However, the length of the proximal landing zone remains a limitation, especially with vascular anomalies like an aberrant right subclavian artery (ARSA) posing additional challenges. A 78-year-old patient underwent computed tomography angiography (CTA), which revealed progressive enlargement of a distal aortic arch aneurysm located beyond an ARSA that coursed between the esophagus and trachea. Following evaluation by the multidisciplinary Aortic Team, a hybrid procedure was planned. A right carotid-to-ARSA bypass was performed and a Castor single-branched stent graft (CSBSG) was deployed in the aortic arch with its side branch directed into the left subclavian artery (LSA), thereby covering the origin of the ARSA. To prevent a type II endoleak, plug embolization of the ARSA origin was subsequently performed. CSBSG is a feasible treatment for distal aortic arch aneurysms, even in the presence of vascular anomalies such as ARSA.<\/jats:p>","DOI":"10.3390\/jcdd12070251","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T10:03:48Z","timestamp":1751277828000},"page":"251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Clinical Case of Aneurysmal Dilatation of the Aortic Arch Distal to the Origin of an Aberrant Right Subclavian Artery Treated with Castor Single-Branch Stent Graft Implantation and Right Carotid-Subclavian Bypass"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0755-4933","authenticated-orcid":false,"given":"Antonio","family":"Rizza","sequence":"first","affiliation":[{"name":"Ospedale del Cuore, Fondazione Toscana \u201cG.
