case_images: (a) Pulmonary artery angiography showing no pass of contrast to the LPA. (b) Selective injection in the proximal LPA shows a tight stenosis (arrow) adjacent to the PDA-device.

case_images: Angiography showed a proximal LPA distortion in relation to the device with a 2.8 mm proximal LPA diameter that increased to 6.1 mm distally (Figure 1).
case_images: (a) Correct position of proximal LPA stent and (b) LPA contrast injection in straight lateral projection showing good angiographic result.

case_images: The final stent diameter was 7.3 mm (Figure 2).
case_images: (a) LPA angiography in straight lateral projection shows severe device related LPA stenosis (arrow). (b) LPA angiography in LAO projection after stenting shows the stent in good position and a good angiographic result.

case_images: Wedged angiography in left upper pulmonary vein (lingular branch) showing the anatomy of the LPA distal to the obstruction. No reflux to the MPA is seen due to complete obstruction of the LPA.

case_images: Wedged angiography in the left lower pulmonary vein showed that the LPA was patent and measured 4 mm at the hilum level, but that it was obstructed by the device at its ostium (Figure 4).
case_images: Final (a) stent position and (b) MPA angiography in cranial-LAO projection showing unobstructed LPA after stenting.
