BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

Object : This study was conducted to evaluate the surgical results of the active treatment of unruptured intracranial aneurysms (UIAs) and to suggest treatment indications. METHODS: Operations were performed on 49 patients with 52 UIAs between 1999 and 2005. Medical records and radiologic studies of the patients with UIAs were retrospectively reviewed. The clinical outcomes were evaluated in each patient by the modified Glasgow Outcome Scale (m-GOS) one month after operation. RESULTS: UIAs had a high frequency of a middle cerebral artery (MCA) and an internal carotid artery (ICA) aneurysm. Forty-four UIAs (84.6%) ranged between 5 mm to 15 mm in diameter. Fortysix UIAs were treated by clipping, 2 by wrapping, and coil embolization was used in 3 UIAs. In one patient, which had only one UIA, one procedure and one operation was performed. There was no surgical mortality. In most patients, surgical complications or neurological deteriorations were not found. In three patients, minor neurological deficits of ptosis (2 patients) and spinal subdural hematoma (1 patient) were newly developed after operation. However the patients completely recovered within 3 months after operation. Finally, the surgical mortality and morbidity rate was 0%. CONCLUSION: If the UIAs are larger than 5 mm in diameter and located in a susceptible area for rupture, surgical treatment should be considered for the UIAs. If operation is performed by an expert neurosurgeon, surgical clipping is one of the best treatment modalities with or without endovascular treatment.

Obstruction of the common bile duct (CBD) by direct extension of a tumor is occasionally found in patients with a hepatic neoplasm, but a bile duct tumor embolus caused by intrabiliary transplantation of a free floating tumor is a rare complication of a hepatocellular carcinoma. A patient of ours was recently observed with a fragment of tumor from a primary hepatocellular carcinoma (HCC) that obstructed the distal CBD. A-46-year-old man was admitted to our hospital with a distal CBD mass, measuring 1.2x1.5 cm, found by a biliary computed tomography (CT) scan. Four month prior to his admission, he had undergone a right hemihepatectomy for a HCC accompanied by direct intrahepatic bile duct invasion, without obstructive jaundice. On admission, there were no abnormal findings in the physical and laboratory examinations. An Endoscopic retrograde cholangiopancreatography and papillotomy had been performed, which showed an irregular shaped filling defect in the distal CBD. Endoscopic nasobiliary drainage (ENBD) was carried out for biliary decompression. Partially extracted soft tissue from the CBD by ERCP revealed a HCC. On performed a pylorus- preserving pancreaticoduodenectomy, a 1cm sized tumor remnant was found attached to the mucosa of the intrapancreatic portion of the bile duct, but without any invasive growth into the submucosa. The tumor may have been an intrabiliary transplantation from the HCC in the right lobe through the bile duct. When an obstructive mass is found in the distal CBD, tumor embolus should be considered, and a radical pancreaticoduodenectomy can be adopted as a safe and effective treatment modality.

Familial intracranial aneurysm is rare. We have clipped two posterior circulation intracranial aneurysms in mother and son. Mother was 48 years old and presented with severe headache and drowsy mentality. A basilar artery bifurcation aneurysm was found on DSA(digital subtraction angiography) and successfully clipped with transsylvian pterional approach. Her son was 24-year-old and presented with seizure and drowsy mentality. An aneurysmal sac was found on the bifurcation of vertebral artery and posterior inferior cerebellar artery. We have clipped it successfully with far lateral suboccipital approach. The authors recommended the use of screening test, such as MRIand high resolution CT, on the group of patients with the characteristic features of familial intracranial aneurysm.

Spinal subdural hematoma(SSDH) is rare disease. Furthermore, it rarely occurs as a complication of intracranial surgery. There are few case reports which describing SSDH after craniotomy. Although the exact pathogenetic mechanism is obscure, some investigators propose that downward migration of intracranial hematoma by the effect of gravity is one of the cause of SSDH, and which is commonly suggested. But others propose that cerebrospinal fluid(CSF) hypotension is an another possible mechanism. In this paper, we report two cases of SSDH after clipping of an aneurysmal neck.

OBJECTIVE: To determine the relationship between the clinical outcome and the extent of surgical laminectomy for adequate decompression on the cases of cauda equina syndrome, the authors review and analyze their cases and compared with those of literatures. METHODS: The authors reviewed 655 patients retrospectively who had underwent surgery on the cases of lumbar disc herniation from January 2000 to December 2004. There were 19 patients (2.9%) who presented for clinical cauda equina syndrome. Among them, we selected and analyzed 15 patients who were treated by unilateral partial hemilaminectomy with discectomy or bilateral partial laminectomy with discectomy, and they had been followed from 5 weeks to 47 months postoperatively (mean, 13.47 months). The levels of the disc herniations were L4-5 in 8 patients, following L5-S1 in 4 patients and 2 levels(L4-5 and L5-S1) in 3 patients. Motor and sensory recoveries were recorded. Postoperative urinary function recovery was defined according to Gleave and Macfarlane7). RESULTS: In 12 months postoperatively, the bladder function was obtained in 14 of 15 patients(93%) with regaining urinary continence. Thirteen of 15 patients(86%) with preoperative motor weakness of lower extremities were recovered. Sensory deficit of lower extremities, perianal and saddle anesthesia were all recovered. Patients had recovered on lumbosciatic pain and saddle hypesthesia, in turn, motor function and urinary incontinence. CONCLUSION: In treating cauda equina syndrome, the authors did less extensive surgery, such as unilateral partial hemilaminectomy with discectomy or bilateral partial laminectomy with discectomy for adequate decompression. The outcome is satisfactory and comparable with those of subtotal or total laminectomy.

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease. Pathologic changes occurred in patients with AS result in a weakened vertebral column with increased susceptibility to fractures, even though a trivial injury. Fractures usually tends to involve the lower cervical spine, but rarely, they are also occurred in thoracolumbar spine. We present our experiences of three cases of spinal fracture in patients with AS, cervical, thoracic, and lumbar spine, with a review of literatures.

OBJECTIVES: We aimed to develop a common health information exchange (HIE) platform that can provide integrated services for implementing the HIE infrastructure in addition to guidelines for participating in an HIE network in South Korea. METHODS: By exploiting the Health Level 7 (HL7) Clinical Document Architecture (CDA) and Integrating the Healthcare Enterprise (IHE) Cross-enterprise Document Sharing-b (XDS.b) profile, we defined the architectural model, exchanging data items and their standardization, messaging standards, and privacy and security guidelines, for a secure, nationwide, interoperable HIE. We then developed a service-oriented common HIE platform to minimize the effort and difficulty of fulfilling the standard requirements for participating in the HIE network. The common platform supports open application program interfaces (APIs) for implementing a document registry, a document repository, a document consumer, and a master patient index. It could also be used for testing environments for the implementation of standard requirements. RESULTS: As the initial phase of implementing a nationwide HIE network in South Korea, we built a regional network for workers' compensation (WC) hospitals and their collaborating clinics to share referral and care record summaries to ensure the continuity of care for industrially injured workers, using the common HIE platform and verifying the feasibility of our technologies. CONCLUSIONS: We expect to expand the HIE network on a national scale with rapid support for implementing HL7 and IHE standards in South Korea.

OBJECTIVE: A variety of factors are known to have an influence on the recurrence of chronic subdural hematoma (CSDH). In this study, the authors investigated the influential factors for recurrence of CSDH after burr hole drainage. METHODS: 45 patients with unilateral CSDH were treated with one-burr hole trephination and closed drainage in our hospital during last 6 years, whom the drainage catheter tip was randomly located and checked on postoperative computed tomography (CT). The clinical status of patients, thickness of hematoma, midline displacement of before and after surgery, amount of subdural air collection, drainage catheter tip location were estimated and the relationship of those factors with the recurrence was analyzed. RESULTS: Patients with located catheter tip in frontal had a better clinical and radiological result. And the recurrence of CSDH was lower who has lesser amount of subdural air collection in postoperative CT. CONCLUSION: The recurrence rate of unilateral CSDH is influenced by the location of drainage catheter tip and the amount of subdural air collection.

Primary leptomeningeal malignant melanoma is rare entity. We present a case of primary leptomeningeal malignant melanoma of 66-year-old male, who had suffered severe headache, confusion, and right hemiparesis. The brain computed tomography and magnetic resonance image revealed a well enhancing mass with hemorrhage in the left fronto-parietal region. Total surgical removal of the lesion was performed without neurological deficit. He died at home 6 months after operation. Probably, it seems that the cause of death was poor general condition due to obtunded mentality or brain herniation due to increased intracranial pressure. The literature on this subject is briefly reviewed.
