Chronic Venous Insufficiency/Varicose Veins: Prevalence • The prevalence of varicose veins in Western countries Epidemiology classically ranges between 25 to 30% in females and 10 to 20% in males 1 Duesseldorf/Essen civil servant study of 9261 employees, • 27% of subjects were identified with small cutaneous and/or reticular veins whereas only 9% had typical varicose veins 2 • Edinburgh Vein Study- over 80% of the studied population manifested telangiectatic and reticular veins. 3 1.

Chronic Venous Established and potential risk factors for varicose veins (VV) and Insufficiency/Varicose Veins: chronic venous insufficiency (CVI). Prevalence • Clinical manifestations of CVI such as dermal hyperpigmentation, eczema, and edema vary from <1% to 17% in males and <1% to 20% in females • The prevalence of active or healed venous stasis ulcerations is lower, occurring in ~1% of the population � Collectively, CVI and varicose veins comprise the most common vascular condition Adapted from Beebe-Dimmer et al. Ann Epidemiol 2005;15:175-184 . 2
3 Types of Lower Socioeconomic Impact Extremity Veins • Stasis ulcerations are responsible for the loss of ~ 2 million working days and $ 3 billion/year in the US 1 • Chronic venous insufficiency responsible for 1 to 3% of the total health care budget in developed countries 2,3 • CVI is associated with a reduced QOL which is proportional to the severity of venous HTN 4 Perforating Vein 1.

CVI does not cause Venous Disease: marked pitting edema! Treatment Guidelines • Make the correct diagnosis � History and Physical � Appropriate testing • Document any arterial disease • Document level and degree of reflux Venous Disease: Treatment Guidelines Varicose Veins: Treatment • Try conservative methods first • Educate the Patient regarding Blair Vermilion, M.D. realistic outcomes and potential Associate Professor of Clinical Surgery complications Ohio State University • Compliance, Compliance, Compliance 9

Smaller � Can be worn at night diameter areas have increased pressure with equal tension � Use for Dermatitis, Ulcers � Increase pressure by applying multiple � Can be changed once/week layers Venous Disease: Venous Disease: Compression Therapy Compression Therapy • Gradient support stockings • Bandaging Principles � Low working pressure—minimal effect � Start at the base of the toes on deep venous return � Apply no more than 50% stretch � High resting pressure—excellent reflux prevention � Overlap ~50% to avoid skin pinching � Uniform application with right size � Oblique turns (not circular) to minimize constriction � Can be hard to get on 11

Venous Disease: Sclerotherapy Sclerotherapy � Maintain post injection compression � Venous thrombosis � Ambulate patient � Arterial Injection/injury � Re-evaluate @ 7 to 10 days � Select solution and concentration based � Nerve Injection/injury on vein size � Skin Discoloration � Telangiectatic matting Venous Disease: Venous Disease: Sclerotherapy Sclerotherapy • Contraindications to Sclerotherapy Of Varicose Veins • Complications of Sclerotherpy � Bedridden Patient � Vasovagal Attack � Severe Arterial Disease � Allergic reaction � Hypercoagulable state � Pregnancy � Skin necrosis � Morbid Obesity � Poor tolerance of compression hose � Allergies to the agents used 13
EndoVenous Laser EndoVenous Laser Treatment Treatment • Ambulatory procedure • Results in ablation of treated vein • Can be done in most cases under local, tumescent anesthesia with • The laser introduces thermal energy sedation to the venous tissues, causing irreversible localized venous tissue • Patients typically resume activity damage immediately and see results quickly, with minimal chance of scarring, sutures, long hospital stay, lengthy recovery, or surgical complications EndoVenous Laser EndoVenous Laser Treatment Treatment • Laser energy (most commonly from • Disadvantages: an 810-nm diode laser) is delivered inside the vein through a bare laser � 3% failure rate fiber that has been passed through a � Ecchymosis sheath to the desired location � Paresthesias • The laser is continuously fired (or in pulses) as the laser fiber is gradually � DVT (1%) withdrawn along the course of the � Not as effective on larger (>1.5cm.) veins vein until the entire vessel is treated 14
