Lab Tests and Procedures for Diagnosis of Stenosis

The following lab tests and procedures are used to detect Stenosis:
  • X-ray: To see the bony changes
  • Medical genetics: To produce cross-sectional images of the spine
  • CT scan (Computerised tomography): To see the detailed cross-sectional images of body
  • Blood test: To measure the cholesterol levels, renin and aldosterone levels, BUN, creatinine and potassium levels in the blood
  • Doppler ultrasound: To find the renal arteries blockages
  • MRA (Magnetic resonance angiography): MRA uses radio waves and strong magnetic fields to produce detailed 3-D images of the renal arteries and kidneys
  • Renal arteriography: To find the blockage in the renal arteries

Complications of Stenosis if untreated

Yes, Stenosis causes complications if it is not treated. Below is the list of complications and problems that may arise if Stenosis is left untreated:
  • numbness
  • weakness
  • balance problems
  • incontinence
  • paralysis
  • aortic aneurysm
  • heart attack
  • heart failure
  • chronic kidney disease
  • stroke
  • vision problems
  • poor blood supply to the legs

Procedures for Treatment of Stenosis

The following procedures are used to treat Stenosis:
  • Surgery: Removal of lamina of the affected vertebrae and vertebrae in the neck to relieve the pressure on the spinal cord
  • Nephrectomy: To resolve systemic hypertension without compromising renal function
  • Renal artery bypass surgery: To create an alternate route for blood to flow around a blockage in the renal arteries
  • Renal angioplasty and stenting: To treat renal artery stenosis

Self-care for Stenosis

The following self-care actions or lifestyle changes may help in the treatment or management of Stenosis:
  • Apply hot or cold packs: Help relieving the symptoms of cervical spinal stenosis
  • Follow healthy diet: Reducing excess weight can decrease load-bearing stress on the lumbar spine
  • Maintain a healthy weight: Help to lower the blood pressure
  • Restrict salt in the diet: To reduce blood pressure
  • Be physically active: Being physically active on a regular basis may help to lose weight, lower the risk of heart disease, lower the cholesterol and lower blood pressure
  • Reduce stress: Stress can increase the blood pressure temporarily
  • Avoid alcohol: Too much alcohol may increase blood pressure
  • Don't smoke: Tobacco causes injuries to blood vessel walls

Alternative Medicine for Treatment of Stenosis

The following alternate medicine and therapies are known to help in the treatment or management of Stenosis:
  • Physical therapy: Build up strength, flexibility and stability of the spine
  • Chiropractic treatment: Helpful in restoring the normal spinal movement
  • Acupuncture: Stimulates the certain places on the skin to relieve the pain

Time for Treatment of Stenosis

While time-period of treatment for each patient may vary, below is the typical time-period for Stenosis to resolve if treated properly under an expert supervision:
