A coronary-bronchial artery fistula is a very rare congenital anomaly of the coronary artery whose etiology and pathogenesis have not yet been clarified. Most patients with coronary-bronchial fistulas are asymptomatic; however, some patients present with congestive heart failure, infective endocarditis, myocardial ischemia induced by a coronary steal phenomenon, or rupture of an aneurysmal fistula. Furthermore, patients with a coronary-bronchial artery fistula rarely manifest life-threatening hemoptysis due to the associated bronchiectasis. We report herein the case of a patient with a coronary-bronchial artery fistula who had bronchiectasis and a history of massive hemoptysis and myocardial ischemia.

internal thoracic artery is used in myocardial revascularization because of many advantages. However, it may not be appropriate in the usual extrapleural or intrapleural route, because it can be easily displaced and injured due to the slender and weak characteristics. We introduce here, a simple technique of repositioning the skeletonized left internal thoracic artery in a stable and straight course by creating a tunnel between the left lateral pericardium and thymic tissue.

We report the case of a newborn with a rare anatomic variation: a right aortic arch with a retroesophageal left subclavian artery and an anomalous origin of the pulmonary artery from the aorta. This variation was diagnosed using echocardiography and computed tomography, and we treated the condition surgically.

Bronchopulmonary sequestration (BPS) is a rare congenital malformation of the lower respiratory tract. Most intralobar BPSs are provided with an arterial blood via the thoracic or abdominal aorta but such a supply is rarely found in patients older than 50 years. We report a case of an intralobar BPS with a dual arterial supply from the celiac artery and thoracic aorta in a 50-year-old man presenting with a respiratory tract infection and haemoptysis. To our knowledge, this is the first case report of a BPS supplied by the celiac artery and thoracic aorta in a 50-year-old man.

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.

Tracheo-innominate artery fistula (TIF) is a rare, life-threatening complication of tracheostomy that makes it difficult to secure the airway due to massive bleeding, constituting a medical emergency. Therefore, most successful surgical treatments include innominate artery debridement and tracheal fistula repair. Herein, we report a case of successful surgical treatment of a TIF while maintaining cerebral blood flow through an artificial vascular graft.

The rupture of a renal artery aneurysm is a rare disease that is difficult to diagnose. Although we usually consider the appropriate treatment to be open laparotomy with aortic aneurysm surgery or stenting with graft insertion through intravascular intervention, thus far, there is no general consensus on the treatment protocol for renal artery aneurysm. Notably, ruptured renal artery aneurysm is a true critical emergency that may result in a fatal outcome. We are reporting two renal artery aneurysm patients who had ruptured and underwent emergency laparotomy.

Background: The Y-composite graft of internal thoracic artery and radial artery is commonly used in coronary bypass surgery. The aim of this study is to look for a way to raise the free flow of the internal thoracic graft and to see flow dynamics of the Y-graft. Material and Method: In 15 patients undergoing coronary bypass surgery, free flow of the in-situ internal thoracic artery graft was measured using two different papaverine application methods; extraluminal papaverine spray in 7 patients and intraluminal papaverine injection in 8. In 18 other patients for whom the Y-graft was used, total free flow and flow changes from the two ends were measured. Result: The free flow of the in-situ internal thoracic artery graft almost doubled with internal papaverine injection than with external papaverine spray $(47.7\pm9.6$ mL/min $vs.100.8\pm26.3$ mL/min, p<0.001). Total flow of the Y-composite graft was significantly more than either flow of the internal thoracic artery end or radial artery graft end $(173.3\pm45.3$ mL/min vs. $121.1\pm34.3$ mL/min or $117.5\pm42.8$ mL/min). When both ends of the Y-composite graft were opened, free flows from the two ends were similar $(85.4\pm27.8$ mL/min vs: $87.9\pm42.4$ mL/min, p=0.772). The flow of one end of the Y-composite graft was increased significantly by clamping of the other-end than when both ends were opened. Conclusion: Intraluminal papaverine injection is very effective in raising free flow of the internal thoracic artery graft, and the free flow of the Y-composite graft of in-situ internal thoracic artery and free radial artery graft is more than that of the in-situ internal thoracic artery graft. The flow of one end flow of the Y-graft may be altered by the flow change of the other end.

Chronic pulmonary artery thromboembolism is a relatively rare phenomenon causing hypoxia and pulmonary hypertension that eventually leads to respiratory failure and right heart failure. Patients with acute pulmonary artery thromboembolism are generally treated with antithrombotics and thrombolytics. However, in cases with chronic pulmonary artery thromboembolism the fibrinized thrombus is so strongly adhered to the pulmonary artery wall that medical treatment becomes ineffective and surgical treatment must then be considered. We report a 47year old patient, with a history of repeated admission due to unresolved chronic obstructive pulmonary disease and chronic pulmonary artery thromboembolism at a local hospital, who underwent a successful endarterectomy of pulmonary artery thromboemboli using intermittent total circulatory arrest.

Takayasu`s arteritis is one of chronic inflammatory disease characteristically involving the aorta and it`s major branches. We experienced two surgical cases of Takayasu`s arteritis associated with the stenosis of the descending thoracic aorta. One case was 15 year-old girl and she was admitted because of dyspnea on exertion for 12 months. Aortogram showed the stenosis of the descending thoracic aorta from just below left subclavian artery to the 9th thoracic vetebra. The other case was 10 year-old girl and she was admitted because of URI and hypertension. Aortogram showed narrowing of right innominate artery, but developed collateral circulation, and the stenosis of the descending thoracic aorta near the 9th thoracic vertebra. In each case, bypass graft from the ascending aorta to the abdominal aorta just above the inferior mesenteric artery was performed with satisfactory result.
