Item Cardiovascular Surgeon's Perspective of the Iatrogenic Vascular Injuries in Gynecologic Surgery(2014) Akay, Hakki Tankut; Korun, Oktay; Sezgin, Atilla; Aslamaci, Sait; https://orcid.org/0000-0002-5776-6993; AAJ-1341-2020Background: This study aims to define basic parameters and to propose certain attitudes towards the management of such patients. Methods: Data of the 18 gynecologic surgery patients (mean age 54.4 +/- 3.2 years; range 45 to 63 years) who were intraoperatively consulted to vascular surgery for vascular trauma between January 2003 and December 2012 were retrospectively analyzed. All patients had undergone a previous surgical procedure in the same surgical site. Results: The vascular structures injured were the iliac arteries in eight patients, iliac veins in eight patients and inferior vena cava in two patients. The mean length of intensive care unit and hospital stays were 2.7 +/- 1.2 and 7.1 +/- 1.6 days, respectively. One patient died postoperatively. Conclusion: We believe that favorable results for this potentially lethal complication can be achieved with individual management strategies tailored in accordance with certain principles.Item Evaluation of Safety and Efficacy of Liver Biopsy Following Liver Transplant(2015) Kirnap, Mahir; Akdur, Aydincan; Reyhan, Nihan Haberal; Aytekin, Cuneyt; Harman, Ali; Yildirim, Sedat; Moray, Gokhan; Haberal, Mehmet; 0000-0003-2498-7287; 0000-0001-9852-9911; 0000-0002-3462-7632; 0000-0002-5735-4315; 0000-0002-8726-3369; 0000-0002-7386-7110; 0000-0001-5134-168X; 25894180; AAE-1041-2021; AAK-4587-2021; AAJ-8097-2021; AAF-4610-2019; AAH-9198-2019; AAA-3068-2021; K-9824-2013Objectives: Liver biopsy is a diagnostic tool for liver pathology after liver transplant. However, biopsy can cause life-threating complications. There is limited knowledge about efficacy and complications of liver biopsy after liver transplant. Our aim was to evaluate the risk and benefit of liver biopsy after liver transplant and quality of biopsy specimens. Materials and Methods: We retrospectively analyzed all liver biopsies performed after liver transplant between January 2000 and October 2014. All patients were monitored for minimum 24 hours after biopsy. Results: We performed 245 liver biopsies in 159 liver transplant patients. Fifteen biopsies (6%) were nondiagnostic. In the samples, there were 102 cases (41%) of acute rejection, 79 cases (35%) of cholangitis, and 49 cases (20%) of cholestasis observed. Complications after biopsy were seen in 23 patients (9%) and biopsies. There were 7 patients who had severe abdominal pain followed by fever. We diagnosed 4 patients who had intercostal/subcapsular bleeding and 12 patients who had vasovagal reaction. All patients were treated with analgesic agents and monitored for 24 hours. No blood transfusion or surgery was required. Conclusions: Liver biopsy after liver transplant is an invasive diagnostic tool for liver pathology. However, it can be used safely in experienced centers.Item Fatal Outcome After Renal Transplant in a Pediatric Patient With Noonan Syndrome(2015) Araz, Coskun; Kaval, Ebru; Torgay, Adnan; Moray, Gokhan; Haberal, Mehmet; 0000-0003-2498-7287; 0000-0002-6829-3300; 0000-0002-4927-6660; 0000-0002-3462-7632; 25894171; AAE-1041-2021; AAJ-5221-2021; AAJ-4576-2021; AAJ-8097-2021Noonan syndrome is a congenital, common, hereditary disorder. Facial dysmorphism, growth retardation, and various heart defects are typical clinical features. In patients with minor cardiac pathology, life expectancy is normal. We report a case of renal transplant in a pediatric patient with Noonan syndrome that ended with death of the patient. Our patient presented with unexpected and refractory postoperative neurological complications that were unresponsive to intensive therapy, and the patient died because of secondary complications.Item Diaphragmatic Hernia After Pediatric Liver Transplant(2015) Kirnap, Mahir; Akdur, Aydincan; Ozcay, Figen; Soy, Ebru; Coskun, Mehmet; Moray, Gokhan; Haberal, Mehmet; 0000-0002-3462-7632; 0000-0002-8726-3369; 0000-0003-2498-7287; 0000-0002-5214-516X; 0000-0001-5630-022X; 0000-0002-0993-9917; 26450470; AAJ-8097-2021; AAA-3068-2021; AAE-1041-2021; ABG-5684-2020; AAM-4120-2021; AAC-5566-2019; AAH-9198-2019Diaphragmatic hernia is an unusual complication after pediatric liver transplant. Nearly half of bowel obstruction cases, which require surgical intervention in liver transplant patients, are caused by diaphragmatic hernia. The smaller patients are at risk for higher rates of diaphragmatic complication after pediatric liver transplant, but diaphragmatic hernia has not been reported as a unique occurrence. Here, we report 3 cases of diaphragmatic hernia after liver transplant and discuss the possible contributing factors. Diaphragmatic hernia should nevertheless be added to the list of potential complications after liver transplant in the pediatric population. Pediatric transplant physicians and surgeons should be aware of this complication so that it is recognized promptly in both acute and nonacute settings and appropriate action is taken.Item Comparison of the Early Term Complications and Patency Rates of the Standard (Parachute) and Diamond-Shaped End-To-Side Anastomosis Techniques in Arteriovenous Fistulas Created for Hemodialysis(2018) Yabanoglu, Hakan; Kus, Murat; Arer, Ilker Murat; Bali, Cagla; Avci, Tevfik; Akdur, Aydincan; Caliskan, Kenan; https://orcid.org/0000-0002-1161-3369; https://orcid.org/0000-0001-6529-7579; https://orcid.org/0000-0003-2615-1918; https://orcid.org/0000-0001-5225-959X; https://orcid.org/0000-0002-8726-3369; https://orcid.org/0000-0002-8767-5021; 30060787; AAJ-7865-2021; AAJ-7870-2021; AAI-8790-2021; AAF-1698-2021; AAA-3068-2021; AAJ-7201-2021Objective: To compare the early-term patency and complication rates of the end-to-side anastomosis techniques parachute and diamond-shaped techniques in arteriovenous fistulas. Study Design: Prospective randomised study. Place and Duration of Study: Department of General Surgery, Adana Baskent University Application and Research Hospital, Adana, Turkey, between October 2014 and January 2015. Methodology: Patients with end stage renal disease who underwent arteriovenous fistula creation for hemodialysis were grouped into two according to the anastomosis technique performed. Group 1 was composed of the patients undergoing the standard parachute technique and Group 2 consisted of the patients operated with the diamond-shaped anastomosis technique. The two groups were compared with each other with respect to clinical and demographic data, operative and postoperative variables, and complication and patency rates. Results: A total of 56 patients underwent arteriovenous fistula creation. The overall complication rate was 12.5%. The early-term patency rate was higher in the diamond-shaped anastomosis technique than the standard parachute end-to-side anastomosis technique. Effective dialysis was established after 4 weeks in 48 (85.7%) patients in the overall study group, 23 (82.1%) in Group 1, and 25 (89.2%) in Group 2. However, there was no significant difference between both the techniques with respect to effectiveness of dialysis. Conclusion: Both end-to-side anastomosis techniques have their own advantages and disadvantages. Using a patient-specific suitable technique rather than a standard technique would be more appropriate in arteriovenous fistulas formation.Item Accidental Displacement of Mandibular Third Molar Roots into the Pterygomandibular Space(2018) Tamer, Y.; Pektas, Z. O.; 30074013; AAE-7376-2019The surgical removal of impacted third molars is one of the most common procedures performed in both oral surgery and general dentistry. Accidental displacement of the impacted tooth or root fragments to the adjacent anatomical spaces is a rare but serious complication with even life-threatening complications. This case report presents the diagnosis and surgical management of an accidentally displaced right mandibular third molar root via an intraoral approach.Item Postoperative Pleural Effusions After Orthotopic Heart Transplant: Cause, Clinical Manifestations, and Course(2016) Ulubay, Gaye; Kupeli, Elif; Dedekarginoglu, Balam Er; Bozbas, Serife Savas; Alekberov, Mahal; Sever, Ozlem Salman; Sezgin, Atilla; 0000-0003-2478-9985; 0000-0002-5826-1997; 0000-0002-7230-202X; 27805531; AAB-5064-2021; AAB-5345-2021; AAI-8064-2021Objectives: Postoperative pleural effusions are common in patients who undergo cardiac surgery and orthotopic heart transplant. Postoperative pleural effusions may also occur as postcardiac injury syndrome. Most of these effusions are nonspecific and develop as a harmless complication of the surgical procedure itself and generally have a benign course. Here, we investigated the cause and clinical and laboratory features of postoperative early and late pleural effusions in orthotopic heart transplant patients. Materials and Methods: We retrospectively reviewed the medical records of 50 patients who underwent orthotopic heart transplant between 2004 and 2015 at Baskent University. Patient demographics and clinical and laboratory data, including cause of heart failure, presence of pleural effusions at chest radiography in the first year after transplant, timing of onset, microbiologic and biochemical analyses of pleural effusions, and treatment strategies were noted. Results: Mean age of patients was 39.22 +/- 13.83 years (39 men, 11 women). Reason for heart failure was dilated cardiomyopathy in most patients (76%). Nineteen patients (38%) had postoperative pleural effusions, with 15 patients (78.9%) with pleural effusion during the first week after transplant. Of these, 4 patients had recurrent pleural effusion. A diagnostic thoracentesis was performed in 10 patients, with 4 showing transudative effusion and 6 showing exudative effusion secondary to infection (2 patients), postcardiac injury syndrome (1 patient), and hemo thorax (3 patients). Aspergillus fumigatus was detected by quantitative culture from pleural effusion in 1 patient. Tube thoracoscopy drainage was performed in 10 patients (25%), and 2 patients received antibiotic therapy. Conclusions: Pleural effusions are frequent after cardiac transplant. Complications may occur in a small portion of patients, with most effusions being nonspecific and having a benign course with spontaneous resolution. Early diagnostic thoracentesis could improve post operative outcomes in these patients.Item Polytrauma in the Geriatric Population: Analysis of Outcomes for Surgically Treated Multiple Fractures with a Minimum 2 Years of Follow-Up(2022) Sahin, Orcun; https://orcid.org/0000-0002-6035-6258; 35294739; AAF-4032-2021Introduction This study analyzed the clinical and radiological outcomes of geriatric polytrauma patients who had multiple fractures surgically treated and a minimum of 2 years of follow-up. Methods Eighty-six geriatric patients with polytrauma and multiple fractures which were surgically treated in orthopedics and who had a minimum of 2 years of follow-up were retrospectively analyzed. Patients' demographic characteristics, comorbidities, and follow-up time were recorded. The mechanism of injury, fracture type and location, Injury Severity Score (ISS), American Society of Anesthesiologists (ASA) score, duration of hospital stay, complications, and 1-year mortality were also recorded. Fracture union, implant failure, and refractures/misalignment were analyzed from radiographs. Results There were 34 (39.5%) male and 52 (60.5%) female patients. Mean age was 73.5 years with an average follow-up time of 32.9 months. Patients had more low-energy traumas and more lower extremity, comminuted fractures. On the contrary, high-energy traumas and femur/pelvic fracture surgeries had higher associated mortality. The mean ISS score was 26.3. The most common ASA score was ASA 3 (75.8%). The most common clinical and radiological complications were prolonged wound drainage and implant failure. The total 1-year mortality rate was 22.1%. Patients with high ASA scores and patients with lower extremity fractures (femoral/pelvic fractures) also had significantly increased mortality rates. No significant relation was detected between mortality and ISS, fracture type, number of fractures, and duration of hospital stay. Conclusion Orthopedic surgeons must be alert about the possible complications of femoral fractures and comminuted fractures including pelvic girdle. Surgically treated, multifractured patients with high-energy trauma, advanced age, and high ASA scores are also at risk for mortality regardless of the ISS, comorbidities, and duration of hospital stay. Pulmonary thromboemboli must be kept in mind as a significant complication for mortality.Item The Effect of Smoking on Septoplasty and Septorhinoplasty Outcomes(2022) Erol, Ozan; Koycu, Alper; 0000-0003-1290-3509; 34988636; AAF-3650-2021Background There have been many studies in the literature describing the techniques, the associated comorbidities and the outcomes related to septoplasty and septorhinoplasty, while there have been few studies evaluating the effects of cigarette smoking on septorhinoplasty. The present study evaluates the effect of cigarette smoking on complication and revision rates and compares the functional results of smoking and non-smoking patients. Method The data of 598 patients were retrospectively analyzed, and the age, gender, cigarette smoking status, type of operation, NOSE scores, complications and revision rates were recorded. For the purpose of the study, three different patient groups were defined, being those who had never smoked, those who smoked in the past but had quit and active cigarette smokers. The preoperative and postoperative 6th month Nasal Obstruction Symptom Evaluation (NOSE) Questionnaire scores were compared, and the three groups were compared in terms of complications and the need for revision. Results No differences were identified in the complication rates or revision requirements of the three groups with different cigarette smoking statuses (p=0.17 and p=0.74, respectively). The NOSE scores of the surgery groups and cigarette smoking categories improved significantly after the operation (p=0.01). No difference was identified in the NOSE scores of the groups with different cigarette smoking statuses (p>0.05). Conclusion Active cigarette smoking has no effect on the functional results and rates of complication/revision after septoplasty or septorhinoplasty operation. That said, surgeons should suggest that patients quit smoking preoperatively in order to minimize the general systematic effects of cigarette smoking.Item Effects of Orthopedic Instruments Breakage During Surgery: A Minimum Five-Year Follow-Up(2021) Haberal, Bahtiyar; Beyaz, Salih; 0000-0002-1668-6997; 0000-0002-5788-5116; W-9080-2019; K-8820-2019Aim: The present study aims to investigate the the long-term effect of metallic orthopedic instruments that were broken and not removed during surgery on the health status of patients. Material and Methods: Radiographs of 12,601 patients (5765 females and 6836 males; mean age: 48.9 years; range: 0-105) who underwent orthopedic surgery in our clinic between January 2009 and January 2015 were screened. Thirty-six patients (13 females and 23 males; mean age: 45.3 years; range: 12-82) with metallic instruments, broken and not removed during surgery, were included in the study and minimum five-year follow-up radiographs of the patients were examined. Results: The rate of orthopedic instrument breakage during surgery was 0.28%. This was 0.64% in trauma cases and 0.08% in elective surgery cases. The broken instrument was a Kirschner wire (K-wire) in 16 (44.4%) cases, a screw in 14 (38.9%), and a drill bit in 6 (16.6%). The rate of instrument breakage was 7.44 times higher in trauma cases than in elective surgery cases, which was statistically significant (p = 0.001). Only 1 patient required reoperation for the broken instrument 7 years later. No surgical notes regarding broken implants were identified in patient files. Discussion: Instruments that are broken and not removed during surgery do not cause any complication if they are entirely within the bone. Nevertheless, any instance of instrument breakage should be documented, and the patient should be informed about the condition and followed closely.
