Superselective embolization of renal hemorrhage occurring after percutaneous coronary intervention.

A 69-year-old female was hospitalized for acute coronary syndrome and received full antiplatelet and anticoagulant therapy. The patient underwent angioplasty and stent implantation on right coronary and left circumflex arteries with good angiographic result. After the procedure, the patient developed hemorrhagic shock due to massive left renal hemorrhage. An emergent digital subtraction angiography showed bleeding from a left segmental renal artery. The hemorrhage was successfully managed with transcatheter superselective embolization. The patient was discharged after 22 days in good general condition with normal renal function. One-year follow-up was uneventful.
