To examine the fate of the renal ostia following transrenal fixation of endovascular aortic stent-grafts.
Methods:
Thirty-five patients (29 men; mean age 75 years) undergoing endovascular repair for abdominal aortic aneurysms (AAAs) had transrenal fixation of the uncovered proximal stent due to a short (<1.5 cm long) or conical neck or a periprocedural endoleak. Eighteen (51%) patients were hypertensive; 7 (20%) had renal artery stenoses (RAS). Outcome measures included blood pressure, serum creatinine, computed tomography, and renal artery duplex scans.
Results:
Two patients with ≥60% RAS had renal stents placed during the endograft procedure; the other 5 RAS patients were normotensive and their renal lesions were not treated. Overall technical success was 82.9% (29/35). One (2.9%) case was converted due to graft twisting. There were 5 (14.2%) early endoleaks. Transient postoperative creatinine elevations were observed in 5 (14.2%) cases.
Over a median 11-month period (range 2–24), no secondary endoleaks or silent renal artery occlusions were seen. One normotensive patient with an untreated ≥60% renal lesion developed hypertension and severe stenosis (99%) at 4 months; stenting through the interstices of the transrenal stent was performed. No disease progression was seen in the other 6 RAS patients.
Conclusions:
In the intermediate period, transrenal fixation appears to have no adverse effects on renal blood flow. Moreover, in patients with no evidence of renal disease or preoperative RAS <60%, it does not precipitate or cause progression of renal stenosis. However, patients with preoperatively documented RAS ≥60% are a concern and mandate further study.</description><identifier>ISSN: 1526-6028</identifier><identifier>EISSN: 1545-1550</identifier><identifier>DOI: 10.1177/152660280000700403</identifier><identifier>PMID: 10958290</identifier><language>eng</language><publisher>Los Angeles, CA: SAGE Publications</publisher><subject>Aged ; Aged, 80 and over ; Aortic Aneurysm, Abdominal - complications ; Aortic Aneurysm, Abdominal - diagnostic imaging ; Aortic Aneurysm, Abdominal - therapy ; Aortography ; Female ; Follow-Up Studies ; Humans ; Male ; Renal Artery Obstruction - complications ; Renal Artery Obstruction - diagnostic imaging ; Renal Artery Obstruction - therapy ; Risk Factors ; Stents</subject><ispartof>Journal of endovascular therapy, 2000-08, Vol.7 (4), p.273-278</ispartof><rights>2000 SAGE Publications</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c254t-fe714f11b502c76d34097a272b2cd20742ce5648f9a451e9de620cc9d2af14f13</citedby><cites>FETCH-LOGICAL-c254t-fe714f11b502c76d34097a272b2cd20742ce5648f9a451e9de620cc9d2af14f13</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://journals.sagepub.com/doi/pdf/10.1177/152660280000700403$$EPDF$$P50$$Gsage$$H</linktopdf><linktohtml>$$Uhttps://journals.sagepub.com/doi/10.1177/152660280000700403$$EHTML$$P50$$Gsage$$H</linktohtml><link.rule.ids>314,780,784,21818,27923,27924,43620,43621</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/10958290$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Lobato, Armando C.</creatorcontrib><creatorcontrib>Quick, Rhonda C.</creatorcontrib><creatorcontrib>Vaughn, Paul L.</creatorcontrib><creatorcontrib>Rodriguez-Lopez, Julio</creatorcontrib><creatorcontrib>Douglas, Myles</creatorcontrib><creatorcontrib>Diethrich, Edward B.</creatorcontrib><title>Transrenal Fixation of Aortic Endografts: Intermediate Follow-up of a Single-Center Experience</title><title>Journal of endovascular therapy</title><addtitle>J Endovasc Ther</addtitle><description>Purpose:
