Complication Analysis Of 1201 Uterine Artery Embolization Cases

ObjectiveTo count the incidence rate of complications of uterine artery embolisation, and to evaluate its security.MethodFrom 2011.1 to 2015.9,1201 patients undergoing uterine artery embolisation in Womens Hospital School of Zhejiang University were studied retrospctively, including their clinical meterial, outpatient follow-up and telephone follow-up.Result 1201 cases aged from 16 to 55, with an average of 32.54±5.02. The causes to receive UAE are mainly CSP(86.6%), following cervical pregnancy(4.5%), placenta previa (3.4%), placenta imlantation (2.2%), postpartum hemorrhage(1%). Other causes include postoperation hemorrhage, gestational trophoblastic tumor, residual pregnancy tissue, neoplasm in uterine cavity, hysteromyoma, arteriovenous fistula. The most comlication is postembolisation syndrome(94.84%),following complications of urinary system(4.08%), hypersensitivity to contrast media(1.75%), nerve injury(1.33%), ovarian dysfunction(0.84%), vascular injury(0.25%), intrauterine infection(0.08%). Severe complications are ureteral obstruction associated with hydronepherosis(0.17%) and premature ovary failure(0.12%).ConclusionUAE is safe in prevent and treat uterine hemorrhage, especially in CSP, with a low incidence of severe complications. To ureteral obstruction associated with hydronepherosis, to recognize early and dispose in time is important to the prognosis of patients. As to the low chance of pregnancy of premature ovary failure, full communication and weighting the advantages verses disadvantages is necessary to those young and with reproduction requirement.
