Ramus Interventricularis Anterior

Anhand eines tierexperimentellen Modells wurde bei insgesamt 12 Hunden untersucht, inwieweit auch kleinere akute intramurale Myokardischämien durch die SPECT nachweisbar sind. Hierzu wurde jeweils der Ramus interventricularis anterior (n = 10) oder der Ramus circumflexus (n = 2) zur Erzeugung von Läsionen der Vorder- und Hinterwand unterbunden. In 10 Fällen erfolgte die Kontrolle durch Transmissions-Computertomographie (TCAT), die in 6 Fällen das Vorliegen von transmuralen und in 4 Fällen von intramuralen Infarkten ergab. Alle Läsionen waren durch die SPECT nachzuweisen (TCAT: 9/10). Da die TCAT nach Kontrastmittelgabe trotz ihrer morphologischen Vorteile (hohe Auflösung) aufgrund hämodynamischer Nebenwirkungen im akuten Infarktstadium nicht eingesetzt werden sollte, bleibt die SPECT hier Methode der Wahl auch für den Nachweis kleinerer intramuraler (akuter) Infarkte.

Ramus Interventricularis Anterior

A fine methacrylate ring (not constricting the artery) was placed around the ramus interventricularis anterior (RIA) of the left coronary artery in dogs. By means of Falck's histochemical technique an extensive degeneration of the vasomotor and cardiomotor adrenergic innervation of ventricles was detected 14 days after the procedure. The innervation of atria remained intact. The surgical intervention as well as the scarring process (which compressed the conducting parts of axons composing the perivascular nerves) induced the degeneration. The results have important implications for experiments with instrumented arteries.

Ramus Interventricularis Anterior

Koroner arter hastalıkları, doğal sebeplerle meydana gelen ölüm nedenlerinin başında gelmektedir. Bu hastalıkların yüksek insidans ve mortalité oranları, bilinen risk faktörlerinden çok, olası risk faktörlerinin araştırılmasını gerekli kılmıştır. Bir fizik muayene bulgusu olan diagonal kulak lobu çizgisi (DKLÇ), 1973 yılında tanımlanmıştır. Çalışmamızda, DKLÇ’nin, ölü muayenesi yapan hekim için ölüm nedeninin tespitinde yardımcı bir bulgu olup olamayacağının saptanması amaçlanmıştır. Çalışmamızın bulguları, vakalara uygulanan anjiografiler sonucunda; a. coronaria sinistranın dalları olan ramus interventricularis anterior (RIA) ve ramus circumflexus (RC) ile a. coronaria dextra’da (ACD) saptanan daralma yüzdeleri arttıkça DKLÇ görülme sıklığının da arttığını göstermektedir. Bu durum DKLÇ ve koroner arter hastalıkları arasmda anlamlı ilişkiler bildiren daha önceki çalışmaların bulguları ile uyumludur. Özellikle öyküye ulaşma olanağı bulunmayan ve herhangi bir travmatik bulgu saptanmayan vakalarda DKLÇ’nin, ölümün koroner arter hastalığından meydana geldiği yönünde destekleyici bir bulgu olarak muayeneyi yapan hekimin dikkatini çekmesi gereken bir işaret olduğunu düşünmekteyiz.Anahtar kelimeler: Diagonal kulak lobu çizgisi, koroner arter hastalığı, ölü muayenesi.

Terminologia Anatomica

Az első anatómiai nómenklatúra, a bázeli „Nomina anatomica” (1895) megjelenésével az anatómiai nevek megalkotásának folyamata nem zárult le, a nemzetközi anatómiai nevezéktan azóta is folyamatos revízió alatt áll. A nevezéktan újragondolását és javítását az új anatómiai struktúrák megnevezése, az archaikus szemléletű nevek megújítása (pl. ramus descendens anterior helyett ramus interventricularis anterior), a már használatban levő nevek hibáinak javítása, a szemlélet egységesítése mellett a más orvosi területekkel, különösen a klinikai ágak nyelvhasználatával való harmonizáció teszi szükségessé. A korábbi kiadásokat következetesség szempontjából felülmúló „Terminologia anatomica” (1998) a különböző orvosi szakterületek terminológiájának egységesítését tűzte ki célul. Az egységes, több terület átfogó anatómiai nómenklatúra létrehozása csak terminológusok, nyelvészek, anatómusok és a klinikai ágak művelőinek szoros együttműködésével valósítható meg.

Ramus Interventricularis Anterior

SummaryExperimental infarctions were produced in 12 dogs by ligation of the Ramus interventricularis anterior of the left coronary artery, and their uptake of 99mTc-heparin was measured 7, 24 and 48 h as well as 7 days thereafter by recording an in vivo chest scintigram 4 h after intravenous injection of the compound. The dogs were subsequently killed, the heart removed and an in vitro scintigram obtained. Finally, the uptake of the compound was measured in tissue samples. The results indicate that 99mTc-heparin is accumulated in lesions which are not older than 24 h. At the other points in time uptake is low but even 24-h old lesions cannot be demonstrated reliably. The results are impaired by the high blood activity on the cardiac chambers and by the background activity of the lungs. In general, 99mTc-heparin has less useful properties than the more frequently employed 99mTc-pyrophosphate so that a change of procedure is not to be recommended.

Ramus Interventricularis Anterior

In 9 dogs a transient myocardial ischemia was provoked using complete occlusion of the ramus interventricularis anterior of the left coronary artery. The occlusion was removed after 5, 10 or 15 min. Four hrs after removal of the occlusion a scan of the myocardium was carried out using 99mTc-labelled pyrophosphate. In 7 out of 9 dogs under study the scan was markedly positive, in 2 dogs negative. ECG demonstrated ischemic changes practically in all dogs; the changes became normal after removal of the occlusion, namely in 5 to 35 min. The histological examination of the tissue demonstrated in all 9 dogs only a slight impairment of the myocardium.
