Nosebleeds, or epistaxis (hemorrhaging from the nose), is a common medical condition, with approximately 60% of the adult population having experienced at least one episode during their lives. Fortunately, most cases resolve with conservative methods; however, there are rare times when epistaxis cases require medical attention. When medical interventions such as cauterization are not effective, interruption of the blood supply can be performed by embolization. Interventional Neuroradiologists guide small catheters into the small arteries suppling the mucosa of the nose and block them with particles. This helps to reduce and in most cases stop the nose bleeds.
Vertebroplasty and Kyphoplasty
Vertebroplasty and kyphoplasty are minimally invasive procedures for the treatment of painful vertebral compression fractures (VCF), which are fractures involving the vertebral bodies that make up the spinal column. VCFs are a common result of osteoporosis.
Typically, vertebroplasty and kyphoplasty are recommended after less invasive treatments, such as bed rest, a back brace or pain medication have been ineffective. Vertebroplasty and kyphoplasty can be performed immediately in patients with problematic pain requiring hospitalization or for conditions that limit bed rest and pain medications.
During vertebroplasty and kyphoplasty procedures, after the skin has been numbed with local anesthetic, the Interventional Neuroradiologist will use imaging guidance to pass a trocar through the skin and into the fractured vertebral body so that a cement mixture can be injected into the vertebra. In kyphoplasty, a balloon tamp can be inserted first and then inflated to create a cavity for cement injection.
A lumbar puncture (also called a spinal tap) is a minimally invasive, image-guided diagnostic test that involves the removal of a small amount of cerebrospinal fluid (CSF)—the fluid that surrounds the brain and spinal cord—or an injection of medication or other substance into the lumbar (or lower) region of the spinal canal.
Guided by real-time x-ray images (fluoroscopy), the Interventional Radiologist will insert the needle through the skin between two lumbar vertebrae and into the spinal canal. Once the needle is in place, a small amount of CSF is removed and the spinal pressure is measured. After the needle is removed, you may be asked to lie on your back or side for a few hours. However, the procedure itself is usually completed within 45 minutes.
