Evaluation of cavity before ART: Saline Infusion Sonohysterography
IVF and IMPLANTATION • Implantion rates are still low after IVF (%10- • 25(a)). İmplantation failure is related to • inadequate endometrial receptivity (2/3) • embryo (1/3) (b) • Increase in endometrial receptivity leads to • İncrease in pregnancy rates • Decrease in early pregnancy losses • Decrease in multipl pregnancies • (a) de los Santos et al., 2003 • (b) Simon et al., 1998;Ledee-Bataille et al., 2002
When implantation fails to occur despite the transfer of chromosomally normal good quality embryos, other factors that may impede implantation must be affecting implantation: • Endometritis, • endocrine abnormalities, • thrombophilias, • immunologic factors • congenital and acquired anatomic factors
Methods to evaluate uterine cavity • Hysterosalphingography (HSG) • Transvaginal ultrasonography (TVU) • Saline infusion sonohysterography (SIS) • Office hysteroscopy (OHS) • Diagnostic hysteroscopy
Possible uterine factors associated with implantation failure in IVF • Uterine submucous fibroids • Endometrial polyps • İntrauterine adhesions • Congenital uterine anomalies
Saline Infusion Sonohysterography • Use of SIS in general infertile population • Use of SIS to evaluate cavity before ART
Use of SIS in general infertile population Histeroskopinin avantajı aynı anda tedavi imkanı

Which infertile women should be indicated forsonohysterography? Conclusions TV-SCSH should be performed on selected patients following assessment of endometrial images on transvaginal sonography in order to diagnose intra- and pericavitary lesions in infertile women
Saline Infusion Sonohysterography • Use of SIS in general infertile population • Use of SIS to evaluate cavity before ART
Uterine cavity assessment prior to IVF • No statistically significant difference was observed in the pregnancy outcome for patients undergoing IVF who had sonohysterography compared with that for patients undergoing IVF during the same period who previously had a uterine evaluation by a different method. • Conclusion(s): Sonohysterography offers advantages over in-office hysteroscopy and hysterosalpingography for evaluation of the uterus before IVF.

Uterine cavity assessment prior to IVF Conclusions: SCHS in comparison with H/S: 87.5 sensitivity, 100% specificity, 100% PPV, 91.6 NPV. TVUS in comparison with H/S: 81 sensitivity, 95% specificity, 93% PPV, 86 NPV. However; unlike SCHS, TVUS (1) could not could not diagnose submucosal fibroids in the presence of multiple fibroid uterus (2) distinguish between a hyperplastic endometrium and a large polyp; or (3) differentiate between an arcuate and a septate uterus Ayida G et al. Ultrasound Obstet Gynecol 1997
Uterine cavity assessment prior to IVF • SIS was performed in 80 patients before ICSI and compared with 240 cycles in patients with normal HSG • A subsequent hysteroscopy was undertaken in patients with intracavitary lesions • Clinical pregnancy rates were comparable between groups (40.2% vs 42.5%) • SIS appears to be a simple, inexpensive and safe alternative to HSG for the evaluation of uterine cavity before IVF/ICSI Alatas et al Hum Reprod 1998
Role of saline infusion sonography in uterineevaluation before frozen embryo transfer cycleGera et al Fertil& Steril 2008 group A: positive SIS findings and treated group B: positive SIS findings and not treated group C : negative SIS findings
In an IVF program, SHG as an outpatient diagnostic method is easy, sensitive, and well tolerated.
Conclusions: • compared with hysteroscopy, SHG seems to offer similar diagnostic capabilities in at least some studies in assessing uterine cavity. It is also less invasive and costly. • In comparison with HSG, SHG has been found superior for evaluation of the uterus. It has a higher sensitivity, better tolerated, does not require the use of radiation, and provides better diagnostic accuracy. • larger, prospective, randomized studies has to be designed to draw a definite conclusion regarding the efficiency of SHG before ART
