Two days after the procedure, the patient's headache was completely resolved, and he continued to do well ever since and had returned to work as of June 4, 2001. Over the next few days, the patient noticed a positional component to the headache. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. The CSF Leak Association is a Scottish Charitable Incorporated Organisation (Charity No. You may need surgery if other treatments are not successful or you have a complex type of leak. You should consult a physician or other healthcare provider in all matters relating to your health, and particularly in respect to any symptoms that may require diagnosis or medical attention.

The CSF pressure prior to injection of the tracer was noted as “low” with scant CSF return. Where the leak site is not known, a high volume blood patch (typically 20ml) is injected into the lumbar spine (less commonly, the thoracic spine). Szeinfeld M Ihmeidan IH Moser MM Machado R Klose KJ Serafini AN.

MRI of the thoracic spine revealed mild T8-T9 disc bulging but no contrast enhancement of the meninges. The meningeal enhancement and subdural fluid collection result from venous hypervolemia consequent to CSF hypovolemia [21,22]. Our comprehensive evaluation often identifies CSF leaks in people whose symptoms have not responded to conventional treatment. The Canadian journal of neurological sciences. This includes bed rest, hydration, an abdominal binder, and caffeine.

SC046319) promoting awareness of cerebrospinal fluid (CSF) leaks, with a particular focus on spinal CSF leaks. For these procedures, the physician uses CT guidance to inject a small amount of the patient’s own blood or a plug of fibrin (the fibrous protein in blood that helps it clot) into the spinal canal. On MRI, there was diffuse enhancement of the thickened dura, findings compatible with CSF leak (Figure 3). CT scan: This noninvasive diagnostic imaging procedure uses a combination of X-rays and computer technology to produce detailed imaging of bones and different planes of the brain. CSF leakage through the ears or nose should be diagnosed and treated quickly and effectively to prevent. Caffeine, (which may help stimulate CSF production and has pain-relieving effects) Her second blood patch was performed in October 2002 under fluoroscopy at C7-T1 using 20 cc of autologous blood. Kroin JS Nagalla SK Buvanendran A McCarthy RJ Tuman KJ Ivankovich AD. All information on this site is provided as an information resource only, and is not to be used or relied on for any diagnostic or treatment purposes. An 111Indium radioisotope cisternogram was performed and did not show any extravasation of activity from the thecal sac to suggest CSF leak.

We report on the management of four consecutive cases that were referred to our pain management department over an 18-month period and review of the literature on the topic. If reasonable attempts at targeted epidural procedures fail to control the symptoms, then surgical interventions may become necessary. This is known as a spontaneous CSF leak. Treatment can be either medical or surgical. While CSF leaks are often misdiagnosed, Duke neuroradiologists are among the few experts in the country skilled at finding and repairing CSF leaks. For the therapeutic response to be long lasting, sealing of the dural tear with a clot is required [26,27]. In some cases, it is not immediately clear what the cause of the CSF leak is. Treatment for a CSF leak depends on the type and location of any hole or tear, as well as the underlying cause. Previous abortive medication attempted included NSAIDS, mild opioids, and inhaled triamcinolone, all without relief. Benzon HT Nemickas R Molloy RE Ahmad S Melen O Cohen B. Sugino T Matsusaka Y Mitsuhashi Y Murata K Sakaguchi M. Ozaki Y Sumi Y Kyogoku S Shindoh N Katayama H. Spelle L Boulin A Pierot L Graveleau P Tainturier C. Schievink WI Meyer FB Atkinson JL Mokri B. Messori A Simonetti BF Regnicolo L Di Bella P Logullo F Salvolini U. Bruera OC Bonamico L Giglio JA Sinay V Leston JA Figuerola ML. A “directed” epidural blood patch, placed in close proximity to the level of suspected CSF leak, is effective in most patients. However, increasing cases of spontaneous intracranial hypotension are being recognized as a result of higher awareness and improved detection practices.

After the procedure, the patient experienced 50% pain, but a low-grade headache at the top of her head and neck persisted. Most patients who have a spinal CSF leak may require more than one EBP, in fact they may require several to fix their leak(s). Learn more from Cleveland Clinic about causes, symptoms, treatment, recovery and more. Where the leak site is known, blood will be injected as close to it as possible. In particular, there was no evidence of leptomeningeal enhancement. Given the positional nature of the headaches, the patient was referred for an epidural blood patch at C5-C6 in July 2002. See AFTER CARE. SPINAL CSF LEAK CANADA, 45 O'Connor Street, suite 2000, Ottawa, ON, K1P 5E1, Canada. See AFTER CARE. The fluid is contained by the meninges, a series of protective membranes that surround the brain and spinal cord. Treatments for spinal CSF leaking vary from conservative to surgical procedures. The most common cause of postural headache is dural puncture following spinal tap or surgery. When conservative management fails, the pain management clinician is called upon to administer an epidural blood patch. The specific situation will dictate the course of action. A 36-year-old salesman developed a headache spontaneously one morning in September 2001 and, as the day progressed, his pain was worsening, with bifrontal and bioccipital nuchal distribution. Headache. Surgical repairs can include suturing, the application of artificial dura patches and the use of aneurism clips.

This constitutes the basis for the recommendation that the blood patch be performed at one to two spinal segments below the level of dural tear in cases of post dural puncture headache [26].

The leaking CSF may favor clot formation at the site of dural tear. Some common treatments for a CSF leak include: Conservative. Invasive measures are considered when conservative management fails, and these comprise epidural blood patch as well as surgical repair [4,6]. The loss of CSF causes the previously cushioned brain to sag inside the skull, which results in a headache. Following myelography, she had a postdural puncture headache, which manifested as exacerbation of the current headache. Furthermore, there was evidence of an eccentric disc extrusion and a free disc fragment at T4-T5 with moderate cord compression. CT myelography evidence of a curvilinear contrast enhancement (arrow) in the dorsal epidural space measuring 1 cm long and 1 mm thick at T6-T7, consistent with CSF leak. This type of patch is referred to as a “blind” or ”non-targeted” or “non-directed” epidural blood patch (EBP) because the procedure involves the injection of the patient’s own blood into the spinal epidural space without knowledge of the level of the site of the leak. For CSF leaks that are draining into the spinal canal, there are other treatments, such as blood patches or fibrin patches. The coagulability of the blood is essential as EDTA-containing blood, saline, dextran-40, and hetastarch did not result in persistent CSF pressure elevation in a rat model of dural puncture [27]. There was no immediate relief of the headache, but over the next 3–5 weeks, the patient noticed at least an 80% decrease in her headaches, which has continued to improve since.

A surgical repair may be performed where a patient fails to respond to a blood patch or a blood patch fails, if the site of the leak has been identified. Diagnostic findings include a low opening CSF pressure on spinal tap, CSF pleiocytosis, and increased protein concentration as well as characteristic findings on radiological studies and radioisotope cisternograms.
