Spontaneous retroperitoneal haemorrhage secondary to anticoagulation polypharmacy.

Retroperitoneal haemorrhage (RH) is not uncommon in patients with provoking events like trauma. However, spontaneous RH (SRH) is a rare and life-threatening complication described as the development of bleeding into the retroperitoneal cavity, appearing spontaneously and without a preceding history of trauma or other predisposing illness. We are reporting a case of an elderly patient with recurrent deep vein thrombosis who had developed SRH secondary to concurrent use of multiple anticoagulation agents, resulting from poor healthcare follow-up and lack of sufficient medication reconciliation. This article highlights the significance of recognising risk factors for SRH, as well as management strategies through literature review.
