Spontaneous isolated left gastric artery dissection: unusual visceral artery dissection

Toshihisa Ichiba et al. Acute Med Surg. .

Abstract

Case: A 51-year-old woman visited our emergency department complaining of acute onset of upper abdominal pain and nausea. Abdominal contrast-enhanced computed tomography showed an isolated left gastric artery dissection and pseudoaneurysm. After conservative management for 6 days, endovascular embolization was carried out for treatment of the pseudoaneurysm. Spontaneous dissection of a visceral artery rarely occurs in the case of a left gastric artery.

Outcome: Contrast-enhanced computed tomography is essential to make an accurate diagnosis and establish a therapeutic strategy.

Conclusion: We should consider the occurrence of minor visceral artery dissection if a patient has acute abdominal pain without other obvious causes.

Keywords: Contrast‐enhanced computed tomography; left gastric artery dissection; visceral artery dissection.
