Clinical outcome of patients in a start-up congenital heart surgery program in Turkey.

This study summarizes the clinical outcome data of a start-up congenital heart surgery program in Turkey. Between December 2009 and February 2012, 616 operations have been performed in 132 newborns (22%), 260 infants (42%), and 224 children/adolescents (36%). Risk adjustment analysis was performed using the risk adjustment in congenital heart surgery (RACHS-1) risk assessment model. There were 66 mortalities (10.7%). According to the RACHS-1 categories, there were 51 cases in level I (8.2%) with no mortality (0%), 250 in level II (40.6%) with 11 (4.4%) mortalities, 199 in level III (32.3%) with 33 (16.5%) mortalities, 53 in level IV (8.6%) with 10 (18.8%) mortalities, 14 in level V and VI (2.2%) with 11 (78.5%) mortalities, and 49 cases (7.9%) out of the RACHS-1 categories with one (2.0%) mortality. Mortality was higher in neonates compared to infants, and in infants compared to children/adolescents. Mortality was higher in palliative procedures compared to corrective procedures. The data demonstrate that a start-up program with a relatively loaded surgical volume may achieve acceptable clinical results with a good teamwork. Collaboration of anesthesiologists, perfusionists, pediatric cardiologists, intensivists, and cardiovascular surgeons is necessary to provide a better outcome in congenital heart surgery.

Extracorporeal life support experiences of a new congenital heart center in Turkey.

Extracorporeal life support (ECLS) provides mechanical support following cardiac surgery when respiratory and cardiac failure occurs. We retrospectively reviewed medical records of patients who needed ECLS at a new congenital heart center in Turkey. Between December 2009 and February 2012, 616 congenital heart operations were performed. A total of 13 patients (seven female) underwent ECLS. The ages of the patients ranged between 16 days and 33 years. There were two neonatal, seven infant, three pediatric, and one adult congenital cases. Medos DPII ECLS system was used in all patients. Mean duration of ECLS was 6.2 ± 5.8 days (ranged from 29 h to 24 days). While central vascular access with aorta and right atrial cannulation was used in 11 patients, neck vessels were used in the other patients. Four patients (30.7%) weaned successfully from ECLS (two infant, two pediatric cases). Three of them had ECLS intraoperatively. In all patients, two (15.4%) were discharged from the hospital. One of them had mild neurologic deficit. Bleeding from the surgical and cannulation sites was the most common complication. Thrombus was detected in pump head and changed uneventfully in three patients. Arterial pH and lactate levels at the beginning of ECLS were significantly lower in patients who were successfully weaned from ECLS than nonsurvivors (P = 0.04 and P = 0.02, respectively). ECLS can be a lifesaving modality in the perioperative period. It may be more beneficial if ECLS is used before the development of severe acidosis and high lactate levels.

Preoperative Anemia and Female Gender are Risk Factors for Transfusion in Patients Undergoing Coronary Artery Bypass Grafting with a Restrictive Transfusion Strategy.

Objective: Red blood cell (RBC) transfusion in cardiac surgery is associated with increased morbidity and mortality. Even when using patient blood management methods, blood transfusions may still be needed in cardiac surgery. This study examined the risk factors for blood transfusion in isolated coronary artery bypass graft (CABG) surgery with a restrictive transfusion strategy, along with individualized patient blood management. Methods: We enrolled 198 patients (age, 61.8 ± 9.9 years; 28 females and 170 males) who underwent isolated CABG surgery in a single private hospital using a restrictive transfusion strategy between April 2015 and October 2020. Pre-, intra-, and postoperative parameters were compared between patients with and without RBC transfusions. The risk factors for transfusion and transfusion probability were analyzed. Results: Patients who received RBC transfusions had higher European System for Cardiac Operative Risk Evaluation values (13.60 ± 18.27%). Preoperative hematocrit (Hct) [odds ratio (OR)=0.752; 95% confidence interval (CI) 0.639-0.884; P=0.001] and female gender (OR=7.874; 95% CI 1.678-36.950; P=0.009) were significant independent risk factors for RBC transfusion in logistic regression analysis. When the preoperative Hct was 30%, the RBC transfusion probability was 61.08% in females and 16.6% in males. Patients who received RBC transfusions had longer intensive care unit (31.40 ± 25.42 hours) and hospital (11.18 ± 6.75 days) stays. Conclusion: Risk factors for RBC transfusion in isolated CABG surgery with a restrictive blood transfusion strategy were preoperative anemia and female gender.

Postoperative Atrial Fibrillation Reduced by Intraoperative and Postoperative Cell Saver System in Coronary Artery Bypass Graft Surgery.

OBJECTIVE: Postoperative atrial fibrillation is commonly seen after cardiac surgery. One of the contributing factors is mediastinal shed blood and inflammation. Cell salvage techniques can reduce allogenic blood transfusion and reduce inflammation. The aim of this study was to investigate the reduction of postoperative atrial fibrillation by using the cell-salvage system. METHODS: Patients who underwent isolated coronary artery bypass graft surgery (n = 498) were analyzed retrospectively in 2 groups. Postoperative atrial fibrillation group (n = 75) and non-postoperative atrial fibrillation group (n = 423). Preoperative and postoperative demographic and clini- cal data were compared between the 2 groups, respectively. Postoperative atrial fibrillation and possible contributing factors were analyzed with multinomial logistic regression analysis. RESULTS: In the postoperative atrial fibrillation group, the patients' age and European System for Cardiac Operative Risk Evaluation (Euroscore) were higher than in the non-postoperative atrial fibrillation group (P = .001 and P = .003, respectively). Postoperative intensive care unit stay and hospital stay were longer in the postoperative atrial fibrillation group than in the non-postoperative atrial fibrillation group (P = .001 and P = .046, respectively). There were no statistical differences in mortality between groups. The incidence of postoperative atrial fibrillation decreased with the use of cell saver system and low Euroscore. CONCLUSION: The use of a cell salvage device intraoperatively and during the early postoperative period can decrease the incidence of postop- erative atrial fibrillation group.

A rare anatomic variation: a combination of anomalous origin of the right subclavian artery from the main pulmonary artery, ventricular septal defect, and aortic coarctation.

BACKGROUND: We present a rare case of an anomalous origin of the right subclavian artery (SA) from the pulmonary artery (PA) associated with ventricular septal defect (VSD) and aortic coarctation. CASE REPORT: Critical aortic coarctation and VSD were diagnosed in a neonate, and coarctation angioplasty was successfully performed. Severe cardiac failure developed after this procedure, however, and closure of the VSD was planned. RESULTS: The anomalous SA was diagnosed during the operation when the cardiopulmonary bypass was initiated. As the pulmonary blood flow decreased, a difference in pulse pressures between the right radial artery and the ascending aorta was noticed to be due to the subclavian steal phenomenon. The difference decreased from 60 mm Hg to 25 mm Hg following ligation of the SA at its origin from the PA. The patient was discharged on the eighth postoperative day without any problems. CONCLUSION: An abnormal origin of the right SA from the main PA associated with VSD and aortic coarctation is a unique combination that, if unnoticed preoperatively, may create difficulties during the operation.

Transforaminal epidural steroid injection via a preganglionic approach for lumbar spinal stenosis and lumbar discogenic pain with radiculopathy.

BACKGROUND: Epidural steroid injection (ESIs) is one of the treatment modalities for chronic low back pain (CLBP) with various degrees of success. AIM: We analyzed the efficacy of fluoroscopically guided transforaminal epidural steroid injections (TFESIs) via a preganglionic approach in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy. MATERIALS AND METHODS: We analyzed the data of 40 patients (February 2008 and April 2009) with the diagnosis of CLBP and treated by fluoroscopically guided TFESIs via a preganglionic approach. Patients were followed-up at one month (short term), six months (midterm) and one year (long term) after injections. Follow-up data collection included the Visual Numeric Pain Scale (VNS) and North American Spine Society (NASS) patient satisfaction scores. RESULTS: The mean age of the patients was 59.87 +/- 15.06 years (range 30 - 89 years, 25 women). Average follow-up period was 9.22 +/- 3.56 months. Statistically significant differences were observed between the pre-procedure and post-procedure VNSs (P < 0.01, Pearson Correlation Test). Improvements in VNS scores were correlated with improvements in the NASS scores. When the VNS scores were evaluated with respect to the age of patient, level numbers, gender, pre-procedure symptom duration and pre-procedure VNS, no significant differences were found (P < 0.05, linear regression test). At short term evaluation in post treatment (one month), 77.78 % of patients were found to have a successful outcome and 22.22 % were deemed failures. Overall patient satisfaction was 67.23 % in the midterm period. Additionally, 54.83 % of patients (N/n: 15/8) had a successful long-term outcome at a follow-up of one year. CONCLUSION: Our data suggest that fluoroscopically guided TFESIs via a preganglionic approach, in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy, has effective outcome and patients responding to injection have significantly lower post-injection pain scores.

Effect of Alprazolam on Redox Status in Renal Transplantation Donors and Recipients.

BACKGROUND Benzodiazepines are the most popular premedication drugs thought to act through the GABA/benzodiazepine receptor complex and alprazolam is one of the most potent benzodiazepines that have a quick onset. While there is a growing body of evidence supporting alprazolam in the amelioration of redox status in animals, no study has been performed concerning its antioxidant activity in humans. The purpose of this investigation was to determine the effect of alprazolam on redox status. MATERIAL AND METHODS This study was a four-group randomized controlled trial. Participants were recruited from Acibadem University Acibadem International Hospital and included a convenience sample of 82 donors and recipients undergoing renal transplantation. Patients were randomly divided into four groups. While donors and recipients in experimental groups (G1 and G3) were administered alprazolam 0.5 mg orally one hour before the operation, those in control groups (G2 and G4) were not. Serum advanced oxidative protein products, total thiol, free hemoglobin, ischemic modified albumin, and sialic acid levels at different time points were measured to evaluate the redox status. RESULTS All oxidative stress parameters were higher in the alprazolam premedication groups (G1, G3) at all time points than in the control groups (G2, G4). Basal values of oxidative parameters (at time point T1) in patients with CKD (G3, G4) were lower than in healthy donors (G1, G2). CONCLUSIONS Alprazolam premedication in donors and end-stage renal failure patients undergoing renal transplantation does not improve redox homeostasis but further experimental studies are needed.

Complete atrioventricular septal defect and pulmonary stenosis diagnosed in a 49-year-old woman after 10 uneventful births.

Atrioventricular septal defects constitute 4% of all congenital cardiac malformations. Patients with complete atrioventricular septal defect rarely survive for decades without surgical treatment. Pulmonary stenosis can provide a delicate balance between the pulmonary and systemic circulations and thereby increase longevity. We present the case of a 49-year-old woman whose complete atrioventricular septal defect and associated pulmonary stenosis were diagnosed only after she had given birth to 10 live children through uneventful spontaneous delivery. We discuss her successful surgical treatment in terms of the available medical literature.

Twisted wire stent technique for delayed sternal closure after congenital heart operations.

After congenital heart operations, keeping the sternal edges wide open may require sternal stenting in some extreme cases in which delayed sternal closure is necessary after operation, because sternal edges may compromise cardiac function as a result of the elasticity of the thoracic cage. We describe an easy and safe way for sternal stenting using conventional sternal steel wires.
