Surgical repair of giant pulmonary artery aneurysm: a case report
Main Article Content
Abstract
Pulmonary Artery Aneurysms (PAA) are a scarce vascular pathology. They become clinically relevant when their diameter exceeds 5 cm. Weakening of the arterial wall is assumed to be intrinsic, rendering dilation and progression unavoidable. There has been controversy over type of treatment as therapeutic approaches vary, ranging from observation to surgical repair with arterioplasty, pericardial patches, graft interposition and allografts. Surgical repair is performed to reduce complications such as pulmonary embolism, pulmonary hypertension, and aneurysm rupture. Here we present two cases of patients with giant PAA and the type of surgical treatment conducted: in one patient, the affected segment was replaced with a Dacron graft (with pulmonary valve preservation), while the other patient was treated with simple arterioplasty.
