Summary
Managing arteriovenous fistula pseudoaneurysms in hemodialysis patients requires complex surgical repair. This case shows a successful individualized approach preserving vascular access and quality of life.
Area of Science:
- Vascular Surgery
- Nephrology
- Interventional Radiology
Background:
- Pseudoaneurysms at arteriovenous fistula (AVF) sites threaten hemodialysis access patency.
- Management is complex in patients with prior AVF failures and thromboses.
Purpose of the Study:
- To describe the successful surgical management of a large pseudoaneurysm in a patient with end-stage renal disease and multiple AVF failures.
- To highlight the importance of tailored surgical techniques for preserving vascular access.
Main Methods:
- A 27-year-old patient with end-stage renal disease presented with a large AVF pseudoaneurysm.
- Diagnosis was confirmed by duplex ultrasound.
- Surgical management involved pseudoaneurysm excision, collateral vein mobilization, and complex anastomoses to ensure outflow.
Main Results:
- The patient's postoperative course was uneventful.
- Hemodialysis via the reconstructed AVF resumed after 2 months and remained functional for over 18 months.
- No complications or limitations were reported post-surgery.
Conclusions:
- Individualized and complex surgical strategies are crucial for managing AVF pseudoaneurysms.
- Timely, tailored interventions can successfully preserve vascular access and maintain patient quality of life, even in challenging cases.

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...

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

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...
