Background Traumatic upper cervical spine leads to instability and neurological deficit. At present, C2 (axis) pedicle or lamina screws for fixation are popular because further external immobilization is not needed. However, these techniques demand experience inserting the screws and carry the risk of vertebral artery or spinal cord injury. In some patients, the C2 screws cannot be inserted because of limited C2 size. Objective To determine the width, length, height, and angle in the C2 pedicle and lamina in the Thai population. Materials and Methods Patient data were collected from the Picture Archiving and Communication System at the Faculty of Medicine, Prince of Songkla University from January 2016 to December 2017. The C2 parameters, i.e., width, length, height, and angle of the pedicle and lamina were recorded. Results The CT C-spine scans of 270 patients were enrolled. The mean Thai C2 pedicle dimensions were width 5.51 mm, length 23.78 mm, angle 39.04°, and height 8.64 mm. The mean C2 lamina dimensions were width 5.88 mm, length 32.17 mm, angle 49.46°, and height 12.27 mm. Twenty-four patients from the 270 patients (8.8%) had a pedicle width less then 3.5 mm but all patients had a lamina width ≥3.5 mm. Conclusion In the Thai samples, 8.8% had a C2 pedicle width less then 3.5 mm which would not allow insertion of screws; however, they could be replaced with lamina screws since the lamina width was ≥3.5 mm. In this study, all of the patients who could not be inserted pedicle can be replaced with lamina screws inserted.

The present study helps identify patients at the greatest risk of developing VTE. Aims The aim of the study was to evaluate the incidence of and risk factors for VTE following craniotomy for intracranial tumors. Setting and Designs This was a retrospective cohort study. Methods Data from the institutional database (between January 2017 and December 2018) were reviewed. Consecutive patients with intracranial tumors who underwent craniotomy were included. Statistical Analysis Used Patient characteristics were reported as descriptive data, and factors associated with VTE development were analyzed by the Cox regression model. Results The study identified 177 patients.  https://www.selleckchem.com/products/eliglustat.html  The incidence of VTE was 10.2% (deep-vein thrombosis [DVT], 8.5%; pulmonary embolism [PE] 1.7%; and simultaneous DVT and PE, 1.7%). In univariate analysis, VTE development was associated with diabetes mellitus (DM), operative duration of >420 min, blood transfusion, and new-onset postoperative motor deficits. DM and new-onset postoperative motor deficits were statistically significant factors in multivariable analysis, with hazard ratios of 4.52 (95% confidence interval [CI] = 1.38-14.82) and 3.46 (95% CI = 1.17-10.23), respectively. Conclusions Postcraniotomy VTE was detected in 10.2% of patients with intracranial tumors. Risk factors for VTE included DM and new-onset postoperative motor deficits. Hence, intracranial tumor patients with these risk factors are the most likely to require VTE prophylaxis with an anticoagulant.

This allows an objective evaluation of the result rather than subjective assessment of ICG fluorescence. The anatomy of anterior communicating artery region is complex because of multiple vessels and perforators in small space; hence, there is a need of objective assessment tool which can give precise idea about vascular compromise. Flow 800 can serve as a valuable tool in this complex surgery. Objective The objective of this study was to evaluate the utility of microscope-integrated fluorescent ICG videoangiography (Flow 800) in A-com aneurysm surgery. Materials and Methods We used Flow 800 in ten consecutive patients of A-com aneurysm surgery from July 2019 to October 2019. We studied patient characteristics, intraoperative observation of ICG and Flow 800, and corresponding changes made in the operative decisions. Results The use of Flow 800 helped in intraoperative decision of four out of ten patients of A-com aneurysm. In two patients, incomplete clipping was confirmed with Flow 800 and the second clip was applied. In the third patient, perforator compromise was found hence needed clip readjustment, whereas in the fourth patient, ICG was inconclusive and Flow 800 confirmed complete clipping of aneurysm. Conclusion Flow 800 is a conclusive reproducible and objective tool for early detection of vascular compromise of multiple vessels and perforators in A-com aneurysm surgery. It gives a better idea of vasculature, especially where ICG is ambiguous or inconclusive.

Most of the patients report with failing vision, so early surgical decompression either transcranial and/or endonasal approach is recommended. The endonasal route allows for direct coagulation of the tumor meningeal supply and extensive resection of dural attachments, and importantly, provides an inferior to superior access to the infrachiasmatic region that facilitates complete tumor removal without encountering the optic nerve. This article describes our institutional experience for the endonasal resection of tuberculum sellae and planum sphenoidale meningiomas. Materials and Methods We retrospectively analyzed eight cases of tuberculum sellae and planum sphenoidale meningiomas who selectively underwent endoscopic endonasal transsphenoidal resection between 2015 and 2018. All patients had ophthalmological, endocrinological, and radiological evaluation both preoperatively and postoperatively. Results Among the study group, we found age range 22-68 years, malefemale 12. Among the radiological findings, there were five cases of tuberculum sellae meningioma, while three cases were of planum sphenoidale meningioma. In tumor resection status, we found gross total resection in six cases and debulking in two cases. Postoperative analysis of visual outcome revealed improvement in four cases, constant in three cases, and worsening in one case. We also found the post of nasal complications in four cases, cerebrospinal fluid leak in two cases and transient diabetes insipidus in one case. Conclusion In this study, we highlighted our experience of a very small group of patients with anterior fossa meningioma specific to tuberculum sella and planum sphenoidale origin.
