Sounds like an agressive way to treat an injury or DVT. Is there any connection between Pierre Spies clots and David Lyons? I guess I'll have to ask a doctor.

"They put in a catheter down from the top of my groin," Lyons told Sydney's Daily Telegraph newspaper. "They never really do this on legs, they normally only do it on heart patients. No one's ever really done it on the calf before. They usually just leave it because it heals itself. But that can take up to six months. Every couple of minutes a machine squirts fluid out of the catheter right into the clot to try to break it down. The doctor has the blood flowing again so hopefully that will speed the process up."
