Cytoreductive surgical resection of a rare pulmonary artery intimal sarcoma involving the pulmonary valve and right ventricle: a case report

PMID: 33815748

Abstract

Pulmonary artery intimal sarcoma (PAIS) is an extremely rare malignant tumour. It is often misdiagnosed as chronic pulmonary thromboembolism. We describe a complex case in a 70-year-old man with PAIS extending into his right ventricle undergoing salvage cytoreductive surgical resection utilizing bivalirudin for cardiopulmonary bypass anticoagulation due to heparin-induced thrombocytopenia and thrombosis syndrome. The prognosis for PAIS is extremely poor, with a median survival of 1.5 months without surgical resection. Cytoreductive surgical debulking can improve the median survival time to 17 months. The main aim of palliative surgical resection is to improve ventilation-perfusion mismatch and prevent haemodynamic collapse.
