OBJECTIVE
Incompetent perforating veins of the medial calf, i.e. those of the Cockett groups, play a major role in the developement of chronic venous insufficiency. The aim of the present study was to test the value of duplex ultrasonography (DUS) in the diagnosis of function and localisation of those veins.
METHODS
Eighty-nine legs with incompetent perforating veins of the medial calf selected for subfascial endoscopic perforator surgery (SEPS) were included in a prospective study. Preoperative DUS was used to determine the number and localisation of the perforator veins. Findings were compared with preoperative ascending phlebography and intraoperative endoscopy during SEPS.
RESULTS
Nearly equal numbers of insufficient Cockett veins at each level were detected by DUS and ascending phlebography (Cockett III: n, 76 vs. n, 76, P, 1.0; Cockett: II n=84 vs. n=82, P=0.569; Cockett I: n, 36 vs. n, 37, P=1.0; chi(2)-test). Findings were confirmed intraoperatively.
CONCLUSION
The accuracy of DUS is comparable to phlebography for the diagnosis of incompetent perforating veins of the lower leg. DUS is non-invasive and avoids the potential risks of radiologic imaging.
目的
小腿内侧功能不全的穿静脉，即科克特组的穿静脉，在慢性静脉功能不全的发展中起主要作用。本研究的目的是测试双功超声（DUS）在诊断这些静脉的功能和定位方面的价值。
方法
89条小腿内侧穿静脉功能不全并选择进行筋膜下内镜交通静脉离断术（SEPS）的腿被纳入一项前瞻性研究。术前使用DUS确定交通静脉的数量和定位。将结果与术前上行静脉造影和SEPS术中内镜检查结果进行比较。
结果
DUS和上行静脉造影在每个水平检测到的功能不全的科克特静脉数量几乎相等（科克特III：n，76对n，76，P = 1.0；科克特II：n = 84对n = 82，P = 0.569；科克特I：n，36对n，37，P = 1.0；卡方检验）。术中结果得到证实。
结论
DUS在诊断小腿功能不全的穿静脉方面的准确性与静脉造影相当。DUS是非侵入性的，避免了放射成像的潜在风险。
