Background: Modern technical capabilities have made minimally invasive surgery increasingly popular. Small incisions can reduce surgical duration and the degree of tissue trauma, which reduces the risk of complications. Burr hole microsurgery is a relatively new minimally invasive technique used in neurosurgery. The objective of this study was to assess the feasibility and outcomes of using burr hole microsurgery for the management of intracranial lesions. Methods: Forty-four adults were treated with burr hole microsurgery. Patients were divided into groups according to the presence of (1) brain tumors (n = 20); (2) congenital brain cysts (n = 16); (3) cavernous angiomas (n = 3); and (4) neurovascular conflicts of the 5th cranial nerve (n = 5). All surgical interventions were performed using the “MARI” device. Results: The transcortical approach was used to remove 16 brain tumors, and 2 brain tumors were biopsied. In the two tumor biopsy cases, the parasagittal interhemispheric route was used. Gross total resection was achieved in 10 cases (62.5%) when tumor size reached up to 4 cm, subtotal resection was achieved in four cases (25%) in large tumors, and partial resection in two cases (12.5%). In patients with congenital cysts, cavernous angiomas, trigeminal neuralgia, and symptomatic regression were noted the postoperative period. The surgical duration was 30–180 min (median, 75 min). A hemorrhagic complication was observed in one case. Significant postoperative complications and mortality were not observed. Conclusion: Burr hole microsurgery can treat different intracranial lesions effectively. Despite a smaller craniotomy diameter of 11–14 mm compared with keyhole approaches, surgery was successful.
Introduction The systemic nature of the disease and the use of modern conservative therapy may cast doubt on the effectiveness and necessity of total hip arthroplasty (THA) in ankylosing spondylitis (AS). A comprehensive assessment of the functional state, quality of life (QOL) and subjective assessment of patients allows the most complete analysis of treatment results. Objective Comprehensive analysis of short-term results of quality of life, clinical and functional status and treatment satisfaction in patients with AS after THA. Materials and methods 17 patients with AS underwent primary THA (5 women, 12 men, average age 43.8 ± 3.1; from 33 to 52 years). Cases of complete bone ankylosis of the hip joint were excluded. An analysis of the functional state using Harris Hip Score and QOL (SF-36v2) was performed before surgery, 2 months, 6 months and 12 months after surgery. Patient treatment satisfaction analysis (VAS) was performed at the same follow-ups. Results A significant improvement in clinical and functional status (HHS) and QOL (SF-36v2) was obtained after 2, 6, 12 months compared with the preoperative level (p < 0.05). High levels of patient satisfaction with treatment outcomes were achieved. Para-articular ossification (3 patients, 18 %), a hematoma in the postoperative wound area (1 patient, 6 %), implant dislocation (1 patient, 6 %) were the main complications. Conclusion THA in patients with AS improves not only the functional state but also the QOL compared with the preoperative level.
BACKGROUND: Minimally invasive microsurgery has become popular in neurosurgery. Burr hole microsurgery is another more modern minimally invasive technique that allows surgical treatment of various intracranial pathologies through an extreme small craniotomy. This article presents the first application of the burr hole approach for microsurgical clipping of cerebral aneurysms. OBJECTIVE: To assess the feasibility and outcomes of using the burr hole microsurgical technique in cerebral aneurysm surgery. METHODS: From March 2020 to August 2020, 3 patients with unruptured middle cerebral artery aneurysms underwent burr hole microsurgical clipping. RESULTS: Three patients with middle cerebral bifurcation aneurysms were successfully treated. The duration of surgery was from 62 to 83 min (median 72.5). Postoperatively, no new neurological symptoms, complications, or mortality were observed in all the cases. CONCLUSION: Burr hole microsurgery is an advanced neurosurgical method. Although the surgery is performed through a small burr hole approximately 14 mm in size, safe and successful treatment of normal-sized middle cerebral artery aneurysms using standard microsurgical principles and technique is possible.
BACKGROUND Lymphomas (primary and secondary) are rare tumors of the central nervous system. They can involve both the supratentorial areas and the posterior cranial fossa. Modern management of patients with suspected CNS lymphoma should include a stereotactic or navigation-guided biopsy and subsequently carrying out chemotherapy and, in rare cases, radiosurgery. MATERIAL AND METHODS We analyzed our experience of the diagnosis and treatment of PCNSL. Our work included 32 patients with PCNSL. The study did not include patients with suspected CNS lymphoma, according to MRI data, in whom the diagnosis was not confirmed after biopsy. RESULTS Thirty patients underwent biopsy (20 - navigation guided, 1 - open, 9 - “burr hole”) with preliminary intraoperative histological verification. Gross total resection was performed in 2 cases since, according to preoperative MRI data, it was assumed that the patient had glial tumors. Postoperative histological examination confirmed the diagnosis of CNS lymphoma in all cases. Subsequently, after detailed histological and immunohistochemical studies, 30 patients underwent intra-arterial chemotherapy or high-dose chemotherapy according to NCCN protocols. Palliative treatment was recommended in 2 cases due to acute deterioration of patients. In our work, we would like to present a diagnostic algorithm and treatment regimens used in the management of our patients. CONCLUSION In the treatment of CNS lymphomas, careful histological verification is required, which is possible if several key points are performed - discontinuation of dexamethasone at least 24 hours before the biopsy, MRI for intraoperative neuronavigation after discontinuation of dexamethasone, intraoperative preliminary histological verification. In our opinion, complete removal of the tumor is possible if there are no risks of developing a persistent neurological deficit. Various methods of opening the blood-brain barrier are currently used, which can significantly reduce the effective dosage of drugs and, accordingly, the side effects. Further research is needed to determine the dependence of the prognosis of the disease on the type of surgery (biopsy or resection).
Germinomas comprise approximately 2–5% of all CNS malignancies, and have a favourable prognosis. Bad outcomes are relatively rare. Synchronous lesions occurs in 5–10% of cases. We report a case of 28 years old male, presented with motor aphasia, visual impairment and dysphagia. In period of last 15 months patient underwent 3 surgical interventions due to occlusive hydrocephalus. MRI revealed volume formations of the pineal and sellar regions. Taking into account the severity of the patient’s condition, consilium decided to refrain from surgical intervention and adjuvant therapy. Patient was transferred to the palliative unit. He died after 3 months. According to the results of the autopsy, the histological changes in tumors of the pineal and infundibular regions, corresponds to the germinoma. Due to the lack of information about patient’s treatment, carried out until hospitalization in our center, we don’t undertake to judge whether there was diagnostic omission, or incorrect treatment in this clinical case. But in our opinion, in case of suspected CNS germinoma, it is necessary to conduct more “aggressive treatment” (Tumor biopsy, followed by radiotherapy and chemotherapy). Symptomatic treatment should be used in cases, where the treatment of main disease is impossible. We hope that this sad clinical case will help Neurosurgeons in making decisions in a difficult situation.
