Hydrophilic polymer embolization: another differential diagnosis of iatrogenic leg embolization after transcatheter aortic valve replacement.
In daily practice, the iatrogenic complication hydrophilic polymer embolization (HPE) is under-recognized. An 86-year-old male experienced a distal foot embolization after transcatheter aortic valve replacement. Rashes appeared only in the access side foot just after the procedure. Gradual worsening of the rashes was first thought to be cholesterol crystal embolization (CCE), but a pathological examination revealed HPE. The clinical course following the diagnosis was uneventful without notable treatment. We experienced a rare but important alternative differential diagnosis of CCE after catheter intervention.
