Fatal Hemorrhage from Kidney after Endovascular Repair for Chronic Type B Dissection Complicated with Disseminated Intravascular Coagulation.

We report lethal hemorrhage from the kidney after thoracic endovascular repair for chronic type B dissection complicated by disseminated intravascular coagulation (DIC). A 70-year-old woman underwent thoracic endovascular repair to treat chronic DIC. Two weeks after surgery, refractory shock suddenly occurred and computed tomography showed a massive hematoma around the left kidney. Emergent renal artery angiography showed multiple bleeding points in the renal cortex. Immediate embolization of the renal artery was performed and her hemodynamic condition recovered. Physicians should be aware that massive hemorrhage from visceral organs is possible during the perioperative period of endovascular intervention for treatment of DIC.
