Coarctation of the aorta is rare condition among the congenital cardiovascular defects in Korea. We experienced one case of coarctation of the aorta [postductal type], which was successfully corrected with Dacron graft. This 20 year old man was admitted to our hospital for evaluation of hypertension in the upper extremities and frequent occipital headache of 2 month duration. On physical examination, grade II systolic murmur was heard over the apex and mid back, but thrill was not palpable. Blood pressures were measured at both extremities, its values were 190/70mmHg. in the arms and 120/60mmHg in the legs. Routine chest roentgenogram showed the dilated left subclavian artery high on the left mediastinal border and associated with left ventricular prominence, but notchings of lower border of rib was not seen. Electrocardiogram also showed left ventricular hypertrophy. Final Pre-operative diagnosis was made by the aortic catheterization and aortography, which showed the typical configuration of postductal type of coarctation with poststenotic dilatation of aorta. Under the moderate hypothermia by surface cooling, coarcation was resected 3.5cm in length and then Dacron graft was inserted. After prosthetic correction, blood pressures were recorded 120/60mmHg in arms and 160/120mmHg in legs. The post-operative course was uneventful.

Coarctation of aorta is rather common congenital cardiovascular disease in the western contries, but it is known to be less than 2 % in Korea. From June 1986 to December 1992, seven patients of surgically treated coarctation of aorta who were less than 2 years old, were experienced at Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The patients included six male and one female, with ages in the range of one month and 24 months. Four patients were preductal type and three juxtaductal. Associated cardiac anomalies were present in all patients and they were PDA[6 cases], ASD[3], VSD[2], bicuspid aortic valve[2], aortic stenosis[1], mitral regurgitation[1], and tricuspid regurgitation[1]. The operative procedures were four end to end anastomosis and three subclavian flap aortoplasty. Mean aortic cross clamping times were 37.3 minutes in patients with end to end anastomosis and 30.3 minutes in patients with subclavian flap aortoplasty. There were two operative deaths in patients who were treated with subclavian flap aortoplasty and pulmonary artery banding. One patient who had been treated with subclavian flap aortoplasty was complicated with postoperative mild paraplegia in lower limb. Pulmonary artery banding has been disappointing in our patients, and the data was suggestive that earlier total repair of complicated coarctation might improve survival.

Development of an aneurysm in the thoracic aorta, intercostal arteries, or cerebral vessels is not an uncommon occurrence in patients with coarctation of the aorta. The mechanism whereby coarctation predisposes to aneurysm formation is incompletely understood and we suggest that in this case, an intrinsic factor in the wall of the aorta underlies the formation of aneurysms. Recently we experienced one case of COA associated with the thoracic aortic aneurysm and operation was done successfully. PDA was simply ligated and the aorta was cross-clamped proximally and distally and the area of constriction or aneurysmal site were excised. Postoperative course was uneventful and the patient was discharged 2 weeks after operation. Hypertension at upper extremities was controlled without any antihypertensive drugs after operation and the degree of regurgitation of mitral valve was improved postoperatively but long-term follow-up should be necessary.

This is a report of a. case in which a long narrow segment coarctation of the aorta was successfully corrected with Teflon graft. The patient was 30 year old man with hypertensive symptoms that occurred 7 years prior to operation. Blood pressure measured 230/110 mmHg in the arms and 110/80 mmHg in the legs. Pulses were strongly tensive in radial artery, but very weak in femoral artery and even absent in dorsal pedis artery. Final preoperative diagnosis was made by aortography which showed a long narrow segment between aortic arch and descending thoracic aorta and highly developed collateral circulations. A long hypoplastic narrow segment was located proximal to the ligament arteriosus, and diaphragmatic stenosis of the aorta was located just distal to the ligamentum arteriosus. After prosthetic correction of the coarctation of the aorta, blood pressure were measured 130/ 80 mmHg in the arms and 150/100 mmHg in the legs. Peripheral pulses were palpated normally, and the postoperative course was uneventful.

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.

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 the aorta is a congenital constriction of the aorta of varying degree usually located slightly distal to the origin of the left subclavian artery. This congenital malformation is found at 5-9% of the congenital heart disease in Europe & North America, but in our country, it is reported as one of rare malformations. We present a case of coarctation of the aorta, which had double diaphragms as discrete form. This is 9 year-old boy, who has suffered from hypertensive symptoms since 6 years before. Coarctation of the aorta was confirmed by aortography, and there was no combined anomalies, and it was postductal type, and coarctations were consisted of two diaphragmatic webs at the both ends with a central aneurysmized. After resection of the coarctated segment completely, Woven Dacron graft was inserted with 18mm in diameter & 2.5cm in length successfully.

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.
