Ultrasound appearance of the area of uterine closure in asymptomatic patients at 48 hours of uneventful cesarean section

Objective. - It seeks to assess the appearance of the hysterorrhaphy area and seeks hematoma in asymptomatic patients at 48 hours of their cesarean. Method. - It is common to see, ultrasound or CT scan, collection of images next to the hysterorrhaphy area in symptomatic patients after cesarean. Their interpretation remains difficult which led us to propose a prospective study looking for an evocative image collection or hematoma in asymptomatic patients at 48 hours of their cesarean. It was directed suprapubic and transvaginal pelvic ultrasound with study area hysterorrhaphy and inter-uterine bladder space. Results. - The suprapubic ultrasound examination was performed in 31 asymptomatic patients after collecting their written consent. Twenty-eight patients also received an endovaginal examination. The studied area was easily identified by visualizing the path of hysterotomy and hyperechoic aspect of the hysterorrhaphy. In 28 cases there were no abnormal image in front of the hysterorrhaphy area. In 3 cases, an evocative image of a haematic collection was displayed and measured a maximum of only 49 mm long axis with a weak Doppler signal. The exam was very well tolerated by patients, especially by transvaginal route. Also the duration of ultrasound never exceeded 58 seconds and remained fastest vaginally. Conclusion. - This preliminary work to a prospective double cohort (symptomatic patients and asymptomatic patients) has clarified the technique to use and focus in the search for a collection next to the hysterorrhaphy area. Ultrasound examination postoperatively, especially vaginally, is very fast, well tolerated with satisfactory image quality. Finally in this cohort of asymptomatic patients, it was very unusual for a collection, confirming the credit to be given to this type of image in case of symptoms after cesarean.
