1/109. popliteal artery occlusion as a late complication of liquid acrylate embolization for cerebral vascular malformation.Occlusion of arteriovenous malformations of the brain (BAVMs) by means of an endovascular approach with liquid acrylate glue is an established treatment modality. The specific hazards of this procedure are related to the central nervous system. In the case of unexpectedly rapid polymerization of the cyanoacrylate glue and adhesion of the delivering microcatheter to the BAVM, severing the catheter at the site of vascular access is considered an acceptable and safe management. We present a unique complication related to this technique that has not been described yet. Fragmentation and migration of the microcatheter, originally left in place, had caused popliteal artery occlusion, which required saphenous vein interposition, in a 25-year-old man. Suggestions for avoiding this complication are discussed.- - - - - - - - - - ranking = 1keywords = cerebral, brain (Clic here for more details about this article) |
2/109. A case of dislodged atrial screw-in lead with migration to the ventricle 1 year postoperatively.We report a rare case of a 53-year-old woman with a dislodged atrial screw-in lead that migrated to the ventricle 1 year after pacemaker implantation. While such an event is quite unusual, we should be aware of its possibility.- - - - - - - - - - ranking = 42.882153292114keywords = ventricle (Clic here for more details about this article) |
3/109. MR imaging of intraventricular silicone: case report.A 42-year-old man with human immunodeficiency viral infection developed cytomegaloviral retinitis that was complicated by retinal detachment and was treated with an intravitreous injection of silicone. Fifteen months later, magnetic resonance imaging revealed intraocular and intraventricular silicone. Signal intensity characteristics and chemical shifts of silicone in the two locations were identical.- - - - - - - - - - ranking = 27.536325256966keywords = intraventricular (Clic here for more details about this article) |
4/109. Total migration of a ventriculo-peritoneal shunt into the ventricles.Shunt migration into the cranial ventricle is a rare complication of shunt surgery. We encountered this complication in an infant within three weeks of insertion. The shunt tube was removed and replaced by another tube with a reservoir, following which the child did well.- - - - - - - - - - ranking = 42.882153292114keywords = ventricle (Clic here for more details about this article) |
5/109. 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 = 0.54615702205491keywords = cerebral, brain (Clic here for more details about this article) |
6/109. Recurrent atrial electrode displacement complicating a single lead VDD pacing system.We describe an unusual complication of single-lead VDD pacing: recurrent advancement of the atrial bipole into the right ventricle. As a consequence, the patient experienced symptomatic pacemaker-mediated tachycardia and underwent two revision operations to achieve adequate fixation of the lead.- - - - - - - - - - ranking = 8.5764306584227keywords = ventricle (Clic here for more details about this article) |
7/109. Embolization of Gianturco coil into the pulmonary artery requiring emergency surgical intervention.We report the case of a 20-month-old girl who underwent Gianturco coil embolization to a patent ductus arteriosus in May 1997. The coil migrated to the pulmonary artery. After unsuccessful attempts to retrieve it with snares and forceps, we engaged the coil with an end-hole balloon catheter and pulled it down to the right ventricle. There it became entangled in the tricuspid valvular apparatus and could not be moved farther. Due to concerns about sequelae, the patient was referred for surgery. Following a mid-sternotomy under cardiopulmonary bypass, we removed the coil and ligated the patent ductus arteriosus. The patient made an uneventful recovery. A brief review of the literature is presented.- - - - - - - - - - ranking = 8.5764306584227keywords = ventricle (Clic here for more details about this article) |
8/109. hyphema caused by a metallic intraocular foreign body during magnetic resonance imaging.PURPOSE: To report a 63-year-old man with a retained intraocular foreign body who developed a hyphema during magnetic resonance imaging (MRI) of the brain. methods: Case report and review of the current literature on ocular injury caused by intraocular foreign bodies when subjected to an electromagnetic field. RESULTS: Our patient underwent a brain MRI, and the intraocular foreign body caused a hyphema and increased intraocular pressure. The presence and location of the intraocular foreign body were determined by computed tomography (CT). CONCLUSION: magnetic resonance imaging can cause serious ocular injury in patients with ferromagnetic intraocular foreign bodies. This case demonstrates the importance of obtaining an occupational history, and, when indicated, a skull x-ray or CT to rule out intraocular foreign body before an MRI study.- - - - - - - - - - ranking = 0.18462808821965keywords = brain (Clic here for more details about this article) |

10/109. Migration of silicone oil into the brain: a complication of intraocular silicone oil for retinal tamponade.PURPOSE: To report a case in which intravitreal silicone oil migrated along the intracranial portion of the optic nerve and into the lateral ventricles of the brain after the repair of a retinal detachment secondary to cytomegalovirus retinitis. methods: A 42-year-old man with acquired immunodeficiency syndrome (AIDS) developed a rhegmatogenous retinal detachment in his left eye secondary to a cytomegalovirus infection of the retina. The detachment was repaired using 5000 cs intraocular silicone oil for a long-term tamponade. Subsequently, the affected eye developed glaucoma, which was poorly controlled. Fifteen months after the retinal surgery, he developed a peripheral neuropathy that was thought to be AIDS related. Computed tomography and magnetic resonance imaging of the head were performed to investigate the neuropathy. RESULTS: The patient was found to have a foreign substance within his lateral ventricles that shifted with position and was identical with respect to its imaging properties to the remaining intraocular silicone oil. Additional material was found along the intracranial portion of his optic nerve. CONCLUSION: Under certain circumstances, intraocular silicone oil may migrate out of the eye, along the intracranial portion of the optic nerve, and into the lateral ventricles of the brain.- - - - - - - - - - ranking = 26.283176239927keywords = ventricle, brain (Clic here for more details about this article) |
