Recurrent coil migration after treatment of traumatic pseudoaneurysm: A case report
Abstract
Introduction: Coil migration (CM) is an extraordinary delayed complication associated with coil embolization as the definitive treatment for pseudoaneurysm (PA). Our case is a recurrent one with episodes occurring in approximately 2-year intervals. Case presentation: A teenager presented with a PA after a car accident in 2014. He was admitted and treated with stent-assisted coils at our institution. The patient experienced delayed coil migration into the nostril in 2017 which we resolved by cutting off the migrated coils under nasal-endoscopy. The remaining coils migrated into the oral cavity in 2019 and were completely pulled out under nasal-endoscopy. Conclusion: When a patient experienced CM in vitro, it is advocated that, the extruding coils be cut off while the remaining coils are left in-situ. As much as possible, coil should not be forcefully pulled out. Keywords: Recurrent, Pseudoaneurysm, Coil migration, Endovascular
