Decompressive craniectomy
- 1. Care of thepatient with Craniectomy Evaluator: Mr L Anand [Asso professor, CON AIIMS BBSR] Presenter: Shruti Shirke M.Sc Neuroscience Nursing
- 3. CRANIOTOMY Defines a procedurewhere the cranial cavity is accessed through removal of bone to perform a variety of brain surgeries. Once the surgery is completed, the bone flap is returned to its previous position.
- 4. CRANIECTOMY Differs from craniotomyin that the bone is not replaced to its previous position; instead it is stored for future insertion or may be discarded (depending on pathology – e.g. infection). This results in a cranial defect. – If the bone flap needs to be discarded, it is replaced with a custommade implant.
- 5. CRANIECTOMY Is a neurosurgicalprocedure that involves removing a portion of the skull, where the patient's scalp is closed without re- implantation of the bone.
- 6. ROLE OF ACRANIECTOMY Increases buffering capacity of cranium. Allows outward herniation of brain tissue: preventing compression of brainstem structures. – reestablish brain perfusion. Intracranial pressure (ICP) reduction 15-85% depending on size of bone removed.
- 7. INDICATION Craniectomy may beused in nonemergent circumstances to augment the opening of a craniotomy. Decompressive Craniectomy is used in urgent or emergent conditions where there is substantial brain swelling from bleeding, stroke or infection.
- 8. CRITERIA FOR STROKE(MCA) Inclusion <96hfrom symptoms onset (recommended <48hrs) Infarct >1/2 MCA territory on imaging Premorbid MRS<_ 2 NIHSS 1a>1 Exclusion Pupil fixed or dilated Serious comorbid illness GCS <6 Life expectancy <3 years Uncorrected coagulopathy
- 9. PROCEDURE The neurosurgeon makesan incision in the scalp, and once the skin and underlying tissues have been cut and moved out of the way, a drill is used to make holes in the skull. The holes are connected with a saw, and a portion of the skull bone is removed.
- 10. PROCEDURE CONT.. Once thebone is removed, and any underlying clot that is compressing the brain is evacuated, or any bleeding around the brain has been controlled, relieving pressure in the brain, the skin and connective tissue overlying the brain are closed with sutures.
- 11. Positioning C-head fixator Markingon scalp Incision of scalp and retraction of scalp (keeping layer of connective tissue) Drilling and cutting skull of area of interest Cleaning and storing skull Separating dura mater
- 14. BONE FLAP STORAGEAFTER CRANIECTOMY After a decompressive craniectomy for brain swelling, bone flaps need to be stored in a sterile fashion until cranioplasty. Temporary placement in a subcutaneous pocket (SP) and cryopreservation (CP) are the two commonly used methods for preserving bone flaps
- 15. STORAGE OF BONEFLAPS Bone flap freezer Bone flaps can be kept there for months – years
- 17. BONE FLAP APPEARANCE(SITE) As the swelling begins to decrease, the patient’s head may be depressed until the skull is re-inserted. If the bone is being stored in the patient’s abdomen, it will feel like a hardened area in the abdomen when palpating.
- 18. BONE FLAP REPLACEMENT Oncethe patient’s brain swelling has subsided and his or her condition is stable, the bone or other form fitting artificial material is implanted in a procedure called a cranioplasty. This procedure can occur weeks to even years after the bone flap removal.
- 19. CRANIOPLASTY Cranioplasty is asurgical procedure to correct a deformity or defect of the skull. Reconstruction of the skull-cranioplasty may be performed with titanium mesh or other artificial products. Cranioplasty - Re-implantation of the bone flap. Typically, rigid fixation is achieved with small compatible titanium fasteners (plates) that do not activate metal detectors in airports.

- 21. COMPLICATIONS THE MAJOR RISKSOF CRANIECTOMY INCLUDE THE FOLLOWING: Bleeding Infection Seizures Abnormalities in cerebrospinal fluid (CSF) absorption Further damage to the brain Stroke Death
- 22. COMPLICATIONS CONT.. Post Cerebralcontusion expansion: usually occurs within first two days.
- 23. Coagulopathy. Preoperative noncontrast CTscans of an SDH in a patient on a regimen of warfarin (A and B). Despite reversal of the coagulopathy before surgery, marked hemorrhagic blossoming occurred as evidenced by postoperative noncontrast images (C and D). Note in panel C the development of an extraaxial SDH contralateral to the decompressed hemisphere.
- 24. COMPLICATIONS CONT.. Bleeding complicationsinclude: • newly developed subdural or epidural hematomas potentially within the first few hours (for epidurals) or a few days postoperative.
- 25. A and B:preoperative noncontrast CT scans obtained in a patient with traumatic subarachnoid hemorrhage and a small SDH who underwent decompressive craniectomy. C and D: postoperative noncontrast CT scans showing evolution of an occipital EDH (arrow),
- 26. COMPLICATIONS CONT.. Post traumatichydrocephalus can occur one month post-operative.
- 27. COMPLICATIONS CONT.. Subdural hygromadue to alteration in the dynamics of CSF circulation.
- 28. SYNDROME OF TREPHINE Sinkingskin flap syndrome. Caused by changes in the pressure gradient of intracranial pressure and atmospheric pressure. Patients with this syndrome benefit having the bone flap replaced sooner rather than later.
- 29. SURGICAL SITE INFECTION(SSI) SSI is a serious complication of cranioplasty. Dehiscence: Defined as a diastase of facing flap borders occurring along the line of suture, with different degrees of exposure of underlying tissues.
- 30. Ulcer: Defined asa loss of substance occurring inside the skin flap, usually distant from the line of suture, constantly presenting with underlying tissues exposure. SSI CONT..
- 31. SSI CONT.. Necrosis: Definedas a large, discolored area of complete loss of skin viability, both on flap contour and on the surrounding skin border.

- 34. WOUND CARE •Inspect theincision on the head and abdomen (if present) to ensure edges remain well approximated, and staples/sutures are intact. •Monitor for redness around the incision, discharge, and any other signs of infection. •Incision is usually left open to the air, dependent on the physician’s order and preference.
- 35. WOUND CARE CONT.. •Suturesare usually removed in 2 weeks; however, practice differs between physicians. •Topical agents on the incision may or may not be prohibited by the physician. – Ointments commonly used are topical antibiotic ointments •Incision should be covered if patient is going outside to prevent sunburn.
- 36. HAIR CARE oPatients whohave had a bone flap removed may still have their hair washed. oDo not submerge the incision until all staple sutures have been removed or as per direction of your physician. oBe gentle when handling this area and do not rub too vigorously. oUse a mild shampoo with no strong perfumes. oDo not direct shower head directly to site.
- 37. SAFETY CONSIDERATIONS •When used,a helmet should be fit to the patient by an orthotics specialist to minimize pressure on the open cerebrum as well as skin over the skull. •Helmets should be removed when patient is in bed and when bathing. •Each facility and physician have different protocols and varying use of helmets.
- 39. SAFETY CONSIDERATIONS CONT.. Positioningmay be supported with towels, pillows, and positioning devices to prevent pressure onto the cerebrum and attempt to stay off the site. Signage above the patients bed allows all health care providers to recognize that patient has no bone flap.
- 40. Post-op craniectomy patientsare at an increased risk for falls. Some falls prevention strategies to consider: Keep bed at lowest level. Ensure room is not cluttered. Ensure patient is supervised at all times during mobilization (may use a helmet during this time if part of patient’s care). General supervision as much as possible. SAFETY CONSIDERATIONS CONT..
- 41. SOME FALLS PREVENTIONSTRATEGIES CONT.. Ensure patient uses non-slip shoes when necessary. May want to have patient’s room near nursing station so staff can better monitor. Purposeful rounding (e.g. assess patient’s need to use bathroom prior to bedtime). May consider using bed rail pads on the patient’s bed in case patient hits head on bed rails (e.g. while asleep, during seizure).
- 42. Always remember….. Conduct regularneurological assessments on patients post-craniectomy

- 45. CONCLUSION Successful craniectomy iswhen patient is hemodynamically stable while surgery, standard level of sterility is maintained, no SSI, and prevention of other complications and adequate management of these complications. Critical observation by the nurses. Dedicated team work is essential for better outcome of patient.

- 48. Keep the incisionclean. Craniotomy incisions are usually closed with sutures or surgical staples. Follow the physician’s instructions regarding incision care. Some physicians want patients to keep the incision dry, while others allow patients to gently wash their hair (and the incision) soon after surgery. Do not apply any lotions, creams or ointments to the incision, unless instructed to do so by your healthcare provider. Cover the incision with a bandana or loose hat when going outside.
- 49. Watch the incisionfor signs of infection or complications. An incision that becomes red and warm to the touch may be infected. Leaking or oozing fluid (after the bandage has been removed) can indicate a possible complication, such as increased brain pressure or a cerebrospinal fluid leak. Any abnormalities should be reported immediately.
- 50. Control Pain. Mostpatients go home with a prescription for a small number of narcotic pain pills. If the pain pills are not adequate to control pain, or if the patient is still having severe pain when the narcotics have run out, notify the healthcare provider. Uncontrollable or persistent pain can be a sign of complications.
- 51. Gradually return toactivity. Friends and family members may want to pamper the person who’s had surgery, but it’s best to allow someone to do as much as possible independently. “Simple everyday activities such as getting dressed, grooming and meal prep are fantastic exercise and probably just as important as formal physical and occupational therapy,” says Michael O’Dell, chief of clinical services in the Department of Rehabilitation Medicine and medical director of the Inpatient Rehabilitation Medicine Center at New York-Presbyterian Hospital-Weill Cornell Medical Center in New York.
