Abstract
BACKGROUND

Gastric submucosal arterial dilation resulting from splenic artery occlusion represents an exceedingly rare etiology of acute upper gastrointestinal bleeding (UGIB). Although endoscopy is a widely utilized diagnostic and therapeutic modality for gastrointestinal bleeding, it has limitations in detecting arterial abnormalities.

CASE SUMMARY

This report presents a rare case of massive UGIB in a 57-year-old male with a tortuous left inferior phrenic artery accompanied by splenic artery occlusion. “Gastric varices” was identified during the patient's endoscopy one year before hemorrhage. Despite initial hemostasis by endoscopic clipping, the patient experienced massive rebleeding after one month, requiring intervention with transcatheter arterial embolization (TAE) to achieve hemostasis.

CONCLUSION

This is the first case to report UGIB due to a tortuous left inferior phrenic artery. This case highlights the limitations of endoscopy in identifying arterial abnormalities and emphasizes the potential of TAE as a viable alternative for the management of arterial bleeding in the gastrointestinal tract.

Core Tip: Endoscopy has become a widely used diagnostic and therapeutic tool for gastrointestinal bleeding, effectively screening for gastric varices and achieving hemostasis. However, arteries can mimic varices, and their ruptures require multidisciplinary discussion and alternative therapeutic options. Gastric submucosal arterial dilation due to splenic artery occlusion constitutes an exceptionally rare cause of acute upper gastrointestinal bleeding (UGIB). This is the first documented instance of UGIB originating from the left inferior phrenic artery. The study provides valuable insights into the clinical diagnosis and management of this rare and challenging condition.
