Abstract

Objectives: The left internal mammarian artery (LIMA) is the most commonly used arterial graft for coronary artery bypass grafting (CABG) and occlusion of LIMA side branches during surgery is important for avoiding myocardial ischemia. In this study, we investigated the incidence of patent LIMA side branches in patients undergoing CABG and evaluated changes in LIMA flow with the use of TIMI frame count in patients with and without LIMA side branches. Study design: The study included 38 patients (27 males, 11 females) who underwent coronary angiography due to symptoms and complaints that appeared after CABG. In all the patients, a LIMA graft was used for revascularization of the left anterior descending artery. Coronary angiographies were performed after a mean of four years following CABG. Angiograms were examined with respect to the presence of LIMA side branches and LIMI flow was assessed by the TIMI frame count method. Results: Patent LIMA side branches were detected in seven patients (18.4%). The mean TIMI frame counts were 27.3±3.4 and 15.7±2.3 in patients with and without a LIMA side branch, respectively (p

Özet

Amaç: Koroner arter baypas cerrahisinde greft amacıyla sık kullanılan sol internal mamaryan arterde (LIMA) yan dalların anastomoz öncesi kapatılması, cerrahi sonrası çalmaya bağlı miyokard iskemisini engellemek için son derece önemlidir. Bu çalışmada, koroner baypas cerrahisi geçirmiş hastalarda LIMA’da yan dal varlığının ne kadar sıklıkta görüldüğü, yan dalı olan ve olmayan LİMA’lar arasında TIMI kare sayısı açısından fark olup olmadığı araştırıldı.Çalışma planı: Çalışmaya koroner baypas cerrahisi geçirdikten sonra yakınmaları nedeniyle koroner anjiyografi ile incelenen 38 hasta (27 erkek, 11 kadın) alındı. Tüm hastalarda sol ön inen arter revaskülarizasyonu için LIMA grefti kullanılmıştı. Koroner anjiyografi cerrahiden sonra ortalama dördüncü yılda yapıldı. Bütün hastaların koroner anjiyografi görüntüleri incelenerek LIMA yan dal sıklığı saptandı ve LIMA akımları için TIMI kare sayıları hesaplandı.Bulgular: Yedi hastada (%18.4) LIMA’da yan dal saptandı. LIMA’da yan dalı olan ve olmayan hastalarda TIMI kare sayısı ortalaması sırasıyla 27.3±3.4 ve 15.7±2.3 bulundu (p
