INTRODUCTION Inadequate stent implantation is associated with stent thrombosis and restenosis. StentBoost can enhance stent visualization and evaluate stent expansion. Currently, there are limited comparison studies between StentBoost and intravascular ultrasound (IVUS). We aimed to test the correlation and agreement between IVUS and StentBoost measurements. METHODS From December 2010 to Dece...

Stent fracture is an uncommon complication of drug-eluting stent implantation, but it has a clinical significance because of its potential association with adverse cardiac events such as in-stent restenosis, target lesion revascularization, and stent thrombosis. Multiple stent fractures account for a small proportion, but they may lead to more serious complications. Newer generation drug-elutin...

Carotid artery stenting (CAS) is one of the treatments for carotid stenosis; however, it associated with risk postoperative embolism due to in-stent plaque protrusion. CASPER Rx (Terumo, Co.) stent expected prevent protrusion because double-layered structure. Double-layer segment required be deployed over during placement; real-time understanding position difficult. Percutaneous ultrasound exam...

Objective This study was performed to investigate the incidence of and potential risk factors for rectal pain after laparoscopic rectal cancer surgery. Methods We retrospectively analyzed data from 300 patients who underwent laparoscopic rectal cancer surgery. We assessed the presence of rectal pain and categorized patients into Group N (no rectal pain) or Group P (rectal pain). Results In tota...

ncomplete stent apposition (ISA), also known as stent alapposition, is defined most simplistically as the absence f contact between stent struts and the vessel wall not verlying a side branch. Incomplete stent apposition can ccur at the time of stent implantation—acute ISA—which ight either resolve or persist at follow-up (late-persistent SA). Patients without ISA at the time of stent implantai...

Very late stent thrombosis occurs in patients with bare metal stent implantation, although the annual incidence is much lower than that after drug-eluting stent implantation. In-stent neoatherosclerosis with ruptured plaques and thin-cap fibroatheromas has been observed in bare metal stents. Atherosclerotic plaques harvested from patients with very late stent thrombosis and those with acute cor...

INTRODUCTION Application of computed tomography for monitoring intracranial stents is limited because of stent-related artifacts. Our purpose was to evaluate the effect of gemstone spectral imaging on the intracranial stent and stent lumen. MATERIALS AND METHODS In vitro, we scanned Enterprise stent phantom and a stent-cheese complex using the gemstone spectral imaging protocol. Follow-up gem...

INTRODUCTION Solitary rectal ulcer syndrome is a condition in which an ulcer occurs in the rectum. There is evidence that solitary rectal ulcer syndrome is associated with rectal prolapse either overt or occult and that stopping complete rectal prolapse may lead to rapid healing of the solitary rectal ulcer. A huge variety of operative techniques have been described in the literature to correct...

BACKGROUND Stent underexpansion is the most powerful predictor of long-term stent patency and clinical outcome. The purpose of this study was to evaluate the incidence and predictors of stent underexpansion despite adjunctive post-dilatation with non-compliant balloon. METHODS After elective coronary stent implantation and adjunctive post-dilatation with non-compliant balloon and optimal angi...

Stent fracture is a complication following implantation of drug eluting stents and is recognized as one of the risk factors for in-stent restenosis. We present the first case of successfully managing a stent fracture and subsequent migration of the fractured stent into the ascending aorta that occurred during repeat revascularization for in-stent restenosis of an ostium of saphenous vein graft ...
