In the radiology department, where radiation is used in medical institutions to perform examinations with various equipment, the field of surgical treatment is the intervention angiography room. Accordingly, strict infection control is required. The purpose of this study was to determine the contamination status by detecting pathogens before and after disinfection in the intervention angiography room, and to determine the degree of death by using a disinfectant, sodium dichloride isocyanurate, which is mainly used in the intervention angiography room. The subjects were 10 medical institutions of general hospital level or higher with an intervention angiography room in the P city, and 12 places with high contact frequency during examinations and procedures were sampled and requested to an analysis institution. As for the sample collection method, up/down, left/right directions were used to increase precision. Before disinfection, all procedures were completed, and after disinfection, exposure was performed using a disinfectant for at least 10 minutes, and detection was performed using a transport medium. As a result, in the pathogen analysis, most pathogens were detected in a humid environment or in a place with high contact frequency for microorganisms to thrive. The detected pathogens were found in the general environment or were human flora. It is a pathogen that does not cause disease under normal healthy host conditions. However, it was found to be an opportunistic infection that causes opportunistic infection depending on the case or situation in which the body's resistance is weakened. In addition, as a result of using the disinfectant mainly used in the intervention angiography room, it was found that more than 93.3% of them died. Therefore, the data of this study will be used as good basic data for the evaluation of pathogens in the intervention angiography room and will be of great help in infection control.

Angiography means that a check up to know an abnormal condition in all the blood vessels include from the heart, aortae, cerobrovascular and abdonominal artery to hands and feet. Main examples of this are cerebral angiography, abdominal, liver for urinary anomaly, renovascular angiography, and artery and vein in arms and legs. Angiography uses radial rays or angiography equipment for an image output during interventional procedure and compositive diagnosis. The acts which performed in a projection room have changed drastically. In general, it is performed by using equipment which is attached one or two C-arms and the method of inserting catheter in vein after anesthesia. For this reason, some rooms that consist of angiography room units should be planned not only for expensiveness equipment and facilities also to be germ-free. Nowadays, in the angiography unit case, it is placed independently as the central part of many hospitals. It does not belong to the imaging medical department any more as considering raising filming times and the relation between C.C.U.(coronary care unit) and operation unit. This means the acts performed are diversified and well-organized rooms in support of diagnosis are required. However, it is difficult to plan the angiography room unit due to domestic researches and data on this unit are not enough. Therefore, this study aims at bringing up basic issue for architectural planning of the angiography unit in general hospital.

본 연구는 설문조사를 통해 혈관조영검사실 종사자의 감염관리 실태를 조사하여 그에 따른 인식도와 수행도를 알아보고자 하였다. P지역에 소재한 종합병원급 이상 10개 병원의 혈관조영검사실에 근무하는 종사자 126명을 대상으로 2022년 1월 3일부터 1월 28일까지 설문조사를 실시하였으며 내용으로는 대상자의 일반적 특성 10문항과 혈관조영검사실의 감염관리의 주요 항목인 4개 영역 즉, 의료기관 내 감염관리체계, 개인위생, 혈관조영검사실 환경, 혈관조영검사실 장비로 구분한 총 56문항을 Likert 5점 척도로 측정하였다. 자료 분석은 SPSS for WindowTM release 25.0을 이용하여 통계 처리를 하였다. 일반적 특성에 따른 각 영역의 인식도와 수행도의 분석은 t-test, one-way ANOVA로 하였고 변수들 간의 관계는 Pearson 상관관계분석을 시행하였다. 결과로는 모든 영역에서 인식도가 수행도보다 높게 나타나 인식의 수준에 비하여 수행력이 낮음을 알 수 있었다. 또한 인식도와 수행도가 양의 상관관계를 보이고 있어 종사자의 인식 정도가 수행력에 유의한 영향을 미치는 감염관리의 중요한 변수임을 알 수 있었다. 따라서 효과적이고 체계적인 감염관리를 위해서 혈관조영검사실의 종사자는 감염관리의 수행도를 반드시 높여야 할 것이며 그러기 위해선 감염관리 교육이 필요할 것으로 생각되며 앞으로 혈관조영검사실 감염관리 지침이 체계화되어야 할 것으로 판단된다.

Purpose: This study was to evaluate the effects of information on anxiety, blood pressure and pulse in cerebral angiography clients. Methods: The data were collected from June to November 2014. The participants were 42 (21 each for experimental and control group) patients who to received cerebral angiography. The information developed from researchers' materials for cerebral angiography was provided only to experimental group. Measured variables were anxiety, systolic and diastolic blood pressure, and pulse rate. Research tools for anxiety were Spielberger's state anxiety inventory, and 10 point visual analogue scale (VAS). Results: The difference in mean systolic blood pressure after intervention between the experimental group ($129{\pm}15.34$) and the control group ($141{\pm}17.70$) was statistically significant (t=-2.28, p=.028). The differences between the two groups in state anxiety, VAS anxiety, diastolic blood pressure, and pulse rate after intervention were not statistically significant (p>.05). Conclusion: The information using educational material was effective in to decreasing systolic blood pressure in patients who received cerebral angiography. Therefore this study material could be used as a nursing intervention for patients in cerebral angiography.

Fistulas between the arteries and the gastrointestinal tract are rare but can be fatal. We present a case of an ilioenteric fistula between the left external iliac artery and sigmoid colon caused by radiotherapy for cervical cancer, which was treated with endovascular management using a stent graft. A 38-year-old woman underwent concurrent chemoradiotherapy for cervical cancer recurrence. Approximately 9 months later, the patient suddenly developed hematochezia. On her first visit to the emergency room of our hospital, computed tomography (CT) images did not reveal extravasation of contrast media. However, 8 hours later, she revisited the emergency room because of massive hematochezia with a blood pressure of 40/20 mmHg and a heart rate of 150 beats per minute. At that time, CT images showed the presence of contrast media in almost the entire colon. The patient was referred to the angiography room at our hospital for emergency angiography. Inferior mesenteric arteriography did not reveal any source of bleeding. Pelvic arteriography showed contrast media extravasation from the left external iliac artery to the sigmoid colon; this was diagnosed as an ilioenteric fistula and treated with a stent graft. When the bleeding focus is not detected on visceral angiography despite massive arterial bleeding, pelvic arteriography is recommended, especially in patients with a history of pelvic surgery or radiotherapy.

We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

In Raynaud's phenomenon, the authors measured finger blood flow after ice water exposure by analyzing the time activity curve of radionuclide angiography on both hands. The results were as follows: 1) The digital blood flow did not decrease after ice water exposure in normal subjects. 2) In the patients with Raynaud's phenomenon, there were two groups: the one had decreased digital blood flow after cold exposure, and the other had paradoxically increased digital blood flow after cold exposure. 3) There was no difference in the digital blood flow of hand in room temperature between the normal and the patients with reduced digital blood flow after cold exposure, but the digital blood flow of the hand in room temperature was markedly reduced in the patients with paradoxically increased flow after cold exposure. 4) In the static image the difference was not significant in comparision with the dynamic study, because it represents pooling of the blood in the vein rather than flow. 5) After the treatment with nifedipine, the digital blood flow increased. In conclusion, the radionuclide angiography was useful in measuring the digital blood flow in Raynaud's phenomenon, and further studies with various drugs is expected.

Objective : In the cerebral aneurysm surgery, the goal is complete circulatory exclusion of the aneurysm without compromise of normal vessels. In an operating room, an operator should confirm the completeness and precision of the surgical result, before closing the wound. Object of this study was to determine which cases require intraoperative angiography. Methods : We reported our experience with 48 intraoperative angiographic studies performed during the surgical treatment of cerebral aneurysm of these 48 cases. There were 5 giant(10.4%), 15 globular(1.5-2.5cm)(31.25%) and 28 saccular(58.3%) aneurysm. We recorded the incidence of unexpected findings, such as residual aneurysms, major vessel occlusions. Using Fischer's exact test, we assessed whether unexpected angiographic findings showed any correlation with aneurysm site, size and clinical findings. Results : In 5 cases(10.4%), we detected unexpected angiographic findings which resulted in clip adjustment. By means of clip adjustment, an operator could restore the flow of two major arterial occlusion(4.2%) and also obliterate three persistent filling aneurysms(6.3%). Globular aneurysm was the only factor to predict unexpected angiographic findings(p<0.05). The subgroup of globular and giant aneurysm has a high risk of occlusion of the parent artery and its branches and/or residual aneurysm. There were two minor complications related to this procedure. Conclusion : Intraoperative assessment makes it possible to recognize and correct the technical defect. Particularly in globular aneurysm, we were able to prevent both the chance for another operation and the risk of postoperative complications.

병원에서 사용하는 X선 장비는 X선 장비의 능력 연구와 더불어 출력되는 영상의 화질까지도 분석하는 연구가 활발히 진행되어야 한다. 영상의학과 장비의 X-Ray기계나 CT, MRI와 같은 장비의 후향적 이미지 분석은 활발히 진행되었으나 혈관조영실의 혈관조영장비를 이용하여 획득한 영상의 화질 측정은 팬텀을 이용하여 측정하는 방법이 대부분이고 실제 환자에게 촬영된 후의 영상에 관한 화질 측정은 미비한 실정이며 정확한 화질 측정 방법에 관한 연구가 현저히 부족한 상태이다. 따라서 본 연구를 통해 관상동맥 조영술 후 획득된 영상의 화질측정 방법을 고안한 연구를 진행해 시술자에게 질 높은 영상을 제공하고자 연구를 진행하게 되었다. 사용된 장비 및 프로그램은 혈관 조영 검사 장비(Axiom Artis Zee Ceiling)와 Image J프로그램을 사용하였다. 대상으로는 관상동맥 조영술 후 PACS프로그램에 자동 저장된 영상들을 대상으로 하였다. 화질 측정 방법으로는 Image J프로그램을 이용했을 때 관상동맥 조영술 중 좌 관상동맥의 주요 혈관들이 가장 잘 펼쳐져 보이는 각도의 영상인 AP Caudal 30°영상과 우 관상동맥의 혈관이 가장 잘 펼쳐져 보이는 LAO 30° 영상을 선택하여 선택된 영상의 배경영역(Background)과 관심영역(ROI)을 측정하기 위해 혈관과 간, 폐 등의 음영 중복이 가장 최소화 되는 구간을 찾아 측정하는 방법에 관한 기준을 제시하였다. 결론적으로 혈관 조영 영상의 화질측정 분석 방법은 정확히 제시되어 있는 기준이 없기 때문에 시술자에게 질 좋은 영상을 제공하기 위해선 그 장비의 기술자들뿐 아니라 실제로 사용하는 사용자들이 연구자가 되어 다양한 방법으로 화질측정에 관한 연구를 진행해야만 환자에게도 우수한 영상을 제공할 수 있을 것으로 사료된다.
