Psoriasis and subdermal venous dilatations

Psoriasis in association with dilated veins (sub dermal) the legs. It is some times difficult to differentiate which clinical condition is the cause for the symptoms of the person. This is possible when psoriasis is seen along with the varicose veins. These patients complain of symptoms such as pain, discomfort, heaviness and difficulty in walking with skin lesions (dry, scaly) and few dilated veins in the legs. We have noted in our clinic especially in women who were treated for the skin disease (assumed as skin allergy), significant importance was given to the dilated veins by their family physicians and dermatologists. They were referred to the vascular surgical clinic with view to consider varicose veins surgery. In such patients a detailed examination for arthritis is necessary as this may be part of psoriasis (10-20% of patients). Counseling of the patients and their families about the psoriasis (skin disease) is important before any surgical therapies can be considered. A Dermatologist who can consider “ Foam- Sclerotherapy” along with skin therapies may be ideally suited for treating for such vein disorders in association with the skin diseases. But in India, very dermatologists in our city are considering foam Sclerotherapy for varicose veins in their clinics. Probably in future more number of dermatologists may consider foam Sclerotherapy in their practices.

Psoriasis (pronounced /səˈraɪəsɪs/) is a non-contagious disorder which affects the skin and joints. It commonly causes red scaly patches to appear on the skin. The scaly patches caused by psoriasis, called psoriatic plaques, are areas of inflammation and excessive skin production. Skin rapidly accumulates at these sites and takes on a silvery-white appearance. Plaques frequently occur on the skin of the elbows and knees, but can affect any area including the scalp and genitals. In contrast to eczema, psoriasis is more likely to be found on the extensor aspect of the joint

Venous Ulcer in Chronic Venous insufficiency

Chronic venous disease is noted as large venous ulcers around the ankle. In India, it is not uncommon to see this type of advanced forms of chronic venous disease (see Fig.)
There are many reasons which make this type presentation a common feature in the govt general hospital out patient clinics. Some times the plastic surgeons attempt skin grafting for these ulcers after control of infection with regular dressing. But these ulcer recur due to the underlying venous insufficiency. Venous reflux in the superficial veins is addressed by Flush ligation of the SFJ, SPJ and perforators. But the deep venous insufficiency is left to subside or regress with the external compression therapies in the post operative period for few years. Very few hospitals are able to consider some form of therapy for the deep vein reflux across the globe and in India.

Catheter directed foam Sclerotherapy

ABSTRACT
The authors present results on chemical ablation of 50 great saphenous veins (GSVs) using 3% polidocanol foam delivered via a standard coaxial endovenous sheath. The sheath was steadily withdrawn with one hand, while injecting between 5 and 8cc of sclerosing foam out the endhole. The amount of sclerosant was a function of the length of the treated vein.

All 50 veins were occluded at the 1-week follow-up visit which included examination by color flow duplex imaging. One vein had a 10 cm long open segment in the middle of the thigh. One patient suffered a pulmonary embolus post-procedure. Most patients had advanced disease, 43 veins were in limbs with CEAP class 4-6. There was no mention of vein diameter in the study. The authors correctly point out that vasospasm in the GSV caused by catheterization may alter the flow of the foam and result in its unintended distribution. The authors also mention a newly launched catheter-assisted vein sclerotherapy device (KAVS, F care Systems NV, Aartselaar, Belgium) which comprises a balloon catheter capable of occluding the GSV without occluding the common femoral vein. They had no results or experience with the device.
