The Effects Of Internal Mammary Artery Harvesting Techniques OnPulmonary Functions

Öz

Background: Although it impairs the pulmonary functions, internal mammary artery harvesting with pedunculated or skeletonized technique has been proved to have better long-term outcomes. Even if there is no full consent, some reports insisting on the advantages of skeletonized LIMA harvesting to decrease pulmonary side effect. Our aim is to compare the postoperative respiratory functional status in patients using these two techniques. Method: Totally 80 patients were included in the study and were divided into two groups; in group P (n=40) LIMA was dissected as a pedunculated graft and in group S (n=40) LIMA was prepared as a skeletonized graft. Pulmonary functions were evaluated on the 6th and 7th postoperative days and were compared between the two groups. Results: Forced expiratory volume in the 1st second (FEV1) and forced vital capacity (FVC) were the measured data. The decrease in FVC was more prominent in group P (p

İnternal Mammaryan Arter Hazırlama Tekniklerinin Akciğer Fonksiyon Testlerine Etkileri

Öz

Giriş: Sol internal mammaryan arter (LİMA), kullanılması akciğer fonksiyonlarında bozulmalara yol açmakla birlikte, ister pediküllü ister skeletonize hazırlansın koroner bypass ameliyatlarında geç dönem açıklık oranları en iyi olan grefttir. Henüz kesin görüş oluşmamakla birlikte skeletonizasyon tekniğinin akciğerler üzerine olan yan etkileri azalttığını iddia eden yayınlar vardır. Amacımız akciğer fonksiyon testlerinde bu tekniklere bağlı olarak bir fark oluşup oluşmadığını ortaya koymaktır. Yöntem: Çalışmaya LİMA'sı skeletonize olarak çıkarılan ardışık 40 hasta (grup S) ve pediküllü olarak çıkarılan yine ardışık 40 hasta (grup P) olmak üzere toplam 80 hasta dahil edildi. Preoperatif ve postoperatif (6. veya 7. gün) solunum fonksiyon testleri karşılaştırıldı. Bulgular: Solunum fonksiyon testlerinde 1. saniyedeki zorlu expiratuvar volüm (FEV1) ve zorlu vital kapasite (FVC) değerleri ölçüldü. FVC'nin Grup P'de grup S'ye göre daha fazla azaldığı tespit edildi (p
