Any one who has had a total hip or total knee replacement knows that a major concern after surgery is the formation of blood clots. Blood clots can break loose and travel to the heart or brain causing heart attacks or strokes. Standard postoperative treatment includes prevention of blood clots. In medical terms, this idea is called thromboembolism prophylaxis . One of the tools surgeons rely on the most for blood clot prevention is the use of a low-molecular-weight heparin (LMWH) medication. This drug is a blood thinner more commonly known as Warfarin or Coumadin . Another way to prevent blood clot formation is to avoid any bleeding episodes because that's when the blood forms clots to help stop the flow of blood. Sometimes patients can't be given the prophylactic medication because of the risk of bleeding that comes with using those drugs. Having an alternate treatment approach like compression would be very useful. Right now compression stockings are routinely used after any surgeries ...
Blood clots are the clumps that form when blood hardens from liquid to solid. A blood clot that forms in a blood vessel or in the heart and stays put is called a thrombus. A blood clot that moves to another part of the body is called an embolus and the situation is called an embolism. Blood clots can attach to blood vessels and partially or completely block the flow of blood. When a vein swells because of a blood clot, it's called phlebitis. This blockage stops the usual amount of blood and oxygen from reaching the tissues in that location, which can damage the tissue. Blood clots also can increase your risk of having a stroke. A stroke happens when a blood clot blocks an artery or a blood vessel breaks, interrupting blood flow to the brain.
Symptoms of blood clots include:
warmth and tenderness over the vein
pain or swelling
Certain breast cancer treatments can increase your risk for blood clots. They are:
Avastin (chemical name: bevacizumab), a targeted therapy
The American Academy of Neurology (AAN) is giving us a sneak peek at what's coming up in their annual meeting next month, and new information about Migraine with aura, heart attack, and blood clots is on the agenda.
Two studies on this topic will be presented at the AAN annual meeting in March...
The first study is based on the 15-year-long Women's Health Study, which involved 27,860 women, 1,435 of whom had Migraine with aura. It showed that Migraine with aura is a strong contributor to the development of major cardiovascular events such as stroke and heart attack. During the 15-year study period, there were 1,030 cases of heart attack, stroke, or death from a cardiovascular cause.
Study author Tobias Kurth, MD, ScD, of INSERM, the French National Institute of Health and Medical Research in Bordeaux and Brigham and Women’s Hospital in Boston and a Fellow of the American Academy of Neurology commented:
" After high blood pressure, migraine with aura was the ...
