RESUMEN
INTRODUCTION: In this study we used N-butyl-2 cyanoacrylate (NBCA), including dimethyl sulfoxide (DMSO), via the endovenous route, for mechanochemical ablation in the treatment of superficial venous insufficiency, in an attempt to establish whether an early systemic inflammatory response and an allergic reaction occurred in the patients. METHODS: A total of 102 patients were treated with endovenous medical ablation in two centres between October 2015 and February 2016. This study was a two-centre, retrospective, non-randomised investigational study. Ablation treatment with endovenous NBCA was used in patients with C3 to C4b grade superficial venous insufficiency, according to the CEAP (clinical, aetiology, anatomy and pathophysiology) clinical classification, with sapheno-femoral junctional insufficiency and a reflux of 0.5 seconds and longer on duplex ultra-sonography. Pre-operative whole blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level and blood chemistry were studied in all patients on admission to the clinic, and repeated in the second hour post-intervention. RESULTS: All patients were treated successfully. Pre-operative white blood cell count (WBC) was 6.82 ± 1.67 × 109 cells/µl, and post intervention it was 6.57 ± 1.49 × 109 cells/µl; the difference was not statistically significant (p = 0.68). The neutrophil count before the intervention was 4.09 ± 1.33 × 109 cells/µl, while afterwards, it was 4.09 ± 1.33 × 109 cells/µl, with no statistically significant difference (p = 0.833). Pre-intervention eosinophil count was 0.64 ± 1.51 × 109 cells/µl, while it was 0.76 ± 1.65 × 109 cells/µl after the intervention, and the difference was statistically significant. Pre-intervention ESR and CRP values were 18.92 ± 9.77 mm/h and 1.71 ± 1.54 mg/dl, respectively. Postoperative ESR and CRP values were 19.78 ± 15.90 mm/h and 1.73 ± 1.59 mg/dl, respectively, but the differences were not statistically significant. When the parameters were analysed by gender, the differences between pre- and postoperative WBC and eosinophil count, ESR and CRP in women were not statistically significant. On the other hand, although the change in WBC count and CRP value were not statistically significant in males, the differences in eosinophil count and ESR were statistically significant. CONCLUSIONS: Cyanoacrylate has been used in the endovenous medical ablation of varicose veins and superficial venous insufficiency over the last few years without the use of thermal energy and tumescent anaesthesia, which represents the greatest advantage of this method. In addition, since it causes no systemic allergic or acute inflammatory reaction, it appears to be safe to use.

OBJECTIVE: Coronary artery bypass graft surgery in one of the most effective and widely used methods employed in the treatment of ischemic heart disease, but many factors to various degrees are directly associated with perioperative and postoperative problems. In this study, we evaluated the relationship between preoperative eosinophil count and postoperative mortality in patients who underwent coronary artery bypass graft operation. METHODS: A total of 241 patients (157 males, 84 females) who underwent isolated on-pump coronary artery bypass graft operation between 2011 and 2013 in two centers were evaluated retrospectively. The mean age of patients was 64 ± 11 years. After the mean 6.2 ± 0.8 month follow-up period, 36 (15%) of the 241 patients experienced cardiovascular death. Patients were classified into two groups as those who survived versus those who died. RESULTS: Eosinophil levels were lower among the patients who died compared to the patients who survived (0.8 [0-3.8] versus 1.7 [0-9.4] ×1000 cells/mm3; P < .001). Optimal cut-off level of eosinophils for predicting mortality was determined as ≤1.6 ×1000 cells/mm3, with a sensitivity of 85.7% and specificity of 51.0% (area under curve, 0.703; 95% CI, 0.641-0.760). CONCLUSION: Eosinopenia was used as the predictor of mortality in pediatric and adult patients in the intensive care units. Eosinopenia after coronary artery bypass graft can be related to the endogenous stress hormones, and insufficiency of the existing cardiac status. Eosinophil levels can assist and facilitate risk stratification for patients with coronary artery bypass graft.
