Abstract

Objective: Atheromatous plaques in the ascending aorta are major risk factors for strokes caused by macroembolization after coronary artery surgery. Detection of plaque formations and changes in the surgical strategy are very important. This study was planned to compare value direct palpation and multislice computerized tomography to establish aortic plaques and to establish clinical predictors of aortic calcification. Methods: Fifty-four patients who underwent coronary bypass surgery were included in this prospective and diagnostic study. Proximal portion of each patient’s aorta was evaluated with multislice computerized tomography and was compared with direct palpation. The efficacy ofintraoperative palpation to predict calcifications was studied with ROC analysis and the predictors of aortic plaque formation were analyzed using logistic regression analysis. Results: Atheromatous plaques were detected with palpation in four patients (7.4%), and with multislice tomography in six patients (11.1%). The aortic instrumentation was changed in two patients (3.7%) and strategy was changed in one patient (1.8%).According to the ROC analysis, when multislice computerized tomography was taken as the reference, intraoperative direct palpation was 67% sensitive and 100% specific to predict aortic plaques. Logistic regression analysis of the risk factors showed that the older age was the only significant risk factor (OR – 1.3, 95%CI -1.114-1.568, p=0.001) for plaque formation in the aorta. Neither stroke nor other neurological disorders have been observed during the study.Conclusions: It can be stated that multislice computerized tomography is more effective to show aortic plaques, but it is not sufficient. Multislice tomography may give additional information about the ascending aorta and the opportunity to visualize the aortic arch. It can bepreferred in patients with aortic aneurysm or dissection.

Özet

Amaç: Assandan aorttaki ateromatöz lezyonlar, makroembolizasyonun en sık kaynağı olarak koroner baypas operasyonları sonrası görülen inmeler içinde oldukça önemlidir. İnmenin engellenmesinde plakların tespiti ve cerrahi strateji değişiklikleri hayati öneme sahiptir. Bu çalışmada aterom plaklarının saptanmasında direkt palpasyonla çok kesitli bilgisayarlı tomografi (ÇKT) karşılaştırılmış, postoperatif inmeyle ilişkilerinin araştırılması ve assandan aort kalsifikasyonunun klinik prediktörlerinin belirlenmesi amaçlanmıştır.Yöntemler: Çalışmaya kardiyopulmoner baypas kullanılarak aortokoroner baypas operasyonu uygulanacak 54 hasta alındı, çalışma prospektif ve diyagnostik bir çalışma olarak planlandı. Her hastanın proksimal aortası preoperatif çok kesitli tomografi ile değerlendirildi. İntraoperatif dijital muayene bulgularının assandan aorttaki kalsifikasyonu öngörme kuvveti, ROC analiz yöntemi kullanılarak araştırıldı, plak oluşumunun prediktörleri lojistik regresyon analiz ile belirlendi. Bulgular: Dijital muayene ile 4 hastada (%7.4), ÇKT ile 6 hastada (%11.1) assandan aortta kalsifik plak görüldü. Palpasyonla tespit edilen lezyonlar sebebi ile iki hastada (%3.7) enstrümantasyon, bir hastada ise (%1.85) operasyon stratejisi değiştirildi. Yapılan ROC analizinde, çok kesitli tomografi referans alınarak, peroperatif dijital muayenenin plak varlığını öngörmede sensitivitesi %67, spesifisitesi %100 olarak bulundu. Regresyon analizine dahil edilen risk faktörlerinden, ileri yaş (OR – 1.3, 95% CI -1.114-1.568, p=0.001) hariç hiçbirinin plak gelişimine olan katkısı istatistiksel olarak anlamlı bulunmadı. Çalışma süresince hiçbir hastada inme veya nörolojik defisit görülmedi. Her iki yöntemle de plak saptanmayan bir olguda proksimal anastomoz için aort açıldığında plak tespit edildi, anastomoz başka bir bölgeye yapıldı.Sonuç: Çok kesitli tomografinin assandan aorttaki aterom plaklarının saptanmasında direkt palpasyona üstün olduğu, ancak yeterli olmadığı söylenebilir. Kalsifiye plakları saptayabilmekle beraber iki hastada nonkalsifiye ve ülsere plağı saptayamamıştır. Ancak anevrizma, disseksiyon gibi ek patolojiler hakkında preoperatif bilgi verebilmesi ve arkus aorta incelemesinin de yapılabilmesi nedeniyle seçilmiş hastalarda yararlı olabileceğini düşünüyoruz.
