Objective: Studies of the efficacy of nonsurgical methods of liver-directed therapy (percutaneous microwave or radiofrequency ablation, transarterial bland embolization, chemoembolization, and/or radioembolization) in the treatment of hepatocellular cancer lack contemporaneous comparative surgical cohorts. The role of these methods of liver-directed therapy as destination treatment in hepatocellular cancer is not well defined.
Methods: We queried our institutional registry for patients undergoing resection or liver-directed therapy alone for clinical stage I to IVa hepatocellular cancer between 2012 and 2022.
Pulmonary artery pseudoaneurysms are rare. We present a case of a 78-year old female who developed a pulmonary artery pseudoaneurysms causing hemoptysis after undergoing endovascular placement of a left atrial appendage occlusion device. The pulmonary arery pseudoaneurysm was treated with coil embolization.

Techniques for managing dislodged stents have included surgical, endovascular, and conservative approaches. This case details a patient who had a covered stent placed within the left renal vein which later migrated to the pulmonary artery causing damage to the tricuspid valve.

Steno-occlusive disease is a collective term that encompasses hepatic artery thrombosis, hepatic artery stenosis, and hepatic arterial kinks, while nonocclusive arterial disease encompasses less than 5% of complications and is a collective term used to describe arteriovenous fistulae, pseudoaneurysms, arterial rupture and nonocclusive hepatic artery hypoperfusion syndrome. This article details the angiographic techniques and definitions needed to accurately diagnose arterial transplant complications and describes the technical aspects and results of endoluminal management of these arterial complications.

Systemic air embolism is a very rare event but can be devastating. Prompt recognition can be difficult due to an often-vague presentation but is essential and should be considered upon rapid deterioration of a patient's status following high risk procedures.

As the number of LVP procedures performed by Interventional Radiologists continue to increase, this study was undertaken to analyze the impact of the RenovaRP® Paracentesis Management System (GI Supply) on procedure time and patient satisfaction. METHODS Between March 9, 2020 and May 29, 2020, procedural data and patient satisfaction was collected as part of a practice quality improvement project and retrospectively analyzed on 39 sequential paracenteses performed with wall suction prior to acquiring the RenovaRP® system and subsequently on 42 paracenteses performed with use of the device.

Materials And Methods: A retrospective review of all attempted fistula closures utilizing the Biodesign Fistula Plug at a single institution from 2012 to 2020 was performed under IRB approval and in compliance with HIPAA. Patient demographics were obtained including age at the time of the procedure, etiology, location of the fistula, history of malignancy, prior chemotherapy or radiation, and history of prior surgery or other interventions.
Purpose: To evaluate extracellular matrix enterocutaneous fistula plugs (ECMFPs) in treatment of enteric fistulae at a single institution.
Materials And Methods: The study included 18 patients who had an ECMFP placed between 2012 and 2018 with treatment follow-up through July 2020. Median patient age was 52.
Of all procedures in interventional radiology, percutaneous transhepatic biliary drainage (PTBD) is amongst the most technically challenging. Successful placement requires a high level of assorted skills. While this procedure can be life-saving, it can also lead to significant iatrogenic harm, often manifesting as bleeding.

Purpose: To review the available safety and efficacy data for prostatic artery embolization (PAE) in the treatment of benign prostatic hyperplasia (BPH).
Materials And Methods: PubMed was searched for publications that included PAE for the treatment of BPH through May 2015. Two independent reviewers determined the appropriateness for inclusion of each article and compiled data by using pooled weighted means and standard deviations.
During the annual 46th annual American Alliance of Academic Chief Residents in Radiology (A(3)CR(2)) meeting in New Orleans, chief residents discussed the role of residents within American College of Radiology 3.0 campaign. Our discussion was directed toward the evolving role of fourth-year radiology residents and how we might improve their training to better prepare them to add value as both leaders and radiologists.

The survey serves as a resource for observing trends and disseminating ideas among radiology training programs.
Materials And Methods: An online survey was distributed to chief residents at 181 residency programs, with questions on a broad range of topics including resident benefits, program and call structure, American Board of Radiology Core exam preparation, fellowships, and the job market.
Purpose: Our objective was to determine the efficacy and safety of image-guided, percutaneous cryoablation for American Joint Committee on Cancer pT1ANxMx and pT1BNxMx biopsy-proven renal cell carcinoma (RCC).
Materials And Methods: Computed tomography (CT)-guided, percutaneous cryoablation was used to treat 117 renal lesions in 113 consecutive patients with pT1NxMx RCC. All 117 ablations were included in the safety analysis, and complications were categorized according to Common Terminology Criteria for Adverse Events version 3.
The inherited motor neuron disease spinal muscular atrophy (SMA) is caused by mutation of the telomeric survival motor neuron 1 (SMN1) gene with retention of the centromeric SMN2 gene. We sought to establish whether the potent and specific hydroxamic acid class of histone deacetylase (HDAC) inhibitors activates SMN2 gene expression in vivo and modulates the SMA disease phenotype when delivered after disease onset. Single intraperitoneal doses of 10 mg/kg trichostatin A (TSA) in nontransgenic and SMA model mice resulted in increased levels of acetylated H3 and H4 histones and modest increases in SMN gene expression.

To develop such an approach, we applied optical computer recognition (OCR) algorithms for detecting facial changes during performance while people experienced both low- and high-stressor performance demands. Workload and social feedback were used to vary performance stress in 60 healthy adults (29 men, 31 women; mean age 30 yr).
