“…[10] This device has been successfully used in the pulmonary arteries in Behçet's disease, Hughes-Stovin syndrome, iatrogenic PA aneurysms, idiopathic aneurysms and pulmonary arteriovenous malformations (AVMs), among others. [11][12][13] However, to our knowledge this is the only series of Rasmussen aneurysms managed with the AVP to date.…”

Rasmussen aneurysms are abnormalities of the pulmonary arterial system caused by tuberculosis (TB). They are associated with a highmortality rate when they cause life-threatening haemoptysis. High TB-prevalence regions have a large burden of TB-related haemoptysisbut often limited resources. This series of 25 patients who presented with life-threatening haemoptysis from current and/or previous TBwere found to have abnormal pulmonary arteries on computed tomography pulmonary angiogram (CTPA), which were judged to belikely contributors to their bleeding, either in isolation or with concomitant abnormal bronchial or systemic vasculature. These patientsunderwent transcatheter placement of Amplatzer vascular plugs in the feeder pulmonary artery. Bronchial and systemic lesions wereaddressed separately as needed. Immediate technical success was achieved in all patients, but four of them experienced intraoperativehaemoptysis related to dislodgement of the occluding platelet plug by the high-pressure automatic injector and wire. At 48 hours after theprocedure, 18 (72%) remained haemoptysis-free. Six of these experienced recurrence within 1 year of their procedure. Pulmonary arteryplacement of an Amplatzer vascular plug is a feasible option for treating bleeding Rasmussen aneurysms, but should be part of a combinedapproach to addressing suspected culprit vascular lesions in all intrathoracic vascular systems.

“…Transcatheter embolization is a less invasive treatment than surgery for idiopathic peripheral PAAs. There are only 2 reports of transcatheter embolization of unruptured idiopathic peripheral PAAs: one report of embolization of the aneurysm alone with coils, and the other report of embolization with vascular plugs distal to the aneurysm and coils within and proximal to the aneurysm, both with good clinical outcomes [3 , 4] . In the present case, the area distal, within, and proximal to the PAA was embolized with coils, and complete embolization was achieved without complications.…”

“…Among acquired aneurysms, those without a history of secondary PAAs, such as pulmonary hypertension, connective tissue abnormalities, vasculitis, or trauma, are classified as idiopathic PAAs [2] . Idiopathic peripheral PAAs are very rare, and there are few reports of transcatheter treatment [3 , 4] . In this report, we present a case of transcatheter embolization of idiopathic peripheral PAA.…”
