Objective : Aneurysmal rebleeding is a major cause of death and disability.The aim this study to investigate the incidence rebleeding, factors related with patient's outcome.Methods During period 12 years, from September 1995 August 2007, 492 consecutive patients aneurysmal subarachnoid hemorrhage (SAH) underwent surgery at our institution.We reviewed clinical records, radiologic findings, possible inducing rebleeding.Also, we statistically analyzed various between favorable outcome group...
Artifacts introduced by stents limit the value of magnetic resonance (MR) imaging as a follow-up modality after stent-assisted coil embolization cerebral aneurysms.To investigate usefulness 3 Tesla (3T) time-of-flight (TOF) MR angiography (MRA) for evaluation.Twenty-two aneurysms 20 patients treated with were followed up 3T TOF MRA and digital subtraction (DSA) three-dimensional rotational (3DRA). The status coiled was compared DSA 3DRA in terms complete occlusion, residual neck, aneurysm....
With the aim of providing effective periodontal therapeutic modality, drug-releasing membranes for guided tissue regeneration (GTR) were developed. As GTR membranes, biodegradable barrier composed porous poly(L-lactide) (PLLA) films cast on poly(glycolide) (PGA) meshes fabricated using an in-air drying phase inversion technique. PLLA was dissolved in methylene chloride-ethylacetate mixtures, knitted PGA mesh, and then air-dried. Tetracycline, which is used therapy because its antibacterial...
Although endovascular technique and related devices continue to improve, recanalization of embolized aneurysm remains a pitfall this approach. The problem how treat the recanalized needs be addressed.To determine outcomes patients undergoing repeat embolization for intracranial aneurysms evaluate impact stent implantation on subsequent recanalization.Between September 2001 2011, we performed retreatment in 162 with total 197 aneurysms. Stent was 68 during retreatment. Clinical morphological...
BACKGROUND: Protection techniques using stents or microcatheters allow treatment of aneurysms with complex configurations by coil embolization. However, the application these is occasionally limited in wide-neck middle cerebral artery (MCA) acute angularity efferent branch vessel. OBJECTIVE: We describe a looping technique for passage microcatheter and microwire into acutely angled vessel without navigating system through aneurysm lumen. METHODS: To select angulated branch, looped was...
Treatment with mesenchymal stem cells (MSC) in spinal cord injury (SCI) has been highlighted as therapeutic candidate for SCI. Although astrogliosis is a major phenomenon after SCI, the role of still controversial. In this study, we determined whether acute transplantation MSC improves outcome SCI through modulating astrogliosis.Bone marrow derived rat MSCs were induced neural differentiation and transplanted rats. Matrix metalloproteinase (MMP) neuro-inflammatory pathway analyzed at 1, 3 7...
We conducted retrospective collection of demographic, clinical, and radiographic data in 59 patients who underwent a first cranioplasty following decompressive craniectomy during period 6 years, between January 2004 December 2009.Patients for the control increased intracranial pressure.The decision to undertake depended on judgment each individual surgeon.Although operative techniques were different among neurosurgeons, bone flaps removed initial frozen stored bank.The previous scars...
Although cavernous hemangiomas occur frequently in the intracranial structures, they are rare spine. Most of spinal vertebral origin and "pure" epidural not originating from bone very rare. Our hemangioma case is extremely because its involvement intralesional hemorrhage. A 64-year-old man presented with progressive paraparesis two months ago. His motor weakness was rated as grade 4/5 bilateral lower extremities. He also complained decreased sensation below T4 sensory dermatome, which...
The aim of this study was to analyze the treatment outcome patients with vein Galen aneurysmal malformations (VGM).Clinical and angiographic data six consecutive VGM were retrospectively reviewed. VGMs angiographically classified by Yasargil's method. Treatment outcomes evaluated.Mean age at initial 4.4±5.7 months. Angiographic types type II in two III four. Three had cardiac symptoms others asymptomatic. Two treated transvenous embolization, three transarterial one managed conservatively....
We aimed to develop a cloud-based telemedicine platform for patients with intracerebral hemorrhage (ICH) at local hospitals in rural and underserved areas Gangwon-do using artificial intelligence non-face-to-face collaboration treatment technology. This is prospective multi-center development project which neurosurgeons from four university Gangwondo will participate. Information technology experts verify improve the performance of while treating ICH actual medical field. Problems identified...
Intraoperative ventriculostomy is widely adopted to make the slack brain. However, there are few reports about hemorrhagic or parenchymal injuries after ventriculostomy. We tried analyze and investigate incidence of these complications in a consecutive series patients with aneurysmal subarachnoid hemorrhage (SAH).From September 2006 June 2007, 43 underwent surgical clipping for SAH at our hospital. Among patients, we investigated intraoperative using postoperative computed tomographic scan...
Abstract: Traumatic subarachnoid hemorrhage (SAH), a common finding following head trauma, is usually benign condition with favorable outcome, seldom requiring surgical intervention. Unlike nontraumatic aneurysmal SAH, most cases of traumatic SAH occur in the sulci cerebral convexities, and only rarely arise at base brain. Basal can be life-threatening primarily associated rupture vertebrobasilar arteries. We herein present rare case basal resulting from posterior communicating artery...
The purpose of this study is to investigate the correlation between various transcranial Doppler (TCD) ultrasonography parameters and clinical vasospasm after aneurysmal subarachnoid hemorrhage (SAH).This enrolled 40 patients presented with SAH September 2006 August 2007. We measured differences mean blood flow velocity (BFVm), highest systolic (BFVh), Lindegaard ratio (LR) in middle cerebral artery on TCD examination. These were evaluated for by univariate analysis receiver operating...
