Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

ESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled

Differences in Right Hepatic Duct Length Among Left‐Sided Hepatectomies: Conventional Hepatectomy Versus Extended Hepatectomy Versus Trisectionectomy

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Left‐sided hepatectomy for perihilar cholangiocarcinoma includes conventional left hepatectomy (C‐LH; H1234‐B), extended left hepatectomy (E‐LH; H12345′8′‐B‐MHV), and left trisectionectomy (LT; H123458‐B). The anatomical characteristics of the resected length of the right hepatic duct (RHD) in E‐LH remain unclear.

Modification of the muscular contractility of the vena porta in trypsinemia.

Romanian journal of physiology : physiological sciences, 2004
The purpose of the present work was to investigate the changes of spontaneous and induced contractility in the rat vena porta, in conditions of acute pancreatitis, artificial trypsinemia and direct action of trypsin. The amplitude, frequency and mainly the intensity of the structure functioning decrease significantly under the influence of proteolitic ...

Hypoplasie van de vena portae bij honden

Vlaams Diergeneeskundig Tijdschrift, 2014
Hypoplasie van de vena portae (PVH) is een aangeboren afwijking waarbij intrahepatische, microscopische shunts aanwezig zijn, waardoor het bloed niet door de leversinusoïden vloeit. De klinische presentatie en laboratoriumbevindingen vertonen sterke gelijkenissen met deze van patiënten met een extrahepatische portosystemische shunt (EHPSS).

Exploring hemodynamic alterations in gastroschisis: insights into fetal growth restriction using prenatal MRI

Ultrasound in Obstetrics &Gynecology, EarlyView.
Abstract Objective Despite the high incidence of fetal growth restriction (FGR) in gastroschisis (GS) associated with placental fetal vascular malperfusion (FVM), the underlying mechanism remains unclear. We aimed to investigate whether umbilical vein (UV) stenosis at the abdominal wall defect impairs fetoplacental circulation, leading to FGR.
