Schenkelsanteil

08:03 Apr 12, 2021 

The Y-stents are designed to fit the anatomical structure of bronchi around the main carina, and so the left limb of the Y-stent branches off at an acute angle from the tracheal limb compared with the right limb.

@ Stuart&Aida, This is very confusing as I find contradicting statements.... but this one https://faculty.washington.edu/jeff8rob/trauma-radiology-ref... , this one http://cardiolatina.com/wp-content/uploads/2020/01/Coronary-... and this one: https://www.wikidoc.org/index.php/Right_coronary_artery seems to indicate that the RMD is located in the middle segment of the RCA.

Regarding Schenkelsanteil . I guess what is meant here is if you imagine RCA and RMD to be two legs (Schenkel = thighs), then the thigh part of the RMD close to the bifurcation from the RCA is occluded.

The bifurcation is located in the middle segment of the RCA , but I guess it needs to be added that the stenting happened in RMD part of the bifurcation (RMD branch).

Abgangsstenose was translated like this here https://www.proz.com/kudoz/german-to-english/medical/17688-a... ... maybe Anne is right in assuming an Y stent but I am inclined to interprete it as a Stenosis at the bifurcation to the RMD.

@Anne I would not think that this is about renewing an existent stent. The doc would have used "Restenose" otherwise. Additionally PTCA is mentioned here .https://www.netdoktor.at/therapie/ptca-8560

Nice to see you here Anne and it is a comfort: Ich verstehe auch nur Bahnhof here :). Good point yours!

Thank you for the explanations and thank you, Uyuni, for explaining that the term Schenkel is somewhat erratic. The problem I see is that the text does only mention Schenkelsanteil which I would also translate as a segment in agreement with Uyuni.

However, I have also found the following:

The segment of the RCA from the ostium to the origin of the first acute marginal artery is usually referred to as the proximal RCA.

https://www.sciencedirect.com/topics/immunology-and-microbio...

Would this imply that the origin of the marginal branch is in the proximal segment according to Thefastshow?

In der Mathematik gilt Schenkel für ‘Winkelseite’ (18. Jh.), nach lat. crūs angulī.

By the way, I also see the difficulty in translating Abgangsstenose and I am perfectly aware of the wonderful coronary anatomy.

Ich verstehe bei diesem kraus formulierten Text ja zugegebenermaßen eher nur Bahnhof - aber der Begriff Schenkel könnte darauf hindeuten, dass hier 2010 ein "Y stenting" oder "V stenting" der RCA am Abgang des RM durchgeführt wurde und jetzt der im RM liegende Schenkel dieser Prothesenkonfiguration am Abgang des RM verstopft ist und neu kanalisiert wurde.

I could not quite figure out in which third the RMD is branching ,whether proximal.or middle part. Hence I gave proximal to middle part...The last link I posted locates it in the proximal part - at least that's how I interprete " Ramus marginalis dexter - ist ebenfalls ein Ast aus dem ersten Abschnitt der A. coronaria dextra und versorgt die vordere Wand des rechten Ventrikels." I would love to find or see more clarifying links regarding the exact location on the RCA. Sorry am on.a bus ,rather difficult....

No bullshit at all!
Glad to see we are in the same scope of coronary anatomy here.

I introduced the term "segment" merely following the (somehow erratic) term "Schenkel" in Pamela's OT. As the RM leaves the main RCA considerably downwards/inferior to its origin I'd prefer "middle" or (perhaps) "intermediate" segment.

Moreover, "proximal" is misleading somehow in the sense of vascular anatomy because the term relates to the centre of the body (this fact often confused even by interventional cardiologists in their cath lab reports). In a stricter sense the word "proximal" (in case of the heart) would point to some region inferior to it and "distal" to some structures cranial to it, as the heart is not the anatomical centre of the human body.

So, our mutual perceptions are only centimeters apart...;-)
Have a nice Sunday!

Check page 8 of this PDF https://semmelweis.hu/anatomia/files/2019/01/Herz2_RT.pdf it will show you the exact location of the ramus marginalis dexter (if this really is the RMD in question).
As uyuni pointed out correctly Abgangsstenose is a stenosis of the bifurcation area https://befunddolmetscher.de/abgangsstenose
Since it branches off the RCA we could talk about a Schenkel since RCA and RMD form an angle. I belief the author meant the stenosis is located where the RMD branches off from the RCA possibly with a tiny fraction of the RMD affected too.

12:43 Apr 11, 2021 

Hm Uyuni I chose proximal because of this "Ramus marginalis dexter - ist ebenfalls ein Ast aus dem ersten Abschnitt der A. coronaria dextra und versorgt die vordere Wand des rechten Ventrikels." https://www.kenhub.com/de/library/anatomie/arteria-coronaria... unless that's bullshit.

"Abgangsstenose" denotes a stenosis which is located right at or within the bifurcation of an arterial branch (here: bifurcation RCA giving off the RM). The latter is anatomically located in the middle - not proximal - segment/section/portion (choice at your discretion...) of the right coronary artery (RCA). "Schenkel" in the OT is not really the correct denotation here as it is merely a part of the RCA without any branches before the first bifurcation...Hope this helps at least a bit.

12:25 Apr 11, 2021 

Can anyone precisely explain what is Schenkel here? How can a Abgangsstenose be found in either the proximal ... or the middle segment of the RCA?

It would help non-native German speakers to understand this a bit more.

BTW, Pamela, let alone various typos there seems to be another flaw in your OT. Left ventricular function is usually measured by EF (ejection fraction). Of course there is a right ventricular EF too but it is very rarely referred to as such. RV function is mostly quantified in terms of the so-called TAPSE (reference values in mm not %).

So my guess is that it must read "LV-Funktion" instead of "RV-Funktion".
