Venous Ulcer //
There are three kinds of vascular leg ulcers: arterial, venous, mixed.
Cause: tissue ischemia due to arterial stenosis or occlusion. Most of the situations are associated with atherosclerosis.
They are most commonly seen on toes (Figure 1) or ankles (Figure 2).

Superficial venous hypertension due to reflux or obstruction of the leg veins is attributed to the major cause of the venous ulcer. Most of the venous ulcers occur on the medial or lateral aspects of the ankle area, followed by anterior or medial aspects of middle calf. The common findings are thickening and hyperpigmentation over the affected area (Figure 3) that progress to a unhealed ulcer (Figure 4).

TREATMENT OF VENOUS ULCER
The first step is to find out the source of venous hypertension. Common causes are reflux of great or small saphenous veins, incompetent perforating vein or venous insufficiency post deep vein thrombosis.
Endovenous laser ablation (EVLA) (Figure 5) or Radiofrequency ablation (RFA) are the most useful method to abolish reflux of great or small saphenous veins.

Use injection microsclerotherapy or ultrasound-guided sclerotherapy to close the branch varicosities.
Use specialized dressings, such as Aquacel foam or Aquacel Ag Surgical, to absorb exudate, prevent secondary bacterial infection, moisturize the wound, and hence speed up wound healing (Figure 6).

Use class II and above compression stockings to abolish reflux from incompetent perforating vein and improve venous return and reduce edema (Figure 7).

Wound infection or necrosis need surgical debridement and antibiotic treatment. A large and deep wound may need skin graft.
