Recanalization of aged venous thrombotic occlusions with the aid of a rheolytic system: an experimental study
1Clinic for Thoracic and Cardiovascular Surgery, Georg-August-University Göttingen, Robert-Koch-Str. 40, D-37075 Göttingen, Germany.
Purpose:
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.
Conclusion:
This system seems to be an appropriate device for percutaneous transluminal venous thrombectomy, even in older occlusions.
