Post‐delivery/‐abortion uterine artery pseudoaneurysm (UAP) sometimes causes life‐threatening bleeding, requiring transarterial embolization (TAE). It is unclear whether some UAP resolve spontaneously. In three patients, UAP resolved spontaneously without TAE. Case 1 was after vacuum delivery with slight bleeding: at day 5 post‐partum, a yin‐yang sign on Color Doppler and an enhanced intrauterine sac‐like structure were observed, leading to the diagnosis of UAP, which disappeared at 4 weeks post‐partum. Case 2 was after vacuum delivery with manual placental removal and was asymptomatic: a hypoechoic intrauterine mass with a yin‐yang sign were observed during a post‐partum routine check‐up and the intrauterine flow disappeared at 4 weeks post‐partum. Case 3 was after dilatation and curettage in the first trimester with slight bleeding: UAP was detected at 4 weeks post‐abortion, which disappeared at 6 weeks post‐abortion. All three cases had a small UAP (diameter: 10–15 mm) and low‐level or no symptoms. Some UAP may resolve spontaneously and, thus, may not require TAE.
