  • Title: Novel repair of venous aneurysms secondary to arteriovenous dialysis fistulae.
    Author: Pierce GE, Thomas JH, Fenton JR.
    Journal: Vasc Endovascular Surg; 2007; 41(1):55-60. PubMed ID: 17277244.
    Abstract:
    This report describes the surgical management of 12 hemodialysis patients with arteriovenous fistulae in whom non-infected, fusiform venous aneurysms developed that compromised access for dialysis. The venous aneurysmal changes were too extensive to permit excision and primary veno-venous anastomosis. To avoid the use of synthetic interpositional grafts, the venous aneurysms were left in situ and reduced in size to match the diameters of the veins entering and exiting the aneurysms. After decompression, the lumens of the venous aneurysms were reduced by firing staple lines along the longitudinal axes of the venous aneurysms and excision of the aneurysmal tissue anterior to the staple lines. Twenty-eight aneurysms were repaired by this method of reduction aneurysmoplasty, in 15 operations on 12 patients over the past 10 years. There were no wound infections or dehiscences and no bleeding or hematomas. After the operations, the arteriovenous fistulae were used continuously for hemodialysis until the patients died (7 patients for 36 months -/+ 28 SD), were lost to follow-up (1 patient at 30 days postoperatively), until the arteriovenous fistulae thrombosed following revision of the arteriovenous anastomosis (1 patient at 41 months postoperatively), or until the arteriovenous fistulae was ligated to relieve pain in the upper arm (1 patient at 6 months postoperatively). Two patients continue to use their arteriovenous fistulae until and including the time of this report at 10 and 11 months, respectively. Reduction aneurysmoplasty as described in this report offers an effective and low-risk option for the management of venous aneurysms secondary to arteriovenous fistulae in hemodialysis patients.
