Figure 1b. Pseudoaneurysm after D&C in a 28-year-old woman. The patient had intermittent vaginal bleeding after a spontaneous abortion followed by D&C 7 months earlier. At presentation, the serum ß-human chorionic gonadotropin (HCG) test was negative. (a) Longitudinal gray-scale US image shows a cystic lesion (between cursors) in the left wall of the lower uterus. (b) Longitudinal color Doppler US image shows that the cystic structure is filled with blood and has varying colors (arrow). (c) Longitudinal duplex Doppler US image shows turbulent arterial flow within the sac. (d) Left internal iliac angiogram shows the pseudoaneurysm (arrows), which is supplied by the left uterine artery (arrowhead). After embolization with a 3-mm-diameter coil, the pseudoaneurysm disappeared. Follow-up US showed no evidence of the pseudoaneurysm.
