ABSTRACT
Objective:To investigate the diagnosis and management of partial or complete hydatidiform mole with coexistent intrauterine pregnancy.Methods:Clinical data of 10 cases of hydatidiform mole with coexistent intrauterine pregnancy admitted to the Third Affiliated Hospital of Guangzhou Medical University, from September 2009 to May 2019 were retrospectively described.Results:(1) During the same period, 65 960 women were delivered at our hospital, and hydatidiform mole with coexistent intrauterine pregnancy was accounted for 1/6 596, among which complete hydatidiform mole and coexisting fetus (CHMCF) and partial hydatidiform mole and coexistent fetus (PHMCF) were found in four and six cases, respectively. The mean age of the ten patients were (30.9±4.1) years old, ranging from 26 to 35 years old, with 2.5 (1-4) times of pregnancies. Nine cases were identified at 22 +3 (12 +3-32 +3) gestational weeks and one at 9 + weeks. (2) Recurrent vaginal bleeding during pregnancy occurred in six cases, nausea and vomiting in three cases, and hyperthyroidism in mid- and late pregnancy in two cases. One patient developed preeclampsia and one case of severe mitral regurgitation with mild pulmonary hypertension. (3) In the 10 patients, the summit serum β -hCG level was 139 935 (16 990-546 033) U/L, and CHMCF and PHMCF patients were 212 500 (200 000-546 033) U/L and 60 768 (16 990-225 000) U/L, respectively. (4) The ultrasound results revealed a dark honeycomb area of the placenta in five cases, placental thickening in two cases, and vesicular placenta in one case. One case was found with bilateral giant luteinized ovarian cyst by ultrasound, multiple metastases in the left lower lobe of the lung by chest CT, multiple nodules in the pleural wall of the left lung by lung MRI, and CHMCF by pelvic MRI. In one case, ultrasound at 14 weeks of gestation showed interrupted fetal abdominal wall, visible mass, gastric bubble, liver, part of the intestinal echoes, and omphalocele. One case was found with embryo arrest. (5) The karyotype analysis of one case through amniocentesis was 46,XX with no anomalies, and chromosome microarray analysis was arr[hg19](1-22)×2. Prenatal diagnosis was refused in the remaining cases. (6) Among the ten patients, three were terminated by rivanol intra-amniotic injection, two received drug abortion, and uterine evacuation, and two with spontaneous abortion followed by curettage with a visible fetus and hydatidiform tissue. Total hysterectomy was performed in one patient due to partial invasion of the uterus by hydatidiform mole. One patient underwent a cesarean section on account of the left lower lung metastasis. One case developed preeclampsia at 33 +4 weeks of gestation and delivered two premature infants by cesarean section. Pathology examination found a complete and partial vesicular fetal mass in four and six cases, with P57 (－) and P57 (+), respectively. (7) During the follow-up, two women developed the persistent trophoblastic disease and received chemotherapy, while the remaining eight cases did not. Conclusions:When hydatidiform mole with coexistent intrauterine pregnancy is found, a timely differential diagnosis between CHMCF and PHMCF is needed. CHMCF is at a higher risk of abortion, intrauterine death, premature delivery, preeclampsia, and other maternal complications. Therefore, termination of CHMCF should be individualized. Most PHMCF patients have fetal malformation or fetal loss; thereby, timely termination is recommended.
ABSTRACT
Objective:To investigate the appropriate method of labor induction in the second trimester for complete placenta previa patients.Methods:The labor induction outcomes of 85 cases with complete placenta previa in the second trimester were retrospectively analyzed. Twenty patients in group A were treated with cesarean section, 30 patients in group B were treated with ethacridine and mifepristone combined with uterine artery embolization (UAE), and 35 patients in group C were induced by using ethacridine and mifepristone. The clinical features and induction outcomes of three groups were compared.Results:The total duration of labor in group B [(28.7±30.1) hours] was significantly longer than that of group C [(24.3±21.9) hours; P<0.05]. The total amount of blood loss during induction and labor in group B [(302±271) ml] was significantly lower than those of group C [(393±523) ml] and group A [(626±487) ml; P<0.05]. The incidence of fever in group B (13%, 4/30) was significantly higher than those of group C (11%, 4/35) and group A (10%, 2/20; P<0.05). In group C, 13 patients (37%, 13/35) underwent emergency UAE, and 2 patients (6%, 2/35) underwent emergency cesarean section. As to average hemoglobin level and blood transfusion rate, there were no difference among the three groups (all P>0.05). Conclusion:Prophylactic UAE combined with drug induction in patients with complete placenta previa in the second trimester could significantly reduce the amount of bleeding during induction and reduce the risk of emergency procedures.
ABSTRACT
Objective To study the feasibility and safety of trial of labor after cesarean section (TOLAC). Methods Retrospective analysis of five medical center of Guangdong province from January 2011 to December 2015 hospitalized delivery information, compare the same scar TOLAC (research group) with the scar pregnancy (control group) pregnancy outcomes, to study the feasibility and safety of TOLAC. Results (1)During 2011-2015, total delivery 95 600 cases in five medical center, 13 824 cases of thme with uterine scar pregnancy, including 12 027 cases elective repeat cesarean section and 1 797 cases (13.00%, 1 797/13 824) with scar uterus vaginal trial of labor. Among 1 308 cases of vaginal delivery,the success for trial of labor rate was 72.79% (1 308/1 797). From 2011 to 2015, there were increased rate of pregnancy after cesarean section, which were respectively 10.71%, 13.28%, 14.45%, 15.54%and 16.98%. The will of vaginal birth were rising and the rate were respectively 11.85%, 12.25%, 13.49%, 13.82%and 12.93%. (2) There were 489(27.21%,489/1 797) cases of scar uterus maternal emergency cesarean section in the trial of labor, reason for“social factors”require for cesarean delivery have 68 cases, the percentage was 13.91% (68/489), compared with control group (7.18%, 206/2 869), the difference was statistically significant difference (χ2=27.356,P=0.000). Doctors diagnosed as“aura uterine rupture”in the labor was 11.86% (58/489), compared with that in control group (1.43%, 41/2 869), the differences were statistically significant difference (χ2=1 578.223,P=0.000). (3) The incidence of uterine rupture of the research group(0.74%,9/1 211)was significantly higher than that of control group (0.01%,2/31 200;χ2>2 000,P=0.000). The incidence of postpartum hemorrhage in research group was 6.94% (84/1 211), compared with that in the control group (3.05%, 951/31 200), there was statistically significant difference (χ2=16.328,P=0.000). While, there were no statistical significancefor the labor time limit,birth rate of severe asphyxia and neonatal birth weight average differences between two groups (P>0.05). Conclusions The rate of pregnancy after cesarean section is increasing year by year, and the will of vaginal birth is increasing, while it still are generally low. TOLAC is safe and feasible, but also significantly higher risk, strictly labor monitoring and can proceed fast cesarean delivery in delivery room is an important guarantee of safe delivery.
