Fibrin cuff theory
Did you know?
WebFibrin cuff theory - In this theory, it's speculated that venous leg ulcer arises as a result of the leakage of fibrinogen from capillaries due to chronic venous compromise. Fibrinogen hardens upon leakage, forming a fibrin cuff that surrounds the capillaries. WebFibrin is a versatile biopolymer, which shows excellent potential for tissue regeneration and wound healing [11]. Chemically it is a fibrous glycoprotein that can be found in the …
