Bypass of occlusive lesions can provide durable relief of symptoms with minimal complications. The ideal conduit for carotid-to-subclavian and subclavian-to-carotid bypass remains controversial, and it is not clear whether the outflow vessel influences patency and survival.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods<\/jats:italic>\n            We performed a retrospective analysis of 60 consecutive carotid-to-subclavian and subclavian-to-carotid bypass procedures. Occlusive lesions were documented preoperatively by arteriography. Patency was determined during follow-up by ultrasound or duplex examination. Actuarial patency, symptom-free survival, and overall survival rates were calculated by the life-table method and analyzed by log-rank test.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Results<\/jats:italic>\n            Arterial transposition demonstrated the highest long-term patency rate (100.0\u00b10.0%). Polytetrafluoroethylene grafts demonstrated the highest bypass graft patency rate (95.2\u00b14.6%), followed by Dacron grafts (83.9\u00b110.5%) and saphenous vein grafts (64.8\u00b116.5%). Symptom-free survival paralleled patency rates, but these differences did not achieve statistical significance. While there were no differences in patency or symptom-free survival by outflow vessel, the overall survival of patients with common carotid lesions was significantly lower than that of patients with subclavian lesions (62.7\u00b112.8% versus 100.0\u00b10.0%;\n            <jats:italic>P<\/jats:italic>\n            &lt;.05).\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            The outflow vessel does not affect long-term patency in carotid and subclavian bypass procedures; however, patients with common carotid disease demonstrate significantly poorer long-term survival. Transposition results in superior long-term patency, with a trend toward lower results for synthetic grafts and relatively poor results for autogenous vein grafts.\n          <\/jats:p>","DOI":"10.1161\/01.str.26.9.1565","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:08:03Z","timestamp":1308341283000},"page":"1565-1571","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":84,"title":["Carotid-Subclavian Bypass for Brachiocephalic Occlusive Disease"],"prefix":"10.1161","volume":"26","author":[{"given":"Michael M.","family":"Law","sequence":"first","affiliation":[{"name":"From the Section of Vascular Surgery, Department of Surgery, University of California at Los Angeles School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael D.","family":"Colburn","sequence":"additional","affiliation":[{"name":"From the Section of Vascular Surgery, Department of Surgery, University of California at Los Angeles School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wesley S.","family":"Moore","sequence":"additional","affiliation":[{"name":"From the Section of Vascular Surgery, Department of Surgery, University of California at Los Angeles School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William J.","family":"Quin\u0303ones-Baldrich","sequence":"additional","affiliation":[{"name":"From the Section of Vascular Surgery, Department of Surgery, University of California at Los Angeles School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Herbert I.","family":"Machleder","sequence":"additional","affiliation":[{"name":"From the Section of Vascular Surgery, Department of Surgery, University of California at Los Angeles School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hugh A.","family":"Gelabert","sequence":"additional","affiliation":[{"name":"From the Section of Vascular Surgery, Department of Surgery, University of California at Los Angeles School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(86)90077-7"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1972.03210090019004"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/str.19.4.3284016"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)90002-4"},{"key":"e_1_3_3_5_2","first-page":"643","volume":"54","year":"1988","unstructured":"Moran KT, Zide RS, Persson AV, Jewell ER.
