Drug-Eluting or Bare-Metal Stents for Coronary Artery Disease.

New England Journal of Medicine, 2016
BACKGROUND Limited data are available on the long-term effects of contemporary drug-eluting stents versus contemporary bare-metal stents on rates of death, myocardial infarction, repeat revascularization, and stent thrombosis and on quality of life ...

Prediction of need for bowel resection in acute superior mesenteric artery occlusion: A retrospective study of 48 Japanese patients

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 175-181, January 2023., 2023
In a study of 48 patients with acute superior mesenteric artery occlusion, a logistic regression model using time from onset to diagnosis and the occlusion site of superior mesenteric artery showed 78.6% sensitivity in ruling out cases requiring bowel resection.

Simulation of bifurcated stent grafts to treat abdominal aortic aneurysms (AAA) [PDF]

, 2016
In this paper a method is introduced, to visualize bifurcated stent grafts in CT-Data. The aim is to improve therapy planning for minimal invasive treatment of abdominal aortic aneurysms (AAA). Due to precise measurement of the abdominal aortic aneurysm and exact simulation of the bifurcated stent graft, physicians are supported in choosing a suitable ...

Prediction of stent under-expansion in calcified coronary arteries using machine-learning on intravascular optical coherence tomography [PDF]

arXiv, 2022
BACKGROUND Careful evaluation of the risk of stent under-expansions before the intervention will aid treatment planning, including the application of a pre-stent plaque modification strategy. OBJECTIVES It remains challenging to achieve a proper stent expansion in the presence of severely calcified coronary lesions.

The increased main branch to stent diameter ratio is associated with side branch decreased coronary flow in "true" coronary artery bifurcations treated by "provisional" stenting - a two-dimensional quantitative coronary angiography study [PDF]

Vojnosanitetski Pregled, 2020
Background/Aim. Percutaneous coronary interventions (PCI) in bifurcation lesions having more than 50% stenosis of both the main branch (MB) and the side branch (SB) remain challenging.

Accuracy of Length of Virtual Stents in Treatment of Intracranial Wide-Necked Aneurysms. [PDF]

, 2019
Background and purposePrecise stent deployment is important for successful treatment of intracranial aneurysms by stent-assisted coiling (SAC). We evaluated the accuracy of virtual stents generated using commercial stent planning software by comparing ...

Pharmacokinetic analysis after implantation of everolimus-eluting self-expanding stents in the peripheral vasculature [PDF]

, 2012
Background: A novel self-expanding drug-eluting stent was designed to release everolimus 225 mu g/cm(2) to prevent restenosis following peripheral arterial intervention.

3D-Printed PCL/PLA Composite Stents: Towards a New Solution to Cardiovascular Problems

Materials, 2018
Biodegradable stents (BRS) offer enormous potential but first they must meet five specific requirements: (i) their manufacturing process must be precise; (ii) degradation should have minimal toxicity; (iii) the rate of degradation should match the ...

In Silico Fatigue Optimization of TAVR Stent Designs with Physiological Motion in a Beating Heart Model [PDF]

arXiv, 2023
The rapid expansion of TAVR to younger, low-risk patients raises concerns regarding device durability. Necessarily, extended stent lifetime will become more critical for new generation devices. In vitro methods commonly used for TAVR stent fatigue testing exclude the effects of the beating heart.

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal
