Midterm Results of Postoperative Initial 2-day Blood Pressure Management After Endovascular Aneurysm Repair Lowering the Incidence of Type II Endoleak

Type II endoleak (T2EL) is a primary cause of reintervention associated with abdominal aortic aneurysm (AAA) sac enlargement after endovascular repair (EVAR). The aim this study was to evaluate midterm results our novel strategy initial 2-day blood pressure management (BPM) EVAR for the prevention subsequent T2EL in single-center series. Between 2008 and 2013, 137 patients who underwent AAA were reviewed. Starting from mean 76 treatment group maintained between 75 90 mmHg 48 hours EVAR. incidence at 7 days, reintervention, diameters up 5 years compared those control comprising 60 consecutive alone prior 2013. group, there no significant differences age (76.4 ± 8.5 vs 75.9 6.4 years), gender (female, 8% 13%), percentage regularly taking antiplatelet or anticoagulant medication (63% 60%), type endografts (Excluder [29% 25%], Powerlink [17% 32%], Endurant [54% 43%]), preoperative diameter (51.6 6.6 53.0 9.0 mm), whereas, achieved days (19% 40%; P < .010), decreased post-EVAR aneurysmal 1 year (−5.1 4.9 −2.2 6.7 mm; = .013) 2 (−5.4 7.7 −1.7 10.8 .045), although significance observed 3 later. Median follow-up 66 months; except survival rate without (83% 70%; .021), freedom rates (72% 68%), T2EL-related (79% 70%), all-cause mortality (61% 40%) two groups. Twenty-one required (10 11 group); six due enlargement, 14 de novo I persistent T2EL, one unexplained suspected endotension. Post-EVAR BPM provided positive effects, such as lower facilitation shrinkage years, higher enlargement; however, could not reduce an overall reinterventions follow-up.Fig 2View Large Image Figure ViewerDownload Hi-res image Download (PPT)
