Abstract

Background

Segmental arterial mediolysis (SAM) is a rare non inflammatory vascular disease that can present with massive haemorrhage, which may lead to death without prompt surgical intervention.

Case presentation

A 60 years old Aboriginal female presented with life threatening, spontaneous intra-abdominal bleeding requiring an emergency laparotomy. The source of bleeding was found to be ruptured left gastric artery. A total gastrectomy was performed as a damage control procedure. A staged Roux-en-Y oesophago-jejunostomy with Hunt Lawrence pouch reconstruction was undertaken thirty six hours later. Histopathological findings revealed evidence of non-inflammatory segmental vascular damage with microaneurysm, consistent with segmental arterial mediolysis.

Conclusion

Prompt resuscitation and surgical intervention can decrease the morbidity and mortality in this rare clinical entity.
