Massive bleeding from gastric ulcer-induced splenic artery pseudoaneurysm successfully treated with transcatheter arterial embolization and surgery: a case report

Abstract

BackgroundUpper gastrointestinal bleeding (UGIB) is a routine medical emergency. The most common non-variceal cause is peptic ulcer disease, while a rare presentation is peptic ulcer-induced splenic artery pseudoaneurysm (SAP). Primary endoscopic treatment is generally attempted for UGIB; however, it sometimes fails when arterial etiology is present. In such cases, either transcatheter arterial embolization (TAE) or surgery is necessary, but the choice of treatment is controversial. We present a case that illustrates the utility of both approaches in a gastric ulcer-induced SAP.Case presentationA 33-year-old male presented with hemorrhagic shock secondary to UGIB. The source of bleeding was identified as an SAP that was caused by a gastric ulcer. TAE enabled temporary bleeding control despite the patient’s poor overall condition and limited blood transfusion capability. However, rebleeding occurred soon after stabilization. Ultimately, we performed proximal gastrectomy and splenic artery ligation, and the patient survived.ConclusionsSAP is an uncommon occurrence, and angiographic information is important for correctly identifying the source of bleeding. The treatment for SAP bleeding is basically the same as for endoscopically unmanageable non-variceal UGIB, since TAE and surgery each have a different utility, depending on the situation. If surgery is performed, especially SA ligation and gastrectomy, it is important to consider the circulation of the spleen and residual stomach. Using TAE and laparotomy, we managed to save the life of the patient with massive hemorrhage under limited circumstances.
