Phlebology Knowledge Center

Phlebology is a major branch of medicine that specializes in the diagnosis and treatment of venous diseases.
This increasingly recognized field includes the treatment of varicose veins, deep vein thrombosis and chronic venous insufficiency.
Modern advances in phlebology, such as minimally invasive techniques and improved diagnostic methods, have revolutionized the treatment of venous diseases.

Phlebology is a specialized branch of medicine that deals with the diagnosis and treatment of venous diseases. The term is derived from the Greek words “phlebos” for vein and “logie” for teaching. Although phlebology is a relatively young specialty, it has gained considerable importance in medicine in recent decades. This is mainly due to the increasing number of patients with venous diseases, which can often lead to serious complications if left untreated.

Chronic venous insufficiency (CVI) is a widespread disease of the venous system that affects millions of people worldwide. It is caused by inadequate functioning of the venous valves, which normally prevent the blood from flowing back from the legs to the heart. However, when these valves fail, blood backs up in the veins of the legs, which can lead to increased pressure, swelling and long-term damage such as varicose veins (varicosis), skin changes and even venous ulcers.

CVI develops gradually and is often only recognized in later stages, when symptoms such as swelling, pain or visible varicose veins already appear. People who lead a sedentary lifestyle or have to stand for long periods at work are particularly affected. As the disease is chronic, its progression steadily worsens without treatment. Early diagnosis and the right treatment are crucial to improving the quality of life of those affected and preventing serious complications.

Spider veins are a common aesthetic and medical problem that affects many people. These small, visible veins often appear on the legs and can be caused by various factors. In the following article, we dive deep into the topic to shed light on everything you need to know about spider veins: from their causes, symptoms and diagnoses to the modern treatment options available at VenaZiel Venenzentrum Berlin.

What are spider veins?

Spider veins, also known as telangiectasias, are small, dilated blood vessels that are visible near the surface of the skin.
They appear as thin, bluish or reddish lines that resemble a spider’s web, hence the name “spider veins”.
These veins are often found in areas such as the legs, but also on the face.
Despite their small size, they can become a major aesthetic problem for those affected, often affecting their self-confidence.

Deep vein thrombosis (DVT) is a serious health threat that affects millions of people worldwide. This condition is caused by the formation of a blood clot (thrombus) in a deep vein, often in the lower extremities. An untreated DVT can not only lead to considerable discomfort and functional impairment, but also to life-threatening complications such as a pulmonary embolism. This article is intended to provide comprehensive information on the development, diagnosis and management of deep vein thrombosis, with specific reference to prevention strategies and modern treatment approaches.

What is deep vein thrombosis (DVT)?

Deep vein thrombosis is a condition in which a blood clot forms in a deep vein, usually in the legs or pelvis.
These veins are responsible for transporting blood back to the heart and a thrombus can significantly impede this process.
The clot can partially or completely block the blood flow, causing a range of symptoms and potential complications.

The VenaSeal treatment is a modern, minimally invasive method for treating varicose veins, in which a biological medical adhesive is used to seal diseased veins.
In recent years, this method has proven to be a pioneering alternative to conventional procedures such as vein stripping or thermal ablation (laser or radiofrequency ablation).
The adhesive, which is injected into the affected vein, causes an immediate closure, redirecting the blood to healthy veins.
This not only leads to a significant reduction in symptoms such as pain and swelling, but also to an improvement in the cosmetic appearance.

History and development of VenaSeal

VenaSeal was developed in response to the growing demand for gentler and more patient-friendly treatment options for venous disorders. Traditional methods of treating varicose veins, such as vein stripping or thermal ablation, have proven their effectiveness, but come with disadvantages such as longer recovery times, post-operative pain and the risk of scarring.

Venous diseases are widespread and affect millions of people worldwide. They can range from harmless spider veins to serious problems such as chronic venous insufficiency (CVI) and deep vein thrombosis (DVT). Prevention and treatment of these conditions requires a comprehensive understanding of the factors that influence vein health. In this guide, we will highlight the key issues that contribute to maintaining healthy veins, including diet, exercise, hydration, lifestyle factors and genetic predispositions.

The role of nutrition for vein health

A healthy diet is one of the fundamental pillars of maintaining vein health.
Choosing the right foods can help to promote blood circulation, reduce inflammation and minimize the risk of venous disease.

Ulcus cruris, often referred to as an “open leg”, is a chronic wound that usually affects the lower part of the leg. These hard-to-heal wounds are one of the most common complications in patients with chronic venous insufficiency (CVI). Ulcus cruris is a serious condition that significantly impairs quality of life. In this article, you will learn everything you need to know about the causes of venous leg ulcers, the link to CVI, the connection with other diseases and the latest modern treatment methods such as VenaSeal, radiofrequency ablation and other treatment approaches.

What is a leg ulcer?

 Ulcus cruris is a chronic wound on the lower leg that is difficult to heal and is usually caused by impaired blood circulation. In around 80 % of cases, it is a  Ulcus cruris venosum, which is caused by venous circulatory disorders. Other forms, such as the  Ulcus cruris arteriosum (due to arterial disorders) or the Ulcus cruris mixtum (a combination of venous and arterial causes) also occur, but are less common.

Water retention, also known as oedema, is a common phenomenon that affects many people, especially in summer. This swelling occurs when fluid accumulates in the tissues, usually in the legs and feet. While many cases are harmless and caused by external factors such as heat or prolonged sitting, water retention can also be a sign of serious health problems such as chronic venous insufficiency (CVI) or heart disease. Summer poses a particular challenge for many people with existing venous disease, as the high temperatures increase the risk of swelling and associated discomfort.

This article provides a comprehensive overview of the causes of water retention in the heat, describes preventative measures and explains when a visit to the doctor is necessary. The aim is to provide both laypeople and professionals with well-founded and easy-to-understand information.
