Objective: To describe the case of a patient with intraperitoneal bleeding from the gastroepiploic artery by endoscopic ultrasound who was successfully treated with transcatheter arterial coil embolization.
Patient and Methods: An 87-year-old man was referred to our hospital for examination of a gallbladder tumor. Endoscopic ultrasonography was performed using an oblique-view echoendoscope. After the endoscopic ultrasound, the patient went into shock. Computed tomography revealed a huge intraperitoneal hematoma and an aneurysm in the right gastroepiploic artery that were not seen on previous computed tomography images. Thus, urgent catheter angiography was performed, which showed a pseudoaneurysm of the right gastroepiploic artery and extravasation of the contrast medium from the pseudoaneurysm.
Results: Transcatheter arterial coil embolization was subsequently performed, and the bleeding stopped. Thereafter, his hemodynamics stabilized and his general condition improved. The patient was discharged 22 days post-treatment with an uneventful course.
Conclusion: Observation-only endoscopic ultrasound without invasive procedures can cause intraperitoneal bleeding due to a ruptured splanchnic artery. Thus, endoscopic ultrasonography should be performed more carefully in elderly patients.
