[Varicose veins: pathogenesis and therapy (author's transl)]

Area of Science:

• Vascular Surgery
• Phlebology
• Anatomy

Context:

• Primary varicose veins are a common vascular condition.
• The etiology of primary varicose veins has been debated.
• Understanding the pathogenesis is crucial for effective treatment.

Purpose:

• To investigate the primary cause of primary varicose veins.
• To evaluate the role of main venous stem valvular lesions.
• To determine the etiological significance of peripheral arteriovenous shunts and perforating veins.

Summary:

• Valvular lesions in main venous stems are the primary cause of primary varicose veins.
• Peripheral arteriovenous shunts are sequelae, not causes, of varicose veins.
• Histological and experimental studies support the role of valvular insufficiency in saphenous veins.

Impact:

• Highlights the therapeutic importance of high saphenous vein ligation.
• Recommends vein stripping and sclerotherapy as optimal treatments.
• Emphasizes avoiding overly radical surgical procedures and outlines treatment risks.
