Coil Migration to Pulmonary Vasculature: Case Report and Review

Coil migration to systemic circulation during coil embolization is a rare and potentially fatal complication. We present a case of asymptomatic coil migration to a pulmonary artery during embolization of accessory veins to salvage an Arteriovenous Fistula (AVF). The patient was managed conservatively and has remained asymptomatic after one and half years of follow up. We also identified the available literature for coil migration to the cardiopulmonary system and conducted a review pertaining to the symptom profile, factors predisposing to migration, management and long term complications.
