Endoscopic vein harvest of the greater saphenous vein for aortocoronary bypass grafting presents a relatively newer and less invasive mode of vein harvest that has become a more popular approach used in the field of cardiac surgery. This study aimed to compare the long-term patency of saphenous vein grafts and clinical outcomes (a minimum of 10 years) after endoscopic harvest with open vein harvest in patients after isolated surgical myocardial revascularization. Fifty patients (25 after endoscopic and 25 after open harvest) who underwent isolated myocardial revascularization between 2009 and 2011 assessed. The study comprised two phases: completion of questionnaires assessing recurring symptoms of ischemic heart disease and visualisation of vein grafts via coronary computed tomography angiography to assess graft patency. The primary outcome showed higher patency rates after open vein harvest (76.1 vs. 68.8%); without significant statistical difference (p=0.873). Differences in clinical outcomes were not statistically significant regarding recurring angina (28% endoscopic group, 32% open group, p=0.519), dyspnea (24 vs. 16%, p=0.817) and myocardial infarctions with catheterbased revascularization of vein grafts (8% endoscopic group, 16% open, p=0.734). Redo surgery was not reported in neither group. Endoscopic and open vein harvest yielded comparable long-term patency rates both angiographically and clinically. That strenghtens endoscopic approach as a non-inferior mode to the traditional approach in patients undergoing surgical myocardial revascularization.

OBJECTIVE: This study aimed to evaluate our experience with the use of Magseed, the magnetic metallic marker, as a localization technique followed by Sentimag probe detection in patients with solitary intra-abdominal local metastases with subsequent resection of the lesions.METHODS: Five patients underwent resection after the lesion was marked with the Magseed magnetic marker. Prior to the surgery, a computed tomography scan of the chest and abdomen and/or positron emission tomography was performed to rule out the dissemination of the disease. The indication for surgery was evaluated in a meeting of a multidisciplinary team, and the placement of the magnetic marker under computed tomography control had been performed the day before the planned procedure. RESULTS: The present preliminary outcomes have revealed that Magseed might be a promising technique that is feasible and safe, particularly when the postsurgical anatomic conditions in the abdominal cavity are altered and the lesions are not visible or palpable. Surgical extirpation of lesions occurred without complications in each case. In all the cases, the resection was complete and curative, and one wound infection in all (20%), without any major complications, had occurred. The mean hospital stay was 6.6 days.CONCLUSION: Magseed utilization, as a localization technique, followed by Sentimag probe detection in intra-abdominal tumors has not been reported before. Improving the visualization and, consequently, the precise marking of the lesion with subsequent radical removal can prevent insufficient or excessive removal of healthy tissue, leading to a faster diagnosis and better overall clinical outcomes.
