Endoleaks were classified as imperfect proximal seal, flow through fenestrations or branches, or complex (both). Variables studied included coverage of the left subclavian artery, aortic curvature, completeness of proximal apposition, dissection chronicity, and device used. Endoleaks were found during follow-up (mean, 22 months) in 59% of patients, and they were associated with coverage of the left subclavian artery (complex,\n            <jats:italic>P<\/jats:italic>\n            &lt;0.001), small radius of curvature (type 1 and complex,\n            <jats:italic>P<\/jats:italic>\n            =0.05), and greatest length of unapposed proximal stent graft (complex,\n            <jats:italic>P<\/jats:italic>\n            &lt;0.0001). During follow-up, 10 endoleaks resolved spontaneously, 6 required reintervention for false lumen dilatation, and 2 were stable without clinical consequences.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            Endoleaks are common after stent-graft repair of aortic dissection and may lead to false lumen enlargement necessitating reintervention.
