While popliteal artery aneurysm is the most common form of peripheral artery aneurysm, it is a rare condition in the general population. Furthermore, a giant popliteal artery aneurysm has not previously been reported in Korea. A 67-year-old male presented with left thigh pain that had begun 4 months earlier and was aggravated when in a sitting position. We found a giant aneurysm on the left popliteal artery and performed a bypass from the common femoral artery to the distal popliteal artery below the knee, using the autologous greater saphenous vein, and excluded the aneurysm at the sites of anastomoses.

A right coronary artery to left ventricular fistula with a giant right coronary artery aneurysm is a very rare condition. This requires surgical treatment because of the possibility of rupture of aneurysm, heart failure and infective endocarditis. A 47 years old male patient with dyspnea on exertion for 3 months was diagnosed as having a right coronary artery to left ventricular fistula with a giant right coronary artery aneurysm according to the CT and coronary artery angiography. We resected the aneurysm and performed a coronary artery bypass graft.

Background: For the treatment of isolated left main coronary artery disease, twelve arterial revascularizations with Y-composite grafts using left internal thoracic artery and radial artery or right gastroepiploic artery were peformed. This study was performed to investigate whether V-composite graft can satisfy the blood flow required to make myocardium act properly or not. Borderline stenotic lesions on the left main coronary artery, which are very prone to remodel the bypassed vessels due to competitive flows, were also considered. Material and Method: Among 247 patients who underwent coronary artery bypass grafting from March 2000 to April 2003, 12 patients (4.7%) who had received total arterial revascularizations for the isolated left main coronary artery disease were studied retrospectively. Result: left anterior descending arteries were bypassed with left internal thoracic artery by off-pump technique in all patients, however, 2 cases of left obtuse marginal branches were bypassed under on-pump beating heart. Except for one patient, who did not have an obtuse marginal branch more than 1 mm in diameter, 11 patients had gone through complete arterial revascularizations by use of the Y shape arterial graft. Among five patients who had less than 75% stenosis, one patient showed string sign on left internal thoracic artery grafted to left anterior descending artery. However, two grafts to obtuse marginal blanches were completely obstructed and one showed slender sign. There were no graft-dominant flow in patients with stenotic lesion less than 75%. On the contrary to the result of patients with stenotic lesions less than 75%, all the patients with stenotic lesions more than 90% showed graft-dominant blood flow. Conclusion: In conclusion, it is assumed that, when stenotic lesions are over 90%, coronary artery bypass grafting with an Y shape arterial graft could possibly give enough help to the obstructed coronary arteries in blood supplying to myocardium, which needs massive quantity of blood to act well. However, when patients have borderline stenoses, through scrupulous examinations, more prudent and flexible decisions are required in choosing the treatment methods, such as, direct anastomosis of vein or artery to aorta, or adding supplementary treatment methods like percutaneous coronary intervention, rather than choosing a fixed treatment methods.

Background: The survival benefit of coronary artery bypass grafting (CABG) using the bilateral internal thoracic arteries (BITA) is well known; however, the role of BITA in concomitant aortic valve replacement (AVR) and CABG has not been studied. Methods: We retrospectively reviewed patients who underwent concomitant AVR and CABG. Cases not using an internal thoracic artery and less than 2 bypass grafts were excluded. We enrolled 114 patients in this study. The mean follow-up duration was 61.5±43.5 months. Results: Forty patients (35.1%) underwent CABG with a single internal thoracic artery (SITA) and 74 patients (64.9%) underwent CABG with BITA. The preoperative clinical characteristics were not significantly different between the 2 groups, with the exception of a higher prevalence of atrial fibrillation in the SITA group. Postoperative mortality and morbidity were not significantly higher in the BITA group than in the SITA group. In the univariable analysis, the survival of the BITA group was similar to that of the SITA group (p=0.157). Multivariable analysis showed that only mean age was a predictor of death (p=0.042), but using BITA was not an independent predictor (p=0.094). In low-risk patients whose preoperative ejection fraction was >45%, the survival of the BITA group was significantly better than that of the SITA group (p=0.043). Conclusion: BITA use in concomitant AVR and CABG showed no difference in mortality compared to using SITA. Although its impact on long-term survival was inconclusive, BITA use can be considered for low-risk patients.

Bronchopulmonary sequestration (BPS) is a rare congenital abnormality of the lower airway, generally characterized by blood supply received from the systemic circulation. We present a rare case of a 19-year-old man with incidentally detected BPS supplied by a branch of a pulmonary artery, rather than a systemic artery. Computed tomography showed a sequestered segment supplied by a branch of the left pulmonary artery and containing an ectopic bronchus. As chest computed tomography revealed necrosis in the sequestered tissue, infection was presumed, and the tissue was surgically removed. This may represent a very unusual occurrence, as such cases have yet to be reported in the literature.

Anomalous origin of a coronary aortic artery is a rare cardiac anomaly. Although it can cause angina, syncope, and palpitations, most patients are asymptomatic. This anomaly requires surgical treatment or intervention because it is associated with sudden death. Several surgical techniques, such as coronary reimplantation, coronary artery bypass grafting (CABG), unroofing, and neo-ostium formation, have been proposed as treatments. We report a case surgically treated with neo-ostium formation in anomalous origin of the left coronary artery from the right coronary sinus.

Moyamoya disease (MMD) is characterized by progressive steno-occlusive lesions of the distal or proximal branch of the internal carotid arteries, and cerebrovascular symptoms are its major complications. Extracranial vascular involvement including the coronary artery has been reported, and some case reports have described variant angina or myocardial infarction. However, no report has yet described a case of myocardial infarction after coronary artery bypass grafting (CABG). Here, we present a patient with MMD who suffered cardiac arrest caused by myocardial infarction due to a coronary spasm after offpump CABG and who was discharged successfully after treatment with a veno-arterial extracorporeal membrane oxygenator and percutaneous coronary intervention.

A rupture of an innominate artery caused by blunt trauma is relatively rare because this artery is short and protected by the chest bony cage. This report describes a 25-year-old man who suffered a traffic accident, that resulted in an innominate artery rupture, which was detected by a chest computed tomogram and angiogram. This patient underwent urgent surgery through a right clavicular incision and median sternotomy without a cardiopulmonary bypass due to multiple injuries. An approximately 3 cm sized injury was found from the innominate artery to the proximal right subclavian artery and the origin of the common carotid artery. The injured lesion was repaired with a saphenous vein patch. After surgery, he was discharged from hospital without complications.

Single coronary artery is rare congenital anomaly with incidence about 0.04%. Above half of single coronary artery is symptomless, and about 41% of cases are associated with another congenital cardiac anomalies . Single coronary artery is sometimes important for cardiac operation to avoid fatal result from cutting of coronary artery during the right ventriculotomy. Among the associated anomaly of the single coronary artery, coronary arteriovenous fistula is very rare. We experienced congenital single coronary artery with coronary arteriovenous fistula drained into the right ventricle, and so we report this case with literatures.

A coronary artery fistula (CAF) is an abnormal vascular connection between the coronary arteries and the cardiac chambers or major vessels. Although rare, CAFs can lead to substantial coronary morbidity and mortality. This study outlines the surgical management of a CAF originating from the left coronary artery and connecting to the right atrium, in a patient experiencing angina with a marked left-to-right shunt. The surgical approach involved ligation of the coronary artery and reduction of the aneurysmal portion, resulting in the patient's uneventful recovery.
