Dr Arvind Chandratheva of Queen Square recently explained how he thinks about the potential causes of a stroke.

Let’s assume a patient has had a stroke due to a clot. The clot has originated somewhere in the blood vessel system, which can be thought of as four trees in the winter, two at the front and two at the back and they all come from a root.

When I’m thinking about why and where the clots have come from, I think:

Could it have been a problem in the big trunks, which we call the big carotid or vertebral artery vessels? And we can look for those.

Is it a problem with the little twigs and branches, which we would call a small vessel clot?

Or is it related to the root (or the heart)? Which is what we call a cardio embolic cause.

These are the three areas that we’re looking as a cause for stroke.

Letter to the Queen Square Private Healthcare


I just wanted to say thank you for all the help you gave me during my day in Queen Square recently.  You not only managed to put me at ease, but you managed to get me a last minute appointment with Dr Kapoor, an MRI that evening, and then the results the following day.  I was only in London for a short time so thank you for all that you did for me.
