Clinical outcomes and changes in venous hemodynamics after subfascial endoscopic perforating vein surgery.
BACKGROUND
We evaluated the clinical results of subfascial endoscopic perforating vein surgery (SEPS) in patients with severe chronic venous insufficiency (CVI) (clinical class 4-6) and assessed the hemodynamic changes associated with SEPS using air plethysmography (APG).


METHODS
Forty-five patients with severe CVI who had undergone SEPS were evaluated. Clinical score and venous hemodynamics, as measured by APG before operation and at 1 month and 1 year after operation, were compared using the Wilcoxon signed rank test. Patient satisfaction (on a visual analogue scale of 0 to 100%) was also assessed.


RESULTS
There were 29 men and 16 women; their mean age was 60 years (range, 37-83). Thirty-five patients (78%) had active venous ulcers; the ulcers' mean size was 7.8 +/- 11.9 cm2 and the mean duration of ulceration was 9 +/- 10 months. There were no hospital deaths. Postoperative complications were uncommon (one groin wound infection and one case of thrombophlebitis). At a mean follow-up of 15 +/- 9 months, 34 ulcers (97%) had healed. The cumulative ulcer healing was 82% at 3 months. There were five recurrent ulcers (15%). Significant improvement was seen in the clinical scores (10 +/- 3 before operation, 6 +/- 4 at 1 month, and 4 +/- 3 at 1 year after operation). The venous filling index was also significantly improved after operation; this improvement was maintained at 1-year follow-up (7.36 +/- 6.23 ml/sec before operation, 3.63 +/- 3.90 ml/sec at 1 month, and 3.14 +/- 2.06 ml/sec at 1 year). The degree of patient satisfaction was also remarkable, with 74 +/- 17% and 90 +/- 12% satisfaction at 1-month and 1-year follow-up, respectively.


CONCLUSIONS
SEPS is a safe and effective treatment for patients with severe CVI. It leads to hemodynamic improvement, with rapid ulcer healing, and it is associated with a high degree of patient satisfaction.
