We report a young Indian male with resistant hypertension and bilateral renal artery stenosis, who developed extensive collateral and accessory renal arteries as adaptive vascular remodelling in the setting of chronic, inactive large-vessel vasculitis, with preserved renal function due to extensive collateralisation. This constellation of findings is rare, particularly in males. The case underscores the role of CT angiography in delineating complex vascular remodelling in chronic TA and the importance of early imaging in young individuals with unexplained hypertension.<\/jats:p>","DOI":"10.1136\/bcr-2025-270427","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T13:35:27Z","timestamp":1774532127000},"page":"e270427","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Unusual renal vascular adaptations in childhood Takayasu arteritis: a CT angiographic demonstration of extensive collaterals and aberrant arteries"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1629-7519","authenticated-orcid":false,"given":"Aarosh","family":"Dhamija","sequence":"first","affiliation":[{"name":"Department of Radiodiagnosis and Interventional Radiology, All India Institute of Medical Sciences New Delhi, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8326-0104","authenticated-orcid":false,"given":"Amarinder Singh","family":"Malhi","sequence":"additional","affiliation":[{"name":"Department of Radiodiagnosis and Interventional Radiology, All India Institute of Medical Sciences New Delhi, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,3,26]]},"reference":[{"key":"2026032606351675000_19.3.e270427.1","first-page":"121","article-title":"Current status of Takayasu arteritis in India","volume":"104","author":"Jain","year":"1996","journal-title":"Indian J Med Res"},{"key":"2026032606351675000_19.3.e270427.2","first-page":"25","article-title":"Takayasu\u2019s arteritis: an Indian perspective","volume":"59","author":"Parakh","year":"2007","journal-title":"Indian Heart J"},{"key":"2026032606351675000_19.3.e270427.3","doi-asserted-by":"crossref","first-page":"381","DOI":"10.31138\/mjr.230727.bt","article-title":"Takayasu Arteritis with Severe Renal Artery Stenosis and an Aberrant Renal Artery in a Child: A Case Report and Discussion","volume":"34","author":"Behera","year":"2023","journal-title":"MJR"},{"key":"2026032606351675000_19.3.e270427.4","unstructured":"Lim AY , Lee GY , Jang SY , et al .
