Harry Ma MD, PhD Assistant Professor of Surgery University of Oklahoma Tulsa, Oklahoma Department of Surgery Slide 2 Disclosures None Slide 3 Outline and Objectives Defining chronic venous disease Clinical manifestations Diagnostic evaluation Treatment Non-operative Operative Slide 4 Spectrum of Disease Spider veins (telangiectases) Reticular veins Varicose veins Edema Chronic skin changes Ulcers Slide 5 Impact of CVD Most common form of vascular disorder Chronic Venous Disease: 25 million people in US Health care cost: $1 to 3 Billion dollars annually Indirect cost: ~2 million work days lost annually Slide 6 Definitions Telangiectasias - are a confluence of dilated intradermal venules less than one millimeter in diameter. Reticular veins - are dilated bluish subdermal veins, one to three millimeters in diameter. Usually tortuous. Varicose veins - are subcutaneous dilated veins three millimeters or greater in size. They may involve the saphenous veins, saphenous tributaries, or nonsaphenous superficial leg veins. Slide 7 Definitions of Skin Changes Lipodermatosclerosis: localized chronic inflammation and fibrosis of the skin and subcutaneous tissue Atrophie blanche: localized, often circular whitis and atrophic skin areas surrounded by dilated capillary spots and hyperpigmentation Venous Ulcer: full thickness skin defect Slide 8 CEAP classification Clinical Etiology Anatomy Pathophysiology Slide 9 Clinical Classification C0: no visible or palpable signs of venous disease. C1: telangiectasies or reticular veins. C2: varicose veins. C3: edema. C4a: pigmentation and eczema. C4b: lipodermatosclerosis and atrophie blanche. C5: healed venous ulcer. C6: active venous ulcer.

Therapy based on photothermolysis (light induced thermal damage). Laser light heats the target tissue inducing thermal injury Wavelength of light is chosen based on the target structure's chromophore Radiofrequency A high frequency alternating current resulting in energy that heats the adjacent vein walls to the probe which alters the protein structure of the vein effecting its closure Slide 28 Complications of ablation Nerve injury Which is Better? Equivalent therapy Similar outcomes Success rates >95% for both (N=159) Improvement in QoL surveys and VVQ surveys Cochrane review in 2014 13 randomized trials included 3081 patients total Complication rates equivalent Efficacy: equivalent for laser, RFA, foam sclerotherapy and ligation and stripping Slide 30 Sclerosing Agents Hypertonic Saline Chromated glycerin Nonchromated glycerin Monoethanolamine oleate Sotradecol (STS) Polidocanol Foam Slide 31 Mechanism of action and use Endothelial damage Thrombosis Resultant sclerosis and closure of the vein For telangiectasias Reticular veins Perforator veins More recently incompetent GSV Slide 32 Ultrasound Guided Foam Sclerotherapy First reported in 1995 Mixed with air or CO2 Bubble size of 100 m or less Ration of sclerosant to air or CO2 is usually 1:4 Slide 33 Limitations and complications Large veins Phlebitis 3-8% Embolus (CVA) Visual disturbance DVT Failure or recurrence Anaphylaxis Slide 34 Short term outcomes 1 year follow-up equivalent QoL improvement 72% success rate (vs 89% for EVLA) Two year follow-up in patients with ulcers 85% healing rate Slide 35 Long term outcomes 5-8 year follow-up of 285 patients 89% had improvement in QoL survey and AVSS 15% required repeat treatment Slide 36 References Andr P, Hartwell D, Hrachovinov I, Saffaripour S, Wagner DD.
