between the 2D images and the registered images, although the approach has some limitations in tracking large displacement, we confirmed that the cross section of the target blood vessel was clearly visualized. CONCLUSION This method has a potential for an ultrasound therapy targeting blood vessels under natural respiration conditions.

Abstract
BACKGROUND Single-organ vasculitis (SOV) is characterized by inflammation of a blood vessel, affecting one organ, such as the skin, genitourinary system, or the aorta without systemic features. Gastrointestinal SOV is rare, with hepatic artery involvement reported only in two prior published cases. Herein, we presented a case of isolated hepatic artery vasculitis presenting after Pfizer-BioNTech mRNA corona virus disease 2019 (COVID-19) vaccination.
CASE SUMMARY A 50-year-old woman with hypertension presented to our Emergency Department with recurrent diffuse abdominal pain that localized to the epigastrium and emesis without diarrhea that began eight days after the second dose of the Pfizer-BioNTech COVID-19 vaccine. Blood work revealed an elevated C-reactive protein (CRP) of 19 mg/L (normal < 4.8 mg/L), alkaline phosphatase 150 U/L (normal 25-105 U/L), gamma-glutamyl transferase (GGT) 45 U/L (normal < 43 U/L) and elevated immunoglobulins (Ig) G 18.4 g/L (normal 7-16 g/L) and IgA 4.4 g/L (normal 0.7-4 g/L). An abdominal computed tomography revealed findings in keeping with hepatic artery vasculitis. A detailed review of her history and examination did not reveal infectious or systemic autoimmune causes of her presentation. An extensive autoimmune panel was unremarkable. COVID-19 polymerase chain reaction nasopharyngeal swab, human immunodeficiency virus, viral hepatitis and Heliobacter pylori serology were negative. At six months, the patient’s symptoms, and blood work spontaneously normalized.
CONCLUSION High clinical suspicion of SOV is required for diagnosis in patients with acute abdominal pain and dyspepsia.

Abstract
PURPOSE Arterial irrigation of the liver is highly variable and widely studied due to its importance in the correct planification of the surgical or endovascular treatment of the hepatobilary area. Various classifications have been published of the common and uncommon anatomic variations of the hepatic arterial distribution. While the classic anatomic pattern of the proper hepatic artery-when it originates from the celiac trunk dividing into left and right branches-represents 50-83% of the described patterns, there are numerous uncommon distributions based on the presence of replaced or accessory hepatic arteries. In this article, we present a case of a replaced right hepatic artery originating from the right distal renal artery. METHODS Contrast enhanced computed tomography (CECT) examination was performed on a 67 years-old male patient with compensated alcoholic cirrhosis as part of the disease monitoring. RESULTS The replaced right hepatic artery of the patient arises from the right distal renal artery and-after its cranial course-enters the porta hepatis posterior to the main portal vein. After giving off the cystic artery, it irrigates the right hepatic lobe. The left hepatic artery does not show any variation. CONCLUSION We present CT angiography images of an extremely rare anatomic variation of the hepatic arterial irrigation in a cirrhotic patient.

Abstract
Introduction The knowledge of anatomy is essential for surgical safety and impacts positively on patients' outcomes. Surgeons operating on the liver and bile ducts should keep in mind the normal anatomy and its variations as the latter are common. Case Presentation We conducted a structured surgical dissection course of the supra-colic compartment of the abdominal cavity on 2nd and 3rd October 2020. While dissecting a 46years-old male cadaver, we encountered unusual anatomical variations of the hepatic arterial branching, the biliary tree, and arterial supply to the common bile duct. The common hepatic artery was dividing into two branches: a common short trunk for the left hepatic artery and the right gastric artery (hepato-gastric trunk) and a common trunk for the right hepatic artery and gastroduodenal artery (hepato-gastroduodenal trunk). The right hepatic duct was duplicated with a main right hepatic duct and an additional smaller duct. The bile duct was supplied by an artery coming from the abdominal aorta. Conclusion We described three unusual anatomical variations: a variation of the hepatic arteries branching pattern, an aberrant right hepatic duct, and blood supply to the bile duct from the abdominal aorta. Surgeons should be aware of these rare variations.

Abstract
Vascular anomalies are a serendipitous finding during surgeries and diagnostic angiography. Such variations are frequently encountered in the abdominal region. These anomalies are usually asymptomatic but the presence of hepatic arterial variations may lead to injuries of the liver during surgery. The present study was conducted on 35 adult embalmed cadavers, 31 males, 4 females from August 2015 to December 2021 in the Department of Anatomy, Amrita School of Medicine, Amrita Institute of Medical Sciences, Kochi. In this study of 35 cadavers, we present 3 variants: an accessory right hepatic artery, replaced common hepatic artery, replaced common hepatic artery anastomosis with accessory left hepatic artery and an arc of Buhler. One of our variants has not yielded a precedent in literature search. We have compared these variants with Michels and Hiatt classification. It is known that different variants arise at distinct stages of embryonic development. As specialists in anatomy, we have tried to correlate the variants in our study with their embryological origins.

Abstract
BACKGROUND Hepatic artery reconstruction (HAR) for liver transplantation is crucial for successful outcomes. We evaluated transplantation outcome improvement through continual technical refinements. MATERIALS AND METHODS HAR was performed in 1448 living donor liver transplants by a single plastic surgeon from 2008 to 2020. Difficult HARs were defined as graft or recipient hepatic artery ≤2 mm, size discrepancy (≥2 to 1), multiple hepatic arteries, suboptimal quality, intimal dissection of graft or recipient hepatic artery (HA), and immediate redo during transplantation. Technique refinements include early vessel injury recognition, precise HA dissection, the use of clips to ligate branches, an oblique cut for all HARs, a modified funneling method for size discrepancy, liberal use of an alternative artery to replace a pathologic HA, and reconstruction of a second HA for grafts with dual hepatic arteries in the graft. RESULTS Difficult HARs were small HA (21.35%), size discrepancy (12.57%), multiple hepatic arteries (11.28%), suboptimal quality (31.1%), intimal dissection (20.5%), and immediate redo (5.18%). The overall hepatic artery thrombosis (HAT) rate was 3.04% in this series. The average HAT rate during the last 4 years (2017-2020) was 1.46% (6/408), which was significantly lower than the average HAT rate from 2008 to 2016 (39/1040, 3.8%) with a statistical significance (p = 0.025). Treatment for posttransplant HAT included anastomosis after trim back (9), reconstruction using alternatives (19), and nonsurgical treatment with urokinase (9). CONCLUSION Careful examination of the HA under surgical microscope and selection of the appropriate recipient HA are key to successful reconstruction. Through continual technical refinements, we can reduce HA complications to the lowest degree.

Abstract
PURPOSE Atypical variants of the hepatic artery are common and pose a technical challenge for normothermic machine perfusion (NMP). The transplant surgeon has three options when confronted with hepatic arterial variation in a liver graft to be subjected to NMP: to perform arterial reconstruction (i) prior, (ii) during, or (iii) following NMP. METHODS Herein, we report our experience and technical considerations with pre-NMP reconstruction. Out of 52 livers, 9 had an atypical hepatic artery (HA): 3 replaced right HA, 3 replaced left HA, 1 accessory left HA, 1 accessory left and right HA, and 1 replaced left and right HA. RESULTS Reconstruction was conducted during back-table preparation. A single vascular conduit was created in all grafts to allow single arterial cannulation for NMP, necessitating only one arterial anastomosis within the recipient. All grafts were subjected to NMP and subsequently successfully transplanted. CONCLUSION Our approach is being advocated for as it preserves the ability to alter the reconstruction in case of problems resulting from the reconstruction itself, thereby allowing functional evaluation of the reconstruction prior transplantation, permitting simultaneous reperfusion in the recipient, and providing the shortest possible duration for vascular reconstruction once the graft is rewarming non-perfused within the recipient. In addition, in light of the frequency of technically demanding reconstructions with very small vessels, we consider our technique beneficial as the procedure can be performed under ideal conditions at the back-table.

Abstract
BACKGROUND Recently, hepatic arterial infusion chemotherapy (HAIC) plus lenvatinib has been frequently used to treat unresectable hepatocellular carcinoma (uHCC) in China. In the clinic, the hepatic arteries of some patients shrink significantly during this treatment, leading to improved short-term efficacy.
AIM To investigate the relationship between the shrinkage of hepatic arteries and the short-term effect of HAIC plus lenvatinib treatment.
METHODS Sixty-seven participants with uHCC were enrolled in this retrospective study. The patients received HAIC every 3 wk, followed by oral lenvatinib after the first HAIC course. Hepatic artery diameters were measured on CT before treatment and after 1 and 2 mo of treatment. Meanwhile, the changes in tumor capillaries were also examined on pathological specimens before and after 1 mo of treatment. The antitumor response after 1, 3, and 6 mo of treatment was assessed using the modified Response Evaluation Criteria in Solid Tumors (mRECIST). The relationship between the changes in vessel diameters and the short-term effect of the combination treatment was evaluated by receiver-operating characteristic and logistic regression analyses.
RESULTS The hepatic artery diameters were all significantly decreased after 1 and 2 mo of treatment (P < 0.001), but there was no difference in the vessel diameters between 1 and 2 mo (P > 0.05). The microvessel density in the tumor lesions decreased significantly after 1 mo of combination treatment (P < 0.001). According to mRECIST, 46, 41, and 24 patients had complete or partial responses after 1, 3, and 6 mo of treatment, respectively, whereas 21, 21, and 32 patients had a stable or progressive disease at these times, respectively. Shrinkage of the tumor-feeding artery was significantly associated with the tumor response after 1, 3, and 6 mo of treatment (P < 0.001, P = 0.004, and P = 0.023, respectively); however, changes in other hepatic arteries were not significantly associated with the tumor response. Furthermore, shrinkage of the tumor-feeding artery was an independent factor for treatment efficacy (P = 0.001, P = 0.001, and P = 0.002 and 1, 3, and 6 mo, respectively).
CONCLUSION The hepatic arteries shrank rapidly after treatment with HAIC plus lenvatinib, and shrinkage of the tumor-feeding artery diameter was closely related to improved short-term efficacy.

Abstract
Background Surgical treatment is currently the only way to achieve the clinical cure for Klatskin tumor. However, whether combined vascular resection should be combined during surgeries is still controversial. The aim of this article was to analyze the effect of portal vein resection (PVR) and hepatic artery resection (HAR) on the long-term survival after surgery for Klatskin tumor. Methods Articles about Klatskin tumor with PVR and HAR, which were published from 2000 to 2020, were searched using PubMed, Embase, and EBSCO. HR with a 95% CI of overall survival, recurrence-free survival, disease-free survival, 3- and 5-year survival rate, and median survival time were reported to evaluate prognosis. Results A total of 17 articles were included. The total case number of these studies was 3150 (685 in the PVR group, 345 in the HAR group, and 2120 in the control group). Survival analyses showed that both vascular resection types were poor prognostic factors (PVR: HR = 1.50, 95% CI = 1.24–1.81, P < 0.001; HAR: HR = 1.68, 95% CI = 1.26–2.24, P < 0.001; the pooled effect size of the two groups: HR = 1.55, 95% CI = 1.32–1.82, P < 0.001). In general, the analyses of 3- and 5-year survival and median survival time showed that both vascular resection types tended to be poor prognostic factors, but most of recent researches showed that the PVR did not lead to a poor prognosis. Conclusion PVR should be used when necessary to achieve R0 resection of Klatskin tumor and improve the long-term survival of patients. Whether HAR should be performed or not is still need to be evaluated.

Abstract
A 59-year-old man presented to our surgical clinic with a long-standing history of heart burn, and upper abdominal pain. Gastroscopy showed a large sliding hiatus hernia associated with severe reflux oesophagitis. Oesophageal pH manometry revealed a high DeMeester score of 36.03. A computed tomography (CT) scan was performed for preoperative hiatal hernia repair planning. This showed the incidental finding of an accessory left hepatic artery (ALHA) and an aneurysm of this accessory artery. The aneurysm occurred at the point where the ALHA traversed the diaphragmatic crus and was only present in association with the hiatus hernia. These observations suggest that the aetiology of the aneurysm was due to traction during development of the hiatus hernia. The patient went onto have a laparoscopic hiatus hernia repair and Toupet fundoplication with ligation of the accessory left hepatic artery and made an excellent recovery. ALHAs are not uncommon, occurring in around 15% of the general population, with aneurysms of the hepatic arteries accounting for about 20% of cases of visceral artery aneurysms. The case presented herein highlights the importance of performing an arterial phase CT when planning surgery for large hiatus hernias to detect more cases like this one. This would allow early detection and concurrent treatment of an associated aneurysm with repair of the hiatus hernia, to prevent aneurysmal complications later on.

Abstract
The anatomical structure of the pancreaticoduodenal region is complex and closely related to the surrounding vessels. A variant of the hepatic artery, which is not a rare finding during pancreatic surgery, is prone to intraoperative injury. Inadvertent injury to the hepatic artery may affect liver perfusion, resulting in necrosis, liver abscess, and even liver failure. The preoperative identification of hepatic artery variations, detailed planning of the surgical approach, careful intraoperative dissection, and proper management of the damaged artery are important for preventing hepatic hypoperfusion. Nevertheless, despite the potential risks, planned artery resection has become acceptable in carefully selected patients. Arterial reconstruction is sometimes essential to prevent postoperative ischemic complications and can be performed using various methods. The complexity of procedures such as pancreatectomy with en bloc celiac axis resection may be mitigated by the presence of an aberrant right hepatic artery or a common hepatic artery originating from the superior mesenteric artery. Here, we comprehensively reviewed the anatomical basis of hepatic artery variation, its incidence, and its effect on the surgical and oncological outcomes after pancreatic resection. In addition, we provide recommendations for the prevention and management of hepatic artery injury and liver hypoperfusion. Overall, the hepatic artery variant may not worsen surgical and oncological outcomes if it is accurately identified pre-operatively and appropriately managed intraoperatively.

Abstract
PURPOSE To assess the accuracy, sensitivity, positive predictive value (PPV) and interobserver agreement of a virtual injection (VI) software that simulates selective arterial injection from nonselective cone-beam CT (CBCT) arteriography. METHODS From March 2019 to May 2020, 20 consecutive patients in whom a nonselective injected CBCT and a selective CT angiography (CTA) were completed in the same procedure, were retrospectively included. The position of the microcatheter tip used for selective CTA injection was identified. The VI was simulated from the exact same point on the nonselective CBCT and the two volumes were merged. VI was compared to the real injection on the selective CTA. Three interventional radiologists evaluated the accuracy using a 6-point scale (Perfect; Good; Fair; Incorrect Origin; False Negative; Non existing). Sensitivity, PPV, and Fleiss' kappa were calculated. Numerical variables were presented as means ± standard deviations. RESULTS Twenty procedures and 195 vessel segments were analyzed. Most vessels were 4th order (57/195; 29%) and 5th order (96/195; 49%). VI was classified as perfect to good in 96.8% ± 1.4 of 1st-3rd order arteries and in 83.4% ± 0.4 of 4th-5th order arteries. Interobserver agreement was substantial (Fleiss' kappa = 0.79; 95% confidence interval = 0.73-0.84, P < 0.01). False negatives were reported with a mean of 9.4% ± 0.3. Average sensitivity was 90.6% ± 0.3 and average PPV was 92.7% ± 0.02. Fourteen false positives were noted. CONCLUSION CBCT-based VI software accurately simulated distal injections in the liver with high sensitivity and a substantial interobserver agreement.

Abstract
BACKGROUND The role of the hepatic nervous system in liver development remains unclear. We previously created functional human micro-hepatic tissue in mice by co-culturing human hepatic endodermal cells with endothelial and mesenchymal cells. However, they lacked Glisson’s sheath [the portal tract (PT)]. The PT consists of branches of the hepatic artery (HA), portal vein, and intrahepatic bile duct (IHBD), collectively called the portal triad, together with autonomic nerves.
AIM To evaluate the development of the mouse hepatic nervous network in the PT using immunohistochemistry.
METHODS Liver samples from C57BL/6J mice were harvested at different developmental time periods, from embryonic day (E) 10.5 to postnatal day (P) 56. Thin sections of the surface cut through the hepatic hilus were examined using protein gene product 9.5 (PGP9.5) and cytokeratin 19 (CK19) antibodies, markers of nerve fibers (NFs), and biliary epithelial cells (BECs), respectively. The numbers of NFs and IHBDs were separately counted in a PT around the hepatic hilus (center) and the peripheral area (periphery) of the liver, comparing the average values between the center and the periphery at each developmental stage. NF-IHBD and NF-HA contacts in a PT were counted, and their relationship was quantified. SRY-related high mobility group-box gene 9 (SOX9), another BEC marker; hepatocyte nuclear factor 4α (HNF4α), a marker of hepatocytes; and Jagged-1, a Notch ligand, were also immunostained to observe the PT development.
RESULTS HNF4α was expressed in the nucleus, and Jagged-1 was diffusely positive in the primitive liver at E10.5; however, the PGP9.5 and CK19 were negative in the fetal liver. SOX9-positive cells were scattered in the periportal area in the liver at E12.5. The Jagged-1 was mainly expressed in the periportal tissue, and the number of SOX9-positive cells increased at E16.5. SOX9-positive cells constructed the ductal plate and primitive IHBDs mainly at the center, and SOX-9-positive IHBDs partly acquired CK19 positivity at the same period. PGP9.5-positive bodies were first found at E16.5 and HAs were first found at P0 in the periportal tissue of the center. Therefore, primitive PT structures were first constructed at P0 in the center. Along with remodeling of the periportal tissue, the number of CK19-positive IHBDs and PGP9.5-positive NFs gradually increased, and PTs were also formed in the periphery until P5. The numbers of NFs and IHBDs were significantly higher in the center than in the periphery from E16.5 to P5. The numbers of NFs and IHBDs reached the adult level at P28, with decreased differences between the center and periphery. NFs associated more frequently with HAs than IHBDs in PTs at the early phase after birth, after which the number of NF-IHBD contacts gradually increased.
CONCLUSION Mouse hepatic NFs first emerge at the center just before birth and extend toward the periphery. The interaction between NFs and IHBDs or HAs plays important roles in the morphogenesis of PT structure.

Abstract
OBJECTIVE To investigate whether the diagnostic performance of CT angiography (CTA) could be improved by modifying the conventional criterion (anastomosis site abnormality) to diagnose hepatic artery occlusion (HAO) after liver transplantation (LT) in suspected patients with Doppler ultrasound (US) abnormalities. MATERIALS AND METHODS One hundred thirty-four adult LT recipients (88 males and 46 females; mean age, 52.7 years) with suspected HAO on Doppler US (40 HAO and 94 non-HAO according to the reference standards) were included. We evaluated 1) abnormalities in the HA anastomosis, categorized as a cutoff, ≥ 50% stenosis at the anastomotic site, or diffuse stenosis at both graft and recipient sides around the anastomosis, and 2) abnormalities in the distal run-off, including invisibility or irregular, faint, and discontinuous enhancement. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the conventional (considering anastomosis site abnormalities alone) and modified CTA criteria (abnormalities in both the anastomosis site and distal run-off) for the diagnosis of HAO were calculated and compared using the McNemar test. RESULTS By using the conventional criterion to diagnose HAO, the sensitivity, specificity, PPV, NPV, and accuracy were 100% (40/40), 74.5% (70/94), 62.5% (40/64), 100% (70/70), and 82.1% (110/134), respectively. The modified criterion for diagnosing HAO showed significantly increased specificity (93.6%, 88/94) and accuracy (93.3%, 125/134) compared to that with the conventional criterion (p = 0.001 and 0.002, respectively), although the sensitivity (92.5%, 37/40) decreased slightly without statistical significance (p = 0.250). CONCLUSION The modified criterion considering abnormalities in both the anastomosis site and distal run-off improved the diagnostic performance of CTA for HAO in suspected patients with Doppler US abnormalities, particularly by increasing the specificity.

Abstract
Radiological embolization is the treatment of choice in adults with visceral artery pseudoaneurysm (PSA) and gastrointestinal bleeding, but pediatric data is scanty. We analyzed the etiology, clinical presentation, and outcome of radiological intervention in children with PSA of celiac (CA) or superior mesenteric artery (SMA) branches. Electronic records of children with PSA of CA or SMA branches were reviewed and data on clinical and laboratory profile, radiological intervention, and outcome was recorded. Eleven children with PSA (5 boys, 11 [7-17] years) were studied. Etiology was liver abscess (n 4), abdominal trauma (n 3), pancreatitis (n 3), and indeterminate in 1 case. Ten (91%) patients were symptomatic: abdominal pain (10, 91%), hematemesis/melena (9, 81%), and Quincke's triad (1, 9%). One child with pancreatic pseudocyst was diagnosed incidentally on imaging. Doppler ultrasound identified PSA only in 3 cases, while computed tomography angiography (CTA) picked all cases. Children with liver abscess, trauma, and unknown etiology had PSA from CA (right hepatic artery 7, left hepatic artery 1). Of the 3 pancreatitis cases, 2 had PSA from SMA (inferior pancreatico-duodenal artery and ileal branch) and 1 from CA (left gastric artery). Radiological embolization was done in 9 (81%) cases (coil 6, glue 2, both 1), without any complications or failure. One case resolved spontaneously and 1 died pre-intervention. Nine intervened cases were asymptomatic in follow-up [6 (1-24) months].Conclusion: Liver abscess, trauma, and pancreatitis are causes of PSA of CA and SMA branches in children. A majority present with gastrointestinal bleeding and are identified on CTA. Radiological embolization was safe with 100% success. What is Known: • Pseudoaneurysm of visceral artery is an uncommon cause of gastrointestinal bleeding. • Endoluminal intervention is an established and efficacious treatment modality in adults and preferred over surgery. What is New: • Liver abscess, abdominal trauma and pancreatitis are common causes of celiac artery and superior mesenteric artery branch pseudoaneurysm in children and computed tomography angiography has high sensitivity in identifying these pseudoaneurysms. • Minimally invasive radiological angio-embolization, in the hands of trained radiologists, is a safe and successful modality of treatment in children.

Abstract
BACKGROUND Large hepatocellular carcinoma (HCC) treatment options have obvious limitations. Our trial comprises ipsilateral hepatic artery ligation and extrahepatic collaterals division (HALED, reinforced by percutaneous tumor injection controlling residual HCC arterial supply. We aimed to evaluate the long term safety and feasibility of the Combined Surgical and Injection of alcohol Treatment (COSIT) as a novel therapy for the large HCC. MATERIAL AND METHODS Candidates' clinical data of the of this case series were prospectively and sequentially reported in accordance with stage 2a development IDEAL (Idea, Development, Exploration, Assessment and Long-term monitoring) recommendations. It included adult patients with HCC (diameter >5 cm) subjected to COSIT coming to our center during a five years' trial evaluating the long term outcome measures. Study ID (NCT03138044 ClinicalTrials.gov). RESULTS Patients were 21, their mean age (±standard deviation) was 61·9 (±9·3) years. Eleven (52.4%) patients had tumors diameter >10 cm. 17 (80.9%) patients were advanced BCLC stage. Six modifications were made in this injection phase till it came to a stability. The mean alcohol volume was 72.0 mls. The mean follow-up duration was 16 months. The median overall survival duration was 14 months. The one, three and five years' survival was 71.4%, 23.8% and 4.8%, respectively. Grade 3/4 and 4 Common Toxicity Criteria for Adverse Effects (v4.03) were encountered in 10 (47.6%) and one (4.8%) patients, respectively. CONCLUSION This preliminary findings of COSIT can be a promising alternative treatment for patients having large HCC. Consequently, a multicenter stage 2b Exploration IDEAL trial is suggested.

Abstract
Purpose To investigate efficacy and patency status of stent graft implantation in the treatment of hepatic artery pseudoaneurysm. Materials and Methods A retrospective analysis of patients who had undergone endovascular treatment of hepatic artery pseudoaneurysms between 2011 and 2020 was performed. Medical records were examined to obtain patients’ surgical histories and to screen for active bleeding. Angiographic data on vascular access, target vessel, material used and technical success, defined as the exclusion of the pseudoaneurysm by means of a stent graft with sufficient control of bleeding, were collected. Vessel patency at follow-up CT was analyzed and classified as short-term (< 6 weeks), mid-term (between 6 weeks and 1 year), and long-term patency (> 1 year). In case of stent occlusion, collateralization and signs of hepatic hypoperfusion were examined. Results In total, 30 patients were included and of these, 25 and 5 had undergone stent graft implantation and coiling, respectively. In patients with implanted stent grafts, technical success was achieved in 23/25 patients (92%). Follow-up CT scans were available in 16 patients, showing stent graft patency in 9/16 patients (56%). Short-term, mid-term, and long-term short-term stent patency was found in 81% (13/16), 40% (4/10), and 50% (2/4). In patients with stent graft occlusion, 86% (6/7) exhibited maintenance of arterial liver perfusion via collaterals and 14% (1/7) exhibited liver abscess during follow-up. Conclusion Stent graft provides an effective treatment for hepatic artery pseudoaneurysms. Even though patency rates decreased as a function of time, stent occlusion was mainly asymptomatic due to sufficient collateralization.

Abstract
OBJECTIVE This study aims to evaluate the effectiveness and safety of hepatic arterial infusion chemotherapy (HAIC) following the simultaneous placement of self-expandable metallic stent (SEMS) and iodine-125 (125I) seed strands for the management of advanced cholangiocarcinoma (CCA) patients presenting with malignant obstructive jaundice (MOJ). METHODS Data from 74 patients with MOJ caused by advanced CCA treated with stent placement with 125I seed strands with or without HAIC between November 2015 and October 2020 were analysed retrospectively. Eighteen patients received 5 sessions of HAIC after SEMS placement with 125I seed strands (HAIC group), and 56 patients only underwent SEMS placement with 125I seed strands and served as controls (control group). HAIC consisted of infusions of gemcitabine (600-1000 mg/m2 given over 30 min) followed by oxaliplatin (60-100 mg/m2 given over 2 h), with an interval of 4 weeks. Propensity score matching (PSM) analysis was used to adjust for differences in the baseline characteristics of the groups (including age, total bilirubin, and serum alanine aminotransferase level). Overall survival (OS), stent patency, and adverse events were compared between the two groups. RESULTS OS and stent patency were significantly better in patients in the HAIC group than in those in the control group (median survival time: before PSM, 362 vs. 185 days, p = 0.005; after PSM, 357 vs. 183 days, p = 0.012; median duration of stent patency: before PSM, 294 vs. 156 days, p = 0.001; after PSM, 287 vs. 183 days, p = 0.039). All adverse reactions were controllable by temporary symptomatic treatment. Serious complications and treatment-related deaths were not observed. CONCLUSION Our preliminary study showed that HAIC following SEMS placement with 125I seed strands is effective and safe for the management of advanced CCA patients presenting with MOJ and could improve stent patency and patient survival.

Abstract
BACKGROUND The hepatic artery (HA) is one of the most threatened vascular structures during hepatopancreatobiliary (HPB) surgeries and interventional procedures. It can be affected by many clinical pictures, especially tumors, due to its anatomical position and neighborhood.
AIM To reveal the evolution and recent developments in the management of HA traumas in the light of the literature.
METHODS In this article, 100 years of MEDLINE (PubMed) literature and articles including cases and series of HA injuries were reviewed, and the types of injury occurrence, treatment, and related complications and their management were compiled.
RESULTS The risk of HA injury increases during cholecystectomies and pancreatoduodenectomies, among the most common operations. HA anatomy shows anomalies in approximately 15%-25% of the cases, further increasing this risk. The incidence of HA injury is not precisely known. Approaches that have evolved in recent years in managing patients with HA injury (laceration, transection, ligation, resection) with severe morbidity and mortality risk are reviewed in light of the current literature.
CONCLUSION In conclusion, complications and deaths due to HA injury are less common today. The risk of complications increases in patients with hemodynamic instability, jaundice, cholangitis, and sepsis. Revealing the variations in the preoperative radiological evaluation will reduce the risks. In cases where HA injury is detected, arterial flow continuity should be tried to maintain with primary anastomosis, arterial transpositions, or grafts. In cases where bile duct injury develops, patients should be directed to HPB surgery centers, considering the possibility of accompanying HA injury. Large-scale and multicentric studies are needed to understand better the early and long-term results of HA ligation and determine preventive procedures.

Abstract
The presence of hepatic vascular anomalies may add challenges to an already difficult surgery such as pancreatoduodenectomy, particularly when performed laparoscopically. Thus, our aim was to assess the impact of an aberrant right hepatic artery (aRHA) on postoperative outcomes during laparoscopic pancreatoduodenectomy (LPD) . Data of patients who underwent LPD were prospectively gathered and retrospectively analyzed. Patients with types III, IV, VI, VII, VIII, and IX anomalies according to Michels' classification were included in the aRHA group and were compared with the remaining patients (nRHA group). 72 patients underwent LPD; 14 of these had an aRHA (19.4%). Except for BMI (p = 0.021), the two groups did not differ in terms of clinico-pathological characteristics. The two groups had similar postoperative complications (p = 0.123), pancreatic fistula (p = 0.790), biliary leakage (p = 0.209), postpancreatectomy hemorrhage (p = 0.790), reoperations (p = 0.416), and mortality (p = 0.312). The median number of lymph nodes harvested was higher in aRHA group (p = 0.032), while R0 resection rate was similar between groups (p = 0.635). At the multivariate analysis, only moderate/high FRS (OR 3.95, p = 0.039) was an independent predictor of postoperative complications. This study suggests that aRHA has no negative impact on surgical and oncological outcomes in patients undergoing LPD.

Abstract
Background Hemobilia refers to bleeding into the biliary tract. Hepatic artery pseudoaneurysm (HAP) rupture is an uncommon cause of hemobilia, and cases of HAP associated with Mirizzi syndrome are extremely rare. Although transarterial embolization is recommended as the first-line treatment for hemobilia, surgery is sometimes required. Case presentation A 76-year-old woman was referred to our hospital with epigastric pain. She was febrile and had conjunctival icterus and epigastric tenderness. Laboratory tests revealed abnormal white blood cell count and liver function. An abdominal computed tomography (CT) revealed multiple calculi in the gallbladder, an incarcerated calculus in the cystic duct, and a slightly dilated common hepatic duct. Based on examination findings, she was diagnosed with Mirizzi syndrome type I, complicated by cholangitis. Intravenous antibiotics were administered, and we performed endoscopic retrograde cholangiopancreatography (ERCP) to place a drainage tube. The fever persisted; therefore, contrast-enhanced CT (CECT) was performed. This revealed portal vein thrombosis and hepatic abscesses; therefore, heparin infusion was administered. The following day, she complained of melena, and laboratory tests showed that she was anemic. ERCP was performed to change the drainage tube in the bile duct; however, bleeding from the papilla of Vater was observed. CECT demonstrated a right HAP with high-density fluid in the gallbladder and gallbladder perforation. Finally, she was diagnosed with hemobilia caused by HAP rupture, and emergency surgery was performed to secure hemostasis and control the infection. During laparotomy, we found that a right HAP had ruptured into the gallbladder. The gallbladder made a cholecystobiliary fistula, which indicated Mirizzi syndrome type II. Although we tried to repair the right hepatic artery, we later ligated it due to arterial wall vulnerability. Then, we performed subtotal cholecystectomy and inserted a T-tube into the common bile duct. There were no postoperative complications except for minor leakage from the T-tube insertion site. The patient was discharged after a total hospital stay of 7 weeks. Conclusions We experienced an extremely rare case of emergency definitive surgery for hemobilia due to HAP rupture complicated by Mirizzi syndrome type II. Surgery might be indicated when controlling underlying infections was required.

Abstract
PURPOSE Preoperative hypertrophy induction of future liver remnant (FLR) reduces the risk of postoperative liver insufficiency after partial hepatectomy. One of the most commonly used methods to induce hypertrophy of FLR is portal vein embolization (PVE). Recent studies have shown that transarterial radioembolization (TARE) also induces hypertrophy of the contralateral liver lobe. The aim of our study was to evaluate contralateral hypertrophy after TARE versus after PVE taking into account the effect of cirrhosis. METHODS Forty-nine patients undergoing PVE before hemihepatectomy and 24 patients with TARE as palliative treatment for liver malignancy were retrospectively included. Semi-automated volumetry of the FLR/contralateral liver lobe before and after intervention (20 to 65 days) was performed on CT or MRI, and the relative increase in volume was calculated. Cirrhosis was evaluated independently by two radiologists on CT/MRI, and interrater reliability was calculated. RESULTS Hypertrophy after PVE was significantly more pronounced than after TARE (25.3% vs. 7.4%; p < 0.001). In the subgroup of patients without cirrhosis, the difference was also statistically significant (25.9% vs. 8.6%; p = 0.002), whereas in patients with cirrhosis, the difference was not statistically significant (18.2% vs. 7.4%; p = 0.212). After PVE, hypertrophy in patients without cirrhosis was more pronounced than in patients with cirrhosis (25.9% vs. 18.2%; p = 0.203), while after TARE, hypertrophy was comparable in patients with and without cirrhosis (7.4% vs. 8.6%; p = 0.928). CONCLUSION TARE induces less pronounced hypertrophy of the FLR compared to PVE. Cirrhosis seems to be less of a limiting factor for hypertrophy after TARE, compared to PVE.

Abstract
Mycotic aneurysms are sometimes seen in patients with infective endocarditis. We report a case of infective endocarditis with multiple mycotic aneurysms. Although antibiotics were effective, mycotic aneurysms appeared in the cerebral, hepatic, and gastroepiploic arteries. A 55-year-old man presented with mitral valve endocarditis due to Streptococcus oralis. Surgical treatment was deferred because of cerebral hemorrhage. After antibiotic initiation, his fever and C-reactive protein levels declined, and blood culture was negative. However, he experienced repeated cerebral hemorrhage and the number of cerebral mycotic aneurysms increased. Additionally, his spleen ruptured and the number of mycotic aneurysms in the hepatic and gastroepiploic arteries increased. After embolization for mycotic aneurysm and mitral valve replacement, no mycotic aneurysms appeared. Regardless of whether laboratory data improve or not, multiple mycotic aneurysms sometimes appear, and cardiac surgery for infection control should be considered in the early phase.

Abstract
OBJECTIVE To compare the diagnostic performance of three CT criteria and two signs in evaluating hepatic arterial invasion by hilar cholangiocarcinoma. METHODS In this study, we retrospectively reviewed the CT images of 85 patients with hilar cholangiocarcinoma. Modified Loyer's, Lu's, and Li's standards were used to evaluate hepatic arterial invasion by hilar cholangiocarcinoma with the reference of intraoperative findings and/or the postoperative pathological diagnosis. Arterial tortuosity and contact length were also evaluated. RESULTS Loyer's, Lu's, and Li's standards showed sensitivities of 91.7%, 90.3%, and 72.2%, specificities of 94.0%, 94.5%, and 95.6%, and accuracies of 93.3%, 93.3%, and 89.0%, respectively, in evaluating hepatic arterial invasion by hilar cholangiocarcinoma. Loyer's and Lu's standards and contact length performed better than Li's standard (P < 0.001). Arterial tortuosity performed worse than other criteria (P < 0.001). The CT criteria performed best in evaluating proper hepatic arterial invasion compared with the left and right hepatic artery. When the cut-off contact length of 6.73 mm was combined with Loyer's standard, 4 false-negative cases could be avoided. CONCLUSIONS Loyer's and Lu's standards and the contact length performed best in evaluating hepatic arterial invasion by hilar cholangiocarcinoma on preoperative CT images, particularly in assessing the proper hepatic artery. Arterial tortuosity could serve as an important supplement. The combination of the contact length and Loyer's standard could improve the diagnostic performance.

Abstract
Background/Aims Sorafenib is the first approved systemic treatment for advanced hepatocellular carcinoma (HCC). However, its clinical utility is limited, especially in Asian countries. Several reports have suggested the survival benefits of hepatic arterial infusion chemotherapy (HAIC) for advanced HCC with main portal vein tumor thrombosis (PVTT). This study aimed to compare the efficacy of sorafenib-based therapy with that of HAIC-based therapy for advanced HCC with main PVTT. Methods Advanced HCC patients with main PVTT treated with sorafenib or HAIC between 2008 and 2016 at Korea University Medical Center were included. We evaluated overall survival (OS), time-to-progression (TTP), and the disease control rate (DCR). Results Seventy-three patients were treated with sorafenib (n=35) or HAIC (n=38). Baseline characteristics were not significantly different between groups, except the presence of solid organ metastasis (46% vs 5.3%, p<0.001). The median OS time was not significantly different between the groups (6.4 months vs 10.0 months, p=0.139). TTP was longer in the HAIC group than in the sorafenib group (2.1 months vs 6.2 months, p=0.006). The DCR was also better in the HAIC group than in the sorafenib group (37% vs 76%, p=0.001). Subgroup analysis, which excluded patients with extrahepatic solid organ metastasis, showed the same trends for the median OS time (8.8 months vs 11.1 months, p=0.097), TTP (1.9 months vs 6.0 months, p<0.001), and DCR (53% vs 81%, p=0.030). Conclusions HAIC-based therapy may be an alternative to sorafenib for advanced HCC with main PVTT by providing longer TTP and a better DCR. (Gut Liver 2021;15-294)

Abstract
PURPOSE No consensus exists on whether to preserve or ligate an aberrant left hepatic artery (ALHA), which is the most commonly encountered hepatic arterial variation during gastric surgery. Therefore, we aimed to evaluate the clinical effects of ALHA ligation by analyzing the perioperative outcomes. MATERIALS AND METHODS We retrospectively reviewed the data of 5,310 patients who underwent subtotal/total gastrectomy for gastric cancer. Patients in whom the ALHA was ligated (n=486) were categorized into 2 groups according to peak aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels: moderate-to-severe (MS) elevation (≥5 times the upper limit of normal [ULN]; MS group, n=42) and no-to-mild (NM) elevation (<5 times the ULN; NM group, n=444). The groups were matched 1:3 using propensity score-matching analysis to minimize confounding factors that can affect the perioperative outcomes. RESULTS The mean operation time (P=0.646) and blood loss amount (P=0.937) were similar between the 2 groups. The length of hospital stay was longer in the MS group (13.0 vs. 7.8 days, P=0.022). No postoperative mortality occurred. The incidence of grade ≥ IIIa postoperative complications (19.0% vs. 5.1%, P=0.001), especially pulmonary complications (11.9% vs. 2.5%, P=0.003), was significantly higher in the MS group. This group also showed a higher Comprehensive Complication Index (29.0 vs. 13.9, P<0.001). CONCLUSIONS Among patients with a ligated ALHA, those with peak AST/ALT ≥5 times the ULN showed worse perioperative outcomes in terms of hospital stay and severity of complications. More precise perioperative decision-making tools are needed to better determine whether to preserve or ligate an ALHA.

Abstract
PURPOSE Aberrant hepatic artery anatomy is a considerable challenge during pancreatic surgery as it warrants extreme caution for the preservation of vascular supply as well as achievement of R0 resection margin. METHOD We reviewed the literature about the aberrant anatomical variations of the hepatic artery and its relevance during pancreatoduodenectomy and distal pancreatectomy. RESULT Preoperative deliberation of peri-pancreatic vascular anatomy using advanced imaging methods is crucial for surgeons. At the same time, intra-operative suspicion and early identification of aberrant anatomy may help to prevent vascular injury and related complications. Yet, vascular reconstruction may be needed in many situations; several techniques like pre-operative embolization provide new options for management in specific situations. CONCLUSION We have provided here an overview of the anatomical variants of the hepatic artery and their implication during pancreatoduodenectomy and distal pancreatectomy.

Abstract
Background and Aims: Long-term data on cell-based therapies, including hematopoietic stem cell infusion in cirrhosis, are sparse and lacking. Methods: Patients with cirrhosis of non-viral etiology received either standard-of-care (n = 23) or autologous CD34+ cell infusion through the hepatic artery (n = 22). Study patients received granulocyte colony-stimulating factor (commonly known as G-CSF) injections at 520 µgm per day for 3 days, followed by leukapheresis and CD34+ cell infusion into the hepatic artery. The Control group received standard-of-care treatment. Results: Mean CD34+ cell count on the third day of G-CSF injection was 27.00 ± 20.43 cells/µL 81.84 ± 11.99 viability and purity of 80-90%. Significant improvement in the model of end-stage liver disease (commonly known as MELD) score (15.75 ± 5.13 vs. 19.94 ± 6.68, p = 0.04) was noted at end of 3 months and 1 year (15.5 ± 5.3 vs. 19.8 ± 6.4, p = 0.04) but was not statistically different at end of the second (17.2 ± 5.5 vs. 20.3 ± 6.8, p = 0.17) and third-year (18.4 ± 6.1 vs. 21.3 ± 6.4, p = 0.25). No difference in mortality (6/23 vs. 5/23) was noted. Conclusions: Autologous CD34+ cell infusion effectively improved liver function and MELD score up to 1 year but the sustained benefit was not maintained at the end of 3 years, possibly due to ongoing progression of the underlying disease.
