[Clinical and hemodynamic effects of external valvuloplasty of the sapheno-femoral junction].

Selected patients with primary varicose vein disease and sapheno-femoral reflux as the only point of regurgitation in the affected lower limb and duplex evidence of mobile valve leaflets underwent external valvuloplasty of the sapheno-femoral junction. Operations were performed under local anesthesia in one day-surgery. One PTFE sleeve 0.4 mm thick, in average 1.2 cm long and able to uncircle a circumference in average of 1.7 cm was put around the terminal Long Saphenous vein valve, located in the last centimeter of this vein. If also the subterminal Long Saphenous Vein valve site, located 5 cm below is dilated a second valvuloplasty was performed. In 15 case we used intra-operatory video-angioscopy guide. This examination allowed us to exclude two patients with valve damages not duplex demonstrable. Furthermore angioscopy permitted immediate demonstration of restored valvular function. Follow-up lasted on average 48 months: two early postoperative long saphenous vein thrombosis, and two late sapheno-femoral reflux recurrences were the main complications. We never observed graft infection. AVP was reduced and RT, measured by the means of LRR, had a prolongation after surgery. Both measurements had an highly significant difference from a statistical point of view, comparing pre and postoperative values. 95% of the operated patients have stable varices reduction. Long Saphenous Vein patency was recorded in 37 cases (92.5%). On the contrary, after high ligation, the fate of the saphenous vein in 21% of case is the occlusion. Symptoms of venous insufficiency disappeared completely in 80% of cases and improved in 95% of the operated patients.(ABSTRACT TRUNCATED AT 250 WORDS)
