1/19. broad ligament twin pregnancy following in-vitro fertilization.We report the first case of an ectopic twin pregnancy in the broad ligament following in-vitro fertilization and embryo transfer in a patient with a previous ipsilateral (left) salpingo-oophorectomy. The previous surgery was for endometriosis. We discuss the possible contribution of the embryo transfer technique, limitations of preventive measures and importance of transvaginal ultrasound in establishing the diagnosis.- - - - - - - - - - ranking = 1keywords = fertilization (Clic here for more details about this article) |
2/19. salpingectomy for unilateral hydrosalpinx may improve in vivo fecundity.The objective of this study was to determine whether unilateral salpingectomy for hydrosalpinx could improve fecundity in women with an apparently normal contralateral tube. Two women with unilateral hydrosalpinx and with an apparently normal contralateral tube, and a long history of infertility, including failure to conceive despite several cycles of in vitro fertilization (IVF), had unilateral salpingectomies prior to considering subsequent IVF cycles. Case 1 conceived after 1 month following surgery and case 2 after 8 months without the use of assisted reproductive technology. Though the ensuing pregnancies may have been fortuitous, the possibility exists that in cases of unilateral hydrosalpinx, the performance of salpingectomy may improve fecundity without the need for IVF. Hopefully the outcome of these 2 case reports may generate interest in a larger cooperative prospective study. copyright copyright 1999 S.

3/19. salpingectomy improves outcome in the presence of a unilateral hydrosalpinx in a donor oocyte recipient: a case report.PURPOSE: To determine if unilateral salpingectomy for hydrosalpinx can improve fecundity in a woman with many cycles of failure to conceive despite the fertilization of donor oocytes and subsequent embryo transfer. methods: salpingectomy performed after failure to conceive despite IVF-ET with the patient's own oocytes (n=5) or transfer of donor embryos (n=2) or embryo transfer cycles as a donor oocyte recipient (n=5). RESULTS: The patient conceived three of four times following salpingectomy. Transfer of four frozen-thawed donor embryos and two frozen-thawed embryos of her own led to a successful delivery. In one of two cycles as a donor oocyte recipient she had a successful delivery and subsequently, the transfer of cryopreserved/thawed embryos from a previous donor oocyte cycle led to a chemical pregnancy. CONCLUSION: Unilateral hydrosalpinx can be a cause of recalcitrant failure to conceive despite assisted reproductive technology. salpingectomy can restore fecundity.- - - - - - - - - - ranking = 0.2keywords = fertilization (Clic here for more details about this article) |
4/19. Heterotopic pregnancy in a natural conception cycle presenting with tubal rupture: a case report and review of the literature.BACKGROUND: Heterotopic pregnancy is a potentially fatal condition, rarely occurring in natural conception cycles. CASE: We report such a case in a 28-year old para 0, gravida 1 woman with no known risk factors. The ectopic pregnancy was diagnosed after rupturing at 11 weeks, 4 weeks after diagnosis of the intrauterine pregnancy, and resected via laparotomy. A healthy baby was delivered without complications at 40 weeks gestation. CONCLUSION: Heterotopic pregnancy is possible with natural conception and the survival of the intrauterine fetus is feasible.- - - - - - - - - - ranking = 0.021757349188054keywords = conception (Clic here for more details about this article) |
5/19. peritonitis after a ruptured left pyosalpinx in a patient undergoing in vitro fertilization.OBJECTIVE: To report acute abdomen in a young woman with infertility due to small asymptomatic bilateral hydrosalpinges who was on the 12th day of an IVF cycle. DESIGN: Case report. SETTING: Private IVF clinic. PATIENT(S): A 35-year-old woman with asymptomatic bilateral hydrosalpinges. INTERVENTION(S): Abdominal laparoscopy. MAIN OUTCOME MEASURE(S): Pus and a ruptured left pyosalpinx. RESULTS: The patient suddenly developed acute abdomen while lifting a disabled person at a nursing home where she worked as a nurse. About 200 mL of pus was aspirated, and the patient had a ruptured left pyosalpinx. Bilateral salpingectomy was done by laparoscopy; the patient's postoperative recovery was uneventful. CONCLUSION: We report a rare case of acute abdomen due to peritonitis after a ruptured pyosalpinx in an IVF patient who lifted a disabled person.- - - - - - - - - - ranking = 0.8keywords = fertilization (Clic here for more details about this article) |
6/19. Ovarian pregnancy resulting from cornual fistulae in a woman who had undergone bilateral salpingectomy.OBJECTIVE: To report a case of ovarian pregnancy following in vitro fertilization-embryo transfer (IVF-ET) treatment for which the cornual fistulae was the most probable explanation of the cause. DESIGN: Case report. SETTING: University department and assisted reproduction unit. PATIENT(S): A 29-year-old woman with primary infertility. INTERVENTION(S): Hydrosalpinx of the bilateral fallopian tubes has been noted in patients who have decreased pregnancy rates in the IVF-ET treatment cycles. salpingectomy before IVF cycles has been suggested to increase the pregnancy rate. We report a patient who presented with bilateral hydrosalpinx for whom bilateral salpingectomy was performed before IVF treatment. MAIN OUTCOME MEASURE(S): Clinical pregnancy. RESULT(S): The treatment cycle resulted in a primary ovarian pregnancy and required laparoscopic operation. A cornual fistulae was found that have might led to ectopic implantation of the embryos. CONCLUSION(S): Ovarian pregnancy may be an unexpected complication of those receiving bilateral salpingectomy before IVF treatment. The presence of cornual fistulae after salpingectomy was probably the cause of the ectopic pregnancy.- - - - - - - - - - ranking = 0.2keywords = fertilization (Clic here for more details about this article) |
7/19. Ectopic pregnancy after luteal phase initiation of gonadotropin-releasing hormone analog before in vitro fertilization.Three patients had an undetected pregnancy when they commenced a GnRH-a on the 21st day of their cycle before ovulation stimulation for IVF. Two of the three pregnancies were later diagnosed as ectopic gestations. Based on this and previous case reports in the literature, it is suggested that luteal phase administration of GnRH-a may predispose to EPs, particularly in patients with damaged tubes, by reducing tubal motility secondary to a transient increase in circulating P concentrations.- - - - - - - - - - ranking = 0.8keywords = fertilization (Clic here for more details about this article) |
8/19. Ectopic pregnancy in a preexisting hydrosalpinx during a spontaneous pregnancy.OBJECTIVE: To discuss the possible role of abnormal embryo migration as a cause of ectopic pregnancy during IVF with hydrosalpinges. DESIGN: Case report. SETTING: University-based reproductive endocrinology and fertility clinic. PATIENT(S): A patient presenting with a tubal ectopic pregnancy after spontaneous conception in a preexisting hydrosalpinx. INTERVENTION(S): Laparoscopic salpingectomy. MAIN OUTCOME MEASURE(S): Ultrasound and operative findings. RESULT(S): Case demonstration of abnormal embryo migration into a surgically documented preexisting hydrosalpinx during a spontaneous conception. CONCLUSION(S): The mechanism of increased tubal ectopic pregnancy rates during IVF with hydrosalpinges remains unexplained. This case supports abnormal embryo migration due to the hydrosalpinx as a contributing factor.- - - - - - - - - - ranking = 0.0072524497293514keywords = conception (Clic here for more details about this article) |
9/19. The use of transvaginal ultrasound to aspirate bilateral hydrosalpinges prior to in vitro fertilization: a case report.Transvaginal ultrasound has recently been introduced diagnostically for follicular monitoring, early pregnancy localization (1), pelvic structure identification, early fetal development (2), detection of ovarian enlargement in postmenopausal women (3), and detection of endometrial carcinoma (4). Transvaginal ultrasound has had a major impact on patient monitoring and treatment for in vitro fertilization and embryo transfer (IVF/ET). Therapeutically transvaginal ultrasound has been introduced for oocyte retrieval and selective pregnancy reduction. The purpose of this paper is to present the therapeutic use of transvaginal ultrasound to aspirate large bilateral hydrosalpinges which complicated embryo transfer during an in vitro fertilization cycle.- - - - - - - - - - ranking = 1.2keywords = fertilization (Clic here for more details about this article) |
10/19. Ectopic pregnancies due to contralateral fistulas after sterilization by electrocoagulation; case reports.Three cases of post-sterilization tubal pregnancy are discussed. The sterilizations were performed by bipolar electrocoagulation. The location of the pregnancy was distal to the site of sterilization. There was no continuity between the segment containing the ectopic pregnancy and the uterus. spermatozoa reached the site of fertilization via a tuboperitoneal fistula. The existence of the fistulas was confirmed by a methylene blue test. In two cases fistulas existed on the contralateral side to the ectopic pregnancy. In the third case, bilateral fistulas were found. So, on performing a salpingectomy for ectopic pregnancy after sterilization failure, we have to be aware of contralateral fistulas. Also good understanding of the mechanism of extra-uterine pregnancy secondary to transperitoneal migration of spermatozoa is important when doing conservative tubal surgery.- - - - - - - - - - ranking = 0.2keywords = fertilization (Clic here for more details about this article) |
