title: Three-dimensional angiography-guided percutaneous transluminal angioplasty for distal aorta and bi-iliac chronic total occlusion.
abstract: Percutaneous recanalization of chronic total occlusions (CTOs) in peripheral arteries, especially TASC D classification including the distal aorta and both iliac arteries is still technically challenging. The conventional technique using standard guidewires and catheters guided by computed tomography and angiography can achieve a limited initial success, depending on lesion characteristics and operator's experience. A special imaging technique using 3-dimensional rotational angiography and spatio-temporal reconstruction with endoview for a better examination of the proximal stump, exact obstruction location, and distal stump direction in a stumpless lesion can be indispensable for successful intervention. We report a successful revascularization case of stumpless distal aorta and bi-iliac CTO guided by this specialized imaging technique.
