Summary
Surgical closure of traumatic arteriovenous fistulas (AVFs) is effective. Excision and reconstruction led to successful outcomes in most patients, though some experienced persistent symptoms after treatment for these complex vascular injuries.
Area of Science:
- Vascular Surgery
- Trauma Surgery
Background:
- Traumatic arteriovenous fistulas (AVFs) present significant surgical challenges.
- Delayed presentation and lack of initial reconstructive surgery were common in treated patients.
Observation:
- The dominant clinical sign of AVFs was a pulsating tumor with a thrill.
- A mean of 13.3 years elapsed between trauma and surgical fistula closure.
Findings:
- Excision and reconstruction of the affected artery and vein successfully closed the fistula in 11 out of 14 patients.
- Ligation alone in 3 patients resulted in early shunt recurrence.
- Postoperative follow-up (3-15 years) confirmed fistula closure in all cases, with 5 patients reporting moderate residual symptoms.
Implications:
- Surgical excision and reconstruction represent a definitive treatment for traumatic arteriovenous fistulas.
- While effective, surgical management may not fully resolve all symptoms in every patient.
- Understanding the long-term outcomes of AVF treatment is crucial for patient management and surgical planning.
