Insights

Managing ruptured abdominal aortic aneurysm (rAAA) during the COVID-19 pandemic is feasible. A perioperative workflow and infection control strategy ensured effective treatment outcomes for rAAA patients.

Area of Science:

  • Vascular Surgery
  • Infectious Disease Epidemiology
  • Public Health

Background:

  • The COVID-19 pandemic presents challenges for managing vascular emergencies like ruptured abdominal aortic aneurysms (rAAA).
  • Ensuring uncompromised treatment for rAAA during a global health crisis is crucial.
  • This study evaluates rAAA treatment outcomes and infection prevention strategies during the pandemic.

Purpose of the Study:

  • To assess the effectiveness of a perioperative workflow for rAAA management during the COVID-19 pandemic.
  • To evaluate infection prevention measures for healthcare providers and patients undergoing rAAA surgery.
  • To compare treatment outcomes of rAAA before and during the COVID-19 pandemic.

Main Methods:

  • A retrospective analysis of rAAA cases treated in 11 vascular centers from January to March 2020.
  • Comparison of data with the same period in 2018 and 2019.
  • Implementation of a perioperative workflow including expedited coronavirus testing and cross-infection prevention strategies.

Main Results:

  • Patient numbers for rAAA increased from 2018 to 2020, with a higher proportion treated locally.
  • Endovascular aneurysm repair (EVAR) was the primary strategy in 2020 (85.7%), similar to previous years.
  • Surgical outcomes were not inferior to pre-pandemic levels, with reduced ICU stay and significantly lower in-hospital mortality (14.3% in 2020 vs. 37.5% in 2018).

Conclusions:

  • The implemented perioperative workflow and infection prevention strategies were effective for managing rAAA during the COVID-19 pandemic.
  • Emergent surgical outcomes for rAAA were optimized.
  • The approach ensured the safety of healthcare providers and patients.

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 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...

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 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...

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...
