Endovascular Coil Embolization of a Ruptured Gastroduodenal Artery Aneurysm: A Case Report

Gastroduodenal artery aneurysms (GDAAs) are among the rarest forms of visceral artery aneurysms. Despite their rarity, GDAAs carry a high risk of rupture associated with significant morbidity and mortality, making early diagnosis and prompt intervention essential. Endovascular embolization has increasingly emerged as a minimally invasive alternative to open surgical repair. We present the case of a patient admitted with progressively worsening diffuse abdominal pain accompanied by one episode of black-colored vomiting. Contrast-enhanced computed tomography (CECT) revealed findings consistent with rupture of a GDAA. Due to the acute clinical presentation and risk of ongoing hemorrhage, the patient underwent emergency endovascular coil embolization. The procedure was successfully performed by selective catheterization of the gastroduodenal artery and proceeded without complications, resulting in hemodynamic stabilization and avoidance of open surgical intervention. This case highlights the importance of rapid radiologic diagnosis and demonstrates that endovascular coil embolization is a safe and effective minimally invasive treatment option for ruptured GDAA.
