Summary
Acute aortic dissection can worsen during patient transfer. This case highlights successful treatment of retrograde type A aortic dissection using frozen elephant trunk technology, even without initial symptoms.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Thoracic Surgery
Background:
- Acute aortic dissection poses significant risks during inter-hospital transfer, including aortic rupture or dissection extension.
- Progression from type B to type A aortic dissection can lead to severe complications.
Purpose of the Study:
- To report a case of retrograde type A aortic dissection developing during transfer for type B aortic dissection.
- To demonstrate the efficacy of total arch replacement with a frozen elephant trunk in managing this complication.
Main Methods:
- A 50-year-old male patient with complicated acute type B aortic dissection developed retrograde type A aortic dissection during transfer.
- Open surgical repair with total arch replacement using the frozen elephant trunk technique was performed to address the proximal entry tear.
- Intraoperative direct echography confirmed no intimal tears in the ascending aorta, guiding the surgical approach.
Main Results:
- The patient was successfully treated with total arch replacement using the frozen elephant trunk technique.
- No evident complications were observed post-operatively.
- Satisfactory outcomes were achieved at a 5-year follow-up.
Conclusions:
- Aortic dissection progression can occur asymptomatically during patient transfer, necessitating vigilance.
- Total arch replacement with the frozen elephant trunk is an effective strategy for treating retrograde aortic dissection and resecting intimal tears.

01:26Aneurysm III: Interprofessional Care
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...
01:15Aortic Regurgitation I: Introduction
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...
01:30Aneurysm I: Introduction
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...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
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...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
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...
01:22Aneurysm IV: Nursing Management
Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
