Primary Outcome Measures:
  • Percent(%) Success in Obtaining a Watertight Closure Following Assigned Treatment (Spinal Sealant or Control) [ Time Frame: Intra-operative ] [ Designated as safety issue: No ]

    Percent(%) success in obtaining a watertight closure following assigned treatment (Spinal Sealant or Control) where success is defined as:

    A watertight closure of the dural repair intraoperatively after study treatment, confirmed by Valsalva maneuver at 20-25 cm H2O for 5-10 seconds.

Other Outcome Measures:
  • Incidence of Post-Operative CSF Leaks [ Time Frame: 90 Days ] [ Designated as safety issue: Yes ]

    Percentage of participants with CSF leaks within 90 days post-operatively as determined from clinical diagnosis by one of the following methods:

    • CSF leak or pseudomeningocele related surgical intervention (i.e., breaking skin) within 90 days post-procedure; or
    • CSF leak confirmation by diagnostic testing within 90 days post-procedure; or
    • CSF leak confirmation by clinical evaluation within 90 days post-procedure

  • Incidence of Post-Operative Surgical Site Infections (SSIs) [ Time Frame: 90 Days ] [ Designated as safety issue: Yes ]

    •Percentage of participants who incur an SSI within 90 days post-procedure determined by clinical diagnosis

    SSIs were diagnosed and classified in accordance with the Centers for Disease Control (CDC) criteria for evaluation and diagnosis of nosocomial surgical site infections and were classified as one of the following (Superficial, Deep or Organ/Space).

Detailed Description:

Neurosurgical procedures in the spine often involve incision of the dura mater to access the spinal cord. If the dural incision is not properly repaired and watertight closure is not achieved cerebrospinal fluid (CSF) can escape presenting a risk for significant morbidity. The most frequent complication of CSF leak is recurring headache complicated with symptoms of nausea and vomiting. Furthermore fluid collection under skin prevents proper wound healing and may lead to wound breakdown and infection of the incision or both. Persistent CSF leak has also been associated with the development of cerebellar hemorrhage and subdural hematoma. Primary repair and watertight closure are paramount to minimizing risk and sequelae associated with CSF leak.
