The restricted blood flow to these organs can damage them. Wegener’s can affect other organs, but this isn’t as common, and generally isn’t as serious.

Wegener’s granulomatosis also produces a type of inflammatory tissue known as a granuloma that’s found around the blood vessels. Granulomas can destroy normal tissue. There is no known cause for Wegener’s granulomatosis.

Early diagnosis and treatment of Wegener’s granulomatosis may lead to [remission]. Without treatment, Wegener’s granulomatosis can be fatal, most commonly from kidney failure.
