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.

Acute renal infarction is very dangerous, early diagnosis is essential for early and long-term intervention, thereby helping to preserve kidney function. Although non-specific, the very common symptom of lower back pain can still be the first warning sign of acute renal infarction.
