“…Some of the studies attribute the venous insufficiency mainly to the disorder of elastic components of the vein wall, while others emphasize valvular incompetence as a major factor 11–15. According to the results of our study, restoring valvular competency and function plays an important role.…”

“…Preoperative mean vena saphena magna (VSM) diameter (5.6±1.1 mm) was significantly reduced ( P <0.01) at postoperative first day (3.1±1.1 mm), first month (3.2±1.0 mm), first year (3.5±0.9 mm), third year (3.8±1.3 mm), fifth year (4.3±0.9 mm), and seventh year (4.5±1.1 mm). Joh et al7 reported a thrombosis rate of 12.9% at 5-year follow-up, while other authors report different results 11–13. In our study, eight (9.6%) patients presented with thrombosis of GSV, and one patient (1.2%) developed deep vein thrombosis.…”

ObjectiveThe aim of this study is to present our 7-year results of external valvuloplasty for isolated great saphenous vein (GSV) insufficiency.MethodsExternal valvuloplasty was applied in 83 patients with isolated GSV insufficiency. Follow-up consisted of venous color duplex scanning performed on the first postoperative day, the first postoperative month, and then annually. Valvular insufficiency, venous reflux, and venous thrombosis formation in the saphenofemoral junction were the main outcomes.ResultsA complete clinical and radiological healing was observed in 50 patients (60%). In 13 cases (15.6%), a secondary surgical treatment was performed consisting of vena saphena magna high ligation/stripping and varicose vein excisions, mainly due to severe and progressive vena saphena magna valvular insufficiency and clinical persistence of symptoms. Eight patients (9.6%) developed superficial vein thrombosis, and only one patient (1.2%) developed deep vein thrombosis. Contact was lost from 32 patients (38.5%) for different reasons.ConclusionExternal valvuloplasty is an effective surgical technique for selected cases of isolated GSV insufficiency without extensive varicose dilatations. This alternative method can be safely administered as an alternative to high ligation and conventional GSV stripping.

“…Primary venous insufficiency occurs when there is weakness of the vein wall or of the venous valve leaflets. 1–6 External banding valvuloplasty (EBV) of the vein can be used in cases of primary vein incompetence to restore valve function. EBV of the great saphenous vein (GSV) in patients with varicose veins showed satisfactory results.…”

“…This guarantees a stable circular cross-section of the vein so that a functional closure of the valve cusps can be re-achieved. Nitinol additionally exhibits improved wear resistance [7,22], due to its higher limit of elastic strain recovery. Reduced wear leads to reduced surface cracking, corrosion and fracture.…”

This study shows first in vitro tests of a nitinol based vein cuff developed for external valvuloplasty. In contrary to currently existing vein cuffs the tested model enables minimal invasive implantation and also maintains its round pre-shaped profile at body temperature (37 • C). The examination of the cuff surface structure by scanning electron microscopy, profilometry and X-ray photoelectron spectroscopy after sterilization with ethylene oxide and before cyto-compatibility testing revealed a nearly smooth surface (mean square roughness Rq 66 ± 33 nm) which was primarily composed of nickel, oxygen, titanium, carbon and silicon where nickel was the least fraction (Ni: 0.7%, Ti: 1.7%, Si: 15.8%, O: 29.5%, C: 52.3%) of the surface elements. Si and C are supposed to be contaminations caused by a final cuff polishing with silicon carbide at the end of the manufacturing process. To evaluate cyto-compatibility initial cell adherence and cell activity were assessed. The results showed good initial cell adherence of L929 fibroblast-like cells on the cuff surface already after 24 h. The results also revealed no inhibitory effects on the activity of these cells (MTS test) later on. The test setup developed to analyse functionality in a dynamic mode was shown to be suited at blood pressures up to 300 mmHg. The cuff successfully limited dilation of varicose veins (Vena saphena magna) at physiological blood pressures (<120 mmHg) and also in cases of hypertonia (300 mmHg) to the diameter determined by the cuff (4.0 mm) over the complete testing period. This indicates that the clasp based cuff closure mechanism is suited to close the cuff under variable physiological and pathological blood pressure conditions. The cuff structure only allowed minimal adaptation on the inhomogenously dilating vein profile in the both peripheral cuff modules. Both peripheral modules followed the vessel dilation in correlation to the applied pressure. At pressures within the physiological range (≤120 mmHg) the variation of the lateral arch module diameter was only marginal, whereas at 300 mmHg pressure the peripheral modules followed vein dilation up to a diameter of 5.0 to 5.5 mm. The cuff also maintained the pre-shaped round profile in the central and peripheral modules during the pressure increase and the consecutive cuff expansion. The study showed that the first nitinol based vein cuff for external valvuloplasty was processed well enough by electropolishing and sterilization to allow culturing of L929 fibroblast-like cells on the cuff surface as a test of general biocompatibility. The cuff also proved to limit dilation of varicose veins at physiological and pathological blood pressures in vitro. Further tests with primary cells from the venous wall will follow to test the specific biocompatibility before tests in vivo can be envisaged.
