Effect of external valvuloplasty of the deep vein in the treatment of chronic venous insufficiency of the lower extremity

OBJECTIVE: This study was conducted to verify the efficacy of external valvuloplasty of the femoral vein in the treatment of primary chronic venous insufficiency (PCVI). METHODS: Forty patients with PCVI of the bilateral lower extremities were enrolled at the time of surgical management. All 80 limbs were classified as CEAP C2 to C4, with moderate incompetence of the deep vein. The limbs of each patient were randomized into one of two groups according to the operative method, so that when one limb was randomized to group A, regardless of whether it was the right or left limb, the other limb was assigned to group B. In group A, external valvuloplasty of the femoral vein was combined with surgery of the superficial venous system; in group B, surgery of the superficial venous system alone was performed. The therapeutic effects between the limbs in groups A and B were compared by color duplex scanning, a color Doppler velocity profile, air plethysmography (APG), and a CEAP severity score at 1 month, 1 year, and 3 years postoperatively. RESULTS: Within each group of limbs, no significant differences were found in the average operative time within each group of limbs. The varicose veins resolved, there were no deep vein thromboses, and the wounds healed well postoperatively in all cases. Leg heaviness was relieved completely in 90% of group A limbs (36/40) and 55% of group B limbs (22/40). Venous valve competence was achieved in 100%, 98.1%, and 90.9% of group A limbs at 1 month, 1 year, and 3 years postoperatively, respectively. The amount of venous reflux, APG indices, and CEAP severity scores were not significantly different between the two groups preoperatively (P > .05). The amount of venous reflux, reflux indices, CEAP severity scores, and muscle pumping indices improved markedly in group A limbs postoperatively compared with group B limbs (P < .01); muscle pumping indices did not improve significantly in group B limbs postoperatively (P > .05). There were significant differences in the amount of venous reflux, reflux indices, and CEAP severity scores between group A and B limbs at 1 month and 1 year postoperatively (P < .01). There were significant differences in all parameters assessed between group A and B limbs 3 years postoperatively (P < .05). CONCLUSIONS: External valvuloplasty of the femoral vein combined with surgical repair of the superficial venous system improved the hemodynamic status of the lower limbs, restored valvular function more effectively, and achieved better outcomes than surgical repair of the superficial venous system alone.

Results of Valvuloplasty in Patients Presenting Deep Venous Insufficiency and Recurring Ulceration

The purpose of this retrospective study was to assess mid-term results of valvuloplasty in patients presenting chronic recurring venous stasis ulceration. From 1988 to 1993, valvuloplasty was performed in the superficial femoral vein of 33 lower extremities in 28 patients presenting recurring ulceration. In 23 cases, previous surgery in the superficial venous system or perforating vein had failed. Preoperative work-up demonstrated primary deep venous insufficiency (PDVI) in 22 extremities (group I), proximal PDVI in association with distal postthrombotic syndrome (PTS) in 10 (group II), and Klippel-Trenaunay syndrome in 1. Hemodynamic assessment with tourniquet placement demonstrated a mean venous return time of 9 sec (+10, -8). Descending femoral phlebography showed Kistner grade 4 in 30 cases. Outcome was evaluated by clinical examination and Dupplex scan with photophlethysmography at follow-up times ranging from 2 to 7.6 years (mean: 51 months). Correlation between outcome of valvuloplasty and clinical findings was excellent. The incidence of poor clinical and hemodynamic results was higher for patients with PTS. Valve repair in association with surgery for superficial vein insufficiency and ligation of perforators gives good results in patients with isolated PDVI.     

Air plethysmographic assessment of external valvuloplasty in patients with valvular incompetence of the saphenous and deep veins

PURPOSE: The indications for deep venous valvuloplasty remain controversial in patients with incompetent deep vein valves associated with primary varicose veins. The purpose of this study was to evaluate the usefulness of external femoral valvuloplasty performed simultaneously with varicose vein surgery from the standpoint of venous function determined with air plethysmography. PATIENTS AND METHODS: Thirty-one limbs of 25 patients (12 men, 13 women; mean age, 56.3 years; range, 33 to 80 years) with chronic venous insufficiency caused by valvular incompetence of both deep veins and saphenous veins were studied in a prospective, nonrandomized fashion. Descending phlebography showed moderate to severe reflux of grade 3 or 4 with Herman and Kistner classifications. Clinical severity of disease was CEAP classification 2S (in six limbs), classification 3 (in three limbs), classification 4 (in 16 limbs), classification 5 (in two limbs), and classification 6 (in four limbs). We performed superficial venous surgery alone in 14 limbs (control group), which consisted of stripping or ligation of incompetent saphenous veins and ligation of all incompetent perforators. In the remaining 17 limbs (study group), we performed superficial venous surgery simultaneously with external valvuloplasty of the femoral vein with intraoperative endoscopic observation. Venous reflux of the limbs was evaluated with air plethysmographic examination before surgery and at 1, 6, 12, and 24 months after surgery in both groups. RESULTS: Preoperative venous filling index (mean +/- standard deviation) in the control and study groups was 9.4 +/- 3.8 mL/min and 8.8 +/- 3.5 mL/min, respectively (not significant), and it decreased to 7.0 +/- 3.6 mL/min (P <.01) and 2.8 +/- 1.0 mL/min (P <.01), respectively, 1 month after surgery. Postoperative index values in the study group were significantly lower than values in the control group (P <.01), and this difference continued for more than 2 years after surgery (P <.05). After a follow-up period of 12 to 37 months (average, 25 months), the venous clinical severity score was higher in the control group (3.4 +/- 1.7) than in the study group (2.1 +/- 0.3; P <.05), and the venous disability score was higher in the control group (1.4 +/- 0.6) than in the study group (0.8 +/- 0.8; P <.05). CONCLUSION: Although further follow-up study is necessary, these results point to the functional and clinical usefulness of femoral valvuloplasty performed simultaneously with varicose vein surgery in patients with moderate to severe deep venous reflux. The venous filling index obtained with air plethysmography is an excellent predictor of the clinical severity of the disease and of postoperative clinical results.

Does surgical correction of the superficial femoral vein valve change the course of varicose disease?

PURPOSE: We tested the hypothesis that the course of primary chronic venous insufficiency can be changed by correction of the incompetent valve in the superficial femoral vein. METHODS: This was a prospective, randomized, controlled study. A total of 125 extremities with reflux in greater saphenous and superficial femoral veins and belonging to clinical classes C2-C4 were analyzed. During the first 5 years, the type of clinical dynamics and changes in valvular function were determined in each patient. Patients were stratified according to the type of clinical dynamics and randomly assigned to treatment groups. Phlebectomy was performed in all extremities. In each of 64 extremities (the study group), the proximal incompetent superficial femoral vein valve was corrected as a part of the primary intervention. Patients were followed up for 7 to 8 years after surgery. RESULTS: The clinical dynamics of the extremity significantly depended on reflux changes. Increase in superficial femoral vein reflux was found in 74% of the extremities with progressive clinical dynamics but in only 47% of extremities with stable clinical dynamics (chi(2) = 9.71; P <.01). After surgical treatment, 65% of the extremities in the control group showed stable improvement; in 11%, recurrent varicosity was found; in 24%, the disease was aggravated. Of the extremities in the study group, 86% had stable improvement, 5% had recurrent varicosity, and 10% were aggravated (P <.05). Extremities with the progressive type of clinical dynamics were main contributors to this difference (chi(2) = 7.86; P <.05). In 92% of the extremities with corrected valves and in 50% of the extremities with increase in reflux after valvuloplasty, clinical improvement was observed (chi(2) = 11.5; P <.01). Extremities with corrected valvular function demonstrated superior results in comparison with extremities with stable valvular function in the control group (clinical improvement in 92% and 66% of extremities, respectively; P <.005). CONCLUSIONS: In patients with chronic venous insufficiency, two types of clinical dynamics, stable and progressive, can be identified. The progressive type is associated with the presence of superficial femoral vein reflux and increasing greater saphenous vein reflux. Superficial vein surgery neither corrects superficial femoral vein reflux nor prevents it from progressing further. Correction of a single superficial femoral vein valve during primary intervention significantly improves the long-term results of superficial venous surgery. This improvement is associated with the prevention of reflux progression. Surgical correction of the incompetent superficial femoral vein valve changes the course of primary chronic venous insufficiency.
