Advanced ultrasound examination in the management of subfertility

A review of complications following transvaginal oocyte retrieval for in-vitro fertilization

Transvaginal ultrasound guided oocyte retrieval (TVOR) during in vitro fertilization (IVF) treatment was first described in 1985. By virtue of its simplicity and effectiveness, it has gained widespread popularity and has now become the gold standard for IVF therapy. Nevertheless, despite the advantages, the aspiration needle may injure the adjacent pelvic organs and structures leading to serious complications. The most common complications are haemorrhage, trauma and injury of pelvic structures, and pelvic infection. Other complications described include adnexal torsion, rupture of endometriotic cysts, anaesthetic, and even vertebral osteomyelitis. In the last two decades, several reports have described the complications associated with this technique, and tried to address the risk factors and safety issues. However there is wide variation in the way this common procedure is performed, with room for improvement through published guidelines. This article reviews the most common complications reported in literature, summarizes the recommendations made to minimize their occurrence, and raises some of the controversial issues related to the procedure especially that of pelvic infection.

Doppler Evaluation of the Ovary: Clinical Applications and Challenges

Transvaginal sonography has been shown to be an accurate technique for discriminating between benign and malignant adnexal masses. Accurate preoperative differential diagnosis of adnexal masses is essential for optimizing patients’ treatment. The advancement and wider availability of therapies of assisted conception have occurred to a large extent as a result of developments in ultrasonography. Transvaginal color Doppler has opened up exciting new possibilities for the better understanding of the physiology and pathophysiology of ovarian blood flow, resulting in a number of completely new diagnostic parameters.

Assessment of three-dimensional sonographic features of polycystic ovaries after laparoscopic ovarian electrocautery

BACKGROUND

Treatment of polycystic ovary syndrome-related infertility includes laparoscopic ovarian electrocautery. Three-dimensional (3-D) sonographic characterization of polycystic ovaries has been performed recently, including the study of the effect of laparoscopic ovarian drilling on ovarian volume. The impact of laparoscopic treatment on ovarian volume and vascular flow-patterns assessed by 3-D color power angiography (CPA), however, has not yet been elucidated.

OBJECTIVE

To measure ovarian volume, to evaluate and quantify intraovarian blood flow with 3-D CPA histogram analysis before and after laparoscopic ovarian electrocautery, and to compare the hormonal effects of surgery with 3-D sonographic findings.

SETTING

University hospital.

PATIENT(S)

Ten patients, aged 18-34 years, with polycystic ovary syndrome.

INTERVENTION(S)

Evaluation of serum and urinary hormone profiles as well as transvaginal 3-D ultrasonography were performed before and after laparoscopic ovarian surgery.

RESULT(S)

Ovarian volume decreased, and 3-D CPA showed increased intraovarian flow intensity after laparoscopic electrocautery. Serum LH and T levels, ratios of urinary steroids reflecting 5 alpha-reductase enzyme activity, and androgen to cortisol metabolites decreased; serum FSH levels increased 1 week after laparoscopy and correlated well with changes of 3-D sonographic features. Seven patients ovulated regularly after surgery, and five pregnancies were conceived within 1 year.

CONCLUSION(S)

Three-dimensional ultrasonography may be a useful adjunct and noninvasive method for correlating clinical parameters with the blood flow alterations in polycystic ovary syndrome patients.

An ultrasound-based approach to the assessment of infertility, including the evaluation of tubal patency

An optimal initial infertility investigation protocol would be a process that is diagnostically accurate, expeditious, cost-effective, reliable and as minimally invasive as possible. In addition, the investigation should provide the clinician with useful prognostic information regarding possible future treatment. At present, extensive use of invasive procedures such as diagnostic hysteroscopy and laparoscopy is the standard at many fertility centres. Recent advances in gynaecological ultrasonography have shown that ultrasound can replace routine invasive investigative procedures. An ultrasound-based approach would make the basic infertility investigation less time-consuming and less expensive, but at the same time more acceptable to the majority of patients. This chapter describes an ultrasound-based approach to the assessment of infertility. In addition, the role of ultrasonography for assessment of the pelvic organs as a basic part of the initial investigation of an infertile couple is discussed and compared to more traditional invasive methods.

Investigation of the infertile couple: a one-stop ultrasound-based approach

The appropriateness of many investigations for subfertility will continue to be of debate for some time yet. Of most benefit to the concerned couple would be a process that is diagnostically accurate, expeditious and reliable. It should be performed with a minimum of invasion and provide both patient and clinician with useful prognostic information regarding possible future treatment. This article is intended to illustrate the advantages of an ultrasound-based process of subfertility investigation. Discussed is the role of ultrasound compared with more invasive investigative methods such as laparoscopy and hysteroscopy. In addition, the potential capacity of newer advanced ultrasound technologies is reviewed.
