“…The main causes represented in our recent literature review were infective (36.7%), paraneoplastic (31.8%), Swan-Ganz-induced (13.6%), traumatic (9%), post-surgical (4.5%), and iatrogenic (4.5%) [7][8][9][10][11][12][13][14][23][24][25][26]31,32,44,[54][55][56][57][58].…”

“…After diagnosis, three different approaches were followed: a wait-and-see approach, surgical intervention, or endovascular treatment. The "wait and see" approach is rarely considered due to the high risk of rupture of the aneurysmal sac [10] and is probably more suitable in the case of stable PAAs than PAPAs over time.…”

“…PAAs involve all three layers of the vessel wall, while PAPAs involve only the outer layers [3]. PAPAs are associated with a high risk of rupture, and their main infectious causes include fungi, tuberculosis, bacterial pneumonia, septic emboli, and, more recently, COVID-19 [4][5][6][7][8][9][10][11][12][13][14]. Other causes of PAAs and PAPAs include vasculitis, pulmonary hypertension, lung neoplasms, and iatrogenic factors such as cardiopulmonary surgery, radiotherapy, and percutaneous procedures [15,16].…”

The purpose of this bicentric case series was to report the safety, efficacy, and clinical outcome of transcatheter embolization in pulmonary artery pseudoaneurysms (PAPAs). Between January 2016 and June 2021, eight patients with PAPA were subjected to transcatheter embolization. The total number of patients was eight, of which five were female, with a mean age of 62 ± 14 years (average ± standard deviation). Etiology was traumatic in 2/8 cases and iatrogenic in 6/8 cases (after positioning a Swan-Ganz catheter in 5/6 cases and a temporary pacemaker in the latter case). In a single case, the PAPA was incidentally discovered during a routine X-ray, in the remaining 7 cases, the procedure was performed in emergency settings. PAPA embolization was performed using detachable coils alone in 3 cases; coils and glue in 1 case; coils, glue, and vascular plug in 1 case; coils and non-adhesive liquid embolic agents (Onyx and Squid respectively) in 2 cases; and non-adhesive liquid embolic agent alone (Onyx) in 1 case. No peri-procedural or post-procedural complications were recorded. Both the technical and clinical success rates were 100.0%. In conclusion, endovascular embolization is a technically feasible and safe therapeutic option for patients with PAPAs.

“…In nine case reports of PAPs associated with lung abscesses we reviewed [12][13][14][15][16][17][18][19][20], treatments included conservative management (two cases), TAE alone (four cases), surgery alone (two cases), and surgery following TAE (one case) ( M: male, F: female, NR: not reported, TAE: transcatheter arterial embolization, PAPs: pulmonary artery pseudoaneurysms TAE frequently served as the initial treatment approach, aligning with prior literature; however, surgery was also a prominent treatment option. This reflects the complex management and inherent treatment resistance characteristic of lung abscesses.…”

Pulmonary artery pseudoaneurysms (PAPs) are uncommon, yet they frequently result in hemoptysis and are associated with a poor prognosis. We report a case of an 87-year-old male patient. Initially, he was admitted to a previous hospital, and diagnosed with a lung abscess in the left lower lobe. On the second hospital day, he developed hemoptysis. A contrast-enhanced chest computed tomography (CT) identified an infectious pulmonary artery pseudoaneurysm. On the ninth hospital day, pulmonary artery coil embolization was successfully performed, significantly improving the patient's condition.

“…Conservative treatment is mainly applied to non-urgent, asymptomatic cases and may be inadequate in preventing growth or rupture in complex cases (1). In addition, smaller pseudoaneurysms tend to heal by fibrosis on their own (12), and conservative management has been reported to be successful in such cases (3,4,(13)(14)(15)(16)(17)(18)(19)(20). Systemic hemostatic agents may also be effective in decreasing the severity of hemoptysis and possibly reducing the in-hospital mortality of patients with hemoptysis (21,22).…”

Infectious Pulmonary Artery Pseudoaneurysm That Resolved with Conservative Treatment

Pulmonary artery pseudoaneurysms (PAPs) are rare but can cause massive hemoptysis if they rupture. Infectious PAPs are often treated by surgery or transcatheter embolization and are rarely treated conservatively with antibiotics. We herein report a case of PAP treated conservatively in a 21-year-old woman with lung abscess. Except for one massive hemoptysis early in the course, the patient responded well to the empirical therapy with ampicillin/sulbactam and systemic hemostatic agents. After six weeks of antibiotics, the pseudoaneurysm disappeared. Conservative therapy with careful observation can be considered in small infectious PAPs when there is a good clinical response to initial conservative therapy.
