risk factors and morbidity in patients with Placenta Previa accreta compared to Placenta Previa non accreta
Acta Obstetricia et Gynecologica Scandinavica, 1998Co-Authors: Zaki M. S. Zaki, Ahmed M. Bahar, Mohamed E. Ali, Hassan A. M. Albar, Mohamed A. GeraisAbstract:Background Placenta accreta is associated with high morbidity and most cases occur with Placenta Previa. This study was carried out in an attempt to define risk factors for Placenta accreta in cases of Placenta Previa and to quantify the increased morbidity of Placenta Previa accreta in comparison to Placenta Previa alone. Methods. The records of all patients delivered by cesarean section (CS) for Placenta Previa and accreta during the seven-year period from 1990 to 1996, inclusive, were reviewed. Data regarding the demographic features, previous CS, the incidence of hysterectomy and postpartum morbidity were analyzed. Results. Out of 23070 deliveries 110 (0.48%) had Placenta Previa, twelve (0.05%) of whom had Placenta Previa accreta. There was no significant difference in age and parity. Patients with a history of previous CS showed a significant increase in the incidence of Placenta Previa accreta (p=0.001). The percentage of accreta increased linearly from 4.1% in patients with no CS to 60% in patients who had had three or more CS. Postpartum hemorrhage and emergency hysterectomy were significantly higher among the Previa accreta patients compared with the Previa patients alone (p<0.001; p<0.001, respectively). Conclusion. In the presence of a previous history of CS, patients with antepartum diagnosis of Placenta Previa are considered to be at a greater risk for having Placenta accreta. The risk increases with the increase in the number of previous CS. Patients with Placenta Previa accreta have a significantly higher incidence of PPH and are more likely to undergo emergency hysterectomy.

Placenta Previa percreta with bladder invasion
Obstetrics & Gynecology, 1997Co-Authors: H Schapiro, J Broome, C E Welander, Ira M. BernsteinAbstract:Background : Although the clinical presentation and imaging techniques can raise suspicion for Placenta Previa percreta, this potentially catastrophic condition may remain undiagnosed or its extent underappreciated until delivery. The decision to proceed with definitive surgery in cases of Placenta Previa percreta should be carefully considered. Case : A case of Placenta Previa percreta with bladder invasion was diagnosed prenatally. This case illustrates the magnitude of complications that can arise despite aggressive multidisciplinary perioperative management. Conclusion : When possible, hysterectomy performed for Placenta Previa percreta is best avoided under anything other than ideal conditions. A multidisciplinary approach for preoperative, intraoperative, and postoperative management of Placenta Previa percreta optimizes maternal outcome.

The cervix as a natural tamponade in postpartum hemorrhage caused by Placenta Previa and Placenta Previa accreta: a prospective study.
BMC pregnancy and childbirth, 2015Co-Authors: Saad El Gelany, Ahmed R. Abdelraheim, Mo’men M. Mohammed, Mohammed T. Gad El-rab, Ayman M. Yousef, Emad M. Ibrahim, Eissa M. KhalifaAbstract:Placenta Previa and Placenta accreta carry significant maternal and fetal morbidity and mortality. Several techniques have been described in the literature for controlling massive bleeding associated with Placenta Previa cesarean sections. The objective of this study was to evaluate the efficacy and safety of the use of the cervix as a natural tamponade in controlling postpartum hemorrhage caused by Placenta Previa and Placenta Previa accreta. This prospective study was conducted on 40 pregnant women admitted to our hospital between June 2012 and November 2014. All participating women had one or more previous cesarean deliveries and were diagnosed with Placenta Previa and/or Placenta Previa accreta. Significant bleeding from the Placental bed during cesarean section was managed by inverting the cervix into the uterine cavity and suturing the anterior and/or the posterior cervical lips into the anterior and/or posterior walls of the lower uterine segment. The technique of cervical inversion described above was successful in stopping the bleeding in 38 out of 40 patients; yielding a success rate of 95 %. We resorted to hysterectomy in only two cases (5 %). The mean intra-operative blood loss was 1572.5 mL, and the mean number of blood units transfused was 3.1. The mean time needed to perform the technique was 5.4 ± 0.6 min. The complications encountered were as follows: bladder injury in the two patients who underwent hysterectomy and wound infection in one patient. Postoperative fever that responded to antibiotics occurred in 1 patient. The mean duration of the postoperative hospital stay was 3.5 days This technique of using the cervix as a natural tamponade appears to be safe, simple, time-saving and potentially effective method for controlling the severe postpartum hemorrhage (PPH) caused by Placenta Previa/Placenta Previa accreta. This technique deserves to be one of the tools in the hands of obstetricians who face the life-threatening hemorrhage of Placenta accreta. ClinicalTrials.gov NCT02590484 . Registered 28 October 2015

Applicability of ultrasonography for detection of marginal sinus Placenta Previa.
Medicine, 2021Co-Authors: Hiroki Ishibashi, Morikazu Miyamoto, Hiroshi Shinmoto, Shigeyoshi Soga, Hideki Iwahashi, Soichiro Kakimoto, Hiroko Matsuura, Takahiro Sakamoto, Taira Hada, Rie SuzukiAbstract:ABSTRACT This study aimed to examine whether marginal sinus Placenta Previa, defined as when the marginal sinus just reaches the internal cervical os and Placental parenchyma might be >2 cm from the internal cervical os, can be diagnosed using ultrasonography (US). We identified the Placenta Previa cases that underwent both US and magnetic resonance imaging (MRI) between April 2010 and December 2018 at our institution. The diagnostic discrepancies for marginal sinus Placenta Previa between US and MRI were examined retrospectively. Of the 183 cases of Placenta Previa, 28 (15.3%) cases were diagnosed as marginal sinus Placenta Previa using MRI. Among them, 18 cases (64.3%) could also be diagnosed using US. The sensitivity and specificity of the diagnosis of marginal sinus Placenta Previa using US were 64.3% and 92.9%, respectively. A change in US diagnosis occurred in 10 (35.7%) cases, all of which were diagnosed with low-lying Placenta Previa or marginal Placenta Previa and did not develop any serious miserable obstetrical outcomes. In conclusion, the diagnostic accuracy of US for detecting marginal sinus Placenta Previa was not significant. MRI examination may be required to accurately categorize the types of Placenta Previa.
