Background: Hepatic artery aneurysms (HAAs) exhibit a notable risk of rupture, with both true aneurysms and pseudoaneurysms being exceptionally uncommon (incidence rate approximately 2 per 100,000). Symptoms include epigastric and right upper quadrant pain, jaundice, and potentially life-threatening bleeding upon rupture. This bleeding can extend into the portal vein, hepatic vein, biliary system, or abdominal cavity.

In human fetuses, the left hepatic artery (LHA) issues the marginal artery that runs along the umbilical vein and, sometimes, reaches the umbilicus. The further observation demonstrated that, in 5 of 12 Japanese midterm fetuses (crown-rump length mm: 46, 50, 54, 59, 102), the marginal artery issued not only a thin umbilical branch but also a liver parenchymal branch that took a posterosuperior recurrent course in a peritoneal fold and supplied the anterior surface of the liver left lobe (segment III). However, in 22 Spanish fetuses of which gestational ages corresponded to the Japanese ones, we did not find the parenchymal branch.

Schistosomiasis is a chronic and morbid disease of poverty affecting approximately 200 million people worldwide. Mature schistosome flatworms wander in the host's hepatic portal and mesenteric venous system where they encounter a range of blood flow conditions and geometrical confinement. However, the mechanisms that support schistosome locomotion and underlie the pathogen's adaptation to its physical environment are largely unknown.

Department of Radiology, Shimane University Faculty of Medicine, P.O. Box 00693-8501, 89-1 Enya cho, Izumo, Japan.
Purpose: To evaluate the differences of technique between coil embolization for short abdominal arterial segments with only proximal balloon inflation and combined proximal and distal balloon inflation, as well as the volume embolization ratio (VER) and the ratio of the first coil diameter to the target vessel diameter (first coil diameter ratio).
Materials And Methods: From January 2014 to August 2016, we performed coil embolization of the short segment in seven patients. The target vessels were the common hepatic arteries before distal pancreatectomy with en bloc celiac axis resection in five patients, the superior mesenteric artery for isolation of pseudoaneurysm in one patient and the celiac trunk for preventing Type II endoleak before endovascular aortic repair in one patient.
The Role of Mesothelial Cells in Liver Development, Injury, and Regeneration.

Mesothelial cells (MCs) cover the surface of visceral organs and the parietal walls of cavities, and they synthesize lubricating fluids to create a slippery surface that facilitates movement between organs without friction. Recent studies have indicated that MCs play active roles in liver development, fibrosis, and regeneration. During liver development, the mesoderm produces MCs that form a single epithelial layer of the mesothelium.
