Answer

Treatment of either thrombi or emboli in the setting of peripheral vascular disease is similar. Empirically, initiate a heparin infusion with the goal of increasing activated partial thromboplastin time to 1.5 times normal levels. Acute leg pain correlated with a cool distal extremity, diminished or absent distal pulses, and an ankle blood pressure less than 50 mm Hg should prompt consideration of emergent surgical referral.

In some cases of emboli, intra-arterial thrombolytic agents may be useful. The exact technique of administration varies, in both dosage and time of administration. Remember that intra-arterial thrombolysis remains investigational. Obviously, such thrombolytic therapy is contraindicated in the presence of active internal bleeding, intracranial bleeding, or bleeding at noncompressible sites.
