1/104. 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.

2/104. 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.

3/104. 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.

4/104. 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.

5/104. 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.

6/104. 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.

7/104. 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.

8/104. Cranio-orbital missile wound and bullet migration. Case report.

    An unusual case of craniocerebral missile injury, with orbital roof perforation and spontaneous bullet migration into the maxillary sinus, is reported. emergency treatment consisted in wide craniectomy around the bullet entry point, blood and foreign bodies debridement. Subsequent procedures were necessary for abscess evacuation, transmaxillary bullet removal and later cranial vault reconstruction. Challenging aspects were the treatment of the infectious complications, following cerebrospinal fluid fistula through the wound, and the onset of post-traumatic epilepsy, scarcely responsive to common antiepileptic drugs. The treatment of the abscess by combined systemic and intracavitary antibiotic therapy and of the chronic seizures by progressive adjustment with new protocols of antiepileptic drugs under EEG and brain mapping revealed successful.

9/104. Surgical treatment of a distal arch pseudoaneurysm and migrated stent-graft after interrupted aortic arch repair.

    A 13-year-old girl, who had undergone a modified Blalock-Park operation using an equine pericardial patch for a type A aortic arch interruption at 10 days of age, and patch repair of a ventricular septal defect at 1 year, presented with recurrent stenosis of the aorta. She underwent balloon angioplasty which resulted in a pseudoaneurysm at the distal suture line of the patch. Endovascular stent-grafting was employed. Soon after placement, the stent-graft had migrated into the distal portion of the descending aorta. The distal aortic arch and proximal descending thoracic aorta were replaced with a prosthetic graft. The migrated stent-graft was removed. The operation was performed through an anterior approach under hypothermic circulatory arrest and selective cerebral perfusion. The postoperative course was uneventful. The migration was likely caused by the limited ability to bend the stent-graft to match the curvature of the arch, the stiffness of the scarred equine pericardial patch, and the shape of the aorta.

10/104. Removal of an intrathoracic migrated fixation pin by thoracoscopy.

    Migration of orthopedic fixation pins into the thoracic cavity can result in perforation of pulmonary vasculature, aorta, bronchus, atrium, or ventricle. Prompt diagnosis and treatment is tantamount in preventing devastating consequences. A patient who had fixation of a right humeral fracture weeks later had intrathoracic migration of a fixation pin, found by routine postoperative radiographic examination. Because the patient was asymptomatic, we removed the pin with a thoracoscopic operation. The foreign body was retrieved successfully without intraoperative or postoperative complication.
