Pulmonary artery aneurysm secondary to patent arterial duct and infection: A case report and review

Abstract

Pulmonary artery aneurysms (PAAs) are very rare condition. In this paper, we report a case of a twenty‐year‐old female patient with the aneurysm of the pulmonary trunk secondary to the patent arterial duct (PDA) and infection. Diagnosis of PAA was confirmed by echocardiography. The pulmonary artery computed tomographic angiography also revealed the aneurysm and drawn a similar conclusion as echo did. The patient underwent surgery of ligation of PDA and PAA aneurysmectomy repairing with pericardium graft.

Giant pulmonary artery aneurysm in a child: Rare complication of congenital heart disease

“…These observations underscore the importance of considering PAA as a differential diagnosis of hilar masses in patients with both congenital and acquired heart diseases 6 . In areas with limited availability of CT scans, echocardiography can be an essential tool to reach a diagnosis of proximal PAA 9,10 …”

“…6 In areas with limited availability of CT scans, echocardiography can be an essential tool to reach a diagnosis of proximal PAA. 9,10 Currently, there is no agreement on how or when to treat PAA for optimum outcomes, given limited experience from the infrequency of the disease. 3,11 They can be managed conservatively, when possible, by medical treatment targeted at the underlying disease and PAH, especially in patients with CHD, 4,6,7 and radiographic follow-up done with serial echocardiography or CTA.…”

“…The exact disease incidence is difficult to estimate due to the lack of comprehensive studies done in recent years 6 . PAAs can be classified into proximal (central) and peripheral, where the former indicate involvement of the pulmonary trunk or, rarely, the right and left major PAs 4,6,10 . The standard diameter size that defines PAA has varied in the literature from 2.9 to 4.0 cm 5,11 .…”

Left Pulmonary Artery Aneurysm: A Post-stenotic Pulmonary Aneurysm Related to Pulmonary Valve Stenosis

“…Transthoracic echocardiography (TTE) is an important tool to reveal the presence of proximal saccular PAA but has a limited role in evaluating peripheral PAA. CT pulmonary angiography is the gold standard to evaluate the morphology and the location of PAAs and it can also differentiate from other vascular pathologies, such as pulmonary arteriovenous malformation (AVM) [5].…”

Management of Incidental Peripheral Pulmonary Arterial Aneurysm by Interventional Radiology

“…The diagnosis of a PAA is often found incidentally in imaging, but, in suspected cases, pulmonary angiography is the gold standard as it can differentiate PAA from other vascular malformations, including pulmonary arteriovenous malformation (AVM). CT, MRI, and especially echocardiography are other viable, less invasive alternatives [ 4 ].…”
