Although ultrasonic Doppler technique is a mainstream method for identification and visualization of incompetent perforating veins, visualization is difficult in some patients. This report discusses the imaging protocol and advantages of four-dimensional CT using antegrade venography in the detection of incompetent perforating veins at our hospital. Four-dimensional CT was performed on four patients, and the incompetent perforating veins were visualized in all the patients. Regarding the patient for whom subfascial endoscopic perforator surgery was indicated, the presence of a thick perforating vein at the locus visualized by CT was confirmed. Four-dimensional CT using antegrade venography enables visualization of incompetent perforating veins and determination of the muscle compartments present. It is likely to be useful in detecting perforating veins that are difficult to visualize by ultrasonography, as well as for local diagnosis.
