Obesity is a public health epidemic in the United States, which results in significant morbidity, mortality, and cost to the healthcare system. Despite advancements in therapeutic options for the bariatric patients, the number of overweight and obese individuals continues to rise. Thus, complimentary or alternative treatments to lifestyle changes and surgery are urgently needed. Embolization of the left gastric artery, or ?bariatric arterial embolization?, has been shown to modulate body weight in animal models and early clinical studies. If successful, bariatric arterial embolization represents a potential minimally invasive approach to treat obesity offered by interventional radiologists. The purpose of the following review will be to introduce the interventional radiologist to bariatric arterial embolization by presenting its physiologic and anatomic bases, reviewing the pre-clinical and clinical data, and discussing current and future investigations.
