I've heard about the existence of so called blebs in/on aneurysms. Failed to find a clear description of what they are on google and pubmed. Are the blebs filled with serous fluid? Can anyone explain what they are? Pizzaman (talk) 09:05, 12 March 2010 (UTC)

Bleb is ambiguous medical jargon for a small outpouching. In an aneurysm, the bleb will therefore be an additional small outpouching of the aneurysm, filled with the blood from within the vessel associated with the aneurysm. Someone might also say "bleb" when they aren't sure if a vessel dilation is large enough to call an aneurysm. Bleb is also used to describe air cells in the lungs (nothing to do with aneurysms) in patients with disease of the lungs that predisposed them to pneumothorax Bakerstmd (talk) 18:51, 6 March 2014 (UTC)

A bit off-topic but a true and related problem.[edit]

So, if this is beyond normal scope and I assuem it is, id love to be directed to the appropriate place. I want to read this article, and many others. But I have a mitral valve prolapse. So how can I read this article without groping at my chest repeatedly? Im being completely serious yes. Its a heart problem that feels worse when i try to find out about heart problems.

Aneurysm types[edit]

The section called "aneurysm types" is really not adding anything to the article; it's just a list of terms with no explanation. Maybe a description of how aneurysms are classified would be more appropriate, with links to wiki pages on specific types if such pages exist. The12thMan (talk) 19:52, 16 July 2011 (UTC)


No one else seems to have brought this us, but yes the odd -ysm spelling is more common now but hasn't always been. Apparently, the spellings switched between 1880 and 1940. Anyone have a source as to why?

Also, will just leave these here for those with historical interest like me

even though most people coming to the article itself probably want the most up-to-date information without any distraction from earlier and now outdated understandings. — LlywelynII 15:28, 1 June 2015 (UTC)
