Understanding Chronic Venous Insufficiency
Summary
TLDRThis video educates on chronic venous insufficiency, a condition where blood inefficiently drains from the legs due to vein valve damage. It discusses causes, symptoms like varicose veins and skin changes, and differentiates it from cellulitis. The video also covers management strategies including skin care, improving drainage with weight loss and compression stockings, and treating complications like ulcers and infections.
Takeaways
- 🩹 Chronic Venous Insufficiency (CVI) is a condition where blood doesn't efficiently drain from the legs back to the heart, often due to damaged vein valves.
- 🚶♂️ Causes of CVI include aging, immobility, obesity, prolonged standing, and history of deep vein thrombosis.
- 🔁 Damaged valves impair the leg muscles' ability to pump blood upwards, leading to blood pooling in the veins.
- 🦵 Venous hypertension from blood pooling can cause skin changes, particularly in the 'gaiter' area from the top of the foot to the bottom of the calf.
- 🏿 Hemociderin staining is a red-brown skin discoloration caused by hemoglobin leakage from vessels.
- 🌫️ Venous eczema presents as dry, itchy, flaky, red, and cracked skin due to chronic inflammation.
- 💧 Lipo dermatosclerosis is characterized by hardening and tightening of the skin and underlying tissue, causing a scar-like appearance.
- 🍾 Inflammation can lead to an 'inverted champagne bottle' appearance of the lower legs, narrowing towards the ankles.
- 🏡 Atrophy Blanche is smooth, porcelain-white scar tissue often surrounded by hyperpigmentation, indicating advanced CVI.
- 🩺 Misdiagnosis of CVI skin changes as cellulitis is common; these changes do not improve with antibiotics.
- 💊 Management of CVI involves skin care, improving venous drainage (like compression stockings), and managing complications like infections and ulcers.
Q & A
What is chronic venous insufficiency?
-Chronic venous insufficiency is a condition where blood is not efficiently drained from the legs back to the heart, usually due to damage to the valves inside the veins.
What factors can contribute to the development of chronic venous insufficiency?
-Factors that can contribute include age, immobility, obesity, prolonged standing, or after a deep vein thrombosis.
How are varicose veins related to chronic venous insufficiency?
-Chronic venous insufficiency is often associated with varicose veins, as damaged valves in the veins can lead to blood pooling and vein dilation.
What is the 'gaiter area' in the context of chronic venous insufficiency?
-The 'gaiter area' is the area between the top of the foot and the bottom of the calf muscle, which is most affected by skin changes due to chronic venous insufficiency.
What is hemociderin staining and how does it occur?
-Hemocidoerin staining is a red-brown discoloration caused by hemoglobin leaking out of the vessels into the skin, resulting from the breakdown product of hemoglobin.
What is venous eczema and what causes it?
-Venous eczema, also known as varicose eczema, refers to dry, itchy, flaky, scaly, red, and cracked skin caused by a chronic inflammatory response in the skin.
What is lipodermatosclerosis and how does it affect the skin?
-Lipodermatosclerosis refers to the hardening and tightening of the skin and the tissue beneath the skin, caused by chronic inflammation leading to fibrotic subcutaneous tissue that turns into scar tissue.
What is atrophy Blanche and how does it present on the skin?
-Atrophy Blanche refers to patches of smooth, porcelain-white scar tissue on the skin, often surrounded by hyperpigmentation, which is a feature of chronic venous insufficiency.
What complications can chronic venous insufficiency lead to?
-Complications can include cellulitis or infection in the skin, poor healing after injury, skin ulcers, and pain.
How can chronic venous insufficiency be managed?
-Management involves keeping the skin healthy, improving venous drainage to the legs, and managing complications through weight loss, keeping active, elevating legs when resting, using compression stockings, and treating infections and ulcers.
Why is it important to differentiate chronic venous changes from cellulitis?
-Chronic venous changes are often misdiagnosed as cellulitis, leading to unnecessary antibiotic use. It's important to recognize these changes because they do not resolve with antibiotics and require different management strategies.

🩹 Chronic Venous Insufficiency Overview
This paragraph discusses chronic venous insufficiency (CVI), a condition where blood doesn't efficiently drain from the legs back to the heart, often due to damaged vein valves. This damage can result from aging, immobility, obesity, prolonged standing, or deep vein thrombosis. CVI is commonly linked to varicose veins and leads to venous hypertension due to blood pooling in the legs. The most affected area is known as the 'gaiter area'. Skin changes associated with CVI include hemociderin staining, venous eczema, lipodermatosclerosis, and atrophy Blanche. CVI can also result in cellulitis, poor healing, skin ulcers, and pain. The paragraph emphasizes the importance of recognizing these chronic skin changes in older patients for accurate diagnosis and presentation during medical examinations.
🏥 Management of Chronic Venous Insufficiency
The second paragraph focuses on the management of chronic venous insufficiency. It involves maintaining skin health through monitoring, avoiding skin damage, and using emollients and topical steroids for treatment. To improve venous drainage, the paragraph suggests weight loss for obese patients, staying active, elevating the legs during rest, and using compression stockings after ruling out arterial disease with an ankle brachial pressure index. Managing complications includes administering antibiotics for infections, analgesics for pain, and wound care for ulcers. The paragraph also promotes the Zero to Finals Patreon account for early access to educational content, a comprehensive medicine learning course, digital flashcards, and podcasts to enhance medical knowledge and exam performance.

Highlights
Chronic venous insufficiency occurs when blood is not efficiently draining from the legs back to the heart.
Damage to the valves inside the veins is usually the cause, which may occur with age, immobility, obesity, prolonged standing, or after a deep vein thrombosis.
Chronic venous insufficiency is often associated with varicose veins.
Damaged valves reduce the effectiveness of the leg muscles' pumping action, causing blood to pool in the veins of the legs.
The area between the top of the foot and the bottom of the calf muscle is most affected by skin changes.
Hemocidoerin staining is a red-brown discoloration caused by hemoglobin leaking into the skin.
Venous eczema refers to dry, itchy, flaky, scaly, red, and cracked skin due to chronic inflammation.
Lipo dermatosclerosis is the hardening and tightening of the skin and subcutaneous tissue.
Inflammation of subcutaneous fat is called paniculitis.
Atrophy Blanche refers to patches of smooth, porcelain-white scar tissue often surrounded by hyperpigmentation.
Chronic venous insufficiency can lead to cellulitis, poor healing after injury, skin ulcers, and pain.
Chronic venous changes are common in older patients and are important for OSCE examinations.
Management of chronic venous insufficiency involves keeping the skin healthy, improving venous drainage, and managing complications.
Skin health can be maintained with emollients, topical steroids, and avoiding skin damage.
Improving venous drainage includes weight loss, keeping active, elevating legs, and using compression stockings.
Management of complications involves antibiotics for infection, analgesia for pain, and wound care for ulceration.

ers.com in this video I'm going to be
going through chronic venous
insufficiency and you can find written
notes on this topic at zerodofinos.com
chronic venous insufficiency or in the
vascular surgery section of the zero to
finals surgery book
so let's jump straight in
chronic venous insufficiency occurs when
blood is not efficiently draining from
the legs back to the heart
usually this is the result of damage to
the valves inside the veins
this damage may occur with age
immobility
obesity
prolonged standing
or after a deep vein thrombosis
it's often associated with varicose
veins
the valves inside the veins are
responsible for ensuring that blood
flows in One Direction as the leg
muscles contract and squeeze the veins
when the valves are damaged the pumping
effect of the leg muscles becomes less
effective in draining blood towards the
heart
blood pools in the veins of the legs
causing venous hypertension
chronic pooling of blood in the legs
leads to skin changes the area between
the top of the foot and the bottom of
the calf muscle is the area most
affected by these changes and this is
known as the gator area
hemociderin staining is a red Brown
discoloration which is caused by
hemoglobin leaking out of the vessels
into the skin
hemociderin is a breakdown product of
hemoglobin
venous eczema or varicose eczema refers
to dry itchy flaky scaly red and cracked
skin
these eczema-like changes are caused by
a chronic inflammatory response in the
skin
lipo dermatosclerosis refers to
hardening and tightening of the skin and
the tissue beneath the skin
chronic inflammation causes the
subcutaneous tissue to become fibrotic
turning into scar tissue
inflammation of the subcutaneous fat is
called paniculitis
lipodomatosclerosis causes narrowing of
the lower legs which creates a typical
inverted champagne bottle appearance
which looks like a champagne bottle
that's been turned upside down with very
narrow lower legs that transitioned into
a wider calf and upper leg
atrophy Blanche refers to patches of
smooth porcelain White Scar Tissue on
the skin often surrounded by
hyperpigmentation and this is a feature
of chronic venous insufficiency as well
as well as the skin changes that we've
discussed chronic venous insufficiency
can lead to cellulitis or infection in
the skin
poor healing after injury
skin ulcers
and pain
a Tom tip for you chronic venous changes
are very common in older patients it's
very easy to find patients with these
skin changes to use in Oscar
examinations so it's worth getting
familiar with their appearance and
confidently presenting your examination
findings
these changes are often misdiagnosed as
cellulitis and patients are given causes
of antibiotics
the broken skin and eczema-like changes
do leave patients more prone to skin
infections so infection does need to be
considered but keep in mind that
bilateral cellulitis is quite unusual
and chronic skin changes related to
venous insufficiency will not resolve
with antibiotics
Let's Talk About Management
of chronic venous insufficiency involves
keeping the skin healthy
improving venous drainage to the legs
and managing complications
the skin can be kept healthy by
monitoring the skin health and avoiding
skin damage
regular use of emollients for example
dipra base or laterum citroben or double
bass
topical steroids to treat flares of
venous eczema
and very potent topical steroids to
treat flares of lipo dermatosclerosis
improving venous drainage to the legs
involves weight loss if the patient is
obese
keeping active keeping the legs elevated
when resting
and the use of compression stockings
although arterial disease needs to be
excluded before using compression
stockings using an ankle brachial
pressure index
and finally management of complications
involves antibiotics when infection
occurs
analgesia for pain
and wound care for ulceration
