Aneurysm II: Clinical Manifestations and Diagnostic Studies

589
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...

Aneurysm III: Interprofessional Care

478
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...

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

1.2K
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...

Aneurysm I: Introduction

650
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...

Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

598
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

Total aortic arch replacement has significant risks, but this study shows low in-hospital mortality and stable long-term survival for patients, particularly those avoiding dialysis post-surgery.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • Total aortic arch replacement is a complex procedure with substantial risks of mortality and morbidity.
  • Postoperative complications can significantly impact the quality of life for survivors.

Purpose of the Study:

  • To evaluate the short-term and long-term outcomes of total aortic arch replacement.
  • To identify risk factors associated with in-hospital death and major postoperative morbidity.
  • To assess long-term survival and mortality risks in hospital survivors.

Main Methods:

  • Retrospective analysis of 146 patients undergoing total aortic arch replacement between September 2003 and September 2011.
  • Multivariate analyses were used to identify independent risk factors for mortality and morbidity.
  • Long-term survival and standardized mortality ratios were calculated and compared to the general population.

Main Results:

  • In-hospital mortality was 4.8%, with major postoperative morbidity in 19.9% of patients.
  • Independent risk factors for hospital death included left thoracotomy, elevated creatinine, and intraoperative blood loss.
  • Risk factors for major morbidity included ruptured aorta and prior myocardial infarction. Five-year survival was 76.7%. Renal failure requiring hemodialysis significantly increased long-term mortality risk.

Conclusions:

  • The studied approach for total aortic arch replacement demonstrates favorable in-hospital outcomes.
  • Long-term survival is generally stable for hospital survivors.
  • Avoiding postoperative dialysis is crucial for improved long-term prognosis.
