Outcome of Patients with an Indeterminate Emergency Department First‐trimester Pelvic Ultrasound to Rule Out Ectopic Pregnancy

Abstract

The outcome of symptomatic first-trimester patients with indeterminate ED pelvic ultrasounds is poor, with significantly high rates of embryonic demise and ectopic pregnancy. However, those indeterminate patients with the eventual diagnosis of ectopic pregnancy have a higher rate of medical methotrexate treatment and a reduced rate of invasive surgical treatment compared with ectopic pregnancy patients diagnosed at initial ED visit.
