A congenital fistulous communication between the coronary artery and the cardiac chamber or the pulmonary artery is a rare condition, but increasing cases with this anomaly are being recognized with wide spread use of cardiac catheterization and coronary arteriography. Recently we experienced one case of right coronary artery fistula which was associated with atrial septal defect. The patient was a 24 year old female who was admitted because of cardiac murmur, palpitation and dyspnea on exertion after pregnancy. Cardiac catheterization and selective coronary arteriography revealed that a fistulous communication, forming a large aneurysm, was noted from the right coronary artery emptied into the right ventricle. On the operation field, the right coronary artery was curved and markedly dilated from the aorta to the middle segment at acute margin of the right ventricle. The egg-sized aneurysm of dilated right coronary artery was noticed on right ventricle. The aneurysm was incised longitudinally and both the proximal opening and the termination site of the fistula were closed directly with aneurysmectomy. The right atrium was also opened to evaluate the fistulous termination site and repaired only small interatrial septal defect. Postoperative course was uneventful and she was discharged without problems

We report a case of pseudoaneurysm formation after aneurysmal clipping. An aneurysm, which was located on the beginning of orbitofrontal artery, was clipped and wrapped with $Surgicel^{(R)}$ and fibrin glue. Four weeks later, an enlarged aneurysm was detected at the same site on postoperative angiography. We could not find a new aneurysm in the second operation except inflated wrapping region. And clip had been slipped from the original aneurysmal neck. So we concluded that a new aneurysm was a pseudoaneurysm made with surgicel and fibrin glue. And it had been formed from continuous minor leakage caused by slipped clip.

A rupture of a dissecting aneurysm of the aorta is life threatening disease and calls for emergency surgical treatment. The author recently experienced one case of ruptured dissecting aneurysm of the descending thoracic aorta complicated with left hemothorax who was recovered after emergency operation of Aug. 11, 1976. The patient was a 43 years old farmer with known hypertension [260/120] for 20 years but without any venereal disease and had experienced sudden throbbing chest pain. Chest film and aortogram revealed this case ruptured aneurysm of descending thoracic aorta complicated with left hemothorax. In this case, large dissecting aneurysm extend from proximal part of left subclavian artery below diaphragm and involved with 3.0 and 4.0cm sized elliptical rupture in proximal part of descending thoracic aorta. And so, neither fenestration procedure nor replacement of dacron artificial vessel was suitable for this case. Finally, only the rupture site of aneurysm was treated by covering with fibrous pleura and teflon patch. The post-operative management of this case was planned to control hypertension with antihypertensive drugs. The follow-up was possible up to date about 2months. The patient has been doing well with ordinary activities except mild chest discomfort.

A very rare case of mycotic aneurysm in the descending thoracic aorta due to salmonellosis was treated in our hospital The patient was a 62 year-old male who 48 days before the operation was admitted to the depart,cent of internal medicine complaining of fever. nausla. vomiting, and loose stool. He was treated for 35 days and discharged. Three days after discharge, however, the patient was readmitted to the hospital comE긴ainin프 of $\ulcorner$i포ht uppe$\ulcorner$ 킥uadrant abdominal pain. Fever developed on the third hospiti린 day, and on the eighth hospital day, the patient complAined of back pain and epigastric pale. A simple chest x-ray showed evidence of hemothorax in the left plueral space, and therefore, computed tomography of the chest was done. The patient was diagnosed as a ruptured mycotic aneurysm of the descending thoracic aorta, and was transferred to our Department of Thoracic and CArdiovascular Surgery. The aneurysm and infected tissues was widely debrided, and the site was then patched with a Dacron graft. Salmonella choleraesuis was identified in the blood and aneurysm cultures, and antibiotics were administered for weeks according to the sensitivity of the organism. The patient experienced no complication thereafter and for the last three months since the operation, he has been leading a healthy and normal social life.

Development of an aneurysm in the thoracic aorta, intercostal arteries, or cerebral vessels is not an uncommon occurrence in patients with coarctation of the aorta. The mechanism whereby coarctation predisposes to aneurysm formation is incompletely understood and we suggest that in this case, an intrinsic factor in the wall of the aorta underlies the formation of aneurysms. Recently we experienced one case of COA associated with the thoracic aortic aneurysm and operation was done successfully. PDA was simply ligated and the aorta was cross-clamped proximally and distally and the area of constriction or aneurysmal site were excised. Postoperative course was uneventful and the patient was discharged 2 weeks after operation. Hypertension at upper extremities was controlled without any antihypertensive drugs after operation and the degree of regurgitation of mitral valve was improved postoperatively but long-term follow-up should be necessary.

Simultaneous subarachnoid hemorrhage and infarction is a quite rare presentation in a patient with a spontaneous dissecting aneurysm of the anterior cerebral artery. Identifying relevant radiographic features and serial angiographic surveillance as well as mode of clinical manifestation, either hemorrhage or infarction, could sufficiently determine appropriate treatment. Enlargement of ruptured aneurysm and progressing arterial stenosis around the aneurysm indicates impending risk of subsequent stroke. In this setting, prompt treatment with stent-assisted endovascular embolization can be a reliable alternative to direct surgery. When multiple arterial dissections are coexistent, management strategy often became complicated. However, satisfactory clinical results can be obtained by acknowledging responsible arterial site with careful radiographic inspection and antiplatelet medication.

Aneurysms arising from the ophthalmic artery itself are very rare compared with aneurysms originating from the bifurcation of the ophthalmic artery and carotid artery. There was only one reported case of a ruptured aneurysm of the ophthalmic artery itself. We discuss clinical significance of an aneurysm at this site, as well as the role of three dimentional image of multislice computed tomography angiogram[3D-image of MCTA] in determining the cause of subarachnoid hemorrhage[SAH].

Dissecting aneurysm has long been recognized as an ominous and highly lethal form of aortic disease. Aortic dissection are characterized by longitudinal separation of aortic media and extension proximally, distally or both from the site of intimal tear. DeBakey and associates defined three types based on where the process originates and how far extends. In type I, intimal tear is located in the ascending aorta and extend beyond the descending aorta. We experienced a case of dissecting aneurysm, Type I of DeBakey`s classification which dissection extend to the left iliac artery. The patient was 61 years old woman and suffered from excruciating pain on admission. Excision of aneurysm and ascending aorta reconstruction using to Dacron Vascular Prosthesis were performed under extracorporeal circulation. The post-operative course was uneventful and follow up is continued.

Ehlers-Danlos syndrome (EDS) type IV is characterized by its clinical manifestations, which are easy bruising, thin skin with visible veins, and rupture of arteries, uterus, or intestines. Arterial complications are the leading cause of death in vascular EDS because they are unpredictable and surgical repair is difficult due to tissue fragility. The authors report a case presented with cervical radiculopathy due to a segmental fusiform aneurysm of the cervical vertebral artery. Transfemoral cerebral angiography (TFCA) was done to verify the aneurysmal dilatation. However, during TFCA, bleeding at the puncture site was not controlled, skin and underlying muscle was disrupted and profound bleeding occurred during manual compression after femoral catheter removal. Accordingly, surgical repair of the injured femoral artery was performed. At this time it was possible to diagnose it as an EDS with fusiform aneurysm on cervical vertebral artery. Particularly, cervical fusiform aneurysm is rare condition, and therefore, connective tissue disorder must be considered in such cases. If connective tissue disorder is suspected, the authors suggest that a noninvasive imaging modality, such as, high quality computed tomography angiography, be used to evaluate the vascular lesion to avoid potential arterial complications.

Objectives : The mortality rate of subarachnoid hemorrhage(SAH) has been reduced recently due to refinement of microsurgical technique and improved perioperative management. Also, many survivors of SAH show excellent neurological recoveries. However, we found that a high proportion of the survivors do not fully regain their premorbid status in cognitive and memory function. Object of this study is to evaluate which factors might influence on cognitive and memory impairment in ruptured aneurysmal SAH patients. Methods : In this prospective study, a series of 66 patients with aneurysmal subarachnoid hemorrhage(SAH) from 1996 to 1998, most of whom had a "good" or "fair" neurological outcome, were assessed with various tests of cognition and memory function. All patients underwent clipping operation by pterional approach. Right side approach was performed in 16 case and left 21 cases. K-WAIS(Korean-Wechsler Adult Intelligence Scale) was used as method of cognition and memory function test. The time interval between SAH and assessment varied between 4 months and 8 months, averaging 6.2 months. Statistical analyses were carried out for each test score to see whether aneurysm site(A-com : non A-com), route of approach, age and sex, vasospasm, Hunt-Hess grade and Fisher CT group at admission, Glasgow Outcome Scale(GOS) at discharge affect cognitive and memory function. Results : Aneurysm site was not shown to be associated with performance on any test, and the initial grade (Hunt-Hess grade, Fisher CT group) of SAH and vasospasm had only minimal predictive values. The grade at discharge( GOS) was proved to be the best predictor of impairment of cognition and memory function within 1 year after operation. Conclusion : The authors conclude that the diffuse effects of SAH are more important than focal neuropathology in relation to cognitive impairment in this group of patients.
