For coronary artery bypass grafting (CABG), a ‘no-touch’ technique to harvest the saphenous vein graft has been considered superior to the conventional approach. Surprisingly, a new study comes to a different conclusion.
Using a melt electrowriting (MEW) technique, bioengineers have developed a hybrid structure to address the clinical need for small-diameter vascular grafts and help combat cardiovascular disease.
Using vascular organoids derived from stem cells, researchers gain new insights into how diabetes damages blood vessels. This could lead to to the development of new treatments.
Microbubbles in a contrast agent allows for ultrasound imaging of the finest vascular details. This is the working principle of a technique called ultrasound localization microscopy (ULM).
Researchers were able to produce sub-millimetre resolution images of cardiac micro-vessels. This non-invasive new technique could allow scientists to study the physiology of the heart in more detail.
A Korean research team has advanced the imaging of kidney diseases using ultrafast ultrasound that captures 1,000 images in just one second.
Dutch researchers successfully inserted magnet-controlled miniature robots into an aorta model with kidneys. In the future, this technology could be used to remove blood clots.
Using AI and optoacoustic imaging, researchers have developed a new method to assess microvascular changes in the skin – and thus the severity of diabetes in the patient.
Using small blood vessels grown in the lab, researchers discover how vascular leaks leading to dementia and stroke emerge – and how this damage might be fixed.
New technology that creates ultra-thin layers of human cells in tube-like structures could spur development of lifelike blood vessels and intestines in the lab.
Patients with heart disease could benefit from less extensive interventions thanks to technology that creates 3D computer models of blood flow through the heart's arteries, according to new research.
MRI-derived wall shear stress values predict pathological changes in the aortic wall in patients with ascending aortic dilatation. This can help identfy at-risk patients.
German researchers present a novel method for testing chemical agents that could help in the development of drugs against neurodegenerative diseases such as Alzheimer's.
Researchers at McMaster University create device to replicate conditions in blood vessels after grafts.
Similar to the way exercise helps muscles adapt to workouts, short, repeated bouts of reduced circulation with a blood pressure cuff may help prevent the worst outcomes of heart attacks and strokes.
Advances in image post-processing and contrast-enhanced techniques have widened the scope of possibilities for MRI and ultrasound vascular imaging, experts showed in a dedicated course at the ECR Overture.
An international team has for the first time demonstrated that nerve signals are exchanged between clogged up arteries and the brain.
3D-printed sugar models of dense and chaotic blood vessel networks near tumors could help future cancer treatments.
French researchers have found a way to facilitate access to tumours for killer lymphocytes, paving the way for more efficient immunotherapies against cancer.
