Objectives: Controversy exists regarding the management of varicose veins at the level of the popliteal fossa. This questionnaire reviews the current practice of vascular surgeons. Methods: A postal questionnaire was sent to 440 consultant surgeon members of the Vascular Society of Great Britain and Ireland. Recipients were asked to indicate their current practice of investigation and management of small saphenous (SSV), gastrocnemius and Giacomini varicosities. Results: We have received 296 (67%) responses to the questionnaire. Duplex scanning is utilized by 275 (93%) for the initial assessment of patients. Preoperatively, 188 (64%) reuse duplex scanning to mark the saphenopopliteal junction (SPJ) site, 53 (18%) mark with handheld Doppler only and 24 (8%) do not mark the SPJ. At operation, 198 (67%) flush ligate the SPJ and 87 (29%) tie the SSV 2–3 cm from the junction. A total of 101 (34%) usually strip the SSV to various levels. In symptomatic patients, 158 (53%) ligate the SPJ when an incompetent segment of SSV with a competent SPJ exists. One hundred and sixty-nine (57%) disconnect incompetent gastrocnemius veins during SPJ surgery and 172 (58%) regularly look for the Giacomini vein. Routine follow-up after surgery is practised by 172 (58%), most commonly at six weeks. This is mostly (88%) by clinical examination, with 14 (8.1%) using duplex scanning and six (4.7%) using a nurse-run clinic for the follow-up. Conclusions: This review suggests marked variation in the management of popliteal fossa venous incompetence. There is a clear need for further research to clarify the role of ablation in the management of symptoms and skin changes. [ABSTRACT FROM AUTHOR]
