Objectives This study assessed the feasibility and outcomes of performing robotic cardiac surgery without lung isolation using single‐lumen (SL) endotracheal tube intubation. Methods Between 2013 and 2017, 132 patients underwent robotically‐assisted atrial septal defect closure. A retrospective analysis was performed of 23 patients (11 males, mean age 30.9 ± 5 years) who underwent robotic surgery with double‐lumen (DL) endotracheal tube intubation (group 1) compared with 109 patients (57 males, mean age 32.4 ± 7.5 years) undergoing the same procedure with SL endotracheal intubation (group 2). The patient groups were compared in terms of demographic characteristics, operative data, and complications. The technical feasibility of the robotic procedure without lung isolation was evaluated. Results There were no mortality, intraoperative complication, and conversion. Mean total anesthesia time was significantly decreased in the SL intubation group (238.3 ± 22.4 vs 227.2 ± 21.2 minutes; P = .025). First‐pass intubation success was significantly higher in the SL intubation group (17 [73.9%] vs 98 [89.9%] patients; P = .032). Mean ventilation time (10.9 ± 5.3 hours), intensive care unit stay (16.8 ± 10.1 hours), and the length of hospital stay (3.8 ± 1.2 days) was significantly decreased in patients with SL tube (P < .05). Unilateral reexpansion pulmonary edema was observed in five (21.7%) patients with DL tube, whereas no patient with SL tube had this complication. Conclusions SL endotracheal tube intubation without lung isolation is a feasible and safe airway alternative in robotic cardiac procedures. This approach resulted in shorter anesthesia time, ventilation time and the length of hospital stay. Port placement and robotic set‐up can be uneventfully performed without lung isolation.

Aim: The gold standard repair of thoracoabdominal aortic aneurysm (TAAA) is still open surgery. However, few cardiovascular centers are experienced in TAAA repair. The aim of this study was to examine the methods and four-year outcomes of the open TAAA repair program initiated by a single surgical team. Material and Methods: In this retrospective cohort, patients who were operated for TAAA between August 2018 and March 2022 were collected. Patients treated with the endovascular approach were excluded. After exclusion, 19 patients were included in our analysis. As postoperative outcomes, in-hospital mortality, spinal cord deficit, major neurologic complications, need for dialysis, and visceral ischemia were collected. Results: Crawford extent II TAAA repair was performed in 10 (52.6%) patients, Crawford extent III in 5 (26.3%) patients, and Crawford extent IV in 4 (21.1%) patients. In hospital mortality occurred in 6 (31.6%) patients. The causes of mortality were perioperative myocardial infarction in 2 (10.5%) patients, visceral ischemia in 1 (5.3%) patient, multisystem organ failure in 3 (15.8%) patients. The highest mortality rate (50.0%) occurred in Crawford extent II repair. Spinal cord deficit developed in 2 (10.5%) patients. Conclusion: Thoracoabdominal aortic aneurysm surgery is associated with high mortality rates. Open thoracoabdominal aortic aneurysm repair programs in tertiary vascular centers should be supported, to improve the surgical results of thoracoabdominal aortic aneurysm repair.

Introduction Custodiol (histidine-tryptophan-ketoglutarate) and repetitive blood cardioplegia are the solutions for myocardial protection and cardiac arrest. In this study, we aimed to compare immunohistochemical analysis, clinical outcomes, and cardiac enzyme values of Custodiol and blood cardioplegia groups. Methods This was a randomized prospective study consisting of 2 groups and 20 patients, 10 patients for each group, who underwent mitral and mitral/tricuspid valve surgery. Group 1 was formed for Custodiol cardioplegia and group 2 for blood cardioplegia. Perioperative and postoperative cardiac events were recorded, cardiac enzymes were analyzed with intervals, and myocardial samples were taken for immunohistochemical analysis. Recorded data were statistically evaluated. Results There was no significant difference for the Custodiol and blood cardioplegia groups in perioperative and postoperative cardiac performance and adverse events. Cardiac enzyme analysis showed no significant difference between groups. However, two parameters (eNOS, Bcl-2) were in favor of the Custodiol group in immunohistochemical studies. Custodiol performed better in cellular oxidative stress resistance and cellular viability. Conclusion Clinical outcomes and cardiac enzyme analysis results were similar regarding myocardial protection. However, Custodiol performed better in the immunohistochemical analysis.

Aim: Technological developments on endovascular stents have increased the percutaneous repair of abdominal aortic aneurysm(AAAs). Open repair of abdominal aneurysm remains as the first option for treatment of aneurysm with compromising necks that need suprarenal aortic clamping(SAC). Open surgical repair with suprarenal aortic clamping may be associated with renal ischemia that may lead into renal injury. Our study focused on our clinical experience on the use of custodiol solution for renal protection during open repair of abdominal aortic aneurysm with suprarenal aortic clamping. Material and Methods: Our study consisted of 25 patients who underwent open repair for abdominal aortic aneurysm with suprarenal aortic clamping. During the repair, cold custodiol solution was used for renal protection in all patients. Outcomes included postoperative renal functions, mortality, hospital stay, need of postoperative dialysis and readmission due to renal injury. Results: 2 (8%) of our patients died, 2 patients (8%) experienced acute renal injury, hemodialysis was required in 8 patients (32%). There were 3 cases of morbidity, which included ileus in one patient, pneumonia in one patient and wound infection in one patient. Graft interposition was performed in one patient (4%) while aortobifemoral bypass was performed in 24 patients (96%). Conclusion: In our clinical experience, cold custadiol solution has shown to be safe as a renal protective solution during suprarenal aortic clamping in open repair of abdominal aortic aneurysm with well-preserved perioperative renal functions.
