Summary
Brucellosis can cause rare aortic aneurysms. Management varies, with one patient treated surgically and another conservatively with antibiotics, highlighting the need for awareness in endemic regions.
Area of Science:
- Infectious Diseases
- Vascular Surgery
- Cardiology
Background:
- Brucellosis is a zoonotic disease with systemic effects.
- Mycotic aneurysms, particularly those caused by Brucella, are infrequent and lack standardized treatment protocols.
Observation:
- Two cases of mycotic aortic aneurysm caused by Brucella are presented.
- The first case involved surgical resection of an infrarenal abdominal aortic aneurysm with long-term antibiotic therapy (doxycycline and rifampicin).
- The second case showed improvement with conservative management, including a six-month antibiotic course and ongoing monitoring.
Findings:
- Successful management of Brucella-related mycotic aortic aneurysms can be achieved through both surgical intervention and conservative antibiotic therapy.
- Individualized treatment approaches are crucial given the rarity and varied presentations of these aneurysms.
Implications:
- This study emphasizes the importance of recognizing Brucella as a potential cause of mycotic aneurysms.
- It highlights the need for tailored management strategies for arterial complications of brucellosis, especially in areas where the disease is endemic.
- Increased clinical suspicion and appropriate diagnostic workup are essential for timely intervention.

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...

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 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...

01:15Aortic Regurgitation I: Introduction
536
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...

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...

416
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...
