Kommerell's diverticulum is a rare congenital abnormal aortic development. The diverticulum can occur in both left and right aortic arches, from which an aberrant subclavian artery rises to the contralateral side. Only a small number of patients with Kommerell's diverticulum present symptoms. Dysphagia, dyspnea, chest discomfort and upper extremity blood pressure difference are common in adult patients. The risk of aortic dissection or aortic aneurysm rupture is higher in such patients than that in patients with normal aorta. Early surgical intervention is recommended to improve the prognosis. Treatment options include open surgical repair, hybrid operation and total endovascular repair. The choice of surgical method depends on the specific anatomy of patients, the patients' state and the preference of surgeons. This paper reviewed and summarized the surgical methods and early results of the treatment of Kommerell's diverticulum reported in the literature from 2015 to 2020.
Nowadays, the development of the medical instrument industry makes rapid changes in clinical practice. Hybridization of latest technology is playing an increasingly important role in the diagnosis and treatment of disease. Especially, the trend of the integration of three-channel hybrid technology in diagnosis and treatment of early lung cancer has become increasingly obvious. This paper will focus on the technical advance of the three-channel multi- mirror robot and its application in the diagnosis and treatment of early lung cancer.
