We have experienced two cases of ascending aorta aneurysm with aortic regurgitation in Marfan`s syndrome. There were abnormal findings in cardiovascular system associated with abnormalities of skeletal systems. They had total replacement of the ascending aorta and aortic valve with Bjork-Shiley`s aortic valve composite graft and reimplantation of coronary ostia on the graft. Their postoperative courses were uneventful and discharged with good clinical results for follow up.

Aortic dissection, a condition characterized by hemorrhage into the media and variable extension along the length of the aorta, has long been recognized as a catastrophic Cardiovascular event. Recent developments in diagnostic and therapeutic skills have improved the prognosis considerably, but there is still controversy as to how cases should be managed. We experienced a case of dissecting aortic aneurysm [DeBakey Type III ], which were managed using intensive medical treatment. The period of follow up was about 11 years. At last, patient was died by progression of dissection into proximal aorta and resulted in aortic insufficiency and congestive heart failure.

The use of the patient`s pulmonary valve for replacement of the patient`s diseased aortic valve was introduced and developed by Mr. Donald Ross. The long term benefits of having a normal, fully viable, trileaflet semilunar valve in aortic position was demonstrated. A 38 year old male had histories of failures of previously implanted aortic prosthetic valves twice and evidence of progressive heart failure. At operation, aortic root abscess was found; the abscess extension to adjacent structures and partial valve dehiscence had occurred. The patient underwent replacement of the aortic root with autologous pulmonary valve, autologous pericardial patch repair of left ventricuar outflow tract and recontruction of the right ventricular outflow tract and pulmonary artery with prosthetic valved conduit. Postoperatively, the patient recovered well. Postoperative doppler echocardiography demonstrated minimal central regurgitation in new aortic valve. Aortic root replacement with pulmonary autograft in a patient of recurrent aortic root abscess and false aneurysm of left ventricuar outflow tract was experienced and reported with follow up echocardiography.

복부 대동맥류는 수술적 치료가 일반적으로 행해져 왔으나, 최근 스텐트 그라프트가 새로운 치료법으로 소개되고 있다. 본 병원에서 고혈압, 뇌졸중으로 및 신기능의 저하 등으로 거동이 불가능한 고위험 군의 복부대동맥류 환자에서, 흉부외과의사가 스탠트 그라프트를 시행한 경험을 하였기에 보고하는 바이다.

Dissecting aortic aneurysm is relatively rare in those under 40 years of age without high risk factors. After dessecting aortic aneurysm is occured, the coronary artery is rarely perfused by false lumen. We present a thirty two-year-old man who showed Debakey type 1 dissecting aortic aneurysm with right coronary artery perfused by false lumen of ascending aorta and with congestive heart failure due to aortic insufficiency without discernible risk factor. Medical and surgical treament(Modified Bentall's operation) were successfully performed. The pathologic report showed combined cystic medial necrosis. Now he is well tolerated and stable only with anticoagulation during follow up 18 months.

본 연구에서는 복부대동맥류가 발생한 환자들에서의 연령과 복부대동맥류 형상에 따른 벽 응력과 파열 위험성을 평가하였다. 복부대동맥류의 형상은 의료영상 데이터로부터 추출되어 모사되었으며, 재료 물성치 단계에서는 동맥 조직의 이방성 초탄성 성질을 모사하기 위해 Gasser-Ogden-Holzapfel 모델을 적용하였다. 또한, 모델에서 필요한 각 재료 정수들은 환자들의 연령과 정상 조직 및 동맥류 조직의 특성들을 고려하기 위하여 각기 다른 값들로 산정되었다. 게다가 복부대동맥류에서의 대동맥 직경과 목의 각도에 관한 상관관계를 분석하고, 이에 대한 시리즈 시뮬레이션 역시 수행되었다. 그 결과, 복부대동맥류 환자의 연령과 대동맥 직경, 그리고 대동맥 목의 각도에 따른 복부대동맥류의 파열 위험성이 평가되었다.

Twelve patients underwent surgical interventions for aortic aneurysms consecutively from September 1986 to September 1990 in the Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. They were all men ranging in age from 25 to 68 years with the mean age of 48 years. Five patients of them had aneurysms involving ascending aorta, one aneurysm involving both ascending and descending aorta, four aneurysms involving descending thoracic aorta, and the others had aneurysms involving abdominal aorta. According to morphological classification, six cases of them were in dissection and the others in fusiform aneurysms. All the cases were pathologically true aneurysms and four of them were in acute status. According to causal classification, seven patients of them had atherosclerosis, three cystic medial necrosis, and the others had syphilis and trauma respectively. Six patients with ascending aortic aneurysm had annuloaortic ectasia with aortic regurgitation and underwent ascending aortic graft and aortic valve replacement[Bentall`s operation]. The others with descending thoracic and abdominal aortic aneurysms underwent Dacron graft replacement. Both hemorrhage necessitating reopening of the chest and wound dehiscence were observed in three patients and hoarseness in one patient. Cerebrovascular accident occurred three and a quarter years postoperatively in one patient and he died two days later. The others were followed up via OPD and have been doing well postoperatively.

대동맥-대정맥 누공은 복부 대동맥류의 $1\%$ 이하에서 발생하는 희귀한 합병증 중 하나이다. 오랜 기간 동안 고혈압과 복부 대동맥류 병력을 가진 64세 남자 환자가 흉통, 호흡곤란, 상복부 불쾌감 그리고 박동성 복부 종괴를 주소로 내원하였다. 이학적 검사상 수축기 혈압이 70mmHg로 저혈압을 보였고, 복부에서는 박동성 종괴가 촉지되었고, 지속성 기계 잡음이 청진되었다. 검사실 소견으로는 혈색소(11.0 g/dL), BUN (5 mg/dL), creatine $(2.6\;mg\%)$이었고, 복부 전산화 혈관 촬영 결과, 10cm 크기의 신장하복부대동맥류와 복부 대동맥류와 대정맥을 연결하는 대동맥-대정맥 누공이 형성되어 확장된 대정맥 소견을 보여 응급 수술을 계획하였다. 대동맥류를 절개하고 혈전 제거 후, 1cm크기의 대동맥-대정맥 누공이 발견되었다. 대동맥-대정맥 누공은 도뇨관 풍선 확장술을 이용하여 지혈하였고, 대동맥류 밖에서 누공은 단순 지속 문합으로 봉합하였다. 대동맥-양측 장골동맥 이식편을 이용하여 대동맥류에 대한 수술을 마무리하였다. 환자는 수술 후 특별한 문제없이 퇴원하였다.

Aortoesophageal fistula is an uncommon and fatal complication after surgery of aortic aneurysm. A case of aortoesophageal fistula as a complication of synthetis patch aortoplasty for mycotic aneurysm of descending thoracic aorta is described. After 3 months since patch aortoplasty for mycotic aneurysm of descending thoracic aorta this patient visited the emergency room due to melena and hematemesis. After gastrofiberoscopy and computed tomography the patient was taken ot the operating room. The surgical intervention was performed in two steps. Median sternotomy and midline laparotomy were made. Hemashield's Dacron(16mm) bypass between ascending thoracic aorta and infra-renal abdominal aorta was established first. Through the posterolateral thoracotomy false aneurysm and previous Hemashield's Dacron patch of descending aorta were resected. The two ends of the aorta were sutured and esophageal fistula was repaired. The esophageal suture line and the stumps were covered with omental graft. Thirty months later the patient has had no difficulty referable to the aortic surgery.

Pseudocoarctation is extremely rare and is due to elongation and kinking of aortic arch which mimiks true coarctation but has no pressure gradient across it. This state is essentially benign entity and needs no surgical intervention, but it frequently tends to progress into the aortic aneurysm that results in compressive symptom due to mass effect and unawared rupture and death.We experienced a descending aortic aneurysm secondary to pseudocoarctation. The patient was 53 year-old female presented as easy f`atiguability and facial flushing. The aortogram revealed tortuous and enlarged aorta at the level of ligamentum arteriosum. The aneurysm was resected and was end-to-end anastomosed successfully under partial cardiopulmonary bypass. The postoperative course was uneventful and the patient was discharged on postoperative 10 day.
