Objective. Evaluation of the feasibility and utility of angioscopy in
the hemodynamic correction (French acronyms is CHIVA) of primary varic
ose veins disease. Experimental design. Prospective evaluation of 25 p
atients, undergoing hemodynamic correction of primary varicose disease
with intraoperative videoangioscopic guide. Patients have been select
ed according to criteria emerged from a prospective study that we had
previously conducted. Follow-up lasted 1 year (range 8-18 months). Set
ting. Department of Surgery, University of Ferrara, Italy. Institution
al practice. One-day surgery. Patients. Their selection has been carri
ed out in our Vascular Laboratory. The adopted clinical criteria of se
lection were: Primary varicose disease of the long saphenous Vein terr
itory, no previous thrombophlebitis and/or sclerotherapy. Doppler cw a
nd Duplex criteria followed were: competent deep venous system, long s
aphenous vein diameter minor than 10 mm and incompetent perforating ve
ins diameter minor than 4 mm. Interventions: 25 hemodynamic correction
s according to the CHIVA method described by Franceschi. An angioscope
, introduced through a distal collateral of the long saphenous vein, p
ermitted the precise interruption of the venous-venous shunts and of t
he superficial venous system, just below the perforators chosen as re-
entry points in the deep venous system. Measures. Clinical: varices an
d symptomatology reduction. Duplex and Doppler cw: detection of the su
perficial 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 we
re recorded (80%), in 5 patients varices reduction was observed only d
uring walking (20%). In 2 of these latter patients there was no re-ent
ry through the perforators, with a recurrent saphenofemoral reflux in
1 of them. Early complications recorded were: 2 long saphenous Vein th
rombosis (8%); 7 ecchimosis (28%) when heparine/saline solution had be
en used for angioscopic clearance. Conclusions. Intraoperative angiosc
opy is feasible and useful when the hemodynamic situation is complex a
nd the Duplex map is difficult to be interpreted by the surgeon. In th
is series the second look percentage rate has been minor compared to t
he percentage rates published so far by other authors.
