Renal arterial occlusion occurs when a thrombus or embolism (blood clot or cholesterol plaque) breaks free and blocks the arteries leading to one or both kidneys.
Symptoms of an acute renal arterial occlusion may include:
- hypertension
- fever
- sudden pain in the lower back or flank
- nausea and vomiting
- protein and/or blood in the urine
An individual with renal arterial occlusion may have no overt symptoms, particularly if only one kidney is affected or if the blockage is only partial. Health problems from secondary complications such as chronic kidney failure may be the first indication that something is wrong.
