[Acute traumatic thoracic aortic rupture in double localisation]. / Rupture aiguë post-traumatique de l'aorte thoracique en double foyer.

PURPOSE: Traumatic thoracic aortic rupture are commonly localised in one site essentially in the aortic isthmus but multiple localisation are not uncommon. The authors reported the case of a young man who had a double localisation of RTA after a violent car accident. CASE REPORT: A 23-year-old man had a violent car crush involving sudden deceleration. He had multiple injuries essentially: a traumatic thoracic injury with acute posttraumatic aortic rupture in double localization, in the isthmus and in the descending thoracic aorta. He underwent thoracic endovascular aortic repair (TEVAR) with the use of stent graft three weeks after his car accident. The endovascular treatment was successful and no case of perigraft leakage has been detected during a meaning follow-up of five months. CONCLUSION: The systematic analysis of the whole thoracic aortic vessel is crucial to not misdiagnose eventual multiple aortic rupture.

[Visual loss after spine surgery. Imaging findings]. / Cécité compliquant une chirurgie du rachis. Apport de l'imagerie.

Postoperative visual loss is a rare but disastrous complication that can be observed after spinal surgery. We report the case of a 39-year-old woman involved in a traffic accident that caused trauma to the cervical spine causing right hemiplegia, who underwent a prolonged spinal operation in the prone position and complained of monocular blindness 1 day postoperatively. The ophthalmologic examination showed no involvement of the ocular globe. The orbitocerebral MRI showed definite diagnostic arguments for orbital vascular injury. The symptoms did not completely disappear after 1 year of treatment. We consider the potential etiological factors contributing to this unilateral postoperative visual loss and suggest strategies to reduce the incidence of this complication in spinal surgery.

[Spinal vascular malformation in a child, revealed by lumbar puncture]. / Malformation vasculaire intraspinale chez l'enfant révélée dans les suites d'une ponction lombaire.

Spinal vascular malformations are exceptional in children. We report a case in 1 year-old patient due to a spinal vascular malformation which was revealed by paraplegia after lumbary punction. The diagnosis was made by MRI. Spontaneous outcome was characterised by the persistence of paraplegia.

[Fetal digestive tract pathology, imaging findings in antenatal diagnosis]. / La pathologie du tube digestif foetal, apport de l'imagerie dans le diagnostic anténatal.

Foetal anomalies of the digestive tract are numerous and dominated by malformations, the prognosis of which may be severe. Antenatal diagnosis of these anomalies allows a better management of neonates. It is known since about 20 years, a major development because of the progress realized in the field of foetal imaging. Ultrasonography, which is the best imaging modality, can be joined by MRI if necessary. The objective of this study is to evaluate the contribution of imaging in prenatal diagnosis of digestive anomalies, throughout a review of literature.
