9 sty 2018 · A study on 36 patients showed that the presence of an avascular pulmonary region or enlargement of the right interlobar pulmonary artery greater than 20 mm with pleural abnormality on CXR had respective sensitivity and specificity of 78% and 92% for differentiating CTEPH from primary pulmonary hypertension .
8 lip 2014 · If the pulmonary artery is enlarged, it presents with an enlarged contour of the vessel below the aortopulmonary window. Transverse diameter of the normal right interlobar artery from its lateral aspect to the intermediate bronchus is 15 mm in women and 16 mm in men.
16 lis 2017 · In both hilae the superior pulmonary vein is the most anterior structure and the inferior pulmonary vein is the most inferior structure. The parenchymal pulmonary vein branches, run within interlobular septa and do not parallel the segmental or sub segmental pulmonary artery branches and bronchi.
3 sie 2024 · In the diagnosis and treatment of chronic thromboembolic pulmonary hypertension (CTEPH), two-dimensional (2D) pulmonary angiography is used. Recognizing the topographic course of the pulmonary arteries and understanding the status in three dimensions (3D) is paramount.
1 mar 2023 · In situ pulmonary arterial thrombosis (PAT) is an underrecognized cause of pulmonary arterial filling defects that has potential important treatment implications. A diagnosis of in situ PAT should be considered in patients with PAT but no DVT in clinical contexts with a plausible biologic mechanism.

Complete renal vascular Doppler assessment involves determining the patency and waveform of the main renal artery and vein; the waveform of the arcuate and interlobar arteries in the upper, interpolar, and lower pole regions; and their associated resistive index (RI).
