Problems and countermeasures for surgical resection of primary pulmonary artery intimal sarcoma

ABSTRACT:

Background

Pulmonary artery intimal sarcoma (PAIS) is a rare but aggressive malignancy. This study clarified the problems and countermeasures of surgical treatment by examining surgical cases of PAIS.

Methods

Between January 2007 and October 2020, 10 patients with PAIS who underwent surgery at our hospital were retrospectively examined.

Results

The surgical procedure that aimed at complete resection was pulmonary resection only (three cases), along with pulmonary artery vascular replacement (six cases) and pulmonary endarterectomy (PE) (one case). The positive rate of vascular stumps was 7/10. In all cases, chest computed tomography scan showed positive margins of ≤20 mm between the tumor and surgical dissection (6/6). In addition, the distance between the locati
