Hello Madam,
I understand the problem. The stagnation of
venous blood return to heart due to the defective valves in the veins (which allows the reverse flow of blood downwards) leading to
venous ulcer or
Varicose ulcer. Due to the stagnation of venous blood there will be defective arterial supply - causing the varicose ulcer not to heal.
Elevation, Compression by elasto creepe bandage may give some relief.
You must do a Vascular doppler study of both the legs to assess the involvement of veins up to what level of lower
limbs.
Without correcting the stagnation thereby increasing the arterial supply skin graft is not advised.
Previously stripping of the faulty veins were done.
Nowadays the commonly done procedure is the venous ligation
Other techniques are not of much use.
Treat the cause, then the arterial supply will be enhanced and then actively treat the ulcer even by skin graft (as the ulcer is large in size)
USG of abdomen to rule out other causes of venous obstruction is advised.
Avoid standing for a long time.
Best wishes
