Successful Aneurysmorrhaphy for a Giant Idiopathic Pulmonary Artery Aneurysm

Abstract

<jats:p> Idiopathic aneurysm of pulmonary artery is a rare disorder with unclear pathology and mechanism. The indications for its surgical treatment are not clear, especially in cases with normal pulmonary pressure. We report the case of a 64-year-old man with a giant idiopathic aneurysm of the pulmonary artery (max diameter 97.3 mm). The patient successfully underwent surgical treatment with the aneurysmorrhaphy in our Department of Cardiovascular and Thoracic Surgery. The patient was extubated successfully within 6 hours of the operation and discharged hospital after 10 days. In cases with giant aneurysm of the pulmonary artery, the aneurysmorrhaphy may be considered as a safe and feasible choice. </jats:p>

Case Report: Surgical management of idiopathic pulmonary aneurysms and review surgical approaches

“…The functionality of the pulmonary valve needs to be evaluated to determine if it is affected. If the valve function is normal and only the annulus is enlarged, a procedure similar to David's ( 16 ) or Devega's ( 15 ) can be performed, preserving as much function of the pulmonary valve as possible; if the valve function is abnormal, a bioprosthetic pulmonary valve is also a good option ( 12 , 18 ) ( Figure 3 ).…”

Management of Giant Pulmonary Artery Aneurysm with Quadricuspid Valve Stenosis

“…20 The scientific literature contains several surgical techniques for pulmonary artery and valve replacements, like a full root homograft, a stentless xenograft root, a biological valved aortic conduit (Bioconduit), or a stented bioprosthesis sewn into a Dacron polyester tube graft. [21][22][23][24] In our patient, we decided to use a Bioconduit for the pulmonary root and valve replacement. Due to the large size of left pulmonary branch, it was impossible to resect the entire aneurysm and we built a conduit with bovine pericardial, sewn afterward on the Bioconduit.…”
