Abstract

Objective: To investigate the ultrasound characteristics and improve the ultrasound diagnosis of gossypiboma of the uterine isthmus caused by uncomplete absorption of the gauze after applying absorbable hemostatic gauze in cesarean section. Methods: From July 2011 to July 2016, 55 patients with masses in front of the lower segment of the uterus by ultrasound as well as results of gossypibomas by histopathology were enrolled in the study, whose sonographic features were reviewed retrospectively. Results: Sonography showed the lesion in the adjacent front of the anterior wall of the uterus in 55 patients. Forty(72.7%) masses appeared low echo, 15(27.3%) masses appeared mixed echo. Fifty(90.9%) appeared with threadlike or small patchy echogenic area. Color Doppler flow image showed no obvious blood flow in 50 cases(90.9%), but with minimal blood flow on the peripheral of the mass in 5 cases(9.1%). Conclusions: Gossypiboma related to absorbable hemostatic gauze after cesarean section may appear low or mixed echo by ultrasound. Threadlike echogenic area is typical ultrasonic feature. The radiologist may be alerted to the correct diagnosis combining with the surgical records.
