The influence of neck thrombus on clinical outcome and aneurysm morphology after endovascular aneurysm repair

Abstract

Our findings suggest that the presence of aneurysm neck thrombus has no significant influence on short-term and midterm EVAR results.

Predicting aortic complications after endovascular aneurysm repair

“…Although it has been suggested that neck thrombus prevents complications after EVAR, this effect was not observed in the present study, which concurred with other evidence that neck thrombus does not exert an independent influence on mid‐term outcome. Neck length was not predictive of complications in the present series, which agrees with existing evidence.…”

Outcome-based anatomic criteria for defining the hostile aortic neck

“…prior reports. The study of Bastos Gonçalves et al 24 documented a higher rate of 5-year clinical success in patients with thrombus >2 mm in thickness covering >25% of neck circumference, 74% vs 62%, but this difference did not attain statistical significance. Our data corroborate these observations; some amount of neck thrombus appears to be protective against type Ia endoleak.…”

“…Postimplant imaging studies were used in these cases, potentially underestimating preoperative baseline neck angulation or neck thrombus content and overestimating baseline neck diameter in the endoleak subgroup, to the extent and direction that these measures are known to change after endograft implantation. [24][25][26] This limitation may underlie the failure to identify certain variables as risk factors for type Ia endoleak.…”

Clinical outcome and morphologic determinants of mural thrombus in abdominal aortic endografts

“…However, as demonstrated by Bastos Gonçalves et al, 20 after stent graft implantation, aneurysm neck thrombus progressively reduces over time and ultimately disappears. Moreover, in a significant proportion of our study group, thrombus reappeared intraluminally within the device during follow-up, similar to Houdini's famous "walking through a brick wall" illusion.…”
