Exposure to Air Pollution May Affect Pulmonary Circulation

FRIDAY, June 7, 2019 -- Long-term black carbon exposure is associated with a larger peripheral total pulmonary vascular volume measured on noncontrast chest computed tomography (TPVVCT), according to a study published in the June 1 issue of the...

Editor ’s PerspectiveWhat We Already Know about This TopicAfter pulmonary artery occlusion (mimicking a pulmonary embolism), perfusion is redistributed to the rest of the lung tissue, but the distribution of ventilation is uncertain.What This Article Tells Us That Is NewData from anesthetized pigs (uninjured lungs) indicate that the perfusion is redistributed as suspected. Similarly, ventilation is redistributed from nonperfused to perfused lung tissue. This limits the increase in dead space and is accompanied by less density in the occluded lung.Background Acute unilateral pulmonary arterial occlusion causes ventila...

Authors: Schuurmann RCL, de Rooy PM, Bastos Gonçalves F, Vos CG, de Vries JPM Abstract Introduction: Although there is much attention for proper sizing of pre-operative anatomy before (thoracic) endovascular aneurysm repair ([T]EVAR), standardized assessment of endograft position and apposition at post-operative imaging is seldom addressed in the international guidelines. The highly detailed three-dimensional computed tomography angiography (CTA) volumes contain valuable information about the apposition of the endograft with the arterial wall and the position of the device relative to anatomical landmarks in...

Conclusion Revascularization of a diffusely diseased LAD using the off-pump LIMA onlay-patch technique results in encouraging clinical outcomes with favorable angiographic results. Concomitant LAD endarterectomy and intraoperative LIMA graft flow are associated with the risk of postoperative LIMA graft failure.

CONCLUSIONS: Accuracy of CT scan for identification of pT3/4, pN+, or extramural venous invasion was insufficient to allow for proper identification of patients at high risk for local recurrence and/or in whom to consider alternative treatment strategies. Locoregional overstaging and understaging resulted in inappropriate treatment strategies in
