ABSTRACT
Coronary artery bypass grafting (CABG) has been a standard revascularization method for three-vessel disease and left main coronary artery disease since its development in the 1950s. In recent years, with the development of basic research, clinical diagnosis, surgical instruments, and interdisciplinary work, significant progress has been made in the surgical approaches, saphenous vein graft harvesting, and secondary prevention during the perioperative period. This article reviews the surgical methods of coronary artery bypass grafting, the development status and hot issues of perioperative secondary prevention.
ABSTRACT
Surgery is preferred for treating stage I non-small cell lung cancer (NSCLC). The main factors that affecting its prognosis are tumor metastasis and recurrence. In recent years, studies have revealed that the main cause of death in patients with stage I NSCLC is micrometastasis of lymph nodes. Micrometastasis has become a hot topic in modern precision medicine. Detection of micrometastasis as early as possible, early intervention and accurate assessment on prognosis of lung cancer have a great impact. The concept, methods and markers for clinical detection, as well as prognosis and adjuvant therapy of lymph node micrometastasis are reviewed in this article.
