Clinical, Imaging and Procedural Risk Factors for Intrauterine Infective Complications After Uterine Fibroid Embolisation: A Retrospective Case Control Study

Introduction This was a retrospective case–control study at a single tertiary centre investigating all UFE procedures between January 2013 and December 2018 for symptomatic fibroids. The aim was to determine the clinical, imaging and procedural risk factors which impact upon the risk of post-uterine fibroid embolisation (UFE) intrauterine infection. Cases were patients which developed intrauterine infection post-procedure, and controls were the background UFE population without infection. Methods Clinical demographics, presenting symptoms, uterine and fibroid characteristics on imaging and procedural variants were analysed. A p value of less than 0.05 was considered statistically significant. The main outcome measures were presence of infection and requirement of emergency hysterectomy. Results 333 technically successful UFE procedures were performed in 330 patients. Infection occurred after 25 procedures (7.5%). 3 of these patients progressed to overwhelming sepsis and required emergency hysterectomy. Clinical obesity (BMI > 30) (OR 1.53 [1.18–1.99]) and uterine volume > 1000cm3 (2.94 [1.15–7.54]) were found to increase the risk of infection Conclusions UFE is generally safe in patients with symptomatic fibroids. Obese patients (BMI > 30) and those with large volume uteri (> 1000cm3) are at slight increased risk of developing infection and require appropriate pre-procedural counselling, as well as careful post-UFE follow-up. BMI and uterine volume may be useful to assess before the procedure to help to determine post-UFE infection risk.

Uterine Fibroid Embolization via Transradial versus Transfemoral Arterial Access: Technical Results

AIM: This study was designed to compare the safety and feasibility of uterine fibroid embolisation (UFE) via transradial access (TRA) and transfemoral access (TFA). MATERIAL AND METHODS: A retrospective analysis was conducted for 2 cohorts: 13 cases with already established TFA (from February 2016 to September 2018) and the first 11 procedures performed via TRA (from October 2017 to October 2018). Indications for embolization included: heavy menstrual bleedings (n = 18), lower urinary tract symptoms (n = 2), pelvic pain (n = 3) and abdominal pain (n = 1). One interventional radiologist and one fellow performed all procedures at one institution. Technical success, procedural time, access site complications as well as feedback from patients were assessed for analysis. RESULTS: Technical success was achieved in 24/24 cases (100%). Unilateral uterine artery embolisation was performed in 7 cases (29.1%) and bilateral in 17 cases (70.8%). Mean procedure time was 72.4 minutes in TFA group, and 60.3 minutes in the TRA group. Mean fluoroscopy time was 25.3 minutes in the TFA group and 21.1 minutes in the TRA group. Access site-related and overall adverse events did not vary significantly among the study cohorts. CONCLUSIONS: TRA represents a safe and feasible approach for UFE with a comparable safety profile to TFA.
