title: Angiovideo-assisted hemodynamic correction of varicose veins.
abstract: OBJECTIVE
  Evaluation of the feasibility and utility of angioscopy in the hemodynamic correction (French acronyms is CHIVA) of primary varicose veins disease.
  
  
  METHODS
  Prospective evaluation of 25 patients, undergoing hemodynamic correction of primary varicose disease with intraoperative videoangioscopic guide. Patients have been selected according to criteria emerged from a prospective study that we had previously conducted. Follow-up lasted 1 year (range 8-18 months).
  
  
  METHODS
  Department of Surgery, University of Ferrara, Italy. Institutional practice. One-day surgery.
  
  
  METHODS
  Their selection has been carried out in our Vascular Laboratory. The adopted clinical criteria of selection were: Primary varicose disease of the long saphenous vein territory, no previous thrombophlebitis and/or sclerotherapy. Doppler cw and Duplex criteria followed were: competent deep venous system, long saphenous vein diameter minor than 10 mm and incompetent perforating veins diameter minor than 4 mm.
  
  
  METHODS
  25 hemodynamic corrections according to the CHIVA method described by Franceschi. An angioscope, introduced through a distal collateral of the long saphenous vein, permitted the precise interruption of the venous-venous shunts and of the superficial venous system, just below the perforators chosen as re-entry points in the deep venous system.
  
  
  METHODS
  Clinical: varices and symptomatology reduction. Duplex and Doppler cw: detection of the superficial blood flow re-entry, in the deep venous system, through the perforators and identification of recurrences or new refluxes. Pre and postoperative Ambulatory Venous Pressure and Refilling Time have also been measured.
  
  
  RESULTS
  In 20 patients symptoms and varices relief were recorded (80%), in 5 patients varices reduction was observed only during walking (20%). In 2 of these latter patients there was no re-entry through the perforators, with a recurrent sapheno-femoral reflux in 1 of them. Early complications recorded were: 2 long saphenous vein thrombosis (8%); 7 ecchimosis (28%) when heparine/saline solution had been used for angioscopic clearance.
  
  
  CONCLUSIONS
  Intraoperative angioscopy is feasible and useful when the hemodynamic situation is complex and the Duplex map is difficult to be interpreted by the surgeon. In this series the second look percentage rate has been minor compared to the percentage rates published so far by other authors.
