Objective To evaluate the 6 months efficacy and safety of cyanoacrylate closure for the treatment of incompetent great saphenous veins (GSVs) in comparison with radiofrequency ablation (RFA). Methods In this multicenter, retrospective, clinical trial, 398 symptomatic subjects with incompetent GSVs were assigned to either cyanoacrylate closure or RFA. The primary endpoint, complete closure of the target GSV, was determined using duplex ultrasound examination starting from one-, three-, and six-month visits. Results All patients were followed for 6 months and there was no difference between the groups in terms of mean follow-up time. Hospital stay and return to work/activity were shorter in the cyanoacrylate ablation (CAA) group, and these differences between the groups were statistically significant. Ecchymosis was observed higher in the RFA group and was statistically significant. Conclusions In this study, in which we examined the CAA and RFA methods, we found that both methods were effective and reliable; however, we found that patients in the CAA group had a more comfortable postoperative period and returned to work earlier.

Objectives: Atrial fibrillation (AF) is the most common arrhythmia encountered and is usually seen in patients scheduled for coronary artery bypass and mitral valve surgery. Radiofrequency ablation and cryoablation are two methods used in AF surgery and proven efficacy. In this study, cryoablation and radiofrequency ablation methods were compared in terms of clinical outcomes, efficacy and safety. Methods: Between November 2011 and September 2017; 99 patients with AF who underwent radiofrequency ablation or cryoablation during open heart surgery were included in this study with 2 groups. The patients who underwent cryoablation were defined as Group I (n = 40), and the patients who underwent radiofrequency ablation as Group II (n = 59). Preoperative, perioperative, early and mid (1 year) postoperative period characteristics of the groups were analyzed. Results: The mean age was 60.6 ± 9 years in Group I and 60.7 ± 9.1 years in Group II (p = 0.960). When the operative values were examined, ablation time and cross-clamp time was found to be low in Group II and a statistically significant difference was found (p < 0.001 and p = 0.043; respectively). When the rhythms of the postoperative first year controls are examined, sinus rhythm was observed in 34 (85%) patients in Group I and 50 (84.7%) patients in Group II. There was no statistically significant difference in return to sinus rhythm in the first year (p = 0.975). Conclusions: The success rates of these two methods used in AF surgery are effective but they are not superior to each other.

Introduction: Low hematocrit level is a hematological problem that is frequently encountered in the preoperative evaluation of patients undergoing coronary artery bypass grafting (CABG) surgery. The aim of this study was to investigate the effect of preoperative hematocrit level on the first 30-day outcomes in patients undergoing CABG surgery. Methods: Ninety-four patients undergoing isolated CABG were included in the study. The patients were divided into two groups as patients with preoperative low hematocrit levels (
