Low Pressure Pulmonary Artery Aneurysm with Atrial Septal Defect

Abstract

Pulmonary artery (PA) aneurysm is a rare finding in the thoracic cavity, accompanied by pulmonary hypertension. Clinical presentation of PA aneurysms is usually asymptomatic. The guideline for PA aneurysm treatment is unclear. We report an unusual case of low pressure PA aneurysm associated with atrial septal defect in a 69-year-old man.

A Rare Giant Pulmonary Aneurysm with Left Lung Compression: A Case Report with Insights from the Literature

“…Consequently, some academics [Shankarappa 2010;Galiè 2017] believe that an aneurysm diameter of >4 cm or ratio of aneurysm diameter to body surface area of ≥2.4 cm/m 2 and a PA-to-aorta diameter ratio of >1.5 are more ideal for a diagnosis of PAA. In addition, some scholars considered sex differences and defined PAA as a PA diameter of >43.4 mm in females and >40.4 mm in males or 1.5 times greater than the normal diameter of the PA [Shankarappa 2010;Truong 2010;Kim 2013;Duijnhouwer 2016;Reisenauer 2017]. On the basis of the above diagnosis, Reisenauer et al [Reisenauer 2017] further subdivided PAA into "giant" and "large" pulmonary aneurysms.…”

Huge idiopathic pulmonary artery aneurysm

“…The role of noninvasive imaging modalities such as CT angiography and magnetic resonance angiography is expanding along with the development of image gathering and reconstruction techniques [9] , [10] . Transthoracic echocardiography or transesophageal echocardiography can also detect the PA aneurysm, and both are useful for assessing heart and valvular functions [5] , [11] .…”

Outcome of Surgical Repair of Pulmonary Artery Aneurysms: A Single-Center Experience With 38 Patients

“…P ulmonary artery (PA) aneurysms (PAA) are rare and are noted to occur in 1 in 14,000 patients [1,2]. They are defined as a main PA diameter exceeding 43.4 mm in men and exceeding 40.4 in women [3][4][5][6] or greater than 1.5 times the normal diameter [4] (Fig 1). PAAs may be further classified as high or low pressure by the main PA or right ventricular systolic pressure (RVSP), or both.…”
