Pathological study of Placenta Samples Sent to the Department of Pathology in Shahid Sadoughi Hospital from 2009 to 2016

Introduction: Placenta disorders are the most prevalent and the most serious complications of pregnancy in human beings. In the current study, pathological analysis of placental samples sent to the department of pathology from 2009 to 2016 was done. Methods: The present study is a cross-sectional study on placenta samples sent to the department of pathology taking a census. Age and number of pregnancies, microscopic and macroscopic findings of placenta and umbilical cord, placental length, placental width, placental thickness, placental weight, the length of umbilical cord and the thickness of umbilical cord were recorded. The data were collected by a checklist and were entered in SPSS version 17. Findings: The results also showed that there was a significant statistical difference between microscopic findings of placenta and age and also between microscopic and macroscopic findings of placenta and the number of pregnancies (P-value 0.05). Conclusion: Since there is a meaningful statistical relationship between placental microscopic findings and age, and between placental microscopic and macroscopic findings and the number pregnancy, it can be concluded that age increasing and number of pregnancy are two main factors associated with an increase in the risk of placental changes.
