The high-speed drill attachment is converted to a cutting bit w ith a footplate and used to connect each pair of bur holes circumferentially. Center holes may be m ade later in the bone ap for epidural tack-up sutures.

Venous epidural hem atom as sometim es require application of gel foam soaked in throm bin and gentle pressure. The hem atom a is often adherent to the bleeding vessel. This may be removed using irrigation and suction. The dural edges may then be grasped w ith ne -toothed forceps. If the brain is signi cantly edem atous and the dura is taut. Dural vessels m ay be coagulated with the bipolar at the edges of the cut dura. The dural ap or aps should be weighted with hem ostats in order to prevent shrinkage during the procedure as m uch as possible.

The dural edges should be secured with braided nylon sutures. Well-form ed hematom as m ay be grasped with biopsy forceps and gently elevated from the brain surface while ushing the area with ample irrigation. The site should be irrigated again to ensure no active bleeding prior to dural closure. A brain retractor blade m ay be used to gently depress the brain during this phase.

If an active bleeding source is identi ed which is not always possible. Gentle irrigation with sterile saline should be used and the entire perim eter of the dural exposure explored with adequate lighting to ensure that the hem atom a has been completely evacuated.

The source is often a cortical surface vein or artery. A central epidural tacking stitch may be brought out through tw o holes drilled in the bone ap. Over the Epidural tack-up sutures are placed through small drill holes placed around the perimeter of the craniotomy.

The dura may be closed with simple running. Prior to placing the nal few sutures. For large dural defects not am enable to prim ary closure due to shrunken dura.

The planned bur hole incision sites should fall along the superior lim b of the question m ark. A shoulder roll is placed longitudinally beneath the ipsilateral shoulder.

This will facilitate a m ore extensive opening. The anterior incision is positioned just anterior to coronal suture and the posterior incision. The incision can be further tailored to the location and size of the hematoma. If the CT appearance of the extra-axial uid is both hypodense and homogeneous. Trace out a reverse question m ark—t ype incision over the a ected hem isphere. Use the craniotome to create a small bone ap. The pericranium is opened w ith Bovie electrocautery and sw ept to either side w ith a periosteal elevator.

The bone is elevated—using a blunt surgical tool to dissect any remaining dural attachments to the undersurface of the bone—and set aside in antibiotic solution.

The bone ap will be 4 to 5 cm in diam eter. Self-retaining retractors are placed. Apply bone w ax to the bony edges as necessary.

Pearls Bur Holes Right Place a single bur hole at each incision site. The temporalis is incised and is re ected w ith the skin incision. For the craniotomy. A footplate attachment. The membrane should be coagulated w ith bipolar electrocautery and opened sharply w ith a no. The subdural m em brane often has a brown-green hue. Place epidural tacking stitches circumferentially w ith braided nylon sutures. Line the edges of the craniotomy site w ith thin strips of gelatin sponge soaked in thrombin.

If not. Coagulate the dural lea ets w ith bipolar electrocautery to prevent bleeding into the subdural space and to ensure opening of the dura across the full surface area of the bur hole. A silk suture. Placing gelatin sponge soaked in thrombin in small pieces or strips along the undersurface of the bone can be helpful in stopping bleeding from membranes in di cult-to-reach areas. Membranes and septations can be broken apart w ith bipolar coagulation.

Elevate the syringe. If the uid introduced through one hole does not exit the second hole. The red rubber catheter m ay be guided in any direction where there is presum ed to be hem atom a. The inner m em brane. It is possible for the catheter to penetrate brain parenchym a or to tear a bridging vein. Monitor the bur hole sites during this process to ensure that there is communication w ithin the subdural space betw een the tw o holes. Halt irrigation and reassess. If acute hem orrhage is suspected and the uid does not clear with continued irrigation.

Craniotomy also facilitates ushing out of m ore organized rests of hem atom a not accessible via bur holes. The vascularized m embrane can bleed. Consider taking a specimen of membrane as w ell. It is important to control active bleeding. Cover each dural opening w ith a piece of gelatin sponge to prevent further air or blood from entering the subdural space. The drain can be advanced further if no resistance is encountered. The cavity is irrigated to remove most of the air. In such circum stances.

A subgaleal drain m ay be left in place as needed to help prevent a postoperative subgaleal hem atom a or leakage of subgaleal blood into the subdural space.

The dura is closed in an interrupted or running fashion. Gelatin sponge is placed over the cavity prior to replacing the bone ap to prevent air and blood from getting into the subdural space during closure.

A sterile dressing is applied. Th e skin aroun d th e in cision s is clean ed of all blood products an d su rgical d ebris. It is som et im es n ecessar y to create a groove w ith a m atch st ick bu r on th e u n dersu rface of th e bon e ap —at th e bur h ole site—in order to avoid kin king of th e drain at it s exit site. A sim ilar sut ure is placed aroun d th e subgaleal drain.

Th e skin is closed w ith staples or w ith nylon su t ures in a ver t ical m at t ress fash ion. Th e in cision site is irrigated w ith an t im icrobial solut ion. For th e sm all cran iotom y: A braided sut ure is placed in a pursest ring fash ion aroun d th e su bdural drain exit site to an ch or th e drain to th e skin an d seal th e sp ace arou n d th e drain.

The ideal entry point is usually sim ilar to a ventriculostomy entry point. Make a small stab incision at the desired insertion site w ith a no. The entry point for the catheter insertion is chosen over a relatively thick part of the SDH that is safely accessible. The tw ist drill can be started in the usual perpendicular angle. Usually this means tilting the drill tip posteriorly in order to angle the hole posteriorly. Since the catheter is usually in place for only 12 to 48 hours.

A com plex extern al ven t ricular drain system is n ot required sin ce ICP w ill n ot be m easured. Th e skin is prepared in a sterile fash ion. Th e drain is placed to gravit y drain age.

The head is stabilized w ith May eld three -point xation. The head of bed is elevated slightly. Carry the incision dow n to the pericranium above the superior temporal line and dow n to the temporalis fascia in the temporal region. Carry the incision across midline. The super cial temporal fascia and temporalis muscle are opened.

Pericranium and muscle are advanced w ith a combination of periosteal elevator and monopolar electrocautery. A few rolled sponges are placed beneath the ap as it is re ected and secured. Rem ain above the zygom a when approaching the inferior aspect of the incision. Leave the frontalis muscle intact if possible.

The ap is secured w ith mini-tow el clips. Pen eld no. The dura is stripped from the undersurface of the bone. An additional pair of holes are placed straddling the midline..

The base of each hole is cleared w ith a curette. The craniotome is used to connect each pair of bur holes circumferentially, taking care to stay low in the frontal and temporal regions and making the nal cut in the region of the superior sagittal sinus. The bone ap is carefully elevated aw ay from the underlying dura and set aside in antibiotic solution.

Bone w ax is applied to the bony edges w here necessary.
