Earlier studies using Doppler ultrasound suggested that thigh telangiectasia might be associated with reflux in the larger subcutaneous veins.
The aim of the study was an accurate description of the anatomy of the venous drainage from thigh telangiectases and evaluation of the extent of venous valvular incompetence using a noninvasive imaging method.
High-definition color duplex ultrasonography was used to achieve the objective.
Thirty-seven legs with lateral and/or medial thigh telangiectasia were examined. Patients studied were those without saphenofemoral, saphenopopliteal, or deep venous abnormalities on Doppler ultrasound examination. Altogether 53 sites were tested. In 89% reticular vein incompetence was found close to telangiectases. Often reticular vein incompetence was associated with reflux in larger epifascial veins. In 15% incompetent perforating veins were detected between reticular veins and the deep venous system.
An accurate, functional reconstruction of the subcutaneous venous drainage was accomplished. It was found that telangiectasia was rarely an isolated condition, but was usually associated with incompetence in other elements in the venous drainage of the subcutaneous tissue.
早期使用多普勒超声的研究表明,大腿毛细血管扩张可能与较大的皮下静脉反流有关。
本研究旨在准确描述大腿毛细血管扩张的静脉引流解剖结构,并使用无创成像方法评估静脉瓣膜功能不全的程度。
采用高分辨率彩色双功超声来实现这一目标。
对37条大腿外侧和/或内侧有毛细血管扩张的腿进行了检查。研究对象为多普勒超声检查无大隐静脉-股静脉、小隐静脉-腘静脉或深静脉异常的患者。共检测了53个部位。89%的患者在毛细血管扩张附近发现网状静脉功能不全。网状静脉功能不全常与较大的筋膜上静脉反流有关。15%的患者在网状静脉和深静脉系统之间检测到功能不全的穿通静脉。
完成了皮下静脉引流的准确功能重建。发现毛细血管扩张很少是孤立的情况,通常与皮下组织静脉引流中其他成分的功能不全有关。
