Aim Post‐partum hematomas are a serious obstetrical complication. Choosing treatments for post‐partum hematomas is difficult, and the application of transcatheter arterial embolization remains unclear. We aimed to clarify the clinical characteristics, identify the treatment indications and create a treatment algorithm for post‐partum hematomas. Methods Fifty‐four patients with post‐partum hematomas were enrolled. Hematomas were categorized according to location: upper vaginal, lower vaginal and vulvar. Blood loss, treatment methods and other clinical data were collected from the patients’ medical records and analyzed retrospectively. Results Five, 19 and 30 patients had upper vaginal wall, lower vaginal wall and vulvar hematomas, respectively. All upper vaginal wall hematomas required transcatheter arterial embolization to control bleeding, and the average blood loss was 2473 ± 1689 mL. Most lower vaginal wall hematomas were treated surgically; however, two patients required transcatheter arterial embolization, and the average blood loss in these patients was much higher (2010 ± 1145 mL) than that in patients with lower vaginal wall hematomas (395 ± 316 mL). No patient with vulvar hematomas was treated with transcatheter arterial embolization. Two and four patients with vulvar and lower vaginal wall hematomas, respectively, were managed with observation. Conclusion We created an algorithm for post‐partum hematoma management. Post‐partum hematoma location should guide treatment selection. Transcatheter arterial embolization should be selected for upper vaginal wall hematomas. Most lower vaginal wall hematomas are treatable with surgery, but transcatheter arterial embolization should be considered for hemostasis in difficult cases. Management with observation may also be possible for lower vaginal wall and vulvar hematomas.
Among blood parameters, higher D-dimer levels and lower levels of antithrombin activity and fibrinogen in late gestation were independent risk factors for PPH.
We here report the first case of discordant Pena-Shokeir phenotype observed in monoamniotic twins. A 34-year-old woman, pregnant with twins, was referred at 10 weeks' gestation because one of the twins had increased nuchal translucency. Serial ultrasonographic examinations suggested that twin A may have had several other abnormalities, including pleural effusion at 21 weeks' gestation, decreased movement and contracted limbs at 24 weeks, and fetal growth restriction at 26 weeks. No abnormalities were observed in twin B. At 34 weeks of gestation, the twins were delivered by cesarean section. There were cord entanglements, and although the resuscitation of twin A was attempted, it proved difficult due to lockjaw. Twin A died during the second hour of life, and autopsy findings were consistent with the diagnosis of Pena-Shokeir phenotype. We suggest that cord entanglement during early gestation is a possible cause for the occurrence of Pena-Shokeir phenotype through an anoxic-ischemic mechanism.
Aim Pulmonary embolism remains a leading cause of maternal mortality in developed countries despite developments in venous thromboembolism prophylaxis strategies. This study aimed to evaluate the effectiveness of our approach involving risk‐scoring, D‐dimer level assessment, and ultrasonography for obstetric venous thromboembolism. Methods This retrospective cohort study included women who delivered at 22–41 weeks of gestation in The University of Tsukuba Hospital, Japan between January and December 2020. Venous thromboembolism risk (determined according to Japanese guidelines) and D‐dimer levels were evaluated within 20 weeks of gestation, 30–34 weeks of gestation, and during the pre‐delivery period (36 weeks of gestation or any time before preterm delivery). Compression and color Doppler ultrasonography for lower extremity deep vein thrombosis were performed if D‐dimer levels were ≥3.2 μg/mL (for those undergoing cesarean delivery, 1.0 μg/mL). Results Of 1026 women, 6 women had deep vein thrombosis during pregnancy and 1 during the puerperium period. Pulmonary embolism was not observed. The D‐dimer screening result was positive for 8 women (2%) within 20 weeks of gestation (deep vein thrombosis was confirmed in 3 of them), 87 women (10%) (no deep vein thrombosis) at 30–34 weeks of gestation, and 367 women (36%) during the pre‐delivery period (asymptomatic deep vein thrombosis in one). Based on the Japanese guidelines, 1%, 11%, 33%, and 55% of women had high, intermediate, low, and no postpartum risk factors, respectively. Conclusions Our approach appears useful for antenatal venous thromboembolism screening in the first trimester. For postpartum prophylaxis, more cost‐effective strategies are needed.
The authors report the first case of prenatal fetal MRI diagnosis of unilateral hydrocolpos, uterus didelphys, and ipsilateral renal agenesis in a case of obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome. A 33-year-old woman was referred to the present institution because of a fetal pelvic cyst. Detailed ultrasound revealed a female fetus with a retrovesical cyst and right renal agenesis. Fetal MRI confirmed unilateral hydrocolpos, uterus didelphys, and normal intestinal tract of the fetus. Fetal MRI is a useful modality for prenatal diagnosis of OHVIRA as a method of evaluating the pelvic structures and excluding other cloacal anomalies.
