Stenosis

Stenosis refers to an abnormal narrowing or constriction of a bodily passage, such as a blood vessel, a valve, or a canal. This narrowing obstructs the flow of fluids or other substances through that passage, leading to various health complications depending on the location and severity of the constriction. The degree of stenosis can range from mild, causing minimal disruption, to severe, potentially life-threatening blockages requiring immediate medical intervention. The term applies to various body systems and organs.

Stenosis meaning with examples

• The patient’s coronary artery stenosis significantly reduced blood flow to the heart muscle. Tests revealed the narrowing was caused by plaque buildup, restricting oxygen delivery. Consequently, the patient experienced chest pain and fatigue, indicating the severity of the condition and the need for intervention to alleviate the blockage and avoid heart damage.
• The doctor diagnosed aortic valve stenosis, hindering the heart's ability to pump blood efficiently. The narrowed valve caused the heart to work harder, leading to shortness of breath and eventually heart failure. The doctor decided on valve replacement surgery to restore proper blood flow and prevent further deterioration. This decision aimed to correct the heart's function.
• The patient with spinal stenosis experienced excruciating pain and numbness in her legs. The narrowing of the spinal canal, due to age-related changes, compressed the spinal cord. Consequently, mobility was severely limited, requiring physical therapy and medication for pain management. Eventually, surgery was considered to decompress the affected nerves to relieve the pain.
• The ureteral stenosis obstructed the flow of urine from the kidney to the bladder. The narrowing resulted in kidney swelling and pain, causing repeated urinary tract infections. Doctors implemented treatments to widen the narrowed ureter through minimally invasive procedures, to improve kidney function and prevent further complications. Prompt care provided relief.
