![]() Alternatively, arterial occlusion occurs as a consequence of embolism of blood clots originating from the heart ("cardiogenic" emboli). Arterial embolism occurs when clots then migrate downstream and can affect any organ. In most cases, arterial thrombosis follows rupture of atheroma (a fat-rich deposit in the blood vessel wall), and is therefore referred to as atherothrombosis. Arterial thrombosis Īrterial thrombosis is the formation of a thrombus within an artery. Staphyloccoal or Streptococcal infections of the face, for example nasal or upper lip pustules may thus spread directly into the cavernous sinus, causing stroke-like symptoms of double vision, squint, as well as spread of infection to cause meningitis. The facial veins in this area anastomose with the superior and inferior ophthalmic veins of the orbit, which drain directly posteriorly into the cavernous sinus through the superior orbital fissure. Ĭavernous sinus thrombosis is a specialised form of cerebral venous sinus thrombosis, where there is thrombosis of the cavernous sinus of the basal skull dura, due to the retrograde spread of infection and endothelial damage from the danger triangle of the face. An arterial embolus may travel further down the affected blood vessel, where it can lodge as an embolism. Complications can arise when a venous thromboembolism (commonly called a VTE) lodges in the lung as a pulmonary embolism. This type of embolism is known as a thromboembolism. A piece of either an arterial or a venous thrombus can break off as an embolus, which could then travel through the circulation and lodge somewhere else as an embolism. Venous thrombosis (sometimes called DVT, deep vein thrombosis) leads to a blood clot in the affected part of the body, while arterial thrombosis (and, rarely, severe venous thrombosis) affects the blood supply and leads to damage of the tissue supplied by that artery ( ischemia and necrosis). Thrombosis may occur in veins ( venous thrombosis) or in arteries ( arterial thrombosis). A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Thrombosis (from Ancient Greek θρόμβωσις thrómbōsis "clotting") is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. ![]() ![]() Vascular surgery, internal medicine, pulmonology Wearing compression stockings for two years after the diagnosis of a DVT reduces the chance of developing post thrombotic syndrome (discussed below).Cyanosis of the lower right extremity, resulting from acute arterial thrombosis of the right leg (on the left side of the image) At Palm Clinic in Auckland, NZ we can fit you for the appropriate compression stockings. The better the flow, the less the chance of a blood clot increasing in size and the less retention of fluid in the tissues. Compression stockings: Compression stockings provide external support to the lower leg, which improves flow within the deep veins.These are only given in a hospital setting. These can have serious side effects such as severe bleeding, and so are only ever used when the benefits outweigh the risks. Thrombolytic drugs: Less commonly, thrombolytic drugs are used to help dissolve the DVT.They can stop an existing clot from getting bigger and thereby reduce the risk of it breaking off and travelling to other parts of the body. Anticoagulants: These are blood thinners which affect the blood’s natural ability to clot.Treatment can vary depending on the size and position of the clot. Treatment at Palm Clinic in Auckland, NZ is aimed at minimising the chance of the clot growing and/or moving to other parts of the body.
