AI Summary & Key Takeaways
AI InsightMean diameter of interosseous artery was significantly higher in the study group than in control one: 2.06 ± 0.57 mm (range 1.2 t- 4.2) versus 1.46 ± 0.79 mm (range 0.8 t- 3.6); (p = 0.003).Conclusion: Although angiography was performed in a limited number of patients, interosseous artery rather than ulnar artery enlarged to compensate blood supply of forehand 25 months after harvesting the radial artery for coronary artery bypass grafting.

Abstract
Objective: The aim of this study was to evaluate angiographic changes in the ulnar and interosseous arteries, and the collateral circulation of forehand after harvesting radial artery.Methods: Forty patients were studied between June 1998 and June 2001. Study group consisted of 30 patients who received radial artery as a conduit for coronary artery bypass operation, and control group consisted of 10 patients who did not undergo any cardiac or vascular operation before. Preoperative risk factors were similar between the two groups. All patients underwent angiographic evaluation to detect coronary artery and left forehand arterial circulation.Results: Angiographic evaluation was performed 25.5 ± 2.0 months after the initial operation in the study group. Mean diameter of ulnar artery was 2.9 ± 0.59 mm (range 2.1 - 4.8) in the study group and 3.2 ± 0.8 mm (range 1.5 t- 4.7) in the control group (p > 0.05). Mean diameter of interosseous artery was significantly higher in the study group than in control one: 2.06 ± 0.57 mm (range 1.2 t- 4.2) versus 1.46 ± 0.79 mm (range 0.8 t- 3.6); (p = 0.003).Conclusion: Although angiography was performed in a limited number of patients, interosseous artery rather than ulnar artery enlarged to compensate blood supply of forehand 25 months after harvesting the radial artery for coronary artery bypass grafting.
Özet
Amaç: Bu çalışmada radiyal arter kullandığımız hastalarda ulnar arter ve interosseöz arterde anatomik veya çap değişikliği olup olmadığını araştırmayı amaçladık.Yöntem: Haziran 1998-2001 yılları arasında çalışmaya 40 hasta dahil edildi. Bu hastaların 30’unda sadece radiyal arter çıkarılan sol kol anjiyografileri yapıldı (Çalışma grubu). Kontrol grubu olarak ise, demografik bulguları aynı olan preoperatif koroner arter hastalığı araştırılmak üzere anjiyografi yapılan 10 hastanın sol kol anjiyografisi yapıldı. Hastaların hepsinin koroner arterleri ve önkolun kollateral sirkülasyonu anjiyografik olarak değerlendirildi.Bulgular: Anjiyografik değerlendirme çalışma grubunda operasyondan 25.5 ± 2.0 ay sonra yapıldı. Çalışma grubunda ulnar arter ortalama 2.9 ± 0.59 (2.1-4.8) mm iken kontrol grubunda ulnar arter ortalama çapı 3.2 ± 0.8 (1.1-5.4) mm (p > 0.05) bulundu. Ortalama interosseöz arter çapı çalışma grubunda 2.06 ± 0.57 (1.2-4.2) mm kontrol grubunda göre 1.46 ± 0.79 mm (0.8-3.6) yüksek bulundu (p = 0.003). Sonuç: Çalışmaya dahil edilen hasta sayısı az olmasına rağmen radiyal arter kullanımından 25 ay sonra interosseöz arter ön kol sirkulasyonunu kompanse etmek amacıyla ulnar artere göre daha fazla genişlediği saptandı.
