Posterior Gastric Artery Aneurysm.

Introduction: Aneurysms of small abdominal vessels are extremely rare; however, even minor aneurysmal accessory arteries can rupture, leading to potentially fatal consequences. The purpose of this paper is to report a case of coil embolisation of an aneurysmal posterior gastric artery.

Case presentation: The authors describe the case of a 66 year old female patient with an aneurysm of the posterior gastric artery. Coil embolisation was performed. The six month follow up computed tomography angiogram revealed exclusion of the aneurysm.

Discussion: The presented case is exceedingly rare. This type of aneurysm has to be kept in mind as a possible cause of bleeding, despite the limited information regarding their natural history.

Conclusion: Owing to the safety and applicability of the endovascular technique, it is nowadays probably the best treatment alternative for this type of aneurysm.
