Chronic subdural hematoma is essentially managed by surgical intervention. In recent times, middle meningeal artery embolisation has emerged as a less invasive procedure in such cases. The use of fine catheters to selectively embolise the specific involved branches of the middle meningeal artery using polyvinyl alcohol particles looks promising; however, the presence of anastomotic arteries can result in reflux and embolisation of these atypical branches, causing a myriad of complications. There is a need to identify these abnormal vessels in time to have a positive outcome with the least complications.
