A delayed gastric antral vascular ectasia: A case report and literature review.

RATIONALE: Gastric antral vascular ectasia (GAVE) is a rare cause of gastrointestinal bleeding. It presents challenges in both diagnosis and treatment.

PATIENT CONCERN: We reported a female patient who was initially misdiagnosed with hemorrhage of the digestive tract. She was treated with medication for 4 months, but her hemoglobin levels still declined without blood transfusion.

DIAGNOSIS: Her diagnosis was GAVE after an endoscopic examination.

INTERVENTIONS: She was treated with an endoscopic argon plasma coagulation treatment, an endoscopic band ligation treatment, medication, and traditional Chinese medicine.

OUTCOMES: This case was followed up for 6 months and her hemoglobin levels were above 9 g/dL.

LESSONS: A combination treatment of endoscopic and medication treatment will be a good choice of GAVE. More comprehensive understanding of GAVE will be build up with the developments of new technologies and methods.
