Deep learning-driven pulmonary artery and vein segmentation reveals demography-associated vasculature anatomical differences. [PDF]
Nat CommunPulmonary artery-vein segmentation is crucial for disease diagnosis and surgical planning and is traditionally achieved by Computed Tomography Pulmonary Angiography (CTPA). However, concerns regarding adverse health effects from contrast agents used in CTPA have constrained its clinical utility.

Pulmonary artery aneurysm: a review
Pulmonary Circulation, 2020 Pulmonary artery aneurysm is a rare but important entity in the spectrum of pulmonary vascular diseases. The etiologies can be varied and patients can present with non-specific symptoms with the diagnosis being incidental.

A multiscale model of vascular function in chronic thromboembolic pulmonary hypertension [PDF]
, 2021 Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by recurrent or unresolved pulmonary thromboemboli, leading to perfusion defects and increased arterial wave reflections. CTEPH treatment aims to reduce pulmonary arterial pressure and reestablish adequate lung perfusion, yet patients with distal lesions are inoperable by standard surgical

Pulmonary artery pulsatility index: physiological basis and clinical application
European Journal of Heart Failure, 2019 Pulmonary artery pulsatility index (PAPi) is a haemodynamic parameter that is derived from right atrial and pulmonary artery pulse pressures. A number of reports have described the prognostic value of PAPi in patients with advanced heart failure and ...

Pulmonary artery size as a predictor of outcomes in idiopathic pulmonary fibrosis
European Respiratory Journal, 2016 IPF patients have heightened propensity for pulmonary hypertension, which portends a worse outcome. Presence of pulmonary hypertension may be reflected in an enlarged pulmonary artery.

Aneurysms of the Pulmonary Artery
Circulation, 2015 Pulmonary artery (PA) aneurysms (PAAs) are rare and infrequently diagnosed. Deterling and Clagett1 discovered 8 cases of PAAs in 109 571 consecutive postmortem examinations.

A Topological Data Analysis Study on Murine Pulmonary Arterial Trees with Pulmonary Hypertension [PDF]
arXiv, 2022 Pulmonary hypertension (PH), defined by a mean pulmonary arterial blood pressure above 20 mmHg, is a cardiovascular disease impacting the pulmonary vasculature. PH is accompanied by vascular remodeling, wherein vessels become stiffer, large vessels dilate, and smaller vessels constrict.

Automatic Pulmonary Artery-Vein Separation in CT Images using Twin-Pipe Network and Topology Reconstruction [PDF]
arXiv, 2021 With the development of medical computer-aided diagnostic systems, pulmonary artery-vein(A/V) separation plays a crucial role in assisting doctors in preoperative planning for lung cancer surgery. However, distinguishing arterial from venous irrigation in chest CT images remains a challenge due to the similarity and complex structure of the arteries ...
