1/268. Postoperative gas bubble foot drop. A case report.STUDY DESIGN: An unusual case of foot drop occurring 10 days after disc surgery is reported. Imaging studies identified a gas bubble compressing the nerve root. OBJECTIVE: To describe the origin and management of a radiculopathy caused by an intraspinal gas bubble. SUMMARY OF BACKGROUND DATA: A recurrent lumbar disc herniation was diagnosed by clinical and imaging studies. A vacuum disc also was noted at the same level. These are common and not considered to be of pathologic significance. methods: The patient underwent a microdiscectomy for a lumbar disc extrusion. The postoperative course was excellent, with relief of symptoms and no neurologic deficit. Ten days later, the awoke with a foot drop and pain in the leg. Imaging studies showed a 4-mm gas bubble compressing the nerve root. Oral steroids were given for 10 days. RESULTS: Progressive improvement occurred, and the patient was asymptomatic 6 weeks later. Although in some instances it may be necessary to evacuate intraspinal gas, an initial period of observation is warranted, because the gas and its resulting symptoms may disappear spontaneously. CONCLUSION: Intradiscal gas accumulation, better known as vacuum disc, is considered to be a benign indication of degenerative disc disease. On occasion it can be a cause of symptoms. A case is reported in which gas leaked after surgery into the spinal canal, causing a foot drop. The symptoms and gas disappeared spontaneously without further treatment.- - - - - - - - - - ranking = 1keywords = herniation (Clic here for more details about this article) |
2/268. Bochdalek hernia in adulthood: a case report and review of recent literature.A 37-year-old Filipino woman presented with a post road-traffic accident fracture of dorsal spine 12. Chest radiograph revealed evidence of loops of small bowel in the left lung field. She admitted to symptoms of respiratory insufficiency since birth and treatment for tuberculosis in childhood. A pre-operative diagnosis of left traumatic diaphragmatic hernia was not confirmed at laparotomy which revealed typical left congenital Bochdalek hernia with smooth edges and herniation of small bowel and spleen into the left pleural cavity. Following reduction and repair of the hernia, the patient made an uneventful recovery. Chest radiograph remains normal till now, eight years post-operatively.- - - - - - - - - - ranking = 1keywords = herniation (Clic here for more details about this article) |
3/268. A surgical method for treating anterior skull base injuries.skull base surgery was performed on 18 patients with anterior skull base injuries. The operative technique consisted of opening the operative field in the anterior skull base via a coronal incision and a frontal craniotomy, debridement of the anterior skull base including the injured dura mater, performing drainage from the anterior skull base to the nasal cavity by ethmoidectomy, and reconstructing the resulting dural and anterior skull base defect using bilateral temporal musculo-pericranial flaps and a bone graft. Seventeen of the 18 patients recovered without any complications, although epidural abscesses in the anterior skull base had been present in four patients at the time of the operation. Only one patient developed an epidural abscess in the anterior skull base after the operation. None of the patients developed any other complications including meningitis, recurrent liquorrhoea or cerebral herniation. Satisfactory aesthetic results were achieved in 16 of the 18 patients. In one patient, uneven deformity of the forehead, which was caused by the partial sequestration of the frontal bone due to postoperative infection, was observed. In another patient, a depressed deformity of the forehead, which was caused by the partial loss of the frontalis muscle following the use of the frontal musculo-pericranial flap instead of a temporal musculo-pericranial flap, was observed. Anterior skull base reconstruction using bilateral temporal musculo-pericranial flaps provides excellent results in terms of patient recovery and aesthetics.- - - - - - - - - - ranking = 1keywords = herniation (Clic here for more details about this article) |
4/268. Intraspinal epidermoid cyst occurring 15 years after lipomyelomeningocele repair. Case report.The authors report the case of a spinal epidermoid cyst that developed in a patient who had undergone surgery for lipomyelomeningocele repair 15 years earlier. The patient presented with symptoms of retethering. magnetic resonance imaging revealed a cystic intraspinal mass that extended from L-2 to L-5. The mass proved to be an epidermoid cyst. Spinal epidermoid cysts can cause retethering after a repair of lipomyelomeningocele, and the risk of this development can be present for decades.- - - - - - - - - - ranking = 0.40045465360863keywords = meningocele (Clic here for more details about this article) |
5/268. movement disorders following nonfunctional neurosurgery.OBJECT: knowledge is scarce about movement disorders that follow neurosurgical operations other than functional stereotactic surgery. The cases of 14 patients who suffered from movement disorders secondary to craniocerebral or spinal surgery are analyzed. None of these patients was initially treated by any of the authors. methods: Twelve patients underwent surgery for cerebral diseases. Nine of these patients harbored tumors and three patients had neurovascular disorders. Two patients underwent spinal surgery for cervicothoracic ependymoma or for multiple cervical disc herniations. Twelve of the 14 patients had immediate postoperative side effects such as hemiparesis, ataxia, and somnolence. In all but two patients, movement disorders became manifest only after a delay. Dystonic movement disorders developed in eight patients, unilateral tremors in three patients, unilateral facial myokymia in one patient, and hemichorea-hemiballism in two patients. The mean delay of onset for tremor was 5 weeks and that for dystonic movement disorders was 5.5 months. movement disorders were transient in three patients; however, they were persistent in 11 patients at a mean follow-up period of 5 years. These movement disorders caused marked persistent disability in four patients. Lesions of the contralateral striatum were identified in patients with dystonic syndromes and lesions of the dentatothalamic outflow in patients with tremors. In three patients who had postoperative basal ganglia lesions after partial removal of astrocytomas, tumor regrowth was later documented. Medical treatment in patients with persistent movement disorders rendered only limited benefit. Two patients improved with botulin injections. In one patient postoperative hemidystonia was alleviated by contralateral thalamotomy. CONCLUSIONS: Dystonic syndromes and tremors are the most common movement disorders that occur after craniocerebral and spinal surgery. Postoperative movement disorders can lead to various degrees of functional disability. The pathoanatomical correlations are similar to those described in other patients with secondary movement disorders.- - - - - - - - - - ranking = 1keywords = herniation (Clic here for more details about this article) |
6/268. Migration of the abdominal catheter of a ventriculoperitoneal shunt into the scrotum--case report.A 3-day-old male neonate presented with migration of the ventriculoperitoneal (VP) shunt tip through the patent processus vaginalis resulting in scrotal hydrocele. The association of myelomeningocele with hydrocephalus may have been a predisposing factor in this rare complication. Development of scrotal swelling or hydrocele in a child with VP shunt should be recognized as a possible shunt complication.- - - - - - - - - - ranking = 0.066742442268105keywords = meningocele (Clic here for more details about this article) |
7/268. Acute cardiac herniation after radical pleuropneumonectomy.Acute cardiac herniation after radical pneumonectomy is extremely rare and is associated with an immediate mortality greater than 50%. We report a patient in whom cardiac herniation produced no signs or symptoms. The heart was returned to its correct position and the pericardial defect was repaired.- - - - - - - - - - ranking = 6keywords = herniation (Clic here for more details about this article) |
8/268. Small bowel obstruction secondary to herniation through a 5-mm laparoscopic trocar site following laparoscopic lymphadenectomy.Incisional hernias occur in <1% of women undergoing operative laparoscopy and are mostly limited to trocar sites > or =10 mm. This is a report of a 54-year-old woman with endometrial cancer who presented with nausea, vomiting and abdominal pain 1 week following laparoscopically-assisted vaginal hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. Abdominal radiographs and computed tomography demonstrated small bowel obstruction and herniation through a 5-mm trocar site. Reduction of the hernia and closure of the fascial incision were performed at exploratory laparotomy with normal recovery. Bowel herniation can occur through 5-mm trocar sites following prolonged operative laparoscopy. The peritoneum and fascia of these incisions should be closed.- - - - - - - - - - ranking = 6keywords = herniation (Clic here for more details about this article) |
9/268. Acute postoperative aggravation of radiculopathy as a complication of free fat transplantation in lumbar disc surgery: case report.This case report illustrates a rare case of motor weakness caused by a free fat graft herniation. A 40-year-old woman who had undergone surgery for a herniated lumbar intervertebral disc experienced right lower leg weakness. On magnetic resonance image (MRI) a herniated free fat graft was noted. An emergent operation was performed and the herniated fat graft was removed. Postoperatively, the patient recovered well with improvement of the motor weakness. MRI is a good method for diagnosis of fat graft herniation. The mechanisms of this complication have been documented, and the size of the fat graft plays an important role. The methods for prevention of this herniation are also discussed. Although the transplantation of adipose tissue has many advantages, including the prevention of postoperative epidural fibrosis, great care is needed when applying a fat graft intra-operatively. When a postoperative neurologic deficit develops, herniation of the fat graft must be considered. An emergent operation is the treatment of choice for this particular complication.- - - - - - - - - - ranking = 4keywords = herniation (Clic here for more details about this article) |
10/268. hernia at 5-mm laparoscopic port site presenting as early postoperative small bowel obstruction.A decade has passed since laparoscopy became a popular tool in general surgery. New technologies continue to surface, and surgeons are still trying to expand the applications of this technique. Parallel to the development of new techniques, we are also measuring the presentation of new complications. Incisional hernias are not new complications. Although their avoidance has been one of the proposed benefits of laparoscopy, several cases of port-site hernias have been reported. Current surgical wisdom suggests closure of 10-mm or larger port sites to avoid herniation. Most surgeons do not routinely close 5-mm port sites, believing that such fascial defects are not large enough to create a significant risk of hernia formation, thus not justifying the extra time and effort needed to close them. Although this practice may be reasonable for most cases, it should be reconsidered in lengthy procedures, particularly if the port has been used for active operative instruments. Under these circumstances, the repetitive motions in different directions may cause the 5-mm defect to enlarge significantly, allowing a hernia of considerable size to develop, with the obvious clinical implications of such a complication. We present a case of a hernia through a 5-mm port site presenting as small-bowel obstruction in the early postoperative period after a laparoscopic paraesophageal hernia repair.- - - - - - - - - - ranking = 1keywords = herniation (Clic here for more details about this article) |
