Title: Is Celiac Trunk Revascularization Necessary After High-Flow Pancreaticoduodenal Arterial Arcades Aneurysm Retrograde Embolization?

High-flow pancreaticoduodenal artery (PDA) aneurysms secondary to celiac trunk occlusion or stenosis have a high risk of rupture. Embolization offers a less invasive alternative to surgery. We evaluated the effectiveness and safety of retrograde embolization via the superior mesenteric artery of high-flow PDA aneurysms without celiac trunk revascularization.

Selective internal radiation therapy across Barcelona Clinic Liver Cancer (BCLC) stages of hepatocellular carcinoma: literature review.

Background And Objective: Selective internal radiation therapy (SIRT) represents an endovascular treatment option for patients with hepatocellular carcinoma (HCC). Its use is widely recognized in the intermediate and advanced HCC, but it has become more prevalent in recent years in different Barcelona Clinic Liver Cancer (BCLC) stages. The aim of this review is to summarize the role of SIRT and its clinical implications through different stages of HCC.

The Paradox of Modern Technology in Standardizing Thermal Liver Ablation: Fostering Uniformity or Diversity?

Purpose: Currently, significant medical practice variation exists in thermal ablation (TA) of malignant liver tumors with associated differences in outcomes. The IMaging and Advanced Guidance for workflow optimization in Interventional Oncology (IMAGIO) consortium aims to integrate interventional oncology into the standard clinical pathway for cancer treatment in Europe by 2030, by development of a standardized low-complex-high-precision workflow for TA of malignant liver tumors. This study was conducted at the start of the IMAGIO project with the aim to explore the current state and future role of modern technology in TA of malignant liver tumors.

Methods: We conducted a retrospective, observational study using data collected from consecutive patients undergoing SIRT between October 2013 and June 2020.

Performance Comparison of Augmented Reality Versus Ultrasound Guidance for Puncture: A Phantom Study.

Purpose: Augmented reality (AR) is an innovative approach that could assist percutaneous procedures; by directly seeing "through" a phantom, targeting a lesion might be more intuitive than using ultrasound (US). The objective of this study was to compare the performance of experienced interventional radiologists and operators untrained in soft tissue lesion puncture using AR guidance and standard US guidance.

Material And Methods: Three trained interventional radiologists with 5-10 years of experience and three untrained operators performed punctures of five targets in an abdominal phantom, with US guidance and AR guidance.

Percutaneous image-guided management of a misplaced pericardiocentesis catheter into the inferior vena cava.

Misplacement of pericardiocentesis catheter in central veins is a rare complication that can be managed with several methods. In this case, we report a percutaneous image-guided plug-assisted management of a misplaced pericardiocentesis catheter into the inferior vena cava through a transhepatic tract successfully occluded. This minimally invasive technique was not previously described in this setting and had a favorable long-term outcome.

Preoperative Spinal Arterial Supply Mapping Using Non-Selective Cone Beam Computed Tomography before Complex Aortic Repair.

Pre-op spinal arterial mapping is crucial for complex aortic repair.

Purpose: To evaluate and compare the prevalence and type of abdominal involvements identified on CT scans in COVID-19 critically ill patients to those observed in critically ill patients with non-SARS-CoV-2 viral pneumonia.

Methods: Monocentric IRB approved retrospective study comparing all abdominal CT scans performed for patients admitted in the ICU with COVID-19 and those performed in a historical cohort of ICU patients with non-SARS-CoV-2 viral pneumonia. For each patient, gallbladder abnormality, acute pancreatitis signs, acute adrenal infarction, renal infarcts, bowel wall thickening and CT scan signs of bowel ischemia were assessed.

Utility of Early Posttreatment PET/CT Evaluation Using FDG or F-FCH to Predict Response to Y Radioembolization in Patients With Hepatocellular Carcinoma.

. Assessment of hepatocellular carcinoma (HCC) treatment response after transarterial radioembolization (TARE) is challenging, because response by conventional imaging criteria may not become apparent until 6 months after treatment. Though HCC exhibits variable avidity for FDG, some cases of HCC without avidity for FDG show avidity for F-fluorocholine (F-FCH).

The use of cardiac computed tomography angiography in the assessment of percutaneous left atrial appendage closure - Review and experts recommendations endorsed by the Société française d'imagerie cardiaque et vasculaire diagnostique et interventionnelle.

Atrial fibrillation is the most common cause of arrhythmia which is responsible for over 15% of ischemic strokes, most of these being secondary to migration of a left atrial appendage (LAA) thrombus. In patient with contraindication to anticoagulant therapy, percutaneous closure system placement may be indicated. Cardiac computed tomography (CT) angiography plays a central role in the initial assessment as well as in the follow-up.
