Renal artery thrombosis is caused by the rupture of atherosclerotic plaques. Immune response to foreign substances will occur after embolism leading to impaired renal function in 3-8 weeks. In case of large thromboembolism or recurrent episodes of embolism, the patient will have acute renal failure.

Renal artery thrombosis and renal embolism are vascular events that occur in the kidney. Similar to arterial thrombosis in other organs, thrombosis leading to complete renal artery occlusion will cause irreversible loss of kidney function if diagnosed late and intervened incorrectly from the beginning.
