Objective: The objective of this study was to investigate the outcomes of microneurosurgical interventions on V1 segment of the vertebral artery in patients with refractory vertebrobasilar insufficiency (VBI) due to dolicoarteriopathy and external compressions and to assess the secondary benefits of Parkinsonism-like symptoms.
Methods: Retrospective analysis encompassed 101 patients treated for vertebral artery dolicoarteriopathy or compression-related refractory VBI from 2016 to 2023. Of these, 16 patients exhibited drug-resistant Parkinsonism-like symptoms.
To evaluate the efficacy of perivascular sympathectomy in managing adventitia layer-related long-segment tubular stenosis of cervical segment (C1) internal carotid arteries (ICAs) in a cohort where conventional medical and endovascular interventions were not viable options, we retrospectively analyzed 20 patients (8 males, 12 females, aged 41-63 years) who underwent perivascular sympathectomy for long-segment (>5 cm) tubular cervical ICA stenosis (non-atherosclerotic, non-intima related, and nondolichoarteriopathic) between 2017 and 2023. The procedure aimed to alleviate symptoms such as hemiparesis, pulsatile tinnitus, and migraines associated with transient ischemic attacks (TIAs). Preoperative and postoperative symptoms were assessed, and patient follow-up was conducted by MR angiography and perfusion studies.

Introduction This study aims to investigate the prevalence and characteristics of patients with elevated serum calcium due to adrenal insufficiency after unilateral adrenalectomy. Methods The study included 76 patients who underwent unilateral adrenalectomy from January 2012 to November 2021 and did not have an additional etiologic factor for hypercalcemia, During the postoperative period, the highest calcium value in six months was taken into account as the postoperative value. Calcium values were corrected according to the albumin value.

Introduction: Obesity is a growing public health problem associated with many comorbid diseases. The aim of this study was to evaluate the relationship between body mass index and complications of thyroidectomy.
Methods: Patients who underwent total thyroidectomy between January 2015 and December 2018 were enrolled.
Glioblastoma multiforme (GBM) is the most common and the most malignant primary intracranial tumor in adults and it is usually occurs between the age of 40 and 60 years. It is local invasive and recurrent tumor and hence that has a poor prognosis. However, recent advances in tumor surgery, irradiation and chemotherapeutic agent permit long survival and metastasis which is symptomatic.

Material And Methods: This was a clinical, retrospective study that included 72 patients with aneurysmal subarachnoid hemorrhage (aSAH). The patient group that underwent aneurysm clipping with only extensive cisternal drainage of the subarachnoid blood clot was defined as the non fenestrated lamina terminalis group (NonFLT group, n=39).
Behçet's disease is a multisystem relapsing inflammatory disorder of unknown cause. Neurological involvement is one of the most serious causes of long-term morbidity and mortality in Behçet's disease. Cerebral abscess is very rare in literature.

The effect of IVIG on apoptosis in the endothelial cells of the basilar artery was also evaluated.
Methods: Eighteen New Zealand white rabbits were allocated randomly into three groups.
Background And Object: The objective of this study was to determine the effect of a very low dose protirelin in cerebrospinal fluid (CSF) glucose, magnesium and lactate levels after spinal cord trauma (SCT) in rabbits. We also aimed to evaluate whether this very low dose might induce analeptic effect.
Material And Methods: Twenty rabbits were divided equally into two groups: group I (n=10) was the control group, suffered from SCT but received only saline after SCT.
Background: The aim of this study was to produce an internal carotid artery (ICA) occlusion model in dogs that can be used for studying the effects of surgical revascularization procedures.
Material/methods: After left frontoparietal craniectomy, the ICA and arterial circle of the brain were coagulated and transected, letting the middle cerebral artery be perfused by the contralateral ICA by way of the rostral cerebral artery in five mongrel dogs. Magnetic resonance imaging (MRI) and brain single-photon emission computed tomography (SPECT) were performed during the first 24 to 48 hours and 7 to 10 days after the operation.
The aim of the present study was to investigate the use of a radial artery graft (RAG) for bypass of the proximal superficial temporal artery (STA) to proximal posterior cerebral artery (PCA) by posterior oblique transzygomatic subtemporal approach as an alternative to the external carotid artery (ECA) to PCA anastomosis. We conducted an anatomical and technical study at a university hospital. Five adult cadaveric specimens were dissected.

Objective: To study the effects of deferoxamine on tissue sodium-potassium adenosine triphosphatase (Na+-K+ ATPase) activity on cerebral ischemia in rabbits.
Methods: We cared for the animals in the Pharmacology Department of the Medical School of Selcuk University in 2004. We used 30, New Zealand, 7-day-old male rabbits in the experiment.
Conclusion: Using a transantral approach, we examined a new bypass of the maxillary artery (MA) to proximal middle cerebral artery (MCA). The caliber of the MA was suitable to provide sufficient blood flow. The length of the graft was shorter and it had a straighter course in the new technique than in previously described techniques.

Study Design And Setting: This method was carried out on five adult cadaver sides. The MA was reached 1-2 cm inferior to the crista infratemporalis, following a frontotemporal craniotomy and a zygomatic arch osteotomy.
The possibility of creating a middle meningeal artery (MMA)-to-petrous internal carotid artery (ICA) bypass was investigated in six cadavers (bilaterally). Such a procedure could be used to treat patients with high cervical vascular lesions and those with tumors of the infratemporal fossa invading the high cervical ICA. After a frontotemporal craniotomy, the foramen spinosum and foramen ovale were exposed extradurally.
