Arteries are basically responsible for carrying blood to the kidney.

It is believed that kidneys are having sensitive nature, especially when blood flows through them. The disorder may lead to impaired functioning of kidneys if any reduction regarding blood flow through renal artery takes place. Moreover, if the condition persists for a long period of time, then permanent kidney failure chances become more acute. Any injury of trauma to the back or abdomen results in acute arterial occlusion of the kidney. People who are suffering from certain heart disorders such as atrial fibrillation, mitral stenosis, etc are more prone towards risk of emboli. In addition to this, condition of renal artery embolism greatly affects those individuals in which chances of forming clots are high.

Conservative Modern Medicine

In most of the cases, people require no specific treatment as acute arterial occlusion of the kidney gets better with the passage of time. Treatment like attempts of opening the artery is basically given when functional kidneys get affected or in the case when blockage gets discovered within short span of its occurrence. Clot dissolving medications and Coumadin medication (prevent blood from clotting) are given in attempts to open the artery. In some severe cases, artery needs to be repaired either surgically or by inserting a tube, referred as catheter, into the artery.
