Interventional Cryoneurolysis: An Illustrative Approach
The application of advanced imaging guidance and the interventional radiology skill set has expanded the breadth of nerve and nerve plexus targets in the body for potential cryoneurolysis. Advancement of the basic science supporting cryoneurolysis has further solidified proceduralists ’ confidence and ability to select and manage patients clinically. As these procedures continue to evolve, a structured approach to the wide variety of indications is necessary. (Source: Techniques in Vascular and Interventional Radiology)

Introduction
Lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH) occur in 50% of men over the age of 50 years, and prevalence increases with age. Patients traditionally have been managed with a combination of medical and surgical treatments. Transurethral resection of the prostate is the gold standard for surgical treatment of BPH. Within the past decade, prostate artery embolization (PAE) has emerged as a minimally invasive alternative for the treatment of BPH, urinary retention, and hematuria of prostatic origin.

Prostatic Artery Embolization in Refractory Hematuria of Prostatic Origin
Hematuria of prostatic origin has multiple etiologies including benign prostatic hyperplasia (BPH), iatrogenic urological trauma, prostate cancer, and radiation therapy. Hematuria secondary to benign prostatic hyperplasia can occur because of the increased vascularity of the primary gland, itself, or because of the vascular re-growth following a transurethral resection of the prostate. Prostatic hematuria usually resolves with conservative measures; however, refractory hematuria of prostatic origin may require hospitalization with treatment with blood transfusions, repeated indwelling urinary catheterization, and continuou...

Bariatric Embolization: A Narrative Review of Clinical Data From Human Trials
Bariatric arterial embolization (BAE) is a novel technique that is investigated as an alternative, often supplementary, method for weight management. BAE reduces blood perfusion to the gastric fundus, and thus, reduces the production of appetite-inducing hormones. No randomized controlled trial has evaluated the efficacy of BAE to date. Available evidence from published studies include retrospective evaluations of patients undergoing left gastric artery embolization for gastrointestinal bleeding, and early prospective, single-arm clinical trials.

Obesity poses a significant health care concern in the United States, with 39.8% of adults being classified as obese. Several different methods have been introduced to combat obesity, from medical therapy to surgical options. Bariatric surgery has been demonstrated to be superior to medical therapy alone for weight loss in obese patients. Despite this information, only about 1% of eligible patients undergo bariatric surgery per year. The reason for this treatment gap is multifactorial, but patient apprehension to undergo surgery is a major driving force. (Source: Techniques in Vascular and Interventional Radiology)
