How does factor v leiden deficiency and thrombosis link together?

Let's start by defining thrombosis- it refers to a lump or plug of a blood clot, usually occurring in a vein.* It also, refers to the clotting process and forming of the clot.

Clotting is a complex step-by-step process that involves many different stages and ingredients. If something goes wrong with one or more of these steps, the clotting process can be overactive or under active; making the blood too thick (with clotting and plugging tendencies) or too thin (bleeding time is increased and it is difficult to stop the loss of blood.)

Factor V Leiden refers to a disorder where one of those ingredients causes the blood to clot abnormally, making the blood 'thick' and too likely to clot too quickly, with resulting thrombosis. This disorder runs in families and is suspected when the family has a history of blood clots in the veins.

My dear niece has this disorder and her life was saved by a board-certified hematologist, when other physicians could not figure out what was wrong with her and her life was in jeopardy. She is thriving today and has learned to manage this disorder in her daily life.
