Abstract
- Aortic dissection (AD) is a serious, life-threatening disease. It is currently crucial for AD patients to be transferred to a specialised hospital in a safe and timely manner. For this reason, the search for clinical and imaging changes related to transportation risk is becoming increasingly important. The transportation risks of AD patients were assessed by studying the correlation between computed tomography angiography (CTA) parameters and shock index. Thirty-six cases of AD confirmed with 64-slice volumetric CT (VCT) (18 cases of Stanford type A and 18 cases of type B) were divided into a high-risk group (14 cases, six Stanford type A and eight type B) and a low-risk group (22 cases, 12 Stanford type A and 10 type B) according to the modified Early Warning Score. The shock index (ratio of heart rate to systolic blood pressure) and measured CTA parameters were compared between the high-risk group and the low-risk group, and the correlation between the measured CTA parameters and shock index was analysed. The shock index and ratio of false/true lumen were compared between Stanford type A and type B, and no statistically significant differences were found. The shock index and ratio of false/true lumen were compared between the high-risk group and low-risk group, revealing a statistically significant difference (p
