Chronic total occlusions in peripheral vasculature: techniques and devices.

摘要: Peripheral artery disease continues to increase in an ever-aging society and consumes a significant part of health resources. Chronic total occlusions account for portion the lesions encountered by endovascular interventionalists. Unlike coronary circulation, these are often long associated with other features complexity. The two primary issues concerning ability safely achieve intimal angiographic success long-term durability therapy. Traditionally, use percutaneous techniques was limited certain anatomic subsets, such as stenosis or occlusions. However, recent advances wire technology, re-entry catheters, alternative crossing tools atherectomy devices have increased interventional armamentarium this challenging subset. This article will focus on some chronic lesions, well available improve patency.
