Characteristics of hemodynamic changes in 8 cases of uterine arteriovenous malformation patients

Abstract

Objective To study the value of transvaginal ultrasound in diagnosis of traumatic uterine arteriovenous malformation. Methods A retrospective analysis was conducted on 28 cases of uterine arteriovenous malformation diagnosed by ultrasound after intrauterine operation in Shanghai First Maternity and Infant Hospital, Tongji University School of Medicine from 2015 to 2018. According to the diagnosis results, they were divided into arteriovenous malformation group and residual group. Peak systolic velocity (PSV), end diastolic velocity (EDV), systolic/diastolic ratio (S/D), pulsatility index (PI) and resistive index (RI) were compared. Results Eight cases were confirmed as uterine arteriovenous malformation by pathology or digital silhouette angiography (DSA), 15 cases were abortion incomplete, and 5 cases were lost to follow-up. S/D (1.41±0.10), PI (0.33±0.05), RI (0.30±0.05) in uterine arteriovenous malformation group were significantly lower than those in residue group (1.74±0.24, 0.52±0.09, 0.41±0.08)(P<0.01). The changes of PSV and EDV were not statistically different. Conclusion The hemodynamic parameters of the focus by transvaginal ultrasound can improve the accuracy of traumatic uterine arteriovenous malformation.
