"Aneurysm" is the term I believe you are looking for allalone.

It is a very rare and disputable as to if breath play would cuase or agravate an aneurysm but a far more likely possibility to occur than cuasation of an embolism.

Aneurysms are mentioned in the very informative article link tusayan provided.

Or both terms may be looked up online quite easily if one wishes to find a second or even third oppinion considering the lack of academic oversite exercised on the internet.
