ABSTRACT
Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
ABSTRACT
Objective:To investigate the efficacy and safety of neuroendoscopy in the treatment of non-acute traumatic intracranial hematoma.Methods:Thirty-six patients with non-acute traumatic intracranial hematoma, admitted to our hospital from June 2018 to December 2019, were chosen in our study. These patients accepted small-bone window craniotomy and straight incision, or removal of intracranial hematoma by neuroendoscopy. The clinical data of these patients were retrospectively analyzed. Pain numerical rating scale (NRS) was used to assess degrees of pain in 22 patients with headache one d before surgery and three d after surgery. The neurological functions after treatment were evaluated by activity of daily living (ADL) evaluation criteria one d before surgery and 7 d after surgery.Results:All 36 patients were cured and discharged from hospital, and no death was noted; length of hospital stays was (6.7±1.1) d. No secondary hemorrhage re-craniotomy was needed, no postoperative complications such as cerebrospinal fluid leakage were noted, and no re-injection of urokinase was needed to melt the hematoma. As compared with the preoperative NSR scores (7.82±1.097), the postoperative NSR scores of 22 headache patients were significantly decreased (1.05±0.653, P<0.05). In these 36 patients, preoperative ADL level I was noted in 8 patients, level II in 14 patients, level III in 12 patients, and level IV in 2 patients. Postoperative nerve function in 30 patients were fully recovered, with ADL level I; and 6 patients had mild symptom of dizziness, with ADL level II. Conclusion:Non-acute traumatic intracranial hematoma treated by neuroendoscopy enjoys good curative effect, less surgical trauma, short hospital stays and high safety.
ABSTRACT
Objective To discuss the strategies and efficacies of surgical treatment in medulla oblongata cavernous malformations.Methods The clinical and follow-up data of 9 patients with medulla oblongata cavernous malformations,admitted to our hospital from October 201 1 to February 2015,were retrospectively analyzed.Five patients underwent surgical treatment:posterior midline transcerebellomedullary fissure approach was used in 4,far-lateral transcondylar approach in one,and all cavernous malformations were excised completely.Conservative treatment and regular observation were done in 4 patients.Follow-up was performed for 10-40 months.Results Symptoms improved after surgery in 4 patients;postoperative hemiplegia appeared in one,and at the end of follow-up,the muscle strength of hemiplegic limbs recovered to level Ⅳ.Minor re-hemorrhage was noted in one of the 4 patients with conservative treatment at the end of the follow-up,and no changes were noted in the rest patients.Karnofsky Performance Scale scores were 82.2 ±6.7,which were significantly increased as compared with those before treatment (73.3±11.2,P＜0.05).Conclusion After strict preoperative evaluation,surgical treatment is a feasible way,enjoying good prognosis in medulla oblongata cavernous malformations;but,patients with deep site,small malformations or no obvious bleeding symptoms should not be operated.
ABSTRACT
The expression of paired immunoglobulin-like receptor B (PirB) in normal and injured spinal cord of rats was investigated. The SD rat hemi-sectioned spinal cord injury (SCI) model was established. Before and 1, 3, 7, 10 days after SCI, the spinal cord tissues were harvested, and Western blot and immunohistochemistry were used to examine the expression and location of PirB. The results showed that the expression level of PirB in the normal spinal cord of SD rats was low. At the first day after SCI, the expression of PirB was obviously increased, and that in the injured spinal cord from the first day to the 10th day was significantly higher than in the normal spinal cord. The positive expression of PirB in neurons from different regions of gray matter of the injured spinal cord was seen. It was concluded that the expression of PirB in the normal spinal cord of rats was low. The expression of PirB in SCI was significantly increased till at least the 10th day.
