Biportal Endoscopic Posterior Cervical Foraminotomy for Adjacent 2-Level Foraminal Lesions Using a Single Approach (Sliding Technique)

허동화,하지수,장재원 대한척추신경외과학회 2023 Neurospine Vol.20 No.1

Objective: Endoscopic posterior cervical foraminotomy (PCF) using uniportal or biportal endoscopic approach has been performed for cervical foraminal stenosis or foraminal disc herniation. Two-level PCF is possible using a single biportal endoscopic approach. The purpose of this study was to present a technique of biportal endoscopic PCF for contiguous 2-level foraminal lesions using a single approach and its clinical results. Methods: Patients who received 2-level PCF using a single biportal endoscopic approach were enrolled in this study. We analyzed their clinical data including age, sex, complications, and Neck Disability Index (NDI), and visual analogue scale (VAS) of neck and arm. Postoperative magnetic resonance image was taken on the first postoperative day to determine whether there was sufficient decompression. Results: We successfully performed biportal endoscopic PCF for adjacent 2-level foraminal lesions using a single approach (sliding technique) in all 12 patients. There were cervical foraminal disc herniation with foraminal stenosis (5 cases) and 2-level foraminal stenosis (7 cases). Preoperative mean NDI and VAS of arm and neck significantly decreased at 12 months after surgery. Postoperative clinical outcomes were excellent in 5 patients, good in 6 patients, and fair in 1 patient. There was no major complication. Conclusion: Two-level PCF could be performed using a single approach biportal endoscopic surgery with only 2 skin incisions. Clinical outcomes are favorable. This sliding PCF technique using biportal endoscopic approach might be an alternative surgical treatment for contiguous 2-level cervical foraminal pathologic lesions.

뇌지주막하 출혈 후 중증 불응성 뇌혈관 연축에 대한 바비튜레이트 혼수요법

허동화,허철,조성민,황금,변진수,김헌주 대한신경외과학회 2003 Journal of Korean neurosurgical society Vol.33 No.2

Objective:This study is designed to evaluate the therapeutic effects and prognostic factors for barbituate coma therapy(BCT)in severe and refractory vasospasm following subarachnoid hemorrhage. Methods:Barbiturate coma therapy was used in 18 patients with severe and refractory vasospasm in spite of "3-H therapy" and intra-arterial papaverine infusion. The authors analyzed the clinical parameters including Glasgow Coma Scale(GCS), electroenceplographic finding, and brain computerized tomography(CT) scan findings in relation to outcome at discharge. Results:Among 18 patients, burst suppression pattern could be obtained in 17. In cases with good outcome, the duration elapsed from coma to drowsiness after BCT was 14.09±5.82 days and GCS score at this time was significant in the prediction of final outcome(p<0.05). Patients with ideal burst suppression pattern attainable more than 24 to 48 hours showed good outcome in 81.8%(p<0.05). The group that showed focal low density in the brain CT scan taken before BCT fared better prognosis compared with that of multifocal or diffuse low density(p<0.05), and patients with resolution of perimesencephalic cistern effacement on follow-up brain CT scan taken 48 hours after BCT showed better prognosis(p<0.05). Overall, 72.2% showed improvement of GCS score by 2 or more, and good outcome was noted in 50%. Conclusion:The barbiturate coma therapy seems to have a beneficial therapeutic effect on severe and refractory vasospasm and can be considered as a useful therapeutic modality. Key words:Subarachnoid hemorrhage;Vasospasm;Barbiturate coma therapy.

어머니의 색채예술 : 조각보와 수보를 중심으로

허동화 동아시아문화학회 2006 동아시아 문화와 예술 Vol.3 No.-

수보의 문양은 자연에서 도출된 것이나 일단 추상화 단계를 거치 세세한 부분을 사상하고 그 자연물의 이미지를 전달하는 데 필요한 최소한의 요소만을 남겨 절얀된 생물형태적인 선을 가지고 전체적으로 풍요로와 보이도록 구사되어 있다는 데서 그 특징을 찾을 수 있을 것이다. 이처럼 수보의 제작은 오랜 자수역사속에서 그 전통이 이어져오고 있는 것이다. 우리나라 자수가 시작 된 시기는 청동기 시대 즉, 기원전 1000년전으로 보고 있으며 그후 많은 변천을 거쳐 오늘에 이르고 있으나 감상용으로 제작하기보다는 실용자수의 전통이 이어져 온 것으로 다소 투박스러운 수명이 긴 자수의 제작을 선호해 온 것으로 보여진다. 우리나라 자수역사의 실체를 삼국시대 이전으로 봄으로써 수보의 역사 또한 삼국시대 이전으로 보아야 한다. 다만 보자기 일반의 역사는 그보다도 훨씬 더 오래 된 것으로 보아야 한다. 의식주 생활전반에서 다양하게 쓰여진 보자기는 수요가 많으면 생산과정에서 우수한 작품이 제작되게 마련이다. 그 중 자수보자기는 관동지방에서, 비단조각보자기는 호남지방에서, 모시조각보는 강화지방에서 많이 발달 해 왔다. 이상 살펴본 바에 의해 조각보와 수보는 하나의 생활소품이면서 예술적 평가의 대상으로서도 부족함이 없음을 알 수 있다.

Usefulness of Oblique Lumbar Magnetic Resonance Imaging for Nerve Root Anomalies and Extraforaminal Entrapment Lesions

허동화,김석우,Hsien-Hao Chang,박춘근 대한척추외과학회 2018 Asian Spine Journal Vol.12 No.3

Study Design: A retrospective review of prospectively evaluated magnetic resonance (MR) images. Purpose: Routine lumbar axial and sagittal MR images may not clearly demonstrate nerve root anomalies and entrapments in the extraforaminal region. Thus, lumbar extraforaminal lesions or nerve root anomalies may be underdiagnosed because of unfamiliar radiological anatomy. We aimed to investigate the clinical efficacy of our oblique magnetic resonance imaging (MRI) technique for diagnosing nerve root anomalies and entrapment lesions. Overview of Literature: Evaluation of clinical usefulness of oblique lumbar MRI for nerve root anomalies and extraforaminal entrapment lesions. Methods: In total, 162 patients (60 males and 102 females; mean age, 59.8±17.8 years) with suspected nerve root anomalies and entrapments in routine axial and sagittal MR images underwent unilateral or bilateral oblique lumbar T2-weighted MRI. The axial angle of the oblique image was parallel to the foramen. The oblique MRI findings of the symptomatic side were compared with those of the asymptomatic side in cases with unilateral pathologic lesions. Interobserver agreement was analyzed using kappa statistics. Results: The following abnormal findings were obtained: nerve root entrapment due to foraminal stenosis in 82 cases; extraforaminal disk herniation in 29; conjoined nerve root in six; and foraminal bony cyst in one. Forty-three of the 46 patients experienced unilateral lateralizing symptoms, unilateral nerve root entrapment due to foraminal stenosis, herniated disk, and extraforaminal bony cyst compared with the asymptomatic contralateral side (p <0.05). Conclusions: Our results suggest that oblique lumbar MRI is a simple and valuable modality for diagnosing anomalous lumbar nerve root lesions and entrapment.

보자기 문화

보자기는 우리나라의 고유한 생활용구로서 천-예외적으로 밥상이나 목판을 덮는 식지보(짧짧많) 의 경우 기름종이를 재료로 하고 있다을 사각형으로 잘라 만들어 썼다 보자기의 사용 범위는 극히 넓어 일상생활의 구석구석까지 미치지 않는 데가 없을 정도다. 밥상 보, 이불보, 햇대보 등의 용도로 일상생활에 소용되었음은 물론 흔례용 불교 의식용으로도 쓰였고 기우제를지낼 때 제단에 치거나조상의 영정(물觸)을셔뮤는등의 특수한용도로도사용되었다. 우리나라에서 보자기가 발달하게 된 원인은 여러 가지로 살펴 볼 수 있으나 우리나라는 위도상으 로 추운나라에 속하며 국토는 좁고 인구밀도는 높은 나라이며 천연자원이 적은 나라이다. 그러므로 주거공간이 낮고 좁은 것이 주생활의 일반적인 현상이었다. 이렇게 주거공간이 매우 협소했으므로 사용치 않을 때는 자리를 차지하지 않는 물건이 가재도구로서 바람직했다. 보A기는 개패에 따라 용 적의 신축이 자유로워 보관 혹은 운반 용구로 사용할 때는 용적을 최대한 이용하다가 사용하지 않을 때는 작게 접어둘 수 있으므로 그런 가재도구로서 적격이었다. 이런 편의 때문에 자연히 보자기가 널리 쓰이게 된 것으로 보인다.

Endoscopic Treatment of Extraforaminal Entrapment of L5 Nerve Root (Far Out Syndrome) by Unilateral Biportal Endoscopic Approach: Technical Report and Preliminary Clinical Results

허동화,Sagar Sharma,박춘근 대한척추신경외과학회 2019 Neurospine Vol.16 No.1

Objective: Far out syndrome is compression and entrapment of the L5 nerve root in the extraforaminal area between the hypertrophied L5 transverse process and the sacral ala. The purpose of this study was to describe the technique of unilateral biportal endoscopic decompression for far out syndrome and to analyze early clinical results after endoscopic decompression. Methods: The authors consecutively performed operative treatments for 16 patients with unilateral extraforaminal entrapment of the L5 nerve root (far out syndrome) using percutaneous biportal endoscopies. We included only patients who were followed more than six months after surgery. Demographic characteristics, operative time, concomitant herniated disc, and surgical complications were investigated. Clinical outcomes were evaluated using modified MacNab criteria, the visual analogue scale (VAS) for legs, and the Oswestry Disability Index (ODI). Results: Among 16 patients, a total of 14 cases with 4 males and 10 females were included in the study. The mean leg VAS and the ODI were significantly improved after unilateral biportal endoscopic surgery. Concomitant extraforaminal disc herniation was associated with a favorable outcome (p<0.05). Abdominal pain in the immediate postoperative period occurred in 2 patients. Abdominal pain was completely resolved with conservative management in both patients. Conclusion: We were able to achieve successful decompression of unilateral extraforaminal entrapment of the L5 nerve root using unilateral biportal endoscopic surgery. A unilateral biportal endoscopic approach may be considered as an alternative surgical treatment for far out syndrome.
