Ruptured left gastric artery aneurysm presenting with life-threatening intraperitoneal hemorrhage: a rare vascular emergency.

Visceral artery aneurysms are rare, with left gastric artery aneurysms representing a small proportion. Most are asymptomatic and incidentally detected, but rupture can lead to life-threatening intra-abdominal hemorrhage. We report a 50-year-old male presenting with sudden epigastric pain and hypovolemic shock. Imaging revealed a ruptured left gastric artery aneurysm with active bleeding and extensive hemoperitoneum. Emergency laparotomy with aneurysm excision and vessel ligation was performed successfully. The patient's postoperative course was uneventful, and follow-up imaging showed no residual aneurysm. This case underscores the need for early recognition and prompt surgical intervention to improve outcomes in this rare condition.
