A 68 year-old man visited our institution due to chest pain. Coronary angiography revealed triple vessel disease. A computed tomographic angiogram performed as a routine preoperative examination demonstrated an intraluminal spider-web-like mass from the infrarenal abdominal aorta to both common iliac arteries. The infrarenal aorta and both common iliac arteries were excised and replaced with concomitant off-pump coronary artery bypass grafts. Histologic examination of the aorta suggested an intimal sarcoma. A postoperative computed tomographic angiogram performed 3 months postoperatively showed no evidence of a residual or a recurred lesion.

Objective : This study was conducted to determine an association between aortic calcification viewed on plain chest radiography and obstructive coronary artery disease. Method : Retrospective review of all chest radiography obtained from consecutive patients undergoing coronary angiography. Chest PA images were reviewed by technical radiologist and radiologist. Considering the presence of aortic arch calcification, images were compared with the results of coronary angiography. In addition, the size of aortic arch calcification were divided into two groups - the smaller and the larger than 10 mm. Results : Among the total 846 patients, the number of the patients with obstructive coronary artery disease is total 417 (88.3%) in males and 312 (83.4%) in females. Considering the presence of aortic arch calcification, the positive predictive value of relation between aortic arch calcification and obstructive coronary artery disease was 91.4% and the relative risk of the group with aortic arch calcification to the opposite group was 1.10. According to the size of aortic arch calcification and obstructive coronary artery disease, the positive predictive value was 91.9% and the relative risk between two groups was 1.04. Conclusions : This study shows that aortic calcification was closely associated with obstructive coronary artery disease. If the aortic calcification is notified on plain chest radiography, we strongly recommend to consult with doctor.

매우 드물게 발생하지만 대동맥판막수술중에 우관상동맥의 급성폐색은 우심실부전을 일으켜 매우 치명적인 결과를 초래할 수 있다. 심한 대동맥 판막부전증을 가진 67세 여자 환자에서 19 mm Hancock II 조직판막을 이용하여 대동맥판막치환술을 시행한 후 심폐기에서 이탈하는 과정주에 우심실부전이 발견되었으며, 우관상 동맥의 폐색을 의심하여 우측 내흉동맥을 사용하여 관상동맥 우회수술을 시행하였고 이후에 심폐기에서 순조롭게 이탈할 수 있었다. 수술후 9일째 시행한 관상동맥 조영술에서 우관상동맥 근위부에 색전에 의한 폐색을 확인할 수 있었다. 이에 저자들은 우관상동맥의 폐색으로 인한 우심부전증이 우관상동맥우회수술후에 회복된 증례를 보고하고자 한다.

Nonocclusive mesenteric ischemia (NOMI) is a rare complication that occurs in about 0.05% of patients after openheart surgery, and NOMI refers to the mesenteric ischemia that's caused by splanchnic vasospasm without occlusion of the great intestinal vessels. In the presently reported case, NOMI developed to maintain the blood flow to the heart and brain after several minutes of a hypotensive status and the latter was caused by acute aortic dissection that complicated an aortic cannulation procedure. Unfortunately, the patient died even though the problems were diagnosed early and proper treatment was administered. Early diagnosis of NOMI by angiography and the selective infusion of vasodilators are thought to be the only way to improve survival for patients with clinically suspected NOMI.

We experienced a case of aneurysm of the sinus of Valsalva dissecting into the ventricular dseptum. This dissection was induced by paravalvular leakage after aortic and mitral valve replacement. This 37-year-old male was admitted via emergence room due to progressive dyspnea. He had undergone aortic valve replacement(carbomed c" 23 mm) and mitral valve replacement(carbomedic 31 mm) due to aortic regurgitation and mitral regurgitation about 6 years prior to admission and followed up regularly. The diagnosis was made by transthoracic and transesophageal echocardiography and reconfirmed by root aortography. The inlet of the ventricular septal aneurysmal sac was repaired by one layer suture with 3-0 prolene of the endocardium, epicardium and homograft muscle shoulder altogether. Postoperative course was uneventful and the patient was discharged on the 11th postoperative day. day.

A 49-year-old woman had thoracic back pain for several years. Chest CT scan and MRI angiography revealed descending thoracic aortic aneurysm with a maximum diameter of 69 mm. Thoracic aortography showed not only the aortic aneurysm, but also coarctation of descending thoracic aorta at the level of aortic hiatus of the diaphragm. Intercostal artery arising Adamkiewicz artery was found in descending thoracic aortic aneurysm just above the coarctation, The aneurysm with coarctation of the aorta was successfully repaired with prosthetic graft replacement under left atrio-femoral bypass.

The main cause of ischemic heart disease combined with aortic valve disease is the systemic atherosclerotic process. Coronary artery embolism by a particle from the calcified aortic valvular tissue is very rare. A 73-year-old female patient was admitted due to chest tightness of recent onset. Two dimensional echocardiogram showed severe calcific aortic valve stenosis. Preoperative coronary angiogram exhibited a stenotic lesion at the distal right coronary artery, which seemed to be embolic in origin. The coronary embolus was removed through the coronary arteriotomy and then the arteriotomy site was repaired by onlay patch angioplasty technique. Aortic valve was replaced by a bioprosthetic valve. The embolus was reported as a fibrocalcified particle of diseased valve.

We experienced a case of anomalous origin of right pulmonary artery from the ascending aorta associated with pulmonary atresia, ventricular septal defect, absence of left pulmonary artery afld multiple major aortopulmonary collateral artery (MAPCA). At ten month of age, left pulmonary artery creation with unifocalization and right pulmonary artery banding were performed as the Urst stage, followed by coil embolization of right MAPCA 1 month later, and 1 year later, the total correction was done. After total repair, the patient showed good postoperative course and excellent angiographic and hemodynamic results at 1 year follow-up study.

A 56 years old male patient adklitted to our neurology department because of repeated tingling sensation in right 3, 4, 5th. (infers and weakness on grasping, which were progressively developed re ently. At this time, he had also suffered from claudication in both lower extremities. Carotid angiogram showed that right internal carotid artery was obstructed completely, and both common, both external and left internal carotid arteries had significant stenosis, Concommitantly, aortogram suggested complete obstruction just below the renal arteries. We plamled staged operation for two separated arterial lesions. Both carotid endarterectomy was performed. and we used carotid shunt for left side during operation. Abdominal aortic lesion was operated 2 weeks later We obligately clamped aorta just below the celiac artery and infuse4 kidney perservation solution to pertect kidney during ischemia. Reversed Y bypass graft and kidney perservation was successful despite of 40 minute ischemia. Postoperative courts was uneventful and patient was discharged without any specific problem.
