Eight animals were followed for 1 year, 3 for 4 to 8 weeks, and the remaining 3 for 24 to 48 hours. Aortic specimens were stained with hematoxylin-eosin, elastica-van Gieson, and Masson's trichrome and examined with light and electron microscopy and immunohistochemistry to identify smooth muscle cells (SMC), endothelialization, aortic wall ultrastructure, and changes at the device anchoring sites.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>No dilatation or dissection was noted at any of the device anchoring sites. The aortic media at 1 year was remarkably decreased in thickness: 891 \u00b1 196 \u00b5m in the control tissue versus 388 \u00b1 70 \u00b5m for the proximal stent-grafted aorta and 457 \u00b1 148 \u00b5m for the bare-stented aortic segment. Other important histological features were reduced elastic lamellae in the stent-grafted aorta versus control (p&lt;0.0001), increased SMC density in the stent-grafted aortic region (p&lt;0.0001 versus control), and absence of inflammatory infiltrate. Complete neointimal covering and endothelialization of the luminal endograft surface were found. SMCs generally showed no ultrastructural features of necrosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"conclusions\">\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Aortic stent-grafts induce distinctive histological changes in the aortic wall at 1 year, even when implanted in a healthy aorta. Although there is considerable medial elastin loss, an increased medial SMC density, an exuberant neointima, and a general absence of perigraft inflammation suggest an ongoing process of structural restoration at the device anchoring sites.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/152660280200900311","type":"journal-article","created":{"date-parts":[[2015,3,19]],"date-time":"2015-03-19T06:51:12Z","timestamp":1426747872000},"page":"320-332","source":"Crossref","is-referenced-by-count":10,"title":["Histological Changes in Canine Aorta 1 Year after Stent-Graft Implantation: Implications for the Long-term Stability of Device Anchoring Zones"],"prefix":"10.1177","volume":"9","author":[{"given":"Abul Hasan Muhammad","family":"Bashar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teruhisa","family":"Kazui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Terada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuya","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Washiyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsushi","family":"Yamashita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Baba","sequence":"additional","affiliation":[{"name":"Second Department of Pathology, Hamamatsu University School of Medicine, Hamamatsu City, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2002,6]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1053\/ejvs.1999.0900"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(99)70027-8"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(98)70127-2"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/152660289800500302"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1078-5884(96)80269-3"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/152660289700400105"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(99)70307-1"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/152660280000700608"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1067\/mva.2001.111682"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1067\/mva.2001.111679"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9610(97)00017-2"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(98)70331-8"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.96.7.2438"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1177\/152660280000700607"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(07)61384-0"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1974.01360050092020"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.25.6.677"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.20.1.99"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(84)90083-1"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(93)71905-3"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.1.96"},{"key":"e_1_2_1_23_2","first-page":"993","article-title":"Decreased vascular smooth muscle cell density in medial degeneration of human abdominal aortic aneurysms","volume":"150","author":"Lopez-Candales A","year":"1997","unstructured":"Lopez-Candales A, Holmes DR, Liao S, .
