RESUMO
Objectives: This study aimed to retrospectively review imaging findings and the outcomes of uterine artery embolisation (UAE) in symptomatic uterine vascular anomalies (UVA). Methods: This study included a total of 15 patients with acquired UVA admitted to the Aga Khan University Hospital in Karachi, Pakistan, from 2010 to 2020. These patients were evaluated using ultrasound, computed tomography and magnetic resonance imaging, either alone or in combination. All patients had a history of dilatation and curettage or uterine instrumentation and underwent angiography and embolisation of the uterine arteries. The primary outcome post embolisation was assessed clinically and/or in combination with ultrasound. Post-procedure pregnancies were also recorded. Results: Non-invasive imaging was abnormal in all patients; however, this pre-intervention imaging was unable to accurately classify the type of vascular anomaly, except in the case of a pseudoaneurysm. Conventional angiography showed uterine artery hyperaemia in six patients, arteriovenous malformation in seven patients and pseudoaneurysm in two patients. The technical success rate was 100% and no repeat embolisation was needed. The follow-up ultrasound in 12 patients revealed a resolution of the abnormal findings, while the remaining three were found to be normal on clinical follow-up. Seven patients (46.7%) had a normal pregnancy 15.7 months after the procedure (range: 4-28 months). Conclusions: UAE is a safe and effective management option for intractable severe bleeding in patients with UVA post instrumentation and it was found that the procedure does not impair future pregnancy.
