Subdural hygromas are easily treated by trephination and drainage. Therefore, most neurosurgeons do not consider subdural hygromas seriously. However, various complications including intracerebral hemorrhage may develop after rapid drainage of subdural hygroma although rare. Postoperative intracerebral hemorrhage presents with a rapid deterioration of consciousness and focal neurological deficits occurring immediately after drainage of the subdural hygroma. The authors present an unfortunate massive intracerebral hemorrhage and pneumocephalus following drainage of the bifrontal subdural hygroma. The patient subsequently died. To prevent this disastrous complication, close neurosurgical observation and gradual drainage under a closed system seem mandatory. Possible pathogenic mechanisms for this unfavorable complication is discussed with a review of pertinent literatures.

Objective : There is no acceptable indication and treatment of choice for infantile and child subdural hygroma and there are only a few reports about that in Korea. So the authors studied the clinical findings of infantile and child patients with subdural hygroma to improve the understanding and to suggest a standard treatment method. Methods : The authors retrospectively evaluated the causes, preoperative symptoms, radiological thicknesses, and postoperative results of 25patients with subdural hygroma who received surgical therapy. Results : There were 16boys and 9girls whose median age was 6months[range $2{\sim}120months$]. The main clinical manifestations were seizures, increased intracranial pressure, macrocrania and alteration of consciousness. Radiological thicknesses of the subdural hygroma varied from 7mm to 42mm and postoperative changes of thickness[y] could be expressed with the factor of month[x]: $y\;=\;-1.32\;{\times}\;+11.8$ in subdural drainage, and $y\;=\;-1.52\;{\times}\;+14.9$ in subduroperitoneal shunts. Of the 25patients, 2 [50%] were successfully treated by aspiration, 13 [59%] by subdural drainage, and 9 [69%] by subduroperitoneal shunt. Conclusion : It is suggested that the diagnosis and treatment of subdural hygroma in infants and children should be carefully addressed because of its high prevalence in children, and especially in infants. It is also suggested that the subdural drainage could be primary initial treatment method because it is simpler than a shunt, and since our data show that there is no statistical difference in postoperative recovery duration between the two operative methods.

Background: Enlargement of subdural hematomas is relatively rapid in subacute stage of hematoma with clinical deterioration, which eventually necessitates surgery. The purpose of this study is to investigate the feasibility and safety of burr hole drainage using urokinase for management of patients with subacute subdural hematoma (SASDH). Methods: Nine patients with SASDH were treated by burr hole drainage using urokinase. Under local anesthesia a catheter was inserted into the hematoma through a burr hole. Burr hole drainage was followed by hematoma thrombolysis with instillation of urokinase (10,000 units) every 12 hours. Drainage was discontinued when a significant decrease of hematoma was observed on cranial computed tomography. Results: The patients' median age was 70 years (range, 62-87). The median Glasgow Coma Scale score before surgery was 15 (range, 11-15). Drainage was successfully performed in all patients. All patients had Glasgow Outcome Scale scores of 5 at discharge. There was no surgery-related morbidity or mortality. Conclusion: A burr hole drainage using urokinase could be a safe, feasible and effective minimally invasive method with low morbidity in treatment of selected patients with SASDHs.

Purpose: The objectives of this study are to classify chronic subdural hematomas based on brain computerized tomographic scan (CT scan) findings and to determine the mechanism of evolution and treatment methods. Methods: One hundred thirty-nine patients who were diagnosed with a chronic subdural hematoma and who available for follow up assessment 6 months post-surgery were analyzed retrospectively. The presence of trauma and past medical history were reviewed and evaluation criteria based on brain CT scan findings were examined. Results: Initial brain CT scans revealed a chronic subdural hematoma in 106 patients, a subdural hygroma in 24 patients, and an acute subdural hematoma in 9 patients. In all cases where the initial acute subdural hematoma had progressed to a chronic subdural hematoma, final was a hypo-density chronic subdural hematoma. In case where the initial subdural hygroma had progressed to a chronic subdural hematoma, the most cases of hematoma were hyper-density and mixed-density chronic subdural hematoma. In total, 173 surgeries were performed, and they consisted of 97 one burr-hole drainages, 70 two burr-hole drainages and 6 craniotomies. Conclusion: This study demonstrates that rebleeding and osmotic effects are mechanisms for enlarging of a chronic subdural hematoma. In most cases, one burr-hole drainage is a sufficient for treatment. However, in cases of mixed or acute-on-chronic subdural hematomas, other appropriate treatment strategies are required.

The purpose of this study was to contribute to the medical treatment of subdural effusion through clinical sequence analysis of patients who experienced improvement of subdural drainage and had a second operation for subdural drainage or subduroperitoneal shunt. Sixteen cases of the whole patients who have been underwent subdural effusion and subdural drainage were analyzed during the period from 2006 July to 2012 June. The study gave us a result that all of patients, who was taking aspirin, have been under the second operation(p<0.001) and these group have had a subduraoperitoneal shunt(p=0.014)). According to the comparative analysis for the patients group that divided into two; one had subduroperitoneal shunt and the other had no subduroperitoneal shunt, the outcomes of this study were shown as follows. First, their median line deviation was serious in their brain CT. In addition, their subdural effusion increased or did not change with a headache, vomiting, fever and dyspnea. As a result of those symptoms. subduraoperitoneal shunt was carried out(p=0.006). The surgical method for patients who were taken asprin must be cautiously selected and the prevention of sudden disappearance of cerebrospinal fluid and excessive change of intracranial pressure is very important in operation craniectomy.

Cerebellar hemorrhage is an unusual complication of supratentorial neurosurgery. To the best of our knowledge, only three case reports have described the occurrence of cerebellar hemorrhage after burr hole drainage for the treatment of chronic subdural hematoma (SDH). We present the case of a patient with this rare postoperative complication of cerebellar hemorrhage after burr hole drainage of a chronic SDH. Although burr hole drainage for the treatment of chronic SDH is rare complication, it is necessary to be aware of the possibility of cerebellar hemorrhage after supratentorial surgery, even with limited surgery such as burr hole drainage of a chronic SDH.

This article presents the case of a bilateral chronic subdural hematoma which was contaminated with Klebsiella pneumoniae and resulted in a life-threatening central nervous system infection. After repeated of bilateral burr-hole drainage, the patient became hyperpyrexic and drowsy. Suppuration within the subdural space was suspected and then the patient underwent bilateral fronto-temporo-parietal craniotomies, and pus was evacuated. Its cultures revealed Klebsiella pneumoniae. Intravenous meropenem was given for 6 weeks. He recovered completely. Microorganisms like Klebsiella pneumoniae may directly infect the subdural space with iatrogenic contamination.

We report a rare case of spontaneous spinal subdural hematoma[SSDH]. A 63-year-old man presented with radicular pain and paraparesis on both legs for several months. On magnetic resonance images, SSDH was found in lumbar region. Electrodiagnostic report showed bilateral lumbosacral polyradiculopathy, such as cauda equina syndrome. SSDH was drained with lumbar drainage at L4-5 level without direct exploration. The patient improved after drainage of the hematoma and then he was able to walk independently.

Background: Since the first report of a rapidly resolved subdural hemorrhage (SDH) in 1986, few additional case reports have been presented in the literature. Case Report: An 82-year-old female patient presented with a SDH over the left convexity. The SDH was removed via catheter drainage through a burr hole trephination. Post-operative computed tomography (CT) following 300 mL drainage from the chronic SDH demonstrated a newly developed SDH along the right convexity. A follow-up CT performed 2 hours later revealed an unexpected significant resolution of the acute SDH. Conclusion: The spontaneous resolution of acute SDH is believed to result from redistribution by washout of the hematoma by cerebrospinal fluid dilution. However, its exact pathophysiology is not well understood. When surgical evacuation is considered in acute SDH, conservative management should also be considered because spontaneous resolution of hemorrhage remains a possibility.
