Abstract:
Objective To observe and analyze the MRI manifestations of Klippel-Trenaunay syndrome(KTS).Methods Thirty-one cases with diagnosed KTS underwent MRI on a 1.5 T MR system. MRI,MR venography(MRV),MR angiography(MRA)and X-ray venography(XRV)were performed.The pathological changes of the limbs and their veins were observed.Results MRI found soft tissue hemangiomas in 12 cases,soft tissue swelling of the extremities in 27 cases,superficial varicosities in 21 cases,and malformation of the veins in 27 cases.In twenty patients who underwent both MRV and XRV, superficial varicosities in 17 cases and persistent sciatic veins in 11 cases were found with both techniques. The increase of tributary veins was found in 10 cases with XRV,while found in 15 cases with MRV.The erratic venous course was found in 4 cases with MRV.The abnormalities of deep veins were found in 8 cases with MRV,while found in 7 cases with XRV.Conclusion MRI is an efficient and reliable imaging method for diagnosis of KTS.
