Multicenter Quantification of Radiation Exposure and Associated Risks for Prostatic Artery Embolization in 1476 Patients.

Background Prostatic artery embolization (PAE) is a safe, minimally invasive angiographic procedure that effectively treats benign prostatic hyperplasia; however, PAE-related patient radiation exposure and associated risks are not completely understood. Purpose To quantify radiation dose and assess radiation-related adverse events in patients who underwent PAE at multiple centers. Materials and Methods This retrospective study included patients undergoing PAE for any indication performed by experienced operators at 10 high-volume international centers from January 2014 to May 2021.

Operator Learning Curve for Prostatic Artery Embolization and Its Impact on Outcomes in 296 Patients.

Purpose: To define operator learning curve inflection points for prostatic artery embolization (PAE) and their impact on technical efficiency, clinical outcomes, and adverse events.

Materials And Methods: Between May 2013 and May 2021, 296 consecutive patients with moderate-to-severe lower urinary tract symptoms, urinary retention, or gross hematuria from benign prostatic hyperplasia underwent PAE by an interventional radiologist without prior PAE-specific experience. Operator learning curves plotted procedure time, fluoroscopy time, contrast volume, and embolic endpoint data against sequential procedure number.

Emergency department initiated resuscitative endovascular balloon occlusion of the aorta (REBOA) for out-of-hospital cardiac arrest is feasible and associated with improvements in end-tidal carbon dioxide.

Objectives: Out-of-hospital cardiac arrest (OHCA) claims the lives of approximately 350,000 people in the United States each year. Resuscitative endovascular balloon occlusion of the aorta (REBOA) when used as an adjunct to advanced cardiac life support may improve cardio-cerebral perfusion. Our primary research objective was to determine the feasibility of emergency department (ED)-initiated REBOA for OHCA patients in an academic urban ED.

Real-Time MRI-Guided Prostate Interventions.

Prostate cancer (PCa) is the second most common cause of cancer death in males. Targeting MRI-visible lesions has led to an overall increase in the detection of clinically significant PCa compared to the prior practice of random ultrasound-guided biopsy of the prostate. Additionally, advances in MRI-guided minimally invasive focal treatments are providing new options for patients with PCa.

Page kidney: an unusual complication of image-guided native renal parenchymal biopsy - case report and literature review.

Page kidney is a pathologic phenomenon in which extrinsic compression of renal parenchyma from a subcapsular collection causes secondary systemic hypertension, via activation of the renin-angiotensin-aldosterone system. Following the first description of Page kidney, the condition was most often recognized following blunt trauma to the flank. Increasingly, non-traumatic and iatrogenic etiologies of Page kidney have been described.

Image-Guided Targeted Prostate Biopsies.

Prostate cancer is the second most common cancer in the United States. Screening for prostate cancer has increased through the usage of prostate specific antigen and biopsies. Traditionally, prostate biopsies are done using transrectal ultrasound with 10-12 cores obtained in a sextant pattern.

Voiding and Storage Domain-Specific Symptom Score Outcomes After Prostate Artery Embolization for Lower Urinary Tract Symptoms and Urinary Retention.

Objective: To characterize voiding and storage symptom domain-specific outcomes after prostate artery embolization (PAE) to treat lower urinary tract symptoms (LUTS) or urinary retention caused by benign prostatic hyperplasia (BPH).

Methods: Two hundred forty patients (age = 74.5 ± 8.

Benign Prostatic Hyperplasia: Clinical Manifestations, Imaging, and Patient Selection for Prostate Artery Embolization.

Prostate artery embolization (PAE) has been shown to be safe and effective at treating lower urinary tract symptoms (LUTS), urinary retention, and hematuria caused by benign prostatic hyperplasia (BPH). To distinguish from other causes of these symptoms, a multidisciplinary evaluation by a urologist and interventional radiologist should include a complete history to screen for any nonprostate causes of LUTS. The International Prostate Symptom Score is a useful objective measure to quantify the patient's urinary complaints.

Current Debates Regarding Optimal Patient Evaluation and Procedural Technique for Prostatic Artery Embolization.

There are active debates surrounding patient evaluation and procedural techniques of prostate artery embolization. This review evaluates the available evidence on the value of urodynamics, the effect of prostate gland size, the benefits of pre- and intraprocedural cross-sectional imaging, the utility of a balloon-occlusion microcatheter, the differences among embolic particle sizes and types, and the merits of radial versus femoral arterial access.

Procedural complications of inferior vena cava filter retrieval, an illustrated review.

Annually, approximately 65,000 inferior vena cava (IVC) filters are placed in the United States (Ahmed et al., J Am Coll Radiol 15:1553-1557, 2018). Approximately 35% of filters are eventually retrieved (Angel et al.

Prostatic Artery Embolization Using 100-300-μm Trisacryl Gelatin Microspheres to Treat Lower Urinary Tract Symptoms Attributable to Benign Prostatic Hyperplasia: A Single-Center Outcomes Analysis with Medium-Term Follow-up.

Purpose: To report medium-term outcomes of prostatic artery embolization (PAE) using 100-300-μm trisacryl gelatin microspheres to treat lower urinary tract symptoms (LUTS) from benign prostatic hyperplasia (BPH) and to evaluate how cone-beam computed tomography-measured prostate gland volume (PGV), median lobe enlargement (MLE), age, and Charlson Comorbidity Index (CCI) affect these results.

Materials And Methods: Seventy-four consecutive patients who underwent PAE from April 2014 through August 2018 were retrospectively reviewed. Patients had International Prostate Symptom Score (IPSS) >12, Quality of Life (QoL) score >2, prostate gland volume (PGV) >40 mL, age older than 45 years, and medical therapy failure.

Development of Research Agenda in Prostate Artery Embolization: Summary of Society of Interventional Radiology Consensus Panel.

Purpose: To summarize the Society of Interventional Radiology Foundation's Research Consensus Panel development of a research agenda on prostate artery embolization (PAE).

Materials And Methods: PAE for the treatment of lower urinary tract symptoms has been shown to be safe and effective in decreasing symptoms and prostate size. Lack of randomized controlled trials (RCTs) on PAE in the United States has prevented inclusion in American Urologic Association guideline recommendations for treatment of lower urinary tract symptoms resulting from benign prostatic hyperplasia.

Case-Control Comparison of Conventional End-Hole versus Balloon-Occlusion Microcatheter Prostatic Artery Embolization for Treatment of Symptomatic Benign Prostatic Hyperplasia.

Purpose: To compare procedural metrics and clinical improvement for prostatic artery embolization (PAE) performed with a balloon-occlusion (BO) versus end-hole (EH) microcatheter in patients with benign prostatic hyperplasia.

Materials And Methods: Retrospective review was performed of 129 patients undergoing PAE with 100-300 μm Embosphere microspheres from April 2013 through August 2018. Microcatheter selection was nonrandom, based on prostatic artery anatomy.

Iatrogenic lymphocutaneous fistula secondary to right-sided pheresis catheter placement and its percutaneous treatment: a case report.

We present a case of an iatrogenic lymphocutaneous fistula secondary to placement of a tunneled, large bore (14.5 Fr) right-sided internal jugular vein for plasmapheresis to treat antibody-mediated kidney transplant rejection. While iatrogenic lymphatic leaks caused by neck and thoracic surgeries are well described in the literature, lymphatic leak or lymphocutaneous fistula resulting from image-guided placement of a central venous catheter through the right internal jugular vein has yet to be described.

Image-Guided Transvesicular Drainage of Pelvic Fluid Collections: A Safe and Effective Alternative Approach.

To evaluate the safety and efficacy of percutaneous transvesicular drainage of pathologic pelvic fluid collections, a series of 15 patients who underwent 16 transvesicular drainage catheter placements was retrospectively reviewed. All patients had collections suspicious for infection that were posterior to the bladder or superior to the bladder behind loops of bowel, and were otherwise inaccessible. All 15 collections were percutaneously accessed via the bladder with standard drainage catheters.

Idiopathic chylopericardium treated by percutaneous thoracic duct embolization after failed surgical thoracic duct ligation.

Chylopericardium rarely occurs in pediatric patients, but when it does it is most often a result of lymphatic injury during cardiothoracic surgery. Primary idiopathic chylopericardium is especially rare, with few cases in the pediatric literature. We report a 10-year-old boy who presented with primary idiopathic chylopericardium after unsuccessful initial treatment with surgical lymphatic ligation and creation of a pericardial window.
