Management of Chronic Venous Insufficiency
Superficial and deep venous insufficiency start with leaking valves, leading to venous
reflux from deep vessels towards the superficial network and venous dilatation, finally
resulting in decompensation. Heaviness, cramps, pains and swellings are some of the
common symptoms. Varicose veins of the lower limbs are associated with a hereditary
predisposition but develop in response to various triggering factors such as pregnancy,
aging, trauma or following deep venous thrombosis.
Management involves use of phlebotonic agents, bandages, gradient stockings,
injection sclerotherapy, and surgery.
Management of Leg Swellings
These are due to venous or lymphatic diseases.
Deep venous thrombosis (DVT)s are common in patients confined to bed and is
potentially serious. Economy Class Syndrome, in air travel, refers to the same
condition.
Pulmonary embolism is a major complication resulting from thrombus formation, often
within the deep venous system of the leg & occasionally, from pelvic and subclavian vein
thrombosis; it is associated with a high mortality. Deep venous thrombosis not only
presents an immediate risk of life but is also associated with late sequelae such as
post-thrombotic syndrome (venous ulcer) and varicose veins.
Early management involves anticoagulation (heparin and warfarin), thrombolytic therapy &
surgery. In chronic DVT states, filter insertion into the inferior vena vaca prevent
pulmonary embolism.
Management of Leg Ulcers
Most of the leg ulcers are of arterial, venous or diabetic in nature. Arterial ulcers are
due to insufficiency due to blockage or narrowing of blood vessels. Venous ulcers are due to
reflux due to build up of back pressure in blood vessels & valve incompetency. Diabetic
ulcers are due to mixture of both arterial and nerve problems.
Management of Acute or Chronic Ischaemic Limbs
Management of arterial ischemia ulcers or gangrene involves medical therapy with angioplasty,
arterial bypass or sometimes amputations. Venous ulcers can be managed in the same way
as chronic venous insufficiency while diabetic ulcer is managed non-surgically
(conservatively) except when there is occlusion, then, angioplasty or bypass may be
needed.
Thrombolytic Therapy
In situ arterial thrombosis is the most common indication for local thrombolytic
therapy. In the developed world it causes 40-58% of cases of acute limb ischaemia.
Stenosis is the most common cause of in situ arterial thrombosis in the iliac &
femoral-popliteal segments. Thrombolysis offers the opportunity of dissolving the
thrombus & unmasking the stenosis, which can then be treated with percutaneous
transluminal angioplasty or surgery.
Aneurysm in the popliteal artery, ectasia, bypass graft thrombosis and hyperthrombotic
states are other conditions where thrombolytic therapy can be useful.
Management of Abdominal Aortic Aneurysms (AAA) Open Surgical Repair or Endovascular
Stenting
AAAs represent a degenerative process that has often been attributed to
atherosclerosis because of the elderly age of the patients affected & the universal
atherosclerotic changes in their arteries.
If the physician feels there is a risk the abdominal aortic aneurysm may bust, he or
she may choose one of these two types of treatment:
- Open surgical repairs
- Endovascular repair
Management of Carotid Artery Disease
Stroke or cerebrovascular disease constitutes an important cause of disability among
the elderly. Thromboembolic disease accounts for about 75 % of new strokes each year.
Of these, carotid artery occlusive disease is probably the single most important causal
factor in the development of cerebrovascular ischemia. Transient monocular blindness or
amaurosis fugar and transient ischemic attack (TIA) constitute important warning signs
of impending stroke. Duplex scanning is an important non-invasive form of investigation
to confirm diagnosis. In severe cases of symptomatic disease, apart from medical therapy,
carotid endarterectomy is an established modality of treatment where carotid artery
stenosis exceeds greater than 70%.
Venous Access Procedures
- Reconstruction of arteriovenous fistula for dialysis in chronic renal failure
- Insertion of Hickman line, tunnelled central line, etc.
- Insertion of portacath / vasoport unit
- Angioplasties / stenting of stenotic fistulas or subclavian veins.
Repair of Arterial Trauma
Vascular trauma is often part of major motor-vehicle accidents. Common vessels involved
are the popliteal, superficial femoral, femoral and brachial arteries and their
associated veins. Early referral by 6-12 hours ensures success.
ELVeS : New Treatment For Varicose Veins
Varicose veins are a frequently occuring condition with up to 40% of women & 20% of men likely
to suffer from symptoms such as fatigue, pain and swelling of the lower limbs. Soft tissue
breakdown (dermatitis), bleeding, ulceration can result if left untreated.
The Endo Laser Vein System(ELVeS) is a versatile system that treats venous incompetence.
Treatment can be performed on a Day-Case basis under local anaesthetic with many benefits for
the patient including minimal discomfort, short treatment time, excellent aesthetic results
and a rapid return to normal activities.
The laser optical fibre is inserted into the vein and closed from the inside by the thermal
laser energy. Procedure is approximately one hour. The potential side effects are minor and
include thermal injury (burn) to the overlying skin or intervening tissue, perforation of the vein,
superficial phlebitis (inflammation of the vein), hyperpigmentation (darkening of the overlying skin)
or revascularisation (growth of new veins).
ELVeS is generally well tolerated by patients and shows impressive and convincing cosmetic results.
As the procedure is minimally invasive it leaves virtually no scars.
