A pseudoaneurysm, also known as false aneurysm, is a collection of blood in perivascular soft tissue. Iatrogenic cause such as arterial catheterization and abdominopelvic surgery is one of the most common etiologies of pseudoaneurysm formation. Pseudoaneurysm in pelvic vessels is a complication of pelvic surgery or vessel catheterization. Cesarean section is the most common reported cause. In this article we introduced a 25 years old woman presented with abdominal pain and vaginal bleeding 1 week after Cesarean section. Imaging modalities confirmed the diagnosis of left uterine artery pseudoanurysm. Patient was admitted to treat by endovascular intervention. Several hours after admission blood pressure decreased and abdominal pain became more sever, ultra sound study showed evidence of free fluid in abdominopelvic cavity suggestive of pseudoaneurysm rupture. Emergence laparotomy surgery and hysterectomy were done due to active bleeding secondary to pseudoaneurysm rupture. Patient was discharged from hospital 5 days after surgery without any new complication.
