'''Angiodysplasia''' is a benign pathology of the large bowel. | |||
==General=== | |||
*Causes (lower) GI haemorrhage. | |||
*Generally, not a problem pathologists see. | |||
*May be associated with [[aortic stenosis]]; known as ''Heyde syndrome''.<ref name=pmid19652242>{{cite journal |author=Hui YT, Lam WM, Fong NM, Yuen PK, Lam JT |title=Heyde's syndrome: diagnosis and management by the novel single-balloon enteroscopy |journal=Hong Kong Med J |volume=15 |issue=4 |pages=301–3 |year=2009 |month=August |pmid=19652242 |doi= |url=http://www.hkmj.org/abstracts/v15n4/301.htm}}</ref> | |||
Epidemiology: | |||
*Older people. | |||
Etiology: | |||
*Thought to be caused by the higher wall tension of cecum (due to larger diameter) and result from (intermittent) venous occlusion/focal dilation of vessels.<ref name=Ref_PBoD854>{{Ref PBoD|854}}</ref> | |||
==Gros=== | |||
*Cecum - classic location. | |||
Note: | |||
