Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Endoscopic Hemostasis
Minimally invasive endoscopic technique to identify and treat bleeding jejunal arteriovenous malformations using coagulation or band ligation methods. Requires specialized enteroscopy equipment and expertise.
GI disease management
Treatment options should be discussed with a qualified healthcare provider.
Segmental Jejunal Resection
Surgical removal of the affected jejunal segment containing the arteriovenous malformation. Typically performed when endoscopic access is not feasible or with recurrent bleeding.
Additional treatment options
Angiographic Embolization
Interventional radiology technique to selectively embolize feeding vessels of the malformation, reducing bleeding risk. Less invasive alternative to surgery.
procedureIron Supplementation
Oral or intravenous iron replacement to address iron deficiency anemia resulting from chronic blood loss. Supports overall recovery and energy levels.
medicationSurveillance Enteroscopy
Regular endoscopic surveillance to monitor for recurrence or development of additional malformations. Important for patients with multiple or diffuse lesions.
