Embolisation of an acute inflammatory pulmonary artery aneurysm using an Amplatzer(R) vascular plug

Abstract

Pulmonary artery aneurysms (PAA) are rare. To date there are no cases in the literature describing formation secondary to oesophageal perforation. We present an unusual case of ruptured inflammatory segmental PAA.A patient with oesophageal squamous cell cancer presented with shortness of breath and sepsis following endoscopic dilatation of an oesophageal stricture. Imaging demonstrated oesophageal perforation and a pulmonary parenchymal collection containing an inflammatory PAA. Following initial conservative management, he then re-presented with haemoptysis secondary to PAA rupture. He was treated with embolisation using an Amplatzer® vascular plug (AVP) and went on to make an uneventful recovery.

A Rare Case of Peripheral Pulmonary Artery Aneurysm and Cavitating Pneumonia in a Patient with COVID-19 Managed with an Endovascular Method

“…Peripheral PAAs may present with a wide spectrum of sign and symptoms. The patients can be asymptomatic [10] . The pressure effect on surrounding structures may result in nonspecific symptoms [10] such as cough, cyanosis, bronchiectasis, pneumonia, dyspnea [11] , [12] , [13] , [14] , [15] , [16] , [17] , palpitation, hoarseness, and syncopal attacks [18] .…”

Successful embolization of an infected aneurysm of a subsegmental pulmonary artery in an infant with necrotizing MRSA pneumonia

“…Currently, the endovascular approach with coil embolization is preferred as it is less invasive and associated with fewer complications in adults. Amplatzer devices have been successfully used to treat peripheral PAAs as well as arteriovenous malformations in adults and children [6], [7], [8]. In contrast, surgical intervention remains the main therapeutic approach to lesions of the main pulmonary artery.…”

Endovascular coil embolisation of a giant pulmonary artery pseudoaneurysm from a gunshot wound

“…10 Ahmad et al also described the use of the Amplatzer vascular plug for the treatment of an infectious pulmonary artery aneurysm. 11 All these pseudoaneurysms had narrow necks, preventing migration of the vascular plugs. Percutaneous thrombin injection into the pseudoaneurysms sac has also been described in a patient in whom initial coil embolisation had failed.…”
