Review
Most traumatic aortic injuries are the result of penetrating causes, whereas blunt aortic injury is less common. The initial treatment is determined by the patient's condition. Diagnostic studies include catheter arteriography, computed tomography, and transesophageal echo cardiography. This article summarizes the initial evaluation and management of patients with an aortic injury and describes the various treatment options such as delayed selective management, endovascular solutions, and surgical repair.

BACKGROUND
Traumatic injury to the descending thoracic aorta other than the isthmus is rare, and little known. Acute post-trauma rupture may occur in a context of multiple or rarely unique localizations.
CASE REPORT
We report the case of a young man who was the victim of multiple injuries with an isolated rupture of the descending thoracic aorta. Early diagnosis and adapted endovascular treatment led to favorable outcome.
CONCLUSION
In 90% of cases, acute post-trauma rupture of the aorta in a single localization involve the isthmus. Rupture of the descending aorta is more exceptional but must not be missed. The pathophysiological mechanism and appropriate management are discussed in light of a review of the literature.

Review
The development of MR angiography techniques has improved the quality of information available from MR of the thoracic aorta. With current cine techniques and three-dimensional MR angiography, the thoracic aorta can be examined noninvasively with a high degree of accuracy.

Review
This article addresses the history of blunt injury to the aorta by reviewing the epidemiology, military accounts, ancient history, and recent history during the last five decades of the twentieth century. Although they are a bit arbitrary and overlap somewhat, significant groupings regarding blunt injury to the thoracic aorta have occurred in ten-year blocks. It is important that any surgeon not be locked into a previous time period but be continually knowledgeable of ever-changing approaches. These approaches should always be based on the best evidence-based information available.

Understanding the mechanical environment of each component within the arterial wall is fundamental for understanding vascular growth and remodelling and for engineering artificial vascular conduits. We have investigated the mechanical status of arterial elastin by measuring the circumferential mechanical properties of purified elastin as function of position along the descending thoracic aorta of the pig. The tensile circumferential secant modulus, E(sec), measured in uniaxial mechanical tests, increased 30% (P<0.001), from a value of 0.88 MPa in the proximal tissue near the aortic arch to 1.14 MPa in the distal tissue near the diaphragm, indicating the stiffness of the elastin sample increased with position. Breaking stress was 54% higher in the distal tissue compared to the proximal (P<0.001), but the breaking stretch ratio did not change. E(sec) correlated with the ratio of radius to wall thickness measured in the no load state, r(nl)/h(nl), suggesting that the rise in stiffness was linked to ring morphology. The higher stiffness and strength of the distal tissue might be explained by a higher proportion of circumferentially oriented fibres in the distal tissue, which would indicate that the elastin meshwork in the thoracic aorta may become progressively anisotropic with distance from the heart. The ratio r(nl)/(h(nl)E (sec))rose only 7%, which suggests that the in vivo circumferential strain on the elastin may be constant along the pig thoracic aorta. The positional variation in elastin's properties should be taken into account in mechanical studies on purified elastin and in mathematical models of aorta mechanics.

Review
Interrupted aortic arch (IAA) is a rare form of critical neonatal heart disease in which there is lack of continuity between the ascending aorta and the descending thoracic aorta. In the absence of prenatal diagnosis, patients with IAA present in shock when the patent ductus arteriosus closes. Diagnosis can generally be made by echocardiography, and initiation of prostaglandin E1 infusion allows for adequate lower body perfusion prior to surgical repair. Full neonatal repair can be achieved with good outcomes in most cases. However, there is often underdevelopment of the left ventricular outflow tract and risk for later surgical re-intervention. Many patients with IAA, particularly those with type B, have DiGeorge syndrome, which has important development implications.

To determine the evolution of the diameter of the thoracic aorta with age in order to detect dilatation more reliably by imaging, we performed a retrospective analysis of the MRI examinations of the normal thoracic aorta of 66 subjects aged 44.1+/-19.1 years (range 19.1-82.4 years) obtained between 1991 and 2000 on a Magnetom SP 42 1T apparatus (Siemens) using T1-weighted spin echo sequences with electrocardiographic synchronization. Sixteen measurements were made in the axial plane, the oblique sagittal plane in the axis of the aortic arch, and the oblique frontal plane perpendicular to the latter at the level of the ascending aorta, the arch and the descending thoracic aorta. We found an increase in the thoracic aorta diameter and a significant relationship between this diameter and the age of our subjects, wherever the measure was performed. However, there was no systematic correlation between aortic diameter and age. The aortic diameter evolved with age and a marked difference seemed to exist in measurements made in groups younger and older than 40 years. This study, conducted on a small population of 66 patients, thus helps to define a normal aortic diameter, thereby making the diagnosis of pathological dilatation of the aorta more reliable.
