PURPOSE: To explore the efficacy of treatment for early cesarean scar pregnancy (CSP) and to evaluate the characteristics of women with subsequent mixed mass formation.
METHODS: Women with CSP, who received UACE followed by evacuation, were retrospectively analyzed. Clinical/sonographic characteristics in patients with or without mixed mass formation were compared.
RESULTS: From a total of 395 cases, 105 cases had a pregnancy residual with mixed mass formation. Blood loss and subsequent salvage intervention were significantly lower in patients without mixed mass, although all women retained their uteri. It required 50 days for the mass to resolve, 40 days for β-hCG concentrations to drop back to normal, and 61 days for menses to be restored; all of which were significantly longer than the same indices in women without a mixed mass. Clinical/sonographic characteristics predicting residual mass formation were maximal diameter of gestational sac (OR = 1.05, P = 0.001, with a sensitivity and specificity of 68.6 and 80.3%, respectively), presence of a fetal heart beat (OR = 2.63, P = 0.002, with a sensitivity and specificity of 62.9 and 67.2%, respectively), remnant myometrial thickness (OR = 108.91, P = 0.001 when thickness was less than 1 mm, with a sensitivity and specificity of 42.9% and 96.6%), location of gestational sac (OR = 59.20, P = 0.01 for complete type, with a sensitivity and specificity of 99.0 and 36.9%), and Doppler signal grading (OR = 8.08, P = 0.013 for Grade III, with a sensitivity and specificity of 83.8 and 51.0%).
CONCLUSIONS: UACE followed by evacuation was effective for CSP and subsequent mixed mass formation could be predicted by some clinical/sonographic characteristics.
