Abstract
In a series of 175 polytetrafluoroethylene (PTFE) femoropopliteal bypasses for limb
salvage, nine thrombosed within the first month after operation and 22 thrombosed
from 1 to 23 months after operation. With reoperation (four simple thrombectomies
and five graft extensions) all nine early closures are patent 3 to 27 months (mean,
16 months) later. Four of the late thromboses did not jeopardize the limb, and viability
has persisted 4 to 14 months. Eighteen of the late thromboses placed the limb in jeopardy.
Appropriate reoperation after preoperative angiography restored graft patency for
2 to 27 months in 14 of 18 cases. Six grafts were patent more than 1 year after reoperation.
The operations performed for late thrombosis were incision and patch angioplasty for
intimal hyperplasia (25%), graft extension for distal disease (42%), and simple thrombectomy
when no cause of thrombosis was identified (33%). These findings justify an aggressive
approach with appropriate reoperations when PTFE femoropopliteal bypasses thrombose
in the early or late postoperative period. Important additional limb salvage can thereby
be obtained.
