[Revascularization for the aortoiliac regions of peripheral arterial disease]

As far as the indications for revascularization in the abdominal aortoiliac region are concerned, endovascular therapy is recommended for TASC II type A and type B lesions, and surgical bypass is recommended for TASC II type C and type D lesions. As stents have been developed and used more frequently in recent years, the results for endovascular therapy have dramatically improved, and its indications are beginning to be expanded. Endovascular therapy is the first-live therapy for stenotic lesions smaller than 10 cm in length or bilateral common or external iliac artery occulusion (type A and type B lesions). For highly skilled surgeons, endovascular therapy is the first-line therapy for type C and type D lesions exclude aorta and common femoral artery lesions. Therefore, when performing endovascular therapy for type C and type D lesions, it is necessary to sufficiently evaluate not only the skill of the surgeon, patient risk and QOL, but also revascularization. Furthermore, it is imperative to consider therapeutic options when endovascular therapy ends in failure.
