PHLEBO-LYMPHOPATHIC ULCER Causes: • - Secondary Deep Venous Insufficiency (Post-thrombotic syndrome) or Primary Deep Venous Insufficiency • Superficial Venous Insufficiency • Functional Venous Insufficiency: Muscle-Vascular Pump dysfunction, obesity, etc. • Lymphatic Dysfunction
Serious Post-Thrombotic Syndrome with reflux in femoral, popliteal and tibial veins supra-malleolar ulcer
LITERATURE DATA • Metanalysis 1980-1998 (1249 limbs with venous ulcers) * 92% with reflux, 8% without reflux * 45% reflux only in SVS, 12% reflux only in DVS, 43% reflux in SVS and DVS (Tassiopoulos AK, Golts E, Oh DS, Labropoulos N., EJVES ) • L’incompetence of popliteal vein is a negative prognostic factor for ulcer healing (42 vs 10% ) ( Brittenden J, Bradbury AW, Allan PL, Prescott RJ, Harper DR, Ruckley CV, Br J Surg) • C) Limbs with venos ulcer, in confrontation with healthy limbs, have a decreased ejection fraction and an increased post-exercise residual (pump dysfunction..) (Araki CT, Back TL, Padberg FT, Thompson PN, Jamil Z, Lee BC, Duran WN, Hobson RW; J Vasc Surg)
CFDI AND SECONDARY DEEP VENOUS INSUFFICIENCY - POST-THROMBOTIC SYNDROME - • - possible persistent occlusions (8%) - reflux due to post-thrombotic valvular incompetence (33% isolated, 50% with thrombotic sub-occlusive changes) - morphologic and functional state of saphenous stems and of perforators - dilatation of collateral branches

ENLARGEMENT OF GIACOMINI VEIN IN POST-THROMBOTIC SYNDROME (PERSISTENT STENOSIS OF POPLITEAL VEIN AND SUPERFICIAL FEMORAL VEIN)
CFDI AND SUPERFICIAL VENOUS INSUFFICIENCY • Reflux/Retrograde flow in saphenous stems • Incompetence of saphenous junctions or extra-junction refluxes • Morphologic and haemodynamic state of perforators • Patency and competence of deep veins

PERFORATING VEINS : THEIR ROLE IN PRIMARY VARICOSE VEINS • In primary varicose veins the majority of PV in the leg has a main or single role of re-entry in the deep venous system • Bi-directional flow in PV means incompetence, but not always pathogenicity: in the “terminal” PVs of the leg the balance (the net flow) of the bi-directional flow in the systolic phase (calf contraction) and in the diastolic phase (calf relaxation) is largely in favour of the re-entry in the DVS: the PV may be incompetent, but it is not pathologic … • (Perthes, Bjordal, Bassi, Tibbs, Franceschi etc.)
BASIC KNOWLEDGE ABOUT PERFORATORS a) healthy subjects may have bi-directional flow (which were traditionally considered as pathologic in the past literature ) in 20-30% of the limbs (Coleridge- Smith et al.) b) up to 50% of the perforators in the calf have NO valves…. , thus favoring an inflow or an outflow according to the pressure gradients in the superficial and deep venous compartments (Several old and new anatomic studies)
REFLUX MOVES FROM LSV TO A TRIBUTARY AND IT FINALLY RE-ENTERS IN THE DEEP VENOUS SYSTEM THROUGH A LARGE (5 MM DIAMETER ) RE-ENTRY PERFORATOR MINIMAL OUTWARD FLOW DURING MUSCLE COMPRESSION (SYSTOLE) AND REMARKABLE INWARD FLOW DURING MUSCLE RELAXATION (DIASTOLE)
CFDI EVALUATION OVER ULCER AREA Rare incompetent perforators….
PRIMARY DEEP VENOUS INSUFFICIENCY • Reflux in deep veins • Reflux of saphenous veins • No findings compatible with previous DVT (thrombotic changes etc.) • Generalised Dilatation of deep veins • Incidence ???????

INCOMPETENCE OF SAPHENO-POPLITEAL JUNCTION AND DEEP VEIN REFLUX - Personal Experience - 162 limbs submitted to SSV surgery Pre-op: 124 limbs (76%) retrograde flow in lower tract of superficial femoral vein and in popliteal vein (mainly upper and medium tract) Post-op: 95 limbs (77%) without retrograde flow in DVS, 27 limbs (21%) with retrograde flow lasting less than 1 sec., 2 limbs with persistent retrograde flow in DVS (Cavezzi, Tarabini, Collura, Sigismondi, Barboni, Carigi; Phlébologie 2002 )
