Chronic mesenteric ischaemia: role of interventional radiology in enhancing clinical outcomes

Chronic mesenteric ischaemia (CMI) is a progressive vascular condition where insufficient blood flow to the gastrointestinal tract leads to postprandial pain, sitophobia and weight loss. Unlike acute mesenteric ischaemia, CMI develops gradually and is often underdiagnosed due to vague symptoms and the protective role of collateral circulation. Although mesenteric arterial stenosis is common, symptomatic CMI […]

Imaging of abdominal congenital vascular anomalies in dogs and cats

This article provides a comprehensive overview of congenital vascular anomalies in the abdomen of dogs and cats, focusing primarily on portosystemic shunts (PSS) and arterioportal communications. These anomalies, though uncommon, are clinically significant and often present in young animals with symptoms such as poor growth, gastrointestinal issues and neurological signs due to toxins bypassing the […]

Innovations and developments in vascular ultrasound

The Doppler effect was first described by Christian Andreas Doppler in 1842. However, it was not until the mid-1950s that Doppler shift techniques were first used to monitor heart and peripheral blood vessel pulsations. The further development of Doppler imaging technologies with the detection of blood flow through the heart and peripheral vessels took place […]

Choosing the right calcium strategy

Vascular calcification (VC) is defined as mineral deposition in the vasculature in the form of calcium-phosphate complexes. Although VC is regarded as part of the normal ageing process, certain pathological processes such as diabetes, hypertension, chronic kidney disease (CKD) or rare hereditary disorders may also precipitate the condition. Traditionally, calcification is classified into two forms, […]

The role of radiographers in vascular access assessment and intervention

Vascular access is currently managed by various specialities, however advanced practice radiography has allowed radiographers to assume roles in the insertion, maintenance and assessment of vascular access devices (VADs). Historically radiographers have inserted VADs in interventional radiology (IR) but are often not involved in the assessment and maintenance aspects of VAD care. The introduction to […]
