Results of emergency coronary artery bypass grafting for acute myocardial infarction: importance of intraoperative and postoperative cardiac medical therapy.
The results of emergency coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI) are less than satisfactory, and readmission for cardiac events is common. ⋯ Early results of this study are similar to those seen in previous reports, whereas late phase results yield some new and interesting findings. We suggest that intraoperative hANP, and postoperative aldosterone blocker and ARB, following CABG for AMI, will, through control of the renin-angiotensin-aldsterone system, inhibit left ventricular remodelling, reduce the extent of infarction, and improve cardiac function, yielding a favourable long-term prognosis.

Case ReportsApico-aortic conduit for aortic stenosis in a patient with chronic thoracic wall infection.
We report a case of an apico-aortic bioprothesis-valved conduit for a 70-year-old-woman with symptomatic, severe aortic stenosis and severe calcification of the ascending aorta. She had a history of mastectomy and radiation therapy for breast cancer and was suffering from radiodermatitis and chronic thoracic wall infection. Transthoracic echocardiography showed severe aortic valve stenosis with heavy calcification and high aortic valve pressure gradients. ⋯ We underwent apico-aortic bypass with a hand-made composite graft: 19-mm bioprosthetic valve and a 22-mm woven polyester vascular graft. The surgical intervention successfully decreased pressure gradient across the aortic valve, also separating an incision from chronic infection allowed us to avoid postoperative mediastinitis. The patient had remained in good condition for 15 months without developing any complications.

Case ReportsRib fixation for severe chest deformity due to multiple rib fractures.
The operative indications for rib fracture repair have been a matter of debate. However, several reports have suggested that flail chest, pain on respiration, and chest deformity/defect are potential conditions for rib fracture repair. We describe our experience of rib fixation in a patient with severe chest deformity due to multiple rib fractures. ⋯ Operative findings revealed marked displacement of the superior 4 ribs, from the 2nd to the 5th, and collapse of the osseous chest wall towards the thoracic cavity. After exposure of the fracture regions, ribs fixations were performed using rib staplers. The total operation time was 90 minutes, and the collapsed portion of the chest wall along the middle anterior axillary line was reconstructed successfully.

Case ReportsMalignant solitary fibrous tumor of pleura accompanied with first symptoms of chest pain and hemoptysis: a case report.
Solitary fibrous tumor of the pleura (SFTP) is a rare tumor especially presents malignant features. Such symptoms of hemoptysis and dyspnea were rarely seen and take 5% and 4% respectively in malignant SFTP. A 26-year-old Chinese man, presenting with hemoptysis in the emergency room, was hospitalized because of dyspnea. ⋯ There was at least a 5000-ml mixture of blood and tumor tissue in the right chest cavity because of continuous bleeding, leading to a tumor capsule split. Histopathology and immunohistochemistry identified the tumor as malignant SFTP, but CD34 was negative. In this case, the tumor grew rapidly and aggressively in two months, indicating that close follow-up and active treatment are needed.

Comparative StudyShould right coronary bypass grafts be anastomosed proximal or distal to the crux? A comparison of graft patencies.
Late occlusion of bypass grafts is one of the main issues associated with long-term survival after coronary artery bypass grafting (CABG) surgery. Left coronary system is generally revascularized using arterial conduits, whereas saphenous venous grafts are used for right coronary system. We investigated the prognostic factors that are related to the patency and risk of occlusion of saphenous venous grafts used for revascularization of diseased right coronary arteries. ⋯ Based on the results of our study we suggest that even though an appropriate segment for anastomosis is available proximal to the crux of the RCA, right posterior descending artery (PDA) should be preferred for revascularization when RCA is the target vessel in CABG.
