We report the case of a 64-year-old man with dural arteriovenous fistula (DAVF) at right jugular foramen, presented as subarachnoid and intraventricular hemorrhage. The malformation was fed by only the neuromeningeal trunk of the right ascending pharyngeal artery and drained into the right lateral medullary veins craniopetally. Complete embolization was attained by selective transarterial glue injection, but patient showed lower cranial neuropathies. A 3-month follow-up angiogram still showed persistent fistula occlusion. Transarterial glue embolization is a feasible method, only if a transvenous access is not possible in case of single channel fistula.

A 8 year old male was admitted to the Department of Thoracic Surgery, Korea University Hospital on June 22, 1978. The chief complaints were cyanosis and exertional dyspnea since at birth. EKG shows BVH and dextrocardia, phonocardiogram revealed the accentuation of second heart sound in aortic area. Echocardiogram from the left ventricle to the base of the heart, there is a discontinuity between the ventricular septum and the anterior aortic margin with a large aortic root & aortic overriding. His cardiac catheterization data and cardiac angiogram shows situs inversus totalis, dextrocardia, right aortic arch, large ventricular septal defect etc., and finally diagnosed Truncus Arteriosus. Edwards type IV with retrograde aortogram and selective bronchial angiogram. This is the first operative case reported as Rastelli operation for Truncus Arteriosus type IV in the literatures in Korea. Authors have experienced I case of Truncus Arteriosus, Edward type IV and Rastelli operation with Dacron Arterial Conduit Graft under cardiopulmonary bypass on July 3, 1978. The procedures were as follows; 2] Cardiopulmonary bypass: Origin of bronchial arteries excised from descending aorta bilaterally; defects in aorta closed. 2] Horizontal incision made high in right ventricle. 2] Ventricular septal defect [Kirklin type I+II] closed with Teflon patch. 4] Bifurcated dacron arterial graft with pericardial monocusp sutured to the bilateral pulmonary arteries. [Diameter 9 mm: Length 7 cm]. 5] Proximal end of the conduit graft anastomosed to right ventricle. [Diameter 19 mm: Length 5 cm]..Total perfusion time was 220 min. The result of operation was poor due to anastomotic leakage and increased pulmonary vascular resistance resulting acute right heart failure. The patient was died on the operation table. Literatures were briefly reviewed.

Congenital coronary arteriovenous fistula is relatively uncommon and widespread use of echocardiogram and selective coronary angiogram are being recognized with increasing frequency. The right coronary artery is most commonly involved and the fistulous communication is most common to right ventricle. Surgical correction is strongly recommended to prevent the development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and pulmonary hypertension, as well as coronary aneurysm formation, with subsequent rupture or embolism. We report two cases of coronary arteriovenous fistula originated from right coronary artery terminated in the right ventricle. These 8 year-old female and 7 year-old male patients had surgical interventions using cardiopulmonary bypasses.

본 논문에서는 수술 중 촬영된 2D XA(X-ray Angiogram) 영상에 수술 전 촬영된 3D CTA (Computed Tomography Angiography) 영상 정보를 융합 가시화하기 위한 고속의 강체 정합 기법을 제안한다. 본 논문에서는 두 혈관 사이의 특징점 정보를 이용하여 예측 투영 위치 지점을 추정하는 삼각 측정을 통한 추정치 예측 기법을 제안하여 빠르고 견고한 초기 정합이 가능하다. 이에 더하여 주축을 생성하여 정렬시킨 후 경계 상자를 이용하여 혈관의 형태를 비교하는 방법으로 더욱 정확한 초기 정합이 가능하다. 다음으로 정밀정합은 선택적 거리 측정을 통하여 각 영상에서의 혈관들의 거리 차이가 최소인 위치로 영상을 정합한다. 실험으로 5명의 환자 데이터에 대하여 영상정합을 하였고, 기존 기법과 수행 속도와 정확성, 견고성 측면에서 비교 평가하였다. 실험 결과 제안 기법은 기존 기법에 비하여 최적의 위치로 빠르고 견고하게 정합되었다.

기관지 동맥류는 드문 질환이나 파열되면 대량출혈이 일어나므로 응급으로 치료가 필요한 질환이다. 진단 즉시 수술적 치료가 원칙이나 최근 경도자 방법이 발전하여 기관지동맥색전술이 추천되고 있다. 반복적인 객혈로 내원한 환자에서 기관지확장증을 동반한 기관지동맥류를 진단하여 금속코일 색전술을 통해 치료에 성공한 1예를 보고하는 바이다.

3세 수컷 풍산견이 2주동안 지속된 좌측후지 파행과 식욕저하로 내원하였다. 환자의 외상 병력은 없었으며, 백신과 심장사상충 예방은 하지 않았다. 전혈구검사에서 중증의 백혈구 증가증과 호중구 핵좌방이동이 확인되었고, 혈액화학검사에서 저알부민혈증, 질소혈증, 간담도계 효소수치의 상승을 확인되었으며, 심장사상충 항원 키트에서 양성으로 확인되었다. 흉부 방사선 검사에서는 주폐동맥의 확장, 우심비대, 폐의 간질패턴이 관찰되었으며, 심장사상충 감염소견과 일치하였다. 이후 실시된 심초음파 검사에서 페동맥판역류와 폐성 고혈압이 확인되었다. 선택적 대퇴동맥 혈관 조영술에서 양측성 대퇴동맥의 폐쇄가 확인되었고, 환자는 혈관조영술후 폐사하였고 부검이 실시되었다. 부검결과 심장사상충 성충과 혈전이 좌우측 대퇴동맥 내강을 폐쇄시키고 있는 것이 확인되었다. 본 증례보고는 심장사상충이 대퇴동맥으로 비정상적 이주를 하여 후지의 파행을 유발한 케이스이며, 이를 보고하고자 한다.

A bronchial artery aneurysm is a rare condition, which needs optimal treatment due to the possibility of a life-threatening hemorrhage by rupture. The surgical removal of the aneurysm is the standard treatment. However, there are a few reports of coil embolization with a transcatheter. A 69 year-old man was referred for a further evaluation of a mass in the right hilum on chest radiography. He denied any respiratory symptoms. A chest CT scan showed a $3{\times}3{\times}4.5cm$ sized vascular mass with strong contrast enhancement on the right hilar area that originated from the bronchial artery. On the angiogram, the bronchial artery originated from the descending thoracic aorta at the T8 level. A bronchial artery aneurysm was catheterized selectively. and embolized successfully with a coil. After coil embolization, the selective bronchial arteriography confirmed complete occlusion. We report this case of bronchial aneurysm that was treated successfully with coil embolization.

Purpose : To observe the patency of anastomosis site and the findings of circulation of grafted fibula in osteonecrosis of femoral head treated with vascularized fibular graft by use of digital subtraction angiography. Materials and Methods : 17 cases of 11 patients who underwent vascularized fibula graft for osteonecrosis of femoral head. We performed digital subtraction angiography(DSA) for them at second week postoperatively in 12 cases, at sixth week in 1 case, at sixth month in 2 cases, at twelfth month in 1 case, and eighteenth month in 1 case which had been got DSA at second week before. We observe the patency of pedicle, and the circulation of grafted fibula such as periosteal and intraosseous vessels with time. Results : All cases except one which were thought failure of selective angiogram showed good passage of blood flow through anstomosed pedicle on DSA. We found the differences in appearance of circulation of grafted fibula with time. DSA at 2nd and 6th week postoperatively revealed both of periosteal and intraosseous vessels along the fibula and blood pooling at the tip of fibula. DSA at 6th month showed maintenance of periosteal and intraosseous vessels along the fibula but did not clearly reveal blood pooling at the tip of fibula. The findings of DSA at 12th and 18th month were similar each other. The periosteal vessels were not seen as the grafted fibular bone were incorporated into surrounding femoral bone but intraosseous vessels were still seen. Conclusion : It was thought that DSA could be used for evaluation of the status of pedicle including anastomsed site and vessels of grafted fibula with time. The periosteal vessels of fibula were decreased with time but intraosseous vessels were still seen until 18th month after vascularized fibula graft.
