ACR Appropriateness Criteria® Postpartum Hemorrhage

Postpartum hemorrhage (PPH) can be categorized as primary or early if occurring in the first 24 hours after delivery, whereas late or delayed PPH occurs between 24 hours and 6 weeks. Most of the causes of PPH can be diagnosed clinically, but imaging plays an important role in the diagnosis of many causes of PPH. Pelvic ultrasound (transabdominal and transvaginal with Doppler) is the imaging modality of choice for the initial evaluation of PPH. Contrast-enhanced CT of the abdomen and pelvis and CT angiogram of the abdomen and pelvis may be appropriate to determine if active ongoing hemorrhage is present, to localize the bleeding, and to identify the source of bleeding. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.
