Right arm ischemia following intentional stent-graft coverage of an anomalous right subclavian artery.

PURPOSE: To report thoracic aortic stent-graft repair in a patient with abnormal aortic arch anatomy.

CASE REPORT: An anomalous right subclavian artery was covered with a stent-graft in a 38-year-old woman being treated for a false aneurysm after coarctation repair. The right arm became relatively ischemic, but was viable and managed conservatively.

CONCLUSIONS

Aneurysms close to left or aberrant right subclavian arteries can be safely and effectively treated by endoluminal repair without the need for revascularization procedures; ischemic symptoms that develop are often mild and transient.
