obliterative endarteritis

The effects of radiation delivered at the current low dose likely prevents further tumor growth by causing obliterative endarteritis of the vessels supplying the tumor.

Atrophy of mucosa, turbinal bones and seromucinous glands tends to occur, due to obliterative endarteritis causing decreased blood supply, hence the supplying area atrophies.

Inflammatory involvement of tertiary syphilis begins at the adventitia of the aortic arch which progressively causes obliterative endarteritis of the vaso vasorum.

While the histological features of chronic radiation enteritis, characterised by obliterative endarteritis of the small vessels in the intestinal wall, submucosal oedema, and lymphatic dilatation are well documented, there is little information about the pathophysiology of diarrhoea because of chronic radiation enteritis.
