Percutaneous Epidural Adhesiolysis for Chronic Low Back Pain

September 27, 2018 Medical Technology Directory

Health Problem: Chronic low back pain (CLBP) is a common health condition that can cause substantive disability. There are many causes of CLBP, including spinal stenosis, disc disorders, and disc degeneration. Patients who have enduring low back pain even after surgery (e.g., laminectomy) are said to have failed back surgery syndrome (FBSS). Percutaneous epidural adhesiolysis was designed to lyse epidural scarring in patients with CLBP and leg pain due to lumbar FBSS. In the literature, percutaneous adhesiolysis (PA) has been more generally used for patients with CLBP with or without radiculopathy or sciatica that has not responded adequately to noninterventional...

Comparative Effectiveness Review of Transcatheter Aortic Valve Implantation (TAVI) and Surgical Aortic Valve Replacement (SAVR) for Aortic Stenosis in Lower Risk Patients

September 27, 2018 Medical Technology Directory

Health Problem: Aortic stenosis (AS) is the most common cause of aortic valve disease in older patients; approximately 7% of the population > 65 years of age is affected. The prevalence of AS is approximately 0.4% among adults aged ≥ 18 to 75 years in the United States. At younger ages, AS is most often related to bicuspid aortic valve but in older patients, AS is related to degenerative disease. Moderate or severe AS occurs in patients aged ≥ 75 years with a prevalence of 2.8%. The overall incidence and prevalence of AS has increased with the aging population. Technology Description:...

Transcutaneous Electrical Nerve Stimulation for Chronic Low Back Pain

September 21, 2018 Medical Technology Directory

Health Problem: Chronic low back pain (CLBP) can be defined as low back pain (usually, in the L1-L5 vertebrae in the lumbar region) that persists ≥ 12 weeks, even after treatment of the initial injury or underlying cause of acute low back pain. Low back pain impairs people’s physical and psychological health and their ability to work and take care of their family and social responsibilities. In the United States, an estimated 13% of adults 20 to 60 years of age have CLBP. Technology Description: Transcutaneous electrical nerve stimulation (TENS) devices comprise a small, programmable, electronic stimulus generator and ≥ 1...

Comparative Effectiveness Review of Mandibular Advancement Devices for Sleep Apnea: A Review of Reviews

September 20, 2018 Medical Technology Directory

Health Problem: Obstructive sleep apnea (OSA) is a chronic disorder that is characterized by repeated starting and stopping of breathing during sleep. Patients with OSA typically exhibit loud snoring followed by periods of silence and then snorting, choking, or gasping upon continuation of breathing. This often leads to fragmented sleep and daytime sleepiness. The estimated prevalence of moderate-to-severe OSA is 10% of men and 3% of women younger than 50 years of age and 17% of men and 9% of women older than 50 years of age. Technology Description: Mandibular advancement devices (MADs) are the most common type of oral appliance...

September 19, 2018 Medical Technology Directory

Health Problem: Nausea is a subjective phenomenon of an unpleasant sensation in the epigastrium and back of the throat that may or may not progress to vomiting. Vomiting is the forceful expulsion of the contents of the stomach, duodenum, or jejunum through the mouth. Three causes of nausea and vomiting that acupuncture has been investigated for the treatment of include pregnancy, cancer treatment, such as chemotherapy and radiotherapy, and surgery. Technology Description: The technique of acupuncture involves percutaneous insertion of very fine needles to a depth of approximately 10 to 15 millimeters at prescribed acupoints. In some cases, low-voltage current is...
