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.

인제대학교 서울백병원에서 2례의 상간장막동맥에 발병한 감염성 동맥류를 경험하였다. 한 예는 세균성 심내막염에 병발한 감염성 색전증이 상간장막동맥에 발생하여 동맥류를 형성하였고 다른 예는 8개월 전에 발생한 살모넬라 장염에 합병한 일차적 동맥염이 원인이다. 이 동맥류들은 복부 초음파검시로 발견되었고 전산화단층촬영과 혈관조영술로 확진되 었으나 수술할 당시 2례에서 균배양은 되지 않았다. 두환자에서 장으로 순환되는 충분한 부행혈류가 있어 혈관재건 없이 동맥류를 절제만하여 성공적으로 수술하였다. 두환자에서 각각 일년과 9개월간 추적관찰중 동맥류의 재발은 없었다.

Purpose: Pulmonary cement embolization after vertebroplasty is a well-known complication. The reported incidence of pulmonary cement emboli after vertebroplasty ranges frome 2.1% to 26% with much of this variation resulting from which radiographic technique is used to detect embolization. Onset and severity of symptoms are variable. Case description: We present the case of a 83-year-old women who underwent fourth lumbar vertebroplasty and subsequently had dyspnea several days later. Posteroanterior chest radiography showed multiple linear densities. Computed tomography of thorax revealed also multiple bilateral, linear hyperdensities within the lobar pulmonary artery branches are detected in axial and coronal views. Literature Reviews: Operative management of vertebral compression fractures has included percutaneous vetebroplasty for the past 25 years. Symptoms of pulmonary cement embolism can occur during procedure, but more commonly begin days to weeks, even months, after vertebroplsty. Most cases of pulmonary cement emboli with cardiovascular and pulmonary complications are treated nonoperatively with anticoagulation. Endovascular removal of large cement emboli from the pulmonary arteries is not without risk and sometimes requires open surgery for complete removal of cement pieces. Conclusion: Pulmonary cement embolism is a potentially serious complication of vertebroplasty. If a patient has chest pain or respiratory difficulty after the procedure, chest radiography and possibly advanced chest imaging studies should be performed immediately.

A 53-year-old male patient who had suffered from acute myocardial infarction before a week was admitted due to postinfarction angina A mobile pedunculated left ventricular thrombus of 2.0-cm diameter which was overlooked in cardiac catheterization and ventriculographic study was diagnosed with transthoracic two-dimensional echocardiography. There was no exact clinical finding of left ventricular aneurysm and the thrombus was placed in the akinetic and hypokinetic apical portion. For preventing systemic embolism that was removed through a left ventriculotomy just prior to coronary artery bypass grafting.

Eighty-four cases of mitral commissurotomy were done in this department between October 1958 and September 1970. Therc wcre 54 males and 30 females. Six cases were under the age of 20 years. Prcoperativc embolization occurred in 9. 5% of the cases. consisting of 8. 3% cerebral and 1.2% peripheral embolization. Intraoperative and postoperative cmbolization occurred in 4.7% of the cases, with 1. 2% cerebral and 3.5% peripheral embolism. Two out of three postopeative embolism cases expired, one of which was caused by septic cerebral embolism due to valve vegetation nnd the other by mesenteric embolism. Atrial fibrillation was 1loted ill 43% of the case. Seventy closed mitral commissurotomy was done by left appendegeal approach with finger fracture method or Bailey's guillotine valvotome. Fourteen open mitral commissurotomy cases were done either by right side approach or median sternotomy, three of which were reoperation cases after blind mitral commissurotomy. One out of 14 cases were operated on with open mitral commissurotomy and concomitant open aortic valve bicuspidalization, This case expired due to severe serum hepatitis ten days after operation. Thirty-two per cent of valve calcification was noted during operation and one of which had marked vegetation on the valve cusps too. Operative mortality was 1.4% in blind mitral commissurotomy and 14% in open mitral commissurotomy. Over-all mortality in the entire series was 3.5%. One case among the blind commissurotomy cases expired during operation due to left inferior pulmonary vein laceration and death was caused in two open mitral commissurotomy cases by coronary artery airembolism. Three hospital death occurred in blind operation group, one due to coronary embolism, and two by hepatic failures. Three hospital death among open heart surgery cases were caused by hepatic failure in two and cerebral embolism in one cases. ln most of the survivors improved functional capacity and exercise lolerance were noted.

Between January 1986 and August 1993, 11 patients underwent surgical repair of ventricular septal defect [VSD] complicated with myocardial infarction. The ages of patients were ranged from 22 years to 83 years with a mean of 64 years. There were 8 male and 3 female patients. The preoperative cineangiograms of all patients were reviewed to measure both ventricular function and to evaluate coronary artery disease. The mean time interval between occurance of VSD and operation was 13 days. The operations were performed as soon as possible if there were hemodynamic derangement. Postmyocardial infarction VSD were repaired simultaneuously with coronary artery bypass graft in 3 patients, repaired with left ventricular aneurysmectomy in 6 patients, with left ventricular thrombectomy in 1 patient and with mitral valve chordae repair in 1 patient. There was no early death [within 30 days]. There were 6 postoperative complications; one with perioperative myocardial infarction, two with recurred VSD on postoperative 1 and 6 days respectively, two with lower leg embolism associated with intraaortic balloon pump insertion, one with wound infection. Of the complicated patients, 1 patient with lower leg embolism performed left above ankle amputation. Among two patients with recurred ventricular septal defect, one patient is doing well without problem. On follow up echocardiogram, the residual VSD was occluded completely. However another patient was with recurred VSD died 3 months after the operation because of congestive heart failure. Of the long term survivors, all patients are in NEW YORK Heart Association functional Class I or II. Although number of patients were small, our results of surgical closure of postmyocardial infarction VSD were favored to the others. Moreover, seven patients with preoperative cardiogenic shock among 11 were performed early operation after diagnosis of ventricular septal rupture. All of the patients were survived and doing well during the follow up period. Therefore early diagnosis with aggressive preoperative care with intraaortic balloon pumping and early operation seems to be very important for prevention of deterioration of vital organ.

To determine the magnetic resonance (MR) imaging findings and natural history of cerebral fat embolism in a cat model, and to correlate the MR imaging and histologic fmdings. Intemel carotid artery of 11 cats was injected with 0.1 ml of triolein. T2-weighted, T1-weighted and Gd-enhanced T1-weighted images were obtained serially for 2 hours, 1 days, 4 days, 1 week, 2 weeks and 3 weeks after embolization. Any abnormal signal intensity was evaluated. After MR imaging at 3 weeks, brain tissue was obtained for light microscopic (LM) examination using hematoxylin-eosin (HE) and Luxol fast blue staining, and for electron microscopic examination. The LM examination with HE staining revealed normal histological findings in the greater part of an embolized lesion. Cystic change was observed in the gray matter of 8 cats, while in the gray and white matter of 3 cats. At LM examination, Luxol fast blue, staining demonstrated demyelination around the cystic change occurring in the white matter, and EM examination of the embolized cortex revealed sporadic intracapillary fat vacuoles (n=11) and disruption of the blood-brain barrier (n=4). Most lesions were normal, however, and perivascular interstitial edema and cellular swelling were mild compared with the control side. The greater part of an embolized lesion showed reversible findings at MR and histological examination. Irreversible focal necrosis was, however, observed in gray and white matter at weeks 3.

인공심폐기를 사용하지 않는 관상동맥우회술에서 이식편의 근위부 문합을 상행대동맥에 시행하는 경우 상행대동맥의 조작으로 인한 공기나 대동맥조직, 죽종(atheroma) 등으로 인한 색전증과 대동맥 손상으로 유발되는 대동맥박리, 가성동맥류 등의 합병증을 유발할 수 있다 대동맥근부치환술 시 양측관상동맥의 재이식 시 도관을 사용하는 Cabrol 술식을 관상동맥우회술 시 적용하였다. 요골동맥이식편은 복재정맥과 다르게 혈관 내 판막이 없다는 이점을 고려하여 근위부 문합을 상행대동맥에 평행하게(side to side) 문합하여 하나의 근위부 문합으로 요골동맥이식편의 양측으로 혈류를 공급하는 Cabrol 술식을 이용하여 근위부 문합 수를 줄일 수 있으며 상행대동맥의 조작 수를 줄여 대동맥의 외상을 줄일 수 있다고 생각한다.
