- Deep Blood Vessel Apoplexy (DVT): DVT is a blood clot that creates in a deep blood vessel, usually in the leg. It can be life-threatening if the clot takes a trip to the lungs.
- Vascular Conditions: Particular vascular problems, such as spider veins or venous lack, can trigger noticeable changes in the look of blood vessels.
