Aortic Neck Angulations Decrease during and after Endovascular Aneurysm Repair
Purpose: To investigate whether suprarenal and infrarenal aortic neck angles change immediately after endovascular aneurysm repair (EVAR) or during follow-up. A change in aortic angulation influences the proximal stent-graft sealing and fixation zone, thereby possibly influencing the long-term resul...

| description | Purpose:
To investigate whether suprarenal and infrarenal aortic neck angles change immediately after endovascular aneurysm repair (EVAR) or during follow-up. A change in aortic angulation influences the proximal stent-graft sealing and fixation zone, thereby possibly influencing the long-term results of EVAR.
Methods:
Forty-three EVAR patients (39 men; mean age 73 years, range 62–85) with preoperative, postoperative, and 1, 2, and 3-year follow-up computed tomographic angiography (CTA) data were selected from our center's vascular database. The suprarenal and infrarenal angulations on all CTAs were measured using a standardized 3-dimensional centerline method, which has a repeatability coefficient of 6.4° (20.2%) for the suprarenal angle and 6.2° (13.4%) for the infrarenal angle. Repeated measures analysis was used to test the effect of angulation over time, followed by a post-hoc analysis.
Results:
The mean suprarenal angulation was 28°±16° preoperatively, 22°±16° postoperatively, 19°±15° after 1 year, 17°±14° after 2 years, and 16±13° after 3 years (mean difference 5°, 9°, 11°, and 12°, respectively). The aortic suprarenal angle decrease was significant (all p |

The aortic suprarenal angle decrease was significant (all p<0.01) compared with the preoperative measurements at all time points. The mean infrarenal angulation was 50°±18° preoperatively and changed to 41°±15° postoperatively, to 39°±14° after 1 year, to 38°±14° after 2 years, and to 36°±14° after 3 years (mean difference 8°, 11°, 11° and 13°, respectively). The infrarenal aortic angle decrease was significant (all p<0.01) compared with the preoperative measurements at all time points.
Conclusion:
The aortic suprarenal and infrarenal angles decrease during EVAR and in the years after this procedure.</description><identifier>ISSN: 1526-6028</identifier><identifier>EISSN: 1545-1550</identifier><identifier>DOI: 10.1583/10-3131MR.1</identifier><identifier>PMID: 20939714</identifier><language>eng</language><publisher>Los Angeles, CA: SAGE Publications</publisher><subject>Aged ; Aged, 80 and over ; Aneurysms ; Aortic Aneurysm, Abdominal - diagnostic imaging ; Aortic Aneurysm, Abdominal - surgery ; Aortography - methods ; Blood clots ; Blood Vessel Prosthesis ; Blood Vessel Prosthesis Implantation - adverse effects ; Blood Vessel Prosthesis Implantation - instrumentation ; Databases as Topic ; Design ; Endovascular Procedures - adverse effects ; Endovascular Procedures - instrumentation ; Female ; Humans ; Male ; Measurement techniques ; Medical imaging ; Middle Aged ; Neck ; Netherlands ; Standard deviation ; Studies ; Time Factors ; Tomography, X-Ray Computed ; Treatment Outcome</subject><ispartof>Journal of endovascular therapy, 2010-10, Vol.17 (5), p.594-598</ispartof><rights>2010 International Society of Endovascular Specialists</rights><rights>Copyright Allen Press Publishing Services Oct 2010</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c414t-d5b113b02cd8c24a9c9be34c8789b552deee534ad64ce1db410104528076405e3</citedby><cites>FETCH-LOGICAL-c414t-d5b113b02cd8c24a9c9be34c8789b552deee534ad64ce1db410104528076405e3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925,79364</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/20939714$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>van Keulen, Jasper W.</creatorcontrib><creatorcontrib>Moll, Frans L.</creatorcontrib><creatorcontrib>Arts, Jeroen</creatorcontrib><creatorcontrib>Vonken, Evert-Jan P.</creatorcontrib><creatorcontrib>van Herwaarden, Joost A.</creatorcontrib><title>Aortic Neck Angulations Decrease during and after Endovascular Aneurysm Repair</title><title>Journal of endovascular therapy</title><addtitle>J Endovasc Ther</addtitle><description>Purpose:
