Double Mesh Nitinol Stent Versus Self-expanding Stent-graft in Recurrent/Resistant Cephalic Vein Arch Stenoses in Dialysis Fistulae: A Comparative Study
AbstractPurposeTo compare the double mesh nitinol stent (DNS) versus the self-expanding stent-graft (SES) in recurrent/resistant cephalic vein arch stenosis in dialysis fistulae.Materials and Methods17 cases with recurrent/resistant stenosis of the cephalic vein arch treated with a DNS were compared retrospectively with 18 cases treated with an SES. Stenting was performed either for significant recoil post-angioplasty with high-pressure balloons or in recurrent stenoses. Patients were followed up with Doppler ultrasound in our vascular access surveillance programme. Primary and assisted primary patency rates at 3, 6 and 12...

Digital Variance Angiography in Lower-Limb Angiography with Metal Implants
AbstractPurposeThe presence of metal implants may reduce angiographic image quality due to automated beam adjustments. Digital variance angiography (DVA) is reported to be superior to digital subtraction angiography (DSA) with increased contrast-to-noise ratio (CNR) and better image quality. The aim of the study was to evaluate whether DVA could counterbalance the image quality impairment of lower-limb angiographies with metal implants.Materials and MethodsFrom November 2019 to January 2020, 85 raw lower-limb iodine contrast angiograms of 12 patients with metal implants were processed retrospectively with DVA analyses.

Biomechanics of the Osseous Pelvis and Its Implication for Consolidative Treatments in Interventional Oncology
AbstractThe osseous pelvis is a frequent site of metastases. Alteration of bone integrity may lead to pain but also to functional disability and pathological fractures. Percutaneous image-guided minimally invasive procedures, such as cementoplasty and screw fixation, have emerged as a viable option to provide bone reinforcement and fracture fixation, as stand-alone or combined techniques. Understanding the biomechanics of the osseous pelvis is paramount to tailor the treatment to the clinical situation. The purpose of the present review is to present the biomechanics of the osseous pelvis and discuss its implication for th...

Transcatheter Embolization of Renal –Splenic Shunt to Treat Hematemesis
We report a case of a patient without portal hypertension, but with bleeding gastric varices with a presumed splenorenal shunt (SRS) on CT. Venography revealed flow  reversal through the shunt (directed from the renal vein, into the splenic vein and out the portal vein; a renal-splent shunt (RSR)) and thus an anatomically similar but functionally distinct systemic to mesenteric variant. While being anatomically similar to the well-known SRS, the different flow dynamics necessitate a different approach for treatment and important considerations for the use of any liquid embolic.

AbstractAcute aortic syndrome, aortic aneurysm and stenotic aortic disease are significant challenges for state-of-the art imaging of the aorta. Over the last decade, advanced imaging methods such as multidetector computed tomography, high-resolution ultrasound including color-coded Doppler and contrast-enhanced B-mode imaging and magnetic resonance imaging have assumed an important role in identifying and describing many of the complex aortic pathologies. They play a fundamental role in decision making for treatment such as endovascular, or open surgical or conservative treatment. In this overview, a systematic descriptio...
