Body composition changes after left gastric artery embolization in overweight and obese individuals

Purpose To determine the effects of left gastric artery embolization (LGAE) on computed tomography (CT) body composition change. Materials and methods Sixteen overweight or obese patients who had abdominal CT scans before and after LGAE for gastric bleeding were retrospectively reviewed. Body composition analysis was performed with semiautomated imaging processing algorithms (MATLAB 13.0, Math Works, MA). Adipose tissue and lean skeletal muscle were measured using threshold attenuation values. Total body fat index (BFI), subcutaneous fat index (SFI), visceral fat index (VFI), intramuscular fat index (IMFI), and skeletal muscle index (SMI) were determined ([tissue area (cm)] 2 /[height (m)] 2 ). Excess body weight (EBW) was determined based on the Lorentz formula for ideal body weight. Results Mean follow-up was 1.5 ± 0.8 months. Following LGAE, patients experienced significantly decreased body weight ( p = 0.003), BMI ( p = 0.005), EBW ( p = 0.003), BFI ( p = 0.03), SFI ( p = 0.03), and SMI ( p
