ABSTRACT: To investigate flow in the ductus venosus at 11-13 + 6 weeks of gestation in women with normal pregnancies in the Taiwanese population.
Two hundred and fifty-two normal singleton pregnancies with gestational ages ranging from 11 to 13 + 6 weeks were examined in this study. The pulsatility index for veins (PIV), resistance index (RI), peak velocity during ventricular systole (S-wave), and peak velocity during ventricular diastole (D-wave) were recorded from the ductus venosus.
We analyzed 252 participants who all fulfilled the inclusion and exclusion criteria of our study. The mean maternal age was 31 (range 19-45 years), with a corresponding gestational age of 12 + 4 weeks (range 11-13 + 6). No significant change was found in the vascular indices as gestational age increased for the S-wave (S-wave = 1.4214 (GA) + 17.448, r = 0.09, P = 0.154), PIV (PIV = -0.0358 (GA) + 1.4143, r = -0.05, P = 0.378) and RI (RI = -0.035 (GA) + 1.1478, r = -0.064, P = 0.468). In contrast, the D-wave behaved differently from the other variables. There was a significant increase (r = 0.155, P = 0.013) in the D-wave with gestational age (D-wave = 1.4896 (GA) - 7.1547).
D-wave velocity in the ductus venosus increased with gestational age. S-wave peak velocity showed an increasing trend and PIV showed a decreasing trend with gestational age, but they did not reach statistical significance.

ABSTRACT: To assess parameters of 3-dimensional power Doppler ultrasound in differentiating an endometrioma from other hypoechogenic adnexal cysts.
We collected 58 patients with classic-appearing endometriomas (homogeneous hypoechogenic adnexal cysts with round shapes) on a 2-dimensional conventional sonography. The serum level of CA-125, parameters of 3-dimensional pelvic ultrasound including the volume of the cyst, the mean grey value (MGV), and three vascular indices: vascularization index, flow index, and vascularization flow index, were measured and then, after surgical intervention, were compared between the group with histologically proven endometriomas and the group with other histological diagnoses.
In the chocolate cyst group, the parity was significantly lower (0.68±0.17, p=0.012). The MGV and lesion volume of histologically proven endometriomas were significantly lower (14.78±0.7; 118.34±15.5) than those of other hypoechogenic benign adnexal cysts (17.17±0.74; 227.18±47.46), and the p values were 0.038 and 0.041, respectively. No differences in vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were found between the two groups. No relationship between lesion volume and MGV in the two groups, either (p=0.127 and 0.353). We also found little correlation between CA-125 and the volume of a histologically proven endometrioma as well as between CA-125 and its MGV.
MGV might be useful to differentiate an endometrioma from other homogeneous hypoechogenic adnexal cysts.

ABSTRACT: The aim of this study was to compare the effectiveness of transvaginal power Doppler sonography with spectral Doppler analysis as an aid in preoperatively distinguishing primary ovarian carcinoma and metastatic carcinoma to the ovary (Krukenberg tumors).
Fifty women with ovarian disease were preoperatively examined with transvaginal power Doppler sonography. Six basic parameters were measured, including intratumoral peak systolic velocity, end-diastolic velocity, time-averaged maximum velocity, pulsatility index (PI), resistive index (RI), and velocity index (VeI). Blood flow analyses were detectable in all patients. Twelve patients with metastatic carcinoma to the ovary were classified as group 1; 38 patients with primary ovarian carcinoma were classified as group 2. Comparison of intratumoral blood flow analyses between the two groups was performed.
The PI, RI, and VeI were significantly lower in patients with metastatic carcinoma to the ovary than those with primary ovarian carcinoma (P < .05). There were no significant differences in the peak systolic velocity (P = .871), end-diastolic velocity (P = .508), and time-averaged maximum velocity (P = .850) between the two groups.
Transvaginal power Doppler sonography with spectral Doppler analysis is an effective method in evaluating intratumoral blood flow of Krukenberg tumors. Low impedance (PI, RI, and VeI) might assist us in making differential diagnoses between primary ovarian carcinoma and Krukenberg tumors according to our preliminary results.

ABSTRACT: We present a case of fetal complete atrioventricular block, diagnosed by the M mode of two-dimensional ultrasound, that was complicated with polyhydramnios and bilateral hydrocele.
The fetus was delivered at 38 weeks' gestation by caesarean section. Postpartum autoimmune survey disclosed positive anti-Ro antibodies (SS-A) for both the mother and the newborn. Severe neonatal bradycardia with complete atrioventricular block was identified.
Antenatal evaluation for a maternal history of autoimmune disease (especially systemic lupus erythematosus) and prevention of fetal bradycardia by reducing immune-mediated injuries on the cardiac conduction system are important.

ABSTRACT: We present the first report of mosaic isochromosome 10p associated with multiple congenital anomalies including megacisterna magna, echogenic focus of the left ventricle, umbilical cord cysts, and distal arthrogryposis. The most obvious anomalies found on prenatal ultrasound were enlarged cisterna magna and lower limb flexion contractures which resembled clubfeet. Analyses of GTG-banded chromosomes of 42 cells harvested from 32 independent tissue culture colonies were examined. Thirty-five cells from 27 colonies had 46 chromosomes and appeared to be 46,XX, female karyotype. Seven cells from independent colonies had 47 chromosomes with abnormal karyotypes. The extra chromosome material was identified as isochromosome 10p without involvement of the heterochromatic region of the long arm [47,XX,+ i(10p)]. Mosaic tetrasomy 10p was confirmed using fluorescent in situ hybridization (FISH) of a 10p-specific probe to metaphase chromosomes of this patient.

ABSTRACT: We present the first case of a fetus with pure tetrasomy 20p proven by cord-blood sampling at 24 weeks of gestation. This case was diagnosed in utero with multiple congenital anomalies including occipital encephalocele, mega-cisterna magna, mesomelic shortening, and clubfeet. An analysis of GTG-banded chromosomes of 20 metaphase cells was performed. Female karyotype [47,XX, +i(20)(p10)] was revealed in all cells. Pure tetrasomy 20p was confirmed using fluorescent in situ hybridization (FISH) with a telomere probe for chromosome 20p in all seven metaphase cells. The pregnancy was terminated because of associated multiple anomalies and severe oligohydramnios. The postmortem examination confirmed the prenatal diagnosis.

ABSTRACT: Laparoscopic bipolar coagulation of uterine vessels (LBCUV) is reported to treat clinically symptomatic myomas that caused severe menorrhagia, but the viability of pregnancy after operation is unknown. A woman with clinically diagnosed uterine myomas, possibly with adenomyosis, had unexpected early pregnancy diagnosed at the time of LBCUV. The procedure resulted in improvement of menorrhagia to normal menstruation and reductions in the volume of both uterus and myomas. The intrauterine pregnancy was terminated at the woman's request. Pregnancy may be possible after LBCUV, although none has been reported.

ABSTRACT: Study ObjectiveTo determine the safety and side effects that may be caused by laparoscopic-assisted uterine depletion (LAUD) of submucous myomas.DesignRetrospective chart review and follow-up (Canadian Task Force classification II-2).SettingUniversity-affiliated tertiary referral center.PatientsFive hundred twenty women with symptomatic myomas warranting surgical treatment, who wished to retain their uteri.InterventionLaparoscopic bipolar coagulation of uterine arteries and anastomotic sites of uterine arteries with ovarian arteries.Measurements and Main ResultsPostoperative sonographs showed submucous myomas in 53 (10.2%) women. During follow-up for a mean of 8.6 months very few complications occurred; however, nine women (1.7%) experienced vaginal expulsion of myomas from 2 weeks to 5 months postoperatively. Four of them were readmitted within 43 days with high fever and fetid discharge, and cervical cultures revealed heavy growth of Escherichia coli in three. Vaginal myomectomy was performed in six patients, and one woman passed the myoma spontaneously. Histopathologic studies of these nine specimens showed that two had infarction, three had coagulative necrosis, and four had degeneration. After treatment, all nine women had normal menstruation and their symptoms resolved during follow-up of at least 3 months.ConclusionIn our experience LAUD led to satisfactory symptomatic improvement and reduction in myoma volume and few complications. If vaginal expulsion of submucous fibroids can be viewed as a side effect, we should pay close attention to women with submucous myomas, especially within 2 months of LAUD. Otherwise, more dangerous complications could occur.
