1/44. Endovascular repair of a descending thoracic aortic aneurysm: a tip for systemic pressure reduction.A proposed technique for systemic pressure reduction during deployment of a stent graft was studied. A 67-year-old man, who had a descending thoracic aneurysm, was successfully treated with an endovascular procedure. An occluding balloon was introduced into the inferior vena cava (IVC) through the femoral vein. The balloon volume was manipulated with carbon dioxide gas to reduce the venous return, resulting in a transient and well-controlled hypotension. This IVC-occluding technique for systemic pressure reduction may be safe and convenient to minimize distal migration of stent grafts.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/44. Delayed pneumothorax and hydrothorax with central venous catheter migration.We report a case of delayed pneumothorax, central venous catheter migration and iatrogenic hydrothorax in a 22-year-old female. The left subclavian central venous catheter initially transfixed the lung apex; pneumothorax occurred 24 h later following initiation of positive pressure ventilation. lung collapse as a result of the pneumothorax caused catheter migration and hydrothorax. Catheter removal and chest drainage led to an uneventful recovery.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
3/44. 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 = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
4/44. 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 = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
5/44. vitrectomy to remove a posteriorly dislocated endocapsular tension ring.We treated a patient who had a posteriorly dislocated endocapsular ring associated with decreased vision and intravitreal cortical remnants. The ring was removed by uneventful pars plana vitrectomy. By the last examination, best corrected visual acuity had improved to 6/12 and intraocular pressure had stabilized to within normal limits. A posteriorly dislocated endocapsular ring is a rare complication of cataract surgery. Its removal by pars plana vitrectomy under direct observation is effective and safe.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
6/44. 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 = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
7/44. Hypotony caused by scleral buckle erosion in marfan syndrome.PURPOSE: To describe hypotony caused by erosion of the conjunctiva and sclera by a silicone scleral buckle. methods: Interventional case report. A 33-year-old man with marfan syndrome presented with hypotony maculopathy and a collapsed globe 17 months after repair of retinal detachment with a silicone sponge and silicone encircling band. RESULTS: Examination in the operating room revealed extrusion of the buckle through the conjunctiva and full-thickness scleral erosion. The silicone buckle was removed, and the scleral defect was closed with interrupted 8-0 nylon sutures. Postoperative glaucoma was treated with cyclophotocoagulation. Eight months after scleral repair, visual acuity was RE: 20/40, intraocular pressure was 10 mm Hg, and the retina was attached. CONCLUSION: Full-thickness scleral erosion secondary to a silicone exoplant causing hypotony is a rare long-term complication in patients with thin sclera.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
8/44. Migration of ventriculoperitoneal shunt into the heart--case report.A 76-year-old man underwent ventriculoperitoneal shunting for hydrocephalus after subarachnoid hemorrhage. Eighteen days after the shunt operation, fluoroscopy revealed the peritoneal catheter in the heart. Three-dimensional computed tomography demonstrated penetration of the catheter into the internal jugular vein. Under local anesthesia, part of the peritoneal catheter was pulled out through the cervical incision and cut off. The ends of the peritoneal catheter were connected so that the distal end was settled in the right atrium of the heart under fluoroscopic visualization. The migration of the peritoneal catheter into the heart presumably occurred because the subcutaneous wire guide of the shunt catheter perforated the internal jugular vein and the catheter was drawn into the heart through the internal jugular vein by the negative pressure of the vein and thoracic cavity.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
9/44. The buried bumper syndrome: an early complication of percutaneous endoscopic gastrostomy.This paper reports on buried bumper syndrome that is an early complication of percutaneous endoscopic gastrostomy. The patient, a 69-year-old woman with impaired conversation due to Alzheimer's disease, was unable to swallow safely. She had undergone percutaneous endoscopic gastrostomy in the standard manner, and it had allowed her to be cared for in her own home. The patient's family had followed the instructions accompanying the device without difficulty until 5 days before presentation, when they noticed leakage around the tube. On examination, the stoma site was reddish, and at endoscopy, we were unable to confirm the internal bumper. Instead, there was a raised mound and a central small round concave area of gastric mucosa without ulceration and edema. Fluid under pressure could not be injected through the percutaneous endoscopic gastrostomy tube. The internal bumper had become embedded in the anterior abdominal wall. In this case, the first percutaneous endoscopic gastrostomy was removed with incision of abdominal wall under local anesthesia for a short period, and a second percutaneous endoscopic gastrostomy was created, without difficulty. Therefore, we should take greater care when we carry out percutaneous endoscopic gastrostomy in patients with dementia and without paralysis of the upper extremities.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
10/44. Unusual migration of the distal catheter of a ventriculoperitoneal shunt into the heart: case report.OBJECTIVE AND IMPORTANCE: Placement of a ventriculoperitoneal (VP) shunt is the most common form of treatment for hydrocephalus. Thoracic complications with VP shunts are rare, but we present the second documented case of the distal migration of the distal catheter of a VP shunt into the heart. CLINICAL PRESENTATION: A 14-year-old boy, who underwent placement of a right occipital VP shunt at another institution after closed-head injury, presented with hypertension. Plain chest x-rays and computed tomography revealed the distal catheter to be in the right ventricle of the heart. INTERVENTION: A joint surgical procedure was performed with the cardiac surgery team. The cardiac surgeons created a pericardial window through a subxyphoid incision. Simultaneously, a right occipital incision was made to access the distal catheter, which was then slowly pulled out with the pericardium under direct visualization. No hemorrhage or change in the pericardium was observed, and, therefore, the need for a thoracotomy was eliminated. A new distal catheter was placed into the peritoneal cavity. CONCLUSION: The migration of the distal catheter probably occurred during the initial VP shunt placement. The internal jugular vein probably was perforated by the tunneler during the creation of the distal catheter tract. Slow venous flow and negative inspiratory pressure may have gradually pulled the catheter up into the right atria and ventricle. As demonstrated by our case report, the catheter can be extracted safely in a joint procedure with cardiac surgeons, and a thoracotomy is not always necessary. The patient did not experience postoperative complications, and his hypertension was alleviated.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
