The heel raise exercises recommended by airlines as a means to reduce the risk of developing deep vein thromboses (DVT) on long distance flights are also a form of soleus muscle exercise.

Angiography is used to find aneurysms, leaks, blockages (thromboses), new vessel growth, and placement of catheters and stents. Balloon angioplasty is often done with angiography.

Approximately 20% of people with SLE have clinically significant levels of antiphospholipid antibodies, which are associated with antiphospholipid syndrome. Antiphospholipid syndrome is also related to the onset of neural lupus symptoms in the brain. In this form of the disease the cause is very different from lupus: thromboses (blood clots or "sticky blood") form in blood vessels, which prove to be fatal if they move within the blood stream. If the thromboses migrate to the brain, they can potentially cause a stroke by blocking the blood supply to the brain.

Other causes of myonecrosis include envenomation by snakes of the genus Bothrops (family Viperidae), ischemic necrosis, caused by vascular blockage (e.g., diabetes type II), tumours that block or hoard blood supply, and disseminated intravascular coagulation or other thromboses.

Microscopic haematuria and hypertension may also be seen. Stage V can also lead to thrombotic complications such as renal vein thromboses or pulmonary emboli. Class VI, or advanced sclerosing lupus nephritis. a final class which is included by most practitioners.

In SLE, LSE has been linked to pericarditis, presence of anticardiolipin antibodies, arterial and venous thromboses, and neuropsychiatric manifestations of SLE. LSE is associated with greater SLE duration and severity. In some cases, LSE may be the presenting pathology in SLE, especially in the presence of concurrent antiphospholipid syndrome.

PVT is also a known complication of surgical removal of the spleen.Ali Cadili, Chris de Gara, "Complications of Splenectomy", The American Journal of Medicine, 2008, pp 371-375. During the last several years, myeloproliferative neoplasms (MPNs) have emerged as a leading systemic cause of splanchnic vein thromboses (includes PVT).

Superficial venous thromboses cause discomfort but generally not serious consequences, as do the deep vein thromboses (DVTs) that form in the deep veins of the legs or in the pelvic veins. Nevertheless, they can progress to the deep veins through the perforator veins or, they can be responsible for a lung embolism mainly if the head of the clot is poorly attached to the vein wall and is situated near the sapheno-femoral junction. When a blood clot breaks loose and travels in the blood, this is called a venous thromboembolism (VTE). The abbreviation DVT/PE refers to a VTE where a deep vein thrombosis (DVT) has moved to the lungs (PE or pulmonary embolism).

In a study of 189 individuals diagnosed with congenital dysfibrinogenemia, ~33% were asymptomatic, ~47% experienced episodic bleeding, and ~20% experienced episodic thromboses. Due to the rareness of this disorder, treatment of individuals with these presentations are based primarily on case reports, guidelines set by the United Kingdom, and expert opinions rather than controlled clinical studies.

On 28 November 2008, he was elected as the new federal party chairman by 89.6% of delegates at a party conference in Wels. After two thromboses he suffered a pulmonary embolism in March 2011. A few weeks later, on 13 April, he resigned from all political functions. His successor was the Foreign Minister, Michael Spindelegger.orf.

Liver transplantation is an effective treatment for Budd–Chiari. It is generally reserved for patients with fulminant liver failure, failure of shunts, or progression of cirrhosis that reduces the life expectancy to one year. Long-term survival after a transplant ranges from 69–87%. The most common complications of transplants are rejection, arterial or venous thromboses, and bleeding due to the need for anticoagulants.

American evidence-based clinical guidelines were published in 2016 for the treatment of VTE. In the UK, guidelines by the National Institute for Health and Care Excellence (NICE) were published in 2012, updated in 2020. These guidelines do not cover rare forms of thrombosis, for which an individualized approach is often needed. Central and branch retinal vein occlusion does not benefit from anticoagulation in the way that other venous thromboses do.

Warfarin is also used in antiphospholipid syndrome. It has been used occasionally after heart attacks (myocardial infarctions), but is far less effective at preventing new thromboses in coronary arteries. Prevention of clotting in arteries is usually undertaken with antiplatelet drugs, which act by a different mechanism from warfarin (which normally has no effect on platelet function). It can be used to treat people following ischemic strokes due to atrial fibrillation, though direct oral anticoagulants (DOACs) may offer greater benefits.

Carotid artery dissection is thought to be more commonly caused by severe violent trauma to the head and/or neck. An estimated 0.67% of patients admitted to the hospital after major motor vehicle accidents were found to have blunt carotid injury, including intimal dissections, pseudoaneurysms, thromboses, or fistulas. Of these, 76% had intimal dissections, pseudoaneurysms, or a combination of the two. Sports-related activities such as surfing and Jiu-Jitsu have been reported as causes of catorid artery dissection.

A venous thrombosis is a thrombosis in a vein, caused by a thrombus (blood clot). A common type of venous thrombosis is a deep vein thrombosis (DVT), which is a blood clot usually found in the deep veins of the leg. It is increasingly found in the deep veins of the arm, accounting for more than 10% of all deep vein thromboses. If the thrombus breaks off (embolizes) and flows towards the lungs, it can become a pulmonary embolism (PE), a blood clot in the lungs.

In contrast to the understanding for how arterial thromboses occur, as with heart attacks, venous thrombosis formation is not well understood. With arterial thrombosis, blood vessel wall damage is required for thrombosis formation, as it initiates coagulation, but the majority of venous thrombi form without any injured epithelium. Red blood cells and fibrin are the main components of venous thrombi, and the thrombi appear to attach to the blood vessel wall endothelium, normally a non- thrombogenic surface, with fibrin. Platelets in venous thrombi attach to downstream fibrin, while in arterial thrombi, they compose the core.

Since the pseudoaneurysm communicates with an artery through a hole in the arterial wall, a covered stent may be placed endovascularly across this hole to "exclude it," or to prevent it from receiving blood flow from the artery. The covered stent is composed of metal and is covered with polytetrafluoroethylene (PTFE) or another sterile fabric-like material. The covered stent remains in place permanently, and the pseudoaneurysm, without a continuous flow of arterial blood, then thromboses. Advantages of this technique are that it has a high success rate without the need for an open surgery.

Bardsley provided the strong leadership that the Church needed to remain relevant in many peoples' lives that had been disrupted by the War and the long period of austerity that followed. The huge workload that Bardsley undertook started to effect his health and after a visit to Kenya in 1952 he suffered a minor thrombosis necessitating a period in hospital and convalescence. Bardsley was not a man to rest for long and returned to work too early subsequently developing further thromboses and a duodenal ulcer, the intense pain of which reoccurred for the rest of his life. Bardsley was appointed a CBE in the Birthday honours List in 1952.

An abnormality or disease of the platelets is called a thrombocytopathy, which can be either a low number of platelets (thrombocytopenia), a decrease in function of platelets (thrombasthenia), or an increase in the number of platelets (thrombocytosis). There are disorders that reduce the number of platelets, such as heparin-induced thrombocytopenia (HIT) or thrombotic thrombocytopenic purpura (TTP), that typically cause thromboses, or clots, instead of bleeding. Platelets release a multitude of growth factors including platelet-derived growth factor (PDGF), a potent chemotactic agent, and TGF beta, which stimulates the deposition of extracellular matrix. Both of these growth factors have been shown to play a significant role in the repair and regeneration of connective tissues.
