Definition

1. Noun:
   • The formation or presence of a blood clot (thrombus) inside a blood vessel: "Thrombosis" refers to the pathological process where a clot forms and remains attached within the circulatory system, potentially obstructing blood flow.

Usage

• Thrombosis is a medical term used to describe a specific condition involving clot formation within the vascular system. It is often modified by the type of vessel (e.g., venous, arterial) or its location (e.g., deep vein, cerebral sinus).

Examples

• Noun:
  • Deep vein thrombosis (DVT) is a serious condition where a clot forms in a deep vein, usually in the leg.
  • The patient was hospitalized due to a cerebral venous sinus thrombosis.
  • Arterial thrombosis can lead to a heart attack or stroke.

Advanced Usage

• "to develop thrombosis": to begin to have or form a thrombus.
  • Patients who are immobile for long periods are at risk of developing thrombosis.
• "risk of thrombosis": the likelihood of a clot forming.
  • Certain genetic factors increase a person's risk of thrombosis.

Synonyms
