Response to 'Application of deep learning models for detection of subdural hematoma: a systematic review and meta-analysis
We truly appreciate readers' concerns1 about our article ‘Application of deep learning models for detection of subdural hematoma: a systematic review and meta-analysis’.2 While our objective differed from what readers might have expected, we have taken their feedback into account. The authors are aware of the differences between segmentation and detection accuracies, but in this study, we pooled the sensitivity and specificity of the models to highlight the effectiveness of artificial intelligence (AI) models in detecting subdural hematomas (SDH) in order to primarily explore the use of such models both in scre...

Application of deep learning models for detection of subdural hematoma: a systematic review and meta-analysis
We read with interest the recent article by Abdollahifard et al.1 The ability of artificial intelligence (AI) to detect critical abnormalities, such as subdural hematomas, is relevant globally, not only for the potential gains in diagnostic accuracy as the authors discuss, but also for imaging triage.2 The authors have undertaken a considerable effort to screen 9485 abstracts. They report the accuracy of 22 deep learning algorithms that detect subdural hematomas and included 11 of these studies in a meta-analysis. We do, however, have concerns regarding which studies have been included and the risk of bias assessment. Our ...

Endoscopic endonasal transsphenoidal Onyx embolization of a paracavernous dural arteriovenous fistula
Paracavernous dural arteriovenous fistulas (pdAVFs) are extremely rare and can mimic carotid cavernous fistulas (CCFs) in both clinical presentation and imaging characteristics. Access to the venous pouch often presents the greatest challenge in the treatment of pdAVFs. Here we present a novel access technique utilizing an endoscopic endonasal transsphenoidal approach, where we directly puncture the venous pouch under both stereotactic guidance and endoscopic visualization, thereby completely embolizing a pdAVF with no alternate access (video 1). Video 1 Technical video demonstrates the complete embolization of a pdAVF u...

Identifying racial disparities in hereditary hemorrhagic telangiectasia
Conclusion Patients who identified as Asian may have higher rates of pulmonary AVMs while patients identifying as Hispanic or Latino may have more cerebral AVMs. The correlations may be important for identifying risk factors in certain patient populations.

Susceptibility weighted imaging for ruptured basilar artery perforator aneurysms in the setting of angiographically negative subarachnoid hemorrhage
Conclusion SWI capping appears to be a reliable indirect sign for the diagnosis and localization of ruptured BAPAs, a rare form of microaneurysm easily misdiagnosed on DSA in initial angiogram-negative SAH. (Source: Journal of NeuroInterventional Surgery)

Bridging thrombolysis improves survival rates at 90 days compared with direct mechanical thrombectomy alone in acute ischemic stroke due to basilar artery occlusion: a systematic review and meta-analysis of 1096 patients
Conclusions In patients with AIS due to BAO, bridging IVT was associated with lower mortality rates at 90 days, compared with direct MT. There were no improved functional outcomes or increased sICH or SAH between both arms, However, patients with LAA benefited from bridging IVT, with better functional outcomes.

A new method for assessing transverse sinus stenosis with CT venography based on the venous trans-stenotic pressure gradient
Conclusions Quantitatively assessing TSS by taking the ratio of the cross-sectional area of TSS to that of the poststenotic segment might be a more efficient method for predicting the TPG. (Source: Journal of NeuroInterventional Surgery)

A descriptive study of venous pressures and gradients while awake and both pre- and post-stent under anesthesia in patients with idiopathic intracranial hypertension
Conclusions This study is the largest series to date to report on cerebral venous pressure measurements and gradients recorded while awake and under GA both before and after VSS for IIH. In a well-controlled cardiorespiratory and anesthetic setting, GA venography may provide information that is not substantially inequivalent to that obtained while awake.
