Dieulafoy Lesion: Scope it Until You Find it.

Area of Science:

• Gastroenterology
• Vascular Medicine

Background:

• Dieulafoy lesions are a critical consideration for recurrent, unexplained gastrointestinal (GI) bleeding.
• These lesions involve aberrant submucosal vessels that fail to constrict, leading to severe arterial hemorrhage.

Observation:

• Patients often present with hemodynamic instability and require multiple blood transfusions.
• Concomitant cardiac and renal conditions increase transfusion-related injury risks.

Findings:

• The case highlights diagnostic challenges, with the Dieulafoy lesion being non-visualizable in typical locations despite esophagogastroduodenoscopy (EGD) and CT angiography.
• This underscores the difficulty in accurately diagnosing and managing Dieulafoy lesions.

Implications:

• Increased physician awareness of Dieulafoy lesions is crucial for timely diagnosis and management.
• Understanding the risks in patients with comorbidities is vital for preventing transfusion-related complications.
