Plain-English summary
A 9-year-old mixed-breed dog was brought in for breathing problems caused by a large tumor compressing the right pulmonary artery. The veterinarian placed two overlapping stents to relieve the pressure and started chemotherapy to treat the tumor. The dog showed immediate improvement in breathing and has remained symptom-free for five months after the procedure. This combination of stenting and chemotherapy effectively managed the dog's condition.

Abstract
Acquired pulmonary artery branch stenosis without main pulmonary artery involvement due to external compression by neoplasia has been described in human and veterinary medicine. Over time, this can result in right ventricular hypertension and right-sided heart failure. Endovascular stenting offers quick relief from signs, while the underlying cause is addressed. Here, we present a dog with severe right pulmonary artery compression caused by a chemodectoma, which was treated with two, overlapping, self-expanding vascular stents and chemotherapy. The patient experienced immediate symptomatic relief, progressive stent expansion over time, and has been free of clinical symptoms for 5 months post implantation.
