Summary
Open conversions (OCs) after endovascular aneurysm repair (EVAR) often lead to poor outcomes. However, elective OCs for type II endoleaks with endograft preservation show promising results with no mortality.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Aneurysm Repair
Background:
- Secondary interventions after endovascular aneurysm repair (EVAR) are a clinical concern.
- While most are minimally invasive, open conversions (OCs) are sometimes necessary and associated with worse outcomes.
Purpose of the Study:
- To review the experience with open conversions (OCs) after endovascular aneurysm repair (EVAR).
- To characterize the indications, procedures, and outcomes of OCs.
Main Methods:
- Retrospective review of patients undergoing OC after EVAR for aneurysm-related indications between 2001 and 2010.
- Analysis of clinical outcomes, including morbidity and mortality.
Main Results:
- 44 patients underwent OC, with indications including aneurysm expansion (64%), rupture (27%), and infection (9%).
- Overall morbidity was 55% and mortality was 18%.
- Elective OCs for type II endoleaks with endograft preservation and selective ligation of culprit vessels resulted in no deaths.
Conclusions:
- Open conversions after EVAR are generally associated with significant morbidity and mortality.
- Elective OC for isolated type II endoleak with endograft preservation is a safe and effective strategy, avoiding explantation and subsequent procedures.

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...
01:22Aneurysm 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...

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...
01:30Aneurysm 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...
