Ultrasound Guided Venous Access for Cardiac Devices: Defining Learning Curve for Safety, Efficacy, and Radiation Exposure

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background There is limited real‐world experience of the learning curve for ultrasound (US) guided axillary venous access for cardiac device implantation, and it is usually performed before cutaneous incision. We investigated the learning curve, radiation exposure, safety, and efficacy of US‐guided venous access in standard workflow.

Machine learning‐based classification of varicocoele grading: A promising approach for diagnosis and treatment optimization

Andrology, Volume 13, Issue 6, Page 1451-1461, September 2025.
Abstract Background Varicocoele is a correctable cause of male infertility. Although physical examination is still being used in diagnosis and grading, it gives conflicting results when compared to ultrasonography‐based varicocoele grading. Objectives We aimed to develop a multi‐class machine learning model for the grading of varicocoeles based on ...

In Horses With Chronic Laminitis, Do Venograms Compared to Plain Radiographs Give Greater Diagnostic or Prognostic Information?

Veterinary Evidence, 2017
Clinical bottom lineThere is no conclusive evidence available to guide recommendations as to whether venograms provide any greater diagnostic or prognostic information compared to the use of plain radiographs in horses with chronic laminitis.

Comparative Analysis of Padua and Caprini Scores in Predicting Venous Thromboembolism Risk Among Nonagenarians: A Cross‐Sectional Study From Rugao

Annals of Noninvasive Electrocardiology, Volume 30, Issue 5, September 2025.
This cross‐sectional study compared the predictive performance of Padua and Caprini scores for VTE risk assessment in 511 individuals aged > 90 years from Rugao, China. ROC curve analysis revealed moderate predictive capability for both scores. The findings suggest a need for age‐specific refinement of VTE risk assessment tools and highlight the ...

Assessing Arterial Patterns in the Motor Cortex With 7 Tesla Magnetic Resonance Imaging and Vessel Distance Mapping

Human Brain Mapping, Volume 46, Issue 11, 01 August 2025.
To elucidate structural patterns in human motor cortex vascularization, vessel distance mapping (VDM) is utilized to identify vessel territories from 7 T MRI. Subsequent transformation into MNI space facilitates the creation of vessel pattern‐specific atlases, enabling noninvasive mapping of each artery's supply based on the underlying vascularization.

Diagnostic value of computerized tomography venography in detecting stenosis and occlusion of subclavian vein and superior vena in chronic renal failure patients

Electronic Physician, 2016
Introduction: Currently, venography is the standard diagnostic method to examine veins before implementing access, which is invasive in nature. Computerized tomography venography (CTV) can simultaneously indicate deep and superficial venous systems in ...

Three-Dimensional Evaluation of the Anatomic Variations of the Femoral Vein and Popliteal Vein in Relation to the Accompanying Artery by Using CT Venography

Korean Journal of Radiology, 2011
Objective We wanted to describe the three-dimensional (3D) anatomic variations of the femoral vein (FV) and popliteal vein (PV) in relation to the accompanying artery using CT venography.

Clinical feasibility of high‐power short‐duration strategy at the sites adjacent to the esophagus during laser balloon‐based pulmonary vein isolation

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
We enrolled 50 ablation sites (12, 10, 8.5, and 5.5 W) in 11 patients where the esophageal temperature reached 39°C within 5 s after ablation. Although ablation duration was correlated with power settings, total energy and maximal esophageal temperature did not differ significantly among the 4 groups.

Multi-detector computer tomography venography (MDCTV) as a diagnostic tool in the management of patients with atypical, complicated and/or recurrent varicose veins

South African Journal of Radiology, 2012
Aim. To evaluate the role of multi-detector computer tomography venography (MDCTV), compared with conventional venography, as a diagnostic tool in the management of patients with atypical, complicated and/or recurrent varicose veins.
