Hydrophilic Polymer Embolization after Thoracic Endovascular Aortic Repair

Hydrophilic polymer embolization is a rare complication after endovascular procedures that is currently underappreciated. Present understanding on this phenomenon relies on sparse case reports with histologic evidence of foreign polymers in end-organ tissue. Here, we report two deaths associated with hydrophilic polymer embolization after complex thoracic endovascular aortic repair.
