dc.description.abstractKRON K OBSTRÜT F AKC ĞER HASTALIĞININ ZOLE KORONER ARTERCERRAH S ERKEN DÖNEM SONUÇLARINA ETK SVII. ÖZET:Amaç:Koroner arter hastalığı ve kronik obstrüktif akciğer hastalığı ( KOAH ) sıkkarşılaşılan bir birlikteliktir. KOAH, koroner arter cerrahisinde mortalite ve morbiditeaçısından tespit edilen en önemli preoperatif risk faktörlerinden biridir. Bu yazıda, izolekoroner arter cerrahisi uyguladığımız hastalarda KOAH' nın erken dönem cerrahisonuçlar üzerine etkilerini araştırdık.Materyal ve Metod:Eylül 2001-Şubat 2006 tarihleri arasında kliniğimizde izole koroner bypasscerrahisi uygulanan 1032 hasta çalışmaya dahil edildi. Sol ventrikül anevrizma onarımı,karotis endarterektomi yapılanlar ve re-operasyonlar da çalışmaya alınmadı. KOAHnedeniyle yatarak tedavi öyküsü olan veya solunum fonksiyon testlerinde beklenenFEV1 değeri <%75 olan toplam 153 hasta (%15) KOAH grubu olarak kabul edildi. Gerikalan 879 hasta ise kontrol grubunu oluşturdu. KOAH grubundaki hastaların yaşortalamaları (p=0.001), hipertansiyon (p=0.016) ve obezite (p=0.01) oranları kontrolgrubuna göre istatistiksel olarak anlamlı bir şekilde fazla bulundu.40Bunun dışında, cinsiyet dağılımı, anjina tipi, fonksiyonel kapasite, sigara içiciliği,diyabet, sol ana koroner hastalığı, sol ventrikül ejeksiyon fraksiyonu, renaldisfonksiyon, karotis arter hastalığı ve geçirilmiş serebrovasküler olay oranlarıbakımından iki grup da benzerdi.Bulgular:Kardiyopulmoner bypass ve kros-klemp zamanları, sol internal mammariyanarter kullanma oranları, postoperatif farmakolojik veya mekanik destek ihtiyaç oranları,perioperatif MI ve postoperatif atrial fibrilasyon gelişme sıklığı her iki grupta benzerdi.Mekanik ventilasyon süresi KOAH grubunda anlamlı derecede uzamış idi ( KOAH 8.9± 4.5 saat vs. Kontrol 7.9 ± 3.1 saat; p=0.001 ). KOAH grubunda gastrointestinalkomplikasyon ( kanama / perforasyon ) oranı %2.6 iken kontrol grubunda %0.5 idi (p=0.01 ). Sternal ayrışma oranı da KOAH grubunda daha yüksekti ( KOAH %1.96 vs.Kontrol %0.34; p=0.049 ). Postoperatif diğer komplikasyon oranları iki grupta dabenzerdi. Yoğun bakımda ortalama kalış süreleri iki grupta yakın olmakla beraber,ortalama hastanede kalış süresi KOAH grubunda daha uzamış idi ( KOAH 6.8 ± 1.8gün vs. Kontrol 7.3 ± 3.9; p = 0.009 ). Hastane mortalitesi açısından iki grup arasındafark yoktu.Sonuçlar:Koroner arter cerrahisi uygulanacak hastalarda KOAH mevcudiyeti mortaliteyietkilememektedir. Bununla beraber, morbidite oranı ciddi şekilde artmaktadır. Yakıntakip, iyi bir preoperatif değerlendirmeyle ve mümkün olduğunca KPB'tan kaçınmaylamorbidite oranları daha aşağıya çekilebilir.41
dc.description.abstractVIII. SUMMARY:Background: Coronary artery disease and chronic obstructive pulmonarydisease (COPD) have been a common association. COPD has been identified as animportant preoperative risk factor for mortality and morbidity in patients undergoingcoronary artery bypass grafting (CABG). The aim of the study was to assess the impactof COPD on the early postoperative outcome of patients undergoing CABG.Methods: Between September 2001 to February 2006, 1032 patientsunderwent CABG at our clinic. Patients underwent carotid endarterectomy, leftventricle aneurysm repair during the CABG session and reoperations were excluded.One hundred fifty-three (15%) of these individuals had required therapy for thetreatment of chronic pulmonary compromise or had an FEV1, 75% of predicted value.These subjects were defined as COPD group, and the remaining 879 were defined ascontrol group.Results: The patients who had COPD were significantly older than those whodid not have this disease (p = 0.001). Compared to the control group, COPD patientshad a significantly higher prevalence rates of hypertension (p = 0.016) and obesity(p = 0.01). The 2 groups were statistically similar with respect to sex distribution,proportion of cases with unstable angina and left main coronary artery disease. Therewere also no significant differences between the groups with respect to prevalence ratesof hyperlipidemia, smoking, diabetes; proportions of patients with previous MI orcerebrovascular accident; or proportions of patients with carotid artery disease or renaldysfunction. There was no significant difference between the mean cross-clamp andmean cardiopulmonary bypass times, mean numbers of grafts per operation, use of leftinternal mammary artery grafts, proportions of patients who required inotropic support,intraaortic balloon pump support, and incidences of perioperative MI and postoperative42atrial fibrillation for the 2 groups. The proportion of patients who received arterialgrafts only, and who had off-pump surgery were significantly higher in control group(p = 0.001, p = 0.012, respectively). The incidence of proximal anastomosis performedduring the cross-clamp period was also significantly higher in control group(p = 0.026). The COPD group had a significantly longer mean mechanical ventilationtime (8.9±4.5 vs. 7.9±3.1 hours for COPD vs. control, respectively; p = 0.0001). TheCOPD group had statistically higher incidences of gastrointestinal complications(bleeding/perforation), and sternal dehiscence (p = 0.01, p = 0.049, respectively). Therewere also no significant differences between with respect to mean intensive care stay,but overall hospital stay was significantly longer in COPD group (6.8±1.8 vs. 7.3±3.9days for COPD vs. control, respectively; p = 0.009). The rates of hospital mortalitywere 2.6 % in the COPD group and 1.9% in the control group (p = 0.589).Conclusion: Our findings indicate that COPD is not associated with increasedmortality in patients undergoing CABG. However, morbidity of patients with COPDafter CABG was significantly high. Morbidity ratios might be lowered by close care,improving preoperative evaluation and by avoiding CPB as possible as.Key words: COPD; coronary artery bypass grafting; surgical outcomes43en_US
