1/65. Central venous catheter-associated thrombosis in severe haemophilia.Significant subclavian vein thromboses associated with indwelling fully implanted (port-a-cath) devices are described in two boys with severe haemophilia A and factor viii inhibitors. Investigations were prompted by prominent chest wall veins in one case, whereas the thrombosis was a chance finding in the other case during investigation of mechanical dislocation of the catheter tubing. Extensive collateral venous circulations were demonstrated by venography in both instances indicating that the thrombus had been present for some time. Possible contributing factors to the thromboses included desensitization therapy (both patients), high-dose FEIBA (in one patient) and use of lower doses of heparin for line flush than that recommended by some authors. Neither patient had a familial or non-familial predisposition to thrombosis.- - - - - - - - - - ranking = 1keywords = dislocation (Clic here for more details about this article) |
2/65. Posterior chamber intraocular lens dislocation with the bag.We report a rare case of a 46-year-old man presenting with a luxation of a posterior chamber intraocular lens (IOL) with the capsular bag after ocular contusion. Preoperative axial length was 36.58 mm. After trauma, pars plana extraction of the dislocated IOL inside the capsular bag was performed using a forceps. Capsular fibrosis had probably weakened the zonules, which were ruptured by the trauma. This observation confirms the necessity of a large continuous curvilinear capsulotomy and meticulous cleaning of the anterior and posterior capsules to minimize postsurgical fibrosis and capsule contraction.- - - - - - - - - - ranking = 4keywords = dislocation (Clic here for more details about this article) |
3/65. Anterior dislocation of a posterior chamber intraocular lens after blunt trauma.An 85-year-old man developed an anterior dislocation of a posterior chamber intraocular lens (IOL) after blunt trauma. The dislocated IOL was exchanged for an anterior chamber IOL. visual acuity was 20/40 at the 6 month follow-up. This case presents an unusual sequela of trauma to a pseudophakic eye and discusses management issues that should be considered.- - - - - - - - - - ranking = 5keywords = dislocation (Clic here for more details about this article) |
4/65. Intracranial dislocation of a lumbo-peritoneal shunt-catheter: case report and review of the literature.We report on the dislocation of the tip of a lumbo-peritoneal shunting catheter into the cerebral parenchyma 10 months after insertion. The progressive migration towards the deep structures of the brain, once the catheter had left the peritoneal cavity, might have been caused by CSF-flow. Such hypothesis is supported by modern MRI technology visualizing CSF-flow in a spino-cerebral direction.- - - - - - - - - - ranking = 5keywords = dislocation (Clic here for more details about this article) |
5/65. Intrathoracic migration of Kirschner pins.We report two cases of intrathoracic migration of Kirschner pins used for the treatment of sternoclavicular joint dislocation. The migration was asymptomatic in both cases. Treatment involved median sternotomy in one patient and video-assisted thoracoscopy in the other. A favorable outcome was observed in both patients. The reports confirm the potential dangers related to management of sternoclavicular joint dislocation with metallic fixation devices.- - - - - - - - - - ranking = 2keywords = dislocation (Clic here for more details about this article) |
6/65. Posterior dislocation of a plate-haptic silicone intraocular lens with large fixation holes.We present a patient who had uneventful phacoemulsification with in-the- bag implantation of a silicone plate-haptic posterior chamber intraocula r lens (IOL) with 1.15 mm fixation holes. Six months after a neodymium: YAG laser capsulotomy, the IOL spontaneously dislocated posteriorly. A pars plana vitrectomy was performed, the IOL was explanted, and a 3-piece loop-haptic IOL was implanted in the ciliary sulcus. Eight weeks after surgery, best corrected visual acuity was 20/20.- - - - - - - - - - ranking = 4keywords = dislocation (Clic here for more details about this article) |
7/65. Posterior capsule tear with plate-haptic silicone intraocular lens dislocation.We report a case of posterior capsule rupture and posterior dislocation of an intraocular lens (IOL) caused by the tip of a silicone plate-haptic lens. The dislocation occurred during IOL implantation after uneventful phacoemulsification in a patient with a small pupil. Discussed are the possible reasons for the complication and measures to prevent it.- - - - - - - - - - ranking = 6keywords = dislocation (Clic here for more details about this article) |
8/65. Delayed posterior dislocation of silicone plate-haptic lenses after neodymium:yag capsulotomy.We report 4 cases of posterior dislocation of silicone plate-haptic intraocular lenses (iols) into the vitreous cavity occurring a mean of 16 months after neodymium:YAG laser posterior capsulotomy. In each case, no peripheral capsule defect was observed at the time of laser capsulotomy or at subsequent follow-ups. One case was treated with sulcus implantation of a 3-piece IOL, with the plate-haptic IOL left in the vitreous cavity. The other cases were managed with vitrectomy (2 pars plana, 1 anterior) to remove the plate-haptic lens with subsequent sulcus placement of a 3-piece IOL. patients should be informed that posterior dislocation is an infrequent but possible complication of these lenses and may occur months and even years after implantation or laser capsulotomy.- - - - - - - - - - ranking = 6keywords = dislocation (Clic here for more details about this article) |
9/65. Dislocation of a plate-haptic silicone intraocular lens into the anterior chamber.Posterior dislocation is a well-described complication of plate-haptic intraocular lenses (IOLs). It usually occurs after an opening in the posterior capsule, either intraoperatively or after a neodymium: YAG capsulotomy occurs. We report a case of anterior luxation of a plate-haptic silicone IOL occurring 4 months after uneventful cataract surgery. This case emphasizes the need for a small and continuous capsulorhexis as well as in-the-bag implantation of plate-haptic IOLs.- - - - - - - - - - ranking = 1keywords = dislocation (Clic here for more details about this article) |
10/65. Late onset lens particle glaucoma as a consequence of spontaneous dislocation of an intraocular lens in pseudoexfoliation syndrome.PURPOSE: To report acute onset lens particle glaucoma associated with pseudoexfoliation-related dislocation of an intraocular lens implant 12 years after cataract surgery. methods: Case report. RESULTS: An 80-year-old woman presented with acute onset of left eye pain that was associated with white fleck-like particles circulating in the anterior chamber and an intraocular pressure of 48 mm Hg. The posterior chamber intraocular lens within the capsular bag was positioned more posteriorly to the iris plane than usual, and pseudoexfoliative material was present on the lens capsule and the zonules. anterior chamber aspirate confirmed the presence of lens cortical fibers. CONCLUSION: Spontaneous dislocation of the posterior chamber intraocular lens in patients with pseudoexfoliation syndrome several years after cataract surgery may liberate lens cortical material, causing lens particle glaucoma.- - - - - - - - - - ranking = 6keywords = dislocation (Clic here for more details about this article) |
