conferenceObject Severe infections in pregnancy and the risk of venous thromboembolism (VTE)(2019) BARROS, V. V.; HASE, E. A.; HIGAI, A. M. K.; PEREIRA, P. P.; FRANCISCO, R. P. V.; ZUGAIB, M.- Live fetus inside the urinary bladder: a case report(2019) GOMEZ, Ursula Trovato; PEREIRA, Pedro Paulo; CABAR, Fabio Roberto; MESQUITA, Jose Luiz Borges de; FRANCISCO, Rossana Pulcineli VieiraVesicouterine fistula is a rare condition. Its incidence, however, has been increasing due to the higher incidence of cesarean sections. The presence of a live fetus inside the bladder who passed through a vesicouterine fistula is an extremely rare situation. We report a case of woman who underwent two previous cesarean sections, was referred to a hospital due to mild pelvic pain and genital bleeding. At the moment, physical examination was normal. Ultrasound scan revealed a gestational sac inserted into the anterior wall of the uterus, with a living fetus of approximately 13 weeks, with active body movement and normal heart rate inside it. The fetal abdomen, around the waist, was stuck at the opening of a vesicouterine fistula, so that the fetal head and trunk were entirely into the bladder cavity, while lower limbs remained at the uterine cavity. Laparotomy was performed, the fistulous tract was excised, the fetus (without heart beating) was removed on opening the bladder, and the uterine cavity was emptied. The defects in the bladder and uterus were repaired. The postoperative period was uneventful. A live fetus inside the urinary bladder is a rare condition the continuation of pregnancy is unlikely and the vesicouterine correction can be made by the time of surgical intervention.
- Pregnancy of unknown location(2019) PEREIRA, Pedro Paulo; CABAR, Fabio Roberto; GOMEZ, Ursula Trovato; FRANCISCO, Rossana Pulcineli VieiraPregnancy of unknown location is a situation in which a positive pregnancy test occurs, but a transvaginal ultrasound does not show intrauterine or ectopic gestation. One great concern of pregnancy of unknown location is that they are cases of ectopic pregnancy whose diagnosis might be postponed. Transvaginal ultrasound is able to identify an ectopic pregnancy with a sensitivity ranging from 87% to 94% and a specificity ranging from 94% to 99%. A patient with pregnancy of unknown location should be followed up until an outcome is obtained. The only valid biomarkers with clinical application and validation are serum levels of the beta fraction of hCG and progesterone. A single serum dosage of hCG is used only to determine whether the value obtained is above or below the discriminatory zone, that means the value of serum hCG above which an intrauterine gestational sac should be visible on ultrasound. Serum progesterone levels are a satisfactory marker of pregnancy viability, but they are unable to predict the location of a pregnancy of unknown location: levels below 5 ng/mL are associated with nonviable gestations, whereas levels above 20 ng/mL are correlated with viable intrauterine pregnancies. Most cases are low risk and can be monitored by expectant management with transvaginal ultrasound and serial serum hCG levels, in addition to the serum progesterone levels. To minimize diagnostic error and intervene during progressive intrauterine gestation, protocol indicates active treatment only in situations when progressive intrauterine pregnancy is excluded and a high possibility of ectopic pregnancy exists.
