Fibrin cuff theory

WebThe fibrin cuff theory involves the accumulation of fluid containing fibrin into the pericapillary space. This cuff with impaired fibrinolysis increase the diffusion barrier inhibits the repair process and maintains the inflammatory process. Another theory is the trapping of growth factor by fibrin and other macromolecules preventing the healing. WebAccording to the fibrin cuff theory, increased venous pressure causes leakage of macromolecules from plasma into perivascular space. This initiates the conversion of fibrinogen to fibrin and acts ...

WebThe fibrin cuff theory, which suggests that fibrinogen leaks from dilated capillaries to form a fibrin cuff, leading to reduced diffusion of oxygenated blood and ulceration6,16 The leukocyte entrapment theory, which states that venous hypertension reduces the pressure gradient between the arteriolar and venular end of capillaries, WebThe fibrin cuff theory holds that elevated venous pressures in the lower limb lead to an increase in the size of the capillary bed and widening of the interstitial pores. This allows leakage through the capillary pores of fi-brinogen, which polymerizes to fibrin. Fibrin then forms a cuff around the capillaries. The deposition of pericapillary ... 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.
