Item Effects of the Cerebral Aneurysm Treatment Method on Coil Packing Density and Its Relationship with the Ostium Area(2022) Kesim, Cagri; Ozcan, Umit Can; Yildirim, Erkan; https://orcid.org/0000-0002-8964-291X; https://orcid.org/0000-0002-4447-0296; 35283278; AAD-5996-2021; AAM-3467-2021Purpose: To test the following hypotheses: (a) balloon or stent assistance increases coil packing density (CPD) in the endovascular treatment of intracranial aneurysms, and (b) CPD correlates to ostium area (OA) and aneurysm volume (AV). Materials and Methods: This retrospective study included 60 aneurysms (54 ruptured and 6 unruptured) treated with simple coiling (SC) (n = 18), balloon-assisted coiling (BAC) (n = 7), or stent-assisted coiling (SAC) (n = 35) at the authors' institution between August 2017 and December 2019. AV and OA measurements were obtained from 3-dimensional digital subtraction angiography images using commercial software. Coil sizes were retrieved from patient files, and coil volume (CV) measurements were obtained from https://www.angiocalc.com/. Analysis of covariance, multivariate covariance analysis, and Pearson correlation analyses were performed. Results: The median value for AV, CV, CPD, and OA was 63.4 mm(3) (range, 5.5-1,771.4 mm(3)), 23.13 mm(3) (range, 2.03-296.95 mm(3)), 33.29% (range, 13.41%-81.02%), and 10.7 mm(2) (range, 2.7-49.9 mm(2)), respectively. Multivariate analysis showed that the CPD values were not significantly different among the treatment groups, although OA significantly differed between the SC and SAC groups (P <.05). Pearson correlations showed that similar to AV, OA was negatively correlated with CPD (r = -0.321, P <.05). Conclusions: The CPD value in cerebral aneurysms treated with BAC or SAC did not differ from that in aneurysms treated with SC.Item Fifteen Years Of Central Catheter Applications And Outcomes In Intensive Care Patients: A Single-Center Pediatric Experience(2022) Silahli, Musa; Kesim, Cagri; https://orcid.org/0000-0003-0944-7178; https://orcid.org/0000-0002-8964-291X; 35100890; AAD-5996-2021Background: To investigate the clinical outcome of central line placement in the pediatric age group and to evaluate the risk factors for central line-associated bloodstream infection (CLABSI). Methods: We retrospectively examined the outcomes and CLABSI risk factors of pediatric patients aged 0-17 years admitted to intensive care units who had central catheters placed between January 2005 and December 2020. Results: Of the 2718 catheter admissions, 1502 catheter admissions were eligible for the regression and other outcome analyses. Fifty-seven percent of the study group were umbilical artery and vein catheters and 43% were other central catheter admissions, including ultrasound-guided catheter admissions. Logistic regression analysis showed us that right internal jugular vein (RIJV) (OR = 1.5, 95% CI = 1.15-2.02, p = 0.030) was the insertion site and ultrasound-guided interventional radiology catheter placement was the technique (OR = 1.7, 95% CI = 1.07-2.90, p = 0.024), duration of catheter stay (OR = 1.07, 95%CI = 1.06-1.08, p < 0.001), catheter placement in patients older than 2 years (OR = 2.42, 95% CI = 1.69-3.45, p < 0.001), were risk factors for CLABSI. Conclusion: Although CLABSI has variable risk factors, the most important risk factor seems to be the length of catheter stay.
