Subintimal angioplasty for chronic arterial occlusions

Percutaneous treatment of peripheral arterial disease has evolved greatly. The prevalence of superficial femoral artery occlusions has necessitated new devices and techniques to treat these patients percutaneously. Presently several therapies are available or under investigation. These range from stents, drug eluting stents, covered stents, cryoangioplasty, laser recanilization, blunt micro dissection, and subintimal angioplasty. This paper will discuss the indications, technique, and results of subintimal angioplasty.
