Brixia system of screws: a titanium modular system with wide applicability for reinforced sternal closure in cardiac and thoracic surgery.

The use of cannulated screws and titanium plates to reinforce the sternal closure or to treat sternal dehiscence after median sternotomy has already been suggested in several articles. The system proposed here has some important advantages over those already described. Moreover, thanks to its characteristics, this system can also be used to treat pathologies affecting the entire rib cage. The system consists of a first threaded cannulated screw that is inserted in the bone or chondral cartilage and accommodates a cap screw that is tightened into the first screw and fixes a plate according to the following scheme: a threaded cannulated screw/plate/cap screw (Brixia system of screws). This system allows the plates to be fixed on the anterior face of the ribs and/or sternum without the need to enlarge dissection of the tissue, thereby lowering the danger of haemorrhage and injury to the thoracic organs. For this reason, it is particularly suitable for treating post-sternotomy sternal dehiscence, but it can be used to reinforce the primary sternal closure (after median or transversal sternotomy) in high-risk patients with sternal dehiscence. Owing to the modular nature of the system, singular components can also be utilized independently.

Thoracoscopic AF ablation in situs inversus dextrocardia with interrupted inferior vena cava continuation in azygos vein.

INTRODUCTION: Situs inversus totalis, dextrocardia with interrupted inferior vena cava, and azygos vein continuation concomitant with symptomatic atrial fibrillation requiring ablation. This case was deemed not suitable for percutaneous ablation due to anatomic variations and the lack of case reports in the literature. METHODS AND RESULTS: We performed bilateral thoracoscopic epicardial ablation and epicardial left atrial appendage exclusion. The direct vision allowed for a complete box lesion set with bipolar radiofrequency device. Patient remained in sinus rhythm at the 12-months follow-up. CONCLUSION: Surgical thoracoscopic epicardial ablation is safe and effective also in congenital defects. Multidisciplinary expertise can offer minimally invasive ablation treatments.
