BACKGROUND Little is known about patterns in the use of carotid revascularization since a 2004 Medicare national coverage decision supporting carotid artery stenting. We examined geographic variation in and predictors of carotid endarterectomy and carotid stenting. METHODS Analysis of claims from the Centers for Medicare & Medicaid Services from January 1, 2003, through December 31, 2006. Pat...

background: when we perform surgery in utero, lungs have an appropriate time to decrease magnitude of hypoplasia, with surgery in uterus. methods: six time-dated single-fetus ewes were selected to induce diaphragmatic hernia. fetal lambs were divided proportionally into 2 groups, namely group 1, diaphragmatic hernia and tracheal ligation (tl group), and group 2, diaphragmatic hernia only (nl gr...

  Abstract   Background: Iatrogenic airway injury after endotracheal intubation and tracheotomy   remains a serious clinical problem. In this study we reviewed post-intubation and traumatic tracheal stenosis in 47 patients with a special attention to the cause, hense surgical treatment of the stenosis was performed and the results compared with the literatures.   Methods: Since February 1995 th...

BACKGROUND AND OBJECTIVES Injuries of tracheal mucosa in contact with tracheal tube cuff is a function of cuff pressure and exposure time. This study aimed at analyzing injuries of tracheal mucosa in contact with tracheal tube cuff inflated to reach "seal" pressure or limit 25 cmH2O pressure, below critical 30 cmH2O, to prevent tracheal damage. METHODS This study involved 16 dogs submitted to...

BACKGROUND Coronary stents are widely used in interventional cardiology, but a current quantitative systematic overview comparing routine coronary stenting with standard percutaneous transluminal coronary angioplasty (PTCA) and restricted stenting (provisional stenting) has not been published. PURPOSE To summarize results from all randomized clinical trials comparing routine coronary stenting...

BACKGROUND Tracheal necrosis is a severe complication of total pharyngolaryngectomy (TPL). The purpose of this retrospective study was to identify risk factors for tracheal necrosis after TPL. METHODS We performed a retrospective chart review of 177 patients who had undergone TPL. The preoperative, operative, and postoperative variables were examined, and possible risk factors for tracheal ne...

OBJECTIVES To report a single centre ongoing experience of endovascular treatment for atherosclerotic vertebral artery origin stenosis in a series of symptomatic patients, with follow up imaging to determine the incidence of restenosis. METHODS 14 patients with vertebral artery origin stenosis on catheter angiography were treated. Angioplasty without stenting was undertaken in the first four ...

Airway stenting is required for the palliative treatment of advanced esophageal cancer. This study retrospectively analyzes the outcomes of airway stenting for esophageal cancer at our institution. Data from nine patients who underwent airway stenting were reviewed. All patients had poor respiratory status due to esophagorespiratory fistula and/or respiratory stenosis. We retrospectively assess...

Difficulty of tracheal intubation is caused by many reasons and among them tracheal rupture is an infrequent factor. Tracheal rupture leads to higher mortality and poorer prognosis especial for closed tracheal rupture which is hard to early diagnose and is generally fatal. We described a case of a 34-year-old narcose man after a car accident that accepted twice unsuccessful tracheal intubation ...

BACKGROUND AND PURPOSE We hypothesized that permanent stenting may be a rescue treatment for stentriever-failed anterior circulation large artery occlusion. We compared the outcomes among patients with permanent stenting and those without stenting after stentriever failure. METHODS We retrospectively evaluated 208 patients who underwent stentriever thrombectomy for anterior circulation large ...
