Bleeding and Clotting Disorders

Blood clots in sisters

04/17/2007

Question:

My sister and I who are both in our late 30`s have developed sub clavian vein thrombosis with in 14 months of each other, I was diagnosed last year but no cause has been found, are these 2 incidences related? what should we be tested for. we are both healthy and active and not over weight.

Answer:

When we see two family members develop blood clots without precipitating events, we evaluate for inherited disorders leading to increased risk of clotting. These were probably done, but if not, I would ask your primary physician for referral to a physician who sees patients with clotting disorders.
