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
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.
