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…
Royal Philips announced that it has signed an agreement to acquire Intact Vascular, Inc., a U.S.-based developer of medical devices for minimally-invasive peripheral vascular procedures. Intact Vascular will enhance Philips’ image-guided therapy portfolio, combining Philips’ interventional imaging platform and diagnostic and therapeutic devices with Intact Vascular’s unique, specialized…
In the world of laboratory diagnostics, ‘Abbott’ is a household name. Few people however are aware of the fact that the company, headquartered in Illinois, USA, is also leading in other fields. A number of innovations in cardiac and vascular diagnostics and therapy might soon put Abbott in the limelight. Dr Angela Germer, Regional Director DACH, and Volker Keller, Head of Marketing DACH,…
A new technique could enable vascular surgeons to reach even the more difficult body regions. Instead of pushing catheters into minute veins, the system, devised in Canada by Professor Sylvain Martel and team at the Polytechnique Montréal Nanorobotics Laboratory, uses magnetic forces to pull a guidewire, or catheter, into remote physical locations, guiding medical instruments into narrow and…
Interventional radiotherapy for tibial arteries has increased in recent years. Why? People are getting older and better techniques and materials now permit treatment even of very thin vessels. Professor Dierk Vorwerk, Director of the Institute for Radiology at Ingolstadt Hospital, where almost a third of all interventions in his department are performed on the lower leg, described the most…
Patients with the rare Loeys-Dietz syndrome suffer from aortic enlargement which may result in sudden over-expansion and a fatal aortic tear. In order to prevent this from happening, an aortic prosthesis must be implanted. A team of vascular surgeons at the University Hospital of Zurich was one of the first in the world to risk undertaking this life-saving operation on a child as an emergency…
