Insights
Incompetent leg perforating veins are not reliable markers of chronic venous insufficiency severity. While more numerous in severe cases, their frequency isn't statistically significant across advanced stages.
Area of Science:
- Vascular Surgery
- Phlebology
- Anatomy
Context:
- Knowledge regarding incompetent leg perforating veins is limited.
- Current assessment methods lack consensus and a gold standard.
- Perforator vein function in healthy individuals can vary.
Purpose:
- To investigate the relationship between incompetent leg perforating veins and chronic venous disease severity.
- To explore the clinical significance and management of incompetent perforating veins.
- To address the lack of consensus on assessing and treating these veins.
Summary:
- Incompetent leg perforating veins are generally more frequent in severe chronic venous disease, but not statistically different in clinical stages 4-6 (CEAP classification).
- Their frequency varies with etiology (primary vs. secondary venous disease).
- Surgical management remains debated, with subfascial endoscopic ligature noted as a promising technique.
Impact:
- Highlights that incompetent leg perforating veins may not be definitive markers of chronic venous insufficiency severity.
- Underscores the need for further research and standardized assessment methods.
- Emphasizes the ongoing debate regarding surgical intervention for these veins.
Abstract:
Our knowledge of the so-called incompetent leg perforating veins remains questionable. Anatomic and hemodynamic studies show that perforators in a healthy subject do not always convey inward flowing blood. Are incompetent perforating veins more frequent with increasing severity of chronic venous disease? Answering this question is difficult as no consensus has been established on how to assess incompetent leg perforating veins and we have no gold standard to refer to. The number of incompetent leg perforating veins is generally greater in severe chronic venous disease although their frequency in clinical stage 4 to 6 (CEAP classification) is not statistically different. This means that incompetent leg perforating veins are not markers of severity of chronic venous insufficiency. When analyzing published series which take into account etiology (primary or secondary venous diseases) the frequency of incompetent perforating veins is variable. Is surgical management required when incompetent leg perforating veins are present? Angiologists and surgeons have not come to an agreement on this point. What can be recommended today? It is generally accepted that the more severe the disease the more worthwhile surgical treatment. Technically speaking, subfascial endoscopic ligature is a promising new method although long-term results are still lacking. We must watch carefully the prospective and randomized studies which have been started in different countries. A lot of questions, only a few reliable answers.
