Добавлено (18.05.2021, 23:51) --------------------------------------------- Angiography and UltrasonographyThese forms of imaging are rarely used in the identification of canine heartworm infection outside of referral practices and teaching associations. Angiography is a technique which allows visualization of blood vessels in the body by taking radiographs within seconds after injecting a contrast material (dye) into these blood vessels. In canine heartworm infection, angiography can be used to study changes to the pulmonary arteries. Worms may be visualized on the angiogram as filing defects. Ultrasonography (echocardiography) was utilized to evaluate enlargement of the heart chamber and also to search for the existence of heartworms in the ideal ventricle or main pulmonary artery.Necropsy (evaluation after departure )Although necropsy is probably the most definitive diagnostic evaluation, it's hoped that it never reaches that stage. Heartworms are often found in the ideal ventricle of the heart or in the major pulmonary arteries, at times in its farthest branches. Occasionally heartworms might be seen in organs other than the heart and lungs but such infections are rare. Source: travelgadgetssitez.tumblr.com https://natsuko2point0.tumblr.com/
