A 27-year-old woman presents with sudden-onset severe pelvic pain, vaginal bleeding, and hemodynamic instability (BP 92/58, HR 118). She reports amenorrhea for 6 weeks. Vital signs show tachypnea at 22 breaths/min and SpO2 98% on room air. Transvaginal ultrasound confirms ruptured ectopic pregnancy with free fluid in the pelvis. She denies prior abdominal surgery. Free intraperitoneal blood accumulating in the most dependent peritoneal recess while upright would most likely collect in which anatomical space?
- A)Vesicouterine pouch
- B)Posterior fornix
- C)Rectovesical pouch
- D)Broad ligament
- E)Rectouterine pouchGABARITO
