Reflux in foot veins is associated with venous toe and forefoot ulceration

The recalcitrant venous leg ulcer – a never ending story?

Introduction: In general, four particular causes of recalcitrant venous leg ulcers may be distinguished. These are foot pump insufficiency, chronic venous compartment syndrome and non-re-canalized popliteal vein thrombosis. The fourth cause of recalcitrant venous leg ulcers is lipodermatosclerosis as a symptom of severe chronic venous insufficiency.

Methods: We reviewed the literature and based on this we describe four main causes of recalcitrant venous leg ulcers and their specific treatment.

Results: Foot pump insufficiency arises when the plantar foot veins are not able to empty. Treatment should consist of physical therapy, a mechanical foot pump device and an insole. Lipodermatosclerosis may be treated by excision and split-thickness skin grafting (Vigoni procedure). Chronic venous compartment syndrome is usually caused by post-thrombotic syndrome and treatment consists of a fasciectomy, but is rarely used nowadays. Patients with non-re-canalized popliteal vein thrombosis may be supported by intermittent pneumatic compression, walking exercises, alternate standing and walking with lying down. All patients with recalcitrant venous leg ulcers must wear medical elastic compression stockings with high stiffness and high compression lifelong.

Conclusions: Patients with recalcitrant venous leg ulceration are challenging. More specific treatment will heal more of these ulcers.

Treatment of foot varicose veins: A study of 119 consecutive patients

Objective To analyze the outcomes of 119 (188 feet) patients undergoing foot varicose vein phlebectomy with and without sclerotherapy between 2013 and 2015. Methods Legs and feet were treated in one single procedure. Clinical and ultrasound assessments were carried out at 7, 30, and 90 days for visualization of the sapheno-femoral and sapheno-popliteal junctions and the deep vein system. Results Mean age was 50 ± 12 years (25-79 years); 67 patients were female (56.3%). Median venous clinical severity score was 4 (range 2-5) before and 1 (range 0-2) at 90 days ( p < 0.001). Edema and transient paresthesia were the most frequent complications (13 (10.92%) and 11 (9.24%) patients, respectively). All complications were resolved at 90 days except one case of edema (resolved after 150 days with compression stockings and lymphatic drainage manual therapy). Conclusions Symptomatic foot varicose vein intervention was safe and effective. Further studies should focus on assessment of vein-specific quality of life questionnaires.

[Foot lesions]

The foot is the target organ of a variety of internal diseases. Of upmost importance is the diabetic foot syndrome (DFS). Its complex pathophysiology is driven by the diabetic neuropathy, a vastly worsening effect is contributed by infection and ischemia. Seemingly localised lesions have the potential for phlegmone and septicaemia if not diagnosed and drained early. The acral lesions of peripheral artery occlusive disease (PAOD) have unique features as well. However, their life-threatening potential is lower than that of DFS even if the limb is critical. Notably, isolated foot lesions with a mere venous cause may arise from insufficient perforator veins; the accompanying areas of haemosiderosis will lead the diagnostic path. Cholesterol embolization (blue toe syndrome, trash foot) elicits a unique clinical picture and will become more frequent with increasing numbers of catheter-based procedures. Finally, descriptions are given of podagra and of foot mycosis as disease entities not linked to perfusion. The present review focuses on the depiction of disease and its diagnosis, leaving therapeutic considerations untouched.
