1/78. Laparoscopic removal of two dislocated ventriculoperitoneal catheters: case report.In a child two previously migrated abdominal catheters from ventriculoperitoneal shunts were removed from the abdominal cavity by use of laparoscopy. Avoiding the usually longitudinal laparatomy, two small incisions were necessary to insert the laparoscope (sub-umbilical incision) and grasping forceps (left iliac pit incision). laparoscopy allowed for identification of a working ventriculoperitoneal shunt, that was correctly in place, and for removal of two old migrated catheters. The child was mobilized the same day and the post-operative course was uneventful.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/78. 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 = 1keywords = cavity (Clic here for more details about this article) |
3/78. Migration of a transjugular intrahepatic portosystemic shunt (TIPS) stent: evaluation by transesophageal echocardiography.Transjugular intrahepatic portosystemic shunting (TIPS) is a procedure for end-stage liver disease that involves angiographically guided placement of an intrahepatic expandable metal stent. Mechanical complications of intrahepatic stent placement have been reported, including stent migration to the central venous circulation. This report describes a patient who had embolization of a stent after a TIPS procedure, with subsequent failed percutaneous attempts at stent removal. Transesophageal echocardiography documented the stent caught in the tricuspid valve and apparatus, with its distal end projecting into the right ventricular cavity.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
4/78. Migration of the shunt tube after lumboperitoneal shunt--two case reports.A 60-year-old male and a 36-year-old female suffered shunt migration after lumboperitoneal shunt procedures, upward into the spinal subarachnoid space and downward into the abdominal cavity, respectively. Defects of the fixation devices in the shunt system are considered the main cause in both cases. Upward migration of the lumbar tube in the subarachnoid space is extremely rare. We suppose that raised abdominal pressure is related to this unusual complication.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
5/78. 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 = 2keywords = cavity (Clic here for more details about this article) |
6/78. 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.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
7/78. Migration of a lumboperitoneal shunt catheter into the spinal canal--case report.A 50-year-old female suffered upward migration of a lumboperitoneal (LP) shunt catheter into the spinal canal, manifesting as disturbance of short-term memory. Revision of the shunt confirmed that the tube had migrated into the spinal canal. The tube was pulled back into the peritoneal cavity and attached firmly to the fascia with a new anchoring device. LP shunts have the advantages of technical simplicity and extracranial procedure, but firm fixation is recommended since movements of the spine may cause proximal tube migration.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/78. Successful laparoscopic removal of a migrated Angelchik prosthesis.Implantation of an Angelchik prosthesis has been considered a quick and safe procedure for the surgical treatment of gastroesophageal reflux disease. Since its introduction in 1979 more than 25,000 have been inserted worldwide. However, the use of this device has been largely abandoned because of frequent complications and high costs. One of the more serious complications is migration of the prosthesis, which usually requires open correction. We recently operated on a 49-year-old man with a migrated Angelchik prosthesis. The device, placed 17 years earlier, had now migrated to the free abdominal cavity causing recurrent urinary tract infections and fecal incontinence. The prosthesis was removed laparoscopically via three ports in a simple procedure without any blood loss. Recovery was uneventful. At this writing, complaints have resolved, and reflux is being controlled medically. This case supports the suggestion that Angelchik prosthesis-related problems may be solved laparoscopically, even if the device was inserted via an open procedure.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/78. Transfemoral extraction of an intracardiac bullet embolus.Missiles may reach the heart via direct penetration of the thoracic cavity or indirectly by means of the venous circulation. Often the hemodynamic stability of the patient dictates the approach that is used not only to retrieve the projectile but also to repair associated life-threatening injuries. The case of a 40-year-old man with an intracardiac missile after a gunshot wound to the right gluteal area is presented along with the transfemoral technique used to recover an intracardiac projectile. This approach may be used instead of thoracotomy for missile extraction in stable patients.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/78. Migration of steel-wire coils into the stomach after transcatheter arterial embolization for a bleeding splenic artery pseudoaneurysm: report of a case.Transcatheter arterial embolization (TAE) represents the primary, and often definitive, mode of therapy for bleeding splanchnic artery pseudoaneurysms (PSA). Nevertheless, a number of complications associated with this procedure have been described. We report herein the case of a 59-year-old man with chronic pancreatitis who was referred to us with hematemesis and hemorrhagic shock. Computed tomography revealed a splenic artery PSA bleeding into a pancreatic pseudocyst, and TAE was performed using steel-wire coils, placed inside the aneurysmal cavity, which resulted in the immediate cessation of bleeding. However, several weeks later some of the coils were found to have dislodged through a gastropseudocystic fistula. Furthermore, an early gastric cancer was incidentally found proximal to the fistula. We finally performed open surgery to treat both disorders; primarily for the gastric cancer, but also for the pseudocyst and fistula, with the intermittent discharge of the steel-wire coils. To our knowledge, migration into the stomach of steel-wire coils after TAE has not been described before. It is generally believed that the embolization procedure should occlude normal portions of the artery both distal and proximal to the PSA with embolization materials. By occluding the PSA in this way, the subsequent migration of steel-wire coils into the pseudocyst and stomach might have been prevented in our patient.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
