11/41. Partial hydatidiform mole following the transfer of single frozen-thawed embryo subsequent to ICSI.Hydatiform mole is a gestational trophoblastic disease characterized by the dominance of dispermic fertilization. micromanipulation techniques in assisted reproduction technologies have enabled direct evaluation of the zygotes and the formation of pronuclei in the zygote. Intracytoplasmic sperm injection (ICSI) of oocytes ensures that only a single spermatozoon enters the ooplasma. This study reports a case of partial hydatiform mole following the transfer of day 3 frozen-thawed embryo. ICSI was used as the assisted fertilization method because there was male factor infertility due to severe oligoasthenoteratozoospermia. Possible predisposing factors for partial hydatidiform mole after ICSI are also discussed.- - - - - - - - - - ranking = 1keywords = fertilization (Clic here for more details about this article) |
12/41. Partial hydatidiform mole.A case of partial hydatidiform mole is presented, occurring in a young primiparous woman after natural conception. She presented with incomplete miscarriage. Histological diagnosis of partial mole was made. Failure of beta HCG to fall resulted in the start of chemotherapy. WHO scoring placed her in low risk group. In spite of the low risk, she required third line chemotherapy for complete eradication of disease.- - - - - - - - - - ranking = 0.043695819306576keywords = conception (Clic here for more details about this article) |
13/41. First trimester diagnosis of partial mole.BACKGROUND: Partial mole is one of the two distinctive subtypes of hydatidiform mole. It is usually paternally derived triploid conceptions in which embryonal development occurs in association with trophoblastic hyperplasia. The definite diagnosis is confirmed by pathological and cytogenetic studies. Ultrasound might be helpful to diagnose partial mole in the first trimester. CASE: A 25-year-old woman, gravida 2, para 0-0-1-0, was initially seen for antenatal care at 6 weeks' pregnant. Ultrasound was undertaken at 13 weeks' pregnancy due to her first fetal anomaly, which demonstrated partial mole and embryonic death. The serum beta hCG was 190,900 mIU/ml. suction curettage was performed without complication. Histopathological study confirmed partial mole and cytogenetic study of the placenta revealed an uncommon karyotype, mosaicism of triploid (69,XXX/69,XXY). serum beta hCG was declined and negative at 8 weeks. The patient was well and serum beta hCG remained normal throughout 6 months of follow-up. CONCLUSION: Although the majority of partial mole pregnancies cannot be detected by routine first trimester ultrasound examination, first trimester ultrasound can be helpful in some cases, such as this one. If partial mole is sonographically suspected, it should be confirmed with histopathology and cytogenetic studies. The management is similar to complete mole including prompt evacuation and careful monitoring of beta hCG.- - - - - - - - - - ranking = 0.043695819306576keywords = conception (Clic here for more details about this article) |
14/41. Magnetic resonance experience of a twin pregnancy with a normal fetus and hydatidiform mole: a case report.A case of twin pregnancy with a coexistent hydatidiform mole after in vitro fertilization is presented. Prenatal magnetic resonance (MR) imaging at 20 gestational weeks demonstrated a normal fetus and a distinct junction between the molar tissue and myometrium suggesting no evidence of myometrial invasion. Clinically, the rare disease entity involves a high risk of maternal complications and intrauterine fetal death. The application of ultrafast MR imaging for prenatal examination provides important additional information for prenatal counseling and obstetric management.- - - - - - - - - - ranking = 0.5keywords = fertilization (Clic here for more details about this article) |
15/41. Severe intrauterine growth restriction associated with the development of a submucosal leiomyoma during pregnancy: a case report.BACKGROUND: Small, intramural leiomyomas are not generally considered a risk factor for poor reproductive outcomes. CASE: A patient with a 6-mm intramural leiomyoma and a normal uterine cavity by hysteroscopic evaluation who conceived after in vitro fertilization developed severe early-onset intrauterine growth restriction (IUGR), leading to pregnancy termination at 23.4 weeks' gestation. At 6 weeks postpartum, a 1.7-cm, intracavitary leiomyoma was detected on ultrasound evaluation and removed by hysteroscopic resection. The patient conceived in a subsequent in vitro fertilization cycle and gave birth to monozygotic twins with appropriate weights at 34 weeks of gestation. In the absence of other identifiable etiologies of the IUGR, it is plausible that the small, intramural leiomyoma enlarged and migrated into the cavity, causing abnormal placentation and leading to fetal growth restriction in the first pregnancy. CONCLUSION: Uterine cavity reevaluation is recommended in the investigation of IUGR before a woman attempts further pregnancies.- - - - - - - - - - ranking = 1keywords = fertilization (Clic here for more details about this article) |
16/41. Two successful pregnancies after in vitro fertilization and embryo transfer in a patient with endometrial atypical hyperplasia bordering on adenocarcinoma treated conservatively with high-dose progesterone.women suffering from anovulatory infertility may develop endometrial hyperplasia and adenocarcinoma due to the unopposed estrogen effect. We present the case of a young infertile woman with endometrial atypical hyperplasia bordering on adenocarcinoma who refused hysterectomy and bilateral salpingo-oophorectomy and achieved two successful pregnancies after conservative treatment with high-dose progesterone followed by in vitro fertilization and embryo transfer. It is concluded that conservative treatment with high-dose progesterone for endometrial hyperplasia and well-differentiated early-stage adenocarcinoma followed by assisted reproductive technologies is an appropriate means for achieving pregnancy. However, the issue of hysterectomy and bilateral salpingo-oophorectomy after delivery or after fertility being no longer required is controversial. If surgery is not performed, close observation with endometrial sampling every 6 months is advisable.- - - - - - - - - - ranking = 2.5keywords = fertilization (Clic here for more details about this article) |
17/41. Simultaneous endometrioid ovarian and uterine carcinoma diagnosed after an in vitro fertilization procedure--case report and review of the literature.BACKGROUND: The presence of simultaneous carcinomas involving both the ovary and uterus is relatively uncommon, while the possible link between fertility drugs and carcinogenesis still remains controversial. CASE: The case of a 40-year-old patient with simultaneous aggressive endometrioid carcinoma of the ovary and uterus a few months after the sixth attempt of in vitro fertilization is presented. The patient had de novo lung disease at surgery and diffuse metastatic spread to adjacent bone, subcutaneous tissue and the central nervous system (CNS) soon after a spectacular response to the primary paclitaxel/carboplatinum chemotherapy and while on maintenance and second-line chemotherapy, respectively. CONCLUSION: The fulminating course of our patient might in part be attributed to the existence of advanced disease at presentation. Definite conclusions about the possible association with the previously performed assisted reproduction cannot be drawn but close clinical surveillance of such patients before, during and after infertility treatment is strongly warranted.- - - - - - - - - - ranking = 2.5keywords = fertilization (Clic here for more details about this article) |
18/41. Complete hydatidiform mole and normal live birth following intracytoplasmic sperm injection.A twin pregnancy with complete hydatidiform mole (HM) and preterm birth of a normal female infant after intracytoplasmic sperm injection (ICSI) conception was experienced. ICSI due to severe oligozoospermia was performed on three ova, and three embryos with confirmed two proneclei (2PN) were subsequently transferred to the uterus. At 7 weeks of gestation, molar pregnancy as well as a viable fetus was recognized. At 33 weeks, the pregnancy was terminated due to preterm labor. Dichorionic pregnancy consisting of a normal fetus and placenta in one chorionic membrane and complete HM in the other was recognized. Cytomolecular analysis indicated that the complete HM genome was derived from duplication of a single sperm, and a normal neonate was from biparental genomes. It should be noted that ICSI can avoid incomplete HM (mostly triploid) due to multi-sperm fertilization but might not be able to avoid complete HM (paternal diploid) although such a risk is very low. This is the second report of this condition and is accompanied by the first well-described molecular analysis.- - - - - - - - - - ranking = 0.54369581930658keywords = fertilization, conception (Clic here for more details about this article) |
19/41. Subserosal pregnancy in a previous myomectomy site: a variant of intramural pregnancy.A 35-year-old woman with a history of myomectomy underwent in vitro fertilization and became pregnant. Transvaginal ultrasound revealed a gestational sac within the subserosal area of the posterior uterine wall. The patient was treated successfully with conservative surgery, and the pathologic evaluation of the excised mass demonstrated chorionic villi involving myometrium. Early in a subsequent pregnancy, placental invasion through the sinus tract was detected. However, the pregnancy outcome was uneventful. This constitutes the first report of subserosal implantation in the uterine body. Our findings suggest that the probable pathogenesis of this rare variant of intramural pregnancy is implantation through a sinus tract made during a previous uterine surgery.- - - - - - - - - - ranking = 0.5keywords = fertilization (Clic here for more details about this article) |
20/41. Pregnancy following regression of uterine submucosal leiomyoma with GnRH therapy; a case report.A patient with a history of two spontaneous abortions, at the 16th and 20th week, respectively, and one intra-uterine fetal death at the 26th week of gestation was investigated. The sole abnormal condition that could be evidenced was a submucosal leiomyoma of 56 mm in diameter in the uterine fundus. Administration of gonadotropin/releasing hormone analog (GnRHa) for 10 months resulted in complete disappearance of myoma. Direct intraperitoneal insemination following induction of ovulation resulted in pregnancy. In a patient harboring uterine leiomyomas, adversely affecting conception and pregnancy outcome, GnRHa treatment may be an initial approach allowing to avoid pelvic surgery. As the beneficial effect of GnRHa might be temporary, assisted reproduction procedures might anticipate conception.- - - - - - - - - - ranking = 0.087391638613153keywords = conception (Clic here for more details about this article) |
