<p><strong>Objective: </strong>To describe the diagnostic process and a structured, stepwise laparoscopic excision of a noncommunicating rudimentary uterine horn containing an ongoing pregnancy with cardiac activity, demonstrating how expert transvaginal and 3-dimensional ultrasound can guide early diagnosis and safe minimally invasive surgical management.</p><p><strong>Design: </strong>Detailed case report with diagnostic imaging, stepwise operative video, and structured 5-step surgical technique.</p><p><strong>Subjects: </strong>A 31-year-old G2P1 woman with a history of a prior low-transverse cesarean delivery presented to the emergency department with suspected ectopic pregnancy. She was hemodynamically stable with no active vaginal bleeding or acute abdominal pain. Detailed history revealed asymptomatic presentation; routine first-trimester ultrasound performed for dating had raised suspicion of an ectopic pregnancy. On physical examination, the cervix was single and the os closed; bimanual examination revealed mild adnexal tenderness on the left but no peritoneal signs. TVUS performed by a radiologist with expertise in complex pelvic anomalies demonstrated a right unicornuate uterus with normal endometrial thickness and no intrauterine gestational sac. A separate, left-sided gestational sac measuring 20 mm was identified, surrounded by a thick myometrial mantle (approximately 15 mm), with no continuity to the endometrial cavity or main uterine cornu. The gestational sac contained a yolk sac and a fetal pole, with a crown-rump length consistent with approximately 7 weeks and 6 days of gestation, and demonstrated confirmed cardiac activity. Color and spectral Doppler demonstrated robust arterial flow surrounding the gestational sac, indicating a rich vascular supply to the rudimentary horn. Three-dimensional ultrasound reconstructions confirmed the uterine anatomy as unicornuate with a noncommunicating rudimentary horn. Given the early gestational age, hemodynamic stability, clear diagnostic features on expert transvaginal and 3D ultrasound (single cervix, noncommunicating sac, robust vascularity, known unicornuate anatomy), and the time-sensitive nature of the condition, same-day laparoscopic management was chosen. Preoperative magnetic resonance imaging (MRI) was not pursued because transvaginal ultrasound provided clear anatomic delineation, including characterization of the attachment between the rudimentary horn and the unicornuate uterus, assessment of vascular supply, and evaluation of surrounding pelvic anatomy for surgical planning. Medical management with methotrexate was considered inappropriate, as it was unlikely to provide definitive treatment and carried a risk of treatment prolongation and unexpected rupture. This management aligns with published case series where expert ultrasound diagnosis is confirmed intraoperatively, and MRI is reserved as an adjunct in cases of diagnostic uncertainty (1-3).</p><p><strong>Intervention: </

<p><strong>Importance: </strong>Frozen-thawed embryo transfer cycles have risen substantially. Synchronization between the embryo and endometrium is achieved via natural or artificial hormonal preparation.
