In order to facilitate the healing of venous stasis ulcerations, podiatric physicians must ensure appropriate referrals to vascular specialists in order to address the underlying cause of venous insufficiency. Accordingly, here are a couple of minimally invasive options that have emerged for the treatment of patients with venous ulcers.
Sclerotherapy. Sclerotherapy is a microinjection procedure that requires no pain medication or surgery. It is a procedure used to treat blood vessels or blood vessel malformations. Some DPMs perform sclerotherapy themselves while others refer patients to a vascular surgeon for the procedure. Physicians have used sclerotherapy in the treatment of varicose veins for over 150 years.
Like varicose vein surgery, the technique of sclerotherapy has evolved over time in the treatment of venous ulcers. Modern techniques including ultrasound guidance and foam sclerotherapy are the latest developments in this evolution.
One would treat the abnormal veins by injecting a solution called a sclerosant. This will seal the vein off from the rest of the vein network in the leg, allowing the body to naturally redirect blood flow to healthy veins.
Endovenous laser treatment (ELT). Endovenous laser treatment is a quick, minimally invasive laser treatment for varicose veins that requires no hospitalization. With ELT, one would insert a small optic fiber through a needle into the varicose vein under ultrasound guidance. Once the laser is activated, as the fiber optic fiber is removed from the vein, it heats and closes the vein.
Once the vein is closed, the blood that was circulating through the vein naturally re-routes to other healthy veins. Overall, the laser energy minimizes the vein walls, shrinking them and closing the faulty vein so that blood cannot flow through it.
