A cikin 'yan shekarun nan, ƙarin haƙiƙa kimanta girman atrial na hagu domin manufar Girman Atrial Hagu na Vertebral (VLAS) Hanyar da ake kira cardiomegaly (ƙaramar zuciya) kuma musamman girman atrium na hagu (hagu atrium) tsara don ƙarin madaidaicin kimantawa.
Menene VLAS?
VLAS, auna girman atrium na hagu (LA) ta amfani da tunani na vertebral ma'auni ne wanda ke bayarwa. Ana amfani da wannan hanyar a cikin karnuka hagu atrial girma don ƙayyade da farkon gano cutar mitral valve (MMVD) ko wasu cututtukan zuciya Baya ga ma'aunin VHS na gargajiya (Vertebral Heart Score), VLAS yana ba da damar ingantaccen kimantawa na hagu atrium na zuciya.
Yaya ake auna VLAS?
Laterolateral (gefen dama) x-ray ana amfani da tsinkaya. Ana yin ma'aunin a cikin matakai masu zuwa:
1. An ƙaddara wurin farawa:
• Carina (bifurcation na trachea - batu na rabuwa zuwa biyu) Wannan shine batu akan x-ray inda trachea ta raba zuwa manyan mashako guda biyu.
2. An ƙaddara ƙarshen batu:
• Mafi caudal (baya mafi girma) na iyakar iyaka (kwankwasa na baya) na atrium na hagu Wannan yawanci ana ƙaddara ta zagayawa mai zagaye a bayan kasan ɓangaren babban ɓangaren hagu ana gani kamar.
3. Ana yin aunawa:
Ana auna nisa tsakanin waɗannan maki biyu (daga carina zuwa iyakar caudal na atrium na hagu).
4. Juyawa zuwa naúrar ma'aunin vertebral:
• Wannan nisa, An juyar da kashin baya na 4th (Th4) zuwa sashin kashin baya gwargwadon tsayinsa.Wato ana lissafta adadin kashin baya nawa ne wannan nisa ya yi daidai da Th4.
Mahimmancin VLAS na al'ada a cikin karnuka
• Babban iyaka na al'ada: 2,4 kashin baya
• Idan VLAS Idan ya fi girma fiye da 2,4, wannan hali dilatation na hagu (hagu atrium enlargement) ana kimanta kamar.
• Mahimman iyaka: 3,0 kashin baya (bisa ga jagororin ACVIM)
• ACVIM (Kwalejin Nazarin Dabbobin Cikin Gida na Amurka) jagororin, Cutar Mitral Valve (MMVD) mataki B2 a matsayin ma'auni don VLAS> 3,0karba.
• Sai dai a cewar wasu masana. Iyakar 3,0 ya yi girma da ƙima Wannan ƙimar, yayin da takamaiman, yana da ƙananan hankali. Wannan yana nufin cewa yawancin lokuta na haɓakar hagu na hagu bazai iya gano su a wannan bakin kofa ba.

VLAS, musamman cututtukan zuciya da ke haifar da haɓakar atrium na hagu Yana da mahimmanci don ganewar farko na irin waɗannan cututtuka.
Babban cututtukan da ke haɓaka VLAS sune::
• Cutar mitral bawul (MMVD): Girma yana faruwa saboda tarin jini a cikin atrium na hagu.
• Dilated cardiomyopathy (DCM)Hagu haɓakar hagu yawanci kuma yana ƙara girman atrium na hagu.
• Hypertrophic cardiomyopathy (HCM) (a cikin kuliyoyi): Girman atrium na hagu ya zama ruwan dare saboda kauri na bangon ventricular na hagu.
• Ciwon zuciya arrhythmias: Zubar da jini a cikin atrium na hagu yayin arrhythmias na iya haifar da girma.
• Ciwon zuciya na yau da kullun (CHF)Rashin raunin zuciya na yau da kullun yana haifar da karuwar bugun bugun jini na hagu, yana haifar da haɓaka atrium na hagu.
Muhimmancin Clinical na VLAS
1. Ciwon Mitral Valve (MMVD) Matsayi:
• VLAS> 3,0, "Mataki na B2" a cikin jagororin ACVIM Wannan yana nufin a fara magani.
• Duk da haka, wasu masana. Darajar fiye da 2,4 yana ba da shawarar tsoma baki a baya, tare da la'akari
2. Ganewar Farko:
• VLAS, zai iya gano haɓakar bugun jini na hagu a farkon mataki, saboda VHS kawai tana tantance girman girman zuciya.
3. Biyan Magani:
• Bayan fara jiyya, ana sake auna VLAS. Idan VLAS ya ragu, wannan yana nuna cewa maganin yana aiki.
4. Ƙimar Haƙiƙa:
VLAS yana ba da ma'auni na haƙiƙa mai zaman kansa ba tare da kimantawa na zahiri ba. Wannan yana ba da damar asibitoci don samun ƙarin sakamako mai ƙima.
• VLAS, kawai tantance girman atrium na hagu Ma'auni ne na haƙiƙa.
• Aunawa, nisa tsakanin bifurcation na tracheal da iyakar baya na atrium na hagu kuma ana yin wannan nisa ta amfani da shi An ƙididdige shi bisa girman girman kashin thoracic na huɗu.
• Babban iyaka na al'ada: ≤ 2,4 kashin baya.
• ACVIM jagora, don ciwon mitral bawul VLAS> 3,0bukatar magani B2 lokaci yarda da shi.
• Ana amfani da VLAS a farkon ganewar asali na kara girman zuciya, bibiyar cutar da fara magani da wuri amfani don.
Wannan hanya tana ba da babbar fa'ida don farkon ganewar cututtukan cututtukan zuciya kuma yana ba da damar fara farawa da wuri na jiyya don cututtukan mitral valve (MMVD).
