研究室紹介
Professor Cheon Sik Choi's research lab specializes in cerebrovascular interventions, with a primary focus on the endovascular treatment of complex intracranial aneurysms, particularly ruptured blood blister-like aneurysms (BBAs) and dissecting aneurysms of the vertebrobasilar system. The lab emphasizes innovative endovascular techniques such as stent-assisted coil embolization and stent-within-a-stent procedures to achieve aneurysm occlusion while preserving parent vessel patency. Their work also extends to the management of subarachnoid hemorrhage and postoperative complications, including chronic subdural hematoma and fever of unknown origin in neurosurgical patients.

15OBJECT: Ruptured blood blister-like aneurysms (BBAs) of the internal carotid artery (ICA) are rare but carry a high rate of morbidity and mortality. Furthermore, BBAs are very difficult to treat surgically as well as endovascularly. The authors present their experience in treating BBAs with reconstructive endovascular methods. METHODS: Nine ruptured BBAs in 9 consecutive patients (2 men and 7 women; mean age 50 years, range 42-57 years) were treated using reconstructive endovascular methods betw
Ruptured blood blister-like aneurysms (BBAs) of the internal carotid artery (ICA) are potentially dangerous lesions because of the high risk of intraoperative bleeding associated with their wide fragile neck. The authors discuss cases in which BBAs were treated endovascularly during the chronic stage and report a case in which a ruptured BBA of the ICA was successfully treated in the acute phase with stent-assisted coil embolization and a subsequent stent-within-a-stent procedure.
OBJECT: A ruptured dissecting aneurysm of the vertebrobasilar artery (VBA-DA) is a well-known cause of acute subarachnoid hemorrhage (SAH) with a high rate of early rebleeding. Internal trapping of the parent artery, including the dissected segment, is one of the most reliable techniques to prevent rebleeding. However, for a ruptured VBA-DA not suitable for internal trapping, the optimal treatment method has not been well established. The authors describe their experience in treating ruptured VB
The operation may be delayed in high- and mixed-density groups, unless severe symptoms or signs are present. In addition, placing the catheter tip at the frontal area helps to reduce the incidence of postoperative recurrence of CSDH and to increase the BRR.
PCT may be useful in the diagnosing neurosurgical patients with postoperative fever of unknown origin.
A 10-year-old female patient presented with a rapidly growing nodular mass lesion on her right frontal area. On skull radiography and computed tomography (CT) imaging, this mass had a well-demarcated punch-out lesion with a transdiploic, exophytic soft tissue mass nodule on the frontal scalp. Magnetic resonance (MR) imaging revealed the presence of a 1.5×1.2×1 cm sized calvarial lesion. This lesion was hypointense on T1 and heterogenous hyperintense on T2 weighted MR images, and exhibited hetero
Theses results suggest that increased serum cTnT level at admission is associated with in-hospital mortality and the addition of a serum cTnT assay to routine admission testing should be considered in patients with ICH.
Objective : Classical markers of infection cannot differentiate reliably between inflammation and infection after neurosurgery. This study investigated the dynamics of serum procalcitonin (PCT) in patients who had elective spine surgeries without complications. Methods : Participants were 103 patients (47 women, 56 men) who underwent elective spinal surgery. Clinical variables relevant to the study included age, sex, medical history, body mass index (BMI), site and type of surgery, and surgery d
The authors present a rare case of severe vasospasm following the rupture of arteriovenous fistula. On initial CT scan, hematoma in the corpus callosum and left inferior frontal region with surrounding cerebromalacia and all ventricles without apparent subarachnoid hemorrhage were seen. Angiograms showed arterivenous fistula but did not show cerebral vasospasm. Thirteen days after admission the neurological state of patient suddenly deteriorated and bilateral motor weaknesses developed. Followin
Multiple OSAC is feasible and effective for complex aneurysms and recurrent aneurysms after stent-assisted coiling.
Spinal epidural lipomatosis (SEL) is an abnormal localized accumulation of fat tissues in the epidural space. It is strongly related with steroid administration. The symptoms of SEL are various and range from back pain to paraplegia. In severe cases, decompressive laminectomy is the choice of treatment. A 32-year-old woman who had been under long-term steroid administration after suprasellar tumor resection was admitted for both leg radiating pain and weakness. She was diagnosed with SEL and had
OBJECTIVE: Bisphosphonate, a typical bone resorption inhibitor, is an important first-line drug for treating osteoporosis. Recent studies show a novel paradigm in stimulating bone formation. Teriparatide, which is composed of recombinant human parathyroid hormone, stimulates osteoblasts and induces bone regeneration. Bone mineral density (BMD) that was used before and after the treatment with anti-osteoporosis drug was compared for the effectiveness in therapy between a combination of teriparati
성혼(成渾)은 일반적으로 이황(李滉)의 철학과 이이(李珥)의 철학을 절충한 사람으로 평가받고 있다. 성혼은, 감정이 아직 일어나지 않았을 때부터 인심과 도심의 싹이 나뉘어 있는 것은 아니지만 감정이 일어나는 순간 인심과 도심이 동시에 발출한다는 견해를 제시했다. 미발(未發)에 관한 언급은 이이의 기발리승일도설(氣發理乘一途說)과 같고 이발(已發)에 관한 언급은 이황의 호발설(互發說)과 유사해 보이기 때문에, 이것이 성혼의 철학을 이황 철학과 이이 철학의 절충으로 보는 주요한 근거가 되었다. 그러나 이이의 기발리승일도설과 이황의 호발설은 각각 미발과 이발을 관통하는 이론이어서 미발과 이발로 절단할 수도 없고, 또 두 명제가 모순관계에 놓여있기 때문에 두 명제를 절충할 수도 없다. 이황의 호발설이 담고 있는 의미를 호발(互發)과 상수(相須)로 나누어 그 대응관계를 살펴보면, 호발과 모순관계에 놓여 있는 것은 성심정의일로설(性心情意一路說)이고, 상수와 모순관계에 놓여있는 것은 기발리승일도설
