Interstitial pneumonitis following the implantation of a paclitaxel-eluting stent in a patient with peripheral arterial disease

Fig 1. Initial angiography demonstrating chronic total occlusion of the right superficial femoral artery (SFA).

Fig 2. Final angiography after implantation of three paclitaxel-eluting stents (total paclitaxel dose: 1169 μg) in the right superficial femoral artery (SFA), showing successful revascularization. No pseudoaneurysm or dissection was identified.

Fig 3. Computed tomography (CT) angiography revealing a pseudoaneurysm (arrow) at the proximal segment of the right superficial femoral artery (SFA).

Fig 4. A, Preoperative angiography confirming the presence of a pseudoaneurysm (arrow) in the proximal right superficial femoral artery (SFA). B, Postoperative angiography confirmed complete coverage of the pseudoaneurysm by the stent graft and absence of residual contrast extravasation in the right SFA.

Fig 5. Chest computed tomography (CT) showing bilateral ground-glass opacities, predominantly in the peripheral and lower lung zones.

Fig 6. Follow-up chest computed tomography (CT) demonstrating gradual resolution of the previously noted bilateral ground-glass opacities.
