What is the medical term meaning Abnormal condition of blood clots?

Thrombosis is the medical term meaning abnormal condition of blood clots.
Thrombosis is the medical term meaning condition of blood clots. A generic condition resulting in increased likelihood of producing blood clots is called a hypercoagulable disorder.

Most people will develop blood clots under certain conditions, such as after surgery, sometimes after long trips, or with certain conditions which cause you to be more likely to have blood clots - pregnancy, taking Birth Control pills, etc.

Clotting is predisposed when any of three conditions are present: endothelial injury, stasis, or hypercoagulability. These three conditions together are called Virchow's triad.

There are certain hypercoagulable disorders that are heritable. These include antithrombin III deficiency, thrombin gene mutation, anticardiolipin antibody, lupus anticoagulant, Factor V Leiden deficiency, Protein C or S deficiency, and methyltetrahydrofolate reductase (MTHFR) deficiency.

All these conditions predispose a person to develop venous thrombosis, and if several DVTs develop, the person may need to be on lifelong anticoagulation with warfarin to prevent pulmonary emboli and pulmonary hypertension.
