Answer

A proximal balloon or a temporary caval filter may be used to reduce the likelihood of embolization. Venography is mandatory to confirm the clearance of the thrombus. Back bleeding does not indicate clot clearance because a patent valve can block flow, or flow can be present with patent tributaries.
