Although outcomes of neonatal cardiac surgery have dramatically improved in the last two decades, low body weight still constitutes an important risk factor for morbidity and mortality. In particular, cardiac surgery in neonateswith very low birth weight (${\leq}$1.5 kg) is carried out with greater risk because most organ systems are immature. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,480 gram neonate.

A 2.5-kg neonate with coarctation of the aorta and a small left ventricle experienced a severe pulmonary hypertensive crisis. An emergency pulmonary artery-to-systemic artery shunt was placed to break the positive feedback loop caused by pulmonary hypertension and functional mitral stenosis. This shunt provided immediate relief of suprasystemic pulmonary hypertension and the resultant low cardiac output.

Coarctation of the aorta was rare condition among the congenital cardiovascular defects in Korea. We experienced a case of coarctatlon of the aorta [postductal type], which was successfully corrected by resection and end to end anastomosis. This patient, 21 years male patient, was admitted to the medical department for evaluation of hypertension, headache and exertional dyspnea during 4 years, and transferred to the department of chest surgery for operation. On physical examination, blood pressures were measured on both extremity, measuring 190/100mmHg on the arm and 100/80mmHg on the leg. Systolic murmur was heard on 2nd to 3rd left intercostal space and left sternal border. On simple chest x-ray, rib notching was seer/on low border of right 3rd and left 4th rib. Final preoperative diagnosis was made by the retrograde aortic catheterization and aortography, which showed the typical configuration of postductal type of coarctation with poststenotic dilatation of the aorta. On 20th, July, 1978, under the general anesthesia with endotracheal intubation, resection of coarctation of the aorta and end to end anastomosis was performed. During clamp for resection, blood pressure of upper extremity was elevated to 200/140mmHg, and controlled by Arfornad. During recovery, blood pressure over 160ramrig in systole was controlled by Reserpine for 8days postoperatively. At discharge, postoperative 8th day, brachial and femoral artery pressure was 145/85 mmHg and 135/80mmHg. After discharge, there was no evidence of specific symptoms and hypertension without antihypertensive drug.

Coarctation of aorta, a well known congenital cardiovascular defect, can be recognized in the most instances by simple finding of physical examination. This condition shortens life if untreated, but it can be corrected surgically to render the patient functionally normal. It seems relatively rare in Asian. During Six-Year period from January, 1982 through June, 1988, twenty four consecutive operations for the coarctation of the aorta were performed at Yonsei Medical Center. The patients included 14 males and 10 females in the range, 2 months and 34 years old. Associated Cardiac anomalies were patient ductus arteriosus, ventricular septal defect, mitral valve regurgitation, aortic stenosis, double outlet right ventricle, corrected transposition of great vessel, etc. The preoperative main symptoms were frequent URI and dyspnea. Congestive heart failure was the most common symptom at the group younger than 2 year olds. Operative techniques for the coarctation of the aorta were prosthetic patch aortoplasty in 18 patients, resection & vascular graft interposition in 4, resection and end to-end anastomosis in 2. There was no operative death. Four patients had persistent or paradoxical hypertension, and one had postoperative paraplegia.

Takayasu’s disease produces the occlusive and aneurysmal lesions of major branches of the aorta. Angiography is the most important diagnostic procedure in Takayasu’s disease. Surgical treatment is often justified to avoid the possible lethal consequences of hypertension on the heart, kidney, and brain, as well as in the case of aneurysm because of its risk of rupture. We experienced one case of the Takayasu’s disease associated with abdominal coarctation and renovascular hypertension. The patient was 17 years old female and had suffered from hypertension for 14 months. On physical examination, BP was 150/100 mmHg in the right arm and 120/80 mmHg in the left arm. The pulses of the left brachial and femoral arteries were weakly palpable. Aortogram showed the stenosis of the left common and subclavian arteries, coarctation of the abdominal aorta, and stenosis of the right renal artery and complete occlusion of the left renal artery. The stenosis of the right renal artery and the occlusion of the left renal artery produced the renovascular hypertension. She underwent aorta-aortic bypass for the coarctation of the abdominal aorta and aorta-renal bypass for treatment of renovascular hypertension Postoperatively, both femoral pulses were equally palpable. On discharge, antihypertensive drugs were discontinued. She has remained normotensive for last one year.

A 15 years Old girl was admitted with chief complaints of intermittent claudication of lower extremity, dizziness, and headache for 5 years. On admission, malignant hypertension was noted in the upper part of body [190-150/120-110] but femoral & dorsalis pedis pulse could not palpate. Once she had experienced C. V. A. due to hypertension of upper part, about years ago. On auscultation, systolic murmur was audible along the left sternal border. E.C.G. Showed left ventricular hypertrophy pattern, and others within normal limit. Retrograde aortography demonstrated diffuse narrowing of entire thoracic aorta with underdeveloped lower abdominal aorta [below the renal artery] & both common lilac artery, and rich collaterals, but normally visualized greater arteries in the aortic arch. On left posterolasteral thoracotomy, entire descending thoracic aorta revealed marked narrowing with mild perivascular adhesion, but no mediastinal pleura adhesion. These findings suggest as congenital type of atypical coarctation in the entire thoracic aorta with mild secondary change. But histopathology was showed the findings of chronic non-specific aortitis, later. Dacron by pass graft was performed with end to side anastomosis between graft and aortic wall. After operation, all her preoperative symptoms & signs were disappeared, and discharged with good general condition.

배경: 심장 내 기형을 동반하지 않는 단순 대동맥 축착은 이미 수술적 치료가 안정화되었으나 수술의 성공 여부와 관계없이 고혈압, 재축착 등의 부작용이 적지 않은 질환이다. 본 연구에서는 본원에서 단순 대동맥 축착의 교정술을 시행 받은 환자들을 대상으로 부작용의 발생 정도 및 교정 방법에 따른 차이에 대해 알아보고, 이에 영향을 미치는 인자들을 분석해 보고자 한다. 대상 및 방법: 1991년 2월부터 2006년 2월까지 본원에서 단순 대동맥 축착으로 수술을 시행 받은 총 50명(남 33명, 여 17명)을 대상으로 하였다. 환자들의 연령은 생후 5일부터 53세까지 다양하였고, 수술 시기 및 집도의에 따라 확장 단단문합술, 인공혈관 치환술 및 패치 대동맥 성형술 등으로 수술하였다. 이들을 연령별, 수술방법 등에 따라 나누어 수술결과 및 부작용 발생 등을 비교하였다. 결과: 수술 후 수술과 관련된 사망 환자는 없었고, 현재까지 수술 문합 부위에 대동맥류가 발생한 환자도 없다. 고혈압은 전체의 22% 인 11명에서 관찰되었는데, 연령별로는 소아/성인군(52.4%)이 신생아/영아군(0%)보다 높은 유병률을 보였고, 수술 방법별로는 인공혈관 치환술(Graft interposition)군 (88.9%)에서 확장 단단문합술(Extended end to end anastomosis)군(5.3%)보다 유의하게 많이 관찰되었다. 재협착의 경우 신생아/영아군(6.9%)과 소아/성인군(9.5%)에서 발생률의 차이가 없었고(p=0.5), 수술 방법에 따라서도 유의한 차이를 보이지 않았다. 결론: 단순 대동맥 축착의 경우 근래에는 수술 후 사망률이나 이환율은 매우 적지만, 술 후 장기 추적 관찰에 의하면 고혈압이나 재협착 등이 적지 않게 발생하고 그로 인한 심혈관계 질환이 문제가 되므로 지속적인 관찰과 적극적인 치료가 필요할 것으로 생각된다.

An 18-day-old male neonate with hypoplastic left heart syndrome underwent surgical intervention by modification of the Norwood procedure on September 23, 1986. Hypoplastic left heart syndrome is a serious congenital cardiac anomaly that has a fatal outlook if left untreated. Included in this anomaly are [1] aortic valve atresia, and hypoplasia of the ascending aorta and aortic arch, [1] mitral valve atresia or hypoplasia, and [3] diminutive or absent left ventricle. Patent ductus arteriosus is essential for any survival, and there is usually a patent foramen ovale. Coarctation of the aorta is frequently associated with the lesion.z With a limited period of cardiopulmonary bypass, deep hypothermia, and circulatory arrest, the ductus arteriosus was excised. The main pulmonary artery was divided immediately below its branches, and the distal stump of the divided pulmonary artery was closed with a pericardial patch. The aortic arch was incised, and a 1 5mm tubular Dacron prosthesis was inserted between the main pulmonary artery and the aortic arch. A 4mm shunt of polytetrafluoroethylene graft was established between the new ascending aorta and the right pulmonary artery to provide controlled pulmonary blood flow. Following rewarming, the heart started to beat regularly, but the patient could not be weaned from cardiopulmonary bypass. At autopsy, the patient was found to have hypoplasia of the aortic tract complex with mitral atresia and aortic atresia. A secundum atrial septal defect was noted. Right atrial and ventricular hypertrophy was present, and the left ventricle was entirely absent. Although unsuccessful in this case report, continuing experience with hypoplastic left heart syndrome will lead to an improvement in result.

We have recently experienced a rare case of abdominal aortic injury caused by deceleration force during fall in upright position. The patient was 43-year-old brick-layer fell from 12 meter height and sustained compression fracture of the spine and both legs. The aortic injury was unnoticed at that time. About 2 years later, marked stenosis of the distal abdominal aorta was found together with clinical manifestations of ischemia of both legs. Aorto-femoral bypass on both sides has completely relieved the symptoms, Similar type of abdominal aortic injuries could not be found in the literatures.
