α‐Adrenergic blockade impairs ductus venosus shunting during an acute period of fetal hypoxaemia without further deficits to cerebral oxygen delivery

Experimental Physiology, Volume 111, Issue 4, Page 1796-1807, 1 April 2026.
Abstract The fetal circulation has unique shunts, including the ductus venosus (DV), the tone of which dictates how much substrate‐rich blood returning from the placenta is streamed preferentially away from the liver and instead towards the heart. Herein, we aimed to use clinically relevant MRI techniques in sheep to measure indirectly induced changes ...

The relationship between Doppler indices from inferior vena cava and hepatic veins in normal human fetuses. [PDF]

, 2003
This study was conducted to determine the gestational age-related reference range of the preload index [peak velocity during atrial contraction (A)/peak velocity during ventricular systole (S)] for the inferior vena cava (IVC), the right hepatic vein ...

Acute cardio‐centric haemodynamic management preserves chronic cardiovascular function in pigs with high‐thoracic spinal cord injury

The Journal of Physiology, Volume 604, Issue 7, Page 2659-2682, 1 April 2026.
Abstract figure legend Recent work has shown that treating the reduction in heart function following acute spinal cord injury (SCI) better optimizes peripheral haemodynamics and spinal cord oxygenation than the standard approach of using vasopressors.

Unique Constellation of Vascular Anomalies in a Female Cadaver: IVC, Renal Vein, and Left Colic Artery Variation

Surgeries
Embryological development of the vascular system consists of growth and regression of developing vessels, often resulting in numerous variations. This cadaveric case report describes an individual with a duplicated inferior vena cava accompanied by ...

Congenital systemic venous return anomalies to the right atrium review

Insights into Imaging, 2019
Congenital anomalies of the systemic venous return to the right atrium are rare and stem from variations in the embryogenesis of the venous system. They are usually asymptomatic, and such the major clinical significance of their recognition is to prevent

The helpful support of veno‐arterial extracorporeal membrane oxygenation to treat an exceptional systemic‐to‐pulmonary venous shunt: A case report

Physiological Reports, Volume 14, Issue 7, April 2026.
Abstract Systemic‐to‐pulmonary venous shunting is a rare cause of refractory hypoxemia. Its prompt recognition is crucial, as management requires not only etiological treatment but also the restoration of physiological venous return. We report the case of a 40‐year‐old man presenting with dyspnea, cervicothoracic edema, and hypoxemia.

Augmented venous return for minimally invasive open heart surgery with selective caval cannulation [PDF]

, 2017
Objective: Minimally invasive open heart surgery involves limited intrathoracic cannulation sites necessitating cardiopulmonary bypass to be initiated via peripheral access using percutaneous cannulae with the tip placed into the right atrial cavity ...

Conjoined Parasitic Twins (Cephalo‐Thoracopagus Parasiticus) in a Free Ranging Northern Bat (Eptesicus nilssonii): A Micro‐CT Anatomic and Genetic Survey

Anatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The detailed anatomical situation of male stillborn cephalo‐thoracopagus twins in a wild ranging northern bat (Eptesicus nilssonii) is described by means of full body micro‐CT scans in high resolution with three‐dimensional computational reconstruction.
