Combined retrograde-antegrade arterial recanalization through collateral vessels: redefinition of the technique for below-the-knee arteries.
The effectiveness of below-the-knee PTA to obtain successful revascularization in patients with critical limb ischemia (CLI) has been well established, and many centers have adopted endovascular intervention as the first-line treatment in patients with chronic lower-extremity disease. The well-known complex and multilevel arterial disease in patients with CLI have lead to interventionists to continuously implement different technologies and techniques. The aim of the present study was to standardize and redefine a technique characterized for combined retrograde-antegrade recanalization of a native leg artery through a collateral arterial branch by using a single access. This concept has been well described in coronary arteries and recently in pelvic and tibial arteries.
