Conformation of Adjacent Self-expanding Stents: A Cross-Sectional In Vitro Study

We examined the proximal conformation of three commonly used self-expanding stents when the stents were deployed adjacent to one another in a tubular model, simulating a “kissing” stent technique. The stent pairs were evaluated by computed tomogrphy to determine the cross-sectional area excluded by the stents within the model. The mean areas associated with each stent pair were compared and significance evaluated by a t -test. A statistically significant difference was found when the area excluded by adjacent Wallstents was compared with both the Luminexx and SMART stents ( p < 0.001 and p < 0.002, respectively). The difference in the area excluded and differences in conformation might play a role in the lower patencies that have been observed in “kissing” stent series.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41328/1/270_2005_Article_33.pd

Successful Angioplasty of a Superficial Femoral Artery StenosisCaused by a Suture-Mediated Closure Device

We report the successful angioplasty of an acutearterial narrowing after suture-mediated closure (SMC) of a femoralarterial puncture. A 75-year-old woman underwent a cerebral arteriogramvia a right common femoral artery puncture. The arteriotomy site wasclosed with a SMC device. Four days after placement the patientcomplained of pain in her right calf after walking. An arteriogram 7days after SMC showed a severe focal stenosis at the origin of thesuperficial femoral artery involving the presumed puncture site. Thelesion was successfully treated with balloon angioplasty. The patientat 6 months was asymptomatic.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41325/1/270_2003_Article_2649.pd
