Spinal Cord Series and Cases最新文献

Introduction: Neurogenic bowel dysfunction is a frequent consequence of spinal cord injury/disease (SCI/D). A colostomy is considered when conservative treatments fail [1, 2]. In the last year we observed several SCI/D persons with colostomy, admitted to our institution with multiple complications.

Case presentation: We present four cases of SCI/D persons treated with Hartmann's procedure and admitted to our institution for pressure ulcer (PU) treatment. All patients underwent PU surgery with good results. All patients reported a subjective good evacuation setting. No one assumed laxative therapies at home. At admission, all patients underwent abdominal radiography that showed an important constipation, with cases of sub-occlusion or complete occlusion with gastroparesis. One person presented a parastomal, strangulated hernia and underwent hernia reduction and patch positioning around the stoma. During hospital stay, bowel management required an important administration of laxatives and frequent, almost daily, stoma washes.

Discussion: Some considerations must be made regarding the use of traditional techniques in SCI/D people, such as Hartmann's, leaving a large part of the colon and the anatomical position of the stoma itself represent limitations to fecal progression and may cause constipation. A specific approach, tailored on the SCI/D patients' characteristics, such as the one described by our group, should be considered. Even if colostomy has been performed, appropriate therapies and health education on how to manage the stoma are fundamental to prevent complications.

Study design: prospective case series of Yucatan miniature pig spinal cord contusion injury model with comparison to human cases of spinal cord injury (SCI).

Objectives: to describe magnetic resonance imaging (MRI) measures of spinal cord lesion severity along with estimates of lateral corticospinal tracts spared neural tissue in both a less severe and more severe contusion SCI model, as well as to describe their corresponding behavioral outcome changes.

Setting: University laboratory setting.

Methods: Following a more severe and less severe SCI, each pig underwent spinal cord MRI to measure lesion characteristics, along with locomotor and urodynamics outcomes testing.

Results: In the pig with more severe SCI, locomotor and urodynamic outcomes were poor, and both the spinal cord lesion volume and damage estimates to the lateral corticospinal tracts were large. Conversely, in the pig with less severe SCI, locomotor and urodynamic outcomes were favorable, with the spinal cord lesion volume and damage estimates to the lateral corticospinal tracts being less pronounced. For two human cases matched on estimates of damage to the lateral corticospinal tract regions, the clinical presentations were similar to the pig outcomes, with more limited mobility and more limited bladder functional independence in the more severe case.

Conclusions: Our initial findings contribute valuable insights to the emergent field of MRI-based evaluation of spinal cord lesions in pig models, offering a promising avenue for understanding and potentially improving outcomes in spinal cord injuries.

Introduction: Pilocytic astrocytoma is a low-grade glioma more frequently seen in patients <20. It is pretty uncommon in the spinal cord. Rarely, astrocytoma may involve the most or total length of the spinal cord; in that case, they are called "holo-cord astrocytoma." In this case report, we are reporting the third holo-cord pilocytic astrocytoma in an adult patient and the first with an extension to the Magendie foramen.

Case presentation: We presented a 24-year-old woman with complaints of progressively worsening neck and back pain since one year ago. The patient's MRI showed a very large intradural and intramedullary cystic lesion with a solid component within the spinal cord extending from the medulla to the conus medullaris. Partial resection of the solid part of the cervical portion of the tumor was performed. Histopathological evaluation of the resected tumor segments was compatible with grade I pilocytic astrocytoma. After one year of follow-up, neck and back pain has reduced, and neurological functions have improved.

Conclusion: Spinal cord pilocytic astrocytoma may present as a holo-cord tumor and can rarely extend to the intracranial fossa. Although this tumor does not arise from the central canal, in this case, it was extended through the Magendie foramen. Symptoms could be subtle despite extensive cord involvement. On MRI, this tumor presents as an intramedullary holo-cord cystic lesion intermixed with a solid component with a variable enhancement of the solid component.

Study design: Retrospective chart audit.

Objectives: To evaluate the safety of ultrasound-guided percutaneous suprapubic catheter (SPC) insertion in patients with spinal cord injury/disease (SCI/D) and to attempt to identify risk factors for complications.

Setting: Specialized German centre for spinal cord injuries.

Methods: This retrospective chart analysis evaluated demographic, neurologic, and neuro-urologic data and the incidence and type of complications within the first 30 days after suprapubic bladder catheter insertion in SCI/D patients in the period between January 1st, 2013, and December 31st, 2022.

Results: The data of 721 SCI/D patients (244 women and 477 men, 386 tetraplegics and 355 paraplegics) were analysed. There were 44 complications (6.5%), of which 11 (1.5%) were major complications according to Clavien-Dindo ≥ 3. Among these were one small bowel injury and one peritoneal injury each, but no fatal complications. Regarding major complications (according to Clavien-Dindo ≥3), only patient age was identified as a risk factor (p = 0.0145). Gender, SCI/D level, neurological completeness, and severity of SCI/D or type of neurogenic lower urinary tract dysfunction (Odds ratio [95% CI] 1.6423 [0.4961;5.4361], 1.0421 [0.3152;3.4459], 0.3453 [0.0741;1.6101], 2.8379 [0.8567;9.4004] and 2.8095 [0.8097;9.7481] respectively) did not show any association with the frequency of major complications.

Conclusions: Mild complications, especially temporary hematuria or infectious complications, are not uncommon after SPC insertion in SCI/D patients. Major complications occur only rarely, and no risk factor other than age could be detected. On this basis, pre-intervention education on informed consent for SCI/D patients can be provided on an evidence-based approach.

Background and importance: Syringomyelia, or the formation of fluid-filled cysts within the spinal cord, associated with delayed spinal arachnoiditis is an uncommon complication of aneurysmal subarachnoid haemorrhage. To date, about 18 cases have been reported in medical literature, with just two reported in patients under the age of 35 years.

Clinical presentation: A 27-year-old female patient complained of sudden, severe headaches in the occipital region, nuchal rigidity, and drowsiness when she presented at our institution. A head computed tomography scan revealed intraventricular bleeding in the lateral and fourth ventricles with more extensive haemorrhaging in the frontal horns. A left posterior inferior cerebellar artery (PICA) aneurysm was confirmed via digital subtraction angiogram, and endovascular embolization was done. Two years later, the patient reported intense pain in the lower back along with symptoms suggestive of spinal cord compression. Spinal magnetic resonance imaging (MRI) showed spinal adhesions from C1 to L4, syringomyelia with some vasogenic oedema extending from T3 to T9 level, and a cyst in the lumbar region. Consequently, a right hemilaminectomy was performed along with microsurgical release of arachnoid adhesions and placement of a subdural drain. Radiological and symptomatic improvements were observed. Since then, the patient's clinical condition has remained stable during the past three years of follow-up visits.

Conclusions: Literature on optimal treatment modalities and patient prognosis is scarce and debated. The time for symptom improvement depends on the level and extent of spinal cord involvement. Rehabilitation may be required for most patients, as complete symptomatic recovery may not be attainable.

Introduction: Women of childbearing age make up around 5-10% of individuals with spinal cord injury (SCI) and may face unique medical and functional complications during pregnancy, including prolonged hospitalization and increased risk of early rehospitalization due to falls.

Case presentation: Here, we discuss a case of a young ambulatory woman with a lumbar motor incomplete spinal cord injury who underwent successful delivery via cesarean section and the role of the physiatrist in the management of the patient's antepartum, intrapartum, and postpartum complications. The patient faced significant antepartum challenges secondary to her neurogenic bladder and pelvic floor weakness, resulting in increased use of her manual wheelchair. The physiatry team assisted with the co-development of a multidisciplinary bladder plan for increased urinary frequency and urinary tract infection prevention with the patient's obstetrics physician (OB). In addition, the physiatry team assisted with the procurement of a new wheelchair suited for the patient's pregnancy and childcare needs in anticipation of decreased mobility during this time. Regarding intrapartum challenges, the physiatry team worked with the patient and her OB to develop a safe birth plan considering the method of delivery, epidural usage, and the need for pelvic floor therapy before and after childbirth.

Discussion: The patient had a successful cesarean section delivery, with return to independent mobility soon after childbirth. In summary, this case demonstrates that there is a need for a multidisciplinary approach to patients with SCI during pregnancy and that the role of physiatry is critical to optimizing medical and functional outcomes.

Introduction: Spinal intradural arachnoid cysts (SIACs) are rare spinal entities that are categorized as primary or secondary pathologies. Secondary cysts can arise from various traumatic or inflammatory causes including subarachnoid hemorrhage, intrathecal injection or surgery, and infectious meningitis/arachnoiditis. Only a few cases of SIAC secondary to tuberculous meningitis have been previously reported, without details of the surgical treatment.

Case presentation: A 27-year-old woman diagnosed with tuberculous meningitis developed myelopathy caused by thoracic ventral SIAC and intradural abscess. The patient underwent abscess evacuation and cyst fenestration; however, cyst recurrence occurred. The 2nd surgery consisted of cyst resection via a posterolateral approach with expansive duraplasty and spinal arthrodesis. Re-recurrence occurred, and at the 3rd surgery, cyst-subarachnoid bypass was performed. One year after the 3rd surgery, the myelopathic symptoms recovered, and MR images demonstrated a decreased cyst size.

Discussion: Here, we report a rare case of recurrent thoracic SIAC secondary to tuberculous meningitis and arachnoiditis. Simple fenestration is associated with a high risk of recurrence in this pathology. Ventrally located thoracic cysts can be approached with posterolateral approach with pedicles resected followed by instrumented arthrodesis. Even in cases involving gross total resection of the cyst wall, there is a risk of recurrence. In such cases, cyst-subarachnoid bypass with a large-diameter tube can be effective.

Introduction: Cauda equina syndrome (CES) following lumbar disc herniation is exceedingly rare in pregnancy and there is limited literature outlining management of CES in pregnancy. There is further limited data addressing the management of periviable pregnancies complicated by CES.

Case presentation: A 38-year-old female at 22 weeks gestation presented with worsening lower back pain radiating to the right posterior lower extremity. She was initially managed with conservative therapy, but re-presented with worsening neurologic symptoms, including fasciculations and perineal numbness. Magnetic resonance imaging showed a large herniated disc at L4-5, and given concern for CES, she underwent emergent decompression surgery, which was complicated by a superficial wound dehiscence. She ultimately carried her pregnancy to term and had a cesarean delivery. The patient's residual neurologic symptoms continued to improve with physical therapy throughout the postpartum period.

Discussion: Cauda equina syndrome is a rare spinal condition with potentially devastating outcomes if not managed promptly. Diagnosis and management of CES in pregnancy is the same as in non-pregnant patients, however, standardization of patient positioning for surgery, surgical approach, anesthetic use, and fetal considerations is lacking. A multidisciplinary approach is critical, especially at periviable gestational ages of pregnancy. Our case and review of the literature demonstrates that patients in the second trimester can be managed surgically with prone positioning, intermittent fetal monitoring, and continued management of the pregnancy remains unchanged. Given the rarity of these cases, there is a need for a consensus on management and continued care in pregnant patients with CES.
