4 Vascular Access Proficiency in access of any vascular bed is of foremost importance Cross-over femoral artery (retrograde) Antegrade femoral artery Retrograde SFA/popliteal/pedal artery Axillary/brachial artery Radial/ulnar artery

6 Vascular Access for L.E. interventionRetrograde - Cross-over femoral artery access Most commonly used access to the lower extremity from the contralateral femoral artery Familiar, easy & convenient (‘Comfort zone’) Have limitations

7 Cross-over FA access: LimitationsAAA stent-graft

8 Cross-over FA access: LimitationsAAA stent-graft Bilateral common iliac artery stents

9 Cross-over FA access: LimitationsAAA stent-graft Bilateral common iliac artery stents Aorto-bifemoral artery bypass; Fem-femoral bypass grafts Steep iliac bifurcation Non-compliant heavily Ca+2 ileo-femoral arteries

10 Cross-over FA access: LimitationsAAA stent-graft Bilateral common iliac artery stents Aorto-bifemoral artery bypass; Fem-femoral bypass grafts Steep iliac bifurcation Non-compliant heavily Ca+2 ileo-femoral arteries  Impediments to successful cross-over

11 Cross-over FA access: LimitationsAAA stent-graft Bilateral common iliac artery stents Aorto-bifemoral artery bypass graft Steep iliac bifurcation Non-compliant heavily Ca+2 ileo-femoral arteries Needed ‘support’ to cross femoral-popliteal/tibio- peroneal lesions & CTO Limited balloon and device catheter ‘working’ length

13 Antegrade Femoral Artery AccessAntegrade access of common femoral artery with placement of sheath into the ipsilateral femoral or popliteal artery Technical consideration: Previous imaging study showing patent CFA and proximal to mid SFA segments - ‘landing’ zone Ipsilateral Femoral Artery Antegrade Approach

15 Antegrade Femoral Artery AccessTechnical considerations: Previous imaging study showing patent CFA and proximal to mid SFA segments - ‘landing’ zone ‘Difficult’ to access in obese patients – ‘difficult’ hemostasis and risk for groin complication(s) - NOT ideal for access

18 Common Femoral Artery AnatomyInguinal skin crease (non-obese male)

19 Common Femoral Artery AnatomyIdeal Needle Entry Site

20 Antegrade CFA Access: ConsiderationsApproximately 3 cm of common femoral artery (CFA) lies between inguinal ligament and femoral bifurcation – segment to access with micropuncture needle inguin

21 Antegrade Femoral Artery: Step-by-stepAccess of CFA: Too low - not enough room to access the SFA Skin entry above the inguinal ligament (top of the femoral head) Ideal Needle Entry Site inguin

22 Antegrade Femoral Artery: Step-by-stepAccess of CFA: Less acute, i.e. <45O angle, entry is usually required for smooth insertion of sheath and catheters. Ideal Needle Entry Site inguin

23 Antegrade Femoral Artery: Step-by-stepWork on the left, Image Intensifier on the right Less radiation ‘Comfortable’ - Ergonomical Access CFA using micropuncture needle Duplex ultrasound guidance Fluoro guidance - landmarks from ‘old’ angio Insert micropuncture sheath & do angio Angio: Ipsilateral O angle Ensure CFA ‘stick’ and access into SFA Right SFA

24 Antegrade FA Access: “Wire” in DFAStick ‘too-low’ in the CFA with guidewire into the deep femoral artery Options: ‘repositioning’ of wire into SFA Re-access higher in CFA Use of SFA-’redirecting’ access device CFA DFA SFA

25 Antegrade FA Access: SFA access deviceSide hole on device allows redirecting the guidewire from the lumen of the terminal hole to the lumen of the side-hole

27 Antegrade FA Access: Use of SFA access deviceReposition SFA access device with side-hole directed towards SFA CFA DFA SFA

28 Antegrade FA Access: Use of SFA access devicePull guidewire from the lumen of the terminal hole and advance through the side-hole into the lumen of the SFA Pull out access device and advance sheath over guidewire into the SFA CFA DFA SFA

33 Antegrade Femoral Artery AccessSuccessful vascular access with good hemostasis are key to a successful percutaneous endovascular intervention. Know femoral/vascular anatomy and ‘nuances’ of antegrade femoral artery access. This technique is an important armamentarium in a vascular interventionalist’s toolbox.
