Summary
Venous hypertension alone can cause lower leg stasis dermatitis. Surgical treatment of incompetent great saphenous veins successfully healed dermatitis in all patients, with no recurrence after one year.
Area of Science:
- Vascular Surgery
- Dermatology
- Phlebology
Background:
- Lower leg stasis dermatitis is a common condition.
- The role of venous hypertension as a sole cause is debated.
- Superficial venous insufficiency is a frequent finding in patients with stasis dermatitis.
Purpose of the Study:
- To investigate if venous hypertension of the lower leg can independently cause stasis dermatitis.
- To evaluate the efficacy of surgical intervention for superficial venous insufficiency in resolving stasis dermatitis.
Main Methods:
- Retrospective study of 38 patients with lower leg dermatitis undergoing phlebological examination.
- Patch testing for common allergens was performed in 22 patients with superficial venous insufficiency.
- Surgical treatment (flush ligation and saphenectomy) was performed on 10 patients with stasis dermatitis and incompetent great saphenous vein.
Main Results:
- Ten patients with stasis dermatitis and incompetent great saphenous vein were identified.
- Six of these patients had no contact sensitization; four had sensitization to irrelevant substances.
- All 10 surgically treated patients experienced complete healing of lower leg dermatitis within 8-12 weeks, with no recurrence at 1-year follow-up.
Conclusions:
- Venous hypertension due to superficial venous insufficiency can cause lower leg stasis dermatitis.
- Surgical correction of incompetent great saphenous veins is an effective treatment for stasis dermatitis.
- The findings support the hypothesis that venous hypertension alone can be causative of stasis dermatitis.

01:26Varicose Veins I: Introduction
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:30Venous Thrombosis IV: Nursing Management
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
