Minimally Invasive Neuroendoscopic Surgery for Spontaneous Intracerebral Hemorrhage: A Review of the Rationale and Associated Complications.

Spontaneous intracerebral hemorrhage (ICH) is associated with a poor prognosis. Its mortality rate exceeds 40%, and 10-15% of survivors remain fully dependent. Considering the limited number of effective therapeutic options in such cases, the possibilities for surgical interventions aimed at removal of a hematoma should always be borne in mind. Although conventional surgery for deep-seated ICH has failed to show an improvement in outcomes, use of minimally invasive techniques-in particular, neuroendoscopic procedures-may be more effective and has demonstrated promising results. Although there are certain risks of morbidities (including rebleeding, epilepsy, meningitis, infection, pneumonia, and digestive tract disorders) and a nonnegligible risk of mortality, their incidence rates after neuroendoscopic evacuation of ICH compare favorably with those after conventional surgery. Prevention of complications requires careful postoperative surveillance of the patient and, preferably, treatment in a neurointensive care unit, as well as early detection and appropriate management of associated comorbidities.

Role of Hypertonic Sodium Lactate in Traumatic Brain Injury Management.

Traumatic brain injury (TBI) following increased intracranial pressure (ICP) is a neuroemergency case which should be managed promptly to prevent secondary brain injury. This will lead to a condition called cerebral energy dysfunction which is an important determinant factor toward worse outcome. Lactate, which was historically known as an end waste product, now is considered as an alternative cerebral energetic fuel. Hypertonic sodium lactate (HSL) is a promising hyperosmolar fluid which serves not only to decrease ICP but also to readily supply exogenous lactate to fulfill increased cerebral energy demand. Pioneer studies have shown the harmlessness and usefulness of HSL in treating pathological condition including TBI.

Duraplasty using amniotic membrane versus temporal muscle fascia: A clinical comparative study.

In the field of neurosurgery, often the dura mater cannot be sutured, and consequently, it requires a duraplasty procedure using a dural fascial graft. Since 1890, various materials have been researched as dura mater substitutes. Amniotic membrane, for example, is suitable as a dural graft material and has been used in neurosurgery since 2012. However, there has been little research on human patient's dural healing after the use of amniotic membrane in their duraplasty procedure. To address this gap, a clinical experimental study was undertaken to evaluate the human dural healing of 16 patients who had undergone duraplasty in decompressive craniectomy surgery at Dr. Soetomo General Hospital, Surabaya. The amniotic membrane allograft, was sutured to cover the dural defect for eight randomly chosen patients (Group I). The fascial autograft from the temporal muscle had been applied for eight other patients (Group II). Between 10 and 20 weeks after surgery, the patients underwent cranioplasty and dural healing evaluation by cerebrospinal fluid (CSF) leakage testing through the edge of the dural defect. The fibrocyte infiltration around the edge of the dural defect was examined histologically. Statistical analysis, using an independent t-test, was performed with a confidence interval of 95%. The results of the clinical and histological analysis suggest that an amniotic membrane graft was able to provide watertight dural closure and adequate fibrocyte infiltration comparable with that provided by temporalis muscle fascia. This study shows that using an amniotic membrane in neurosurgery has a potential advantage over an alternative dural healing.

Interhemispheric and Infratentorial Subdural Empyema with Preseptal Cellulitis as Complications of Sinusitis: A Case Report.

Intracranial complications of paranasal sinusitis have become rare due to the use of antibiotics nowadays. However, several cases have been reported due the ability of paranasal sinusitis to cause serious complications. Once the infection spreads over the cranial structure, it could infect the orbits, underlying bones, meninges, adjacent veins, and brain. Subdural empyema is a rare but potentially life-threatening complication following paranasal sinusitis and should be considered as a neurological emergency. The location where subdural empyema may appear is a challenge in diagnosis and treatment. We report the case of a 17-year-old boy who presented in a state of somnolence due to interhemispheric and infratentorial subdural empyema with preseptal cellulitis secondary to pansinusitis. Early diagnosis and aggressive antibiotic treatment combined with neurosurgical operation were mandatorily implemented. The case was managed using a multidisciplinary approach including the ENT, eye, and nutrition departments. The boy achieved clinical improvement, with impairment of eye movement as the only persistent symptom before discharge. Daily supervision at the primary health care center with continuous antibiotic treatment was recommended to the patient. Pertinent literature with controversies in the management of subdural empyema will be briefly discussed in this case report.
