Topology Repairing of Disconnected Pulmonary Airways and Vessels: Baselines and a Dataset [PDF]
arXiv, 2023 Accurate segmentation of pulmonary airways and vessels is crucial for the diagnosis and treatment of pulmonary diseases. However, current deep learning approaches suffer from disconnectivity issues that hinder their clinical usefulness. To address this challenge, we propose a post-processing approach that leverages a data-driven method to repair the ...

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]
, 2002 Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

Catheter Entrapment in a Pulmonary Vein [PDF]
Chest, 2010 Ablation strategies for the treatment of atrial fibrillation (AF) are associated with several potential complications. During electro-anatomic mapping of the left atrium (LA) before ablation, the ablation catheter was entrapped in the right inferior pulmonary vein (RIPV). After multiple unsuccessful gentle tractions, stronger maneuvers with rotation of

A surprise aberrant pulmonary vein [PDF]
Interactive CardioVascular and Thoracic Surgery, 2017 We report an incidental discovery of the superior pulmonary vein coming from a strange anatomical location when performing a robotic left lower lobectomy. When trying to identify the superior pulmonary vein, an aberrant pulmonary vein was found leading into the innominate vein.

In-silico analysis of the influence of pulmonary vein configuration on left atrial haemodynamics and thrombus formation in a large cohort [PDF]
arXiv, 2022 Atrial fibrillation (AF) is considered the most common human arrhythmia. Around 99\% of thrombi in non-valvular AF are formed in the left atrial appendage (LAA). Studies suggest that abnormal LAA haemodynamics and the subsequently stagnated flow are the factors triggering clot formation.

Efficient Anatomical Labeling of Pulmonary Tree Structures via Deep Point-Graph Representation-based Implicit Fields [PDF]
, 2023 Pulmonary diseases rank prominently among the principal causes of death worldwide. Curing them will require, among other things, a better understanding of the complex 3D tree-shaped structures within the pulmonary system, such as airways, arteries, and veins.

The fifth pulmonary vein [PDF]
, 2016 A cadaver in Myungsung Medical College (MMC) had a 3rd pulmonary vein originating from the middle lobe of the right lung. Such anatomical variations are very rare. People with this variation have a total of five pulmonary veins entering left atrium.
