Summary
Endovascular aneurysm repair (EVAR) is effective but can cause complications like endograft collapse. This case highlights a rare instance of proximal endograft collapse alongside acute aortic dissection in a previously treated patient.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Diseases
Background:
- Endovascular aneurysm repair (EVAR) is a standard treatment for abdominal aortic and iliac aneurysms.
- EVAR is associated with potential complications necessitating reintervention.
- Proximal endograft collapse is an infrequent but serious complication of EVAR.
Purpose of the Study:
- To report a rare case of abdominal endograft proximal collapse.
- To describe the simultaneous occurrence of acute type A aortic dissection in a patient with prior EVAR.
- To discuss the management challenges of combined EVAR complications and aortic dissection.
Main Methods:
- Case report presentation.
- Review of patient's medical history and imaging.
- Discussion of endovascular repair (EVAR) outcomes and complications.
Main Results:
- A patient previously treated with EVAR experienced abdominal endograft proximal collapse.
- The patient also presented with acute type A aortic dissection.
- This combination represents a rare clinical scenario.
Conclusions:
- Abdominal endograft proximal collapse is a rare complication of EVAR.
- Simultaneous occurrence with acute type A aortic dissection presents unique management challenges.
- Careful patient selection and surveillance are crucial after EVAR.

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...

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...

01:15Aortic Regurgitation I: Introduction
444
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...

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...
