An attempt was made to identify the uterine scars on transvaginal ultrasound scan and to describe their locations and morphological features. Various demographic, clinical and ultrasound data were examined in order to identify factors associated with deficient scars. Deficient scars were defined as detectable myometrial thinning at the site of the Cesarean section scar.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Lower\u2010segment uterine scars were detected in 321\/324 (99.1%; 95% CI, 98.0\u2013100) women with a history of previous Cesarean section. Sixty\u2010three (19.4%; 95% CI, 15.1\u201323.8) women had evidence of deficient Cesarean scars. Using multivariate analysis, a history of multiple Cesarean sections, uterine retroflexion and the inability to visualize all Cesarean scars in women with previous multiple Cesarean sections were all shown to be significantly associated with deficient scars.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Deficient uterine scars are a frequent finding in women with a history of previous Cesarean section. The risk of scar deficiency is increased in women with a retroflexed uterus and in those who have undergone multiple Cesarean sections. Copyright \u00a9 2007 ISUOG.
