Management of Incompetence in the Axial Veins
Vascular Health Clinics
Introduction
½ adult men, 2/3 adult women have varicose veins.
Severe chronic insufficiency seen in 20% of working men and women.
Varicosities can range in severity from venectasias to protuberant tortuous varicosities, with associated dermatitis, ulcers, severe pigmentation.
Introduction
• Venous disorders are divided into acute thromboembolic events or chronic stasis issues.
• Chronic issues includes varicose veins, venous incompetence (superficial and deep).
• Primary varicose veins can be treated for cure.• Deep venous reflux is treatable but not curable• Varicosities are a symptom of venous disease, not
just a cosmetic problem.• Regardless of treatment modality, recurrence rates
are high.
Varicose VeinsEpidemiology
• 50% of the population has some venous symptoms• 20-25% of women and 10-15% of men will have
visible varicose veins• 10% of venous ulcerations are secondary to purely
superficial disease• 3% of the population with some skin change• Superficial reflux contributes to ulceration in 70%
of cases
Venous Anatomy of the Leg
Anatomy of the Saphenofemoral Junction
• Five Named Branches– Long (greater) Saphenous– Anterior-lateral branch– Anteriormedial branch– Superficial Epigastric– External Pudendal
Varicose VeinsPathophysiology
• Valvular incompetence with axial reflux
• Venous pressure increases leading to dilation, lengthening and further valve damage
• Fluid and protein extravasation in soft tissue
Varicose VeinsMechanism of Development
• Perforator Incompetence– Ropey– Reticular– Spider
Anatomy of Telangiectasia
Function of The Skeletal Muscle Pump
• Superficial veins have mainly reservoir function
• Skeletal muscle pump responsible for majority of blood return in upright position (90%)
Risk Factors
• Female sex• Increased age• Obesity• Pregnancy• Geography• Race
Symptoms
• Achiness, heaviness• Stinging, burning• Edema• Warmth• Muscle spasms• Phlebitis• Bleeding• Skin changes
CEAP Classification
• Clinical
• Etiologic
• Anatomic
• Pathophysiologic
CEAP Classification
• Clinical Classes– 0 asymptomatic– 1 telangectasia– 2 varicose veins– 3 limb edema– 4 skin changes– 5 healed venous ulceration– 6 open venous ulceration

Varicose Veins• Spider Veins• Reticular Veins• Ropey Varicosities
Phlebectatic Corona
Hemosiderin Deposition
Lipodermatosclerosis
Atrophie Blanche
Bleeding Intradermal Varices
Venous Ulceration
Cosmetic Benefit• Most common reason to
seek treatment• Baby Boomers reaching
retirement age• Cosmetic benefit will
occur in 2-3 weeks but not maximal until 6-12 months
Compression
Stockings Solaris Wrap
Pump Lymphatic Decongestive Therapy
Graded Compression Stockings• PROS
– Good effectiveness for relief of symptoms
– Effective at reducing risk of ulceration
– Effective at reducing risk of phlebitis
– Effective at slowing development or recurrence
• CONS– Difficult to don– Cosmetically unappealing– May create tourniquet effect
if not worn properly– Can be poorly tolerated in
neuropathy– Contraindicated with
arterial insufficiency
Algorithm for the TreatmentSymptomatic Venous Insufficiency
Principles
• Eliminate all sources of reflux
• Treat proximal to distal
• Largest to smallest• Important to create a
pre-op map of reflux
Surgical Therapy for Varicose Veins
• Flush Ligation of the Saphenofemoral Junction
• Stripping of the GSV• Individual
Ligation/Avulsion/ Interruption Secondary Branches
Complications of Surgical Therapy
• Hematomas• Paresthesias
– Up to 40%• Wound complications• Neovascularization of the SFJ
– 60% at 39 yrs– 30% requiring reintervention (Fischer,J Vasc
Surgery 2001;34:326-40.)
Trivex Powered Phlebectomy
• Minimally invasive• General or spinal
anesthetic• Learning curve• Good results
Subfascial Endoscopic Perforator Surgery (SEPS)
Subfascial Endoscopic Perforator Surgery
Microphlebectomy
Complications of Microphlebectomy
• Bruising• Phlebitis• Scarring• Retained Varicosities
Superficial Thrombophlebitis
Valve Replacement• Damaged valve • Surgical repair- poor long
term results• Percutanous techniques
being developed but so far outcomes poor
• Possible stem cell therapies on the horizon
Thermal Ablation of the Greater Saphenous Vein
• Done in the office• Mild sedation (oral benzodiazepine)• Local anesthetic• Tumescent anesthesia• 45-60 minute procedure• Minimal post-op pain• Return to work in 24 hours• More likely to be reimbursed by insurance
Before and After Closure• Secondary branches
will require secondary procedure
• Phlebectomy or sclerotherapy
• May be done concomitantly or staged (debated)
• Regression of perforator incompetence 60%
Tumescent Anesthesia
• High Volume of dilute lidocaine with epinephrine
• Provides anesthesia• Acts as a heat sink to
protect surrounding structures
• Relatively exsanguinates the vessel to improve heating (contact) and reduce bleeding
Pre-op Assessment
• Power-wave doppler of reflux
SFJ Ultrasound
Thermal Ablation
• Radiofrequency- heat delivered through direct contact with vessel wall
• Laser-980-1320nm heat delivered to the water component of blood and steam damage to the wall

VNUS (radiofrequency ablation)
Radiofrequency Ablation with ClosureFast Device
Post-closure Instructions
• Compressive wrap x 24 hours with leg elevation
• Class II graded compression stocking around the clock for 1 week
• Class II compression stocking x 3-4 weeks• Non-steroidal anti-inflammatory tx
Laser Ablation
Outcomes of Thermal Ablation
• Radiofrequency Ablation– 91.4% closure at 1 yr– 90.1% closure at 2 yr– 86.3% closure at 3 yr– 86.1% closure at 4 yr– (VNUS Clinical
Registry)
• Laser Ablation– 98.5 technical success– 1.5 couldn’t complete– 1 week 100% closure– 97.7 closure at 3
months– 96.2 at six months– 93.2 at 2 yrs– (Min et al
Endovascular today suppl. Nov/Dec 2004.)
Complications of Endoluminal Therapy
• Endoluminal Heat Induced Thrombus (EHIT)
• Grade 1-4
Comparison of Thermal Ablation and Surgical Removal
• EVOLVeS trial– Multicenter,
prospective, randomized control study
• Thermal ablation superior to stripping in all outcome variables– Faster recovery– Less pain– Fewer adverse events– Superior quality of life
score (p<.05)– Fewer recurrences at 2
yrs 91.2% vs 91.7%
Sclerotherapy• Hypertonic saline
– Painful, risk of ulceration• Polidocanol
– Least painful, less staining, most expensive
• Sotradecol– Less painful, FDA approved,
moderate staining• Glycerine
– Difficult to use, no staining, minimally painful
• Sodium Morrhuate– Rarely used
Sclerotherapy Results
Foam Sclerotherapy
• Works only with detergent sclerosants– Polidocanol– Sotradecol
• Sclerosant aerated 4:1 with air or CO2 to create “microbubbles”
• Pre-foamed options- Varithena
Foam Sclerotherapy• Can be deployed with only
a few injections• Painless
Foam Sclerotherapy• Potency and contact time increased• Foam can be directed with ultrasound
Complications of Foam Sclerotherapy
• Transient neurological symptoms (1:100 sessions)– Visual aura– Amaurosis fugax– Hemiballismus– Seizure– Stroke (1 case)
• Increased risk with history of migraine
• ? Patent foramen ovale
Liquid SclerotherapyBefore After
Complications of Sclerotherapy• Itching, Stinging, Burning• Muscle Cramps and Bruising• Extravasation• Hyperpigmentation• Talangectatic Matting• Phlebitis• Ulceration• Allergic Reaction; local or systemic• Neurologic• DVT (rare)
Trapped Hematoma
• Expected; if left undrained increased hyperpigmentation
• Drainage can be more painful than sclero
• Patients are warned ahead of time
Telangectatic Matting
• Usually represents deeper level of insufficiency
• May resolve over time• May respond to repeat
injection of cutaneous laser
Urticaria
• Usually transient• May ulcerate• Usually stings and
then may become pruritic
Ulceration
• Inadvertent extravasation
• Hemangioma vs spider vein
• Forceful injection
What’s New
• FDA News Release:• FDA approves closure system
to permanently treat varicose veins
Venaseal Sapheon SystemOnly one access site. One injection.No heat or pain.No phlebitis.Currently more expensive than EVLT or RFA.Unknown long term success rate.
