To reduce risk exercise at least once an hour-getting up and walking or if cant walk then at least ankle flexes or ankle circles and leg bends and flexes; drink lotsof water- for a few days before as well as while on the plane and avoid alcohol. YOU MUST ASK HER DOCTOR, ONLY HER DOCTOR KNOWS HER MEDICAL STATUS. Carotid arteries 70% to 80% may be significant?!

Most cases have at least 3 predisposing risk factors - the risk increases as risk factors increase.

"Very little established research exists in relation to travel. However we do have a wealth of information from hospital research specific to DVT (deep vessel thrombosis...clots). We already know that immobility for an extended period of time can increase the risk of DVT with the following factors being added risk factors:

•Travel for more than 3 hours in the four weeks before and after surgery

•A personal or family history of DVT

•Active cancer or cancer treatment

•Recent surgery or leg surgery

•Existing clotting abnormality

•Obesity (BMI of above 30)

•Chronic or acute medical illnesses

•Hormones or the oral contraceptive pill

•Inflammatory bowel disease

•Varicose veins

•Pregnancy or 2 months post-partum

•Existing Cardiac problems or a history of cardiac problems or stroke

•Dehydration

•Severe infection

•Aged over 60"

To have significant carotid artery may be of some concern as a small clot can easily cause a stroke when it comes in contact with the carotid blockages.
