Summary
A thoracic aortic aneurysm presented unusually as a persistent dry cough. Surgical repair with a frozen elephant trunk technique successfully resolved symptoms and reduced aneurysm size.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Medicine
Background:
- Thoracic aortic aneurysms (TAAs) are serious conditions often asymptomatic until rupture.
- Atypical presentations of TAAs, such as respiratory symptoms due to compression, are less common.
- This case highlights an unusual cause of subacute cough.
Observation:
- A 74-year-old female with hypertension and dyslipidemia presented with a one-month history of dry cough.
- Imaging revealed a large saccular aortic arch aneurysm compressing the left lung.
- The aneurysm protruded anteriorly, suggesting significant mass effect.
Findings:
- Open surgical repair using the frozen elephant trunk technique was successfully performed.
- Postoperative follow-up at six months showed complete resolution of the cough.
- Aneurysm sac shrinkage was confirmed six months after the intervention.
Implications:
- This case underscores the importance of considering thoracic aortic aneurysms in patients with unexplained respiratory symptoms.
- Surgical intervention, including the frozen elephant trunk technique, can be effective for large, symptomatic aortic arch aneurysms.
- Early diagnosis and treatment are crucial for favorable outcomes in TAA management.

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...

59
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...

01:15Aortic Regurgitation I: Introduction
38
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...

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...

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
