What is the purpose of this trial?

This trial examines two treatments, CraniSeal and DuraSeal, to determine which better prevents cerebrospinal fluid (CSF) leaks after brain surgery. Researchers aim to ensure CraniSeal performs as well as DuraSeal and to identify any side effects or infections. The trial includes individuals scheduled for planned brain surgery involving cutting the dura (the brain's protective covering) and excludes those with certain health issues, such as severe kidney problems or uncontrolled diabetes. As a Phase 4 trial, the treatment has already received FDA approval and proven effective, and this research seeks to understand its benefits for a broader range of patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What is the safety track record for these treatments?

Research shows that both CraniSeal and DuraSeal have received approval for use, indicating they have undergone safety testing in humans. Studies have found that DuraSeal carries a 4.5% risk of causing cerebrospinal fluid (CSF) leaks after surgery. Although this poses a safety concern, the risk remains relatively low.

For CraniSeal, detailed safety data from past studies isn't available in the sources provided. However, the Phase 4 status of this trial suggests that CraniSeal is likely safe for most people. Phase 4 trials typically occur after a treatment's approval, so earlier research should have identified any major safety issues.

In summary, both CraniSeal and DuraSeal have been used in practice and are generally considered safe, though some risks exist with any medical treatment. This trial aims to compare the two to ensure CraniSeal is as safe and effective as DuraSeal. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about CraniSeal because it offers a new way to manage cerebrospinal fluid leaks, potentially improving outcomes compared to existing treatments like DuraSeal. Unlike other sealants, CraniSeal may provide a more robust and lasting seal due to its unique composition, which could reduce the risk of leaks and complications after surgery. This innovation could simplify post-surgical recovery and enhance patient comfort and safety.

What evidence suggests that this trial's treatments could be effective for preventing cerebrospinal fluid leaks?

This trial will compare CraniSeal and DuraSeal in preventing cerebrospinal fluid (CSF) leaks after brain surgery. Research has shown that CraniSeal is effective, with CSF leaks occurring in 8.2% of cases, similar to other sealants. Meanwhile, DuraSeal demonstrated a complication rate of 5.8%, comparable to CraniSeal. Both treatments generally minimize CSF leaks after surgery. Participants in this trial will receive either CraniSeal or DuraSeal to further evaluate their effectiveness. ^{1 2 3 6 7}

Published Research Related to This Trial

In a retrospective review of five cases of cerebrospinal fluid (CSF) leaks repaired with the DuraSeal Sealant System, four repairs were successful, indicating its efficacy in enhancing graft strength and forming a watertight seal during endoscopic skull-base surgery.

There were no complications associated with the use of DuraSeal, and its failure rate was comparable to that of Tisseel Fibrin Sealant, suggesting that DuraSeal is a safe and effective option for CSF leak repairs.

Cerebrospinal fluid (CSF) leaks are a common issue after spinal and cranial surgeries, particularly in patients with spinal tumors, highlighting the need for effective closure techniques.

The case reported demonstrates a complication where the DuraSeal® Dural Sealant, used to repair a CSF leak, caused thecal sac compression, indicating that while such sealants are helpful, they can also lead to significant complications if not monitored closely.

DuraSeal® is a synthetic product used to help prevent cerebrospinal fluid (CSF) leakage after cranial and spinal surgeries, which can lead to complications like delayed healing and infections.

However, there is a risk associated with its use, as demonstrated by a case where a patient experienced cord compression due to the expansion of DuraSeal® following cervical spine surgery, highlighting the need for careful consideration in its application.

The PEG hydrogel dural sealant demonstrated a safety profile comparable to standard dural sealing techniques, with similar rates of neurosurgical complications, surgical site infections, and cerebrospinal fluid leaks in a study of 237 patients.

This sealant was also significantly faster to prepare and apply, with 96.6% of cases taking less than 5 minutes for preparation and 85.7% taking under 1 minute for application, making it a more efficient option for surgeons.

DuraSeal, a dural sealant used to repair tiny durotomies during surgery, can expand significantly and potentially cause complications, such as nerve root compression, if not used cautiously.

In a case involving a 77-year-old woman, the use of DuraSeal after an intraoperative durotomy led to serious postoperative neurological issues, highlighting the need for careful monitoring of patients for signs of cauda equina syndrome following its application.

Current dural sealants are intended to prevent cerebrospinal fluid (CSF) leakage after intradural surgery, but systematic reviews indicate that no significantly effective sealant is currently available.

Future developments in dural sealants may focus on creating products that not only prevent CSF leakage but also possess antimicrobial and analgesic properties, enhancing patient safety and recovery.

Adherus dural sealant demonstrated a strong safety profile in endoscopic skull base surgery, with no reported postoperative cerebrospinal fluid leaks or other serious complications in a study of 26 patients, similar to a control group using DuraSeal.

Adherus was more easily identifiable on immediate postoperative MRI compared to DuraSeal (50% vs. 20.8%), while both sealants showed comparable quality of life outcomes as measured by SNOT-22 scores, suggesting Adherus is a viable alternative.
