Peripheral Pulmonary Artery Aneurysm in a Patient with Limited Respiratory Reserve: Controlled Resection Using Cardiopulmonary Bypass

Peripheral pulmonary artery aneurysm presenting as a solitary pulmonary nodule

“… 2 Solitary peripheral PAA have been managed most often by lobectomy, but occasionally by aneurysmectomy and pulmonary artery repair. 1 , 6 The possibility of endovascular treatment in the present case was considered; however, it was not performed, due to the lack of experience of the radiologists. Rastogi et al 3 recently described a minimally invasive approach to a peripheral PAA.…”

“…The estimated incidence of PAA is 1 in 14,000 autopsies, and these lesions fall into two categories: (1) central aneurysms involving the pulmonary trunk, right or left main pulmonary artery (70%); and (2) peripheral aneurysms that arise from segmental or intrapulmonary branches (30%). 6 An intrapulmonary solitary aneurysm is the rarest form. 1 , 3 - 5 …”

“… 2 Nevertheless, there are enough reports of spontaneous rupture to warrant aggressive surgical treatment, especially in young, healthy individuals. 2 , 4 - 6 …”

Ruptured Pulmonary Artery Aneurysm Mimicking Pulmonary Embolism

“…Idiopathic pulmonary artery aneurysms are extremely rare, and the majority are located in the main pulmonary artery. [1][2][3][4]6,7 They are often associated with congenital cardiac malformations or are caused by degenerative changes, infections or traumas. 1,2,6,8 Peripheral aneurysms usually appear as coin lesions on routine chest radiography, whereas aneurysms of the main artery have the appearance of mediastinal masses.…”

“…Only a few peripheral pulmonary aneurysms have been reported in the literature to date. [1][2][3][4]6,7 The causes of these aneurysms include extensive degenerative changes, traumas, infections (e.g., tuberculosis, syphilis) and congenital malformations. 1,2,6,8 Because of the imminent danger of rupture, treatment should always be surgical.…”
