traumatic false aneurysm of the thoracic aorta is not uncommon. but accordingly this case is unusual in its ten year delay between injury and presentation and treatment. a victim of the iran-iraq war is presented with a false aneurysm of the thoracic aorta ten years after a bullet injury to the chest and thoracic spine. penetrating chest wounds, mechanisms of injury and diagnosis are also discu...

THORACIC PARASPINAL LINE IN HYPERTENSION AND MITRAL VALWLAR DISEASE. S.K. Gupta and V. Mohan. Institute of Medical Sciences, Banaras Hindu university, Varanasi, India. Thoracic paraspinal line produced by the posteromedial border of the left lung casts a linear shadow running along the left side of thoracic spine from the level of D4 to Dll or D12 vertebra medial to the shadow of descending tho...

aortic dissection begins with the formation of a tear in the aortic intima, and it directly exposes an underlying diseased medial layer to the driving force of the intraluminal blood. this blood penetrates the diseased medial layer and cleaves the media longitudinally, thereby dissecting the aortic wall. herein, we report the case of a 38-year-old woman, who presented with chest pain and dyspne...

Blunt aortic injury is the most lethal injury of the thorax, of which aortic transection is the second leading cause of death. Pseudoaneurysm formation is seen in patients who survive the injury and arrive to the emergency department with small or partial-thickness tears of the aorta. In general, the proximal descending aorta is most commonly afflicted due to the relatively mobile aortic arch m...

Thoracic endovascular aortic repair (TEVAR) is used to treat retrograde type A acute aortic dissection (RTAAD). In case 1, a 52-year-old man, who was conservatively managed, reported worsening back pain. Emergency TEVAR was performed 7 days after onset. After deploying two GORE Conformable TAG (CTAG) in the descending aorta, his symptoms disappeared. In case 2, a 52-year-old man with progressiv...

We report the case of a 78-year-old man with an extended thoracic aortic aneurysm in whom replacement of the ascending aorta, aortic arch, and descending aorta were performed by single-stage repair. Single-stage repair surgical approach in this case was selected rather than two-stage repair because of the risk of rupture of the aneurysm in the period before the second surgery and the patient's ...

Abstract Aim A thoracic aortic aneurysm (TAA) is a pathological dilatation of the aorta. There significant morbidity associated with dilated aorta including mortality. Open surgery mainstay management for proximal lesions, offering definitive treatment. We aim to evaluate outcomes patients operated on TAA and consider high risk associations Method Data was retrospectively collected from 234 tha...

PURPOSE To assess 3-dimensional (3D) pulsatile displacement forces (DF) acting on thoracic endografts using 3D computational techniques. METHODS A novel computational method to quantitate the pulsatile 3D flow and pressure fields and aortic wall dynamics in patient-specific anatomical models based on cardiac-gated computed tomography (CT) scans was used to construct simulations of the proxima...

A three-dimensional and pulsatile blood flow in a human aortic arch and its three major branches has been studied numerically for a peak Reynolds number of 2500 and a frequency (or Womersley) parameter of 10. The simulation geometry was derived from the three-dimensional reconstruction of a series of two-dimensional slices obtained in vivo using CAT scan imaging on a human aorta. The numerical ...

We present the case of a male patient aged 74 years, who came to our hospital’s emergency room due to presenting intense central chest pain while exercising, which then descended caudally. He was a former smoker who had quit 5 years earlier, and had no other cardiovascular risk factors. As pulmonary thromboembolism was initially suspected, we performed a thoracic computerised tomography (CT) an...
