“…Acquired pulmonic stenosis with a similar pathophysiology has been reported in human patients most commonly due to neoplasia (Ozer et al 2009;Badheka et al 2012), but has also been recognised secondary to mediastinal abnormalities (Tardif et al 1994;Satpathy et al 2007;Bulakci et al 2011 differs (in (a) the scale is 5.13 m/s and in (b) the scale is 1.71 m/s) therefore the pulmonary artery peak flow velocity is 4.3 m/s prior to treatment and 1.02 after successful treatment.…”

Summary In the case presented, a young horse was referred for further evaluation based on a presumptive diagnosis of pulmonic valve endocarditis, bronchopneumonia and a cranial mediastinal abscess based on thoracic ultrasound, echocardiography and clinical signs. However, further echocardiographic evaluation revealed that the abscess was compressing the right ventricular outflow track causing outflow obstruction, a murmur associated with right ventricular outflow tract obstruction (acquired pulmonic stenosis) and right ventricular hypertrophy. Vegetative endocarditis was not present. Medical management was unsuccessful, but surgical drainage and long‐term antimicrobial therapy were effective and the horse returned to a successful racing career.

“…Intravascular stents have been used for the management of symptomatic vascular compression, and there are reports in the literature of endovascular stenting for unilateral pulmonary artery stenosis. . The case described is noteworthy in that it is the first described case of bilateral pulmonary artery compression secondary to idiopathic mediastinal fibrosis.…”

Idiopathic mediastinal fibrosis is a rare, histologically benign condition which often presents with symptoms attributable to compression of vital mediastinal structures. Diagnosis can be difficult and individualized treatments are required for patients, with possible intervention including pharmacotherapy, surgery, and percutaneous stenting. We present a case of idiopathic mediastinal fibrosis present in a 50-year-old woman as compression and near obliteration of the pulmonary arteries. A percutaneous approach was utilized with bilateral balloon expandable kissing stents simultaneous deployed from the main pulmonary artery to the right and left pulmonary arteries. There was instantaneous improvement in the pulmonary and systemic hemodynamics. Her immediate postprocedure course was complicated by reperfusion injury to the right lung, requiring intubation and ventilation. The patient made a full recovery and remains well at 6 months. Our case highlights the procedural and postprocedural difficulties that exist in such cases, and reinforces the value of endovascular stenting strategies in the management of patients with this rare condition.

“…Intrathoracic vessel compression secondary to fibrosing mediastinitis has been treated with per-cutaneous stent placement for several years with some success. [9][10][11][12][13][14][15][16][17][18] The flexibility of open-cell design stents was thought to be advantageous for SVC obstruction. However, in-stent stenosis and fibrosis may be a persistent problem for selfexpanding stents.…”

Percutaneous therapy for vessel compression secondary to fibrosing mediastinitis is an option that is effective in improving short-term vascular patency. In-stent stenosis was a frequent complication in patients with fibrosing mediastinitis, particularly when pulmonary veins were involved. Short- and midterm success can be achieved, but progressive fibrosing mediastinitis remains a difficult clinical problem with repeat dilation of stents and/or additional stent placement necessary to maintain optimal stent patency and improvement in clinical symptomatology.
