Insights

Surgical transposition of the cephalic vein improves outcomes for patients with recurring cephalic arch stenosis (CAS) and brachiocephalic fistulae. This approach significantly enhances patency rates for subsequent angioplasty procedures.

Area of Science:

  • Vascular Surgery
  • Interventional Nephrology
  • Dialysis Access

Background:

  • Cephalic arch stenosis (CAS) frequently causes vascular access dysfunction in brachiocephalic fistulae.
  • Percutaneous balloon angioplasty for CAS has shown poor results due to restenosis and low patency rates.

Purpose of the Study:

  • To evaluate the efficacy of surgical transposition of the cephalic vein for managing recurrent CAS.
  • To compare angioplasty patency rates before and after surgical revision.

Main Methods:

  • Thirteen patients with recurrent CAS underwent cephalic vein transposition.
  • The procedure involved transecting and re-anastomosing the cephalic vein to an alternative inflow source.
  • Angioplasty was used post-surgery to manage access dysfunction.

Main Results:

  • Primary patency rates for angioplasty significantly improved post-surgery: 92% at 3 months, 69% at 6 months, and 39% at 12 months (p=0.0001).
  • Secondary patency also showed improvement compared to pre-surgical rates.
  • Pre-surgical primary patency was 23% at 3 months, decreasing to 0% at 12 months.

Conclusions:

  • Surgical transposition of the cephalic vein is a viable and effective option for patients with recurrent CAS.
  • This surgical approach enhances long-term patency rates for future angioplasty interventions.
