İki taraflı internal torasik arter çıkarılmasının sternum kanlanmasına etkisi: Tek foton emisyonlu bilgisayarlı tomografi çalışması

Amaç: İnternal torasik arterin (ITA) iki taraflı çıkarılmasının sternum kanlanmasına etkisi tek foton emisyonlu bilgisayarlı tomografi (SPECT) ile incelendi. Çalışma planı: Çalışmada kardiyopulmoner bypass ameliyatı uygulanan 40 hasta iki gruba randomize edildi. Yirmi hastada (grup 1; 16 erkek, 4 kadın; ort. yaş 62±8; dağılım 44-68) iki taraflı ITA kullanılırken, 20 hastada (grup 2; 14 erkek, 6 kadın; ort. yaş 65±6; dağılım 46-72) sol ITA kullanıldı. Ameliyat öncesi, ameliyat sonrası erken (ort. 6.4±1.1 gün) ve geç (ort. 135.9±14.1 gün) dönemdeki sternum kanlanması SPECT ile değerlendirildi ve karşılaştırıldı.Bulgular: Ameliyat öncesi ve ameliyat sırasındaki veriler iki grupta, ameliyat süresinin grup 2’de daha kısa olması dışında benzerdi. Ameliyat öncesi sternum SPECT incelemeleri de iki grupta farklılık göstermedi. Erken ameliyat sonrası SPECT incelemelerinde iki grupta da sternumun her iki yarısında kanlanmada anlamlı azalma gözlendi (p

The effect of bilateral internal thoracic artery harvesting on sternal vascularity: a single-photon emission computed tomography study

Background: We evaluated sternal vascularity after bilateral internal thoracic artery (ITA) harvesting with singlephoton emission computed tomography (SPECT). Methods: Forty patients undergoing coronary artery bypass surgery were randomized into two groups. Bilateral ITA was used in group 1 (n=20; 16 men, 4 women; mean age 62±8 years; range 44 to 68 years), while the left ITA was used in group 2 (n=20; 14 men, 6 women; mean age 65±6 years; range 46 to 72 years). Sternum SPECT was performed before surgery and in early (mean 6.4±1.1 days) and late (mean 135.9±14.1 days) postoperative periods for comparison of sternal vascularity.Results: Preoperative and intraoperative findings were similar in two groups except for the operation time, which was significantly shorter in group 2. Preoperative SPECT findings were similar, as well. Early postoperative scans showed dramatic decreases in blood flow into both sides of the sternum in both groups (p
