Clinical notes, laboratory data and imaging were reviewed.\nResults: The overall complication rate was 6.8%, with no Clavien-Dindo grades III\u2013V complications. Kidney function was unaffected by embolisation as measured by creatinine. Median radiological follow-up was 4.8 years (interquartile range [IQR]: 2.8\u20137.8), and median clinical follow-up was 7.5 years (IQR: 4.7\u201314.0). Decreasing AML size was observed in 96% of procedures. Maximal shrinkage (30% median diameter decrease; IQR: 15\u201344) was reached after median 2.2 years (IQR: 0.6\u20134.8). During follow-up, regrowth occurred in 38% of patients, and four bleeding episodes occurred in three patients with tuberous sclerosis. Growing size and\/or rebleeding prompted a redo embolisation in 9% of spontaneous AML and 50% of tuberous sclerosis-associated AML.\nConclusions: Being a well-tolerated treatment with few complications, selective arterial embolisation renders a pronounced size-reduction in most patients with AML, and kidney function is preserved. Regrowth is common, and a radiological follow-up is necessary. Tuberous sclerosis is a risk factor for the need of reintervention.<\/jats:p>","DOI":"10.2340\/sju.v58.12318","type":"journal-article","created":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T12:47:57Z","timestamp":1698756477000},"page":"86-92","source":"Crossref","is-referenced-by-count":11,"title":["Long-term efficacy of selective arterial embolisation of renal angiomyolipoma"],"prefix":"10.2340","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6035-6381","authenticated-orcid":false,"given":"Jesper","family":"Sw\u00e4rd","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karl","family":"Bohlin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olof","family":"Henrikson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Lundstam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralph","family":"Peeker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Grenabo Bergdahl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2023,10,31]]},"reference":[{"key":"40584","doi-asserted-by":"crossref","unstructured":"Fittschen, A., I.
