Embolization For Renal Hemorrhage Research Articles

Embolization of Renal Hemorrhage in Pregnancy

Selective embolization in pregnancy for treatment of renal hemorrhage has been reported infrequently in the literature; the possibility of minimizing radiation dose to the fetus by using dose-sparing fluoroscopy techniques is not commonly appreciated by the obstetric community. We describe performing partial renal embolization with the use of all available radiation dose-sparing techniques. The patient had no further complications, and she and her newborn were well postpartum. A dose reconstruction indicated that the fetal dose from the procedure was less than 5 mGy. When faced with a symptomatic renal hemorrhage in pregnancy, a renal angiogram and embolization by an experienced interventional radiologist are effective treatment options that can be performed with minimal fetal radiation risk.

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.
