TL;DR: The CEAP Task Force has adopted the revised Delphi process and made several changes, including adding Corona phlebectatica as the C4c clinical subclass, introducing the modifier "r" for recurrent varicose veins and recurrent venous ulcers, and replacing numeric descriptions of the venous segments by their common abbreviations.
Journal ArticleDOI
Duplex assessment of venous reflux and chronic venous insufficiency: The significance of deep venous reflux
Harold J. Welch,Carolyn M. Young,Adam B. Semegran,Mark D. Iafrati,William C. Mackey,Thomas F. O'Donnell +5 more
TL;DR: Reflux in the deep venous system plays a significant role in the progression of chronic venous insufficiency, with significant axial reflux contributing to ulcer formation.
Journal ArticleDOI
Endovenous ablation of the great saphenous vein may avert phlebectomy for branch varicose veins.
TL;DR: Endovenous ablation of the GSV can be performed safely and effectively as the initial treatment for lower extremity varicose veins and because most patients show clinical improvement after RFA, an algorithm of reassessment of the limb and branch varicOSE veins several months post-RFA allows most patients to defer stab phlebectomy.
Journal ArticleDOI
Comparison of descending phlebography with quantitative photoplethysmography, air plethysmography, and duplex quantitative valve closure time in assessing deep venous reflux
Harold J. Welch,Eleni C. Faliakou,Robert L. McLaughlin,Susan E. Umphrey,Michael Belkin,Thomas F. O'Donnell +5 more
TL;DR: In the evaluation of patients with severe chronic venous insufficiency who are candidates for phlebography and surgery, quantitative duplex measurement of TVCT gives the best noninvasive assessment of the severity of deep venous reflux.
Journal ArticleDOI
Failure of Carotid Stump Pressures: Its Incidence as a Predictor for a Temporary Shunt During Carotid Endarterectomy
Kelly Jj,Allan D. Callow,Thomas F. O'Donnell,Kevin McBride,Bruce Ehrenberg,Korwin S,Harold J. Welch,Ronald M. Gembarowicz +7 more
TL;DR: A review of the complication rate in the various study groups indicates that the use of intraoperative EEG is a safe indicator of cerebral ischemia during carotid endarterectomy regardless of stump pressure.
