Angioscopy-assisted valvuloplasty for primary deep venous valvular insufficiency.

Primary deep venous valvular insufficiency causes reflux syndrome. Angioscopy permits the surgeon not only to ascertain that venous valves have not been destroyed but to perform external valvuloplasty under visual control with the valves under pressure. We have performed angioscopy-assisted venous valvuloplasty in three men (mean age 36 years; range 30 to 38 years) and one woman (age 58 years). All four patients had class 3 disease (SVS/ISCVS classification). Descending phlebograms showed grade 3 reflux in one patient and grade 4 reflux in three patients. In all patients angioscopy-assisted valvuloplasty of the superficial femoral vein was combined with wrapping with a segment of polytetrafluoroethylene prosthesis, stripping of incompetent superficial veins, and subfascial ligation of perforating veins. Mean follow-up was 12 months (range 6 to 17 months). In three patients ulcers healed and did not recur; in the remaining patient nearly complete healing was obtained after skin grafting. In all patients ambulatory venous blood pressure improved significantly and venous filling time returned to normal (> 15 seconds). At duplex ultrasonography and descending phlebography, no residual reflux was demonstrated. At final follow-up, all repaired valves were patent and competent. Our experience demonstrates that angioscopy-assisted venous valvuloplasty combines the accuracy of valvuloplasty by means of phlebotomy and the simplicity of external valvuloplasty and thus is preferred to either of these methods.
