The Pronto V4 extraction catheter (Vascular Solutions) was put to use following extensive distal embolisation into the popliteal artery when treating an SFA occlusion. The thrombus extended well into the AT and TPT making it very difficult to access in its entirety but this catheter proved its worth.
Using an 0.014 wire initially parked in proximal PT (then later the AT) the catheter advanced easily and rapidly into the clot burden. The procedure was being performed from a contra-lateral approach due to uncertainty of the need to treat a possible inflow EIA stenosis, but the 138cm working length rapid exchange catheter facilitated access of the distant problem area.
The supplied 30ml lockable syringe allowed thrombectomy without needing to apply continuous suction, aspirating copious amount of cholesterol thrombus. The vast majority of the thrombus being cleared over a relatively short period of time.
Other advantages would be the short time taken to start aspirating, when compared to setting up the AngioJet system.
Disadvantages would be the rather fragile nature of the catheter. It's quite easy to kink it at the entry point to the vascular sheath, probably in part due to the fact an 0.014 wire is being used but its durability would be questionable if using for a prolonged period of time.
Overall impressive and useful device being very easy and quick to use.
