Analysis of short-term ventilation weaning for patients in spontaneous supratentorial intracranial hemorrhage.

Prolonged ventilation is a complication of spontaneous supratentorial hemorrhage patients, but the predictive relationship with successful weaning in this patient cohort is not understood. Here, we evaluate the incidence and factors of ventilation weaning in case of spontaneous supratentorial hemorrhage. We retrospectively studied data from 166 patients in the same hospital from January 2015 to March 2021 and analyzed factors for ventilation weaning. The clinical data recorded included patient age, gender, timing of operation, initial Glasgow Coma Scale (GCS), Intracranial hemorrhage (ICH) score, alcohol drinking, cigarette smoking, medical comorbidity, and the blood data. Predictors of patient outcomes were determined by the Student t test, chi-square test, and logistic regression. We recruited and followed 166 patients who received operation for spontaneous supratentorial hemorrhage with cerebral herniation. The group of successful weaning had 84 patients and the group of weaning failed had 82 patients. The patient's age, type of operation, GCS on admission to the Intensive care unit (ICU), GCS at discharge from the ICU, medical comorbidity was significantly associated with successful weaning, according to Student t test and the chi-square test. According to our findings, patients with stereotaxic surgery, less history of cardiovascular or prior cerebral infarction, GCS >8 before admission to the hospital for craniotomy, and a blood albumin value >3.5 g/dL have a higher chance of being successfully weaned off the ventilator within 14 days.

A Pineal Germinoma with Rapid Enlargement following Tumor Resection.

The natural course of pineal germ cell tumors (GCTs), particularly their post-operative progression, is not well understood. We report a rare case of pineal region GCT showing rapid enlargement within 2 weeks following surgical resection. A young adult male presented with progressive headache and diplopia for several weeks. Although elevation of ß-human chorionic gonadotropin (ß-HCG) and α-fetoprotein (AFP) levels suggested that a large pineal mass lesion observed on magnetic resonance imaging (MRI) might be a ß-HCG/AFP-producing tumor, whether the mass was truly a GCT remained unclear. We performed an endoscopy-assisted suboccipital infratentorial approach with removal of the tumor that was diagnosed as germinoma via histopathological investigation. During the week preceding chemotherapy, the patient's consciousness rapidly worsened. MRI showed that the residual pineal germinoma had enlarged and even compressed the tectum and thalamus. Emergency chemotherapy and radiotherapy were prescribed, and the patient received invasive ventilation for respiratory failure. Unexpectedly, the patient recovered within a short period. Importantly, total regression of the pineal germinoma, accompanied by ß-HCG and AFP levels returning to normal range, was observed 4 months after chemotherapy. These phenomena suggest that the rapid enlargement of the pineal germinoma, which might be induced by aggressive surgical cytoreduction, responds well to chemoradiotherapy.

Case report: Ruptured internal carotid artery fusiform aneurysm mimicking pituitary apoplexy after stereotactic radiosurgery.

Pituitary adenomas are benign tumors of the anterior pituitary gland for which surgery or pharmacological treatment is the primary treatment. When initial treatment fails, radiation therapy should be considered. There are several case reports demonstrating radiation-induced vascular injury. We report an adult patient who presented with headache and diplopia for 6 months and a sellar tumor with optic chiasm compression. The patient received transnasal surgery, and the tumor was partially removed, which demonstrated adenoma. Stereotactic radiosurgery (SRS) was arranged. However, owing to progressive tumor growth, the patient received further transnasal surgery and stereotactic radiosurgery (SRS). After 14 years, the patient reported the sudden onset of headache and diplopia, and a ruptured fusiform aneurysm from the left internal carotid artery with pituitary apoplexy was diagnosed. The patient received transarterial embolization of the aneurysm. There were no complications after embolization, and this patient was ambulatory on discharge with blindness in the left eye and cranial nerve palsies. Aneurysm formation may be a complication of SRS, and it may occur after several years. Further research is needed to investigate the pathogenesis of radiosurgery and the development of cerebral aneurysms.

Topping-off Surgery Versus Transforaminal Lumbar Intervertebral Fusion for Combined One-level Spondylolisthesis and Adjacent Lumbar Disc Herniation: A Comparative Study of Clinical Efficacy and Radiographic Outcomes With a Two-year Follow-up.

BACKGROUND/AIM: To investigate the radiographic and clinical outcomes in patients diagnosed with multilevel lumbar spine degeneration, undergoing hybrid stabilization with an interspinous device (IPD) adjacent to spine fusion, as compared with those experiencing three-segment or two-segment transforaminal lumbar interbody fusion (TLIF) via minimally invasive surgery (MIS). PATIENTS AND METHODS: Between 2015-2017, 51 consecutive patients who received three-segment TLIF, interspinous dynamic stabilization combined with two-segment TLIF (topping-off surgery), and two-segment TLIF coupled with adjacent level lumbar discectomy (two-segment TLIF+discectomy) were studied. These three operative procedures were performed by one neurosurgeon at the same hospital. Post-operative analysis of the two-year analysis was conducted by another neurosurgeon. Radiographic and clinical outcomes were compared among the three groups. RESULTS: Duration of surgery was significantly shorter in the topping-off surgery and TLIF+discectomy compared to three-segment TLIF group. Although there was no difference in hospital stay among the three groups, visual analogue scale (VAS) and Oswestry disability index (ODI) were less in the topping-off group than in the three-segment TLIF or two-segment TLIF+discectomy groups after one week and three months follow-up, respectively. Disc high index (DHI) in adjacent segment decreased from before the operation to two years follow-up postoperatively in the two-segment TLIF+discectomy group. In contrast, DHI in the segment adjacent to spondylolisthesis increased from before the operation to last follow-up post-operatively in the three-segment TLIF group. Compared with the two-segment TLIF+discectomy group, the topping-off group showed higher foramen high index at the IPD level. While there was no difference in segment range of motion among the three groups, the topping-off group showed preserved total range of motion at a two-year follow-up, as compared with the three-segment TLIF group. CONCLUSION: Under strict indications, topping-off surgery is an acceptable alternative to fusion surgery for spondylolisthesis combined with adjacent disc degeneration.

Risk factors of postoperative hydrocephalus following decompressive craniectomy for spontaneous intracranial hemorrhages and intraventricular hemorrhage.

INTRODUCTION: Hydrocephalus is a complication of spontaneous intracerebral hemorrhage; however, its predictive relationship with hydrocephalus in this patient cohort is not understood. Here, we evaluated the incidence and risk factors of hydrocephalus after craniectomy. METHODS: Retrospectively studied data from 39 patients in the same hospital from 2016/01 to 2020/12 and analyzed risk factors for hydrocephalus. The clinical data recorded included patient age, sex, timing of surgery, initial Glasgow Coma Scale score, intracerebral hemorrhage (ICH) score, alcohol consumption, cigarette smoking, medical comorbidity, and blood data. Predictors of patient outcomes were determined using Student t test, chi-square test, and logistic regression. RESULTS: We recruited 39 patients with cerebral herniation who underwent craniectomy for spontaneous supratentorial hemorrhage. Persistent hydrocephalus was observed in 17 patients. The development of hydrocephalus was significantly associated with the timing of operation, cigarette smoking, and alcohol consumption according to the Student t test and chi-square test. Univariate and multivariate analyses suggested that postoperative hydrocephalus was significantly associated with the timing of surgery (P = .031) and cigarette smoking (P = .041). DISCUSSION: The incidence of hydrocephalus in patients who underwent delayed operation (more than 4 hours) was lower than that in patients who underwent an operation after less than 4 hours. nonsmoking groups also have lower incidence of hydrocephalus. Among patients who suffered from spontaneous supratentorial hemorrhage and need to receive emergent craniectomy, physicians should be reminded that postoperative hydrocephalus followed by ventriculoperitoneal shunting may be necessary in the future.
