6 out of 10 people develop pain after a limb amputation. Researchers now investigate whether a preventive, relatively simple nerve surgery can prevent patients from experiencing this pain.
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.
The stiffer the arteries, the greater the cardiovascular risk, according to a new study. The researchers suggest using this as a predictive tool, and emphasise the utility of a specific clinical tool.
Using light instead of x-rays, a new imaging method from Philips is designed to advance navigation through a patient's blood vessels during minimally-ivasive procedures.
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.
Cardiologists in Zurich demonstrate that immediate revascularization of non-involved blood vessels offers better outcomes for patients after a heart attack than a delayed procedure.
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.
One robot supports the surgeon’s control of tiny instruments, while another automatically keeps an eye on what is happening: With this novel combination, surgeons in Münster have successfully performed fully robot-assisted microsurgery for the first time. Presenting the new procedure at the Hornheide Specialist Clinic, the experts explain how the interaction of both robotic systems ensures…
A research group has revealed that SARS-CoV-2 disrupts the vascular endothelial barrier by suppressing the expression of Claudin-5 (CLDN5) to invade the blood vessels.
New research shows that cell-cell signaling could play a key role in the thickening of arteries due to high blood pressure.
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.
Networks adapt over time and in this way form a kind of memory. German researchers show that the structure of blood vascular network is dynamic and can adapt to external factors.
When every minute counts: A Swiss team is currently developing a diagnostic procedure that can be used to start a tailored therapy for acute stroke in a timely manner.
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.
Two successive studies highlight advances in non-invasive 3D ultrasound imaging, making it possible to observe blood flow in real time in the heart and the brain.
Recently, a Korean research team has developed a 3D foot imaging technique that vividly captures peripheral blood vessels, even thinner than 1 mm. It combines photoacoustic and ultrasound images.
A team of researchers are developing the use of an artificial intelligence (AI) algorithm with the aim of diagnosing deep vein thrombosis (DVT) more quickly and as effectively as traditional radiologist-interpreted diagnostic scans, potentially cutting down long patient waiting lists and avoiding patients unnecessarily receiving drugs to treat DVT when they don’t have it.
Researchers have found a way to reduce organ rejection following a transplant by using a special polymer to coat blood vessels on the organ to be transplanted. The polymer, developed by Prof. Dr. Jayachandran Kizhakkedathu and his team at the Centre for Blood Research and Life Sciences Institute at the University of British Columbia, substantially diminished rejection of transplants in mice when…
