Contralateral pulmonary artery stenosis after left pneumonectomy

Contralateral pulmonary artery stenosis is a rare complication following pneumonectomy. When extensive intrapericardial dissection is warranted, one must be wary of this potential complication and take measures to avoid it. Postoperatively, a high index of suspicion must be maintained in a patient with a new onset of right-sided heart failure after intrapericardial pneumonectomy. We discuss intraoperative risk factors, postoperative clinical findings, and our strategy for repair.
