Popliteal venous reflux is not abolished by superficial venous ligation

Abstract

Introduction: The role of superficial venous surgery in the presence of deep venous reflux is not well defined. Abolition of deep reflux in the femoral segment after superficial venous surgery has been reported. The popliteal segment has not been investigated similarly.

Aims: To investigate if popliteal venous reflux can be abolished by superficial venous ligation.

Method: Retrospectively identified consecutive patients with mild category exclusive popliteal reflux were invited by post to attend for a repeat duplex scan after surgery. They had previously undergone superficial venous surgery aiming to eliminate all sites of superficial reflux identified on duplex scanning.

Results: Of the 34 patients invited, 21 attended: eight males and 13 females, mean age 60 years. Seven patients were suitable for bilateral investigation. Of the 28 segments scanned, the reflux category improved in three, deteriorated to the moderate category in six and remained unchanged in 18.

Conclusion: Superficial venous surgery does not abolish mild popliteal reflux.
