Can we do lumbar puncture in increased intracranial pressure?
Although generally considered innocuous, there may be considerable danger when lumbar puncture is performed in the presence of increased intracranial pressure, especially when a mass lesion is present.
What are the complications of CSF leak?
Cranial CSF leaks Clear, watery drainage from the nose or ear (on one side) Hearing loss. A metallic taste in the mouth. Meningitis.
Can a spinal fluid leak cause death?
A cranial CSF leak results in a runny nose and carries a high risk of meningitis, an inflammation of the membrane around the brain and spinal cord, which can be fatal and requires emergency attention.
Why would we not do a lumbar puncture on a patient with ICP?
While some patients with CT evidence of increased ICP have undergone LP without herniation, CT findings of increased ICP place patients at a dramatically increased risk for herniation if an LP is performed. Therefore, LP should be avoided when any signs of increased ICP are seen on CT.
What is the risk of doing a lumbar puncture on a patient with intracranial hypertension?
Avoiding cerebral herniation – Cerebral herniation is a rare, but usually fatal, complication of an LP performed in an individual with increased intracranial pressure (ICP).
Can a CSF leak affect your heart?
Through echocardiographic evaluation and detailed medical history, we estimate that up to 20 % of patients presenting with a spontaneous CSF leak may have some type of cardiovascular abnormality.
How urgent is a CSF leak?
What can go wrong with a lumbar puncture?
A small amount of CSF can leak from the needle insertion site. This can cause headaches after the procedure. If the leak continues, your headache can be severe. You may have a slight risk of infection because the needle breaks the skin’s surface, providing a possible way for bacteria to enter the body.
Is lumbar puncture a high risk procedure?
Other complications – LP is a relatively safe procedure, but minor and major complications can occur, including headache and minor neurologic symptoms, such as radicular pain or numbness. (See ‘Complications’ above.)
When should you avoid a lumbar puncture?
Avoid lumbar puncture in patients in whom the disease process has progressed to the neurologic findings associated with impending cerebral herniation (ie, deteriorating level of consciousness and brainstem signs that include pupillary changes, posturing, irregular respirations, and very recent seizure)
What are the possible complications of lumbar puncture (LP)?
Intracranial hypotension syndrome as a complication of diagnostic lumbar puncture is a rarely observed entity. Intracranial hypotension syndrome is characterized by postural headache, neck pain/stiffness, blurred vision, nausea, vomiting, clouding of consciousness, dizziness and vertigo.
What causes intracranial hypotension after a puncture?
Intracranial hypotension occurs most commonly after lumbar puncture or after an idiopathic tear of the spinal dura. Evidence suggests that new “atraumatic” needles, as well as smaller-bore needles and few passes of the needle to perform the lumbar puncture, are associated with a lower incidence of postspinal headache.
What is the pathophysiology of intracranial hypotension?
Intracranial hypotension may occur from a tear in the dura caused by trauma, surgery, or lumbar puncture. The etiology of the headache is due to traction on the dura and vessels at the base of the brain. The headache associated with intracranial hypotension typically improves while the patient is recumbent and worsens upon sitting or standing.
Is intracranial hypotension more common in men or women?
However, it is more common in women than in men, and the peak age of diagnosis is 40. Intracranial hypotension often results from a cerebrospinal fluid leak. CSF leaks can occur without an identifiable cause, or they can be caused by:
