PFO Closure has significant impact on Migraine

Posted by iskanbasal on July 19, 2007

I have forgotten it completely, this  association between Migraine and the Patent foramen ovale, PFO. In migraineurs there is a higher probability to find PFO, a cardiac defect or a flap-like opening in the atrial septal wall which is also present in 27% of the general population. I’m aware about the association of PFO and ischemic stroke; PFO cause right to left shunting of venous blood in the heart between the right and left atrium bypassing the lungs. See the opened foramen in this image from the cleveland clinic, see the flux of blood through it. Now the closure of the defect is associated with a more than 50% reduction of migraine headache episodes in patients suffering of migrain. These are results of the trial MIST. PFO closure is performed using the STARFlex septal repair, a catheter-based minimally invasive interventional cardiology procedure.

I have some  interesting reference I got from the primary care neurology society which I would like to keep here for any future interest.

(escuse me english errors).
