What is esophageal venous aneurysm?

Esophageal venous aneurysm is caused by congenital vascular dysplasia, vasculitis, vascular injury and other reasons in most cases.

1. Congenital vascular dysplasia

patients with congenital esophageal venous plexus occlusion or stenosis, can cause abnormal expansion of the esophageal vein, thus causing esophageal venous aneurysm formation.

2. Vasculitis

patients with esophageal venous inflammatory lesions, inflammatory factors can stimulate the esophageal vein, causing congestion and edema of the esophageal vein, at this time will also form esophageal venous aneurysm.

3. Vascular injury

patients with esophageal mucosal venous plexus damage, damage site can form scars, resulting in local vascular lumen stenosis, and then lead to patients with esophageal venous aneurysm.
