Cutaneous microemboli from hydrophilic polymer after endovascular procedures

Hydrophilic polymer gel coatings in endovascular devices can embolize to skin and cause microvascular occlusion, presenting as livedo racemosa, purpura, or both. Given the number of patients observed over a short period, this phenomenon may be underappreciated. Hydrophilic polymer gel emboli should be considered in differential diagnosis of livedo racemosa and purpura after endovascular procedure.
