The common hepatic artery aneurysms (HAA) are uncommon atherosclerotic lesions and often they are clinically silent. Their diagnosis is often difficult prior to rupture, due to nonspecific clinical presentation. We report a case of a giant aneurysm of the common hepatic artery causing obstructive jaundice through compression of the biliary tract. The presence of the lesion was confirmed with the use of spiral computed tomographic angiography. Hepatic artery aneurysm is a lesion that should be considered in cases of unexplained obstructive jaundice.

The impact of vascular injuries on the management of bile duct injury following laparoscopic cholecystectomy- insights from a prospective study.
HPB (Oxford)
January 2025
Department of Surgical Gastroenterology, All India Institute of Medical Sciences, Patna, India.
Background: Our study aimed to compare the clinical presentation and outcomes of post-cholecystectomy bile duct injuries (BDI) with and without arterial injuries.
Methods: A prospective analysis of 123 patients with post-cholecystectomy BDI between July 2018 and January 2022 was performed. Multivariate logistic regression analysis was used to assess the impact of vascular injuries on perioperative complications and long-term outcomes after delayed repair.
Total Pancreatectomy for Locally Advanced Pancreatic Adenocarcinoma with Coeliac Trunk Resection and Retrograde Gastric Revascularization Through Aorto-Hepato-Spleno Allograft.

Background: Locally advanced pancreatic adenocarcinomas (LA-PDAC) are more frequently operated now than in the past because of new regimen chemotherapy and improvement in surgical technique. Resection of the coeliac trunk (CT) during pancreatoduodenectomy (PD) or total pancreatectomy (TP) is not routinely done owing to the risk of liver and gastric ischaemia. In this video, a patient with LA-PDAC underwent TP with CT resection and retrograde gastric revascularization through the distal splenic artery.

J Clin Gastroenterol
November 2024
Departments of Gastroenterology.
Introduction And Objectives: The portal vein pressure higher than 10 mm Hg in patients with hepatic cirrhosis is more likely to have serious complications and poor prognosis. Nonselective receptor blockers (NSBBs) can reduce the portal vein pressure; however, the efficacy and safety of different NSBBs in reducing portal vein pressure were unconsistent. A systematic review and meta-analysis was conducted to evaluate the efficacy and safety of carvedilol versus propranolol in reducing portal vein pressure in this study.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by the presence of at least one cardiovascular disease (CVD) risk factor, underscoring its potential to elevate CVD risk in affected individuals. However, evidence linking MASLD to subclinical coronary atherosclerosis remains scarce, and further investigations are necessary to elucidate the independent role of varying MASLD severities as a CVD risk factor.
Methods: This study analyzed 7,507 participants aged ≥ 40 who underwent comprehensive health evaluations at the Shanghai Health and Medical Center.
The pan-PPAR agonist lanifibranor reduces portal pressure independent of fibrosis reduction through the splanchnic vasculature.

Portal hypertension (PH) can cause severe complications in patients with advanced chronic liver disease (aCLD). The pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist lanifibranor reduces portal pressure in preclinical models of aCLD. Since the effect on PH might be secondary to fibrosis improvement, we investigated the effect of lanifibranor on PH, hepatic and splanchnic angiogenesis in mouse models of fibrotic and prehepatic non-fibrotic PH.
