Bariatic Left Gastric Artery Embolization for Obesity

Bariatric left gastric artery embolization (B-LGA) is a minimally invasive procedure that is being studied as a potential treatment for obesity. The left gastric artery is a branch of the celiac artery that supplies blood to the upper portion of the stomach. By blocking this artery with embolic agents, B-LGA aims to reduce the blood supply to the stomach, leading to decreased hunger and appetite, and ultimately, weight loss.

During the procedure, a small catheter is inserted through the femoral artery in the groin and guided to the left gastric artery under X-ray guidance. Tiny embolic agents, such as microspheres, are then injected through the catheter to block the artery and reduce blood flow to the stomach.

B-LGA is still considered an experimental procedure and its safety and effectiveness are still being studied in clinical trials. Initial results have shown that B-LGA may be a safe and effective treatment for obesity, with significant weight loss and improvement in related health conditions such as diabetes and high blood pressure.

Like any medical procedure, there are potential risks and complications associated with B-LGA, such as bleeding, infection, damage to the artery or surrounding tissue, or unintended embolization of other blood vessels. The decision to undergo B-LGA should be made in consultation with a healthcare provider, taking into consideration factors such as the patient’s overall health, the severity of their obesity, and their individual treatment goals. Other weight loss interventions, such as diet and exercise, medications, and bariatric surgery, may also be considered.
