Fifty-eight legs were investigated by descending phlebography using a standard Valsalva maneuver in 38 patients with varicose veins who were suspected of having primary long saphenous vein incompetence on the basis of clinical examinations, tourniquet tests, and Doppler sonography. In 21 (36%) of 58 legs the clinical diagnosis was confirmed; in the rest, there was no evidence of long saphenous vein incompetence. Descending phlebography using a standard Valsalva maneuver is a reliable method of demonstrating long saphenous vein incompetence and should be performed before surgical treatment in all patients in whom there is clinical doubt about the presence or absence of this condition.

在临床检查,止血带检查和多普勒超声检查的基础上,使用标准的Valsalva手法通过下行静脉造影检查了38例静脉曲张患者的58条腿,这些患者被怀疑患有原发性长隐静脉功能不全。在58条腿中的21条 (36% 条) 中,证实了临床诊断; 在其余的情况下,没有证据表明长隐静脉功能不全。使用标准的Valsalva动作进行下行静脉造影是一种证明长隐静脉功能不全的可靠方法,对于所有对这种情况的存在或不存在有临床怀疑的患者,均应在手术治疗之前进行。
