Is an Intrauterine Device a Contraindication for Uterine Artery Embolization? A Study of 20 Patients

Risk Factors of Complications After Uterine Artery Embolisation for Symptomatic Fibroids: A Case-Control Study

OBJECTIVE

We aim to clarify potential risk factors of complications after uterine artery embolisation (UAE).

SETTING

Complications after uterine artery embolisation (UAE) for symptomatic fibroids are rare, but failure of treatment occurs for approximately 13%-24% of patients at 10 years.

DESIGN

We conducted a case-control study including all complications post UAE over 15 years in our specialised unit.

POPULATION

All Grade 2 complications (or worse) for the Society of Interventional Radiology Standards of Practice Committee complications post UAE were considered. One thousand one hundred seventy-two UAE were performed.

METHODS

Complications were divided into two groups: early (< 1 month) or late (≥ 1 month) to differentiate complications from failure of procedure. Multinomial analysis was conducted to assess links between complications and potential risk factors.

RESULTS

Sixty-nine (0.06%) complications were found: 24.6% hospitalisation for pain (n = 17/69), 30.4% for infection (n = 21/69) and 2.9% expulsion of fibroid (n = 2/69). Overall, 31 patients underwent a second procedure (45%).

MAIN OUTCOME MEASURES

Intra-uterine device and multiple fibroids were strongly related to early complications (ORearly = 4.44, IC 95%: 1.5-13.3 and ORearly = 3.7, IC 95%: 1.2-11.3, respectively). The only factor that appeared to be associated with risk of early and late complications was the major fibroid's diameter (for an increased size of 25 mm, ORearly = 1.7, IC 95%: 1.1-2.6; ORlate = 1.5, IC 95%: 1.04-2.2).

CONCLUSION

Our study enlightens about the potential risk factors of UAE's complications and differentiate their impact between early and late complications.

Current Strategies for Prevention of Infection After Uterine Artery Embolisation

Uterine artery embolisation (UAE) is a safe and effective procedure for symptomatic uterine fibroids with an estimated rate of post-operative intra-uterine infection of 0.9-2.5%. While rates of infection have remained low over the past two decades, there is variation in infection prevention practices. Intra-uterine infection after UAE may occur via access site haematogenous spread or ascension of vaginal flora through the cervical canal. Although the evidence base is immature, risk factors for infection including previous pelvic infection, hydrosalpinx, endocervical incompetence, diabetes, smoking, obesity, respiratory disease, and immunosuppression should be assessed during the pre-operative consultation with the interventional radiologist to tailor a plan for minimising infection, which may include optimisation of any modifiable risk facts and prophylactic antibiotics.

Pain after uterine artery embolization with intrauterine device in situ

Uterine artery embolization (UAE) is a minimally invasive option for females with symptomatic leiomyomas. Studies detailing a possible risk with an intrauterine device (IUD) in situ during UAE are limited. A 43-year-old female (Gravida 2, Para 2) underwent UAE with an IUD in situ. On post-procedure day 2, the patient presented with severe lower abdominal pain and mild leukocytosis. Following removal of her IUD, the patient experienced immediate pain relief. Caution is given to clinicians who wish to perform UAE with an IUD in situ.

Uterine artery embolisation in women with symptomatic uterine fibroids

The most common indication for selective uterine artery angiography is embolisation of symptomatic uterine fibroids (leiomyomas or leiomyomata). It is a safe and effective treatment with worldwide acceptance and may be considered a first-line therapy for women who are finished with childbearing and interested in a minimally invasive uterine-sparing therapy, with only few relative and absolute contraindications remaining. Women interested in pregnancy may be offered embolisation, but only after careful counselling and consideration of other possibilities and patient's reasonable expectations, needs and preferences.

Uterine artery embolization in the treatment of symptomatic fibroids - state of the art 2018

Uterine fibroids are considered to be the most common benign tumours in females. The vast majority of these tumours are incidental findings and do not require any treatment. Symptomatic fibroids, with ailments such as abnormal uterine bleeding, dysmenorrhoea, pelvic pain, impaired urination, bowel dysfunction, infertility, and recurrent pregnancy loss, are indicated for medical treatment. Surgery remains a first-line treatment of symptomatic uterine fibroids; however, minimally invasive techniques and pharmacological management have become more available and popular. Among minimally invasive techniques uterine artery embolization (UAE) is the most well-established uterine preserving treatment. UAE was first introduced in obstetrics and gynaecology in 1987 and since then many studies have shown the safety and efficacy of UAE in fibroid treatment with low rates of complications. In this review we present a novel approach to UAE, which reflects the current state of knowledge based on recent clinical trials and long-term post-procedural follow-up.

Pyomyoma After Uterine Artery Embolization: Laparotomy Avoided by In-Bag Morcellation

We report a case of a pyomyoma in which in-bag morcellation allowed for a total laparoscopic hysterectomy instead of laparotomy, which has been recognized as the standard of care to avoid the spread of infection from morcellation. A 45-year-old multiparous woman presented with sepsis, pelvic pain, and leukocytosis at 1 month after undergoing uterine artery embolization for symptomatic uterine leiomyoma. Pelvic computed tomography scan revealed a 9-cm suspected pyomyoma. A total hysterectomy was performed using a laparoscopic approach with in-bag morcellation. The intervention was successful, and the postoperative course was uneventful. The patient was discharged on postoperative day 1 and was well at 2 months after surgery.

Updates on Uterine Artery Embolization

Uterine fibroids (leiomyomas) are the most common benign neoplasm of the female pelvis and have a lifetime prevalence exceeding 80% among African American women and approaching 70% among Caucasian women. Approximately 50% of women with fibroids experience symptoms which may include menorrhagia that may result in anemia, bulk symptoms with bladder and bowel dysfunction and abdominal protrusion, dysmenorrhea, and infertility. Hysterectomy remains the most common treatment option for fibroids and concerns have been raised about the overuse of this procedure. Uterine artery embolization (UAE) is now a well-established uterine preserving and minimally invasive therapy for symptomatic fibroids. Since its introduction, strong evidence for safety and efficacy of UAE has been generated with low rates of complications. This review will discuss UAE for the management of symptomatic uterine fibroids with special focus on emerging technical approaches and novel periprocedural patient care.

Preprocedural MRI and MRA in planning fibroid embolization

This pictorial review aims to discuss and illustrate the up-to-date use of preprocedural magnetic resonance imaging (MRI) in selecting patients and planning uterine artery embolization (UAE). The merits of magnetic resonance angiography (MRA) in demonstrating the pelvic vasculature to guide UAE are highlighted. MRI features of fibroids and their main differential diagnoses are presented. Fibroid characteristics, such as location, size, and enhancement, which may impact patient selection and outcome, are presented based on recent literature. Pelvic arterial anatomy relevant to UAE, including vascular variants are illustrated, with conventional angiography and MRA imaging correlation. MRA preprocedural determination of the optimal projection angles for uterine artery catheterization is straightforward and constitutes an important strategy to minimize ionizing radiation exposure during UAE. A reporting template for MRI/MRA preassessement of UAE for fibroid treatment is provided.

Management of Uterine Fibroids: A Focus on Uterine-sparing Interventional Techniques

Uterine fibroids occur in approximately 50% of women over the age of 40 years, and an estimated 50% of those are symptomatic. Menorrhagia is the most common symptom and the primary indication for treatment, although bulk symptoms often occur and can be treated. Pharmacotherapy is typically inadequate unless it can be expected to successfully bridge to menopause or allow for a less-invasive intervention. However, hormonal therapies have risks. Hysterectomy is still the most commonly performed procedure for symptomatic fibroids and has the lowest rate of reintervention (compared with myomectomy or uterine artery embolization [UAE]), but rates of more serious complications are higher and patient satisfaction and ability to return to normal activities may also be less favorable. Myomectomy is not necessarily less morbid than hysterectomy and may have a greater failure rate than UAE. Techniques and devices vary with little standardization, and operator experience is crucial to success. The largest studies of UAE show very low rates of serious complications and rapid recovery. UAE significantly improves symptoms related to uterine fibroids in 85%-90% of patients. Herein, this article will discuss the nature of fibroids and their diagnosis, pharmacotherapy, surgical treatment, and nonsurgical interventional treatment, including UAE and magnetic resonance-guided focused ultrasound.

Overview of latest evidence on uterine fibroids

Uterine fibroids are the most common type of benign gynecologic mass, and are present in up to 80 percent of women. Research exploring risk factors for fibroids presents conflicting or inconclusive findings. Symptoms for up to 50 percent of women experiencing fibroids include heavy menstrual bleeding, pelvic pressure or pain and gastrointestinal and genitourinary changes. Diagnosis is made by history and symptoms, physical examination and imaging. Several treatment options are available, and are based on symptoms, preferences and reproductive plans. Given the high prevalence of fibroids and the potential for women's health implications, it is essential that clinicians are aware of the latest evidence regarding fibroids to provide the highest quality of care for women whose health is affected by this condition.
