静脉畸形骨肥大综合征的影像诊断

Imaging Diagnosis of Klippel Trenaunay Syndrome

目的 探讨静脉畸形骨肥大综合征影像诊断的征象。材料与方法 2 5例静脉畸形骨肥大综合征行下肢静脉顺行造影 ,7例行下肢动脉数字减影血管造影 ,4例行磁共振检查 ,8例行彩色多普勒超声波检查。结果 2 5例静脉畸形骨肥大综合征下肢静脉顺行造影均有浅静脉曲张 ,其外侧静脉畸形占 92 % ,9例有深静脉病变占 3 6% ;7例下肢动脉数字减影血管造影有动脉小分支异常 ,其中2例有低分流量动静脉瘘 ;4例磁共振检查有骨及血管畸形、软组织肿胀 ;8例彩色多普勒超声波对深静脉病变检查的符合率为 62 .5 %。结论 影像诊断有助于加深和扩展对静脉畸形骨肥大综合征的认识 ,为临床诊断、鉴别诊断和治疗提供依据。

Objective To study the imaging features of Klippel Trenaunay syndrome.Materials and Methods Patients with Klippel Trenaunay Syndrome underwent imaging examinations, including intravenous antegrade angiography of lower limb (n=25), intra arterial DSA (n=7), MRI (n=4) and color Doppler ultrasonography (n=8).Results Superficial varicosis of lower limbs was seen on intravenous antegrade angiograms in all 25 cases, of which 92% showed lateral veins abnormalities and 9 had deep vein deformities (36%). On IADSA, abnormality of small arterial branches was seen in 7 cases, of which 2 had low shunt volume arterio venous fistula. On MRI in 4 cases, bone and soft tissue hypertrophy, and varicosis were found. The coincidental rate for deep vein abnormalities in 8 cases with color Doppler ultrasonography was 62.5%. Conclusion Imaging study is very helpful for us to further understand Klippel Trenaunay syndrome and to obtain information important for diagnosis, differential diagnosis and treatment.
