Management of giant venous aneurysms secondary to arteriovenous fistula in hemodialysis patients
Abstract
Objective: An aneurysmal fistula can continue to provide hemodialysis access for along time, but giant aneurysms should be operated on to prevent complication. The purpose of this study was to describe our experience of the surgical management of giant venous aneurysms that have developed as a complication of dialysis access.
Methodology: Twenty patients with giant venous aneurysms of the AVF underwent surgical procedures at our hospital from December 2003 to December 2010. The diagnoses were made by physical examination and Color Doppler Ultrasonography.
Results: There were 12 male and 8 female patients ranging in age from 29 to 68 years with a mean age of 44.6±12.3 years. Plication of the aneurysmal dilatations was performed in 17 patients. In two patients, aneurysmal dilatations were excised with restoration of the artery. The remaining one patient who received a successful renal transplantation was also associated with brachial artery aneurysm. Venous aneurysmal dilatations were excised and arterial aneurysms were repaired. All patients experienced a marked decrease in the size of venous dilatations. There were no vascular complications during the follow-up period.
Conclusion: We suggest that plication is safe and effective in controlling venous dilatation and achieving patency. Reinforcing the suture line using an external mesh may not be required. However, prospective randomized studies will be required to assess the long-term outcomes.
