Clementine Posted September 4, 2017 Hi All! My last CT scan shows a dilated pulmonary artery. In 2005 it was 30mm and in 2015 it was 35mm. At the time I also had an ECHO which was unremarkable. I am preparing for an upcoming appointment, with the same tests, and wanted to see what you all think. How concerned should I be? I have systemic sine sclerosis with ILD. Thank you.

dimarzio Posted September 4, 2017 Using unenhanced axial 10 mm CT sections, the upper limit of normal main pulmonary artery diameter is 3.32 cm. Pulmonary arterial hypertension should be considered in patients with values above this level. Share this post Link to post Share on other sites
Joelf Posted September 4, 2017 Hi Clementine, How lovely to hear from you again and I'm sorry that you're having concerns about a dilated pulmonary artery. Apart from an out of date first aid certificate, I've no medical training, so can't really advise you, but pulmonary hypertension cannot be diagnosed without a right heart catheterisation and it sounds like you'll be having other tests as well, to help with any diagnosis. I can understand that you're feeling a bit anxious about your upcoming appointment and I do hope that your consultant will be able to help and advise you.

Clementine Posted September 5, 2017 Thank you! I really think it's nothing since my ECHO was normal. I just worry like crazy and it's been two years since I've had one. Hopefully I won't need the right heart catheterization. I've had one and feel they are a piece of cake, but time and money. If anyone else has anything to add, please do so. I don't like having it dilated and assume it could be worse now. Thanks. ❤️ Share this post Link to post Share on other sites
