|October 1, 1980
Summary
Polytetrafluoroethylene (PTFE) axillofemoral bypass grafts show promising patency rates comparable to traditional methods. These results support expanded use of PTFE grafts for peripheral artery disease, with careful attention to surgical technique.
Area of Science:
- Vascular Surgery
- Biomaterials Science
Background:
- Axillofemoral bypass grafts are an alternative to aortoiliac/femoral grafts.
- Polytetrafluoroethylene (PTFE) grafts offer theoretical advantages for improved patency.
Purpose of the Study:
- To evaluate the clinical outcomes and patency rates of PTFE axillofemoral bypass grafts.
- To determine if PTFE grafts support broadened indications for axillofemoral bypass procedures.
Main Methods:
- A clinical trial involving 29 PTFE axillofemoral bypass grafts.
- Life table analysis was used to calculate cumulative patency rates over 21 months.
Main Results:
- A 21-month cumulative patency rate of 79% for patent grafts and 84% for functioning grafts.
- Four graft failures occurred, with one successfully revised.
- Three complications involved anastomosis avulsion; no infections were reported.
Conclusions:
- Early results suggest PTFE axillofemoral grafts achieve patency rates comparable to aortoiliac/femoral grafts.
- The characteristics of PTFE appear to contribute to minimized blood loss and hematomas.
- Careful graft sizing is crucial to prevent avulsion complications.
