Abstract：Objective: To study the value of color Doppler ultrasonography in diagnosing congenital aneurysm. Methods: Two-dimensional ultrasonogram and color Doppler ultrasonography were performed in 16 cases of congenital aneurysm. Three-dimentional reconstruct of the aneurysms and wide-eyesight imaging technique were performed simultaneously. Results: After the diagnosis by color Doppler ultrasonography, the diagnosis of the 16 cases is further approved by pathology and angiography. The sonograms of congenital aneurysm manifestate mainly as follow: the inside of the body is a familiar heterogeneous echoless area, or an echoless area with irregular weak or strong echo of strip or tubal form. CDFI possesses rebundant blood flow which seems to like various kinds of colors mixed together. The three-dimensional imaging technique and wide-eyesight imaging technique can reflect the stereo form, scale of the aneurysm body and its relationship with the tissue around it. Conclusions: Color Doppler ultrasonography is of important application value to the clinical diagnosis and selection of the treatment. Three-dimensional ultrasound and wide-eyesight imaging technique are good supplements to two-dimensional ultrasound.
