A proposal for a comprehensive approach to infections across the surgical pathway.

Despite evidence supporting the effectiveness of best practices in infection prevention and management, many healthcare workers fail to implement them and evidence-based practices tend to be underused in routine practice. Prevention and management of infections across the surgical pathway should always focus on collaboration among all healthcare workers sharing knowledge of best practices. To clarify key issues in the prevention and management of infections across the surgical pathway, a multidisciplinary task force of experts convened in Ancona, Italy, on May 31, 2019, for a national meeting. This document represents the executive summary of the final statements approved by the expert panel.

Saphenous Vein Graft Wrapping by Nitinol Mesh: A Word of Caution.

BACKGROUND: Saphenous vein conduits are still used in a large proportion of coronary artery bypass graft (CABG) operations. A recently commercialized nitinol mesh seems to improve venous graft patency. The aim of this study was to control nitinol mesh vein graft patency in a series of isolated CABG patients by computed tomographic (CT) scan. METHODS: In 25 patients (mean age: 61.0 ± 9.65 years), operated for isolated CABG, the eSVS nitinol mesh (Kips Bay Medical Inc., Minneapolis, Minnesota, United States) was used to wrap one vein graft in each patient. Nitinol mesh vein graft was used to revascularize the right coronary (4 patients; 16%), the posterior descending (18 patients; 72%), and the obtuse marginal (3 patients; 12%) arteries. CT scans were performed at 1, 6, and 12 months postoperatively. RESULTS: The procedure was uneventful in all patients. CT controls showed an overall patency rate of 86.9, 42.7, and 34.1% at 1, 6, and 12 months, respectively. The 4 mm mesh had a significantly higher patency rate at 12 months (83.33%) than the 3.5 mm one which showed quite unsatisfactory results (20%) (p = 0.02). Patients with graft occlusion underwent stress testing which was mildly positive in two cases. One of them underwent a percutaneous revascularization. CONCLUSION: Despite promising early results, use of nitinol mesh for saphenous veins was disappointing in our experience. Further refinements are probably needed.
