Lesión de Dieulafoy: presentación de un caso con una variable anatómica atípica

Dieulafoy’s lesion is a rare and potentially life-threatening cause of gastrointestinal bleeding, resulting from vascular injury due to submucosal erosion that penetrates through the mucosa. It can lead to gastrointestinal hemorrhage with severe complications. This condition accounts for 1%–2% of gastrointestinal bleeding cases, most commonly occurring in the gastric fundus, and it typically affects individuals over 50 years of age with multiple comorbidities. This report describes a rare etiology of gastrointestinal bleeding associated with a thrombectomy and an atypical anatomical location.
