Historical aspects on the development of angiology in Germany
Insights
Clinical angiology, focused on circulatory disorders, evolved with internal medicine in German-speaking regions. Modern angiology integrates surgical and non-surgical treatments for better patient outcomes.
Area of Science:
- Vascular medicine and circulation disorders.
Background:
- Clinical angiology traditionally focuses on diagnosing and evaluating blood vessel and circulation issues using clinical methods, primarily concerning limb and extracranial arteries.
- Early recognition of peripheral arterial disease (PAD) consequences was limited to severe cases, with angiography enabling correlation between arterial changes and clinical findings.
Observation:
- Initially, both surgeons and internists were interested in angiology, but its establishment in internal medicine was hindered as surgery offered the only promising therapeutic interventions.
- Ratschow's work in German-speaking regions fostered internal medicine's angiology, attracting internists and setting the stage for modern angiology's development.
Findings:
- The 1950s saw the rise of reconstructive arterial surgery, coinciding with advancements in internal medicine-based angiology in German-speaking countries.
- Internist angiologists developed thrombolysis and catheter recanalization (angioplasty), complementing surgical techniques.
- Conservative therapies, including training, vasoactive drugs, rheological methods, and medical prophylaxis, alongside noninvasive diagnostics, were significantly improved.
Implications:
- The current ideal in angiology involves collaborative efforts between internal medicine specialists, reconstructive vascular surgeons, and interventional radiologists.
- This integrated approach aims to optimize the diagnosis and treatment of vascular and circulatory disorders.
Abstract:
Clinical angiology is mainly concerned with vessels and disorders of circulation which can be detected and appraised with clinical methods. The arteries and veins of the limbs as well as the major extracranial arteries supplying the brain are primarily involved. The consequences of a peripheral arterial disease were initially recognized as being due to disorders of blood flow only in their most severe forms. A certain correlation of organic arterial alterations with the clinical finding was first made possible by angiography. Initially, both surgeons and internists directed their attention to this new field. However, since only surgery could offer therapeutic measures promising success, angiology could not become established in internal medicine. Deviating from this general development, Ratschow in Germany and in German-speaking countries and regions was able to create the precondition for an internal medical angiology and to attract the clinical and scientific interest of young internists in this field. The development of modern angiology, which began in the 1950s with the introduction of reconstructive arterial operations hence encountered surgical and internal medical activities in German-speaking countries. In parallel with the improvement in the methods of surgery, the internist angiologists developed thrombolysis and catheter recanalization (angioplasty) into efficient methods of treatment. In addition, the purely conservative techniques of therapy (training, vasoactive substances, rheological methods, medical prophylaxis) as well as noninvasive diagnostics were improved. The ideal concept which is aspired to at present and which has already been put into practice in many places consists in constructive collaboration of internal medical angiology and reconstructive vascular surgery, if possible with the assistance of vessel-oriented radiology.
