Effectiveness and Safety of TachoSil® Fibrin Sealant Patch for Supporting Dural Sealing Among Adult Inpatients
What this study is about
This reviewing past data observational group of participants study compares the effectiveness and safety of adjunctive TachoSil® fibrin sealant patch with DuraSeal® hydrogel sealant for supporting dural sealing in adult patients undergoing cranial or spinal surgery at participating United States hospitals.
View original scientific description
This retrospective observational cohort study compares the effectiveness and safety of adjunctive TachoSil® fibrin sealant patch with DuraSeal® hydrogel sealant for supporting dural sealing in adult patients undergoing cranial or spinal surgery at participating United States hospitals. Medical records will be reviewed to assess clinically evident cerebrospinal fluid leak or clinically evident pseudomeningocele within 90 days after surgery. The study will use 1:1 propensity score matching to evaluate whether TachoSil® is non-inferior to DuraSeal® and will assess additional effectiveness and safety outcomes.
Interventions
DRUG
TachoSil®
TachoSil® is an absorbable fibrin sealant patch consisting of equine collagen coated with human fibrinogen and thrombin.
DEVICE
DuraSeal®
DuraSeal® sealants are polyethylene glycol (PEG) based hydrogel.
Primary outcome measures
Risk of Clinically Evident CSF Leak or Clinically Evident Pseudomeningocele
Time frame: Within 90 days post surgery
A clinically evident CSF leak is defined as clear fluid leaking through the surgical incision or orifice verified by a glucose concentration test or β-2 transferrin test. A clinically evident pseudomeningocele is defined as a subcutaneous visible and/or palpable fluid accumulation adjacent to or at the site of surgical incision suspected to be CSF. If there is not a collection of CSF/pseudomeningocele, or active leak that can be sampled for β-2 transferrin test, but the participant had symptoms consistent with intracranial hypotension and/or an ex vacuo type subdural hematoma, the participant will be considered as having clinically evident CSF leak or pseudomeningocele.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Aged ≥ 18 years
- Had an inpatient encounter to select sites with a cranial or spinal neurological surgery that involves dural sealing performed and discharged during January 1, 2017, and March 31, 2026
- Had use of TachoSil® or DuraSeal® sealants during the cranial or spinal neurological surgery as supportive dural sealing method Note: Any surgery meeting the above criteria is considered index surgery
Exclusion criteria
- Index surgery was trauma-related
- Had an infection within 7 days prior to index date
- Had any neurosurgery involving dural opening during the 12-month look-back period
- Had neoplasm of dura mater/meningioma, requiring resection of dura during index visit (the earliest visit meeting selection criteria) or 12-month look-back period
- Was pregnant at index visit
- Had a CSF leak during the 12-month look-back period
- If the surgical approach was transbasal or transpetrosal, if the arachnoid membrane and CSF- containing system remained intact, or if there was \>1 dura opening (excluding extra ventricular or lumbar drains) during index surgery
- Had use of Evarrest patch, Tisseel, Adherus, CraniSeal, Duragen, fibrin glue or other dural sealing products during index surgery
- Had radiation therapy to surgical field in the 3 months prior to index date
- Had chronic corticosteroid use in the 3 months prior to index date
- Had both TachoSil® and DuraSeal® used for dural closure during index neurological surgery

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
