This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Abdomen & Pelvis, Subject name: Anatomy
A 41-year-old woman is admitted to the obstetrics and gynecology department for a scheduled tubal ligation procedure. Two days postoperatively the patient has a high fever and shows signs of hypovolemic shock. A radiographic examination reveals a large hematoma adjacent to the external iliac artery. Which of the following vessels was most likely injured? 
Select and explain. 
A. Ovarian arteries, B. Ascending branch of uterine arteries, C. Descending branch of uterine arteries, D. Superior vesicle artery
A: Ovarian arteries
Answer: A: Ovarian arteries 
Explanation: The ovarian arteries arise from the abdominal aorta, descend retroperitoneally along the posterior abdominal wall, and cross just anterior to the external iliac vessels. The ovarian arteries are the most likely source of blood from a hematoma following a tubal ligation. The ascending and descending uterine arteries and superior and inferior vesicle arteries branch from the internal iliac arteries and are not likely to be the source of blood in this situation.
