    Anastomotic aneurysms (AA) after arterial reconstruction, often linked to suture issues and arterial wall degeneration, require surgical repair. Early elective repair using Dacron grafts is recommended to prevent complications and recurrence.

    Area of Science:

    • Vascular Surgery
    • Surgical Innovation
    • Graft Complications

    Background:

    • Anastomotic aneurysms (AA) following arterial reconstruction present significant surgical challenges.
    • Previous reconstructions frequently utilized Dacron grafts and braided Dacron sutures.

    Observation:

    • Analysis of 29 nontraumatic AA in 24 patients revealed common indications for repair including expansion/rupture, graft occlusion, and aortoenteric fistula.
    • Suture line dehiscence due to arterial wall attenuation was the predominant operative finding.

    Findings:

    • Partial excision and revascularization with interposition Dacron grafts, typically to the profunda femoris artery, were performed in most cases.
    • Two of three postoperative deaths occurred in patients with aortoenteric fistulas.
    • No immediate limb loss or recurrences were observed with the described surgical approach.

    Implications:

    • Structural degeneration of the native artery is a key factor in AA development.
    • Key principles for uninfected AA repair include controlled inflow/outflow, limited dissection, and interposition grafting.
    • Early elective repair is crucial to avoid graft occlusion and complications associated with large aneurysm repair.
