With the advancement of technology in the field of medicine, minimally invasive vascular procedures are widely utilised for therapeutic effects. Embolisation is a minimally invasive approach to occlude a vessel for therapeutic benefit. However, these procedures are associated with a small percentage of complications, one of which is the migration of the embolising agent. Migration refers to the movement of the embolisation agent (mostly a coil) from the original placement site to an unwanted location. A 59-year-old male presented with complaints of abdominal pain lasting 2-3 months. A Contrast-enhanced Computed Tomography (CECT) scan of the abdomen revealed an ill-defined infiltrative lesion arising from the neck and body of the gallbladder. Curative surgery was planned in the form of an extended right hepatectomy; however, the Future Liver Remnant (FLR) calculated was not optimal (19%). The patient was therefore referred for preoperative Portal Vein Embolisation (PVE). During the procedure, there was an accidental microcoil migration to the right heart post-PVE, which was managed by minimally invasive techniques. The importance of multimodality imaging techniques used to identify the location and multidisciplinary approaches to aid management has also been highlighted.
