This didactic procedure regards a 60 years old man presenting a severe left lower limb claudication with rest pain (stage 3). The patient has a history of two femoro-infrapopliteal venous bypasses which both occluded shortly after. Multimodality imaging revealed a long occlusion of the femoropopliteal axis with a severely diseased posterior tibial artery. A previous antegrade attempt of recanalization failed due to severe calcification. No retrograde attempt was done due to severe claudication. The patient has finally undergone a percutaneous femoropopliteal bypass.

 

Educational objectives

  • Define the indication of percutaneous femoro-popliteal bypass (PFPB) in severe lower limb disease.
  • Plan a step-by-step procedure of PFBP.
  • How to manage antegrade and retrograde access?
  • How to choose the accurate spots for the implantation of PFPB: proximal and distal implantation.
  • Selecting the appropriate devices : guidewires, microcatheters, guiding catheter, balloons and covered stents
  • How to modify a guiding catheter for a coaxial transseptal needle system?
  • How to safely perform a puncture using transseptal needle through occluded femoral artery.
  • How to safely perform an externalization and extra-vessel trajectory?
  • Tips and tricks to a successful puncture and reentry.
  • What are adjunctive pharmacotherapies?

 

Step-by-step procedure: supra-articular femoropopliteal percutaneous bypass

1) Access sites:

  • Antegrade femoral access: 6 French sheath and 8 French sheath for final stenting.
  • Retrograde access through the anterior tibial artery (ATA).

2) Retrograde recanalization:

  • V-18™ wire and Terumo 0.035” angled stiff Glidewire® with the support of TrailBlazer™ microcatheter.
  • Advancement of knuckled wire through tibioperoneal trunk (TPT) subintimally until the landing zone (distal third of left superficial femoral artery (FSA))
  • Pre-dilatation: OTW Armada balloons : 3*60 mm then 5*60 mm.

3) Preparation of the landing zone:

  • Predilatation: OTW Armada balloon 5*60 mm.
  • Use the balloon in place to identify the landing zone..

4) Preparation of the transseptal needle:

  • 6 French guiding catheter cut to obtain a shorter one at the level of the transseptal needle curve
  • Insertion of the transseptal needle in the modified 6 French guiding catheter to protect the needle (avoid vessel perforation or dissection).
  • Coaxial system: direct the transseptal needle and puncture safely.

5) Externalisation and extravessel trajectory :

  • Puncture of the vessel wall toward the medial side of the proximal cap of the occluded vessel (avoid collateral vessels).
  • Injection of diluted Lidocaïne (0.1%) locally.
  • Advancement of the knuckled Terumo 0.035’’ angled Glidewire® into the extravascular space, paralleled to the native vessel (following calcifications) with the support of the guiding catheter.

6) Reentry

  • Balloon dilatation from retrograde access at the reentry site (REVERSE CART technique).
  • Puncture at the reentry site: balloon and guidewire from retrograde access serve as a benchmark, and orthogonal views.
  • Pre-dilatation of the reentry site: Armada OTW balloon 4*60 mm
  • Positioning of the guiding catheter downstream to the reentry site, inside the vessel structure.

7) Stenting:

  • Exchange to a support guidewire: Lunderquist Extra Stiff 0.035’’ guidewire.
  • Exchange to an 8 French sheath 45cm which is advanced downstream to the distal reentry point.
  • Stenting the reentry point: Covera™ stent 6*100 mm.
  • Stenting the extra-vessel trajectory: Viabahn®7*150 mm with long overlapping.
  • Stenting the exit point Viabahn® 7*80 mm with long overlapping.

8) Antegrade angioplasty:

  • Predilatation and stenting of the popliteal artery.
  • Remove ATA sheath and balloon hemostasis.

9) Post dilatation of the covered stents

10) Medical adjunctive treatments

  • Pre-procedural: Heparin and Antibioprophylaxis.
  • Post procedural: Triple therapy: Aspirin 75mg o.d. + Clopidogrel 75mg o.d. + Enoxaparin 100 UI/kg b.i.d. : 15 days.
  • DUS 15 days after.
  • Stop Clopidogrel and continue Aspirin 75mg b.i.d and NAOC.
