Abstract
Objective:
Recurrence is common after varicose vein surgery. Neovascularization may be one cause of recurrent veins. This was a study of PTFE patch saphenoplasty to try and prevent recurrent veins.
Design and setting:
Prospective cohort study of patients treated in a vascular surgical unit.
Patients and interventions:
Fifty patients having surgery for symptomatic long saphenous varicose veins (66 legs, 51 primary and 15 recurrent veins) had a PTFE patch sutured over the saphenous opening after flush saphenofemoral ligation.
Main outcome measures:
The rate of varicose vein recurrence and neovascularization 1 year after surgery were determined using clinical examination and venous duplex imaging.
Results:
Forty patients (80%) remained pleased with the results of their surgery. Recurrent veins were visible in 14 (21%) legs: 10 were principally due to neovascularization, two to sapheno-popliteal incompetence and two to an incompetent mid-thigh perforating vein. Three other legs had neovascularization but no recurrent veins. Both recurrent veins (47% versus 14%) and neovascularization (40% versus 14%) were significantly more common in patients having surgery for recurrent veins.
Conclusions:
PTFE patching was safe but did not abolish neovascularization. Neovascularization was the principal cause of recurrent veins in this study and perseverance with investigations into other barrier methods is worthwhile.
