Coronary Chronic Total Occlusion Antegrade Wire Technique to Successfully Cross a Common Iliac Chronic Total...

Percutaneous endovascular intervention is the preferred modality of revascularization for iliac arterial obstructive disease. Chronic total occlusions (CTO) of the iliac arteries can be uniquely challenging, as typically utilized polymer jacketed 0.035 in wires have a tendency to enter subintimal planes within the iliac artery or aorta, which consequently require complicated re-entry wire techniques. We present a case of a common iliac chronic total occlusion, initially unable to be crossed with a traditional 0.035 in polymer jacketed guidewire due to subintimal entry. Instead, using an antegrade coronary CTO wire escalation technique with a 0.014 in coronary CTO guidewire, the iliac occlusion was successfully crossed via the true lumen.
