Aortic infarction was observed in 21 of 34 cases of dissecting aortic aneurysm. This lesion occurred as a central zone of necrosis with preserved elastic laminae, sparing media adjacent to the true and false lumens. In cases where the false lumen was occluded, the central infarction extended to this lumen. The infarction followed rather than preceded dissection, took approximately 48 hours to develop, and did not organize with time. The lesion occurred exclusively in the thoracic aorta, and bore no relationship to medial cystic necrosis. Present surgical therapy does not extirpate these areas, and the implication of these lesions in terms of management remains to be determined.
在34例主动脉夹层动脉瘤中，观察到21例存在主动脉梗死。该病变表现为中央坏死区，弹性膜保留，真假腔相邻的中膜未受累。在假腔闭塞的病例中，中央梗死扩展至该腔。梗死发生在夹层之后而非之前，大约需要48小时发展形成，且不会随时间机化。该病变仅发生于胸主动脉，与中膜囊性坏死无关。目前的外科治疗无法切除这些区域，这些病变在治疗方面的意义仍有待确定。
