Infra-renal aortic stenosis is where the narrowing of the blood vessel in the abdomen occurs below the level of the kidneys. This condition involves the constriction of the main artery responsible for carrying oxygen-rich blood from the heart to the lower body. It occurs when the aortic artery narrows due to the accumulation of plaque or calcification, impeding the smooth flow of blood. Left untreated, it can increase the risk of complications such decreased lower limb perfusion or gangrene.

Stenting is a commonly used treatment modality for infra-renal aortic stenosis. During the procedure, a thin, expandable tube called a stent is inserted into the narrowed section of the aorta. The stent acts as a scaffold, widening the artery and restoring proper blood flow to the lower body. This minimally invasive approach offers several advantages over traditional open surgery, including reduced hospitalization time, quicker recovery, and lower risk for high-risk patients.
