To describe a novel technique designed to safely and precisely deploy the Supera stent accurately at the ostium of the proximal superficial femoral artery (SFA) without compromising the profunda and common femoral arteries.
After antegrade crossing of the chronic total occlusion (CTO) at the SFA ostium and accurate predilation of the entire SFA lesion, a retrograde arterial access is obtained. The Supera stent is navigated in retrograde fashion to position the first crown to be released just at the SFA ostium. Antegrade dilation is performed across the retrograde access site to obtain adequate hemostasis. The technique has been applied successfully in 21 patients (mean age 78.1±8.2 years; 13 men) with critical limb ischemia using retrograde Supera stenting from the proximal anterior tibial artery (n=6), the posterior tibial artery (n=2), retrograde stent puncture in the mid to distal SFA (n=2), the native distal SFA/proximal popliteal segment (n=6), and the distal anterior tibial artery (n=5). No complications were observed.
Distal retrograde Supera stent passage and reverse deployment allow precise and safe Supera stenting at the SFA ostium.
描述一种新的技术,旨在安全、精确地将 Supera 支架准确地部署在股浅动脉(SFA)近端口部,而不影响股深和股总动脉。
在 SFA 口部的慢性完全闭塞(CTO)顺行通过后,对整个 SFA 病变进行准确预扩张,获得逆行动脉入路。Supera 支架逆行导航,使第一个释放的支架冠位于 SFA 口部。在逆行入路处进行顺行扩张,以获得充分的止血。该技术已成功应用于 21 例(平均年龄 78.1±8.2 岁;13 名男性)有严重肢体缺血的患者,采用逆行 Supera 支架置入术,从近端胫前动脉(n=6)、胫后动脉(n=2)、中下段 SFA 的逆行支架穿刺(n=2)、原位 SFA/近端腘段(n=6)和远端胫前动脉(n=5)。未观察到并发症。
远端逆行 Supera 支架通过和反向部署允许在 SFA 口部进行精确和安全的 Supera 支架置入。
