What exactly was this complication? Is there anything we should know about this?
The complication was a combination of a rare type of clotting disorder called a cerebral sinus venous thrombosis and a low platelet count.
It is important to note that this is different from the regular blood clots we are used to thinking about. In this case, the blood clot is the result of an immune-mediated phenomenon that causes destruction of the platelets (clotting cells) but also causes production of clots itself.
The typical risk factors for blood clots are NOT associated with this type of clots.
