(2) secondary trauma: renal pedicle of blunt trauma;The aorta or renal arteriography;Percutaneous via cavity renal artery balloon expansion;Renal artery revascularization.Embolism in renal transplant recipients.

(1) the heart embolus: atrial fibrillation;Artificial heart valves.After myocardial infarction, mural thrombus;Left atrial myxoma.
(2) the heart outside embolus: adipose embolus;Tumor emboli.Venous emboli by room or ventricular septal defect into the artery.
