An active, 74-year-old man with coarctation of the aorta is described. This case is rarely found in patients over the age of 70, and the patient had been in good health. 相似文献

Four members in three generations of a family were affected by a coarctation of the aorta (CoA) which was mild or severe, either isolated or in association with other cardiac defects. This family suggests that a rare form of CoA could be the result of an autosomal dominant mutation with incomplete penetrance and variable expressivity rather than polygenic inheritance. 相似文献

The time course of the vascular permeability disorder following upon acute hypoxia and the fate of plasma substances entering the vessel wall in consequence of increased permeability were studied on the rat abdominal aorta rendered hypoxic for one hour by double ligature and recirculated for periods ranging from one hour to 30 days. The distribution and quantity of mural plasma inhibition were determined histochemically by means of a colloidal iron tracer and Prussian blue reaction and by photometric analysis, respectively. Plasma imbibition reached its maximum after recirculation for 24 to 48 hours and fell to an almost normal level after 10 days. Administration of the colloidal iron tracer on the second day of recirculation, when the permeability disorder was at its peak, showed plasma imbibition in every layer of the vessel wall. At seven days it was restricted to the outer third of the media and the adventitia. The endothelium is acting as the main barrier to mural plasma imbibition and in the case of a permeability disorder only the elastic lamellae constitute a temporary mechanical obstacle to the ingression of plasma. 相似文献
