Diagnostic Performance of Ultrasonography for Detection of Abruption and Its Clinical Correlation and Maternal and Fetal Outcome

Abstract

Placental abruption complicates about 1% of singleton pregnancies and is an important cause of perinatal mortality and morbidity. Though sensitivity and reliability of ultrasound are poor for detecting or excluding placental abruption, because of the advances in ultrasound resolution, imaging and interpretation, sensitivity of ultrasound is better than what was reported previously. To determine the diagnostic performance of Aim: Ultrasonography (USG) for the detection of placental abruption and whether sonographic results correlate with maternal and foetal management and outcome Sixty patients with clinical diagnosis of placental abruption we Materials and Methods: re studied in the Obstetrics and Gynaecology Department of Gujarat Adani Institute of Medical Sciences, Bhuj over a period of 6 months. These patients underwent ultrasonography for conrmation. Obstetric and neonatal outcome and sonographic results were compared and reviewed. Sonographic sensitivity and specicity and positive and negative predictive values were calculated. Incidence of abruption in present study was 3.05% (56 Results: patients out of 1834 total deliveries). Sensitivity of ultrasonography in the diagnosis of abruption was 57% while its specicity was 100% with a positive predictive value of 100% and a 14% negative predictive value. An 87.5% of patients(28 out of 32) with a positive USG nding of abruption had Intrauterine foetal Death (IUD)/still birth while 91.6% of patients (22 out of 24) with negative USG ndings of abruption gave birth to babies who required NICU admission. Sonography has a poor sensitivity for diagnosing placental abrupt Conclusion: ion, even though it has a high specicity and PPV. In a positive sonographic result, maternal morbidity and perinatal mortality are high which needs aggressive obstetric management as compared to the normal sonography. In case of a negative sonographic nding but a strong clinical suspicion of abruption if Obstetric intervention is made in due time, foetal as well as maternal outcome are better
