This article examines three instances of UPAA, predominantly affecting the right side, although one case involved the left side. Common characteristics included hemoptysis, observed in two patients\u2014one with a chronic history necessitating embolization and another with a mild, recent onset. The third case was identified incidentally during a preoperative evaluation. All cases demonstrated varying degrees of ipsilateral lung volume reduction and associated interstitial changes or fibrosis. UPAA can be asymptomatic or present with hemoptysis, recurrent infections, or breathlessness. Diagnosis relies on computed tomography pulmonary angiography (CTPA) or magnetic resonance (MR) angiography. Management ranges from observation to embolization or pneumonectomy in severe cases. Mortality is around 7%, with pulmonary hypertension and haemorrhage being major prognostic factors.<\/jats:p>","DOI":"10.1002\/rcr2.70280","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T02:48:36Z","timestamp":1753238916000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Breathing With Half a Pulmonary Circuit: Three Cases of\u00a0Unilateral Pulmonary Artery Agenesis"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6450-982X","authenticated-orcid":false,"given":"Vignesh Kumar","family":"Kathiresan","sequence":"first","affiliation":[{"name":"Department of Pulmonary Medicine Christian Medical College Vellore  Ranipet Campus India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9183-1250","authenticated-orcid":false,"given":"Benjamin Earnest","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Pulmonary Medicine Christian Medical College Vellore  Ranipet Campus India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9303-2428","authenticated-orcid":false,"given":"V.
