Spiral Vein Graft Technique for Popliteal Artery Aneurysms [PDF]
EJVES Short Reports, 2019 In patients with popliteal artery aneurysm lacking a suitable vein for bypass, prosthetic graft, or endovascular stent graft are alternative treatment options. However, durability is limited. Construction of an autologous spiral vein graft has previously been used to replace infected aortic grafts and arteriovenous fistulas.Five patients underwent ...

Detection and localization of Coronary Arterial Lesion with the Aid of Impedance Cardiography [PDF]
arXiv, 2020 In recent years, coronary artery disease is escalating and is likely to assume an epidemic proportion by 2030. Currently the reliable methods for detection of coronary arterial lesions are either conventional coronary angiogram (CAG) or MDCT (Multiple Detector Computed Tomography) coronary angiogram.

Multiscale Mechanical Behavior of Large Arteries [PDF]
Encyclopedia of Biomedical Engineering, Elsevier, pp.180-202, 2019, 2019 The mechanical integrity of arteries is of prime importance, for a proper oxygen and nutrients delivery to all organs. To optimize their mechanical properties, healthy arteries exhibit a complex hierarchical microstructure which ensures a sufficient compliance at low stresses and which stiffens at higher stresses, preventing over-dilatation.

LES of physiological blood flow in diseased basilar artery: semi-patient specific model [PDF]
, 2013 Large Eddy Simulation (LES) is applied to study physiological pulsatile spiral and non-spiral blood flow through a model of an irregular stenosis with an adjacent post-stenotic fusiform irregular aneurysm in basilar artery.

Time trends in survival and readmission following coronary artery bypass grafting in Scotland, 1981-96: retrospective observational study [PDF]
, 2002 Improvements in coronary revascularisation techniques and an increase in the use of percutaneous interventions1 have led to a rise in the number of coronary artery bypass grafting operations in older patients with more severe cardiac disease and worse ...

Pulmonary embolism by a foreign body (polymethyl methacrylate)
Вестник хирургии имени И.И. Грекова, 2020 A rare clinical case of material pulmonary embolism is described. After 2 month of reconstructive surgery on the spine, on the chest cavity organs X-ray picture spiral solid was revealed. Surgical intervention - removal of a foreign body of the pulmonary

Numerical Assessment of Novel Helical/Spiral Grafts with Improved Hemodynamics for Distal Graft Anastomoses. [PDF]
PLoS ONE, 2016 In the present work, numerical simulations were conducted for a typical end-to-side distal graft anastomosis to assess the effects of inducing secondary flow, which is believed to remove unfavourable flow environment.

Convective infux/glymphatic system: tracers injected into the CSF enter and leave the brain along separate periarterial basement membrane pathways [PDF]
, 2018 Tracers injected into CSF pass into the brain alongside arteries and out again. This has been recently termed the "glymphatic system" that proposes tracers enter the brain along periarterial "spaces" and leave the brain along the walls of veins.
