When can we have next sessions please! 08:33:12 From Maksim Shapiro to Dr. Faust(Privately) : Eric will ask ty 08:33:25 From Maksim Shapiro : Eric will ask ty 08:33:39 From Dr. Amit Sahu : what is ur protocol of 3d dsa for venous sinus evaluation 08:34:14 From Dr. Faust to Maksim Shapiro(Privately) : ok my e-mail is eldocgiov@gmail.com 08:35:01 From Jorge : "what is ur protocol of 3d dsa for venous sinus evaluation?" 08:35:03 From Jorge : +1 08:35:31 From Redmi : How do we distinguish from an anterior sss thrombosis from congenital absence? 08:36:19 From Eric Smith : thanks for clarifying! 08:36:39 From c : Are there any books/sources about an intro to venous sinus embryology that you would recommend for medical students? 08:36:50 From Doortje : but there are nice studies with US showing that IJV should collapse in upright position, and that in NPH this might happen less - but latter is not proven in a large group. 08:36:54 From IGOR PAGIOLA to Maksim Shapiro(Privately) : Do you think there is any relationship between the presence of embryonic tentoral sinuses and the development of dural fistulas like the last case you showed? 08:37:17 From Prateeka Koul : I think part of the venous sinus embryology is connected to the skull anatomy? so variations in skull anatomy would contribute to some variations? 08:37:37 From Ericko Hartanto Laymena : iam sorry, i missed some part of this lecture, can i look it somewhere? Youtube or anything? 08:37:57 From Maksim Shapiro : yes recording will be available thru bananaz page 08:38:35 From Ericko Hartanto Laymena : thank you vey much 08:38:38 From Visish Srinivasan : please see our paper about 3D venous technique: https://pubmed.ncbi.nlm.nih.gov/28820309/?from_term=venous+advanced+srinivasan&from_pos=1 08:38:55 From Dr. Amit Sahu : ok thank you for clarifying 08:39:30 From Jc : “please see our paper about 3D venous technique: https://pubmed.ncbi.nlm.nih.gov/28820309/?from_term=venous+advanced+srinivasan&from_pos=1†thank you 08:39:42 From Henry's iPhone : There is also 4D DSA if you use Siemens 08:40:02 From Bryan Glezerson : What are the best books that you recommend for venous (and arterial) cerebrovascular angiographic anatomy? 08:40:23 From Eytan Raz : Visish that link doesn’t work 08:40:34 From dr.marianovelo@gmail.com : neuroangio.org 08:41:16 From 310408 : inability to understand venous variation and postural change is reason we got into whole CCSVI mess 08:42:09 From Maksim Shapiro : 310408 agree big part of it 08:42:15 From Visish Srinivasan : sorry, try this: https://pubmed.ncbi.nlm.nih.gov/28820309/ 08:42:48 From Ken Wong : also use cross sectional CT and MR 08:42:56 From Visish Srinivasan : essentially, we did it very similarly to how Dr. S described, slight delay, but other details available in paper. 08:45:29 From Srinivasan Paramsivam : What is the importance of Jugular Bulb maturation and why does that happen? 08:47:08 From Maksim Shapiro to francesco biraschi(Privately) : sorry had to mute u for background sound if have a question pls ask or text here thx! 08:47:08 From Bryan Glezerson : Why are most patients right side venous drainage dominant? 08:47:22 From Bryan Glezerson : As a more generalized question 08:48:33 From Dodi Bocc : vena cava is on the right side 08:50:05 From pnelson : Drainage into Right Atrium is more direct through RIJ--SVC 08:50:37 From Dodi Bocc : exact Peter :-) 08:51:20 From Maksim Shapiro : Dodi u want to say something re this? 08:51:24 From Maksim Shapiro : Kim? 08:51:31 From tiborbecske : Beautiful piece of insight! 08:51:44 From tiborbecske : From Dodi and Kim 08:51:59 From Keisuke Yoshida : Postural change of venous drainage pattern is a physiological mechanism to prevent abrupt ICP decrease by venous overdrainage when we get upright. 08:53:09 From Bryan Glezerson : Very astute tautology 08:57:39 From Eytan Raz : Thanks Keisuke, this is a great concept 09:04:04 From tiborbecske to Maksim Shapiro(Privately) : I think the jugular bulb has the function of being a “lake†that dampens the outrush of blood from the head when standing up suddenly 09:04:29 From Maksim Shapiro to tiborbecske(Privately) : interesting! 09:04:46 From Diego Ortega to Maksim Shapiro(Privately) : The Feeder is the lateral or the Marginal tentorial artery? 09:06:36 From Maksim Shapiro to Diego Ortega(Privately) : we call lateral tentorial but I think both names work right? 09:09:51 From Diego Ortega to Maksim Shapiro(Privately) : Thank you, and I really want to say thank you for the Neuroangio.org web for me as trainee is a great educational site. Im from medellin colombia now as NI fellow in Barcelona, hope to meet you at NY. 09:10:13 From Maksim Shapiro : thank you! 09:10:20 From Maksim Shapiro to Diego Ortega(Privately) : thank you! 09:10:39 From Mark Maclean, MD, Canada : Anything you would have done different during 1st treatment 09:10:47 From Kittipong Srivatanakul : Nice case! 09:10:58 From pnelson : Nice Achor variant 09:11:19 From Maksim Shapiro to pnelson(Privately) : :-) 09:12:38 From Maria Luisa : Thanks, very interesting case 09:13:25 From Radiologia Interventistica Ospedale San Giovanni Bosco Torino : Hi Dodi, this is Chiara from Torino. Very interesting case, thank you. What about anticoagulation therapy? 09:15:40 From Boris Pabon to Maksim Shapiro(Privately) : hi my friend , just a question : in a rear view analysis , could you consider the use of two balloons simultaneously?? 09:19:15 From Diego Ortega : what about using a stent instead a balloon assisted embolization? 09:20:36 From pnelson : Except that large balloons are now available. In past larger stents provided an alternative. 09:23:15 From Visish Srinivasan : for my surgical colleagues.... keep this in mind every time you wax off some vein as you're doing a craniotomy! 09:29:21 From Jc : thank you 09:29:44 From Visish Srinivasan : excellent review and discussion today. Thank you! 09:31:38 From Eytan Raz : Thank you Visish for participating 09:32:23 From Boris Pabon : excellent initiative,,, greetings from Colombia 🇨🇴 09:32:29 From Maksim Shapiro to Boris Pabon(Privately) : thank you! 09:32:57 From dr.marianovelo@gmail.com : Have you ever find a diploic DAVF? 09:35:02 From Maksim Shapiro to dr.marianovelo@gmail.com(Privately) : yes we have i think that relates to the "osteodural" concept some really advocate what u think? 09:35:39 From pnelson : sylvian drainage uses a large rostral frontal vein 09:36:27 From Maksim Shapiro to pnelson(Privately) : yes! 09:36:28 From pnelson : superficial MCVs and Labbe correspondingly smaller 09:37:03 From dr.marianovelo@gmail.com to Maksim Shapiro(Privately) : I think the same. 09:38:09 From Kittipong Srivatanakul : Have you ever find a diploic DAVF? >>> Yes, at the base of the skull as we see in ventral epidural shunt in the spine. Some of the hypoglossal canal shunts are actually situated in side the bone. I can show in maybe upcoming sessions. 09:38:16 From Jc : tips and tricks to catheterise the pouch/collector on the occasions is not so approachable? 09:38:56 From Maksim Shapiro : we used a balloon in sinus proper once to deflect microcatheter into that common collector 09:39:12 From Jc : thank you 09:40:17 From Dodi Bocc : very nice 09:42:27 From Dodi Bocc : did you consider putting coils in the vein instead of injecting Onyx? 09:42:58 From esamaniego : The sinus was protected with the balloon. Great case. Very Impressive run from the diagnostic catheter of the sinus pouch. 09:43:20 From Jc : “Very Impressive run from the diagnostic catheter of the sinus pouch.†ideed 09:43:36 From Affan Priyambodo : great sharing. @kittipong cant hardly wait for the case; curious bout symptom and how diganose it 09:45:34 From Dodi Bocc : it underlines the importance of understanding the anatomy, arterial and venous, in these fistulas, always original and different 09:48:45 From esamaniego : Very important to recognize those chanels. 09:52:36 From adrien guenego : thanks a lot !! 09:52:58 From esamaniego : Great cases! Thanks. Edgar 09:53:05 From Miguel Litao : has anyone used iflow feature to identify "common collector"? 09:53:09 From Seon-Kyu Lee : Thanks Max and Eytan for organizing this. I have to go.

Bye from Messina 09:57:22 From Maksim Shapiro to Boris Pabon(Privately) : just keeping pressure under control. if hugely dilated veins probably Kim would advise 09:57:25 From Prateeka Koul : thank you! 09:57:34 From Maksim Shapiro to Boris Pabon(Privately) : kim would advise anticoagulation 09:57:38 From hoyadoc91@gmail.com : Thank you. 09:57:41 From John Jeddore (Memorial Uni) : thank you for your time everyone 09:57:56 From Andrea Rosi : Thank you for sharing! 09:58:16 From Faisal Albader to Maksim Shapiro(Privately) : Thank you, very informative. 09:58:30 From Faisal Albader : Thank you, very informative. 09:58:39 From Ericko Hartanto Laymena to Maksim Shapiro(Privately) : thank you professor, may i see your meningeal vascularization before?
