“…Finally, the area of the saphenofemoral junction was assessed. Valvular incompetence was evidenced by the reversal of blood flow (reflux) longer than 0.5 s [15,18]. The probe was moved along the varicose veins to visualize the perforating ones.…”

“…CMD can be evaluated using plethysmography [2,3,[17][18][19][20], and the presence and location of venous reflux can be investigated using duplex scanning [7,8,[21][22][23]. Unfortunately, there is no reliable non-invasive test for the evaluation of perforator incompetence [24,25]. The importance of deep vein obstruction in the pathophysiology of CVI is still a matter of debate [6,12].…”

The purpose of the present study was to evaluate the relationship between calf muscle pump dysfunction (CMD) and the presence and location of valvular incompetence. Deep vein obstruction might influence CMD, and so venous outflow resistance (VOR) was measured. VOR and calf muscle pump function were measured in 81 patients, 7-13 years after venographically confirmed lower-extremity deep venous thrombosis. The supine venous pump function test (SVPT) measures CMD, and the VOR measures the presence of venous outflow obstructions, both with the use of strain-gauge plethysmography. Valvular incompetence was measured using duplex scanning in 16 vein segments of one leg. Venous reflux was measured in proximal veins using the Valsalva manoeuvre, and in the distal veins by distal manual compression with sudden release. Abnormal proximal venous reflux was defined as a reflux time of more than 1 s, and abnormal distal venous reflux as a reflux time of more than 0.5 s. No statistically significant relationship was found between the SVPT and either the location or the number of vein segments with reflux. Of the 81 patients, only nine still had an abnormally high VOR, and this VOR showed no relationship with the SVPT. In conclusion, venous reflux has a limited effect on CMD, as measured by the SVPT. The presence of a venous outflow obstruction did not significantly influence the SVPT. Duplex scanning and the SVPT are independent complementary tests for evaluating chronic venous insufficiency.

“…IPV can be detected with continuous wave (CW) Doppler, but CW Doppler has no advantage over clinical examination 81 . Compared with Duplex, CW Doppler has a low sensitivity (29%) and low specificity (15%) in detecting IPVs 27 . Nowadays, CW Doppler is not considered a reliable method to diagnose IPV 27,78,81,82 …”

“…Reflux must be measured preferably in the relaxation phase after distal compression 14 . The duration of reflux as a criterion of incompetence varies from 0.3 seconds 24 to 1 second, 25 but most authors consider reflux of more than 0.5 second as evidence for incompetence 23,26–29 . Concerning the diameter, it has been shown that IPVs have a bigger diameter than competent ones 15,23,26 .…”

Venae Perforantes: A Clinical Review

Background. Although many articles on perforating veins have been published, much knowledge about these veins is lacking. Objective. In this review relevant facts about the clinical importance of perforating veins in venous disease are described. Methods. A literature search on English, French and German articles has been performed using literature databases like Medline, Embase and Cochrane. Results. Selection criteria are described. Conclusion. A few conclusions are drawn: incompetent perforating veins can be of haemodynamic importance, especially in venous ulceration and (recurrent) varicose veins. The current definition of incompetent perforating veins is reflux more than 0,5 seconds (detected by Duplex ultra‐sonography). Good anatomical and clinical classifications are published and should be integrated in the CEAP classification. Based on the clinical classification treatment options are described for the different types of incompetent perforating veins. Two different treatment modalities for incompetent perforating veins are surgery (SEPS) and sclerotherapy. SEPS seems to be of benefit in patients with venous ulceration and advanced CVI. Sclero‐therapy (especially ultra sound guided sclerotherapy) is promising and worth further evaluation.
