Abstract

Pseudoaneurysm of uterine artery during pregnancy is a very rare disease. It is mostly associated with uterine artery injury, usually occurring after proceeding conditions such as history of gynecologic operation and infection. However, the best treatment modality has not been established yet. Herein, we reported a case of spontaneous formation of uterine artery pseudoaneurysm during pregnancy treated by direct thrombin injection without any complication or recurrence.

Figure

• 

  Fig. 1 Color Doppler ultrasonography of the uterine lower corpus reveals a swirling flow within the anechoic mass (characteristic yin-yang pattern), compatible with uterine artery pseudoaneurysm.

• 

  Fig. 2 Pelvic magnetic resonance imaging. A. Axial T2-weighted image shows an about 45 × 28 mm sized hyperintense mass at the left lower corpus of uterus. B, C. Axial T1-weighted images show a pseudoaneurysm originating from the left uterine artery (arrows).

• 

  Fig. 3 Color Doppler ultrasound after the thrombin injection procedure reveals lack of flow in the pseudoaneurysm, suggestive of a completely thrombosed pseudoaneurysm.

• 

  Fig. 4 After 2 weeks, follow up axial T1-weighted image shows a completely thrombosed uterine artery pseudoaneurysm without any other complications.
