BACKGROUND Surgical treatment of non-small cell lung cancer (NSCLC) with aortic invasion is still debated. METHODS Thirteen patients with locally advanced (T4) NSCLC and invasion of the descending aorta underwent pneumonectomy (n=9) or lobectomy (n=4) together with aorta en bloc resection and reconstruction (n=8) or subadventitial dissection (n=5), complete lymph node dissection, and had micr...

Ruptured abdominal aortic aneurysm (RAAA) repair, a combination of hemorrhagic shock and lower-torso ischemia, is associated with a 50-70% mortality. Myocardial dysfunction may contribute to the high rate of mortality after aneurysm repair. We attempted to determine whether RAAA repair results in cardiac dysfunction mediated by tumor necrosis factor-alpha (TNF-alpha). We modeled aortic rupture ...

Objective: The composite mechanical valve conduit has been most commonly used for patients who require combined aortic valve, root, and ascending aorta replacement, but is limited, especially in the elderly, because of the need for long-term anticoagulation. We report the ®rst consecutive series of patients in whom a composite stentless valve with graft extension, which does not require long-te...

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 ...

COMMENT Inadequate organ perfusion is one of the major problems in patients presenting with AADA. Prompt establishment of ante-grade systemic perfusion may prevent further dissection, organ malperfusion and cerebral embolization [2]. Instant antegrade perfusion can be achieved by DTLC of the ascending aorta. Normothermic circulatory arrest of up to 5 min can be tolerated [8], which should enabl...

introduction: our previous studies showed that hydroalcoholic extract of leaf of vitis vinifera relaxes the phenylephrine-induced contraction in rat thoracic aorta. this effect was dependent on endothelial integrity and no-cgmp system. the vasorelaxant effect of extract was much lesser on kcl-induced contraction. we, therefore, postulated that k+ channels are involved. the main aim of the prese...

Introduction: We did this study because there were a few studies about aorto-branch junction. Methods: Four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. Results: Based on the results, there is only one cell type in the tunica intima of endothelium in both art...

Introduction: Patients with primary acute aortic dissection are at higher risk of complications, including increasing aortic aneurysm diameter, aortic rupture, aortic pseudo aneurysm, and recurrent aortic dissection. Case presentation We presented the case of a recurrent pseudo aneurysm and rupture of the aorta in the distal a...

Introduction: Our previous studies showed that hydroalcoholic extract of leaf of Vitis vinifera relaxes the phenylephrine-induced contraction in rat thoracic aorta. This effect was dependent on endothelial integrity and NO-cGMP system. The vasorelaxant effect of extract was much lesser on KCl-induced contraction. We, therefore, postulated that K+ channels are involved. The main aim of the pr...
