Thoracic endovascular aortic repair (TEVAR) has become increasingly popular for the treatment of descending thoracic aortic aneurysms. Despite their proven efficacy and safety, several complications can occur with TEVAR. We report a case of a 76-year-old woman with a late-term complication after TEVAR related to recurrent thyroid cancer and carotid-subclavian ...

BACKGROUND: The presentation of a ruptured fusiform abdominal aortic aneurysm (AAA) co-occurring with bilateral iliac dissections is extremely rare. Endovascular repair of ruptured AAA is an accepted treatment modality for suitable patients; however, this approach may be complicated by the presence of iliac arterial pathology. METHODS AND RESULTS: We report ...

Peripheral embolization is a known complication of peripheral artery interventions. It can lead to occlusion of distal vessels leading to significant lower extremity ischemia and complications. Peripheral artery interventions involving chronic total occlusions have been shown to have higher rates of complications including distal embolization. Although distal embolic protection strategies ...

Fusiform basilar aneurysm is a rare condition with elevated mortality within a few days if untreated. On the basis of clinical course, the fusiform aneurysm can be distinguished in an acute type, such as dissecting aneurysm, which usually causes subarachnoid hemorrhage or cerebral ischemia and in a chronic type with ...

Emissary veins are valveless veins which pass through the cranial apertures and connect the dural venous sinuses and the extracranial veins. The clinical importance of emissary veins is increasingly being appreciated. Some emissary veins like the petrosquamosal sinus and mastoid emissary vein may cause significant bleeding during middle ear and ...

Aortic aneurysm is common, accounting for 1-2% of all deaths in industrialized countries. Early theories of the causes of human aneurysm mostly focused on inherited or acquired defects in components of the extracellular matrix in the aorta. Although several mutations in the genes encoding extracellular matrix proteins have been recognized, ...

Internal carotid artery (ICA) is predominant localization of giant intracranial aneurysms (GIAs). The rupture of GIA is supposed to be related to higher risk of poor clinical outcome. Although endovascular techniques are still being developed, they seem to be unsatisfactory in the mean of GIAs. Included in the retrospective analysis ...

Tissue-type plasminogen activator (tPA) is a potent fibrinolytic enzyme used to treat acute coronary artery obstruction. However, tPA has shown limited utility in other disorders caused by thrombotic vascular occlusion, such as pulmonary embolism. We found that tPA caused dose-dependent effects on the contractility of pulmonary arterial rings that may ...

Thrombosis is a well known complication of subclavian vein catheterization. As collateral circulation develops, consequences are usually limited to the fact that this vein is no longer usable as an access route. However, one of the possible complications of a superior vena cava thrombosis is the development of a chylothorax. ...
