[Varicose veins: pathogenesis and therapy (author's transl)]
Insights
Primary varicose veins stem from valvular lesions in main venous trunks, not peripheral shunts. Treatment focuses on high saphenous vein ligation, stripping, and sclerotherapy for effective management.
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.
Abstract:
Valvular lesions of the main venous stems are regarded as the predominant cause of the formation of primary varicose veins. Peripheral arteriovenous shunts are regarded as sequelae of varicose veins rather than their cause. The perforating and communicating veins are not involved in the pathogenesis of varicose veins. This opinion is supported by the demonstration of insufficiency of the main superficial venous stems in a series of 200 consecutive cases of primary varicosis, even if only the more peripheral veins were dilated. In addition, histological examination of the uppermost valves in the saphenous veins of patients and experimental studies on post-thrombotic vein valves corroborated these views. The therapeutic importance of high ligature of the saphenous veins is stressed. Removal of the dilated veins by stripping is best, but unnecessarily radical procedures should be avoided. A combination of stripping with sclerotherapy is recommended. The dangers of both forms of treatment are outlined.
