Kidney infarction

Kidney infarction is a serious condition that can be caused by various reasons, such as atherosclerosis, hypertension, diabetes, rheumatoid arthritis. It is important to know the symptoms in order to consult a doctor in time and avoid the development of serious complications.

Renal infarctions occur as a result of occlusion

– acute disturbance of the blood supply to the kidneys, manifested by necrosis of renal tissue and varying degrees of renal dysfunction within several hours.

A typical picture of renal infarction in projection angiography is in the form of a high amniotic peripheral concavity (type A). Unlike dissecting abdominal aortic aneurysm, renal artery infarction is accompanied by dilation of the distal renal vessels.

Using angiography, you can determine the severity of blockage of the renal vessels and detect signs of renal-hepatic arterial compression. In case of malformations and anomalies in the functioning of the kidneys with pronounced dilatation of the renal sinus veins in patients with diabetes mellitus, it is necessary to exclude the possibility of developing venous thromboembolism. Kidney infarctions most often occur in men aged 40 to 60 years, usually after repeated episodes of renal colic or after exacerbation of chronic pyelonephritis.

The prognosis for renal artery infarction is serious. Even with timely medical care, in most cases the disease has an unfavorable outcome for the kidney: the probability of permanent loss of kidney function is from 15 to 70%.
