Due to the increased use of percutaneous diagnostic and therapeutic procedures, clinicians are now faced with a greater number of iatrogenic arterial injuries. The pattern of injury is changing as more complex procedures are being performed in patients with diffuse advanced atherosclerosis. If not recognized and treated appropriately, iatrogenic arterial injuries may threaten life and limb. A predilection for the iliofemoral segment as the site of injury exists because of the relative accessibility and, therefore, frequent use of the the femoral artery as well as its common involvement by atherosclerotic disease. Arterial injuries may present with hematoma, pseudoaneurysm formation, excessive bleeding, acute ischemia, or arteriovenous fistula. We experienced a case of pseudoaneurysm of the femoral artery and expanding retroperitoneal hematoma after transfemoral angiography was performed in patient with diffuse advanced atherosclerotic lesion and treated with artificial graft between external iliac and superficial femoral artery.

폐동정맥기형은 만약 치료하지 않으면 실질적인 위험성을 가지고 있다. 문헌에 의하 면 40-50%에서 비가역적인 색전을 보고하고 있다. 경피적경관색전술은 폐동정맥기형의 치 료에 보편적인 방법이다. 저자들은 분리형풍선을 이용하여 폐동정맥기형을 경피적경관색전 술로 성공적으로 치료한 1예를 단기적 소견및 전산화단층 촬영을 이용한 장기 추적 결과를 보고하고자 한다. Pulmonary arteriovenous malformation(PAVM) are associated with substantial risks if left untreated. The literature reports a 40-50% incidence of paradoxical embolization. Percutaneous arterial embolization has become the standard treatemtn for PAVM. We report a case of pulmonary arteriovenous malformation successfully treated by transcatheter embolization using detachable balloons and we also demonstrate long-term follow up CT findings.

위십이지장동맥류는 비교적 희귀한 질환이며 만성췌장염에서 췌장 효소의 자가소화 로 인하여 발생하는 생명을 위협하는 합병증이다. 경피적경관색전술은 가성동맥류의 치료에 우선적으로 선택하는 치료방법이다. 수술적인 치료방법은 높은 이환율과 사망률을 가지고 있다. 저자들은 만성췌장염을 가진 30세 남자 환자에서 추적 복부 전산화단층촬영상 위십이 지장동맥에 발생한 가성동맥류을 코일을 이용한 경피적경관색전술로 성공적으로 치료한 1예 를 보고하고자 한다. Gastroduodenal artery pseudoaneurysm is a relatively rare and potentionally life-threatening complication of chronic pancreatitis, which is thought to occur because of autodigestion of arterial walls by pancreatic enzymes. Embolotherapy should probably be the first method of treatment, since surgical treatment carries a high risk of mortality and morbidity. We report the case of 30-year-old male with gastroduodenal artery pseudoaneurysm caused by chronic pancreatitis which was successfully treated by transcatheter embolization using Gianturco spring coils.

This research suggests the development of simulator for a Simulation Test of a moving object’s path generation and following. There are many kinds of moving objects in weapon systems, such as vehicles, missiles, robots and so on. So need tests of moving simulations during development process of weapon systems. To simulate a moving object, need an flexible path. So this report suggests a Bézier curve algorithm for generation of smooth curve path. And when new developments of weapon systems are started, many kinds of simulators are created. But, these simulators are not reused in other project because there are different kinds of development environment. So need to allow users to add specific features, And this report suggests using Dynamic Link Library(DLL)
