“…1,2 The true incidence of PAA in patients with PAH remains unclear, given the scarcity of published data. Cabezas and colleagues 3 reported PA diam-eters>40 mm in 48 of 393 (12.2%) group 1 PAH patients. 4 However, giant PA aneurysms (>60 mm) of the pulmonary trunk are extremely rare, and such cases are found in the literature only as anecdotal reports.…”

“…Literature shows that the site of a PA dissection is always at the level of the aneurysm and that the false lumen tends to rupture rather than gradually reexpand, as in a typical aortic dissection [12,13]. In addition, other reports have described a diameter greater than 55 to 60 mm has been associated with left main coronary artery compression, right PA thrombosis, and lung compression atelectasis [14][15][16]. Others have described bronchial compression and collapse, requiring mechanical ventilation [17,18].…”

“…Left main coronary artery compression can result in ischemia-related symptoms. 1,[12][13][14] Given the rarity of this condition, clear and widely recognized treatment guidelines have not been established. 1 Basic recommendations indicate that PAAs less than 50 mm in diameter should be managed conservatively with serial imaging and systemic blood pressure control.…”

Background Pulmonary artery aneurysms (PAAs) are a rare but potentially lethal cardiovascular pathology. PAAs tend to develop in young patients with no gender discrepancy; they are most often associated with congenital heart disorders but also with systemic infections, vasculitis, pulmonary arterial hypertension, chronic pulmonary embolism, and malignancies. Dissection and rupture carry significant morbidity and mortality, thus patients require careful management, especially those with associated pulmonary hypertension. Given the rarity of this condition, physicians have yet to establish standard treatment guidelines. Most studies published to date are case reports with one or two patients; here, we describe our experience with six cases of large PAAs treated surgically at our institution. Methods We identified and retrospectively analyzed clinical data for patients who underwent surgery for PAAs between 2009 and 2017. Results The average age at surgery was 59.73 years, five patients were females, and 83.3% had baseline hypertension. Systolic murmurs were the most common clinical finding. The average aneurysmal size was 65.0 mm. We repaired the PAA with a woven Dacron graft (22‐26 mm) in four patients. We performed concomitant pulmonary valve procedures on five patients: four replacements and one repair. Mean pump and cross‐clamp times were 108.5 and 65 minutes. Operative and 30‐day mortality was 0%. Average length of stay was 10.5 days. Conclusions Postoperative mortality was 0%; all patients showed improvement of symptoms after surgery. These findings confirm that PAA repair has an acceptable risk profile in select patients.
