Investigation of the effect of visceral adiposity index on venous clinical severity score in patients with chronic venous insufficiency
Introduction: Chronic venous insufficiency (CVI) is a common disease affecting millions worldwide. Age, obesity, female gender, sedentary life, and long-standing at work causing orthostasis have been identified as predisposing factors. Objective: The visceral adiposity index (VAI) is an important indicator of abdominal obesity. Various studies in the cardiovascular field have shown that it may be more predictive than body mass index (BMI). Methods: A total of 171 consecutive patients diagnosed with low-grade (C0–C3) superficial primary CVI in our clinic, between November 2021 and December 2022, were included in this prospective study. Venous Clinical Severity Score (VCSS) values were calculated. The patients were divided into two groups according to their VCSS values (Group 1: VCSS ≤6 and Group 2: VCSS >6). Results: There were 110 patients in Group 1 with a median age of 42 (18–50) years. There was no difference between the groups in terms of gender, smoking, hypertension frequency, height, weight, body mass index, hemoglobin values, lymphocyte, neutrophil, mean platelet volume, urea, creatinine, high-density lipoprotein, low-density lipoprotein, triglyceride, and total cholesterol values ( p > .05). Multivariate logistic regression analysis was performed to reveal the predictive factors of high VCSS values in patients. As a result of the analysis, VAI (Odds Ratio (OR): 1.775; 95% Confidence Interval (CI): 1.389–2.269; p < .001) and CRP (OR: 2.641; 95% CI: 1.431–4.875; p = .002) values were identified as independent predictors in predicting high VCSS values. Conclusion: This current study showed that high VAI values affect clinical complaints in patients with low-grade CVI. In line with our results, clinical recommendations can be made to reduce VAI values in low-stage CVI patients.

Evaluation of the Effect of Preoperative HbA1c Value on Development of Postoperative Atrial Fibrillation in Diabetic Patients with On-Pump Coronary Artery Bypass Graft.
Background: We aimed to determine the relationship between HbA1c levels and the development of postoperative atrial fibrillation (PoAF) . Methods: 288 patients diagnosed with diabet and undergoing on-pump coronary bypass were included in the study. Those with serum HbA1c levels between 5.5-7.0% were defined as Group 1, those with serum HbA1c levels between 7.1-8.9% were defined as group 2, while those with serum HbA1c levels 9.0% and above formed Group 3. Data between groups were compared. The predictive values of the independent variables for the development of PoAF were measured. Results: We did not found difference between groups in terms of development PoAF (p=0.170). Presence of hypertension was determined as an independent predictor for the development of PoAF (p=0.003) but not HbA1c levels (p=0.134). There was 50.5% sensitivity and 61.1% specificity for HbA1c values of 9.06% and above to predict PoAF (AUC: 0.571, p=0.049) Conclusions: HbA1c levels were not an independent predictor of PoAF development. However, we think that high HbA1c levels may be a risk factor for the development of PoAF.

Use of del Nido Cardioplegia Solution in Adult Aortic Surgery
Background:The aim of the present study was to compare the operative and early postoperative results of the use of del Nido Cardioplegia solution(dNCS) with traditional blood cardioplegia(BC) in adult aortic surgery. Methods: A retrospective single-center study was performed on 118 patients who underwent aortic surgery with cardiopulmonary bypass (CPB) between January 2016 and June 2020. Patients were divided in to two groups according to the type of cardioplegia solution used during the operation. Cardiac arrest was achieved in Group 1(n:65) with traditional BC and in Group 2(n=53) with dNCS. Operative and postoperative outcomes of the patients were compared between the two groups. Results: Patient demographic characteristics were similar between the two groups. dNCS group showed significantly lower aortic cross-clamp (ACC) time(87,5 vs 73,3 min; P=0.001), cardioplegia volume (P<0.001), defibril¬lation(P=0.006), drenaige amount(P=0.026) and inotropic support need (P=0.046).Also dNCS group had significantly lower high sensitive troponin I (hsTnI) values at 6th (P=<0.001) and 24th (P=0.017) hours. Hematocrit levels at hours 6 and 24 were significantly higher in dNCS (P=0.001).Time of intensive care unit stay, duration of extubation and length of hospital stay times were similar in both groups. There was no significant difference in terms of postoperative ejection fraction values(P=0.714). Conclusion: Compared with conventional BC, dNCS provided beter myocardial protection with significantly shorter ACC times, reduced need for intraoperative defibrillation, postoperative lower hsTnI levels and comparable early clinical outcomes for adult patients undergoing aortic surgery. dNCS is a safe and efficient alternative to the traditional BC solution in adult cardiac surgery.

Effect of del nido cardioplegia use on kidney injury after coronary bypass operations
After cardiac surgery, acute kidney injury is observed at a rate of 5-30%, and the second most common cause of acute kidney injury in intensive care units is cardiac surgery. In this study, we aimed to investigate the effect of del Nido cardioplegia solution use on postoperative acute kidney injury development in patients who underwent coronary artery bypass grafting operation with cardiopulmonary bypass. Consecutive patients who underwent an elective coronary artery bypass grafting operation with cardiopulmonary bypass in our clinic between March 15, 2019, and March 15, 2020, were included in the study retrospectively. The patients were divided into two groups as those who received del Nido cardioplegia solution (Group 1) and blood cardioplegia (Group 2), and factors affecting the development of renal failure were examined. A total of 350 consecutive patients were included in the study. There were 156 patients in the del Nido cardioplegia group and 194 patients in the blood cardioplegia group. Among the patient group, 74 (21.1%) patients developed acute kidney injury. The total acute kidney injury development rate was significantly higher in Group 2 (p=0.018). In multivariate logistic regression analysis, advanced age (OR 1.128; 95%CI 1.044-1.217; p=0.042), increased blood product use (OR 1.318; 95%CI 1.154-1.998; p=0.019), preoperative creatinine elevation (OR 2.434; 95%CI 1.655-4.639; p=0.005), and increased cardioplegia volume (OR 1.254; 95%CI 1.109-2.980; p=0.009) were independent predictors of acute kidney injury. With this study, we showed that the use of del Nido cardioplegia solution can reduce the incidence of acute kidney injury.

Early Postoperative Results of On-Pump Coronary Endarterectomy: Is Gender a Risk Factor?
Background: Coronary endarterectomy (CE) combined with coronary artery bypass grafting (CABG) is an effective but still controversial surgical strategy for the treatment of diffuse coronary artery disease. In this study, we aimed to investigate the impact of gender differences on operative and early postoperative results of patients who underwent CABG with CE. Methods: This retrospective study included 141 patients who had undergone CE combined with CABG from January 2015 to December 2020, as well as 141 patients without CE as the control group. First, patients with and without CE were compared. Next, patients undergoing CE were divided into 2 groups according to gender (group 1, male patients; group 2, female patients). Results: Of the 141 patients who underwent CE combined with on-pump CABG, 95 (67.3%) were male, and median age was 66 years (range 58 to 71.2). Of the 141 patients who underwent isolated on-pump CABG, 99 (70.2%) were males, and median age was 63 years (range 41 to 80.4). The data for these 2 groups (with and without CE) were compared. Previous percutaneous coronary intervention (PCI), presence of diabetes mellitus, and perfusion time were significantly more common in the CE group. There were 95 patients in group 1, with a median age of 65 years (range 58 to 69), and 46 patients in group 2, with a median age of 66 (64 to 71.2). There were no difference between the groups in terms of age, body mass index, hyperlipidemia, chronic obstructive pulmonary disease, peripheral artery disease, or previous coronary intervention. The need for positive inotropic support and postoperative atrial fibrillation were found to be significantly more common in group 2 (P = .022 and .039, respectively). Defibrillation after releasing the aortic cross clamp was also significantly more common in group 2 (P = .025). Conclusion: In our study, the need for defibrillation after aortic cross-clamp releasing in the perioperative period, the need for inotropic support and the incidence of atrial fibrillation in the post-operative period, increased significantly in the female gender. CE can be performed safely in both genders with acceptable mortality and morbidity rates.

Intraoperative Hyperoxygenation May Negatively Affect Postoperative Cognitive Functions in Coronary Artery Bypass Graft Operations: A Randomized Controlled Study
Objective: In this study, it was aimed to compare various parameters during surgery and postoperative cognitive functions in patients undergoing coronary artery bypass graft (CABG) surgery using different levels of perioperative oxygen. Methods: One hundred patients scheduled for elective CABG surgery were included in the study. The patients were divided into two groups according to arterial oxygen levels during surgery. In the normoxia group (NG) (n = 50), PaO2 was between ≥100mmHg and <180mmHg with at least 40% FiO2 mechanical ventilation (MV), and in the hyperoxia group (HG) (n = 50), PaO2 was ≥180 mmHg with 100% FiO2 MV. Hemodynamic parameters, peripheral oxygen saturation (SpO2), cerebral oxygen saturation (rSO2) measured from bilateral sensors, and blood gas values were recorded at the planned measurement times. Mini-mental state examination test (MMSE) was applied to the patients before and at the 12th, 24th hours; on the 1st, 3rd, 6th months after surgery. Results: Extubation time was found to be shorter in NG (p <0.05). Between the groups, rSO2 and mean arterial pressure (MAP) were found to be significantly lower in HG at the time of T4 measurement (p = 0.042, p = 0.038, respectively). MMSE values of the groups at the 1st, 3rd and 6th months were found to be significantly higher in NG (respectively p = 0.017, p = 0.014, p = 0.002). Conclusion: Hyperoxemia application during CABG may be associated with worse postoperative late-term cognitive functions. Keywords: cardiopulmonary bypass; hyperoxia; postoperative complications; cognitive function; spectroscopy, near-infrared.
