BACKGROUND AND OBJECTIVES: Dural tenting sutures are a well-known neurosurgical technique. However, claims of them preventing extradural hematomas (EDHs) lack evidence-based support. For that reason, we decided to evaluate the noninferiority of routinely not tenting the dura in elective supratentorial craniotomies. METHODS: A randomized, multicenter, investigator-blinded and participant-blinded, controlled interventional trial with 1:1 allocation. We included adults undergoing elective, supratentorial craniotomies. Not tenting the dura was an intervention, and the control group consisted of patients with at least 3 dural tenting sutures. The primary outcome was the risk of reoperation because of EDH, and secondary outcomes included a selection of clinically relevant outcomes. RESULTS: We randomized 490 patients into intervention (238, 49%, not tenting the dura) and control (252, 51%, dural tenting) study groups, as per intention-to-treat analysis. Proportions of EDH surgeries in the intervention group were noninferior in comparison with the control group and not significantly different using the intention-to-treat (0.8% and 0.4%, P = .98), per-protocol (0.5%, 0.4%, P > .99), and as-treated (0.5%, 0.7%, P > .99) analyses. There were no significant differences in secondary outcomes: postoperative 30-day mortality (0.8%, 1.2%, P > .99), postoperative 30-day readmission (1.7%, 4.4%, P = .99), new neurological deficit or deterioration of a previous (19.7%, 15.5%, P = .81), cerebrospinal fluid leak (1.3%, 4.4%, P > .99), deterioration of postoperative headache over 5 numerical rating scale (4.4%, 2.4%, P = .85), epidural collection thickness over 3 mm (90.8%, 87.3%, P = .81), and midline shift over 5 mm (7.6%, 4.8%, P = .791) in the intervention and control study groups in intention-to-treat analysis. Similarly, secondary outcomes were not different in per-protocol and as-treated analyses. Other than cerebrospinal fluid leaks and EDHs, there were 17 adverse events in the intervention group and 19 in the control group (intention-to-treat analysis, 7.1% and 7.5%, respectively). CONCLUSION: This trial demonstrates the noninferiority of omitting prophylactic dural tenting for postoperative EDH requiring surgery in elective, supratentorial craniotomies.

Background/Objectives: The aim of this study was to analyze the presence of vasa vasorum in optical coherence tomography (OCT) among patients undergoing coronary angiogram for chronic coronary syndrome with intermediate-grade coronary stenoses in relation to long-term follow-up. Methods: This prospective, observational, single-center study enrolled patients with chronic coronary syndrome and intermediate-grade coronary stenosis. OCT was used to assess the presence of vasa vasorum, type of plaque, mean lumen area, fibrous cap thickness (FCT), and minimal lumen diameter. Patients were divided into two groups based on the presence of vasa vasorum. Results: Overall, 97 patients were enrolled, of whom 82.5% were male. Lesions with vasa vasorum were found in 76 patients. Comorbidities such as diabetes mellitus, hypertension, dyslipidemia, and chronic kidney disease did not differ significantly between groups. Among patients with vasa vasorum, there were higher serum creatinine levels (1.03 ± 0.24 vs. 0.87 ± 0.22, p = 0.009). OCT showed that minimal lumen diameter differed between groups (2.26 ± 0.38 mm vs. 2.57 ± 0.57 mm p = 0.026) for the vasa vasorum group and no vasa vasorum, respectively, however minimal lumen area was similar in both groups (3.88 ± 1.76 mm² vs. 4.01 ± 2.00 mm², p = 0.731, for vasa vasorum and no vasa vasorum, respectively). Furthermore, the presence of vasa vasorum seemed to have no significant correlation with cardiovascular events in the 2-year, 5-year, and 10-year follow-up. Conclusions: The presence of lesions with vasa vasorum was not shown to be linked to any unfavorable patients’ outcomes. Among men, coronary atherosclerotic plaques were more likely to contain OCT-visualized vasa vasorum.
