OBJECTIVE:To compare clinical efficacy and safety of intravenous dripping of methotrexate and uterine arterial perfusion embolization combined with complete curettage of uterine cavity (CCUC) in the treatment of cesarean scar pregnancy (CSP).METHODS:A total of 90 CSP patients were randomly divided into group A and B,with 45 cases in each group.Group A was given Methotrexate (MTX) injection 50 mg/m2 intravenously before CCUC.Group B received Seldinger catheterization in supine position before CCUC,and was given sequential infusion of MTX injection 50 mg/m2 and gelatin sponge particles into the uterine artery;the catheter was removed after satisfactory embolization by imaging examination.The levels of β-HCG of 2 groups were reexamined every 24 h,and CCUC was performed when serum β-HCG level was below 1 000 mU/mL.Perioperative bleeding volume,postoperative bleeding volume,the time of blood β-HCG returning to normal,the time of menstruation returning to normal,hospitalization time as well as the lesion diameters,the levels of blood β-HCG,the occurrence of compliance and ADR before and after treatment were compared between 2 groups.RESULTS:The intraoperative bleeding amount and postoperative bleeding amount of group B were significantly lower than those of group A,while the time of blood β-HCG returning to normal,the time of menstruation returning to normal and hospitalization time were significantly shorter than group A,and the incidence of total compliance was significantly lower than group A,with statistical significance (P＜0.05).Before medication,there was no statistical significance in lesion diameters between 2 groups (P＞0.05).Before CCUA,the lesion diameters of 2 groups were significantly smaller than before medication,and the group B was significantly smaller than group A,with statistical significance (P＜0.05).Before medication,there was no statistical significance in blood β-HCG levels between 2 groups (P＞0.05).Before and after CCUC,blood ββHCG levels of 2 groups were significantly lower than before medication,and the group B was significantly lower than group A,with statistical significance (P＜0.05).There was no statistical significance in the incidence of ADR between 2 groups (P＞0.05).CONCLUSIONS:Compared with methotrexate by intravenous drip,methotrexat by uterine artery embolization combined with CCUC for CSP can effectively reduce intraoperative bleeding amount,promote the decrease of blood β-HCG and menstrual recovery,and contribute to the reduction of complication risk with good safety.

Objective:To analyze clinical and imaging features of Sturge-Weber syndrome in children.Methods:Clinical data were collected from 27 children with Sturge-Weber syndrome in Xuzhou Children′s Hospital, Xuzhou Medical University from July 2013 to December 2019, and analyzed retrospectively.Results:Among the 27 children, 17 were males and 10 were females. Their age at the clinic visit ranged from 2 days to 10 years and 7 months, and averaged 2.54 years. All the 27 patients presented with facial port-wine stains of varied color from light red to purple red, which were all distributed across the facial midline, including 21 with predominantly unilateral port-wine stains and 6 with bilateral symmetrical port-wine stains. There were 17 patients with ocular choroidal vascular malformations, including 14 with congenital glaucoma, 5 with high intraocular pressure, and 1 with optic nerve atrophy accompanied by transient blindness. Neurological impairment occurred in 12 patients, and all manifested as epilepsy. All the 27 children underwent imaging examination, and abnormalities were found in 20. Among the 10 patients with abnormal computed tomography images, local calcification was observed in 8, and local thickening of the skull on the side affected by skin lesions in 8; 13 of 14 patients with abnormal magnetic resonance imaging scan results had signs of brain atrophy, 9 showed enhanced gyrus-like blood vessel formation by enhanced magnetic resonance imaging, and 5 showed decreased branches of the anterior and middle cerebral artery on the affected facial side by magnetic resonance angiography.Conclusions:Children with Sturge-Weber syndrome are clinically characterized by predominantly unilateral port wine stains on the face, some of whom are accompanied by epilepsy, glaucoma or mental retardation, and imaging examinations mainly show local calcification, brain atrophy, local thickening of the skull plate, enhanced gyrus-like blood vessel formation, etc. Early definite diagnosis and comprehensive systemic treatment are needed to reduce disability and mortality rates in patients with Sturge-Weber syndrome, and long-term follow-up should be considered.
