Abstract

The viability of an island or a free flap is primarily depen¬dent on arterial blood flow. Intensely decreased or totally ceased flow has a deleterious effect on flaps but the effects of moderately diminished flow is not clearly documented. We proposed a hypothesis that moderate constriction of an arterial pedicle of an island flap may decrease total blood flow and cause ischemia. We elevated bilaterally hind limb composite flaps with only femoral artery and femoral vein remaining intact in male rats. On one side (experimental side) femoral artery (arterial pedicle) was externally constricted with a rigid metal ring, 50 % narrowing the lumen. Blood flow rates were measured by means of an electromagnetic flowmeter at immediate and 72 nd hours. On the other side (control side ) blood flow rates were recorded without narrowing the artery. Histological changes were examined at 72nd hour by means of light and electron microscopy. Arterial blood flow was lower in experimental side at immediate and 72nd hours (p

Özet

Bir ada flebinin veya serbest flebin yaşayabilirliği öncelikle arteriyel kan akımına bağlıdır. Büyük oranda azalmış veya tamamen durmuş bir akım, flep üzerinde hayati bir etkiye sahiptir, fakat kısmen azalmış bir akımın etkileri açıkça ortaya konulmamıştır. Bir ada flebinin arteriyel pedikülündeki kısmi daralmanın, toplam kan akım miktarını azaltarak iskemiye neden olabileceği hipotezinden yola çıktığımız çalışmamızda; erkek sıçanlarda, iki taraflı arka bacak kompozit flepleri, sadece femoral arter ve femoral ven intakt kalacak şekilde kaldırıldı. Bir tarafta (deney taraf) femoral arter (arteriyel pedikül), rijid bir metal halka ile lümeni %50 daraltacak şekilde eksternal olarak daraltıldı. Kan akım miktarları, elektromanyetik akım ölçer aracılığı ile akut dönemde ve 72. saatte ölçüldü. Diğer tarafta ( kontrol tarafı), kan akım miktarları arteriyel daraltma yapılmaksızın kaydedildi.. Histolojik değişiklikler; 72. saatte ışık mikroskopisi ve elektron mikroskopisi aracılığı ile incelendi. Deney tarafında, arteriyel kan akımı akut dönemde ve 72. saatte daha düşük bulundu (p
