CHALLENGE OF CTOS

Chronic Total Occlusions (CTOs) of the arteries represent one of the most challenging problems in contemporary vascular intervention and, historically, often times were impossible to revascularize.

  • 40% of patients that are symptomatic have a CTO1.
  • 20% of cases in heavily calcified CTOs are unable to be revascularized using traditional guidewire and balloon techniques2.
  • Intraluminal recanalization of complex CTOs with standard wires and balloon catheters may be achieved in 40–60% of cases3.
  • Nearly 50% of SFA lesions present as CTOs4.
  • CTOs are the most common reason to send a patient to surgery5.
