Summary

There are two ways of approaching atherosclerotic chronic occlusive femoro-popliteal arterial lesion with guide wire. One is the intraluminal approach of passing guide wire through the atheroma, the other is the subintimal approach of passing wire through the subintima of the vessel.

Either of these two interventional technique can be chosen depending on the character of the lesions they have their own pros and cons which affects the success of the intervention. The study is limited to retrospective studies to which interventional technique is better for post-procedural recurrence rate, however there is no prospective randomized controlled study.

Interventions

PROCEDURE

Intentional intraluminal approach

Interventionist performs intentional intraluminal approach to angioplasty. Dedicated 018 and 014 guidewire for Chronic Total Occlusion (CTO) lesion and Chronic Total Occlusion (CTO) devices such as Truepath or Frontrunner can be chosen by interventionist. Methods to confirm successful intraluminal wiring will be selected, as follows; 1) examination for guidewire position in different two angles on fluoroscopy or 2) intravascular ultrasound (IVUS) exam after predilation is performed with an appropriately sized angioplasty balloon. After the guidewire is passed through the lumen of target lesion, predilation of the target lesion with an optimally sized balloon will be performed prior to stent implantation. Provisional stenting should be performed, if the case that optimal ballooning response is not obtained.

PROCEDURE

Intentional subintimal approach

Interventionist performs Intentional subintimal approach to angioplasty. 035 Terumo guidewires will be used. If 035 Terumo guidewire is not able to re-entry, Re-entry devices such as Offroad or OUTBACK catheter can be used. After the guidewire is passed through the subintimal layer of target lesion, predilation of the target lesion with an optimally sized balloon will be performed prior to stent implantation. Provisional stenting should be performed; the case that optimal ballooning response is not obtained should be enrolled. The sub-optimal balloon response is defined as a residual pressure gradient of \>15 mmHg, residual stenosis of \>30%, and flow-limiting dissection.
