Suprarenal Endograft Fixation Avoids Adverse Outcomes Associated with Aortic Neck Angulation

Abstract-This paper introduces a novel approach in using a swarm intelligence algorithm -Stochastic Diffusion Search -in medical imaging. After summarising the results of some previous work -showing how the algorithm assists the identification of metastasis in bone scans and microcalcifications on the mammographs -for the first time, the use of the algorithm in assessing the CT images of aorta is demonstrated along with its performance in detecting the nasogastric tube in chest X-ray. The swarm intelligence algorithm presented in this paper is adapted to address these particular tasks and its functionality is investigated by running the swarms on sample CT images and X-rays whose status have been determined by two senior radiologists.

“…Evolution of stent graft design including suprarenal fixation 20 and renal and mesenteric fenestration 21 are examples. Adjunctive neck measures, eg endostapling, 22,23 proximal fibrin glue embolisation, 24 open aortic neck banding, 25 and proximal covered cuff extension 10 may be used in cases of perioperative type 1a endoleak following EVAR.…”

“…Robbins et al had already reported this correlation between device kink and SAN in cases treated with suprarenal stent graft fixation. 23 We concluded that an adequate length of the landing zone and an appropriate size selection of the limb are necessary when using Zenith. Interestingly, no major migration was found in the Excluder group, even among the 5 patients with major reversion.…”
