Patients with Marfan syndrome have an increased risk of life-threatening aortic complications, mostly preceded by aortic dilatation. Treatment with losartan, an angiotensin-II receptor-1 blocker, may reduce aortic dilatation rate in Marfan patients. In this multicentre, open-label, randomized controlled trial with blinded assessments, we compared losartan treatment with no additional treatment ...

Non invasive vascular elastography (NIVE) was developed to highlight atherosclerotic plaque constituents. However, NIVE motion estimates are affected by artifacts, such as an underestimation of deformations due to projected movement angles with respect to the ultrasound beam, movements of the operator or of the patient during image acquisition. The main ...

Peripancreatic artery aneurysms are a rare condition, representing <2% of all splanchnic artery aneurysms, and have been significantly related to celiac axis stenosis. While they are most often asymptomatic, those aneurysms have a strong tendency to rupture (52% rupture rate at the initial presentation) and, in this case, the outcome ...

Untreated large vessel occlusions lead to high rates of mortality and morbidity in ischemic stroke. The 'recanalization hypothesis' posits that timely restoration of flow in the ischemic area leads to improved clinical outcomes by salvaging the underperfused and threatened tissue (penumbra). Intravenous thrombolysis is the first-line treatment for reperfusion but ...
