Pulmonary Artery Coil: Unexpected Expectorated Foreign Body

Unexpected Complications 25 Years after Coil Embolization for Pulmonary Arteriovenous Fistula

“…Endobronchial coil migration as a long-term complication is rare, with only 13 reported cases (Table 2) (1,(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). In 7 of the 13 patients, coil migration occurred more than a year after coil embolization, with a median period of 2.3 (1.2-12) years.…”

Endobronchial Migration of a POD Packing Coil Following Embolization of a Pulmonary Artery Pseudoaneurysm

“…Endovascular coil embolization is an accepted method for the treatment of pseudoaneurysms with excellent success rates. 1 Coil migration is a well-documented postembolization complication in endovascular procedures, with varying rates of occurrence (neurovascular procedures: 2-6%; few cases have been reported with bronchial artery embolization, 2 and less than five cases have been published with pulmonary artery embolization of pseudoaneurysms [3][4][5][6] ). Depending on the structure the coil migrates into, it can have differing outcomes ranging from tissue hypoperfusion (parenchymal ischemia) from occlusion of nontarget vessels to massive hemorrhage and potential fatality from rupture or instrumentation trauma to the pseudoaneurysm.…”

Bronchoscopy-guided removal of intrabronchial coil migration after coil embolization of pulmonary arteriovenous malformation

“…Although few cases of coil migration from pulmonary AVMs have been reported [ 13 , 14 ], coil migration after embolotherapy for other lung pathologies have also been documented. Cases include intrabronchial migration after coil embolization of pulmonary arterial aneurysms [17] and pseudoaneurysms [18] as well as from bronchial artery embolization [19] . Coil migration from pulmonary embolization can also cause more serious complications, such as fistulization [20] , migration to the heart [ 11 , 21 , 22 ], pulmonary hypertension [11] , pneumothorax [23] , erosion into the bronchus [15] , and migration into the contralateral pulmonary vasculature [22] .…”
