Dural Grafts in Trauma Craniotomy and Decompressive Craniectomy

In trauma craniotomy and decompressive craniectomy, the dural graft is often used to perform an expansile duraplasty, closing the dura loosely over a swollen brain. These cases happen at any hour, with surgeons who need a ready-to-use graft in the right size immediately. For trauma centers, availability and simplicity matter as much as the graft's characteristics.

Trauma neurosurgery is unlike elective tumor or spine work, and trauma centers often carry the heaviest emergency neurosurgical load in their region.

Cases arrive unannounced, often at night, and the team on duty may include surgeons, residents and OR staff who do not handle dural grafts every day. For a distributor, trauma centers are demanding accounts that reward reliability above all. This article explains how dural grafts are used in trauma, what trauma teams need from a product and how a distributor can support them. For broader clinical background, see our article on dural grafts in neurotrauma.

How are dural grafts used in trauma surgery?

Trauma creates several situations in which a dural graft may be needed:

• Decompressive craniectomy, where a large bone flap is removed to relieve raised intracranial pressure and the dura is opened widely.
• Craniotomy for evacuation of a hematoma, where the dura may be torn, contused or deliberately opened.
• Open or depressed skull fractures with dural lacerations.
• Penetrating injuries with dural defects.

In each case, the surgeon decides whether the dura can be closed primarily, needs a graft, or should be left partly open with a protective layer. The urgency of the operation and the condition of the brain often shape that decision.

Contamination is another trauma-specific factor. Open fractures and penetrating injuries may bring debris into the wound, and the surgeon will debride the area before any repair. Whether and how to place a graft in a contaminated field is a clinical judgment that the rep should never comment on; the IFU and the surgeon's experience guide it.

What is an expansile duraplasty?

In decompressive craniectomy, the aim is to give the swollen brain room to expand outward. Opening the dura widely is part of that aim. Many surgeons then cover the exposed brain with a dural graft placed loosely, so that the dura is enlarged rather than closed tightly. This is often called an expansile or augmentative duraplasty.

Decompressive craniectomy itself has been studied in major randomized trials, including DECRA, published in 2011, and RESCUEicp, published in 2016, both in the New England Journal of Medicine. These trials concern the operation, not any particular graft, and should not be cited as evidence about graft products.

Do trauma surgeons suture or onlay the graft?

Both approaches are used. Some surgeons suture a graft to the dural edges to create a secure, enlarged envelope. Others lay an onlay graft over the opening, sometimes without fixation, because it is faster and avoids tension on swollen tissue. Some surgeons also consider how the dural layer will affect dissection when the bone flap is replaced at a later cranioplasty.

DESU's membranes cover both approaches. DURASHEET is a suturable dural graft matrix of pure Type I bovine collagen, usable on both surfaces. DECOLL is a collagen dura membrane of the same material intended for onlay use. Both come in four sizes, and the larger sizes are relevant for the wide openings of decompressive surgery. Exact dimensions are in the catalog and IFU.

What does a trauma team need from a graft?

Trauma teams judge a product by how it performs under pressure, with a team that may not use it often.

None of these needs requires a claim about outcomes. They are practical requirements that any trauma OR manager will recognize.

The staff mix matters too. In many trauma centers, the neurosurgical resident or the on-call attending may be supported at night by OR staff who usually work in general surgery or orthopedics. They may never have opened a dural graft. A product that is self-explanatory on the shelf and in the package reduces the chance of delay or error in that situation.

What other products are involved in trauma cases?

Patients with severe traumatic brain injury often need intracranial pressure monitoring and, in many cases, external ventricular drainage. DESU manufactures the EVD-010 Series external ventricular drainage system, with a 31 cm ventricular catheter, a 30 cm measuring scale, a 150 ml drip chamber and an 800 ml drainage bag, available with a standard or antibiotic-impregnated catheter.

Whether to place a drain, and which system to use, is a clinical decision. The EVD-010 Series is mentioned here only because trauma services often use both product types, not as a recommendation for any patient. For a distributor, the point is that the same trauma team may use both a dural graft and an external drainage system, and a single manufacturer relationship can support both. EVD management is covered in detail in the consensus statement on external ventricular drains published in Neurocritical Care in 2016.

How should a distributor support a trauma center?

Trauma centers value suppliers who think about the night shift. Practical steps:

Stock where the cases happen

Make sure grafts, especially the larger sizes, are stocked in the room or core used for emergency neurosurgery, not only in the elective neuro rooms.

Train the people on call

Run short in-services for night and weekend OR staff, not only the day team. Cover the difference between the sutured and onlay products, the sizes and the implant recording.

Keep it simple

Avoid overloading the trauma shelf. Two clearly labeled products in the sizes trauma surgeons actually use are easier to manage at three in the morning than a crowded shelf. If the elective neuro rooms stock more sizes, that is fine; the trauma shelf should hold what trauma cases need.

Be reachable

Give the trauma team a clear contact for urgent stock questions, and agree how emergency replenishment works.

Plan for clusters of cases

Trauma volumes are uneven. A busy weekend can use several large grafts in a short time. Agree with the hospital how quickly used units are replaced and keep a buffer of the larger sizes, either on consignment or in the distributor's nearby stock. Review usage regularly with the OR manager so the buffer reflects real demand.

What should not be said about trauma use?

Do not claim that a graft improves outcomes after traumatic brain injury, reduces infection or lowers the risk of complications at cranioplasty. These claims would need specific clinical evidence. Talk about the product, its availability and its handling, and let the surgeons draw their own conclusions from their experience.

Talk to a DESU product specialist

If you support trauma centers or neurosurgery services that perform decompressive surgery, DESU's product specialists can help you plan graft availability, provide documentation for DURASHEET, DECOLL and the EVD-010 Series and discuss what your market requires.
