چکیده
D a u o s g s a s c p f t h s raumatic aortic injury (TAI) due to blunt trauma remains a highly lethal injury. It is reported to occur in 0.8% of otor vehicle collisions and to account for 16% of the fatalties from motor vehicle accidents.1,2 Mortality at the scene as been reported as 80% in autopsy series.3 Although it ccounts for less than 1% of the trauma admissions to level I rauma centers, TAI represents the second most common ause of death due to blunt trauma after head injury.4 The egion most susceptible to injury is the isthmus, where the elatively mobile thoracic aorta joins the fixed arch and the nsertion of the ligamentum arteriosus.5,6 Aortic ruptures ave been reported to occur at this site in 90 to 95% of cases. he therapeutic approach to these patients is increasingly ontroversial with regard to the timing of surgical or endoascular intervention versus close follow-up for minimal inuries. Recently, endovascular techniques have been used ith success in the treatment of aortic injuries.4,7-16 Emergent urgical exploration has historically been advocated as the ppropriate treatment for patients who present with a trauatic aortic injury.8 Endovascular repair is an especially atractive treatment modality in patients who have severe conomitant injuries, as it is a less invasive technique than onventional surgery.7 Contrast-enhanced computerized tomography (CT), now sing multidetector-row technology, has replaced traditional ngiography as the screening diagnostic tool for TAI.7 This eview delineates the current imaging evaluation of TAI, with ocus on multidetector-row CT and with discussion of the ey imaging findings that allow its diagnosis.

Detection of endograft fractures with multidetector row computed tomography.
Delayed endograft metallic strut failures detected in vivo with multidetector row computed tomography (MDCT) are reported in two patients who underwent endovascular abdominal aortic aneurysm repair with AneuRx and Talent endografts. In both instances, nitinol fractures were associated with proximal migration and type I endoleak. In both cases, the metallic strut fractures were detected with tra...

Pseudoaneurysm in the left ventricular outflow tract after prosthetic aortic valve implantation: evaluation upon multidetector-row computed tomography.
The high accuracy of multidetector-row computed tomography (MDCT) in evaluating prosthetic valve disorders has been confirmed. This, we believe, is the 1st report of the use of MDCT to detect and evaluate left ventricular outflow tract (LVOT) pseudoaneurysms in patients who have undergone aortic valve replacement with prosthetic valves. We used MDCT to scan 21 such patients, 3 of whom had a sma...
متن کاملDiagnosis of an ilio-iliac arteriovenous fistula by multidetector row computed tomography and surgical repair.
An 82-year-old man presented with typical signs and symptoms of an arteriovenous fistula (AVF) associated with an aortoiliac aneurysm, such as a pulsatile abdominal mass, continuous bruit, thrill, and high output heart failure. Multidetector row computed tomography (MDCT) confirmed the presence of an AVF between the right common iliac artery aneurysm and vein. We subjected the patient to surgic...
متن کاملAortic valve replacement after esophagectomy with substernal gastric tube reconstruction.
A 67-year-old woman with a history of esophagectomy with substernal gastric tube (GT) reconstruction and left lower lobectomy required aortic valve replacement (AVR) for aortic valve regurgitation and stenosis. Through a median sternotomy (MS) with cardiopulmonary bypass (CPB), we performed AVR without injury to the GT. Careful peeling of the GT and detailed information of the operative field b...
