'''Venous ulcers''', often referred to as leg ulcers, are chronic wounds that typically occur on the legs due to malfunctioning venous valves. They represent a significant portion of chronic wound cases and pose a challenge in healthcare due to their persistence and impact on quality of life.
A '''venous ulcer''', also known as a '''stasis ulcer''' or '''varicose ulcer''', is a type of [[chronic wound]] that occurs due to improper functioning of [[venous circulation]], typically in the lower extremities. These ulcers are a common complication of [[chronic venous insufficiency]] and are characterized by open sores that can be painful and difficult to heal.

==Pathophysiology==
Venous ulcers are primarily caused by [[venous hypertension]], which results from malfunctioning [[venous valves]] in the legs. This leads to increased pressure in the veins, causing blood to pool and fluid to leak into surrounding tissues. Over time, this can damage the skin and underlying tissues, leading to ulcer formation.


== Overview ==
==Symptoms==
Venous ulcers are primarily caused by venous insufficiency, a condition where the blood flow through the veins of the legs is inadequate, leading to increased pressure and skin changes.
The primary symptom of a venous ulcer is an open sore on the leg, usually located near the [[ankle]]. Other symptoms may include:
* Swelling in the lower legs
* Aching or heaviness in the legs
* Skin discoloration or changes in texture
* Itching or irritation around the ulcer

==Diagnosis==
title='''{{PAGENAME}}'''
Diagnosis of venous ulcers is typically based on clinical examination. A [[Doppler ultrasound]] may be used to assess blood flow in the veins and confirm the presence of venous insufficiency.

=== Pathophysiology ===
==Treatment==
* The improper functioning of venous valves in the legs causes blood to pool instead of returning to the heart.
The mainstay of treatment for venous ulcers is [[compression therapy]], which helps improve blood flow and reduce swelling. Additional treatments may include:
* This results in increased pressure in the veins, leading to damage and ulcer formation, mostly along the medial distal leg.
* [[Wound care]]: Regular cleaning and dressing of the ulcer to promote healing
* [[Medications]]: Topical or oral antibiotics if infection is present
* [[Surgery]]: Procedures to improve venous circulation, such as vein stripping or endovenous laser therapy


== Prevalence ==
[[File:Úlceras antes da cirurgia.JPG|thumb|Venous ulcers before surgery]]
* Venous ulcers account for 70% to 90% of leg ulcer cases.

* They are more common in older adults, and risk factors include deep vein thrombosis, obesity, and previous leg injuries.


== Symptoms and Diagnosis ==
==Prognosis==
Patients with venous ulcers typically experience:
With appropriate treatment, venous ulcers can heal, although they may recur if underlying venous insufficiency is not addressed. Long-term management may include lifestyle changes, such as weight loss and regular exercise, to improve venous circulation.
* Pain and discomfort in the affected area.
* Swelling and heaviness in the legs.
* Skin discoloration and eczema.


Diagnosis is usually based on medical history, physical examination, and sometimes doppler ultrasonography.
==Prevention==
Preventive measures for venous ulcers include:
* Wearing compression stockings
* Elevating the legs when sitting or lying down
* Avoiding prolonged standing or sitting
* Maintaining a healthy weight


== Treatment and Management ==
==Also see==
The management of venous ulcers includes:
* [[Chronic venous insufficiency]]
* Compression therapy to improve venous blood flow.
* [[Varicose veins]]
* Wound care and dressing to promote healing.
* [[Deep vein thrombosis]]
* Elevating the legs to reduce swelling.
* [[Compression therapy]]
* In severe cases, surgery may be required to address underlying venous insufficiency.
 
== Impact on Quality of Life ==
* Venous ulcers can significantly impact the quality of life due to pain and mobility issues.
* They often require long-term care and can recur if underlying conditions are not managed.

A venous ulcer, also known as a stasis ulcer or varicose ulcer, is a type of chronic wound that occurs due to improper functioning of venous circulation, typically in the lower extremities. These ulcers are a common complication of chronic venous insufficiency and are characterized by open sores that can be painful and difficult to heal.

Pathophysiology[edit]

Venous ulcers are primarily caused by venous hypertension, which results from malfunctioning venous valves in the legs. This leads to increased pressure in the veins, causing blood to pool and fluid to leak into surrounding tissues. Over time, this can damage the skin and underlying tissues, leading to ulcer formation.

Symptoms[edit]

The primary symptom of a venous ulcer is an open sore on the leg, usually located near the ankle. Other symptoms may include:

  • Swelling in the lower legs
  • Aching or heaviness in the legs
  • Skin discoloration or changes in texture
  • Itching or irritation around the ulcer

Diagnosis[edit]

Diagnosis of venous ulcers is typically based on clinical examination. A Doppler ultrasound may be used to assess blood flow in the veins and confirm the presence of venous insufficiency.

Treatment[edit]

The mainstay of treatment for venous ulcers is compression therapy, which helps improve blood flow and reduce swelling. Additional treatments may include:

  • Wound care: Regular cleaning and dressing of the ulcer to promote healing
  • Medications: Topical or oral antibiotics if infection is present
  • Surgery: Procedures to improve venous circulation, such as vein stripping or endovenous laser therapy
Venous ulcers before surgery
Progression of a venous ulcer under treatment

Prognosis[edit]

With appropriate treatment, venous ulcers can heal, although they may recur if underlying venous insufficiency is not addressed. Long-term management may include lifestyle changes, such as weight loss and regular exercise, to improve venous circulation.

Prevention[edit]

Preventive measures for venous ulcers include:

  • Wearing compression stockings
  • Elevating the legs when sitting or lying down
  • Avoiding prolonged standing or sitting
  • Maintaining a healthy weight
