Bariatric embolisation is an interventional procedure performed with a view to inducing weight-loss in the treatment of obesity. Evidence from clinical trials suggests that the procedure is well tolerated and has a good safety profile. Early studies demonstrate a mild-moderate beneficial effect. However, further research is required to establish the efficacy of this treatment.

Procedure
Most commonly this is performed via the splenic artery and selecting the left gastro-epiploic artery where the embolic agent (commonly microspheres) may be distributed.
Complications
- gastric ulceration
- gastric perforation
- splenic infarction
Outcomes
Preliminary studies of animal models 2,3 demonstrate histopathological evidence that the procedure reduces local ghrelin production which may serve as the underlying endocrine mechanism for weight loss.
