Postoperative chylothorax is a rare occurrence after various thoracic surgical procedures, but it poses a substantial risk of morbidity and mortality. Thoracic duct embolization (TDE) is currently deemed the optimal treatment due to its safety and efficacy. This review offers an introduction to interventional options in this setting, detailing the steps of TDE for the edification of those engaged in postoperative care.

Objective: To investigate the changes of serum vascular endothelial growth factor (VEGF), soluble interleukin-2 receptor (SIL-2R) and hepatocyte growth factor (HGF) contents in patients with primary hepatocellular carcinoma (HCC) before and after percutaneous microwave coagulation therapy (PMCT) and determine their clinical significance. Materials and Methods: Fasting venous blood (3 mL) from 81 patients with primary HCC diagnosed by pathology was collected in the mornings 1 day before PMCT, and 1 day, 7 days and 1 month after PMCT, and then the serum was separated and stored in $-70^{\circ}C$. The contents of VEGF, SIL-2R and HGF were detected by enzyme linked immunosorbent assay (ELISA). Results: The serum VEGF, SIL-2R and HGF contents in 81 patients with primary HCC had obviously dynamic changes before and after PMCT. By comparison to 1 day after PMCT with pre-operation, there was no statistical significance regarding VEGF and SIL-2R contents (P>0.05), but HGF content showed significant difference (P<0.01). Compared with pre-operation, VEGF, SIL-2R and HGF contents 7 days and 1 month after PMCT all manifested significant differences (P<0.01). By comparison to 7 days with 1 month after PMCT, there was no statistical significance regarding the VEGF content (P>0.05), whereas SIL-2R and HGF contents showed significant change (P<0.01). Conclusions: The contents of serum VEGF, SIL-2R and HGF have obviously dynamic changes in primary HCC before and after PMCT, and their joint detection is expected to be an effective hematologic evaluation index of PMCT for primary HCC.

8년령의 중성화된 잡종 수컷 고양이 (증례 1)와 3년령의 중성화된 샴 수컷 고양이 (증례 2)가 뒷다리 마비, 지속적인 개구호흡, 그리고 객혈 등을 주증으로 내원하였다. 심잡음 (증례 1)과 분마성심음 (증례 2)이 좌측 심저부에서 청진되었으며, 방사선 검사상 증례 1의 경우 폐포패턴을 동반한 심한 공기연하증이, 증례 2에서는 확연한 심비대가 확인되었다. 심초음파 검사에서 두 마리 고양이 모두에서 좌심실과 심실중격의 구심성 비대와 좌심방의 확장이 확인되었다. 심장 초음파를 포함한 검사를 바탕으로 본 환축은 고양이 심근비대증으로 진단되었으며, 신체검사와 복부 초음파 검사를 통하여 병발한 안장색전증을 확인하였다. 일반적인 치료를 통한 환축의 예후가 불량한 점을 감안하여, 직접적인 혈관내 혈전용해술이 시도되었다. 혈관조영술을 통하여 혈전의 위치와 크기를 확인 할 수 있었으나, 광범위한 색전증으로 인하여 중재적 시술을 이용한 혈전용해는 성공적이지 못했다.

Diagnostic reference level (DRL) is employed to optimize the radiation doses of patients. The objective of this study is to review the DRLs for interventional procedures in Korea and abroad. Literature review was performed to investigate radiation dose index and measurement methodology commonly used in DRL determination. Dose area product (DAP) and fluoroscopy time within each major procedure category were systematically abstracted and analyzed. A wide variation was found in the radiation dose. The DAP values and fluoroscopy times ranged 0.01-3,081 Gy·㎠ and 2-16,878 seconds for all the interventional procedures, 8.5-1,679 Gy·㎠ and 32-5,775 seconds for the transcatheter arterial chemoembolization (TACE), and 0.1-686 Gy·㎠ and 16-6,636 seconds for the transfemoral cerebral angiography (TFCA), respectively. The DRL values of the DAP and fluoroscopy time were 238 Gy·㎠ and 1,224 seconds for the TACE and 189 Gy·㎠ and 686 seconds for the TFCA, respectively. Generally, the DRLs of Korea were lower than those of other developed countries, except for the percutaneous transluminal angioplasty with stent in arteries of the lower extremity (LE PTA and stent), aneurysm coil embolization, and Hickman insertion procedures. The wide variation in the radiation doses of the different procedures suggests that more attention must be paid to reduce unnecessary radiation exposure from medical imaging. Furthermore, periodic nationwide survey of medical radiation exposures is necessary to optimize the patient dose for radiation protection, which will ultimately contribute to patient dose reduction and radiological safety.

Purpose : This descriptive study was performed to analyze the trends of nursing interventional studies in adult nursing area. Method : All interventional studies of 'Journal of Korean Academy of Adult Nursing Society', fifty three articles, from 1989 to 2000 were collected and reviewed Result : The research subject were patients in 38(66.7%) and 81.8% of researches was performed in hospital environment. There was only one true experimental design and most of articles(79.2%) were designed by quasi-experimental method Only 17% of articles have theoretical framework and 73.6% of articles described research hypotheses. The data collection methods for variables were as follows: Psychosocial measurement 60.8%, physiological measurement 25.7%, and observation 13.5%, respectively. Lecture(16.7%), audio-visual(16.7%), and book, pamphlet, or leaflets(13.6%) were the most frequently used instruments of the interventions. Behavioral domain(60.3%) and Physiological: Basic domain(29.3%) was the most common, when the interventions were classified by Nursing Intervention Classification. Physiological(50.8%) and psychosocial variables(49.2%) were the two major dependent variables. Conclusion : Considering the above results obtained, the nursing intervention studies in adult nursing area have been tested with quasi-experimental studies through clinical trials. For the development of clinical nursing practice and advancement of nursing theories, the amount of interventional studies should be increased and the quality of research methods refined more to develop nursing science and practice in adult nursing area.

두경부 질환의 인터벤션 시술 시 시술자가 받는 피폭선량의 평가 및 감소연구를 위한 선행 연구로써, 이온 전리함을 이용하여 인터벤션 시술 시 시술자의 위치하는 공간선량 분포를 측정하였다. Bi-plane 인터벤션 시술 장비를 대상으로 4개 구역(45, 135, 225 그리고 315도)으로 나누어 가상의 시술자가 있다는 가정아래에 시술자의 결정장기위치에서 거리(80, 100, 120, 그리고 140 cm)에 따라 조사선량을 측정하였으며, 방사선발생장치의 위치를 변화시켜 선량변화를 분석하였다. 시술자의 대부분이 위치하는 225도의 구역의 조사선량은 가장 가까운 거리인 80 cm에서 시술자 눈의 높이에서 114.5 mR/h, 가슴의 높이는 143.1 mR/h, 그리고 생식기위치는 147 mR/h이었다. 그리고 방사선 발생장치의 위치를 시술자 가까이로 변화시켰을 경우, 평균적으로 $18.1{\pm}10.5%$의 선량이 증가하였다. 본 연구에서 인터벤션 시술 동안 시술자가 위치할 수 있는 곳의 공간선량분포를 확인하였으며, 본 연구 결과를 통하여 시술자의 방사선 방어에 대하여 구체적인 계획을 수립할 수 있을 것이라 사료된다.

C-arm fluoroscopy is a useful tool for interventional pain management. However, with the increasing use of C-arm fluoroscopy, the risk of accumulated radiation exposure is a significant concern for pain physicians. Therefore, efforts are needed to reduce radiation exposure. There are three types of radiation exposure sources: (1) the primary X-ray beam, (2) scattered radiation, and (3) leakage from the X-ray tube. The major radiation exposure risk for most medical staff members is scattered radiation, the amount of which is affected by many factors. Pain physicians can reduce their radiation exposure by use of several effective methods, which utilize the following main principles: reducing the exposure time, increasing the distance from the radiation source, and radiation shielding. Some methods reduce not only the pain physician's but also the patient's radiation exposure. Taking images with collimation and minimal use of magnification are ways to reduce the intensity of the primary X-ray beam and the amount of scattered radiation. It is also important to carefully select the C-arm fluoroscopy mode, such as pulsed mode or low-dose mode, for ensuring the physician's and patient's radiation safety. Pain physicians should practice these principles and also be aware of the annual permissible radiation dose as well as checking their radiation exposure. This article aimed to review the literature on radiation safety in relation to C-arm fluoroscopy and provide recommendations to pain physicians during C-arm fluoroscopy-guided interventional pain management.
