Rare constellation of abdominal vascular injuries in blunt trauma: Left gastric artery pseudoaneurysms and dissection

INTRODUCTION: Abdominal visceral artery pseudoaneurysms and dissections in blunt trauma are uncommon, however, solitary vascular injury of the left gastric artery and development of multifocal dissections are extremely rare with only 5 reported cases in the literature. PRESENTATION OF CASE: A 79-year-old male presents two days after a motor boating incident in profound hemorrhagic shock. Subsequent CT imaging revealed moderate hemoperitoneum, two pseudoaneurysms of the left gastric artery measuring 6 mm and 9 mm, as well as attenuation of the artery in keeping with a focal dissection and intramural thrombus, and no active extravasation. After stabilization with blood product resuscitation, he was managed conservatively with administration of ASA and close monitoring. CONCLUSION: Abdominal visceral artery vascular injuries in blunt trauma can be managed safely with close monitoring, antithrombotic agent, and medical co-morbidity optimization. Instability or worsening/ persistent symptoms should be considered for endovascular treatment or surgical ligation Further research and reporting of management approaches are required.
