  • Improvement of Visceral Arterial Blood Supply after Thoracic Endovascular Aortic Repair for Stanford Type B Aortic Dissection

    ObjectiveTo investigate the improvement of visceral arterial blood supply after thoracic endovascular aortic repair (TEVAR) for patients with Stanford type B aortic dissection (AD). MethodsWe retrospectively analyzed clinical data of 35 patients with Stanford type B AD undergoing TEVAR in Mianyang Central Hospital from January 2013 to March 2014. There were 30 male and 5 female patients with their age of 45-82(62.5±10.0) years. Among the 140 main visceral arteries (celiac artery, superior mesenteric artery, left and right renal arteries) of the 35 patients, blood supply of 79 arteries were compromised, including 36 arteries with stenosis and blood supply via the true lumen, 18 arteries with blood supply via both true and false lumen, 18 arteries with blood supply via the false lumen, and 7 arteries without blood supply. Improvement of blood supply of main visceral arteries was analyzed. ResultsAll the operations were successfully performed without in-hospital death. Operation time was 97.8 (68-147) minutes, length of ICU stay was 12-34 h, and length of hospital stay was 10-21 days. None of the patients had cerebral infarction, acute renal failure, AD rupture or stent migration after TEVAR. Blood supply of the compromised visceral arteries showed improvement in various degrees. ConclusionFor the treatment of Stanford type B AD, TEVAR can not only successfully block the rupture of AD, but also improve blood supply of main visceral arteries, avoid or reduce the complications resulting from compromised visceral arterial blood supply and visceral ischemia.
