A sharp interface Lagrangian-Eulerian method for flexible-body fluid-structure interaction [PDF]
, 2022 This paper introduces a sharp-interface approach to simulating fluid-structure interaction involving flexible bodies described by general nonlinear material models and across a broad range of mass density ratios. This new flexible-body immersed Lagrangian-Eulerian (ILE) approach incorporates the geometrical and domain solution flexibility of the ...

Numerical and experimental study of the fluid flow through a medical device [PDF]
, 2015 The purpose of this paper is to verify a commercial software based fluid–structure interaction scheme for the inferior vena cava. Vena cava deep thrombosis (TVP) is a potentially deathly disease consequent to pulmonary thromboembolism (TEP).

Wilms tumor with inferior vena cava duplication: a rare case report
BMC Urology, 2018 Background Wilms tumor is the most common renal tumor of childhood. Duplication of the inferior vena cava is an uncommon anomaly. In the present study, we present a case of Wilms tumor with the inferior vena cava duplication, which has not been reported ...

Agenesis of the Inferior Vena Cava
Revista Brasileira de Cardiologia Invasiva (English Edition), 2012 ABSTRACTAgenesis of the inferior vena cava is a rare malformation. Its most common cause is dysgenesis during embryogenesis, but it may also be related to intrauterine or perinatal thrombosis. It is usually asymptomatic, associated or not with other congenital malformations and may be related to increased risk of chronic venous insufficiency and deep ...

Residual Aligner Network [PDF]
, 2022 Image registration is important for medical imaging, the estimation of the spatial transformation between different images. Many previous studies have used learning-based methods for coarse-to-fine registration to efficiently perform 3D image registration.

JACC: Cardiovascular Interventions, 2013 Venous thromboembolism is common. Most pulmonary emboli arise as thromboses in the deep veins of the lower extremities and may result in serious complications. Inferior vena cava filters (IVCF) are intended to prevent the passage of deep vein thrombosis to the pulmonary arteries.

A quantitative model for refilling of the sarcoplasmic reticulum during vascular smooth muscle asynchronous [Ca2+] oscillations [PDF]
Cell Calcium 42, 565-75 (2007), 2006 We have developed a quantitative model for the creation of cytoplasmic Ca2+ gradients near the inner surface of the plasma membrane (PM). In particular we simulated the refilling of the sarcoplasmic reticulum (SR) via PM-SR junctions during asynchronous [Ca2+] oscillations in smooth muscle cells of the rabbit inferior vena cava.

Journal of Clinical Ultrasound, Volume 51, Issue 1, Page 5-15, January 2023., 2023 Exercise intolerance is a common complication in long‐term survivors of allogeneic hematopoietic stem‐cell transplantation. In this study, we found reduced oxygen uptake (VO2peak) by cardio‐pulmonary exercise tests to be associated with left ventricular systolic dysfunction by echocardiography.

Total laparoscopic retrieval of inferior vena cava filter
SAGE Open Medical Case Reports, 2015 While there is some local variability in the use of inferior vena cava filters and there has been some evolution in the indications for filter placement over time, inferior vena cava filters remain a standard option for pulmonary embolism prophylaxis ...
