The pathology of atherosclerosissed focal plaque within the intima, having a core of lipid (mainly cholesterol, usually complexed to proteins and cholesterol esters) and a covering fibrous cap. These atheromata are sparsely distributed at first but as the disease advances they become more numerous and sometimes cover the entire intimai surface of the severely affected arteries.作者: Buttress 時間: 2025-3-22 01:00
Risk factors and epidemiology in the pathogenesis and clinical progress of occult coronary artery diarteries, and it has been postulated that some of these patients may have atherosclerosis in the intra-mural coronary branches. In this chapter we will review some of the information on these subgroups of patients, particularly relating to risk factors and epidemiology, and present data from our own research in this area.作者: 上坡 時間: 2025-3-22 06:21

When an aneurysm ruptures anteriorly through the posterior peritoneum there can be no tamponade of the haemorrhage and exsanguination into the peritoneal cavity is immediate. Such patients seldom reach hospital alive and have no chance of surgical rescue. In some 40作者: choroid 時間: 2025-3-25 09:49 作者: 轎車 時間: 2025-3-25 12:08
