Aneurysm III: Interprofessional Care

17
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 I: Introduction

25
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 I: Introduction

22
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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

19
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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

46
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...

Aortic Regurgitation III: Medical Management

33
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...

Summary
This summary is machine-generated.

Retrograde type A aortic dissection (RTAAD) requires tailored treatment. Aggressive surgical repair, excluding the primary entry tear, is recommended to improve outcomes and prevent complications.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Disease

Background:

  • Retrograde type A aortic dissection (RTAAD) presents unique anatomical features distinct from antegrade dissections.
  • Management strategies for RTAAD are not standardized, necessitating further investigation.
  • RTAAD can arise spontaneously or secondary to aortic instrumentation.

Purpose of the Study:

  • To describe the institutional approach to spontaneous RTAAD.
  • To evaluate the outcomes of different treatment modalities for RTAAD.
  • To advocate for an aggressive treatment strategy for RTAAD.

Main Methods:

  • Retrospective analysis of spontaneous RTAAD cases (2018-2022).
  • Review of patient demographics, clinical presentation, and aortic anatomy.
  • Categorization of treatments: emergency surgery (arch/FET replacement), limited proximal repair, conservative management.

Main Results:

  • 15 patients with spontaneous RTAAD were analyzed; mean age 60.1 years, 93% male.
  • Ascending aorta dilation (60%) and distal extension to iliac arteries were common; 27% presented with lower limb malperfusion.
  • Emergency surgery with arch/FET replacement (73%) had a 22% mortality rate, versus 100% for limited proximal repair.

Conclusions:

  • Spontaneous RTAAD often involves the ascending aorta and distal arteries, sparing proximal structures.
  • Aggressive surgical management, including arch/FET replacement, is associated with better survival rates.
  • Excluding the primary entry tear in RTAAD management may prevent immediate and mid-term complications.
