Summary
Open resection (OR) and endovascular aneurysm repair (EVAR) show similar long-term results for abdominal aortic aneurysms (AAA). However, ruptured AAA (RAAA) significantly increases 30-day mortality, and staged procedures require careful patient selection due to higher risks.
Area of Science:
- Vascular Surgery
- Aortic Aneurysm Management
- Surgical Outcomes
Context:
- Abdominal aortic aneurysms (AAA) pose significant health risks.
- Treatment strategies include open resection (OR) and endovascular aneurysm repair (EVAR).
- Patient comorbidities and aneurysm presentation (asymptomatic vs. ruptured) influence outcomes.
Purpose:
- To evaluate the single-center experience in treating patients with AAA.
- Compare the outcomes of OR and EVAR for AAA repair.
- Analyze the impact of comorbidities, ruptured AAA (RAAA), and staged procedures on mortality and survival.
Summary:
- This study analyzed 586 patients undergoing OR or EVAR for AAA between 2000-2009.
- While elective OR and EVAR showed comparable long-term survival, ruptured AAA (RAAA) had a significantly higher 30-day mortality (36.6%).
- One-stage procedures had higher mortality (19.5%) than single procedures (3.6%), and long-term survival was influenced by RAAA, age, complications, and staged procedures.
Impact:
- EVAR and OR demonstrate similar long-term efficacy in AAA treatment.
- Ruptured AAA (RAAA) is associated with substantially increased perioperative mortality.
- Staged procedures necessitate cautious application due to elevated mortality and reduced long-term survival rates.

01:26Aneurysm 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...
01:21Aneurysm 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...
01:22Aneurysm 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...
01:25Aortic 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...
01:30Aneurysm I: Introduction
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...
01:27Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
