Endovascular treatment of the superficial femoral artery (SFA) is challenging in the presence of flush ostial occlusion. One of the main challenges is the availability of access sites for intervention. Contralateral retrograde femoral access followed by cross-over and antegrade intervention while commonly used, may not be feasible in cases of altered iliac anatomy (e.g. kissing iliac stents). Ipsilateral antegrade intervention using common femoral artery (CFA) access in these instances while possible is typically challenging due to inadequate working length of the CFA for interrogation of the SFA ostium, compounded by the lack of sheath stability. The "profunda anchor" technique uses a buddy wire in the profunda femoris artery (PFA) to stabilize the sheath and allow catheter manipulation for antegrade intervention at the level of the SFA ostium. The PFA is further used as a conduit for deployment of closure device to avoid interference with the treated SFA.
在股浅动脉（SFA）开口平齐闭塞的情况下，其血管内治疗具有挑战性。主要挑战之一是可供干预的入路部位。对侧逆行股动脉入路，随后进行交叉和顺行干预，虽然常用，但在髂部解剖结构改变（如髂动脉支架吻接）的情况下可能不可行。在这些情况下，使用股总动脉（CFA）入路进行同侧顺行干预虽然有可能，但通常具有挑战性，因为CFA用于探查SFA开口的工作长度不足，再加上鞘管缺乏稳定性。“股深动脉锚定”技术在股深动脉（PFA）中使用一根导丝来稳定鞘管，并允许在SFA开口水平进行导管操作以进行顺行干预。PFA还被用作部署闭合装置的管道，以避免干扰已治疗的SFA。
