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.

Aspiration Therapy
Aspiration therapy is a novel, endoscopic bariatric therapy that allows patients to remove a portion of an ingested meal through a modified percutaneous gastrostomy tube, called an A-Tube. Weight loss results from both fewer calories consumed, and from modifications in lifestyle and mealtime behaviors that patients make as a result of having the device installed. The first commercially available device for aspiration therapy, the AspireAssist (Aspire Bariatrics, King of Prussia, PA), was approved by the Food and Drug Administration in 2016 for weight loss for greater than 6 months duration in patients with a body mass inde...

Rationale and Preclinical Data Supporting Bariatric Arterial Embolization
The prevalence of obesity is increasing globally, leading to significantly increased morbidity, mortality, and health care costs. However, there is a lack of effective treatment options that can treat patients with obesity less invasively than with bariatric surgery. Bariatric arterial embolization (BAE) is an image-guided, minimally invasive, percutaneous procedure that is currently being investigated in preclinical animal models and early clinical trials. If successful, BAE may represent a viable interventional approach for obesity treatment. (Source: Techniques in Vascular and Interventional Radiology)

Current and Future Endoscopic Weight Loss Solutions
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)

Percutaneous CT-Guided Cryovagotomy
There are a number of pathologic conditions in the human body that may be modified by the interruption of neural signaling, both related to pain and otherwise. Many of these treatments currently involve implantable neuromodulation or frank surgical neural ligation, representing opportunities for the implementation of percutaneous device-mediated cryoneurolysis in interventional radiology. Computed tomography-guided cryovagotomy for the management of mild to moderate obesity represents one such opportunity currently under investigation.

Practical Genetic and Biologic Therapeutic Considerations in Vascular Anomalies
Vascular anomalies are classified as either tumors or malformations based on clinical findings rendered through radiologic evaluation, physical exam, and histologic interpretation. These findings comprise the phenotype of the disorder. Recently, advances in the molecular genetics of vascular anomalies have shed light on the genotype of these disorders. These phenotype/genotype characterizations will provide a more precise classification of vascular anomalies and identify potential therapeutic targets for expanded treatment options in the future.

Interventional Management of Arteriovenous Malformations
Arteriovenous malformations (AVMs) are fast flow malformations characterized by the presence of arteriovenous shunting. These congenital lesions can be evolutive, leading to serious complications such as bleeding, skin ulceration, and cardiac failure. The interventional radiologist plays an important role in the management of these patients. He should be involved in the clinical evaluation to make the proper diagnosis, evaluate the symptoms and potential indication for endovascular treatment. This evaluation should be done in a multidisciplinary clinic with access to plastic surgeons, internal medicine and dermatologist, a...

Klippel-Trenaunay Syndrome
Klippel-Trenaunay syndrome or KTS is a complex vascular syndrome associated with overgrowth occurring as a result of somatic mutations in the PIK3CA gene. Patients are diagnosed on the basis of physical findings, sometimes with supportive imaging, of commonly a segmental anomaly with a cutaneous port-wine stain, lymphatic and venous malformations and overgrowth. The severity of the component vascular malformations and the degree of overgrowth varies from patient to patient which demands care given by a multi-professional team with regular follow-up in a specialist clinic.

Introduction
Vascular anomalies in some form or another are encountered frequently in day-to-day practice by diagnostic and interventional radiologists alike. In fact, depending on definition, they are now known to occur in at least 1-2% of the entire population. Within the younger pediatric population, the diagnosis of a vascular anomaly will usually mandate some series of medical consultations and possible intervention. A larger number of patients, however, will seek medical attention in adolescence or adulthood, either when lesions become symptomatic, or when incidentally detected by some other study.

Surgical Considerations in Vascular Malformations
Vascular malformations are generally congenital benign lesions that have multiple variations in treatment algorithms. Surgery can be used as a single modality or as an adjunct in multimodal therapy to treat these lesions. Here we discuss surgical treatment of the major vascular malformations, including lymphatic, venous, and arteriovenous malformations. We explain some of the basic principles to resection of simple and complex lesions and adjunctive therapies. These adjunct therapies include chemotherapeutic injections, embolization, and laser therapy. (Source: Techniques in Vascular and Interventional Radiology)

Percutaneous Cholecystolithotomy Using Cholecystoscopy
The morbidity and mortality of cholecystectomy can increase to 10% in high surgical risk patients. The technique for percutaneous cholecystolithotomy consists of 3 steps: (1) percutaneous cholecystostomy, (2) tract dilation and cholecystolithotomy, and (3) tract evaluation and catheter removal. Cholecystoscopy is critical in guiding the lithotripsy probe for fragmentation of large stones and is useful for locating small stone fragments not seen in cholangiography. Cholecystoscopy is also useful for assessing ambiguous lesions and in distinguishing between stone vs debris or mass. (Source: Techniques in Vascular and Interventional Radiology)
