EBUS-DSA hybrid guidance for complex pulmonary artery stenosis stenting in fibrosing mediastinitis
Original Abstract
<span class="paragraphSection">An 82-year-old male presented with a 3-year history of fibrosing mediastinitis and progressively worsening dyspnea. Computed tomography angiography revealed bilateral hilar soft tissue calcifications, right upper lobe consolidation, and multifocal pulmonary artery stenoses (<a href="#aamaf062-F1" class="reflinks">Figure 1A-C</a>), most pronounced in the left lower pulmonary artery near the origin of the A4/A5 common trunk (<a href="#aamaf062-F1" class="reflinks">Figure 1D</a>). Right heart catheterization confirmed precapillary pulmonary hypertension with a significant transstenotic pressure gradient: proximal measurements were 56/7 mmHg (mean pulmonary artery pressure [mPAP], 27 mmHg), while distal measurements were 24/6 mmHg (mPAP 13 mmHg).</span>
