Abstract

Purpose: We aimed to assess hemodynamic changes in calf perforator veins (PVs) after endovenous laser ablation (EVLA) of saphenous veins.

Methods: The series comprised 60 limbs of 41 patients (27 female, 14 male; median age, 43 years [range, 22-78 years]) who underwent EVLA for varicose veins. All patients were prospectively evaluated by means of color Doppler ultrasonography before and after the procedure.

Results: EVLA did not change the rate of incompetent PVs (preoperatively, 154/483 [32%] vs. postoperatively, 167/501 [33%]; P = 0.173), but significantly increased the total number of all PVs (n=483 vs. n=501, P = 0.036). Following EVLA, 28% of the limbs had thrombosis of PVs, 34% had new US-detectable PVs, 42% showed new competency, and 52% showed new incompetency. New competent PVs were found more commonly in the medial leg (ablation site) than the lateral leg (nonablation site) (28.3% vs. 11.7%, P = 0.016), while new incompetent PVs were found more commonly in nonablation site than ablation site (31.7% vs. 18.3%, P = 0.086). Additionally, new competent PVs in the posterior leg were found more often in patients who had small saphenous vein ablation than patients who did not (30% vs. 0%, P = 0.002).

Conclusion: EVLA induces numerous changes in calf PVs. These changes seem to result from flow offloading in ablation site and onloading in nonablation site in the early postablation period.
