“…This shows that this model is a good diagnostic model of AD. Clinically, the misdiagnosis rate of AD is close to 40% [3][4] [5]. The model performance data show that this algorithm can not only reduce the workload of doctors, but also reduce the misdiagnosis rate of AD to save patients' lives effectively.…”

Background: Aortic dissection (AD) is a rare and high-risk cardiovascular disease with dangerous morbidity and high mortality, so it needs rapid diagnosis and timely treatment. However, due to its complex and changeable clinical manifestations and the lack of special symptoms and signs, it is easy to cause missed diagnosis and misdiagnosis.Methods: The data set used in this paper comes from 53213 patients, which collected from XiangYa Hospital in Hunan Province from 2008 to 2016. The data includes 802 patients with aortic dissection and 52411 patients with non-aortic dissection. In order to help clinicians predict AD, we designed an ensemble learning model based on clustering: Cluster Random Under-sampling Smote-Tomek-link Bagging (CRST-Bagging). This model combines the advantages of clustering-based compound resampling (CRST) method and Bagging ensemble classifier. It achieves good results on aortic dissection data sets.Results: The model validates the effectiveness of the CRST sampling method on the AD data set. We compared the CRST-Bagging model with the classical ensemble models RUSBoost and SMOTE-Bagging on the AD data set. The experimental results show that the CRST-Bagging model has the best performance in the detection of AD. Model’s accuracy and recall rate are 83.6% and 80.7% respectively. And the F1 value is 82.1%, which is 4.8% and 1.6% higher than that of RUSBoost and SMOTE-Bagging model.Conclusions: The model proposed in this paper can be used as an auxiliary diagnostic model of AD to provide reference for clinical medicine. The model can also help doctors to judge whether patients need further imaging examination. Thus help to reduce the rate of clinical misdiagnosis and missed diagnosis of AD.

“…It is easy to cause missed diagnosis and misdiagnosis [2]. According to the clinical statistics, the misdiagnosis rate of AD is more than 1/3 in the actual cases of AD [3][4] [5]. Mortality can reach as high as 50% within a week of onset and between 60 and 70% within a month.…”

“…When assessing a patient with suspected aortic dissection, the quality, radiation and intensity of pain should be considered. The most common presenting complaint is sudden-onset tearing chest pain radiating to the back, associated with a drop in blood pressure or pulse deficit in the upper limbs [1] . These symptoms are present in fewer than 50% of confirmed cases of acute aortic dissection (AAD) [2] .…”

“…Stanford type A involves the ascending aorta and accounts for 60% of aortic dissections, while type B occurs distal to the left subclavian artery. Type A aortic dissection is misdiagnosed in 40% of cases due to overlap with acute coronary symptoms [1] . Type A presents with a higher mortality rate and therefore requires prompt surgical treatment and management [1] .…”

Aortic dissection is a relatively uncommon, although catastrophic, disease which requires early and accurate diagnosis and treatment for patient survival. Aortic dissection can be difficult to diagnose due to the diverse symptom presentation, which can lead to later diagnosis, resulting in a higher mortality rate. Here we present a case of type A aortic dissection with a varied symptom presentation, highlighting the importance of early detection and the Bentall procedure for management of such cases. A 50-year-old man with no known medical history presented with bilateral lower extremity swelling and fatigue for 2 weeks. The patient denied any chest pain or dyspnoea. Vital signs showed blood pressure of 160/76 mmHg, pulse of 103 bpm, respiratory rate of 18, and temperature of 36.7°C. Laboratory findings indicated a BNP of 1901 pg/ml and troponin of 0.5 ng/ml. An initial diagnosis of decompensated heart failure was made, and IV Lasix was started. Subsequently, an echocardiogram indicated an EF of 50–55% and ascending dissection of the aorta. A CT angiogram of the chest and abdomen confirmed this diagnosis. This patient presented with unusual symptoms of aortic dissection without the typical presentation of chest pain. It is important to consider aortic dissection in a cardiac-related case as prompt imaging can help confirm the diagnosis. We explore the risks and benefits of the Bentall procedure for the management and early detection of aortic dissection.

Aortic dissection type A is a life-threatening condition that frequently necessitates surgical intervention. This review focuses on central aortic cannulation, arch branch vessel (ABV) cannulation, and proximal arch cannulation as key techniques during aortic surgery. It discusses innovative solutions for addressing these challenges. The review synthesizes findings from recent studies and emphasizes the significance of meticulous planning and execution of cannulation in aortic dissection repair. This review aims to contribute to the advancement of surgical practices and the enhancement of patient outcomes in the management of type A aortic dissection (AAD) by addressing these frequently overlooked details.
