Burr hole drainage has been widely used to treat chronic subdural hematomas (SDH), and most of them are easily treated by simple trephination and drainage. However, various complications, such as, hematoma recurrence, infection, seizure, cerebral edema, tension pneumocephalus and failure of the brain to expand due to cerebro-cranial disproportion may develop after chronic SDH drainage. Among them, intracerebral hemorrhage after evacuation of a recurrent chronic SDH is very rare. Here, we report a fatal case of delayed intracerebral hemorrhage caused by coagulopathy following evacuation of a chronic SDH. Possible pathogenic mechanisms of this unfavorable complication are discussed and a review of pertinent literature is included.

Objective : We conducted this study to evaluate the clinical impact of early enteral nutrition (EN) on in-hospital mortality and outcome in patients with critical hypertensive intracerebral hemorrhage (ICH). Methods : We retrospectively analyzed 123 ICH patients with Glasgow Coma Scale (GCS) score of 3-12. We divided the subjects into two groups : early EN group (< 48 hours, n = 89) and delayed EN group ($\geq$ 48 hours, n = 34). Body weight, total intake and output, serum albumin, Creactive protein, infectious complications, morbidity at discharge and in-hospital mortality were compared with statistical analysis. Results : The incidence of nosocomial pneumonia and length of intensive care unit stay were significantly lower in the early EN group than in the delayed EN group (p < 0.05). In-hospital mortality was less in the early EN group than in the delayed EN group (10.1% vs. 35.3%, respectively; p = 0.001). By multivariate analysis, early EN [odds ratio (OR) 0.229, 95% CI : 0.066-0.793], nosocomial pneumonia (OR = 5.381, 95% CI : 1.621-17.865) and initial GCS score (OR = 1.482 95% CI : 1.160-1.893) were independent predictors of in-hospital mortality in patients with critical hypertensive ICH. Conclusion : These findings indicate that early EN is an important predictor of outcome in patients with critical hypertensive ICH.

While a delayed intracerebral hemorrhage at the site of a ventricular catheter has occasionally been reported in literature, a delayed hemorrhage caused by venous infarction secondary to ventriculoperitoneal shunting has not been previously reported. In the present case, a 68-year-old woman underwent ventriculoperitoneal shunting through a frontal burr hole, and developed a hemorrhagic transformation of venous infarction on the second postoperative day. This massive venous infarction was caused by bipolar coagulation and occlusion of a large paramedian cortical vein in association with atresia of the rostral superior sagittal sinus. Thus, to eliminate the risk of postoperative venous infarction, technical precautions to avoid damaging surface vessels in a burr hole are required under loupe magnification in ventriculoperitoneal shunting.

Blunt carotid artery injury is uncommon, yet not rare. However, it is often underdiagnosed because of inconsistent early symptoms or masking by the presence of coexisting brain and spinal injuries. The delay between the accident and the onset of cerebral ischemic symptoms is variable and has been reported to range from minutes to ten years. However, to our knowledge, there has been no report on a case presented with delayed intracerebral hemorrhage 25months after blunt carotid artery injury. We report on a case with discussion of supporting evidence and possible mechanisms.

Here, we report a rare case of an anaplastic astrocytoma masquerading as a hypertensive basal ganglia hemorrhage. A 69-year-old woman who had been under medical management for hypertension during the past 3 years suddenly developed right hemiparesis with dysarthria. Brain computed tomography (CT) scans with contrast and CT angiograms revealed an intracerebral hemorrhage (ICH) in the left basal ganglia, without an underlying lesion. She was treated conservatively, but underwent a ventriculoperitoneal shunt operation 3 months after the initial attack due to deteriorated mental status and chronic hydrocephalus. Three months later, her mental status deteriorated further. Magnetic resonance imaging (MRI) with gadolinium demonstrated an irregular enhanced mass in which the previous hemorrhage occurred. The final histological diagnosis which made by stereotactic biopsy was an anaplastic astrocytoma. In the present case, the diagnosis of a high grade glioma was delayed due to tumor bleeding mimicking hypertensive ICH. Thus, a careful review of neuroradiological images including MRI with a suspicion of tumor bleeding is needed even in the patients with past medical history of hypertension.

Delayed traumatic intracerebral hemorrhage (DT-ICH) is a rare event in head trauma patients. However, it develops unexpectedly and results in very severe brain damage. Thus, close monitoring of the neurologic status is needed for every trauma patient. Sometimes, however, neurologic monitoring cannot be done because of sedation, especially in cases of abdominal surgery. In this case report, we describe the case of a 37-yr-old, male patients who had hemoperitoneum because of spleen and renal injury. At the initial operation, massive bleeding was found, so gauze-packing surgery was done first. After the first operation, we sedated the patient for about two days, after which the packed gauze was removed, and the abdominal wound was closed. Immediately after the second operation, we found pupil dilation. Emergent CT was performed. The CT revealed DT-ICH with severe brain edema and midline shifting. However, the patient condition deteriorated progressively despite emergency operation, he expired 2 days after hematoma evacuation.

Purpose: Recent developments in minimally invasive techniques have the potential to reduce surgical morbidity, promote patient recovery, accelerate surgical procedures, and thus improve cost-effectiveness in case management. In this study, we compared the treatment efficacy and results of supraorbital keyhole approach (SOKA) with those of conventional unilateral frontal craniotomy (CUFC) for traumatic intracerebral hemorrhage (TICH) in the frontal lobe. Methods: We analyzed the data of 38 patients who underwent CUFC (n=30) and SOKA (n=8) and retrospectively reviewed their medical records and radiological findings. Furthermore, we tried to identify the best surgical method for such lesions by including patients who underwent burr hole aspiration and drainage (BHAD) (n=9) under local anesthesia due to various circumstances. Results: The difference in the initial Glasgow coma scale score, operative time, and length of hospitalization between the CUFC and SOKA were statistically significant. All radiological features between the two groups including associated skull fracture, amount of pre- and postoperative hematoma, percentage of complete hematoma removal, pre- and postoperative midline shifting of the hematoma, and development of postoperative delayed hematoma were not statistically significant. Our experience of 46 patients with TICH in the frontal lobe with any of the three different surgical methods including BHAD enabled us to obtain valuable findings. Conclusions: Although it is difficult to insist that one particular approach is more useful than the other, we are confident that SOKA will have more advantages over CUFC in carefully selected patients with frontal TICH depending on the surgical experience of a neurosurgeon.

Vasoconstriction of intracerebral arteries is the leading cause of delayed cerebral infarction and mortality following aneurysmal subarachnoid hemorrhage. Transcranial Doppler studies show and increase in the flow velocities of basal cerebral arteries, which usually start around day 4 following a subarachnoid hemorrhage, and peaking by days 7 to 14. Angiographic studies confirm the presence of at least some degree of MCA vasospasm when the flow velocities are higher than 100 cm/sec. Mean velocities in the 120 to 200 cm/sec range correspond to 25 to 50% luminal narrowing. MCA and ACA vsospasm is detected with around 90% specificity. Sensitivity is 80% and 50% respectively. A 200cm/sec threshold and rapid flow velocity increase exceeding 50 cm/sec on consecutive days, has been associated with subsequent infarction. Transcranial Doppler is also used to monitor the effects of endovascular treatment of vasospasm. Flow velocities decrease following successful angioplasty or papaverine infusion. Overall, transcranial Doppler studies are considered to have acceptable accuracy for the evaluation of vasospasm in aneurysmal subarachnoid hemorrhage, with limitations that have to be taken into consideration in the clinical setting.

Traumatic intracranial aneurysms are rare, compromising less than 1% of intracranial aneurysms. The case of 20-year-old man suffered from delayed frontal intracerebral hematoma, subarachnoid hemorrhage and intraventricular hemorrhage from traumatic pericallosal aneurysm 12 days after head injury is presented. Traumatic pericallosal artery aneurysm is always near the falcine edge, is unrelated to arterial branching point. Sudden movement of brain and artery causes vessel wall injury against the stationary edge of the falx. Because of high mortality rate of ruptured traumatic aneurysm, clinical suspicion must be focused on the prompt diagnostic work-up and early treatment.

Traumatic pseudoaneurysms of the middle meningeal artery (MMA) are rare phenomenon, which are usually associated with head trauma such as an underlying skull fracture. They were usually known to cause acute or delayed epidural hematomas but can be associated with subdural, subarachnoid, or even intracerebral hemorrhage. Sometimes, a high mortality rate was reported in these circumferences. But the natural course of these pseudoaneurysms is not well recognized. The indication and guideline of treatment for pseudoaneurysm are also unclear. This report describes a rare case of angiographically progressive change of traumatic pseudoaneurysm of the middle meningeal artery for one week, which was treated with endovascular embolization.
