The needles point to valvular dilatations in a segment of excised vein. These dilatations are actually the visible varicosities. The tissue just distal to the valve is very attenuated. This is the reason that in many instances, multiple phlebectomies are needed because the vein can tear at these locations.

In this image, the needles are pointing to the valves after opening the vein. You can see that the vein tissue is very thickened in this patient. This is secondary to long standing venous hypertension. Notice how thin the vein wall is just distal to the valve. In larger veins, this is the mechanism of venous aneurysm formation---turbulent flow distal to a malfunctioning valve. This valve is considerably thicker than you would normally see due to the duration of high pressure.
