Proximal deep venous thrombosis following PTA of the superficial femoral artery--an obligation to disclose a complication that is rarely taken into account.

We report two cases of femoral vein thrombosis after arterial PTA and subsequent pressure stasis. We discuss the legal consequences of these complications for information policies. Because venous thrombembolism following an arterial PTA might cause serious sequel or life threatening complications, there is a clear obligation for explicit information of the patients about this rare complication.
