Abstract
Trauma is the leading non-obstetric cause of death during pregnancy and approximately 6-8% of all pregnancies are complicated by injury, both accidental and intentional. The initial evaluation and management of the injured pregnant patient often requires a multidisciplinary, collaborative team to provide the optimal outcome for both mother and fetus. It is important to recognize that even minor mechanisms of injury may result in poor outcomes for both fetus and mother. Injured pregnant patients meeting admission criteria experience a progressive increase in the number of complications as well as the number of patients that require delivery. There exists opportunity to identify patients who require admission and provide supportive measures that may reduce the complications of prematurity. Patients that are admitted may benefit from a multidisciplinary approach including on-going care from obstetricians or maternal-fetal medicine physicians. Placental abruption is the most common pregnancy complication, and may occur with even minor mechanisms of injury. Increasing severity of trauma increases the frequency of abruption, admission, delivery, and fetal demise.

Abstract
BACKGROUND Computed tomography (CT) has been validated to identify and classify placental abruption following blunt trauma. The purpose of this study was to demonstrate improvement in fetal survival when delivery occurs by protocol at the first sign of class III fetal heart rate tracing in pregnant trauma patients with a viable fetus on arrival and CT evidence of placental perfusion 50% or less secondary to placental abruption. METHODS This is a retrospective review of pregnant trauma patients at 26 weeks' gestation or greater who underwent abdominopelvic CT as part of their initial evaluation. Charts were reviewed for CT interpretation of placental pathology with classification of placental abruption based upon enhancement (Grade 1, >50% perfusion; Grade 2, 25%-50% perfusion; Grade 3, <25% perfusion), as well as need for delivery and fetal outcomes. RESULTS Forty-one patients met inclusion criteria. Computed tomography revealed evidence of placental abruption in six patients (15%): Grade 1, one patient, Grade 2, one patient, and Grade 3, four patients. Gestational ages ranged from 26 to 39 weeks. All patients with placental abruption of Grade 2 or greater developed concerning fetal heart tracings and underwent delivery emergently at first sign. Abruption was confirmed intraoperatively in all cases. Each birth was viable, and Apgar scores at 10 minutes were greater than 7 in 80% of infants, all of whom were ultimately discharged home. The remaining infant was transferred to an outside facility. CONCLUSIONS Delivery at first sign of nonreassuring fetal heart rate tracings in pregnant trauma patients (third trimester) with placental abruption of Grade 2 or greater can lead to improved fetal outcome. LEVEL OF EVIDENCE Therapeutic/care management study, level III.

Abstract
OBJECTIVES To evaluate detection of post-traumatic placental abruption with contrast-enhanced CT (CECT) and comparison with Ultrasound (US). METHODS Picture Archive and Date System database at a level-1 trauma center was retrospectively reviewed using keywords pregnancy, trauma, and/or placental abruption over 10 years. CT was compared to US, if performed within 24 h. Two subspecialty-trained radiologists blindly reviewed the studies. Placental features on delivery and pregnancy outcomes were used as reference standard. Lack of adverse pregnancy/fetal outcome was treated as the absence of abruption. RESULTS CECT was performed in 36 patients, with 27 US within 24 h. There were three complete and eight partial abruptions. Reader sensitivity for CT was 100% for both reviewers; however, specificity was 54.5% and 56.7%. No sonographic abnormality was noted in both partial and complete abruption. Using kappa statistics, inter-observer agreement was low for both CT (0.169) and US (0.078). False-positive reads were from misinterpretation of normal placental structures like cotyledons, age-related infarcts, and marginal sinus of the placenta. CONCLUSIONS CECT identifies post-traumatic placental abruption with high sensitivity but low specificity for clinically significant abruptions, and performs better than US. Pitfalls from normal placental structures mimicking abruption should be avoided. US markedly underdiagnoses abruption.

Abstract
Modern military general surgeons tend to train and then practice in 'conventional' surgical specialties in their home nation; however, the reality of deployed surgical practice, either in a combat zone or on a humanitarian mission, is that they are likely to have to manage patients with a broad range of ages, conditions and pathologies. Obstetric complications of war injury include injury to the uterus and fetus as well as the mother and both placental abruption and uterine rupture are complications that military surgeons may have little experience of recognising and managing. On humanitarian deployments, fetomaternal complications are a common reason for surgical intervention. We report a recent patient's story to highlight the obstetric training needs of military surgeons.
