7 Why does Vein Surgery Have Such a Bad Reputation? Historically the procedures were morbidHistorically the procedures were morbid High incidence of recurrence perceived as bad resultsHigh incidence of recurrence perceived as bad results Severe forms of venous insufficiency including refluxing perforators resulted in recurring stasis ulcers Severe forms of venous insufficiency including refluxing perforators resulted in recurring stasis ulcers

8 Perforators Give Veins A Bad Name Linton procedure had a reported 19% wound complication rateLinton procedure had a reported 19% wound complication rate

9 Perforators Give Veins A Bad Name Perforators are a more likely source for recurrent varicose veins than neo-vascularsationPerforators are a more likely source for recurrent varicose veins than neo-vascularsation Recurrence is perceived as bad resultsRecurrence is perceived as bad results

10 Perforators Give Veins A Bad Name Severe forms of venous insufficiency including refluxing perforator veins resulted in recurring stasis ulcersSevere forms of venous insufficiency including refluxing perforator veins resulted in recurring stasis ulcers

11 Significance of Perforator Veins Source for reflux in the superficial venous systemSource for reflux in the superficial venous system Reflux from perforator veins has been associated with venous stasis ulcersReflux from perforator veins has been associated with venous stasis ulcers Communication between deep and superficial venous SystemsCommunication between deep and superficial venous Systems Reflux from perforator veins can result in varicose veinsReflux from perforator veins can result in varicose veins

12 Communication Between Venous Systems Not all badNot all bad Allows patients to recover from vein insults such as injuries and DVTAllows patients to recover from vein insults such as injuries and DVT Allows us to perform vein ablative procedures on the saphenous and other superficial veinsAllows us to perform vein ablative procedures on the saphenous and other superficial veins

13 Communication Between Venous Systems Not all goodNot all good Source for reflux in the saphenous veinSource for reflux in the saphenous vein Associated with venous stasis ulcersAssociated with venous stasis ulcers Reflux from perforators can cause non saphenous varicose veinsReflux from perforators can cause non saphenous varicose veins Source for new and recurrent varicose veinsSource for new and recurrent varicose veins

38 Endoluminal Ablation Perforators

39 Endoluminal Ablation of Perforators Minimally invasive proceduresMinimally invasive procedures Office basedOffice based Local anesthesiaLocal anesthesia VNUS ClosureVNUS Closure Laser ablationLaser ablation My experienceMy experience

40 VNUS Closure Device FDA approvedDevice FDA approved Billing Code recommendationBilling Code recommendation Recommended protocol using ultrasound guidance and impedance to verify positionRecommended protocol using ultrasound guidance and impedance to verify position

41 Disadvantage VNUS Closure Device awkward and expensive, especially for add on perforator veinsDevice awkward and expensive, especially for add on perforator veins Protocol less effective than thoughtProtocol less effective than thought Impedance less useful than flashImpedance less useful than flash In general other closure procedures have inferior results to laserIn general other closure procedures have inferior results to laser

42 Laser Perforator Technically simplerTechnically simpler Less expensive to perform; can treat perforator at time of other veins and not incur increase procedural costsLess expensive to perform; can treat perforator at time of other veins and not incur increase procedural costs Results should be superior to closureResults should be superior to closure
