Abstract 19166: Transportation Time Does Not Affect Mortality in Patients With Type A Aortic Dissection in a Hospital Without Cardiothoracic Surgery
Introduction: Acute aortic dissection (AD) is a rare case, but if it occurs rapid diagnosis and treatment are needed. It is currently crucial for AD patients to be transferred to a specialized hospital in a safe and timely manner. However, transportation time does not fully access to affect mortality in these patients.
Methods: We evaluated fifty-one subjects who were suspected aortic dissection between 2010 and 2014 in a hospital without cardiothoracic surgery. Thirty cases of AD confirmed with 64-slice computed tomography (20 cases of Stanford type A and 10 cases of type B) were divided into a high-risk group (eight cases, 8 Stanford type A and zero type B) and a low-risk group (22 cases, 12 Stanford type A and 10 type B) according to the hypotension (systolic blood pressure<90 mmHg). The transportation time and mortality were compared between the high-risk group and the low-risk group, and the correlation between the measured transportation time and mortality was analyzed.
Results: The transportation time and mortality were compared between Stanford type A and type B, and statistically significant differences were found. The transportation time and mortality were compared between the high-risk group and low-risk group, revealing a statistically significant difference (p < 0.05). Moreover, a significant correlation was not found between the transportation time and mortality (r = 0.287; p = 0.367). CONCLUSIONS: The hypotensive patients are the greater transportation risk for AD patients with type A dissection. Transportation time does not affect mortality in patients with low-risk type A aortic dissection.
