Insights

Long-term survival after open thoracic aortic surgery is excellent, with 77.7% survival at 5 years. Improved outcomes are seen in the modern era, aiding risk stratification for patient selection.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Aortic Surgery
  • Surgical Outcomes

Background:

  • Long-term survival after open thoracic aortic surgery is not well-documented.
  • Open aortic surgery may offer superior durability compared to endovascular techniques.

Purpose of the Study:

  • To determine long-term survival rates after open thoracic aortic surgery.
  • To identify predictors of mortality in patients undergoing this procedure.

Main Methods:

  • Analysis of a provincial database of adult patients undergoing primary open thoracic aortic surgery (1993-2010).
  • Kaplan-Meier survival analyses and multivariate analyses to identify mortality predictors.

Main Results:

  • Overall 30-day mortality was 9.1%; 5-year survival was 77.7%.
  • Improved long-term survival observed in the modern era, for elective surgeries, and ascending aorta/root procedures.
  • Preoperative factors like age >65, renal failure, COPD, and cerebrovascular accident were associated with decreased survival.

Conclusions:

  • Elective thoracic aortic surgery demonstrates excellent long-term survival, with outcomes improving over time.
  • Identified preoperative risk factors can aid in risk stratification and patient selection.
  • Established survival rates serve as a benchmark for new aortic interventions.

Aneurysm 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...

Aneurysm 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...

Aneurysm 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...
Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

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...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Aortic Regurgitation I: Introduction01:15

Aortic 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...
