My son is 19 years old and recently diagnosed with a transverse sinus thrombosis. Apparently it has been there for some time as collateral veins have formed. The hematologist we saw indicated his labs were normal and wants to rescan with an MRA/MRV in 6 months.  I guess my main question is, what is the long term prognosis for this type of event? He has a history of Wilms tumor and is now cancer free.  What can we expect in the future? My son is on 325mg of aspirin prophylactic at present. We were told the clot is inoperable and the aspirin is to prevent progression of the clot. Needless to say, we have many questions about prognosis, potential for life-threatening events, etc. Any help or references would be appreciated.
Hi, Thank you for posting your query. Transverse sinus thrombosis is a part of cerebral venous sinus thrombosis, where clotting of blood occurs in the brain veins. I agree with your doctor that it is chronic as collateral circulation has already formed. Firstly, the cause of thrombosis should be found out, as this would decide how long we need to give the anticoagulants. There are some situations such as a thermophilic states, where anticoagulants are required whole life. On the other hand, some factors such as deny Chat Doctor. This condition has good prognosis with treatment. I hope it helps. Please get back if you require any additional information. Wishing you good health,
