Thank you for this excellent educational video! I am a pulmonologist in Taiwan. The location of left upper lobe (LUL) bronchus in CXR (8:01) and chest CT (8:13-8:17) seemed not match. According to the CT, the LUL bronchus was at or slightly lateral to the level of left pulmonary artery, the major contributing opacity of left hilum in CXR. The actual location of LUL bronochus in CXR may be more lateral to the depicted one at 8:01 in this video.
From wiki bronchial artery, which seems to be omitted on every anatomy course: “The bronchial arteries and their supply of nutrients to the lungs are also attributed to the observation that an occluded (either ligated or by an embolus) pulmonal artery very rarely results in lung infarction.[8] The bronchial arteries can maintain a supply of oxygenated blood to lung tissue.”
The bronchial arteries are tiny and don't account for the opacity visible on CXR. Check my video on the branches of the aorta where I trace out the course of the right and left bronchial arteries: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-l1Kq3WIk0fk.html
@@ThoracicRadiology thanks! I guess my issue is more with that you never hear that a pulmonary embolism doesn’t mean your lung is going to infarct - because the lung has dual blood supply - and in many cases subsegmental PEs are asymptomatic/undetected.
Good day sir. I just want to ask what it means hila and pulmonary vessels are within normal limits? Is it okay or have an effect for applying to work? Thank you
Good morning Dr Rishi, Had gone for a regular checkup. Would very much appreciate if you would give your valued opinion for the same. Is there any way to contact you via email? Thanks.
Dalia Abd. Hilar enlargement can be from a few different reasons. One reason is because of a mass. Sometimes it can be from many enlarged lymph nodes. Another reason is from pulmonary artery enlargement, for example in patients with pulmonary hypertension.
Hi, I can't say for sure in your specific case. There are a lot of reasons why a person might have hilar lymphadenopathy. It is best to ask your doctor and follow their recommendation.
The right pulmonary artery is not something you see in the hilum. By the time the right pulmonary artery reaches the hilum, it has already divided into the right upper lobe branches and the branch supplying the right middle and lower lobes (the interlobar artery).
could mean that they are big, but can't say for sure what it means in your specific case. ask your doc bc they will know more about your specific history.
