Percutaneous placement of a self-expandable stent for treatment of a malignant pulmonary artery stenosis.

Abstract

Venous stent placement is widely accepted as the treatment of stenoses caused by external tumour compression to reduced clinical sequelae. We report percutaneous stent placement into a severely obstructed right pulmonary artery in a 73-year-old female patient. The underlying disease was a medistinal tumour mass of unknown aetiology. Pulmonary perfusion was successfully but temporarily restored by the intervention.

Interventional therapy in sarcoidosis‐associated pulmonary arterial stenosis and pulmonary hypertension

“…IT, BA or SI has already been used to treat pulmonary artery stenosis caused by congenital or malignant pulmonary vascular disease ; however, these treatments are not yet used for the treatment of sarcoidosis related complications. In this study, we used IT for the treatment of SAPH caused by extrinsic compression in sarcoidosis.…”

Endovascular Management of Early Lung Transplant–Related Anastomotic Pulmonary Artery Stenosis

“…Najafizadeh et al (13) later reported similar success with percutaneous transluminal angioplasty with stent placement in a 53-year-old woman without recurrence at 10 months after the intervention. Further experience by several authors demonstrated the safety and efficacy of this technique for treatment of PAS (12,(15)(16)(17)(18)(19). In the long-term, the presence of a stent may complicate a repeat lung transplantation by requiring more extensive dissection further into the hilum to ensure the clamps can be placed beyond the stent and allow for removal of the stent safely.…”

Percutaneous Stenting of Bilateral Pulmonary Artery Stenosis Caused by Malignant Extrinsic Compression

“…The use of a stent endoprosthesis in the PAs has been described in a variety of clinical situations. 2,[5][6][7][8][9][10][11] The main objective has been to avoid vessel recoil, to support the vascular wall in cases of extrinsic compression, 12 and to prevent and treat intimal dissection. The largest experience with stent endoprostheses in the PAs has been seen in children and young adults in whom stents have been used to relieve postsurgical and isolated proximal and distal PA stenosis.…”

“…While clinical improvement has been uniformly noted, it often has been tempered by the underlying disease processes. [7][8][9][10] Complications that have been reported in the literature have included ventricular arrythmias, compromise of arterial sidebranches, 9 intimal flaps and arterial rupture, 3 misplacement and migration of stents, and pulmonary edema. 2,4 In our patient, who presented with right-sided heart failure due to bilateral extrinsic compression of the PAs caused by extensive mediastinal lymphadenopathy due to adenocarcinoma of the lung, there were limited therapeutic options.…”
