Outcomes Following Endovascular Abdominal Aortic Aneurysm Repair Both Within and Outside of the Instructions for Use

Outcomes of EVAR with the endurant stent-graft system in patients with infrarenal ruptured abdominal aortic aneurysms: Is hostile anatomy a challenging factor?

“…After the periprocedural period, there were only 2 deaths (1 in normal anatomy and 1 in hostile anatomy at 6th and 7th month, respectively). Previous studies comparing normal and hostile anatomy in unruptured AAAs showed that there was no statistically significant difference in perioperative mortality between the groups [5,6,18,19]. Our study revealed similar results in rAAAs that were treated with EVAR.…”

“…Size and severity of the rupture between the normal and hostile anatomy did not differ significantly therefore longer hospital stay in hostile anatomy could not be explained by this. Consistent with the results of previous studies on unruptured AAAs, the difference in major morbidity and survival rate between the groups was not significant in the present study [5][6][7]18]. In the present study, the reintervention rate was higher in patients with hostile anatomy, but the difference between the 2 groups was not statistically significant, and this result was similar to that of previous studies on unruptured AAAs [5][6][7]19].…”

A Case of Successful Coil Embolization for a Late-Onset Type Ia Endoleak after Endovascular Aneurysm Repair with the Chimney Technique

“…However, other authors have suggested that bare stents are not inferior to covered stents with regard to renal patency and protection against type Ia ELs [ 9 ]. We have reported good results in the exclusion of AAAs with challenging neck anatomy by EVAR procedures [ 10 ] and JRAAs using bare chimney stents [ 11 ]. Furthermore, we can only use bare stents for Ch-EVAR because covered stents are not covered by Japanese National Health Insurance.…”

Effectiveness of proximal intra-operative salvage Palmaz stent placement for endoleak during endovascular aneurysm repair

“…It has been shown in large clinical cohorts that up to 42% of EVARs are performed outside the instructions for use for commercially available stent grafts. 3,[17][18][19] Multiple measures have been developed to include more of these difficult necks for endovascular treatment.…”
