CLASSIFICATION
Many classi cations other than REVAS have been devel-
115,116
oped concerning recurrences,
but they have not been
widely used. At the consensus meeting held in 1998 we
decided to use both the previously reported CEAP clas-
1
si cation and a speci c REVAS classi cation.
is new
classi cation was intended to serve everyday clinical practice as well as research studies into epidemiology, clinical
status, and treatment of recurrent varicose veins. Asurvey was undertaken in order to test its intraobserver and
84
interobserver reproducibility.
e conclusion of this
study was that intraobserver reproducibility is quite satisfactory, and making slight changes in the answers to one
question, might increase interobserver reproducibility.
However, the fact that interobserver reproducibility was
less than intraobserver reproducibility re ects conditions
of real life, and especially interobserver di erences. Such
interobserver di erences may arise from interobserver
technical di erences, but this nding emphasizes the need
for validating a duplex scanning protocol and a standardizing duplex scan reports (see below, “Investigations”)
e REVAS classi cation (Table 30.1) includes six
items: T is for topographic sites of REVAS; S for sources of
re ux; R for degree of re ux ; N for nature of sources ( Nss
for same site of previous surgery, and Nds for di erent sites);
P for contribution from a persistent incompetent saphenous
trunk; and F for possible contributory factors ( Fg for general
and Fs for speci c factors).
This classification has been used only for REVAS,
but it might be used for any kind of recurrence after
operative treatment in combination with the CEAP
classification. Nevertheless it looks that a new classification—PREVAIT classification—not yet drawn up
might be a bettertool.
DIAGNOSIS
MODES OF PRESENTATION
Patients who have previous nonconservative treatment
may consult their physicians for various reasons: unsightly
recurrent varicose veins or related emotional problems that
are especially common in female patients, discomfort (in
other words venous-related symptoms), appearance of cuta-
neous or subcutaneous changes, concerns about the health
risk related to their veins, or limitation of activity. Also
PREVAIT may be found at routine follow-up.
MEDICAL HISTORY
Family and Personal History
Family history of varicose veins and personal history including pregnancies, hormone therapy, super cial thrombophlebitis, deep vein thrombosis, and so forth, should be recorded.
Previous Treatment
e date of previous treatment(s) for varicose veins must be
reported, as well as the age of the patient at the time of operative treatment, occurrence of new pregnancies a er initial

PHYSICAL EXAMINATION
Presence and intensity of the various vein-related symptoms
have to be noted:pain, throbbing, heaviness, itching, feeling of swelling, night cramps, heat or burning sensations or
restlesslegs.
Some data are available on patients presenting
PREVAIT, including severity of leg symptoms and clinical

and particularly numbness must be documented. E ciency
of the calf pump has to be assessed and particularly degree of
ankle motion. Arterial pulses should be checked and ankle
brachial index calculated. A general examination including
abdominal palpation should be performed, and possible obesity can be identi ed by body mass index calculation.
I N V E S T I G A T I O N
Many investigations have been used in the past to assess
REVAS. At the moment there is a large consensus for recommending DS in all cases of PREVAIT. is investigation
provides anatomical and hemodynamic data including
•
e topographical sites of recurrence that can be mapped,
•
e possible sources of re ux from the deep venous
system to the super cial (Figures30.2 and30.3),
•
e intensity or degree of re ux,and
•
e nature of sources keeping in mind that causes have
to be classi ed di erently if recurrence occurs in a site
previously treated ornot.

In few select cases ascending venography in threedimensional imaging may give complementary valuable
information. PREVAIT related to re uxive pelvic varices
is better investigated by selective descending phlebography
( Figure30.4 ). Other investigations such as air plethysmography and ambulatory pressure measurement may be useful
for research studies but not for daily practice.

Compression
Compression in varicose veins is frequently recommended
and improves both symptoms and signs, but it does not cure
the disease.
D r u g s
In varicose veins phleboactive drugs are prescribed mainly
to improve edema and symptoms. e most commonly
used are avonoids, but othersexist.
Operative Procedures
Operative procedures share the same goals:(1)to supress
re ux from deep to super cial systems when present, (2)to
supress varices, and (3)in some speci c cases to suppress
deep vein abnormality to prevent new recurrences.
e nal goals are multiple: decrease the ambulatory
venous pressure, prevent worsening of chronic venous
disorders, avoid further recurrences and of course improve
patients’ in terms of cosmetic appearance, symptoms andsigns.
Ultrasound-Guided Sclerotherapy
Sclerotherapy has been used for a very long time for
treating REVAS, but ultrasound-guided sclerotherapy
(USGS) has improved the e cacy. Di erent protocols
have been used, but no comparative study with other operative treatment is available. Recently polidocanol foam has
entered the ring, but currently no consensus exists on the
techniques, doses, concentrations, or sclerosing agents for
PREVAIT.
Nevertheless one of the main advantages of sclerotherapy with or without foam is that the process is cheap,
simple, less invasive, and repeatable. USGFS can both obliterate the re uxive varices and suppress most of the leak
points between deep and super cial venous system including pelvic, SFJ or SPJ, and perforator re ux as well as varices
not connected to the deep venoussystem
Open Surgery
Procedures can be classi ed into three groups according
to their objective, and should be used in combination.
1:
the SFJ or SPJ, if the site has previously been operated and
depending on the extent of postoperative brosis, redo
surgery may be di cult. It is recommended that the deep
vein be approached rst in order to avoid dissection of scar
tissues, lymphatic nodes, and cavernoma. e last does not
need to be ablated. Flush ligation of the stump is then performed and can be completed by patch interposition at
the SFJ for avoiding new recurrence.

using this procedure without resection of the
groin cavernoma but with combined resection of varices
(saphenous trunks and/or tributaries) had only 4.2% recurrences at the SFJ at 4.9years mean follow-up (range 3 to
7years) in 119 extremities. Nevertheless, 22.6% of patients
had di use varices, with a new site of incompetence between
the deep and super cial systems.

De Maeseneer
has compared the results at 5years of two
nonrandomized groups with and without patch, respectively
group 1 and 2 in a prospective study. All patients had recurrent
SFJ incompetence. At 5-year follow-up, recurrent thigh varicosities were observed in 58% of group 2 versus 26% of group1.
ermal Ablation
Only one series reported a randomized control trial in patients
with recurrent varices initially treated by isolated SFJ ligation
and presenting a persistent re ux at the SFJ and in the patent
56
GSV trunk.
Radiofrequency caused less pain and bruising
and was performed more quickly than traditional open surgery.
Pelvic and Gonadal Vein Embolization
At 6-month follow-up, 90% of 215 patients treated by
embolization of gonadal and pelvic veins were signi cantly
improved in both signs and symptoms, but relief of pelvic
pain or lower limb symptoms or signs were not evaluated
separately ( Figure30.5 ).

Chemical Ablation

in several studies. e Birmingham study has the longest
follow-up and is fully documented in terms of ultrasound

investigation.

PREVAIT a er thermal or chemical ablation, but it seems reasonable to state that results should be as good as a er surgery.

withDS.

INDICATIONS
Indications for treating patients with recurrent varices.
Patients can be roughly divided into two groups:
1. Patients complaining of symptoms or aesthetic
concerns, or presenting with signs of chronic venous
disease (C
–C 6 ). In all cases these patients need to be
2
investigatedbyDS.
2. Subjects attending a routine follow-up. e decision
whether to undertake DS or not depends on the
presenting complaint and physical ndings. In practice,
DS is almost alwaysdone.
A S Y M P T O M A T I C
When hemodynamic or anatomic abnormalities are found
in asymptomatic patients without severe signs who are not
concerned by their minor varices as cosmetic problems the
decision to treat depends of the severity of the noninvasive
ndings. In all cases follow-up is required, because abnormal DS ndings precede symptoms andsigns.

S Y M P T O M A T I C
In symptomatic patients presenting with recurrent varices
and hemodynamic anomalies, operative treatment must be
considered.
Although there is no randomized controlled trial comparing redo surgery to chemical ablation, there is a consensus for treating recurrences with USGFS as rst-line

treatment
for reasons discussed above. In very few cases
when duplex scanning reveals an intact and large incompetent saphenous stump at the SFJ or SPJ with a massive re ux
lling the varicose network, redo surgery at the junction
should be considered in combination withUSGFS.
In patients with severe disease (C
–C 6 ) with

PREVAIT and primary deep vein axial re ux, USGFS and
valvuloplasty in association must be considered in active
patients reluctant to wear lifelong compression or with

Of proven validity, with a high level of convergence
within patient groups, when applied across geographic,
linguistic, and cultural boundaries.
Currently there is no quality-of-life tool that is su ciently sensitive to detect clinically signi cant changes and
ful ll all of the above criteria; and a number of di erent
generic health care questionnaires have been developed. In
recent years the most popular tools for the measurement
of venous disease have included the Nottingham Health
Pro le (NHP), the EuroQol (EQ-5D), and the short form
36 (SF36). e EQ-5D and SF36 are also validated in other
major languages and are widely accepted internationally.
Although applicable across a spectrum of disorders to allow
a comparison of health-related quality of life across populations of patients with di erent diseases, these generic tools
are frequently insu ciently sensitive to detect clinically signi cant changes in speci c disease processes over time. For
this reason, disease-speci c quality-of-life tools have been
designed, in order to be sensitive to these key dimensions
in quality of life that are a ected by the disease. In 2007
the American Venous Forum (AVF) published a consensus
of recommended reporting standards speci c to endovenous ablation of varicose veins, which supported the use of
a combination of disease-speci c and generic quality-of-life
questionnaires.

Q U A L I T Y O F L I F E
Health is de ned by the World Health Organization as
“a state of complete physical, mental and social well being
and not merely the absence of disease”; and measuring
health and improving quality of life is of major importance
throughout all branches of medicine. In 1997 Beattie etal.
suggested that the ideal quality-of-life measure shouldbe:
•
Equally applicable to any disease process or outcome,
•
Equally applicable across all levels of illness and degrees
of invalidity,and
MEASUREMENT OF OUTCOMES
In developing an outcome measure, the concepts of validity,
reliability, and responsiveness arevital.
12
Validity is the extent to which a questionnaire measures
what is intended. is is frequently evaluated by comparing a new measure with an established one (criterion validity). In the absence of a gold standard, a construct’s validity
can be measured; this allows comparison of a new tool with
objective or clinical ndings.
