Case Description: 3 dogs were examined because of Budd-Chiari syndrome (BCS), which is an obstruction of venous blood flow located between the liver and the junction of the caudal vena cava and right atrium. Two dogs had confirmed neoplastic obstructions, and the other dog had a suspected neoplastic obstruction of the hepatic veins and caudal vena cava.
Clinical Findings: All dogs had similar clinical signs of weight gain, lethargy, and ascites that did not respond to medical treatments, and 2 dogs had pitting edema of the hind limbs. Ultrasonography revealed a presumptive venous obstruction, which was confirmed by use of computed tomography.
Treatment And Outcome: Each dog was anesthetized. By use of fluoroscopic guidance, endovascular stents were placed within the left hepatic vein and caudal vena cava in 2 dogs, and a single stent was placed within the left hepatic vein extending into the caudal vena cava of the third dog. After stent placement, venous pressure in the left hepatic vein decreased. Resolution of clinical signs was dramatic in all 3 dogs (survival time ranged from 7 to 20 months), with only mild complications in 1 dog.
Clinical Relevance: Endovascular stents may be an appropriate palliative treatment for dogs with clinical signs attributable to BCS.

Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study.
World J Gastroenterol

Department of Hepatobiliary Surgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing 400000, China.
Background: Laparoscopic liver resection (LLR) can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy. Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization, tumor compression, and bleeding from the short hepatic veins (SHVs). This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava (IVC), allowing SHVs to be addressed after parenchymal transection, thereby reducing surgical complexity and improving outcomes in in situ LLR.

Introduction: The proliferation of nanoplastics (NPs) has emerged as a significant environmental concern due to their extensive use, raising concerns about potential adverse effects on human health. However, the exact impacts of NPs on the early development of hematopoietic organs remain poorly understood.
Methods: This investigation utilized fluorescence microscopy to observe the effects of various NP concentrations on the caudal vein plexus (CVP) development in zebrafish embryos.

Objectives: The primary objective of this investigation was to ultrasonographically evaluate the caudal vena cava to aorta (CVC:Ao) ratio in healthy, conscious cats and to generate reference intervals. A secondary objective was to identify the site of examination with the least intra- and inter-observer variability. This investigation was undertaken to assess whether the CVC:Ao ratio holds promise as a technique to assess intravascular volume responsiveness in cats.

Computed tomographic (CT) characterisation of abdominal vessels is poorly studied. The objectives of this retrospective study were to assess during growth, by CT angiography, the evolution of the aorta (Ao), caudal vena cava (CVC), portal vein (PV), length of the second lumbar vertebra (L2) and different ratios between these structures; and to determine the influence of weight and age on the vessels' sizes and ratios. The first group included six beagles scanned every month from 4 to 12 months old, then every 3 months up to 24 months old.
