Abstract

Purpose: MDCT coronary angiography is a non-invasive procedure that we used in our study. The aim of this study is to present the technique that we used, the problems that we encountered and the data and the experience that we gain throughout our study. Materials and methods: In this study, the coronary arteries of 50 patients(28 male, 22 female) between the ages of 11 and 77(mean: 55.7) and admitted to the Cardiology and Internal medicine clinics of Haydarpafla Numune Education and Research Hospital between February 2008 and November 2008 evaluated. The brand and model of CT device we used is Somatom Sensation Siemens 40 syngo CT 2007S. 36 of 50 patients whose pulse above 70/min wereadministered oral _-blocker for 3 days before the procedure. 4 patients were omitted because their coronary arteries can not be evaluated depending on the respiration and cardiac rhythm artifacts and some of the patients have a pulse above 70/ min despite the use of _-blockers. Therefore 46 patients were included to study. Results: In 2 of 46 patients there was coronary artery origin anomaly and in 1 patient we found myocardial bridge variation. In most cases (21%), RCA and its segments could not be evaluated because of motion artifacts and other artifacts. In most of cases (14%), the cause that we could not evaluate the marginal branch of circumflex artery and distal part of circumflex artery was motion artifacts and associated venous structures. We found that; in 81 %of cases RCA was dominant artery, in 2% of cases Cx was dominant artery and in 17% of case there was co-dominance. 525 coronary artery segments were evaluated and for each coronary artery segment we calculated a stenosis percent according to the severity of stenosis. Conclusion: MDCT coronary angiography is a noninvasive technique in comparison with conventional coronary angiography. So that, the use of MDCT coronary angiography is more advantageous regarding the patient comfort, cost effectiveness and low complication rates. And because of its advantages it will be the first choice in diagnosis and investigation of coronary artery anomaly, coronary artery disease in mild and moderate risk patients and surveillance of the patients that have a history of coronary artery by-pass graft operation.

Özet

Amaç: Noninvaziv bir yöntem olması nedeniyle MDBT ile Koroner Anjiografi çekim tekniğini, teknik yönden karşılaşılan sorunları ve bu dönem içerisinde elde ettiğimiz bilgi ve birikimimizi sunmak. Gereç ve Yöntem: fiubat 2008 ile Kasım 2008 tarihleri arasında Haydarpaşa Numune Eğitim ve Araştırma Hastanesi Dahiliye ve Kardiyoloji polikliniğine başvuran, yaşları11-77 arasında (ortalama:55.7) değişen 50 hastanın (28 erkek, 22 kadın) koroner arterleri değerlendirildi. Çekim Somatom Sensation Siemens 40 syngo CT 2007S cihazı ile yapıldı. Nabzı 70atım/dk üzerinde olan 50 hastanın 36’sına çekimden 3 gün öncesinden başlayarak oral _-bloker verildi. Buna rağmen nabzı >70 atım/dk üzerinde olan, solunum ve ritm arterfaktı sebebiyle koroner arterleri değerlendirilemeyen 4 hasta çalışma dışı bırakıldı. Sonuçta 46 hasta çalışmaya dahil edildi. Bulgular: Çalışmadaki 46 hastanın 2’sinde koroner arter çıkış anomalisi ve 1’inde de myokardial bridge varyasyonu saptandı. Çalışmamızda hareket artefaktları ve diğer artefaktlar nedeniyle en fazla değerlendirilemeyen koroner arter RCA ve segmentleriydi (%21). Sol sirkumşeks arter marjinal dalının ve distalinin yeterli değerlendirilememe nedeni genelde hareket artefaktları ve eşlik eden venöz yapılardı (%14). RCA dominansı % 81, Cx dominansı %2 oranında ve kodominant dolaşım %17 oranında bulunmuştur. 525 koroner arter segmenti de- ğerlendirilmeye alınmış olup her bir koroner arter segmenti için stenoz şiddetine göre oranlar belirtilmiştir. Sonuç: Noninvaziv bir yöntem olan MDBT’nin, invazif bir metod olan KKA ile karşılaştırıldığında hasta rahatı, maliyeti ve potansiyel komplikasyonlar açısından avantajları nedeniyle KAH tanısı için düşük ve orta riskli hastalarda tarama ve tanı amaçlı, koroner arter anomalisi tespitinde, koroner by-pass, hastalarda ise takip amacı yla noninvazif etkin bir görüntüleme yöntemi olarak yerini alacağı aşikardır.
