Do you mean, an acute arterial clot in the site leg? Have you done any internet search for complications r/t Angioseal? What are the manufacturer's warnings?
Here's one article I found:

Perhaps you'll get different, more specific articles and information using different search words (I used "angioseal complications").
I have seen one acute occlusion of the femoral artery, related to Angioseal deployment technique (IMO).
My only concern about using Angioseal is increased risk of infection r/t insertion of a foreign substance. I have seen two pts return for groin problems post-cath, who were admitted and treated for cellulitis.
