Dry puncturing method of dry pericardium

Abstract

The invention discloses a dry puncturing method of dry pericardium. The dry puncturing method comprises 3 steps of step 1, performing preparation before operation; step 2, selecting puncturing body positions, wherein the puncturing body positions are the left front positions; and step 3, performing a pericardium puncturing process. According to the dry puncturing method of dry pericardium disclosed by the invention, through analyzing characteristics of heart, musculus diaphragm, xiphoid process, a breastbone anatomic structure and X ray imaging, appropriate puncturing positions and appropriateneedle injection angles are selected, and under the guidance of an appropriate X ray image, under the premise that a contrast agent is not used, the pericardium puncturing process is finished, and apassage is established for epicardial mapping and ablation.

Description

technical field [0001] The invention relates to a dry puncture method for dry pericardium. Background technique [0002] Ventricular tachycardia (referred to as ventricular tachycardia) is a serious rapid arrhythmia, and antiarrhythmic drug treatment is usually ineffective, failing to significantly improve the prognosis and reduce the mortality rate. Transcatheter radiofrequency ablation is one of the effective treatment methods for ventricular tachycardia. However, related studies have found that 5% to 30% of patients with ventricular tachycardia may have lesions originating from the epicardium. Traditional endocardial mapping and radiofrequency ablation cannot be successful, and pericardial puncture is often required for epicardial ablation to succeed. . The conventional route for epicardial ablation is percutaneous subxiphoid pericardiocentesis, but the popularity rate is low, the risk is high, and the operation method is not uniform, especially for dry pericardiocentes...

Problems solved by technology

The traditional pericardiocentesis requires puncture while imaging, commonly known as conventional pericardiocentesis, because this puncture method uses a contrast agent, in order to distinguish it from this puncture method, it is called wet wet pericardiocentesis, which is easy to cause blurred surgical field of view, easy to Complications such as right ventricular wall perforation, strayed into the pulmonary valve or penetrating into the pleural cavity, especially prolonging the learning curve for new operators
