Objectives:
It is unclear whether reflux time independently correlates with severity of symptoms in patients with great saphenous vein reflux.
Methods:
Eighty patients (mean age 64+/-12.7 years, 56% female) undergoing great saphenous vein (GSV) ablation for symptomatic reflux were assessed prospectively. Fifty-seven underwent ablation with radiofrequency, 23 with cyanoacrylate adhesive. Venous clinical severity score (VCSS) was assessed at, or prior to the time of ablation. The highest reflux time in the GSV was selected.
Results:
VCSS values ranged from 2 to 20 (median 7). Mean reflux time was 5.3 s (+/-3.3). The Spearman rank correlation yielded a value of rs = -0.123, p (2-tailed) = .279, which was not significant. The patients with concomitant deep vein reflux had higher VCSS (p < .05). Analysis of patients with only superficial vein reflux (n = 45) also demonstrated a poor correlation between VCSS and reflux time (rs = -0.051, p (2-tailed) = .741).
Conclusion:
This prospective study did not demonstrate a correlation between reflux time and VCSS.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
