ABSTRACT

Objective To explore the clinical value of high-frequency color Doppler ultrasound in the diagnosis of isolated calf muscle vein thrombosis (ICMVT). Methods Sonographic features of 175 patients with isolated calf muscular venous thrombosis were analyzed retrospectively and outcome of anticoagulant therapy in 1, 3, and 6 months was followed up. Diagnosis was established with high-frequency color Doppler ultrasound examination. Results One hundred and seventy-ifve patients presenting with 190 calf muscle vein thrombosis were included. One hundred and iffty-eight cases with 173 calf muscle vein thrombosis were diagnosed by high-frequency color Doppler ultrasound, 7 cases of misdiagnosis, missed diagnosis in 10 cases. The accuracy rate was 91.1%(173/190). Seven cases were misdiagnosed with 1 euroifbromatosis, 1 mixed hemangioma, 5 gastrocnemius hematoma. After diagnosis of ICMVT, all patients prescribed thrombolysis and anticoagulation therapy. High-frequency color Doppler ultrasound for 1, 3, 6 months after treatments revealed partial or complete recanalization without calf deep vein thrombosis. Typical sonographic features includedcalf muscle venous lumen dilation, tortuous anechoic lumen or hypoechoic iflling, with tubular or branched shape in the longitudinal view and oval or round shape in the transversal view. Conclusion High-frequency color Doppler ultrasound is an accurate and reliable method in the diagnosis of the isolated calf muscular venous thrombosis.
