Complex, long segment lesions of the superficial femoral artery (SFA) are common, occurring in 40% of patients with peripheral vascular disease. In particular, chronic total occlusions (CTOs) continue to pose a challenge in the endovascular management of SFA disease. Several conventional wire and catheter based techniques have been described including subintimal recanalization and retrograde techniques. In addition, advances in endovascular technology have led to the development of a series of new devices aimed specifically at facilitating the crossing of long segment SFA occlusions or establishing re-entry of the true lumen. Here we present an overview of the minimally invasive techniques used to recanalize CTOs of the SFA and the latest specialized devices available for both recanalization and re-entry, as well as a summary of the literature supporting their application.
股浅动脉（SFA）的复杂长节段病变很常见，在40%的外周血管疾病患者中出现。特别是，慢性完全闭塞（CTO）在SFA疾病的血管内治疗中仍然是一个挑战。已经描述了几种传统的基于导丝和导管的技术，包括内膜下再通和逆行技术。此外，血管内技术的进步导致了一系列专门用于促进长节段SFA闭塞的穿过或建立真腔再进入的新装置的开发。在这里，我们概述了用于再通SFA CTO的微创技术以及可用于再通和再进入的最新专门装置，以及支持其应用的文献综述。
