A 34-year-old woman presents to the emergency department with sudden-onset, severe right lower abdominal pain that began 6 hours ago. The pain is sharp, constant, and radiates to her back. She denies fever, nausea, or vomiting but reports mild bloating and a feeling of heaviness in her pelvis over the past week. She has no significant medical history but is being evaluated for an ovarian cyst noted during a routine ultrasound 3 months ago. On physical examination, the patient is in distress. Her vital signs are stable, with no fever or hypotension. Abdominal examination reveals tenderness in the right lower quadrant without rebound tenderness or guarding. A transvaginal ultrasound revealed a twisted suspensory ligament of the ovary among other findings. What important structures are contained within the suspensory ligament of the ovary?
