BACKGROUND: Image-guided insertion of stents in the upper gastrointestinal trunk is an effective, minimally invasive treatment option to provide immediate relief of symptoms caused by upper gastrointestinal tract obstruction related to advanced-stage malignant causes or benign causes that lead to lumen narrowing. PURPOSE: This document, as with all CIRSE Standards of Practice documents, is not intended to impose a standard of clinical patient care but will recommend a reasonable approach to best practices for performing stenting of the upper gastrointestinal tract, namely the oesophageal and gastroduodenal segments...

PURPOSE: To retrospectively assess the safety and efficacy of coil embolization for catheter-directed true common and proper hepatic artery aneurysm exclusion. MATERIALS AND METHODS: Nine consecutive patients (2005-2021) in two university centers presenting with true common and proper hepatic artery aneurysms (> 2 cm in diameter) were treated with 'frontdoor-backdoor' coil embolization. Patients presenting with a hepatic artery pseudoaneurysm, mycotic aneurysm or patients with small (< 2 cm diameter) aneurysms and followed up by imaging were excluded...

At present, astronauts on space missions can get medical assistant from Earth. In the future, deep space missions such as missions to Mars will delay communication with physicians on Earth, making it impossible to get immediate support in urgent medical situations. On the spaceship, a polyvalent physician-astronaut could mainly perform small surgery and traumatology procedures. Interventional Radiology (IR) allows minimally invasive interventions and requires small devices. In these conditions of space constrains, IR presents significant benefits...

BACKGROUND: Using data collected in the prospective observational study CIRSE Registry for SIR-Spheres Therapy, the present study aimed at identifying predictors of adverse events (AEs) following transarterial radioembolization (TARE) with Yttrium-90 resin microspheres for liver tumours. METHODS: We analysed 1027 patients enrolled between January 2015 and December 2017 and followed up for 24 months. Four hundred and twenty-two patients with hepatocellular carcinoma (HCC), 120 with intrahepatic carcinoma (ICC), 237 with colorectal liver metastases and 248 with liver metastases from other primaries were included...

Image-guided minimally invasive radiofrequency ablation (RFA) of sensory nerves has emerged as a treatment option for pain and swelling associated with advanced symptomatic joint and spine degeneration to bridge the gap between optimal medical therapy and surgical treatments. RFA of articular sensory nerves and the basivertebral nerve use image-guided percutaneous approaches resulting in faster recovery time and minimal risks. The current published evidence indicates clinical effectiveness; however, further research must be performed comparing other conservative treatments with RFA to understand further its role in different clinical settings, such as osteonecrosis...

PURPOSE: Decline in hemoglobin (Hgb) levels is common post-embolization, but there is no consensus on the classification of patients based on risk for re-bleeding or re-intervention. The current study evaluated post-embolization Hgb level trends with the goal of understanding the factors predictive of re-bleeding and re-intervention. MATERIALS AND METHODS: All patients who underwent embolization for gastrointestinal (GI), genitourinary, peripheral, or thoracic arterial hemorrhage from 01/2017 to 01/2022 were reviewed...

PURPOSE: To assess the tumor response rates and liver toxicity of boosted-dose transarterial radioembolization (TARE) for treatment of hepatocellular carcinoma (HCC) refractory to previous transarterial embolization (TAE) and/or chemoembolization (TACE). MATERIALS AND METHODS: All patients were identified who had HCC treated between 2017 and 2020 that had been refractory to prior TAE or TACE, then treated with boosted-dose segmental or lobar TARE. Tumor response was assessed by multiphasic CT or MRI using localized mRECIST imaging criteria and serological alpha-fetoprotein levels at three and six months after TARE, if available...

Hemodialysis access is the lifeline for end-stage renal disease patients. However, dialysis access is associated with a host of complications, including thrombosis, recurrent stenosis, infection, aneurysmal changes and bleeding. Although endovascular therapy remains the first-line treatment owing to its less invasive nature, there are certain situations where surgical referral is recommended or even necessary. Regardless, management of dialysis access complications requires a multidisciplinary approach. Interventional radiologists should be familiar with the appropriate timing for surgical referral to better serve the complex patient population...
