ABSTRACT
Objective: The aim of this study was to investigate the relationship between cervical length and risk for massive hemorrhage in placenta previa and determine whether a short cervix can be used as a predictor.
Study Design: A prospective cohort study.
Place and Duration of Study: This study was conducted at the Obstet & Gynae Department, Saidu Group of Teaching Hospital, Swat from 15th, January 2020 to 14th December 2023.
Methods: A total of 200 pregnant women in their third trimester diagnosed by Radiologist as placenta previa from the ages between20 and 36 weeks. Using trans-vaginal ultrasound of the cervix, cervical length was assessed, and patients were categorized as having a short cervix (Cervical Length ≤25 mm) or those with normal cervical length (> 25mm). The primary endpoint was the occurrence of massive bleeding (over 1000 mL blood loss and which need blood transfusion during caserean section). Secondary outcomes were maternal and neonatal morbidity.
Results: The study included 200 pregnant women diagnosed with placenta previa, divided into two groups according to cervical length; short cervix (≤ 25 mm) in group I; 80 women and 120 with a normal cervix (> 25 mm). Nevertheless, the group of short cervix versus that with normal one was delivered at a significantly earlier gestational age (35.9 ± 1.6 weeks vs. 36.5± 1.3 weeks; p = 0.04). a short cervix remained an independent predictor of massive hemorrhage (AOR 2.3; 95% CI: 1.4 - 3.8, p=0.01). Additional significant predictors were prior cesarean delivery (AOR 1.8; 95% CI: 1.1 - 3·0, p = 0.04) and complete previa (AOR.9; 95% CI 1.2 - 3.1, p = 0.03).
Conclusion: The significance of our study is in providing an understanding on the association between cervical length and hemorrhagic risk in placenta previa.
