Pial arteriovenous fistulas (pAVF) are rare vascular lesions consisting ofone or more arterial connections to a single venous channel without anyintervening nidus of vessels or capillaries. Case 1 : A 65-year-old woman with a complaint of headache and lefthand paresthesia was referred to us. Magnetic resonance imagingshowed a large saccular lesion with signal void in the posterior part ofthe right sylvian fissure and catheter angiography showed a giant venousaneurysm fed by one branch of the middle cerebral artery (MCA) anddraining into the vein of Trolard. Case 2 : A 12-year-old boy was transferred to our hospital with a historyof sudden loss of consciousness and hemiplegia. Brain computed tomographyrevealed a massive hemorrhagic mass in the right hemisphere andcerebral angiography showed a pAVF with a large aneurysmal varix,which was fed by multiple branches of the right MCA and draining intothe superior sagittal sinus. Both patients underwent craniotomy and after ligation of vascular connections,aneurysmal varices were removed completely. Surgical resectioncan be a safe method for treatment of pAVFs, particularly in those withlarge varices.

Study Design: Prospective cohort study. Purpose: In this study, we investigated the frequency of vertebral endplate Modic changes (MCs) and their effects on surgical outcomes in patients with unstable lumbar spines. Overview of Literature: Signal changes in endplates have been classified into three types by Modic. The prognostic role of MCs has been investigated in various spinal disorders. Methods: A series of 70 patients with clinical and radiographic unstable lumbar spine were included in the study. Endplate signal intensity was determined according to Modic classification. All patients underwent instrumented posterolateral fusion. Functional evaluation was made using the visual analog scale (VAS) and Oswestry disability index (ODI). Results: Eighteen patients (26%) had normal endplate intensity, 31 patients (44%) had MC type I, 20 patients (28%) had MC type II, and one patient (1.4%) had MC type III. Pain level VAS and ODI decreased significantly from the preoperative evaluation to the sixmonth and one-year postoperative evaluations. The surgical outcome (VAS and ODI) was not significantly different between the various types of MC. Conclusions: Posterolateral fusion is an effective treatment in patients with unstable lumbar spines. MC do not have a significant effect on the surgical outcome of these patients.

Study Design: Retrospective cohort study.Purpose: This study aimed to investigate the cervical collar impact on the functional outcomes of patients after posterior cervical laminectomy and lateral mass screw fixation (PCLF) surgery.Overview of Literature: The safety and possible benefits of implementing rigid cervical collars subsequent to PCLF are insufficiently investigated.Methods: Patients who underwent PCLF and received postoperative cervical collars from 2018 to 2020 were included in this retrospective cohort study. Their data were compared with an age- and sex-matched group of subjects who did not receive collars after PCLF during the same period. Pain intensity (using the Visual Analog Scale), Neck Disability Index, and quality of life (using 36-item Short Form Health Survey) of the patients were compared at baseline, 1, 3, 6, and 12 months postoperatively.Results: A total of 36 patients who received cervical collars after surgery and 40 controls were included. At baseline and 1-month follow-up, there were no differences in pain intensity, functional status, and quality of life between the groups. However, at 3 months postoperatively, the quality of life of the subjects with no orthosis was higher than those who received cervical collars (p =0.01). At 6- and 12-month follow-up, there were no differences between the groups in pain intensity, functional status, and quality of life.Conclusions: No difference in the pain intensity and functional status of patients who used cervical collars and controls was shown in our study. Patients who did not wear cervical collars had a higher quality of life during the 3-month postoperative evaluation. Future prospective, well-controlled studies with longer follow-ups are needed to further investigate the effects of cervical orthosis on the clinical outcome of patients after PCLF.
