Introduction: The thymus slowly involutes with age after puberty. Various stress conditions accelerate the involution of the thymus and cause changes in the histologic structure of the gland. Objective: The present study performed histomorphological and immunohistochemical (IHC) evaluations of the thymus glands removed during surgical repair in patients with cyanotic or acyanotic congenital heart disease (CHD). The thymus glands in the hypoxic group were compared to those in the non-hypoxic group. This study suggested that the activation of HIF-1 alpha promotes tumor progression and impair prognosis due to the inhibition of apoptosis, increased population of stem cells, and induction of angiogenesis also suggested that inactivation of HIF-1 alpha in tumor-infiltrated tissues could halt tumor progression and improve prognosis. Materials and methods: The study included 76 thymus glands removed from patients who underwent an operation due to CHD. Of these cases, 38 had cyanotic CHD, and constituted the hypoxic group. The remaining 38 patients had acyanotic CHD, and constituted the non-hypoxic group. IHC procedures were performed for HIF-1 alpha, FoxP3, CD44, Bcl-2, and CD34. Results: There were statistically significant differences between the hypoxic and non-hypoxic groups only in terms of medullary enlargement toward the cortex and effacement of the corticomedullary junction. In the immunohistochemical examination for five markers, staining intensity and staining rates increased with decreasing oxygen saturation. Conclusion: It can be concluded that the activation of HIF-1 alpha promotes tumor progression and impair prognosis due to the inhibition of apoptosis, increased population of stem cells, and induction of angiogenesis.

GLOBULINS , *ALBUMINS , *SERUM albumin , *MORTALITY , *DISEASES - Abstract
Objective: Assessment of the albumin, globulin score and albumin to globulin ratio (AGR) as a predictor of mortality and morbidity in patients who underwent Fontan procedure. Method: In a retrospective study, we evaluated serum albumin, globulin concentrations, and albumin- globulin ratio of 56 children who underwent Fontan procedure. Patients divided into two groups. Group 1 consisted of 44 patients who were discharged, and Group 2 consisted of 12 patients who died after surgery. Patients' preoperative and postoperative serum albumin, globulin and albumin globulin rates (AGR) were measured. Receiver-operating characteristic (ROC) curve analysis was used to determine the optimum cut-off levels of the postoperative albumin and AGR to predict mortality. Results: Twelve patients exited soon after surgeries. Postoperative albumin, and globulin values did not differ between groups, however postoperative labumin, and albumin/globulin ratios differed significantly between groups (p=0.002, and p=0.03, respectively). Cut-off value of 3,46 for postoperative albumin became an independent predictor of mortality, with 79% sensitivity, and 83% specificity. A cut-off value of 1.67 became an independent predictor for AGR with 75% sensitivity, and 89% specificity. Postoperative albumin levels below 3.46 mg/dL were associated with 11 -fold increase in the risk of mortality (OR 11; % 95CI 0,27-1,10; p=0.002). Conclusion: Postoperative albumin and AGR are a convenient and effective tool to predict the overall mortality and morbidity in patients undergoing Fontan operations. [ABSTRACT FROM AUTHOR]

Amaç: Bu çalışmada koroner arter bypass cerrahisi planlanan sigara içen hastalarda desfluranın solunum mekaniklerine etkisi araştırıldı. Metod: Randomize, kontrollü, prospektif olarak elektif koroner arter bypass cerrahisi planlanan ASA II-III grubu, 30–80 yaş arası hastalar sigara içen ve kontrol grubu olarak iki gruba ayrıldı. İntravenöz anestezi indüksiyonundan sonra FiO2 % 60 – 80 oksijen ve kuru hava karışımı içine 1 MAC (% 6) desfluran başlandı. Kardiyopulmoner bypass dönemi hariç operasyon süresince desflurana devam edildi. İki grubun kalp atım hızı (KAH), ortalama arter basıncı (OAB), periferik oksijen satürasyonu (SpO2), endtidal CO2 (Et CO2) değerleri ve solunum mekaniği parametreleri ((havayolu direnci (Paw), dinamik kompliyans (Cdyn), tepe hava yolu basıncı (PIP)) entübasyon sonrası (başlangıç) desfluran solumaya başlandıktan sonra 5. ve 20. dakika, sternum açılma, sternum kapama 0., 5. ve 20. dakikalarda kaydedildi. Bulgular: Her iki grup arasında tüm dönemlerde KAH, OAB, SpO2, EtCO2, Paw, Cdyn, PIP değerleri benzer bulundu (p>0.05). Sonuç: İki grup arasında anlamlı bir fark bulunmaması; sigara içen hastaların preoperatif solunum fonksiyon testlerinin normal sınırlarda olmasına bağlı olabilir., This study was planned coronary artery bypass graft surgery in patients who smoke to investigate the effect of desflurane respiratory mechanics Method: ASA II-III group, undergoing coronary artery bypass surgery were classified as smokers and non-smokers. After induction of intravenous anesthesia, FiO2 60 - 80% of dry air into a mixture of oxygen and 1 MAC (6%) desflurane was started. Desflurana except for the period of cardiopulmonary bypass was continued during the operation.Two groups, heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), end-tidal CO2 (Et CO2) and respiratory mechanics parameters (airway resistance (Paw), dynamic compliance (Cdyn), peak airway pressure (PIP)) after intubation (baseline) after the initiation of breathing desflurane 5th and 20th minutes, opening the sternum, sternal closure at 0, 5th and 20th minutes were compared. Results: All measurement periods HR, MAP, EtCO2, SpO2, PIP, Paw, Cdyn values were not significantly different between the two groups. Conclusions: Similar effects are seen in both groups. It may be due to smokers in the study having normal preoperative pulmonary function tests.

Koroner arter bypass greft operasyonlarında intratekal morfin uygulamasının cerrahi travmaya stres, hemodinamik yanıt ve postoperatif ağrı üzerine etkileri değerlendirildi. Prospektif, randomize bu çalışmaya etik komite izni ve hastaların bilgilendirilmiş onayı alındıktan sonra, ASA II-III grubu, elektif koroner arter cerrahisi planlanan, 35-70 yaş arası 40 hasta dahil edildi. Operasyon odasında L2-3 aralığından intratekal yolla Grup ITM'ye 20 mcg kg-1 morfin verildi. Grup K'ya hiçbir şey uygulanmadı. Tüm hastalara standart genel anestezi, cerrahi ve kardiyopulmoner bypass teknikleri uygulandı. Operasyon süresince kullanılan toplam fentanil miktarı kaydedildi. Ortalama arter basıncı, kalp hızı, SpO2 değerleri ile plazma kortizol düzeyleri; anestezi indüksiyon öncesi, sternotomi sonrası, KPB ilk 5. dakika, AKK sırasında, KPB ısınma sonu, hastanın (YBÜ) transferinden sonra, postoperatif 8. saat, postoperatif 1. gün olmak üzere kaydedildi. Hastalara postoperatif dönemde hasta kontrollü anestezi (HKA) cihazı takıldı. Ekstübasyon sonrası 0-6, 6-12, 12- 24, 24-48. saatlerde kümülatif morfin miktarları kaydedildi. Hastaların ağrı düzeyi; ekstübasyondan hemen sonra ve ekstübasyon sonrası 6, 12, 24, 36, 48. saatlerde Vizüel anolog skala (VAS) ile değerlendirildi. İstatistiksel değerlendirmede; t- Student testi; Ki-kare testi kullanıldı. Demografik, intraoperatif ve hemodinamik veriler, postoperatif ekstübasyon süreleri, postoperatif komplikasyonlar açısından iki grup benzer bulundu. Operasyon süresince kullanılan fentanil miktarı Grup ITM'de Grup K'ya göre daha düşük bulundu. Postoperatif kümülatif morfin tüketimi ITM Grubunda K Grubuna göre anlamlı olarak düşük bulundu. YBÜ'e transferden sonra, postoperatif 8. saat ve postoperatif 1.gün alınan kan örneklerindeki serum kortizol düzeyleri Grup ITM'de K Grubuna göre anlamlı olarak düşük saptandı. Öksürme halindeki VAS değerleri Grup ITM'de Grup K'a göre ekstübasyon sonrası, ekstübasyondan sonra 6, 12, 24 ve 36. saatlerde anlamlı olarak düşük bulundu. (p, Aim: The effects of intrathecal morphine application upon surgical insult stress, hemodynamic response and postoperative pain in the operations of coronary arterial bypass graft have been evaluated. Material and Method: After getting permission of ethics committee and informed consent of patients,a prospective randomized study was planned. A total of 40 patients (age range: 35-70 years) of whom elective coronary artery surgery (ASA II-III groups), have been planned were included into the study. In the operating room, 20 mcg kg-1 morphine has been given to Group ITM within the range of L2-3 by the way of intrathecal. Group “K” received no treatment. Standard general anesthesia, surgical and cardiopulmonary bypass techniques have been applied to all patients. Total amount of fentanyl, used during the operation, has been recorded. The average of blood pressure, heart rate, SpO2 values and the levels of blood plasma cortisol; before induction, after sternotomy, at the initial 5 minutes of CPB during AKK, at the end of CPB warm up, after transfering the patient to Intensive Care Unit (ICU) at postoperative 8th hour and postoperative 1st day have been recorded. Patient controlled anesthesia device has been mounted to patients during the postoperative period. After extubation, cumulative morphine portions have been recorded at 0-6, 6-12, 12-24, 24-48. hours. Soon after extubation and at 6, 12, 24, 36, 48. hours after etubation; pain levels of patients have been evaluated with Visual Analogue Scale (VAS). At statistical evaluation; t-Student test; chi square test has been used. Results: Demographic, intraoperative and hemodynamic parameters, postoperative extubation terms have been found similar in the way of postoperative complications in two groups. Fentanyl dosage, used during the operation, has been found lower in group ITM compared to group K. In group ITM, consumption of postoperative cumulative morphine has been found significuntly low compared to group K. Following the transfer to ICU, serum cortisol levels, in the blood samples drawn at postoperative 8th hour and postoperative 1st day, have been detected superior in ITM group to at group K. Shortly after extubation and at 6, 12, 24, 36 hours after extubation, VAS values during coughing have been detected significantly lower in group ITM compared to group K. (p

Amaç: Bu çalışmada, Kardiyovasküler hastalık potansiyeli taşıyan periferik arter hastalarının spinal anestezisinde %0,5 bupivikain ve %0,5 levobupivakain'in anestezik ve hemodinamik parametreler yönünden karşılaştırılması amaçlandı. Yöntemler: ASA II-III grubu 40 hasta randomize olarak 2 gruba ayrıldı; Grup B'de 3.5 mL %0,5'lik bupivakain, Grup L'de 3.5 mL %0.5'lik levobupivakain intratekal yoldan uygulandı. Sempatik blok soğuk sprey, duyusal blok düzeyi pinprick test ve motor blok derecesi Bromage skala ile değerlendirildi. Motor blok, sempatik blok ve duyusal blok başlama, üst segment yükselme süreleri kaydedildi. Duyusal bloğun en üst segmentten iki segment gerilemesi iki segment gerileme süresi, motor bloğun bir derece azalması bloğun geri dönüş zamanı, Bromega skala 0 motor blok kalkma zamanı olarak kaydedildi. Ortalama arter basıncı (OAB), kalp atım hızı (KAH) ve periferik oksijen satürasyonu (SpO2) değerleri spinal anestezi öncesi ölçülerek başlangıç değerleri olarak kabul edildi ve işlem sonrası 1, 5, 10, 15, 20, 30, 45, ve 60. dakikalarda değerlendirildi. Postoperatif ağrı düzeyleri vizüel anolog skala (VAS) ile değerlendirildi. Bulgular: İstatistiksel Değerlendirmelerde, gruplar arasında demografik özellikler, SpO2, VAS değerleri benzer bulundu. OAB ve KAH'nın; başlangıç değerine göre tüm ölçüm zamanlarında her iki grupta da anlamlı olarak azaldığı, ancak gruplar arasında bir fark olmadığı saptandı (p>0,05). Sempatik, duyusal ve motor blok başlama, üst dermatomlara ulaşma, motor blok gerileme ve motor blok kalkma süreleri iki gruptada benzer bulundu (p>0,05). İki segment gerileme süresi grup B'deki olgularda grup L'e göre ileri düzeyde anlamlı olarak düşük saptandı (p, Objective: In this study, it is aimed to compare 0,5% bupivacain and 0,5% levobupivacain in spinal anesthesia for the peripheral arterial disease patients who have a probability of cardiovascular diseases in terms of anesthetic and hemodynamic parameters. Methods: 40 patients in ASA class II or III are randomly separated into 2 groups; in Group B 3,5 ml of bupivacain and in Group L 3,5 ml of levobupivacain have injected intrathecally. Symphatetic blockage is evaluated by cold spray, sensorial blockage is evaluated by pinprick test and the motor blockage is evaluated by Bromage Scale. The beginning and the ascencion to a higher level times of the motor, sympathetic and the sensorial blockages are noted down. 2 levels of regression from the highest level of the sensorial blokcage time is noted as the “2 levels regression time”, 1 grade decrease of the motor blockage time is noted as the “reversion of the motor blockage” and Bromage Scale grade 0 time is noted as the “end of the motor blockage time”. Mean arterial pressure (MAP), heart rate (HR) and peripheral oxygen saturation (SpO2) values are measured before the spinal anesthesia and noted as the beginning values and datas at 1, 5, 10, 15, 20, 30, 45 and 60 minutes after the spinal anesthesia are noted. Postoperative pain levels are evaluated with visual analog scale (VAS). Results: Statistical evaluations of the demographic characteristics, SpO2 and VAS values between the two groups are found similar. MAP and HR are found statistically significantly lower in all of the measurement times in both groups but there is no statistically difference between the two groups (p>0,05). The times of the beginning and the reach to the higher dermatomes of the sympathetic, sensorial and motor blockages, decrease and the end times of the motor blockage are found similar in both groups (p>0,05). 2 levels regression times in Group B are found extremely lower than Grop L (p

Çok kesitli bilgisayarlı tomografi koroner anjiografi ,midazolam ,esmolol ,hidroksizin ,kalp hızı - Abstract
Amaç: Çok-Kesitli Bilgisayarlı Tomografi taraması koroner arter anatomisini incelemede yüksek doğrulukta bilgi veren noninvaziv tanısal bir tetkiktir. Günümüzde beta bloker ilaçlar; işlem öncesinde rutin medikasyon uygulaması halini almıştır. Çalışmamızda, Kartal Koşuyolu Y.İ.E.A.Hastanesi Radyoloji Bölümünde Çok kesitli bilgisayarlı tomografi koroner anjiografi (ÇKBTKA) görüntülemesi yapılacak ASA I ve II grubundaki hastalarda; sedatif, anksiyolitik etkinlikleri bulunan midazolam ve hidroksizinin kısa etkili beta bloker olan esmololle beraber işlem öncesi kullanımının hedef kalp hızına ulaşılmasındaki etklinliğini ve güvenilirliğini araştırmak amaçlandı. Gereç ve Yöntem: Hastanemiz radyoloji bölümüne, BTKA görüntülenmesi amacıyla yönlendirilmiş ve kalp hızı 70 vuru/dk’ nın üzerinde olan 63 hastaya çalışmamız anlatı larak yazılı onamları alındı. Hastalar rastgele üç gruba ayrı ldı, görüntüleme öncesi hazırlanma odasında Beck Anksiyete Ölçeği ile değerlendirildi, işlem öncesi kan basınçları, kalp hızları kaydedildi ve damar yolları açıldı. M grubuna görüntülemeden 10 dakika önce Midazolam 0.05 mgr/kg İV yoldan verildi. H grubuna görüntülemeden yarım saat önce Hidroksizin 1 mgr/kg oral yoldan verildi. Kontrol grubuna ise sedatif anksiyolitik uygulanmadı. ÇKBTKA görüntüleme odasına alınan hastaların kalp hızları tekrar değerlendirildi. Kalp hızları 70-80 vuru/ dk olanlara Esmolol 1 mgr/kg’dan, kalp hızları 80-90 vuru/ dk olanlara Esmolol 2 mgr/kg’dan IV olarak uygulandı. 2 dakika sonra hedef kalp hızına ulaşılamayan olgulara Esmolol 1 mg /kg IV ek doz uygulandı. Geliş kalp hızı 90 vuru/dk’nın üzerinde olan hastalar çalışma dışı bırakıldı. İşlem sırasında sedasyon derinliği Ramsey Sedasyon Skalası kullanılarak değerlendirildi. Her grup için görüntüleme öncesi, görüntüleme esnası, görüntüleme sonrası üç dönemde kan basıncı, kalp hızı, periferik oksijen saturasyon değerleri, toplam kullanılan esmolol dozu, komplikasyonlar (hipotansiyon, bradikardi, hipoksi) kaydedildi. İşlem sonrasında tüm hastalar anestezist tarafından değerlendirilip Modifiye Aldrete Skorlaması 10 puan üzerinde olunca taburcu edildi. Bulgular: Üç grup arasında demografik özellikler açı- sından anlamlı bir fark yoktu (p>0,05). Hidroksizin uygulanan grupta midazolam uygulanan gruba göre daha fazla hastada hedef kalp hızına ulaşılmış ve esmolol ihtiyacı daha az bulunmuştur (p, Objective: Multi-slice computed tomography is a highly accurate non-invasive diagnostic test for coronary artery analysis. In present day, beta-blocker drugs are routine medications before the procedure. In our work, we aimed to study the effectiveness and reliability of use of midazolam and hydroxyzine (which have sedative and anxiolitic effects) along with esmolol (which is a short term beta blocker) in reaching targeted heart rates. The study was done with ASA I and II patients who will have multislice computerized tomography coronary angiography at the radiology department at the Kartal Kosuyolu Medical Training and Research Hospital. Method: 63 patients who are selected for multislice computed tomography coronary angiography (CTCA) and whose heart rates are over 70 pulse/minute are informed for the study and approvals are gained. Patients are randomly divided into three groups, assessed with Beck Anxiety Scale and arterial blood pressures and heart rates are noted down. An intravenous line is opened before the procedure. In group M, midazolame 0.05 mg/kg is given intravenously 10 minutes before the procedure. In group H, hydroxyzine 1 mg/kg is given perioral. In control group, no sedative anxiolytic drug is added. Every patient undergone to the multislice CTCA procedure are reevaluated. Patients who have heart rates between 70 to 80 pulse/min are given 1 mg/kg esmolol and patients with heart rates between 80 to 90 pulse/min are given 2 mg/kg esmolol intravenously. 2 minutes after the medication, patients who could not reach the target heart rates are received esmolol with an additional dose of 1 mg/kg intravenously. Patients with heart rates over 90 pulse/min are not included to the study. Intraoperative sedation is evaluated by using Ramsey Sedation Scale. In every group, arterial blood pressures, heart rates, peripheral oxygen saturations, total esmolol doses, complications (hypoxia, bradycardia, hypotension) are noted down before, at the time of and after the procedure. After the procedure, each patient is evaluated by anesthesiologist with Modified Aldrete Scale and discharged when the score becomes 10 points. Results: There is no statistically difference between three group(p>0,05).We have observed a higher number of patients with targeted heart rate in the group of patients who had hydroxyzine than the group who were given midazolam; moreover the need for esmolol was lower in the group who had hydroxyzine (p

Background/aim: The aim of this prospective study was to determine whether the preoperative oral intake of carbohydrate-rich drinks by patients undergoing a coronary artery bypass graft attenuates postoperative insulin requirements, improves postoperative patient discomfort, provides inotropic support, shortens the length of the ICU stay, and shortens the duration of postoperative mechanical ventilation. Materials and methods: This randomized prospective clinical study included 152 patients with coronary artery disease who were divided into 4 groups. Carbohydrates were administered to 3 groups at different hours and doses before operation. The fourth group had an 8-h preoperative fasting period. The inotropic and vasopressor requirements, ventilation time, and ICU stay time were recorded for all of the groups. Patient wellbeing, mouth dryness, hunger, anxiety, and nausea were assessed using VAS scores of 1-10. Results: Mouth dryness and hunger were significantly higher in the control group (P = 0.03, P = 0.02). The increase in blood glucose level was significantly higher in the control group (P = 0.04). The exogenous insulin requirement was significantly higher in the control group than in the other groups (P = 0.04). Conclusion: The administration of carbohydrates before elective cardiac surgery reduced insulin resistance. Based on the VAS scores, the intake of carbohydrates reduced mouth dryness and hunger. Overall, preoperative oral carbohydrate treatments can improve the postoperative outcomes of coronary artery bypass graft surgeries. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Valvular aortic stenosis (AS) is a major cardiac valvular disease in geriatric patients. The conventional therapy for serious AS is surgical aortic valve replacement. But most of the geriatric patients are considered to be non-operable due to anesthetical and surgical high risks. Recently, transcatheter aortic valve replacement (TAVR) is rapidly evolving new alternative therapy option for these high risk AS patients. In this study, we aimed to share our experience in patients undergoing TAVR procedure under general anesthesia (GA). Material and Method: Sixty-seven patients with serious symptomatic AS (29 male, 38 female, mean age 78.3±6.44 years) undergoing TAVR procedure under GA were evaluated retrospectively and included in this study. Results: The mean durations of the procedure and anesthesia were 159±38 min and 193±41 min, respectively. A total of 28 (41%) patients underwent blood transfusions. Vasopressor drugs were infused to 4 (0.5%) patients intraoperatively The median stay of intensive care unit and hospital stay stay were 2 (1-7), and 7 (4-60) days, respectively. Conclusion: TAVR is a challeging procedure for anesthesiologists due to the complexity of the procedure itself and also the high risk carried by the patient population who will undergo TAVR. Anesthesiologists have to ensure hemodynamic stability, and to protect the vital functions. Optimal perioperative evaluation is important for rapid and safe approach to possible complications. The growing experience in TAVR procedures will result in increased procedure success rates. [ABSTRACT FROM AUTHOR]

Objective: To investigate preoperative and postoperative blood levels of soluble intercellular and vascular cell adhesion molecules (sICAM-1, sVCAM-1) in patients with and without pulmonary hypertension (PAH) due to congenital heart disease and left to right (L-R) shunt and to determine whether these molecules can be used as reliable prognostic markers of endothelial activity to predict surgical outcomes. Methods: In this observational prospective cohort study; 42 patients, operated for L-R shunt were divided into three groups. Group 1: L-R shunt without PAH, Group 2: L-R shunt with PAH, Group 3: L-R shunt with PAH and postoperative low cardiac output syndrome (LCOS). Their sICAM-1 and sVCAM-1 levels were measured preoperatively (sICAM-0, sVCAM-0) and on the first (sICAM-1, sVCAM-1) and fifth postoperative days (sICAM-2, sVCAM-2).ROC curve for various cut-off levels of sICAM 0, sVCAM 0 in differentiating PAH patients with and without LCOS. Results: In Group 3, sICAM-0 and sVCAM-2 levels were higher than Group 1 and 2. The ROC curve demonstrated a significant association between sICAM-0 in patients with L-R shunt and PAH (Group 2 and 3) and the development of LCOS (area under the curve: 0.98, p<0.01 and 0.97, p<0.01, respectively). At a sICAM 0 concentration >359 ng/mL, there was a sensitivity of 90% and specificity of 95% for identification of LCOS in patients with L-R shunt and PAH (AUC: 0.98, 95% CI: 0.95-1.02, p<0.01). Conclusion: High preoperative sICAM-1 molecule may be used to predict postoperative dichotomous outcome in patients with PAH associated with L-R shunt. [ABSTRACT FROM AUTHOR]

Introduction: The thymus slowly involutes with age after puberty. Various stress conditions accelerate the involution of the thymus and cause changes in the histologic structure of the gland., Objective: The present study performed histomorphological and immunohistochemical (IHC) evaluations of the thymus glands removed during surgical repair in patients with cyanotic or acyanotic congenital heart disease (CHD). The thymus glands in the hypoxic group were compared to those in the non-hypoxic group. This study suggested that the activation of HIF-1 alpha promotes tumor progression and impair prognosis due to the inhibition of apoptosis, increased population of stem cells, and induction of angiogenesis also suggested that inactivation of HIF-1 alpha in tumor-infiltrated tissues could halt tumor progression and improve prognosis., Materials and Methods: The study included 76 thymus glands removed from patients who underwent an operation due to CHD. Of these cases, 38 had cyanotic CHD, and constituted the hypoxic group. The remaining 38 patients had acyanotic CHD, and constituted the non-hypoxic group. IHC procedures were performed for HIF-1 alpha, FoxP3, CD44, Bcl-2, and CD34., Results: There were statistically significant differences between the hypoxic and non-hypoxic groups only in terms of medullary enlargement toward the cortex and effacement of the corticomedullary junction. In the immunohistochemical examination for five markers, staining intensity and staining rates increased with decreasing oxygen saturation., Conclusion: It can be concluded that the activation of HIF-1 alpha promotes tumor progression and impair prognosis due to the inhibition of apoptosis, increased population of stem cells, and induction of angiogenesis.

- Abstract
Background: A retrospective evaluation was made on iatrogenic cardiac traumas requiring surgical treatment, that were induced by cardiac catheterizations and interventions performed within a 17-year period., Methods: A total of 64,911 patients underwent cardiac catheterizations and interventions from 1985 to 2002. Complications of iatrogenic cardiac traumas induced by these interventions were examined together with the surgical treatment performed within 24 hours after catheterization., Results: Iatrogenic cardiac trauma requiring prompt surgical intervention was documented in 20 patients (6 females, 14 males; mean age 51 years; range 31 to 69 years). These were due to coronary angiography/balloon angioplasty-stenting in 14 (70%), percutaneous mitral balloon valvuloplasty in four (20%), and to heart catheterization in two patients (10%). Acute cardiac tamponade was detected in 10 patients (50%) resulting from perforations to the cardiac chambers in six, coronary arteries in two, and major vessels in two patients. Surgical interventions included coronary artery by-pass in 14, mitral valve surgery in four, and repair of major vessels in two patients. Perioperative mortality occurred in two patients. Six patients developed complications contributing to morbidity, including perioperative myocardial infarction (3 patients), infection (2 patients), and prolonged intubation (1 patient)., Conclusion: In case of major cardiac complications induced during cardiac catheterizations, early diagnosis and prompt surgical intervention are of vital importance regardless of considerably high risks.

- Abstract
Background: The purpose of this study was to use serum markers for myocardial tissue damage to evaluate the effect of the severity of left anterior descending artery (LAD) lesions after 1-vessel off-pump coronary artery bypass grafting., Methods: A consecutive series of 20 patients with a totally occluded LAD and only retrograde filling (group T; n = 10) or critical stenosis (70%-99%) and only antegrade filling (group C; n = 10) were included in this study. One patient in group C who displayed no increases in the levels of markers for myocardial ischemia was excluded from the study because of the intraoperative repetition of the anastomosis. Creatine kinase activity (CK), CK-MB activity, and CK-MB mass, myoglobin, lactate, and cardiac troponin I (cTnI) concentrations were determined in venous blood samples taken immediately before and after the anastomosis and at 4, 8, 12, 24, and 48 hours postoperatively., Results: There were no perioperative myocardial infarctions. One patient in group T developed low cardiac output syndrome 48 hours after the operation and died after 1 month. His enzyme levels did not increase in the first 2 days postoperatively. Anastomosis times were similar for the T and C groups (6.85 +/- 0.9 minutes versus 8.4 +/- 2.2 minutes, respectively; P =.069). The levels of all cardiac markers except cTnI increased significantly in the first 24 postoperative hours. CK-MB activity, CK-MB mass concentration, and cTnI concentration were not different between the 2 groups. Four patients in each group were evaluated for the patency of the anastomosis, and all control angiography and myocardial scanning tests showed patent anastomoses and no ischemia., Conclusions: One-vessel off-pump coronary artery bypass grafting can be performed safely in patients with serious LAD stenosis and borderline antegrade blood flow without the need for any coronary collateral circulation support. A short anastomosis time prevents myocardial injury during off-pump coronary surgery.
