# Gastric rupture caused by intragastric perforation of splenic artery aneurysm: a case report and literature review

## TL;DR

A rare case of a splenic artery aneurysm rupturing into the stomach due to gastric cancer is reported, highlighting the importance of considering unusual causes in gastric bleeding.

## Contribution

This case report presents a rare occurrence of gastric rupture caused by intragastric perforation of a splenic artery aneurysm due to gastric cancer.

## Key findings

- The patient's gastric rupture was caused by increased internal pressure from an intra-abdominal hematoma.
- Histopathology confirmed moderately differentiated tubular adenocarcinoma in the stomach, but no malignant cells at the rupture site.
- Damage control surgery followed by total gastrectomy and splenectomy successfully treated the patient.

## Abstract

The rupture of splenic artery pseudoaneurysm (SAP) is life-threatening disease, often caused by trauma and pancreatitis. SAPs often rupture into the abdominal cavity and rarely into the stomach.

A 70-year-old male with no previous medical history was transported to our emergency center with transient loss of consciousness and tarry stools. After admission, the patient become hemodynamically unstable and his upper abdomen became markedly distended. Contrast-enhanced computed tomography performed on admission showed the presence of a splenic artery aneurysm (SAP) at the bottom of a gastric ulcer. Based on the clinical picture and evidence on explorative tests, we established a preliminary diagnosis of ruptured SAP bleeding into the stomach and performed emergency laparotomy. Intraoperative findings revealed the presence of a large intra-abdominal hematoma that had ruptured into the stomach. When we performed gastrotomy at the anterior wall of the stomach from the ruptured area, we found pulsatile bleeding from the exposed SAP; therefore, the SAP was ligated from inside of the stomach, with gauze packing into the ulcer. We temporarily closed the stomach wall and performed open abdomen management, as a damage control surgery (DCS) approach. On the third day of admission, total gastrectomy and splenectomy were performed, and reconstruction surgery was performed the next day. Histopathological studies of the stomach samples indicated the presence of moderately differentiated tubular adenocarcinoma. Since no malignant cells were found at the rupture site, we concluded that the gastric rupture was caused by increased internal pressure due to the intra-abdominal hematoma.

We successfully treated a patient with intragastric rupture of the SAP that was caused by gastric cancer invasion, accompanied by gastric rupture, by performing DCS. When treating gastric bleeding, such rare causes must be considered and appropriate diagnostic and therapeutic strategies should be designed according to the cause of bleeding.
