A couple months ago (during lecture), we had a discussion regarding tPA and acute onset of stroke. As you would expect, we discussed the indications, contraindications, etc of treating stroke with tPA. We also touched on the subject of our role in pushing tPA here at UofL.

Obviously as a stroke center, our stroke team is working around the clock- and as such, generally takes the ball on this one. However, when we are practicing outside of UofL, a stroke team is not always going to be available and ultimately the management will fall on us. Hence the discussion and considerations for us making the call or at least working towards that possibility in the future.

Coincidentally, at precisely the same time as this conversation, a small journal, based out of New England, with a primary focus on medicine, published three fine articles on a similar topic. These articles were focused on the treatment of stroke in  the acute setting.

As pertinent to this post, they explored the use of thrombolysis as well as mechanical removal of thrombus when said thrombus is located in a proximal vessel. Now I won’t pretend I can read, but for those of you who can- below, are links to two “previews” and one complete view of the above mentioned articles. Additionally, an audio file is embedded, containing a break down of the articles by Dr. Dave Newman, of the Mt. Sinai School of Medicine in the Department of Emergency Medicine, to be featured on a future episode of EM:Rap.

Ultimately, I guess the questions I have regarding this as a post on Room9er are as follows:

1. I believe the Stroke team has embraced these articles and to my knowledge (as of February) may have moved towards mechanical retrieval of thrombus in proximal vessels in appropriate candidates. If we are trying to move towards a more ED involved decision tree, what will we need to know and where will our policies stem from? At least as a concept. At this time, I have only heard us discuss tPA, but if we as a hospital are moving towards multiple modalities for treatment of acute stroke, should we not be discussing these as well?

2. With consideration of a 6 hour time frame to thrombus retrieval, what is our (UofL) policy on timelines regarding retrieval. (This is not reflecting any current policies, merely one parameter from one study.)

3. How much time is required from page to cath? This is undoubtedly a big question. What does it take to have a vascular team, NES team, etc ready do go. How will this influence our time of onset to treatment guidelines.

4. Outside of UofL, taking into consideration transit time, etc. how will this influence the management of stroke? Based on CTA availability, transit time, local resources, etc.
