We describe the case of a 68-year-old man seen in the emergency room for sudden piercing chest pain radiating toward the back. The electrocardiogram and analytical parameters were normal; however, the chest x-ray showed mediastinal widening. The chest and abdominal computed tomography (CT) revealed DeBakey type 1 aortic dissection and TTE showed severe aortic regurgitation. The patient underwen...

Acute disruption of the thoracic aorta due to blunt chest trauma is a life-threatening injury. The majority of patients with an aortic tear die at the scene while approximately 15-20% of the victims reach the hospital alive. A 25 years old man was admitted to emergency service because of traffic accident. On the chest X ray; left pleural effusion, left apical pleural cap, the evanescence of aor...

This paper deals with aneurysmal disease, primarily when localized in the abdominal aorta. It is based on the Olof Rudbeck lecture 2009. Aneurysm is a localized widening of an artery, and its definition has become an important issue today when the disease is in focus for screening programmes. Aetiology and pathogenesis are still poorly understood, but a genetic component determining the strengt...

This article is concerned with the analysis of blood flow through arterial catheterization (widening of arteries by a balloon in the presence of mild stenosis), when blood is represented by MHD Newtonian fluid. The mild stenosis approximation is used to solve the problem. A uniform magnetic field is applied perpendicular to the porous artery. A mathematical model is developed and analyzed by us...

BACKGROUND Dolichoectasia of intracranial arteries is a rare arteriopathy characterized by elongation and widening of the arteries and disturbance of the laminar blood flow. It involves mostly vertebral and basilar arteries. In advanced cases, formation of a fusiform aneurysm is possible. CASE REPORT A sixty-four-year-old female with hypertension was admitted to the hospital with severe non-s...

Mok Ka Leung, FHKCEM Kan Pui Gay, FHKCEM Wong Yau Tak, FHKCEM We describe the ultrasound evaluation technique and sonographic findings of a case of anterior shoulder dislocation. The sonographic features of anterior shoulder dislocation include: "sign of widening of subacromial space", "sign of disappearance of humeral head", "artery/vessel sign", "humeral head below coracoid process sign" and ...

The umbilical artery was chosen as a possible model for evaluating the vascular injury provoked by tobacco smoking in humans. Cords from newborn children delivered by 15 nonsmoking and 13 smoking mothers were studied in the transmission and the scanning electron microscope. Pronounced intimal changes were seen in the arteries from smoking mothers; the most important findings were degenerative c...
