Of 48 patients in whom angiography was carried out on the clinical suspicion of spontaneous aortic dissection, the diagnosis could be confirmed in 18 cases only. On the other hand, aortic dissection was discovered incidentally in 14 patients on whom angiography was being carried out for other reasons. The high incidence of incorrect diagnosis is due to the variety of clinical symptoms caused by various types of dissection combined with the non-specific radiological findings on chest radiographs. Unlike plain films, aortography, provided a suitable technique is employed with an understanding of the possible sources of error, gives a high degree of diagnostic certainty with little risk. It is therefore always indicated when the demonstration or exclusion of an aortic dissection is likely to influence treatment.
在因临床怀疑自发性主动脉夹层而进行血管造影的48例患者中，仅18例确诊。另一方面，在因其他原因进行血管造影的14例患者中偶然发现了主动脉夹层。误诊率高是由于各种类型夹层引起的临床症状多样，以及胸部X线片上非特异性的放射学表现。与平片不同，主动脉造影术只要采用合适的技术并了解可能的误差来源，就能在风险很小的情况下提供高度的诊断确定性。因此，当主动脉夹层的显示或排除可能影响治疗时，总是需要进行主动脉造影。
