Subtle-discrete aortic dissection without bulging of the aortic wall. A rare but lethal lesion.

We report a subtle-discrete aortic dissection, without bulging of the aortic wall or aneurysm or valve pathology or periaortic effusion, which resulted in a lethal cardiac tamponade to a 35-year-old male.

Video-assisted lung resection using radiofrequency ablation in a porcine model.

Background: The aim of this study was to assess the feasibility, efficacy, and safety of video-assisted lingula resection using radiofrequency ablation (RFA) with internally cooled electrodes in a porcine model.

Materials And Methods: Six domestic pigs underwent RFA-assisted thoracoscopic lingulectomy. RFA was the only aerostatic and hemostatic method applied throughout the operation.
