Conservative hemodynamic surgery for varicose veins is a minimally invasive
nonablative technique that preserves the saphenous vein and helps avoid excision
of varicosities.
It represents a physiologic approach to the surgical treatment of varicose veins
based on knowledge of the underlying venous pathophysiology gained through detailed
duplex scanning. A change in venous hemodynamics is attained through fragmentation
of the blood column by interruption of the refluxing saphenous trunk.
closure of the origin of the refluxing varicose branches, and preservation
of the communicating veins that drain the incompetent varicose veins into
the deep venous system.
After surgery, varicose veins regress through a reduction in hydrostatic
pressure and efficient emptying of the superficial system by the musculo-venous pump.
Obvious advantages of this technique are that it is done in an ambulatory
setting, minimizes the risk of surgical complications, and permits a rapid
return to full activity.
The long-term hemodynamic improvement and recurrence rate of this technique
remains to be established.
