Overview

Angiodysplasia can be classified in multiple ways. The most often used classifies it according to findings on endoscopy.

Classification

There are multiple systems of classification of angiodysplasia. One system of classification is based on location, size, and number of angiodysplastic lesions. ^[1] Another system uses endoscopic findings to classify angiodysplasia into: ^[2]

Type 1: Angioectasias

Type 2: Dieulafoy’s lesions

Type 3: Pulsatile red protrusion, with surrounding venous dilatation

Type 4: Other lesions not classified into any of the above categories.
