We operated on a Marfan patient who had Stanford type A acute aortic dissection, aortic root aneurysm, and aortic regurgitation. The Yacoub-David aortic root remodeling procedure which preserves native aortic valve and replaces all three aortic sinuses and ascending aorta by a Dacron graft, was applied for this patient. A 24mm Hemashield graft was designed to three tongues at the aortic root end to meet the shape of the Valsalva sinuses. The patient recovered from the procedure uneventfully and there was no aortic regurgitation posto-peratively.

The localized form of subaortic stenosis shows a spectrum of pathological lesions varing from dis- crete membrane to a thickened flbromuscular collar. Aortic valve is commonly involved late in the pro- cess resulting in regurgitation. Because of the likelihood o the progressive obstruction and aortic regurgitation, early elective oper- ation should be considered for the patient with subaortic stenosis. We experienced a case of localized fibromuscular subaortic stenosis associated with aortic regurgi- tation. Excision of the fibromuscular ridge and septal myectomy-myotomy relieved the subaortic seen- osis. Regurgitant aortic valve was repaired by peeling away the Hbrotic tissue on the cusps and subcommissural annuloplasty at the each commissural area. On postoperative echocardiographic examination, the systolic pressure gradient between left ventricle and aorta decreased markedly and the aortic regurgitation was not detected at all.

배경 및 목적: Stand A형 급성대동맥박리증의 박리 시발점이 수술치환부위 내에 있는 경우와 그렇지 않은 경우의 임상적 차이점을 분석하여 치료에 도움을 주고자 하였다. 방법: 1991년 3월부터 1999년 7월까지 본원에서 급성상행대동맥박리증으로 진단되어 상행대동맥치환술을 받은 40명의 환자를 대상으로 병력기록을 근거로 수술 소견 상 찢어진 부위를 발견한 환자 27명을 1군, 발견 못한 나머지 13명을 2군으로 나누고 환자의 술 전 상태와 수술소견 및 술후 경과의 임상적 차이점을 분석하였다. 결과: 1군에서 술전에 저혈압, 대동맥판막부전, 심허혈, 신부전 등이 더 많이 발생되었다. 수술 소견 상 대동맥근부 이상은 1군에서 많았다. 가성 내강 내 혈종은 2군에서 더 많이 관찰되었지만 통계적으로 유의하지는 않았다. 술후에 2군에서는 신부전이 더 많이 발생하였고 술후 출혈로 인한 재수술은 1군에서 더 많았다. 조기 수술사망은 1군에 6명으로 사망률은 22.2%이었고 2군에는 사망 례는 없었다. 결론: 본 연구를 통하여 상행대동맥에서 내막 파열이 발견된 1군에서는 2군에 비해 술전 상태가 불량하였고 대동맥판막 병변으로 수술이 복잡해져 사망률이 높다고 생각된다. 반면 원위부 하행대동맥에서 박리가 진행되어 상행대동맥으로 이어진 2군에서는 1군에 비해 순환 장애로 인해 술후에 신부전이 더 많이 발생되었다. 결론적으로 상행대동맥내막에 파열점이 없었던 군에서 수술 예후는 상행대동맥내막에 파열점이 있는 군보다 더 좋았다.

Some extensive thoracic aortic aneurysms are not amenable to staged repair, such as extremely large distal aortic aneurysms that are unsuitable for an elephant trunk anastomosis, or aneurysms that are accompanied by complications such as ruptured descending thoracic aneurysm. We report here a case of successful replacement of the aorta from the ascending to the descending aorta in one operation. The patient was 65-year-old man who had an aneurysm which involved the entire thoracic aorta and ruptured in the descending aorta. The operation was performed via transverse thoracosternotomy, and under the deep hypothermic circulatory arrest with retrograde cerebral perfusion. The patient recovered uneventfully and was discharged without any neurologic complications.

A 28 years old pregnant woman(Gestational age 35 weeks) had been operated emergency Cesarian section for delivery and emergency graft replacement of ascending aorta and total arch for acute type A aortic dissection. 1 year and 6 months later, she underwent aortic graft replacement from descending thoracic aorta to both common iliac arteries because of further progression of aortic dissection. So far she has a complete artificial graft aorta.

The treatment modalities of the intramural hematoma (IMH) remain controversial. Nowadays, the IMH of the descending thoracic aorta is generally classified in the medical treatment category. We describe a patient with IMH of the descending thoracic aorta who received the medical treatment. During the follow-up, we speculated that the IMH had been aggravated leading to an aortic rupture including hemothorax. Therefore, we performed an emergency operation. Contrary to our expectations, operative findings showed a well-organized aortic wall and serous pleural effusion. The exact diagnosis was IMH of the descending thoracic aorta with penetrating atherosclerotic ulcer (PAU). This case reminded us of the importance of accurate diagnosis and proper treatment.

In patient with severe adhesion between lung and aorta, there is some limitation in approaching the distal arch or descending thoracic aorta through the usual left thoracotomy. We report a case of a successfully managed distal arch and descending thoracic aortic aneurysm through the median sternotomy without any manipulations of the lung in a 66 year old man who presented hemoptysis.

A case of distal aortopulmonary septal defect associated with aortic origin of right pulmonary ar- tery, patent ductus arteriosus and hypoplasia of aortic isthmus in a 50-day-old female infant is presented. Ligation of patent ductus arteriosus, resection and end-to-end anastomosis of hypoplasia of aortic isthmus, implantation of rlght pulmonary artery to main pulmonary artery and autologous peri- cardial patch repair of aortopulmonary septal defect were performed under cardiopulmonary bypass as one-stage approach. Deep hypothermic total circulatory arrest was applied during repair of hypoplasia of aortic isthmus. The p stoperative course was uneventful.

This is a genuine case report of the Ross operation without the use of homografts or heterografts in reconstruction of the right ventricular outflow tract. A 8-year-old boy with congenital aortic stenosis underwent aortic valve replacement with a pulmonary autograft and right ventricular outflow tract reconstruction with a pericardial conduit bearing autologous aortic monocusp. The postoperative echocardiography and cardiac angiography revealed good ventricular function and competent neoaortic valve. He has been followed up for 19 months.
