In this case report, we describe a patient in whom congenital descending aorta coarctation was complicated by subarachnoid hemorrhage secondary to the rupture of a multilevel spinal artery aneurysm, which was treated with endovascular surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case description<\/jats:title>\n                    <jats:p>A 54-year-old man presented with head and neck pain, nausea, and vomiting. He had congenital descending aorta coarctation, which was untreated. Imaging was notable for subarachnoid hemorrhage (SAH) (Modified Fisher grade 3), severe congenital descending aorta coarctation, and multiple aneurysms of the anterior spinal artery and left middle cerebral artery (MCA). One month after external ventricular drainage (EVD) and lumbar drainage (LD), his clinical status gradually stabilized. Owing to the poor general condition and the presence of multiple aneurysms, open surgery was deemed unsuitable, and endovascular treatment was performed. The patient had achieved partial recovery at the15 days operative follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case indicates that foramen magnum SAH with no identifiable source on conventional DSA warrants further investigation via cervical and thoracic myelography, CTA or MRI. Endovascular treatment may be considered for patients with multilevel spinal artery aneurysms and poor surgical candidacy due to frailty.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fsurg.2026.1771342","type":"journal-article","created":{"date-parts":[[2026,2,23]],"date-time":"2026-02-23T06:36:20Z","timestamp":1771828580000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Endovascular treatment of congenital descending aorta coarctation complicated by multiple tandem spinal artery aneurysms: a case report and literature review"],"prefix":"10.3389","volume":"13","author":[{"given":"Chao","family":"Dang","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]},{"name":"Graduate School of Dalian Medical University","place":["Dalian, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"He","family":"Hou","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Chun","family":"Sheng","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun-Yuan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li-Gang","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting-Zhun","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo-Biao","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, General Hospital of Northern Theater Command","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"337","DOI":"10.1016\/j.ccl.2020.04.003","article-title":"Aortic coarctation","volume":"38","author":"Kim","year":"2020","journal-title":"Cardiol Clin"},{"key":"B2","doi-asserted-by":"publisher","first-page":"411","DOI":"10.1007\/s002469900502","article-title":"Congenital heart disease among 815,569 children born between 1980 and 1990 and their 15-year survival: a prospective bohemia survival study","volume":"20","author":"Samanek","year":"1999","journal-title":"Pediatr Cardiol"},{"key":"B3","doi-asserted-by":"publisher","first-page":"285","DOI":"10.1177\/159101990200800308","article-title":"Ruptured anterior spinal artery aneurysm associated with coarctation of aorta.
