Methods: This was a retrospective study of women under cesarean delivery with PAS or placenta previa. Patients’ information was acquired from hospital records. A novel procedure of surgery is developed with seven major steps, including avoiding placenta incised, elevating upward the uterine, clamping the uterine arteries with sponge forceps, removing the placenta, opening the vesicouterine space and suture techniques. Results: A total of 38 patients were reviewed. Twenty-one patients diagnosed with placenta accrete syndrome and 3 patients with CSP were underwent surgery with the novel procedure of surgery and all severe hemorrhage was controlled without hysterectomy. There were 2 women with bladder injuries needing primary repair. Fourteen patients with placenta previa underwent cesarean delivery and there was no intraoperative complication of the total 14 patients. Conclusion: The seven-step approach is more secure and effective to control severe hemorrhage without other invasive procedures in cesarean delivery with PAS. It is technically easier to maintain and improve surgical skills.展开更多

Study Design: ...Objective: To evaluate the effectiveness of conservative compression surgical suture techniques used for the management of pernicious placenta previa to conserve fertility in the subsequent pregnancies. Study Design: This was a non-comparative retrospective study of 188 patients diagnosed with pernicious placenta previa who underwent cesarean section in The First Hospital of Jilin University, China, from 1 January 2013 to 1 January 2018. Successful group was defined as those in which the intraoperative bleeding was managed by either modified CHO or by B-lynch suture technique and those who had further intervention including hysterectomy were designated as failure group. Results: Out of 217 patients, 188 met inclusion criteria and 29 patients were excluded. In 188 cases, 183 (97.34%) cases successes and 5 (2.65%) cases had hysterectomy. Among included group, 118 patients (62.76%) had undergone emergency cesarean section and 70 patients (37.23%) underwent elective cesarean section. The emergency group had significantly lesser gestation period of gestation at the time of cesarean section (P = 0.021) and lower neonatal weight (P = 0.001) than that of elective group. The estimated blood loss during surgery was 500 - 3200 ml (mean: 925 ml). Additionally, the amount of bleeding was found to be significantly more in patient with intraoperative complication (P = 0.007) and in patient with implanted placenta (P 0.001). Conclusion: The conservative compression suture technique including modified CHO and B-lynch suture technique during the cesarean delivery is a feasible, safe and effective alternative conservative surgical technique for the management of bleeding in case of pernicious placenta previa. Besides good surgical outcome and proper neonatal result this technique also reduces the rate of hysterectomy, thus conserving the fertility.展开更多

The incidence has increased. Diagnosis before delivery allows multidisciplinary planning in an attempt to minimize potential maternal or neonatal morbidity and mortality. Prenatal ultrasonography is used to support the diagnosis and guide clinical management leading probably to favorable outcomes. Actually a conservative option which includes leaving all or part of the placenta in situ when fertility preservation is desired is recommended. Methods: We retrospectively reviewed the medical records of all patients diagnosed with placenta accreta in gynecology-obstetrics department of the university hospital Mohammed the VI of Marrakesh;Morocco;from January the first 2014 to January the second 2016. Results: We found seven cases. We described: The epidemiological characteristics, risk factors, management of placenta accreta, outcomes and prognosis. The incidence of placenta accreta was 1/3847 deliveries. The mean term of delivery was 35 weeks. We have adopted a successful conservative treatment in six cases (71.4%). The radical treatment was adopted in one patient initially admitted for severe post-partum hemorrhage;the prognosis was good in 85.7% cases. Conclusion: Conservative management of placenta accreta is a safe and efficient and is an interesting alternative for hysterectomy.展开更多

This study was conducted to investigate how much abnormal placentation can affect blood bank capacity and to measure the burden on the blood bank caused by excessive use of blood and blood products. Methodology: This is a retrospective study conducted at King Saud Medical City Maternity Hospital in Riyadh, Kingdom of Saudi Arabia, from January 2019-September 2020. It includes 170 cases diagnosed with abnormal placentation (low-lying placenta or placenta previa, accreta, increta, or percreta). The primary purpose was to measure consumption of blood and blood products in cases of placental abnormalities and to investigate how much this affects blood bank capacity. A secondary aim was to report rates of admission to the ICU and maternal mortality. Results: This study included 170 women with placental abnormalities. Placental previa had occurred in 96 cases, followed by placenta accreta in 46 cases, placenta increta in 13 cases, placenta percreta in 8 cases, and low-lying placenta in 7 cases. Most patients (93) were treated with a Bakri balloon to prevent hemorrhage, but 38 patients had a hysterectomy. The average estimation of blood loss was 2210 ml, with no maternal mortality. An average of 3.39 units of packed red blood cells (PRBC) with a maximum of 20 units, 2.12 units of fresh frozen plasma (FFP) with a maximum of 20 units, and 0.7 units of packed platelets (PP) with maximum of 12 units consumed per patient. Eighty-seven patients (51.2%) were admitted to the ICU and 83 others (48.8%) were admitted to the high dependency unit. Conclusion:<span style="font-family: "> Blood and blood product volumes had a linear relationship with the severity of placental abnormalities and estimated blood loss. Therefore, blood bank services should be available to save mothers’ life.展开更多
