Dermatologist,  's  Response
Hello, i would like to know if the patient has been put on blood thinners like warfarin etc., to maintain the patency of the shunts. If so, these petechiae might be a manifestation of the drug overdose, and u may need to consult ur cardiologist for dose adjustment (as per INR). If not on blood thinners, then i would adv you to get a platelet count, bleeding time and clotting time, since there are no constitutional symptoms, it doesnot appear as infective manifestation.
Since the lesions are localised, there is no need to panic, further course of action will depend on the etiology.
Thanks
Take care
