目的分析 Klippel-Trenaunay 综合征(KTS)的 MRI 影像表现,评价其在 KTS 诊断中的作用。方法对经临床和影像检查符合 KTS 诊断标准的31例 KTS 患者患肢进行 MR 常规扫描、MR血管成像(MRA)、静脉血管成像(MRV)和 X 线顺行静脉造影(XRV)检查,并观察肢体及静脉病变情况。结果 12例 MRI 发现肢体软组织内血管瘤。软组织肥大27例。浅静脉曲张21例。静脉畸形27例。20例同时行 MRV 与下肢 XRV 的患者显示浅静脉曲张和特征性坐骨神经均分别为17和11例。下肢 XRV 检查显示静脉属支增多10例;MRV 显示静脉属支增多15例和静脉行径异常4例。MRV 显示深静脉异常8例,下肢 XRV 显示深静脉异常7例。结论 MRI 是诊断 KTS 有效和可靠的影像检查方法。
Objective To analyze the MRI manifestations of Klippel-Trenaunay syndrome (KTS) and evaluate its role in the diagnosis of KTS. Methods Thirty-one patients with KTS who met KTS criteria by clinical and imaging examination were examined by conventional MRI, MR angiography (MRA), venous angiography (MRV) and X-ray venography (XRV) Limbs and venous disease. Results 12 cases of soft tissue within the MRI findings of hemangioma. Twenty-seven cases of soft tissue hypertrophy. Superficial varicose veins in 21 cases. 27 cases of venous malformations. Twenty patients who underwent both MRV and lower extremity XRV showed superficial varicose veins and characteristic sciatic nerve in 17 and 11 patients, respectively. Lower extremity XRV examination showed an increase of venous branches in 10 cases; MRV showed an increase of venous branches in 15 cases and venous abnormalities in 4 cases. MRV showed deep vein abnormalities in 8 cases, lower limb XRV showed deep vein abnormalities in 7 cases. Conclusion MRI is an effective and reliable diagnostic method for KTS.
