Stent dislodgement is a very rare but recognized and potentially serious complication of percutaneous coronary intervention (PCI). This case series describe the incidence and etiology of such cases at National Institute of Cardiovascular Diseases, Karachi during the year 2008 and the method of treatment of this complication.

A feeding tube can be rapidly introduced into the small intestine through a makeshift 'external channel' of the fibreoptic endoscope. To prevent dislodgement of the feeding tube upon withdrawal of the endoscope, the former may be stabilized by means of the biopsy forceps introduced through its regular channel.

In the performance of increasingly complex PCI there remains an ever-present risk of stent entrapment and guide wire or other device fracture. We report the first case with stent dislodgement and guide wire fracture to occur simultaneously in the same patient.

Lead dislocation is one of the most undesired complications of permanent pacemaker implantation. The rate of dislodgement of atrial pacing leads is nearly 3% [1]. Reopening the pacemaker pocket and repositioning the lead is the most commonly used technique for correcting dislocations which occur in the early period after implantation. However, this increases the risk of pocket infection and inc...

PURPOSE To compare the use of the halo fixation device in our hospital before and after implementation of a new compliance protocol. METHODS From 2003 to 2008, 17 (47%) of 36 patients had dislodgement of their halo fixation device. All rings and vests and some of the pins were reused. Documentation of poundage assessment and change of skull pins before dislodgement was lacking. There was no p...

The combined effect of ocean acidification and warming is expected to have significant effects on several traits of marine organisms. The gastropod Concholepas concholepas is a rocky shore keystone predator characteristic of the south-eastern Pacific coast of South America and an important natural resource exploited by small-scale artisanal fishermen along the coast of Chile and Peru. In this s...
