1/490. Crack-cocaine-associated aortic dissection in early pregnancy--a case report.Even though uncommon in pregnancy, aortic dissection is a potentially catastrophic vascular complication, occurring mainly in the late stages of pregnancy. Vascular events, including aortic dissection are recognized complications of crack-cocaine use. The authors report a case of aortic dissection in early pregnancy related to crack-cocaine use. They believe that the combined effects of pregnancy and crack cocaine on the vasculature create the requisite milieu potentiating such catastrophic events as aortic dissection. This paper reviews the possible underlying pathophysiologic mechanisms and the available diagnostic, therapeutic, and management options.- - - - - - - - - - ranking = 1keywords = pregnancy (Clic here for more details about this article) |
2/490. uterine artery embolization--a successful treatment to control bleeding cervical pregnancy with a simultaneous intrauterine gestation.A case of a woman suffering from a bleeding heterotopic cervical pregnancy is described. The concurrent cervical pregnancy and intrauterine gestation were diagnosed by ultrasound and bleeding was initially controlled with selective fluoroscopic uterine artery embolization. A selective fetal reduction was done with ultrasound-guided intracardiac potassium chloride. uterine artery embolization has been used successfully to control haemorrhage in cervical pregnancies when the main goal was to allow preservation of the uterus, thus maintaining potential fertility. This is the first report of arterial embolization used to control bleeding for maintaining a concurrent intrauterine heterotopic pregnancy in an in-vitro fertilization patient. Unfortunately, subsequent conservative measures led to undesired outcome. This procedure initially controlled the bleeding without disrupting the intrauterine fetal cardiac activity.- - - - - - - - - - ranking = 0.875keywords = pregnancy (Clic here for more details about this article) |
3/490. Early prenatal diagnosis of cord entanglement in monoamniotic multiple pregnancies.OBJECTIVES: Cord entanglement is a severe complication in monoamniotic multiple pregnancies. Three cases were reviewed to determine how early ultrasound diagnosis might improve counselling and management. methods: In two monoamniotic twin and one dichorionic diamniotic triplet pregnancies, cord entanglement was detected between 10 and 18 gestational weeks by color Doppler and pulsed Doppler velocimetry. Pregnancies were followed up on a weekly basis with special observation of fetal behavior and use of color Doppler velocimetry. RESULTS: In Case 1, a monoamniotic twin pregnancy with cord entanglement close to the umbilical insertions was diagnosed at 10 weeks. Longitudinal follow-up showed intrauterine death of both twins at 15 weeks. In Case 2, entanglement of the umbilical cords of two monoamniotic triplets within a dichorionic diamniotic triplet pregnancy was diagnosed at 10 weeks. The pregnancy continued uneventfully until 35 weeks when cord entanglement was confirmed at cesarean section. All triplets have since developed normally. In Case 3, monoamniotic twins were diagnosed at 18 weeks. color Doppler detected side-by-side insertion of the umbilical cords and Doppler velocimetry suggested an entanglement at the chorionic plate. The pregnancy was complicated by polyhydramnios. cesarean section at 36 weeks confirmed cord entanglement at the chorionic plate. Postnatal computer angiography and morphological examination of the placenta showed the presence of superficial artery-to-artery and vein-to-vein anastomoses and of deep arteriovenous shunts. The development of the twins was uneventful. CONCLUSIONS: Diagnosis of cord entanglement is feasible early in gestation. Future protocols are proposed to document the gestational age at detection, the location, and the Doppler flow patterns and to facilitate the assessment of short- and long-term development.- - - - - - - - - - ranking = 0.5keywords = pregnancy (Clic here for more details about this article) |
4/490. Prenatal sonographic features of embryonal rhabdomyosarcoma.We describe a case of fetal rhabdomyosarcoma detected during the third trimester of pregnancy by prenatal sonography. At 33 weeks' gestation, sonography performed because of suspected polyhydramnios showed a solid mass of 120 x 54 mm arising from the anterior wall of the fetal thoracic cage. Another mass within the left maxillary area which originated from the left orbital floor was also detected. In the abdomen, there were multiple round masses in and around the liver. As the previous scan at 28 weeks had appeared normal, the multiple masses which became visible and enlarged rapidly in different locations led us to believe that there was fetal cancer. The most likely diagnosis was rhabdomyosarcoma (which was later confirmed), because it is the most prevalent soft-tissue tumor in children and may develop within or outside muscle anywhere in the body and at any age. Two other reported cases which were detected by prenatal ultrasound examination are also discussed.- - - - - - - - - - ranking = 0.125keywords = pregnancy (Clic here for more details about this article) |
5/490. Massive rectal bleeding due to jejunal and colonic tuberculosis.A case of massive rectal bleeding due to colonic tuberculosis in advanced pregnancy with intrauterine foetal death is reported. Patient was treated with resection of the left colon and left transverse end colostomy with closure of the rectal stump. hysterotomy for the removal of the dead foetus was performed. The patient improved in health with antitubercular treatment. The colorectal anastomosis was performed after 4 months. Massive rectal bleeding in intestinal tuberculosis, though rare should be kept in mind.- - - - - - - - - - ranking = 0.125keywords = pregnancy (Clic here for more details about this article) |
6/490. Infiltration block for caesarean section in a morbidly obese parturient.We report a case of a morbidly obese parturient (150 kg and 150 cm) for emergency lower segment caesarean section for dead foetus. Her pregnancy had been unsupervised. She presented with severe pre-eclampsia, generalized oedema and acute respiratory failure. Caesarean section was performed under infiltration block using lidocaine 0.5-1.0%. Her status improved postoperatively with aggressive physiotherapy, nursing in a semirecumbent position and oxygen supplementation.- - - - - - - - - - ranking = 0.125keywords = pregnancy (Clic here for more details about this article) |
7/490. Rapid development of hydrops fetalis in the donor twin following death of the recipient twin in twin-twin transfusion syndrome.Intrauterine death of one fetus in monochorionic twinning is associated with high rates of perinatal morbidity and mortality in the surviving fetus. Subsequent development of hydrops fetalis in the donor twin after fetal demise of the recipient twin has been described in only two case reports and pathophysiology remains unclear. We report on a monochorionic-diamniotic twin pregnancy complicated by severe twin-twin transfusion syndrome. Ultrasound examination at 20 weeks of gestation showed discrepant twins with oligohydramnios in the smaller twins' sac and polyhydramnios in that of the larger twin. Repeated amniocenteses permitted prolongation of the pregnancy. However, the recipient twin developed deteriorating hydrops fetalis and died at 28 weeks of gestation. After this event, subsequent development of hydrops fetalis in the surviving donor twin could be observed, as well as an increase of amniotic fluid. An elective cesarean section was performed at 29 weeks of gestation. Initial hypoxemia could be effectively treated by high frequency oscillatory ventilation, surfactant therapy and inotropic support. The infant was discharged in good condition at the age of 2 months. Although rare, antenatal demise of the recipient twin in a monochorionic pregnancy can be associated with the subsequent development of hydrops fetalis in the surviving donor twin. We speculate that this phenomenon is due to ischemia-reperfusion injury of the previously poorly perfused twin.- - - - - - - - - - ranking = 0.375keywords = pregnancy (Clic here for more details about this article) |
8/490. Acute onset of dermatomyositis presenting in pregnancy with rhabdomyolysis and fetal loss.We report a case of acute onset of dermatomyositis with rhabdomyolysis and myoglobinuria, which presented in the 14th week of pregnancy and resulted in spontaneous abortion of the fetus. The diagnostic work up for an underlying disease was negative and the histologic examination confirmed the diagnosis of dermatomyositis, which subsequently improved with corticosteroids.- - - - - - - - - - ranking = 0.625keywords = pregnancy (Clic here for more details about this article) |
9/490. Maternal uniparental isodisomy for chromosome 14 detected prenatally.Maternal uniparental disomy (UPD) for chromosome 14 (upd(14)mat) has been associated with a distinct phenotype. We describe the first case of maternal uniparental isodisomy for chromosome 14 detected prenatally, in a pregnancy with mosaicism for trisomy 14 observed in both a chorionic villus sample (CVS) and in amniocytes. Detailed analysis of polymorphic microsatellites showed that the fetus was essentially isodisomic for one of the mother's chromosomes 14 and that recombination had introduced a mid-long arm region of heterodisomy. The fetus, which died in utero at 18 weeks, showed no apparent pathological features. The case demonstrates for the first time a maternal meiosis II non-disjunction of chromosome 14 leading to a trisomic conception which has been incompletely corrected by 'rescue' in the early embryo.- - - - - - - - - - ranking = 0.125keywords = pregnancy (Clic here for more details about this article) |
10/490. Abdominal pregnancy in a 67-year-old woman undetected for 37 years. A case report.BACKGROUND: Abdominal pregnancy is an exceedingly rare occurrence, but even more unusual is prolonged retention of an advanced abdominal pregnancy with lithopedion formation. We present the case of prolonged retention of an advanced abdominal pregnancy in an elderly women. CASE: A 67-year-old, white woman presented to the emergency department with abdominal pain. An acute abdominal series revealed a fetal skeleton extending from the patient's pelvis to her lower costal margins. Pelvic examination revealed a normal postmenopausal uterus, and human chorionic gonadotropin was negative. On further questioning the patient reported that she had become pregnant 37 years earlier and was diagnosed as having a "missed" pregnancy. She refused intervention at that time but suffered no untoward consequences. She reported having had later a healthy intrauterine pregnancy, delivered vaginally at term. No attempt was made to remove the prior missed abdominal pregnancy. The acute pain episode resolved, and there was no surgical intervention. CONCLUSION: Abdominal pregnancies can have a complex course, and management decisions can be difficult. This case presents an unusual outcome of an advanced abdominal pregnancy and illustrates a unique approach to management.- - - - - - - - - - ranking = 1.375keywords = pregnancy (Clic here for more details about this article) |
