Venous Thrombosis
Venous thrombosis, manifesting mainly as deep vein thrombosis of the lower extremities and pulmonary embolism, is still under researched and underestimated - F. R. Rosendaal

Unusual Thrombosis
Blood clots most commonly occur in the veins of the lower legs and pelvis (known as deep vein thrombosis or DVT) and the lungs (known as pulmonary embolism or PE). However, thrombosis may occur rarely in unusual sites of the body which can present unique challenges to treatment. For instance, clots can form in the nervous system, abdomen, or organs...
Cerebral Vein Thrombosis
Cerebral vein thrombosis (CVT) is very rare – under 1% of all strokes are due to it. Interestingly, it is more common in women than men – by 3 times. The recommended treatment for CVT is immediate blood-thinner (anticoagulant) medication. Importantly, the chances of another CVT after…

Why Venous Thrombosis Should Always Be Taken Seriously
If you’ve ever been given compression stockings to wear on a long haul flight, you’ve probably been told that it’s to prevent deep vein thrombosis (DVT). But what is venous thrombosis, and why does it pose such a risk?
Catheter-related venous thrombosis
Any time a needle or catheter is put into a vein, the vein wall may become irritated or inflamed, which may lead to the development of small blood clots. Alternatively, the presence of the IV itself can create a spot for blood clots to form.
Causes of venous thrombosis
Venous thrombosis which mainly manifests as deep vein thrombosis of the leg or pulmonary embolism occurs in 1 per 1000 per year. It occurs due to interacting genetic, environmental and behavioral risk factors. The strongest risk factors are certain types of surgery and malignancies. Over the last decade many new risk factors for venous thrombosis have been identified. Venous thrombosis has a high recurrence rate, of around 5 % per year.
Phlebitis: In Some Cases It Is Serious
Phlebitis, which is derived from Greek words for inflammation of a vein, can occur anywhere in the body. The legs are the most common site because when people sit for long uninterrupted periods with their knees bent blood tends to pool. In such circumstances, a clot often forms in a leg vein, and through a mechanism that doctors do not precisely understand an inflammatory reaction develops in the vein. The condition than is called thrombophlebitis.
Venous Thrombosis during Spaceflight
Internal jugular venous thrombosis on Earth is typically associated with cancer, a central venous catheter, or ovarian hyperstimulation; unprovoked isolated venous thrombosis of the internal jugular vein is uncommon. This case of venous thromboembolism in spaceflight highlights unique complexities of space medicine...

Phlebolymphology
The aim of Phlebolymphology is to provide the medical community with updated information written by well-known international specialists, in the form of state-of-the-art articles and original insights into the phlebology and lymphology fields.
Physiopedia
Thrombophlebitis is a circulatory condition that occurs when a blood clot, which developed due to a venous inflammation, inhibits the blood flow. [1] Most commonly, thrombophlebitis affects the superficial veins of the extremities (arms and legs).
ScienceDirect
Factors associated with venous thrombophlebitis, such as vascular damage and hypercoagulability, where initially described by Virchow in 1856. Thrombophlebitis could occur in those undergoing orthopedic, abdominal, lung or breast surgery. It also is associated with cancer, congestive heart failure, sepsis, ulcerative colitis, and nephritic syndrome. The risk of thrombophlebitis is also higher in patients following trauma, such as fractures of the spine and tibia or femur, or with myocardial infarction and/or congestive heart failure. The risk is also increased during the third trimester of pregnancy.
