1Clinical Research Department, Semmelweis University of Medicine, Budapest, Hungary.
Insights
Vein diseases are common, often exceeding arterial conditions. This review surveys recent literature on venous system physiology, focusing on local control mechanisms.
Area of Science:
- Physiology
- Vascular Biology
Background:
- Vein diseases like varicosity and thrombophlebitis have a high incidence, surpassing arterial diseases in some regions.
- The venous system's physiological significance has been historically underestimated but is now being reevaluated due to accumulating experimental data.
Purpose of the Study:
- To critically review recent literature on the physiological functions of the venous system.
- To explore biomechanical, metabolic, and humoral aspects of local venous control.
Main Methods:
- Literature review of selected recent publications.
- Focus on experimental data and physiological parameters related to venous function.
Main Results:
- The review synthesizes current knowledge on venous physiology, highlighting both challenges in data interpretation and the quality of existing research.
- Identifies key aspects of local venous control, including biomechanical, metabolic, and humoral factors.
Conclusions:
- Despite methodological challenges, a significant body of excellent research exists on venous physiology.
- Further accumulation of reliable data is expected to enable a more effective integration of knowledge in this field.
Abstract:
The incidence of vein diseases (varicosity, thrombophlebitis, phlebosclerosis, orthostatic intolerance) is extremely high. In several countries it may exceed that of the arterial pathology by an order of magnitude. In the last decades, this recognition and the rapid accumulation of experimental data have resulted in a progressive reevaluation of the physiological significance of the venous system, which had been rather neglected earlier by scientists. The major aim of this review is to provide a critical survey of recent selected literature related to different physiological functions of the venous system as well as to biomechanical, metabolic, and humoral (ionic, hormonal) aspects of the local venous control. Local neural control mechanisms, including effects of catecholamines and other transmitters, are regarded to be beyond the scope of this work. At present, the synthesis of information available in the literature meets certain difficulties, because occasionally poorly defined methodological techniques and physiological parameters have been applied. On the other hand, a significant part of works dealing with venous physiology is excellent and inspirational. We have good reason to believe that the fast accumulation of reliable scientific data on this very important field will soon reach a new critical level, then an even more effective integration of knowledge will be possible.
