摘要
目的 分析Klippel-Trenaunay综合征(KTS)患者彩色多普勒超声表现,探讨彩色多普勒超声检查对KTS的诊断价值。方法 回顾性分析我院经临床和影像学检查确诊的25例KTS患者彩色多普勒超声检查及X线顺行静脉造影(XRV)资料,并观察其肢体软组织及静脉病变情况。结果 超声检查发现肢体软组织内血管瘤10例,主要表现为皮下蜂窝状结构,内以静脉血流频谱为主;软组织肥大20例,表现为患肢皮肤及皮下脂肪增厚,内可见曲张的静脉;浅静脉曲张21例,常见于小腿外侧浅静脉迂曲扩张;深静脉畸形4例,表现为深静脉管径变细,内径明显小于同名动脉,瓦氏试验扩张不明显;永存坐骨静脉11例,表现为下肢外侧粗大的浅静脉,最终引流至股静脉或盆腔髂静脉;静脉异常行径2例,表现为患侧大隐静脉引流入对侧髂外静脉,股外侧浅静脉直接引流入股总静脉。XRV显示深静脉畸形4例,永存坐骨静脉8例。结论 彩色多普勒超声检查是有效、可靠的诊断KTS的方法。
Objective To observe and analyze the color Doppler ultrasonography manifestation of Klippel-Trenaunay syndrome(KTS).Methods The color Doppler ultrasonography images and X-ray venography(XRV)of twenty-five patients diagnosed as KTS were retrospectively analyzed.The pathological changes of the limbs and their veins were observed.Results The color Doppler ultrasonography found tissue hemangiomas in 10 cases:there were cellular structure and venous blood in the soft tissue.The soft tissue hypertrophy were found in 20 cases:the skin and subcutaneous fat were thickened,and there were varicose vein in fat tissue of legs.The superficial varicosities were found in 21 cases,especially the lateral of legs.The abnormalities of deep veins were found in 4 cases:the deep vein became thinner,the internal diameter of the deep vein was lower than the homonymous artery,and no obvious extension on the Valsalva test.The persistent sciatic veins were found in 11 cases:the persistent sciatic vein was located at the lateral of the lower extremity,and drained into the femoral vein or iliac vein of pelvis.The abnormal pathways were found in 2 cases:one was the great saphenous vein drained into the contralateral femoral vein,and the other was the femoral lateral vein drained into the common femoral vein.The XRV found abnormalities of deep vein in 4 cases and persistent sciatic vein in 8 cases.Conclusion The color Doppler ultrasonography is an efficient and reliable imaging method for diagnosis of KTS.
