Summary
Epithelioid angiosarcoma developed in the abdominal aortic wall following endovascular aneurysm repair (EVAR). Despite surgical intervention, the rare cancer progressed, leading to peritoneal metastasis and patient death.
Area of Science:
- Vascular Surgery
- Surgical Oncology
- Pathology
Background:
- Endovascular aneurysm repair (EVAR) is a common treatment for abdominal aortic aneurysms.
- Graft infection is a known complication following EVAR.
- Epithelioid angiosarcoma is a rare and aggressive vascular malignancy.
Observation:
- A 60-year-old male presented with symptoms suggestive of graft infection 7 years after EVAR.
- Initial treatment involved endograft removal and Dacron graft implantation.
- Post-operative imaging revealed a growing periaortic mass and abdominal nodules.
Findings:
- Histological examination confirmed epithelioid angiosarcoma of the abdominal aortic wall.
- The angiosarcoma had metastasized to the peritoneum.
- Despite further surgery, the patient succumbed to the disease.
Implications:
- This case highlights a rare but devastating complication of EVAR.
- Epithelioid angiosarcoma should be considered in the differential diagnosis of perigraft masses after EVAR.
- Aggressive surgical and oncological management may be required for this rare malignancy.

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.

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...

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...
