    Abstract:
    We studied the long-term results following endoscopic dissection of crural perforating veins (EDCPV) in chronic venous insufficiency. The study comprised a total of 36 patients (41 lower limbs) who had endured the intervention concerned. The term having passed from the time of the operation till the moment of assessing the obtained outcomes varied from I to 10 years. Ultrasonographic angioscanning within the zone of the previous intervention revealed 38 perforating veins on 3.1 of the postoperative lower limbs (75.6 %). Amongst the veins revealed, most frequently encountered were Cockett's perforants (the so-called Cockett II) in the typical place - the lower third along the medial surface of the crus (29 cases). In five cases, perforants were revealed in the middle third of the crus, which located in the close proximity from the edge of the tibia (Cockett III). Perforants on the posterior crural surface were revealed on four extremities. Only 22 veins on 20 lower limbs (48.8%) turned out incompetent. The median access to perform EDPCV was used in 28 cases (68.3%); within the zone of the operative intervention performed we found 24 perforating veins, with 15 of these being incompetent. After EDPCV performed from the posterior or posterior-medial approaches on 13 limbs (317%), we revealed 14 perforating veins (of these, 7 - incompetent). Despite this, the patients regarded the effect obtained as either good or satisfactory in 79% of cases. The obtained findings suggest that thorough diagnosis of perforating reflux and improvement of the technique of endoscopic dissection thereof should be required. Along with it, it is also necessary to attentively examine the problem of the true role of the low vein-venous shunt in the pathogenesis of vein chronic diseases.
