Alright. I also studied later after posting it here, in a few papers that the presence of valves in the veins is another reason of the increased susceptibility of veins to have more thrombosis . However, thank you very much for your insights.
Agreed with the above. 0ral factor X inhibitors like apixaban may be used in venous thromboembolic disorders. In case of arterial thrombotic complications aspirin is preferable because platelet thrombi are the principle pathogenic step in the thrombus-formation process.
Of course, I agree with the answers above. Additionally, venous endothelial cells produce less NO, which reduces their anti-thrombotic capacity and contributes further to their susceptibility to thrombogenesis.
likely a combination of slow flow, potential for stasis with mild compression like bed ridden status , long flights , the valves in veins and definitely the thinner and weaker layer of smooth muscles in veins as compared with arteries.
