Summary
Acute aortic dissection (TAAD) is often misdiagnosed. This study analyzed 162 patients, finding severe chest pain is the most common symptom, and CT angiography is key for diagnosis.
Area of Science:
- Cardiovascular Medicine
- Radiology
- Surgical Intervention
Background:
- Acute aortic dissection is a life-threatening condition with high rates of misdiagnosis.
- Timely diagnosis and intervention are critical for patient survival.
- Varied clinical presentations contribute to diagnostic challenges.
Purpose of the Study:
- To delineate the presentation patterns, clinical manifestations, and radiological features of Stanford Type A aortic dissection (TAAD).
- To analyze clinical characteristics and radiological findings of TAAD over a 10-year period.
- To compare findings with international aortic dissection registries.
Main Methods:
- Retrospective review of 162 patient records diagnosed with TAAD.
- Analysis of demographic data, comorbidities, clinical symptoms, and radiological findings.
- Comparison of data with International Registry for Aortic Dissection, Japan Registry of Aortic Dissection, and German Registry for Acute Aortic Dissection Type A.
Main Results:
- Severe chest pain was the most common symptom (88.9%).
- Mediastinal widening on chest radiography (88.8%) and dilated ascending aortas on echocardiography (87%) were frequent findings.
- CT angiography was the primary diagnostic tool, revealing dissection flaps in 81.4% of patients.
Conclusions:
- Acute chest pain is the hallmark symptom of TAAD.
- CT angiography is the investigation of choice for diagnosing TAAD.
- TAAD can occur with aortic diameters less than 55 mm, emphasizing the need for clinical suspicion.

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
