Dual-drainage pulmonary venous return of the left upper lobe
Annals of Pediatric CardiologyDual drainage of a pulmonary vein is an unusual anomaly of pulmonary venous drainage. While being evaluated for hypertension, a child was found with dual drainage of the upper left lobe through a vertical vein that connects to the normal pulmonary vein ...

Learning Tubule-Sensitive CNNs for Pulmonary Airway and Artery-Vein Segmentation in CT [PDF]
arXiv, 2020 Training convolutional neural networks (CNNs) for segmentation of pulmonary airway, artery, and vein is challenging due to sparse supervisory signals caused by the severe class imbalance between tubular targets and background. We present a CNNs-based method for accurate airway and artery-vein segmentation in non-contrast computed tomography.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Advanced Functional Materials, EarlyView.Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Seeking an Optimal Approach for Computer-Aided Pulmonary Embolism Detection [PDF]
arXiv, 2021 Pulmonary embolism (PE) represents a thrombus ("blood clot"), usually originating from a lower extremity vein, that travels to the blood vessels in the lung, causing vascular obstruction and in some patients, death. This disorder is commonly diagnosed using CT pulmonary angiography (CTPA).

Flow‐Induced Vascular Remodeling on‐Chip: Implications for Anti‐VEGF Therapy
Advanced Functional Materials, EarlyView.Flow‐induced vascular remodeling plays a critical role in network stabilization and function. Using a vasculature‐on‐chip system, this study reveals how physiological VEGF levels and flow affect vascular remodeling and provides insights into tumor vessel normalization.

Management of asymptomatic pulmonary vein aneurysm
Respiratory Medicine Case Reports, 2017 Aneurysm of a pulmonary vein is a rare vascular anomaly that is usually discovered incidentally as a pulmonary nodule or mediastinal mass. Most patients do not have any symptoms but some patients can present with dyspnea, hemoptysis, or cerebral ...
