Renal subcapsular hematoma after cardiac catheterization.

Vascular complications occur during and after cardiac catheterization, with hematoma formation over the access site being the most frequently seen. Hematomas secondary to cardiac catheterization include retroperitoneal, intraperitoneal, groin or thigh and abdominal wall hematomas. A 53 year-old male underwent emergent percutaneous coronary intervention for an acute myocardial infarction. A few hours later, a subcapsular hematoma developed over the left kidney, and he was successfully managed supportively with parenteral fluids and blood transfusion. To the best of our knowledge, this is the first report of a subcapsular hematoma developing after cardiac catheterization in the English literature.
