Canadian Journal of Anaesthesia, 1991 Infantile pyloric stenosis is the most frequently encountered infant gastrointestinal obstruction in most general hospitals. Although the primary therapy for pyloric stenosis is surgical, it is essential to realize that pyloric stenosis is a medical and not a surgical emergency.

European Journal of Echocardiography, 2005 Aortic stenosis is a common finding at echocardiography. This review describes the assessment of the aortic valve, the left ventricle, and the rest of the heart. It discusses grading the stenosis including cases in which there are discrepancies between the different echocardiographic measurements.

The effect of varying degrees of stenosis on transition to turbulence in oscillatory flows [PDF]
arXiv, 2022 Many complications in physiology are associated with a deviation in flow in arteries due to a stenosis. The presence of stenosis may transition the flow to weak turbulence. The degree of stenosis as well as its configuration whether symmetric or non-symmetric to the parent artery influences whether the flow would stay laminar or transition to ...

Automated Detection of Coronary Artery Stenosis in X-ray Angiography using Deep Neural Networks [PDF]
arXiv, 2021 Coronary artery disease leading up to stenosis, the partial or total blocking of coronary arteries, is a severe condition that affects millions of patients each year. Automated identification and classification of stenosis severity from minimally invasive procedures would be of great clinical value, but existing methods do not match the accuracy of ...

StenUNet: Automatic Stenosis Detection from X-ray Coronary Angiography [PDF]
arXiv, 2023 Coronary angiography continues to serve as the primary method for diagnosing coronary artery disease (CAD), which is the leading global cause of mortality. The severity of CAD is quantified by the location, degree of narrowing (stenosis), and number of arteries involved.

SSASS: Semi-Supervised Approach for Stenosis Segmentation [PDF]
arXiv, 2023 Coronary artery stenosis is a critical health risk, and its precise identification in Coronary Angiography (CAG) can significantly aid medical practitioners in accurately evaluating the severity of a patient's condition. The complexity of coronary artery structures combined with the inherent noise in X-ray images poses a considerable challenge to this ...

Two New Stenosis Detection Methods of Coronary Angiograms [PDF]
arXiv, 2021 Coronary angiography is the "gold standard" for diagnosing coronary artery disease (CAD). At present, the methods for detecting and evaluating coronary artery stenosis cannot satisfy the clinical needs, e.g., there is no prior study of detecting stenoses in prespecified vessel segments, which is necessary in clinical practice.

A Recurrent CNN for Automatic Detection and Classification of Coronary Artery Plaque and Stenosis in Coronary CT Angiography [PDF]
, 2018 Various types of atherosclerotic plaque and varying grades of stenosis could lead to different management of patients with coronary artery disease. Therefore, it is crucial to detect and classify the type of coronary artery plaque, as well as to detect and determine the degree of coronary artery stenosis.
