Backgroud <p>Ectopic pregnancy occurring at the stump of the fallopian tube is a rare clinical event. Early and accurate diagnosis, along with appropriate management strategies, can effectively prevent adverse outcomes in affected patients.</p> Case presentation <p>We report a clinical case of tubal stump pregnancy in a 24-year-old female, which occurred three years following salpingectomy performed due to a previous ectopic pregnancy.The patient complained of amenorrhea for 45 days, minor vaginal bleeding for 3 days, and no positive signs on physical examination. Her blood β-hCG level was 50.32 mIU/ml on April 16, 934.46 mIU/ml on April 27, and 4452.00 mIU/ml on April 29. Transvaginal ultrasound (TVUS) showed a widening of the transverse diameter of the uterus with two endometrial echoes and a medium echogenic septum in the center. There was a 0.9 × 0.9&#xa0;cm thick wall cyst like echo in the right near the uterine angle, and the echo of yolk sac could be seen inside. There was no germ or primitive heart tube beating in the cyst. Blood test results were within normal limits. Laparoscopic surgery combined with hysteroscopy was performed on the same day. Histological examination confirmed the presence of trophoblastic tissue, thereby establishing the diagnosis of ectopic pregnancy. The serum β-hCG level continued to decrease and returned to normal level at one month after operation.</p> Conclusion <p>A longer remnant of the fallopian tube may elevate the risk of tubal stump pregnancy. Therefore, the length of the fallopian tube should be minimized during salpingectomy. Patients with high risk factors of fallopian tube stump pregnancy should be highly vigilant, combined with vaginal ultrasound to determine the location of the gestational sac, to facilitate the development of an appropriate treatment strategy.</p>
