이무숙,최병욱,최규옥,정남식 대한영상의학회 2007 Korean Journal of Radiology Vol.8 No.1

Transient left ventricular apical ballooning is characterized by transient wall motion abnormalities involving the left ventricular apex and mid-ventricle in the absence of coronary arterial occlusion. A 66-year-old woman presented to the emergency department with chest pain that mimicked acute myocardial infarction. An aortogram showed akinesis from the mid to apical left ventricle with sparing of the basal segments. Four days later, she underwent MRI, which demonstrated characteristic apical contractile dysfunction, the same as the aortogram, without evidence of myocardial infarction on the MRI. Two weeks later, her symptoms were resolved and follow-up echocardiography showed normal ventricular function.

Acute Ischemic Stroke in a 6-Year-Old Boy, Treated with Mechanical Thrombectomy: A Case Report

김기홍,이무숙,양태기 대한영상의학회 2016 대한영상의학회지 Vol.75 No.5

Pediatric acute ischemic stroke (AIS) is a relatively rare disease with an annual estimated incidence of 2.4–13 per 100000 children. However, pediatric AIS can lead to significant morbidity and mortality. Stroke in children differs from that in adults with respect to etiology, clinical presentation, or management. Therapeutic options for adult AIS are intravenous tissue plasminogen activator, intra-arterial pharmacological thrombolysis, and mechanical thrombectomy. However, management strategies for pediatric AIS, extrapolated largely from those of adult AIS, remain controversial. In this article, we present our experience in a boy with AIS, who was successfully treated with mechanical thrombectomy, by utilizing the Solitaire FR revascularization device.

비장애고등학생의 장애인식 조사 연구 -창원시 일반 고등학교 학생을 중심으로-

정대영,이무숙,하창완 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.7

In order to identify the disability awareness of high school students without disabilities and to provide basic data on integrated education, a survey was conducted for 570 high school students without disabilities in 36 classes of three regular high schools located in Changwon, Gyeongsangnam-do and 373 copies were used for the study. SPSS 25.0 program was used to carry out reliability analysis, frequency analysis, descriptive statistics analysis, independent sample T-test and one-way ANOVA for the collected data. The results and implications of the survey in this study are as follows: First, female students were found to have higher disability awareness than male students, and it is necessary to develop cyber education or to establish professional education courses in boys' schools to raise awareness of male students' disability awareness. Second, the awareness of students who have a lot of experience with students with disabilities or have volunteer experience for the disabled was found to be more positive. There should be many programs or systems that allow students to be naturally engaged through the curriculum rather than simple integration experience. In addition, it is necessary to activate volunteer club activities and visit to welfare institutions for the disabled. Third, the 'relationship principle with students with disabilities' was recorded the highest among the sub-factors of disability awareness, so programs should be developed in a variety of ways, such as cooperative learning, group strengthening, peer support, etc., in which students with and without disabilities can interact with each other. 본 연구는 비장애고등학생의 장애인식을 파악하여 통합교육에 대한 기초자료를 제공하기 위해 경남 창원시 소재 일반 고등학교 3개교 36학급의 비장애학생 570명을 대상으로 설문조사를 실시하였으며, 373부를 연구에 활용하였다. 수집된 자료는 SPSS 25.0 프로그램을 사용하여 신뢰도 분석, 빈도 분석, 기술통계분석, 독립표본 T검증과 일원배치 분산분석을 실시하였다. 본 연구의 설문조사 결과와 시사점은 다음과 같다. 첫째, 여학생이 남학생에 비하여 장애인식이 더 높게 나타났으며, 남학생의 장애인식을 높이기 위해 사이버교육 등을 개발하거나 남학교에 전문교육과정을 개설할 필요가 있다. 둘째, 장애학생과 활동 경험이 많거나 장애인에 대한 자원봉사활동 경험이 있는 학생들의 인식이 더 긍정적인 것으로 나타났다. 단순 통합 경험이 아닌 교육과정을 통해 자연스럽게 활동할 수 있는 여러 가지 프로그램이나 시스템이 마련되어야 한다. 또한, 봉사동아리 활동과 장애인 복지 기관 견학을 활성화해야 할 것이다. 셋째, 장애인식 하위 요인 중 ‘장애학생과의 관계 원칙’이 가장 높게 나왔으므로 장애학생과 비장애학생이 서로 상호작용할 수 있는 협동학습, 집단강화, 또래지원 등의 프로그램이 다양하게 개발되어야 할 것이다.

The Role of Interventional Radiology in Treatment of Patients with Acute Trauma: A Pictorial Essay

강경식,이무숙,김두리,김영환 대한영상의학회 2021 대한영상의학회지 Vol.82 No.2

Acute trauma is a common cause of mortality in individuals aged < 40 years. As organ preservation has become important in treating trauma patients, the treatment is shifting from surgical management to non-operative management. A multidisciplinary team approach, including interventional radiology (IR), is essential for the optimal management of trauma patients, as IR plays an important role in injury evaluation and management. IR also contributes significantly to achieving the best clinical outcomes in critically ill trauma patients. This pictorial essay aims to present and summarize various interventional treatments in trauma patients requiring critical care.

Minimally Invasive Treatment of Falciform Ligament Abscess in a 25-Day-Old Neonate: A Case Report

이민아,이정섭,이무숙,김승형,이경렬,김윤주,강기수 대한영상의학회 2018 대한영상의학회지 Vol.79 No.5

The falciform ligament is a hepatic suspensory ligament that extends from the umbilicus to the diaphragm, containing the ligamentum teres and a vestigial remnant of the umbilical vein. Among the rarely-occurring pathologies of the falciform ligament, which include ligament cyst, tumor, abnormal vascularization, and congenital ligament defect, a falciform ligament abscess is even more sporadic. Accordingly, the definitive diagnosis of the falciform ligament abscess is rather challenging and may easily be misinterpreted as an infected choledochal cyst or a liver abscess. We present a 25-day-old infant with the falciform ligament abscess, which developed after the umbilical venous catheter insertion and was successfully treated with percutaneous drainage and antibiotic administration.

Percutaneous Drainage and Povidone-Iodine Sclerotherapy of Cervical Lymphatic Malformation

김승형,송찬일,이무숙,임길채 연세대학교의과대학 2017 Yonsei medical journal Vol.58 No.6

Lymphatic malformations in cases with macrocystic lesions can be treated with surgical excision or sclerotherapy using alcohol, bleomycin, doxycycline, or OK-432. We report a case of a 24-year-old woman who underwent percutaneous drainage and povidone-iodine sclerotherapy as primary treatment for cervical lymphatic malformation. The patient underwent povidone-iodine sclerotherapy for 3 consecutive days. After 8 months, ultrasonography of the lesion in the neck revealed complete resolution of the cervical lymphatic malformation without any complication. Povidone-iodine sclerotherapy can be a safe and cost-effective treatment option for cervical lymphatic malformation.

장수연,김만득,이명수,이무숙,박성일,원종윤,이도연,이광훈 대한영상의학회 2012 Korean Journal of Radiology Vol.13 No.5

Objective: To evaluate the effectiveness of uterine artery embolization (UAE) for treating symptomatic fibroids with high signal intensity (SI) on magnetic resonance (MR) T2-weighted imaging (T2WI). Materials and Methods: A total of 537 cases, consisting of 14 patients with high SI fibroids on T2WI (T2 high group), were retrospectively included and compared with 28 randomly selected patients with low SI fibroids on T2WI (control group). High SI of a predominant fibroid on T2WI was defined as having the same or higher SI than the myometrium. Patient ages ranged from 28 to 52 years (mean, 38.1 years). All patients underwent MRI before and after UAE. Predominant fibroid and uterine volumes were calculated with MR images. Symptom status in terms of menorrhagia and dysmenorrhea was scored on a scale of 0-10, with 0 being no symptoms and 10 being the baseline, or initial symptoms. Results: Of the patients in the T2 high group, 13 out of 14 (92.9%) patients demonstrated complete necrosis of the predominant fibroids. The mean volume reduction rates of the predominant fibroids in the T2 high group was 61.7% at three months after UAE, which was significantly higher than the volume reduction rates of 42.1% noted in the control group (p < 0.05). Changes in symptom scores for menorrhagia and dysmenorrhea after UAE (baseline score minus follow-up score) were 4.9 and 7.5 in T2 high group and they were 5.0 and 7.7 in control group, suggesting a significant resolution of symptoms (p < 0.01) in both groups but no significant difference between the two groups. Conclusion: UAE is effective for uttering fibroids showing high SI on T2WI. The mean volume reduction rate of the predominant fibroids three months after UAE was greater in the T2 high group than in the control group.

Degeneration of Leiomyoma in Patients Referred for Uterine Fibroid Embolization: Incidence, Imaging Features and Clinical Characteristics

한승철,김만득,정대철,이명수,이무숙,박성일,원종윤,이도연,이광훈 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.1

Purpose: Imaging features and clinical characteristics of degenerated leiomyoma in patients referred for uterine fibroid embolization (UFE) were analyzed to assess the incidence of degenerated leiomyoma. Materials and Methods: Patients referred for UFE between 2008 and 2009 were retrospectively analyzed (n=276). Patients ranged in age from 27 to 51 years (mean 38.0 years). All patients underwent screening MRI with contrast enhancement. Medical histories and clinical symptoms were evaluated. Results: Among the 276 patients who underwent MRI, 14 (5.1%) showed degenerated leiomyomas. Symptoms were abdominal pain (n=4, 26.7%), menorrhagia (n=5, 35.7%) and bulk-related symptoms (n=5, 35.7%) and no symptoms (n=5, 35.7%). Of the 14 patients with degenerated leiomyomas,5 (42.9%) had a history of pregnancy in the past two years. For T1-weighted imaging (T1WI), a high signal intensity (SI) of the leiomyoma was the most common finding (n=9, 64.3%) and a hyperintense rim (n=4, 28.6%) was the second most common. On T2-weighted imaging (T2WI), a low SI of the leiomyoma was found in six patients (42.9%), a high SI in four (28.6%) and a heterogeneous SI in four (28.6%) patients. Conservative management was performed in 11 (78.6%) patients, surgery in 3 (21.4%) and uterine artery embolization in one (7.1%) patient. Conclusion: The incidence of degeneration of leiomyoma in patients referred for UFE was 5.1%. Patients presented with variable clinical symptoms with or without a history of pregnancy. MR imaging showed a high SI on T1WI and various SIs on T2WI without contrast enhancement. An understanding of the degeneration of leiomyomata is essential when considering UFE.
