[Intraluminal intervention therapy for pulmonary vascular stenosis caused by fibrous mediastinitis:report of two cases].

Fibrosing mediastinitis (FM) is a pathological condition characterized by tissue proliferation and calcification within the mediastinum, leading to the compression of critical structures such as blood vessels and airways. Endovascular intervention is the preferred therapeutic strategy for FM-induced pulmonary vascular stenosis. However, when the disease involves the bifurcation of the pulmonary artery, resulting in stenosis at the origins of both branches, a single-stent implantation cannot simultaneously preserve both vessels. Double-stent implantation is technically more complex than single-stent procedures, but has the advantage of preserving both affected vessels. This article presents two cases of FM-associated pulmonary artery bifurcation stenosis treated with double-stent implantation, with an emphasis on evaluating the therapeutic efficacy and safety of this approach.
