The main histopathologic diagnostic criteria for the identification of placenta accreta for quite 80 years has been the finding of a right away attachment of the villous tissue to the superficial smooth muscle or adjacent to myometrial fibers while not interposing epithelial tissue. There are only a few elaborate histopathologic studies in pregnancies sophisticated by placenta accreta spectrum disorders and our understanding of the pathophysiology of the condition remains restricted.

To prospectively appraise the microscopic changes employed in grading and to spot changes which may make a case for the abnormal placental tissue attachment.

A total of 40 consecutive cesarean section excision specimens for maternity accreta at 32 to 37 weeks of gestation with a minimum of 1 histological slide showing deeply deep-seated villi were analyzed. Prenatal ultrasound examination enclosed placental location, myometrial thickness, subplacental property and lacunae. Megascopic changes of the lower section were recorded throughout surgery and areas of abnormal placental adherence were sampled for microscopic anatomy. Additionally, 7 excision specimens with placenta unchanged from the Boyd assortment at20.5 to 32.5 weeks were used as controls [1].

Samples from accreta areas at delivery gift with a thick fibrinoid deposition at the utero-placental interface on microscopic examination severally of deeply deep-seated villous tissue within the sample. These changes are related to distortion of the Nitabuch membrane and would possibly make a case for the loss of components of the physiological website of detachment of the placenta from the female internal reproductive organ shut in placenta accreta spectrum [2]. These findings indicate that accreta placentation is quite direct attachment of the villous tissue to the superficial smooth muscle and support the construct that accreta villous tissue isn't really invasive.

When Irving and Hertig revealed the primary cohort on placenta accreta in 1937, they outlined the condition clinically because the abnormal adherence either in whole or partially of “the afterbirth” to the underlying female internal reproductive organ wall with placental villi directly hooked up to the smooth muscle beneath. They hypothesized that the pathologic basis for accreta placentation was the entire or partial absence of the epithelial tissue basalis permitting direct attachment of the villous tissue to the superficial smooth muscle. Only 1 of their patients had a history of cesarean section (CD) and therefore the main risk factors at the time were previous female internal reproductive organ curettement, manual placental removal and redness, which might all cause mucous membrane pathology and poor decidualization [3].

In 1966, Lukes et al introduced the construct of PAS to accommodate the various grades of adherence and invasion and steered that they'll be within the same specimen. There are few elaborate histopathologic series revealed since then, associated most pathologists have used and still use the initial finding of an absence of the epithelial tissue planned by Irving and Hertig because the main criterion for the identification of PAS. Similarly, authors of clinical studies don't offer complete info on each clinical and histopathologic finding at birth, or just check with Irving and Hertig definitions. Not amazingly, the according prevalence of PAS at delivery is very variable travel between 0.01% and 1%. Fewer than half the revealed clinical cohorts on prenatal identification, diagnostic procedure, diagnostic technique or management of PAS lack histopathologic confirmation of the diagnosis and grading so, our understanding of the pathophysiology of the various grades of PAS remains restricted [4].

This is a prospective study of 40 consecutive cases of elective CD excision for maternity accreta at 32 to 37 weeks of gestation with a minimum of one histological slide showing deeply deep-seated villi (increta). All patients conferred with a singleton gestation and a history of ≥2 previous CDs and ultrasound signs of PAS between March 20, 2019, and Dec15, 2020, at the Department of medical specialty and gynecology, University of Cairo, Cairo, Egypt. Institutional Scientific and analysis moral Committee approval (RSEC 021001) was obtained before the beginning of the study and consent was obtained from all patients for the employment of the photographic pictures obtained before and through the delivery [5].

StatGraphics and version 3 (Manugistics, Rockville, MD) information analysis and applied math computer code package was accustomed analyze the information. A standard Kurtosis analysis indicated some values weren't ordinarily distributed thus the and also the} data are therefore conferred as median and interquartile range (IQR). The data were separated into subgroups per the dimensions of the accreta area. Categorical variables were compared victimisation the Pearson chi-square check. A P value <.05 was considered significant.
