Ib qho ntxiv, qhov sib txawv ntawm AVM thiab AVF yog dab tsi?
Arteriovenous Malformations (Cov AVMs ) thiab AV Fistulas. Arteriovenous malformations (cov AVMs ) yog qhov txawv txav ntawm cov hlab ntsha thiab cov leeg. AV fistulas yog qhov sib txuas tsis zoo nruab nrab cov hlab ntsha thiab cov leeg. Qhov mob no tuaj yeem tshwm sim hauv lub hlwb, npog lub hlwb (dura) thiab tus txha caj qaum.
