In a previous report we stated that two distinct types of aortic dissection exist, namely, the opened-communicated type (O type) which demonstrates communication between the true lumen and the false lumen, and the thrombosed type (T type, also known as aortic dissecting hematoma or as intramural hematoma). The latter, in its acute phase, shows no opacification of the false lumen through medical imagings such as computed tomography (CT) scans or angiography. We analyzed the pathoclinical features of the acute phase. Over a period of 14 years, a study was conducted of 371 patients who were classified as O type and 95 who were classified as T type. The mean age was significantly higher in T-type patients and the sex ratio showed a significantly higher proportion of males. As for atherosclerotic risk factors, such as hypertension and diabetes, hypertension was frequently evident and more frequently seen in T-type patients. The incidence of Marfan's syndrome was 11%, and was not observed in T-type patients. In 18 T-type patients (19%), complications such as cerebral ischemic episodes were observed. However, they were transient and not serious, sometimes indicating only minor surgery.
在之前的一份报告中，我们指出存在两种不同类型的主动脉夹层，即开放连通型（O型），其真腔与假腔之间存在连通，以及血栓形成型（T型，也称为主动脉夹层血肿或壁内血肿）。后者在急性期，通过计算机断层扫描（CT）或血管造影等医学影像检查，假腔无造影剂显影。我们分析了急性期的病理临床特征。在14年的时间里，对371例被归类为O型的患者和95例被归类为T型的患者进行了研究。T型患者的平均年龄显著更高，性别比显示男性比例显著更高。至于动脉粥样硬化危险因素，如高血压和糖尿病，高血压很常见，且在T型患者中更常见。马凡综合征的发病率为11%，在T型患者中未观察到。在18例T型患者（19%）中，观察到了脑缺血发作等并发症。然而，这些并发症是短暂的，并不严重，有时仅表明需要进行小手术。
