1/23. Nerve root herniation secondary to lumbar puncture in the patient with lumbar canal stenosis. A case report.STUDY DESIGN: A very rare case of nerve root herniation secondary to lumbar puncture is reported. OBJECTIVE: To describe the characteristic clinical features of this case and to discuss a mechanism of the nerve root herniation. SUMMARY OF BACKGROUND DATA: There has been no previous report of nerve root herniation secondary to lumbar puncture. methods: A 66-year-old woman who experienced intermittent claudication as a result of sciatic pain on her right side was evaluated by radiography and magnetic resonance imaging, the results of which demonstrated central-type canal stenosis at L4-L5. The right sciatic pain was exacerbated after lumbar puncture. myelography and subsequent computed tomography showed marked stenosis of the thecal sac that was eccentric to the left, unlike the previous magnetic resonance imaging finding. RESULTS: At surgery, a herniated nerve root was found through a small rent of the dorsocentral portion of the thecal sac at L4-L5, presenting a loop with epineural bleeding. The herniated nerve root was put back into the intrathecal space, and the dural tear was repaired. CONCLUSION: Lumbar puncture can be a cause of nerve root herniation in cases of lumbar canal stenosis. The puncture should not be carried out at an area of stenosis.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/23. Descending mesocolon defect herniation: case report.Internal hernia, herniation of the internal organs through defects in the intraabdominal cavity, is rare. Due to the rarity of this pathology and lack of the specific symptoms and signs, early diagnosis and treatment are always stressful to the clinician and misdiagnoses may occur in the emergency room. The prognosis of a patient with uncomplicated internal hernia is excellent. We report a 21-year-old Chinese man with internal herniation through a defect of mesocolon, presented as an impalpable abdominal mass which was shown only on imaging studies. In addition to the typical whirlpool pattern, a huge solid mass between the pancreatic tail and stomach was found under computed tomography (CT) scan. The major symptoms were intermittent epigastralgia and abdominal fullness that had bothered him for years. physical examination results showed only mild epigastric tenderness. Computed tomography scans and exploratory laparotomy of the abdomen played vital roles during diagnosis. The herniated organ was a portion of jejunum with partial small intestinal obstruction.- - - - - - - - - - ranking = 0.10459639702905keywords = organ (Clic here for more details about this article) |
3/23. Persistent wound infection after herniotomy associated with small-colony variants of staphylococcus aureus.A small-colony variant (SCV) of staphylococcus aureus was cultured from a patient with a persistent wound infection (abscess and fistula) 13 months after herniotomy. The strain was nonhemolytic, nonpigmented and grew only anaerobically on Schaedler agar. As it was coagulase-negative, it was initially misidentified as a coagulase-negative Staphylococcus. In further analysis, however, the microorganism was shown to be an auxotroph that reverted to normal growth and morphology in the presence of menadione and hemin (Schaedler agar) and could be identified as a SCV of staphylococcus aureus. Surgery and antibiotic treatment of the patient with flucloxacillin and rifampicin for 4 weeks resulted in healing of the chronic wound infection.- - - - - - - - - - ranking = 0.052298198514524keywords = organ (Clic here for more details about this article) |
4/23. Transdural cauda equina incarceration after microsurgical lumbar discectomy: case report.OBJECTIVE AND IMPORTANCE: Complications usually occur when they are least expected. We present an unusual case of nerve entrapment after microsurgical discectomy. CLINICAL PRESENTATION: A patient undergoing uneventful first lumbar microsurgical discectomy developed severe back and leg pain and a progressive neurological deficit during the first postoperative night. Herniation of cauda equina nerve roots had occurred through an unnoticed minimal defect in the dura, which had not caused cerebrospinal fluid leakage. The roots were incarcerated and swollen, and they filled the space of the resected nucleus pulposus. It was presumed that elevation of intra-abdominal pressure and consequent increased intraspinal pressure during extubation led to the herniation of arachnoid and cauda equina roots. The nerve roots were then trapped and incarcerated in the manner of bowel loops in an abdominal wall hernia. INTERVENTION: During reoperation, the nerve roots were repositioned into the dural sac. The patient recovered without further complications and without long-term sequelae. CONCLUSION: All dural tears that occur during intraspinal surgery, even if they are small and the arachnoid is intact, should be closed with stitches or at a minimum with a patch of muscle or gelatin sponge with fibrin glue. Care should be taken to avoid increased intra-abdominal pressure during extubation. Excessive pain and progressive neurological dysfunction occurring shortly after microsurgical lumbar discectomy or any intraspinal procedure is indicative of possible hemorrhage with subsequent compression of nerve roots. The case reported here provides anecdotal evidence that this situation can also be caused by a herniation of cauda equina nerve roots through a small dural defect that was not evident during the initial operation.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
5/23. Internal hernia of the small bowel around infrarenal arterial conduits after liver transplantation.Internal hernia of the small bowel around infrarenal arterial conduits after liver Internal hernia of the small bowel is an uncommon but fatal complication of liver transplantation. The placement of infrarenal arterial conduits for arterial revascularization is an important technique for arterial reconstruction after liver transplantation. We report three cases of internal hernia with volvulus of the small bowel caused by the use of infrarenal arterial conduits. We reviewed the records of 1066 consecutive patients who underwent orthotopic liver transplantation between June 1994 and April 2000 at the University of Miami. In 271 of these patients, grafts were revascularized by anastomosing the donor iliac artery to the infrarenal aorta (an infrarenal arterial conduit). Two patients died after the surgery. One patient died of multiple organ failure because of sepsis 1 month after the surgery that involved reduction of the internal hernia and biliary reconstruction. Another patient died of multiple organ failure because of sepsis 8 days after the surgery that involved reduction of the internal hernia and adhesiolysis. One patient survived after the surgery that involved thrombectomy of the arterial graft and reduction of the internal hernia. Although there was ischemic damage to the liver after the surgery, the patient recovered. However, he died of liver failure because of recurrent infection with the hepatitis c virus 18 months after the surgery. Transplant surgeons should be aware that this complication causes not only bowel obstruction but also hepatic arterial thrombosis and ischemic liver damage. In order to prevent this complication, the arterial conduit should be retroperitonealized at the time of transplantation.- - - - - - - - - - ranking = 0.10459639702905keywords = organ (Clic here for more details about this article) |
6/23. Upper thoracic spinal cord herniation after traumatic nerve root avulsion. Case report and review of the literature.Transdural herniation of the spinal cord, a rare but well-documented entity, has been reported sporadically for more than 25 years as a possible cause for various neurological signs and symptoms ranging from isolated sensory or motor findings to myelopathy and brown-sequard syndrome. The authors report, to the best of their knowledge, the first case of upper thoracic spinal cord herniation occurring after traumatic nerve root avulsion.- - - - - - - - - - ranking = 0.83333333333333keywords = nerve (Clic here for more details about this article) |
7/23. A case of blowout fracture of the orbital wall with eyeball entrapped within the ethmoid sinus.Blowout fractures, fractures of an orbital wall, are a common result of orbital injury. The author has experienced a case of a 66-year-old man who sustained a blowout fracture of the orbital wall with his intact eyeball entrapped within the ethmoid sinus. After undergoing a successful reduction surgery, the eyeball was repositioned to its original position, but the patient lost extraocular motility as well as vision. The final visual acuity was perception of light as a result of traumatic optic nerve injury and secondary retinal ischemia.- - - - - - - - - - ranking = 0.16666666666667keywords = nerve (Clic here for more details about this article) |
8/23. Progressive cerebellar tonsillar herniation with recurrent divergence insufficiency esotropia.The Chiari malformations are characterized by herniation of posterior fossa contents through the foramen magnum. Chiari I malformation is currently defined as ectopia of the cerebellar tonsils more than 5 mm below the foramen magnum. Extension of the cerebellar tonsils up to 3 mm may be found in the normal population. Although Chiari malformations are congenital, symptoms often do not manifest until the third and fourth decades of life, or even later. patients usually present with headache, lower cranial nerve palsies, downbeat nystagmus, ataxia, or dissociated anesthesia of the trunk and extremities. Definitive diagnosis is made by magnetic resonance imaging (MRI), which shows the compressed tonsils extending through the foramen magnum into the cervical subarachnoid space. One of the rare presenting signs of Chiari I malformations is acquired esotropia with a divergence insufficiency pattern. We report such a case in which the initial neuroimaging showed tonsillar herniation, but of insufficient magnitude to meet diagnostic criteria for Chiari I malformation. When the strabismus recurred after initially successful eye muscle surgery, follow-up scan showed progressive tonsillar herniation.- - - - - - - - - - ranking = 0.16666666666667keywords = nerve (Clic here for more details about this article) |
9/23. Metastatic colon carcinoma found within an enterocele sac: a case report.The incidental finding of cancer in a hernial sac is rare, but there are many case reports in the literature. There has never been a report of carcinoma found in an enterocele sac. We present the case of a 77-year-old female with symptomatic pelvic organ prolapse who presented for reconstructive pelvic surgery and was found to have metastatic adenocarcinoma contained within an enterocele sac. Incidental diagnosis of asymptomatic carcinoma found on typically discarded tissue from surgical procedures is rare. However, routine pathologic review of all tissue removed from a patient may save a life if carcinoma is found early.- - - - - - - - - - ranking = 0.052298198514524keywords = organ (Clic here for more details about this article) |
