We report an extremely rare case of Synchronous primary intrapulmonary and mediastinal thymoma in a Chinese patient. We describe the histological and radiological findings, which support the possibility of multicentric thymoma. Resection of the mass in the left anterior superior mediastinum and upper lobectomy of right lung were performed, with lymph Nodes clearance, superior vena cava, left an...

An 81-year old woman with high fever and a history of hospital admission because of pyelonephritis 3 months previously was transferred to our hospital. Contrast-enhanced computed tomography revealed a mycotic pseudoaneurysm in the ascending aorta and a massive pericardial effusion. We resected the ascending aorta and the proximal part of the brachiocephalic artery and performed in situ revascul...

Percutaneous implantable device extraction has increased in recent years and is associated with small but significant risk. Arteriovenous fistula formation is an uncommon complication of this procedure. We report two cases where lead extraction was complicated by an arteriovenous fistula between the left internal mammary artery and the left brachiocephalic vein. In both cases, the patients were...

A 73-year old woman with factor V Leiden deficiency and a history of deep venous thrombosis ceased taking oral warfarin. She sustained a massive cerebral infarct following extensive paradoxical embolism involving the brachiocephalic artery and the aorta (Fig. 1A and B). Transoesophageal echo findings (Fig. 2A and B) can be viewed in Supplementary Videos 1 and 2. Supplementary material (Videos 1...

Matrix metalloproteinases (MMPs) are a family of approximately 30 structurally related Zn endopeptidases that each degrades several extracellular matrix (ECM) proteins as well as nonmatrix substrates.1 Although membrane-type MMPs are integral membrane proteins, most MMPs are secreted or confined to the pericellular environment by binding to surface receptors. Their activity is tightly controlle...

OBJECTIVE We sought to determine the patency of normal arterial branches from the covered segments of an artery after stenting. BACKGROUND Most intracranial aneurysms occur at arterial branching points (bifurcations, side-branches, or perforators). The post-stenting patency of normal arterial branches from the covered segments of the artery is important. We have previously developed a hybrid ...

Three patients with Takayasu's disease are described. In 2 cases aortography demonstrated an occlusion of the great vessels at the origin of the arch of the aorta. In 1 patient there was concomitant aneurysmal dilatation of the brachiocephalic trunk. Common and internal carotid artery stenosis occurred in 1 patient and was associated with hemiplegia and blindness. All 3 patients had constitutio...

Percutaneous transluminal angioplasty was used to treat atherosclerotic lesions in 22 brachiocephalic arteries in 20 patients during a 2 1/2 year period. Seven subclavian, 13 vertebral, one external carotid, and one common carotid arteries were involved. Nineteen arteries were successfully dilated, but dilatation of two vertebral arteries and attempted recanalization of one subclavian artery fa...
