Epidural Blood Patch . The epidural space is not an injection into the spinal cord itself. The spinal cord and spinal nerves are in a “sack” containing clear fluid (cerebrospinal fluid). The area outside this “sack” is called the epidural space. Why is it done? There are certain conditions under which patients will have had injections in the spinal column. Examples include an epidural during labor, a diagnostic spinal tap, a therapeutic spinal injection, etc. A small number of patients will experience a severe headache after the procedure, usually worse with standing and better when lying down. This is due to a persistent leak of spinal fluid into the epidural space. Although the headache itself is harmless, it can be very severe and very debilitating. Your doctor may ask you to come to our clinic for an “epidural blood patch”. The injection of a freshly drawn sample of your own blood into the epidural space “plugs the leak” and the headache goes away. A spinal tap is a procedure. The actual injection takes only a few minutes. Please allow about an hour and a half for the procedure; this will include talking to your doctor before the procedure, signing the informed consent, positioning in the room, and observation by the recovery room nurse afterwards. What medicines are injected? There is local anesthetic to numb the skin and any sedatives that you may need. Will it hurt? All of our procedures begin by injecting a small amount of local anesthetic through a very small needle. The patch helps restore normal pressure. An epidural blood patch is a treatment for a post. Cerebrospinal Fluid Leaks. An epidural blood patch is used in patients with spinal. The overwhelming majority of spontaneous leak patients have a spinal. A CSF leak is an escape of the fluid that surrounds the brain and. This is called a blood patch. Most CSF leaks are a complication of a spinal tap or surgery. Treatments for spinal CSF leaking. A favorable response to an epidural blood patch supports the diagnosis of a leak but. Spinal tap (lumbar puncture) Sometimes. Depending on the cause of the leak. This is called a blood patch. It feels like a little pinch and then a slight burning as the local anesthetic starts numbing the skin. After the skin is numb, the procedure needle feels like a bit of pressure at the injection site. If you wish you can have intravenous sedation or something by mouth prior to the procedure. Will I “be asleep” for this procedure? This choice is yours. You can also choose to have IV sedation, which can keep you very comfortable. It can range from some drowsiness or you may have little or no memory of the procedure depending upon your comfort level, regardless of the amount of sedation, you must not eat or drink anything for 6 hours prior to this and you must also have a driver when choosing sedation. It is OK to take your medications with a sip of water with either decision. It is typically done with you lying on your stomach. Your blood pressure and oxygen levels will be monitored. In addition to your doctor and the x- ray technician, there will be a nurse in the room at all times. The skin on the back is cleaned with antiseptic solution. A separate area where a good vein is available is also cleaned with antiseptic solution. A small intravenous catheter is placed in the vein. After your doctor has placed the epidural needle near the affected area, he will draw about 2. What should I expect after the injection? Immediately after the injection, you may feel pressure in the back. This is due to the effect of the blood in the epidural space. After resting for about 3. Typically, most patients experience significant relief immediately. After a few hours, your body will have had a chance to replenish the lost spinal fluid and your headache should continue to get better. What should I do after the procedure? We advise patients to take it easy for a day or so after the procedure. You should rest for the first day, you do not have to lay completely and bathroom visits are permitted. Your recovery room nurse will advise you about your activities after going home. Can I go back to work the same day or the next day? You should not go back to work the same day. By the next day, most patients will be able to although you might need an extra day to recover. How long does it last? The epidural blood patch is permanent. After the injection of your blood, the body’s own healing system should take over and finish repairing the spinal fluid leak. A small number of patients (usually less then 1. What are the risks and side effects? Overall, this procedure has very few risks. However, as with any procedure, there are some risks and side effects you should know about. Commonly encountered side effects are increased pain from the injection (usually temporary), rarely inadvertent puncture of the“sack” containing spinal fluid (may not relieve your headaches), infection, bleeding, nerve damage, or no relief from your headache. Who should not have this injection? The following patients should not have this injection: if you are allergic to any of the medications to be injected, if you are on a blood- thinning medication (e. Spontaneous cerebrospinal fluid leak - Wikipedia, the free encyclopedia. Spontaneous cerebrospinal fluid leak syndrome (SCSFLS) is a medical condition in which the cerebrospinal fluid (CSF) held in and around a human brain and spinal cord leaks out of the surrounding protective sac, the dura, for no apparent reason. The dura, a tough, inflexible tissue, is the outermost of the three layers of the meninges, the system of meninges surrounding the brain and spinal cord. A spontaneous cerebrospinal fluid leak is one of several types of cerebrospinal fluid leaks and occurs due to the presence of one or more holes in the dura. A spontaneous CSF leak, as opposed to traumatically caused CSF leaks, arises idiopathically. A loss of CSF greater than its rate of production leads to a decreased volume inside the skull known as intracranial hypotension. A CSF leak is most often characterized by orthostatic headaches . Other symptoms can include neck pain or stiffness, nausea, vomiting, dizziness, fatigue, and a metallic taste in the mouth (indicative of a cranial leak), among others. A CT scan can identify the site of a cerebrospinal fluid leakage. Once identified, the leak can often be repaired by an epidural blood patch, an injection of the patient's own blood at the site of the leak, fibrin glue injection or surgery. SCSFLS afflicts 5 out of every 1. On average, the condition is developed at the age of 4. Some people with SCSFLS chronically leak cerebrospinal fluid despite repeated attempts at patching, leading to long- term disability due to pain. SCSFLS was first described by German neurologist Georg Schaltenbrand in 1. American physician Henry Woltman of the Mayo Clinic in the 1. Classification. In some of these cases, CSF can be seen dripping out of the nose. For this reason SCSFLS is referred to as CSF hypovolemia as opposed to CSF hypotension. This is known as second- half- of- the- day headache. This may be an initial presentation of CSF leak or appear after treatment and likely indicates a slow CSF leak. The lower portion of the brain is believed to stretch or impact one or more cranial nerve complexes, thereby causing a variety of sensory symptoms. Nerves that can be affected and their related symptoms are detailed in the table at right. However these patients do not exhibit any other Marfan syndrome presentations. The increased pressure causes a rupture of the cranial dura mater, leading to CSF leak and intracranial hypotension. As holes form in the spinal dura mater, CSF leaks out into the surrounding space. The CSF is then absorbed into the spinal epidural venous plexus or soft tissues around the spine. Incorrect diagnoses include migraines, meningitis, Chiari malformation and psychiatric disorders. The average time from onset of symptoms until definitive diagnosis is 1. The use of CT, MRI, and assays are the most common types of CSF leak instrumental tests. Many CSF leaks do not show up on imaging and chemical assays, thus such diagnostic tools are not definitive to rule out CSF leaks. A clinician may often depend upon patient history and exam to diagnose, for example: discharge of excessive amount of clear fluid from the nose upon bending over, the increase in headache following a Valsalva maneuver or the reduction of headache when the patient takes a prone position are positive indicators. Clinical exam is often used means to diagnose CSF leaks. Improved patient response to conservative treatment may further define a positive diagnosis. The lack of clinician awareness of the signs - symptoms and ailments- of a CSF leak is the greatest challenge to proper diagnosis and treatment, in particular: the loss of the orthostatic characteristic of headache and that every chronic CSF leaker will have a unique symptom set that as a whole contributes to the underlying condition, and diagnosis of, a CSF leak. Diagnosis of a cerebrospinal fluid leak is performed through a combination of measurement of the CSF pressure and a computed tomographymyelogram (CTM) scan of the spinal column for fluid leaks. Once the pressure is measured, radiopaque contrast material is injected into the spinal fluid. The contrast then diffuses out through the dura sac before leaking through dural holes. This allows for a CTM with fluoroscopy to locate and image any sites of dura rupture via contrast seen outside the dura sac in the imagery. MRI studies may show pachymeningeal enhancement (when the dura mater looks thick and inflamed), sagging of the brain, pituitary enlargement, subdural hygromas, engorgement of cerebral venous sinuses, and other abnormalities. However, patients with confirmed CSF leaks may also demonstrate completely normal opening pressures. This is hypothesized to be due to increased permeability of dilated meningeal blood vessels and a decrease of CSF flow in the lumbar subarachnoid space. However, the presentation of patients with confirmed diagnosis may be very different from that of the clinical diagnostic criteria and cannot be considered authoritative. The volume of autologous blood and number of patch attempts for patients is highly variable. The areas of dura leak can be tied together in a process called ligation and then a metal clip can be placed in order to hold the ligation closed. The primary and most serious complication of SCSFLS is spontaneous intracranial hypotension, where pressure in the brain is severely decreased. This loss results in hindbrain herniation and causes major compression of the upper cervical spinal cord. The quadriplegia dissipates once the patient lies supine. The symptoms included orthostatic headaches and other features that are now recognized as spontaneous intracranial hypotension. A few decades earlier, the same syndrome had been described in French literature as . In 1. 94. 0, Henry Woltman of the Mayo Clinic wrote about . The full clinical manifestations of intracranial hypotension and CSF leaks were described in several publications reported between the 1. A study of patients with SCSFLS demonstrated no mutations in this gene. Abnormal findings of fibrillin- 1 has been documented in these CSF- leak patients, but only one patient demonstrated a fibrillin- 1 defect consistent with Marfan syndrome.
