Despite much advancement in preoperative evaluation and perioperative care of patients with thoracoabdominal aortic aneurysms (TAAA), open surgical repair of TAAAs remains a formidable challenge for the vascular surgeon. It requires extensive dissection and mobilization of the aorta and its branches, as well as cross-clamping of the aorta above intercostal and visceral arteries. Over the past d...

Compared with the pursed-lip breathing technique, acute application of portable noninvasive ventilation during recovery from intermittent exercise improved end-expiratory thoracoabdominal dynamic hyperinflation (DH) in 50% patients COPD (DH responders). DH responders, compared nonresponders, exhibited a reduction predominantly driven by abdominal compartment that effectively offset rib cage DH....

Situs ambiguous is the placement of vessels and organs in thoracoabdominal space that are anatomically located outside its normal position a certain order. This condition broad definition includes many variations. In this case report, we reported patient with ambiguus an abnormal hepatic vein who was diagnosed incidentally during medical imaging (computed tomography, sonography MRI study).

A 27-year-old male suffered an accidental fall onto the branch of a tree, resulting in thoracoabdominal impalement with entry site below the left clavicle. A chest-abdominal computed tomography (Fig. 1A and B) revealed subcutaneous emphysema in the chest wall, large left pneumothorax with collapsed lung, parenchymal lesions in both lung lobes and the presence of a foreign body with air density,...

T he classic anatomic definition of a Crawford type IV thoracoabdominal aortic aneurysm (TAAA) is that of aneurysms extending from the 12th intercostal space to the iliac bifurcation involving the visceral aortic segment and the origins of the renal, superior mesenteric, and celiac arteries.1 In the endovascular era, however, some investigators have moved away from this strict anatomic criteria...

Movements of the thorax and abdomen during respiration are of interest from two points of view. First, such movements can be measured and provide a quantitative assessment of pulmonary ventilation. Secondly, thoracic and abdominal motions offer insight into the actions of the respiratory muscles. Mead and co-workers 11-31 demonstrated a practical means of recording and calibrating thoracic and ...

Although open surgical repair of thoracoabdominal aortic aneurysm (TAAA) has evolved significantly over the last few decades, technical challenges and current morbidity and mortality of the inclusion technique are still significant, particularly in patients with extensive aneurysms or prior aortic surgery and in poor surgical candidates. Hybrid TAAA repair is an appealing technique and may repr...

A strategy employing moderate hypothermia for the replacement of the aortic arch is proposed to avoid the complications of profound hypothermic circulatory arrest. Two patients underwent the complete replacement of the aortic arch using three pumps - for the brain, thoracoabdominal aorta, and heart, respectively. There were no complications and the patients were extubated uneventfully. The meth...

Medical investigation included angiotomography (May 23, 2005) which revealed enlargement of the mediastinum due to a bulky aneurysm in the thoracic aorta in its arch and descending portion, measuring 9 cm in transversal diameter and 7 cm in length, as well as mural thrombosis and an aneurysm at the thoracoabdominal junction with dimensions of 5 cm by 4 cm. Bilateral pleural effusions were detec...
