Abstract
ABSTRACT
Different hydrophilic and hydrophobic polymers are used as lubricious coatings to reduce vascular traumas in minimally invasive percutaneous procedures. Although they are usually very safe, there is still a risk of serious complications in patients undergoing such procedures, mostly derived from the devices' coating detachment and systemic embolization. The lungs are the most common organ involved, followed by the central nervous system. Yet, cutaneous embolization is unusual, and only 19 cases are available in the literature. Most commonly, they present as asymptomatic retiform purpura on the lower legs, which tends to involve spontaneously. Correct clinical diagnosis is not suspected in most cases, being cholesterol emboly or vasculitis the preferred options. Time interval since surgical procedure and appearance of lesions vary widely but they generally start in the first few days. Histopathological identification of the embolus as bluish, amorphous intraluminal material in dermal vessels is diagnostic, but vasculitic signs are not present. We report 2 cases of skin lesions as the main manifestation of polymer embolization after endovascular surgical procedures. In both cases, biopsy allowed identification of embolized foreign material and lesions resolved without specific treatment.
