Clot can form locally in an artery and block it (thrombosis), or clot can form elsewhere in the body and be carried in the bloodstream until it lodges in a distant artery (embolism). The blockage by the clot prevents normal blood flow to the organ served by the artery, which can result in ischemia (tissue starvation) or necrosis (tissue death)

Bleeding, infection, damage to the artery wall (rupture or dissection). Clot or plaque can break off during the intervention and pass down toward the foot, limiting flow (distal embolization). In most cases, these complications can be recognized and treated during the procedure. Rarely, open surgery or even amputation may be required.

Doppler ultrasound and clinic visit is typically performed several weeks after the procedure to confirm that the artery remains open and that symptoms have improved. Continued follow-up depends on the individual case.
