Summary

Carotid artery reconstruction using expanded polytetrafluoroethylene (ePTFE) grafts is a safe and durable alternative for complex cases, showing comparable outcomes to standard carotid endarterectomy (CEA). This method offers excellent long-term patency and stroke-free survival.

Area of Science:

  • Vascular Surgery
  • Cardiovascular Research
  • Surgical Reconstruction

Background:

  • Carotid endarterectomy (CEA) techniques have advanced, but complex cases require alternative reconstruction methods.
  • Prosthetic interposition grafts offer a durable solution for challenging carotid artery reconstructions.

Purpose of the Study:

  • To evaluate the safety and efficacy of carotid replacement with expanded polytetrafluoroethylene (ePTFE) interposition grafts (REP) compared to standard CEA.
  • To assess perioperative risks, long-term patency, and stroke-free survival rates.

Main Methods:

  • Retrospective review of 482 carotid endarterectomies (1999-2003).
  • Comparison of 51 REP cases with 427 CEA cases (with or without patch closure).
  • Follow-up included duplex ultrasound, assessing patency and survival using statistical and life table analyses.

Main Results:

  • No significant difference in perioperative stroke rates between REP (1.9%) and CEA (0.70%).
  • Long-term (3-year) patency and stroke-free survival exceeded 96% in both groups.
  • REP was more frequently used in reoperative procedures.

Conclusions:

  • Carotid interposition reconstruction with ePTFE grafts is a viable alternative for technically difficult endarterectomies.
  • ePTFE graft replacement demonstrates safety, durability, and comparable intermediate-term outcomes to CEA.
