Tough case. This is a pretty rare problem. Without having all the details, I think blood thinners are a must. A good neuro-vascular specialist opinion would be needed.
Can you tell me how to treat a case of basilar artery thrombosis with multiple infarcts. Pt is male 77, dm, ht?
Few options. Not many great options here. Most likely he will need some type of anticoagulation (blood thinners). Should be evaluated by a neurosurgeon with vascular experience.
