Summary
A patient developed infected aortic pseudoaneurysms after surgery. Surgical repair and antifungal treatment successfully eradicated the Aspergillus fumigatus infection, with no recurrence after one year.
Area of Science:
- Cardiology
- Infectious Diseases
- Cardiovascular Surgery
Background:
- Aortic pseudoaneurysms can arise after cardiac procedures.
- Invasive fungal infections pose a significant risk in cardiovascular surgery patients.
Purpose of the Study:
- To report a case of invasive Aspergillus fumigatus infection presenting as infected pseudoaneurysms of the ascending aorta and aortic root.
- To describe the successful management of this rare complication.
Main Methods:
- Surgical aortic root replacement using a homograft.
- Postoperative treatment with voriconazole.
- Clinical and imaging follow-up for one year.
Main Results:
- Invasive Aspergillus fumigatus was identified in operative specimens.
- The patient recovered well after surgery and antifungal therapy.
- No recurrence of pseudoaneurysm or fungal infection was observed at one-year follow-up.
Conclusions:
- Invasive fungal infections can complicate aortic surgery.
- A homograft combined with appropriate antifungal therapy can be effective in managing infected aortic pseudoaneurysms.
- Long-term surveillance is crucial for patients with fungal aortic infections.

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...

449
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...

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...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

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...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
604
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...
