Recanalization of aged venous thrombotic occlusions with the aid of a rheolytic system: an experimental study.
OBJECTIVE
The suitability of a rheolytic system for recanalization of aged venous thrombotic occlusions was tested in an animal experiment.


METHODS
The system consists of a flush-suction catheter and a high-pressure liquid pump. Thrombosis was experimentally induced in 13 venous segments of 10 adult goats.


RESULTS
After a mean period of 12 days, a complete thrombectomy using the flush-suction system was achieved in 12 cases. No complications such as perforation or dissection were observed.


CONCLUSIONS
This system seems to be an appropriate device for percutaneous transluminal venous thrombectomy, even in older occlusions.
