True aneurysms of the coronary artery after aortic root replacement in Marfan syndrome patients are very rare. An anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva adds complexity during aortic root surgery. We present a case of a 37-year-old male patient with Marfan syndrome who had an RCA anomaly and a 4.5-cm true aneurysm of the common coronary button 14 years after a previous Bentall procedure. A redo Bentall operation and hemi-arch replacement were successfully performed. The anomalous origin of the RCA from the left sinus of Valsalva was safely divided and anastomosed as separate coronary buttons to the prosthetic composite valve graft. To prevent coronary button aneurysms after aortic root surgery in Marfan patients, the coronary buttons and the corresponding side holes on the prosthetic graft must be reduced to the maximum possible extent.

Purpose: Prognostic factors of coronary aneurysms in Kawasaki disease have been investigated in many studies. The aim of this study was to identify risk factors associated with early and late coronary artery outcomes in treated patients with Kawasaki disease. Methods: A total of 392 patients diagnosed with Kawasaki disease from January 2012 to December 2015 in Pusan National University Children's Hospital were retrospectively selected as subjects of the present study to determine risk factors for coronary aneurysms and persistence of coronary aneurysms after a 1-year follow-up. Results: Coronary aneurysms were detected in 30 of 392 patients within 1 month after the occurrence of Kawasaki disease. Coronary aneurysms persisted in 5 of 30 patients after a 1-year follow-up. A long duration of fever (adjusted odds ratio [OR], 1.47; 95% confidence interval [CI], 1.06-2.02; P=0.018) and high platelet count (adjusted OR, 1.00; 95% CI, 1.00-1.01; P=0.009) were found to be independent factors to predict the development of coronary aneurysms in the early phase. Initial coronary severity (adjusted OR, 46.0; 95% CI, 2.01-1047.80; P=0.016) and a high white blood cell count (adjusted OR, 1.17; 95% CI, 1.01-1.36; P=0.028) were found to be significant factors for the persistence of late coronary aneurysms in univariate analysis. However, no significant factors were found in multivariate analysis. Conclusion: These data are from early and late follow-up of coronary aneurysms in our unit. Further studies are needed to determine the mechanisms involved in the disappearance of coronary aneurysms and related factors.

관상동맥류는 비교적 드문 질환으로 내과적 또는 수술적 치료방법에 대해서는 논란이 있다. 관상동맥류의 원인으로는 동맥경화증, 가와사키병, 염증성 혈관질환, 결체조직질환 및 선천선 기형 등이 있다. 본원에서는 50세 남자환자가 관상동맥 조영술 시행 결과 다혈관 관상동맥류를 진단받고 관상동맥 우회로술을 시행하였기에 문헌고찰과 함께 보고하는 바이다.

Kawasaki disease (KD) is a systemic vasculitis in infants and young children. However, its natural history has not been fully elucidated because the first case was reported in the late 1960s and patients who have recovered are just now entering middle age. Nevertheless, much evidence has raised concerns regarding the subclinical vascular changes that occur in post-KD patients. KD research has focused on coronary artery aneurysms because they are directly associated with fatality. However, aneurysms have been reported in other extracardiac muscular arteries and their fate seems to resemble that of coronary artery aneurysms. Arterial strokes in KD cases are rarely reported. Asymptomatic ischemic lesions were observed in a prospective study of brain vascular lesions in KD patients with coronary artery aneurysms. The findings of a study of single-photon emission computed tomography suggested that asymptomatic cerebral vasculitis is more common than we believed. Some authors assumed that the need to consider the possibility of brain vascular lesions in severe cases of KD regardless of presence or absence of neurological symptoms. These findings suggest that KD is related with cerebrovascular lesions in children and young adults. Considering the fatal consequences of cerebral vascular involvement in KD patients, increased attention is required. Here we review our understanding of brain vascular involvement in KD.

Kawasaki s disease is a multisystemic disorder that is an important cause of cardiovascular disease in children. We experienced a case of coronary artery aneurysm secondary to Kawasaki s disease. The patient was 12-year-old female presented as exertional dyspnea & chest pain[NYHA classII . Her coronary angiogram showed saccular aneurysms at proximal right coronary artery and proximal left anterior descending artery. CABG was performed by use of double internal mammary artery.Postoperative E.K.G. showed a normal pattern.She discharged at postoperative 10th day without problem. 4 months after discharge, she had no dyspnea & chest pain in exertion[NYHA class I .

다발성 관상동맥류는 성인에서 매우 드물게 보고되고 있다. 그 발생 원인으로는 동맥경화, 선천성 혈관 기형, 외상, 매독과 관련된 혈관 병변, 결체조직 질환, 가와사키병 등이 있으며, 일반적으로 관상동맥의 혈관구조물 중에서 중피(media)의 약화와 관련이 있다. 현증이 있거나 파열, 색전, 종괴로 인한 압박에 기인한 부정맥, 허혈 등의 합병증을 예방하기 위해 수술적 치료를 고려할 수 있다. 저자들은 중간지와 좌 회선지 관상동맥의 기시부에 위치하는 다발성 관상동맥류와 관련하여 파열 및 부정맥이 동반된 환자에서의 수술적 치료에 대해 증례 보고를 하는 바이다.

Ascending aortic aneurysms are usually treated with graft replacement under cardiopulmonary bypass. However, if a candidate for off-pump coronary artery bypass grafting has an enlarged ascending aorta, surgeons may consider wrapping it without cardiopulmonary bypass. Here, we report a 78-year-old female who underwent successful wrapping of the ascending aorta concomitant with off-pump coronary artery bypass grafting, using a new wrapping technique that involves multiple bootstraps.

Giant coronary artery aneurysms are rare and challenging to treat because of variation in the presenting symptoms and the lack of established management guidelines. We report the case of a patient with a 6-cm-wide giant coronary artery aneurysm that was resected, followed by reconstruction using a saphenous vein graft and 18 years of follow-up.

목적: 국내 가와사키병 환아의 장기 예후에 대해 알아보고 장기 추적 관찰의 필요성에 대해 논의하고자하는 것이다. 방법: 가와사키병으로 입원한 354명에서 심초음파 검사와 운동부하검사에 동의한 환아 48명을 대상으로 하였다. 발병 후부터 재내원하여 추적검사를 받기까지 평균 11.6년(8.2-17.0년) 경과하였다. 발병 당시 관상동맥류가 없었던 환자군을 1군, 소동맥류가 있었던 환자군을 2군으로 구분하여 장기추적검사상 두 군의 차이와 이상소견여부를 분석하였다. 결과: 장기 추적목적의 초음파와 운동부하검사에서 대부분 이상 소견을 보이지 않았으나 2군에서 9세 남아 1명이 관상동맥 확장소견을 보였다. 운동부하검사는 두 군 모두 정상 소견을 보였고 심초음파 검사상 1군에서 100%, 2군에서 93.3%에서 이상이 없었다. 결론: 소동맥류가 있었던 환자군 중 일부에서 관상동맥 확장을 보였으므로 관상동맥 합병증이 발생한 환자에서 선택적으로 장기적인 추적검사가 필요할 것으로 보인다.
