Is Veins Sticking Out Behind The Knee A Cause For Concern?
varicose veins or a clot
Detailed Answer:
HI, thanks for using healthcare magic
Distended veins in the lower limbs are most commonly related to: (a) venous disease - varicose veins
This is usually do to the fact that the valves in these veins are not working well. Varicose veins is very common as persons age.
It is usually not sudden, the veins would have been noticed before
(b)Clot-any blockage of blood flow in the veins at the pelvis or any aspect of the leg can also cause this problem.
With clots, the legs may be slightly swollen, warm, red as well
If he had no previous history of varicose veins/enlarged veins, then a clot would need to be ruled out by his doctor
This is done by examination and a special ultrasound of the blood vessels in the leg (doppler ultrasound)
I hope this helps, feel free to ask any other questions
