Vertebral arteriovenous fistula as a result of Swan-Ganz catheter insertion: surgical correction in a symptomatic patient.
A case of a vertebral arteriovenous fistula is reported after being caused by insertion of a Swan-Ganz catheter into the vertebral artery prior to cardiac surgery. The patient's clinical symptoms which precipitated re-admission consisted of multiple episodes of diaphoresis and dizziness. A right carotid bruit was detected in the neck. Four vessel cerebral arteriograms could not accurately identify the origin of the fistula. The proximal carotid artery was considered by several radiologists to be the arterial source of the fistula. During the surgical procedure, a tortuous right vertebral artery was found to be the source of the fistula. Surgical correction of the fistula was successful with preservation of the vertebral artery. Recommendations from a review of the literature are made for the current treatment of this rare complication from an insertion of a Swan-Ganz catheter.
