Evaluation of Willis Polygon Morphometry with Cranial Tomographic Angiography
CONCLUSION: We also found that the vessel diameters were similar in the HT, DM and HT+DM groups, and smaller than the control group. In addition, we think that knowing WP morphometric measurements will both guide the radio-anatomical evaluations to be made and increase the level of microanatomical knowledge in surgical treatment.PMID:37715602 | DOI:10.5137/1019-5149.JTN.40346-22.4

Exudative vascular anomalous complex-like lesion of the peripapillary area
CONCLUSION: Exudative intraretinal aneurysmal lesions can occur in areas other than perifoveal area. OCT is an useful investigation for knowing their characteristics and the response to treatment. These aneurysmal lesions irrespective of their location can be called by the name eVAC-like or more aptly retinal capillary macro aneurysms (RCM).PMID:37715627 | DOI:10.1177/11206721231202895

Adaptation of a channelized Hotelling observer model to accommodate anthropomorphic backgrounds and moving test objects in X-ray angiography
CONCLUSIONS: A new single-sample variant of the CHO model to assess the performance of X-ray angiography imaging systems is proposed. The new approach is consistent with quantum-limited image quality theory and with a standard implementation of the CHO model. The proposed method enables the assessment of moving test objects in combination with complex, nonuniform image backgrounds, thereby opening the possibility to assess imaging conditions which more closely resemble those used in clinical care.PMID:37712881 | DOI:10.1002/mp.16686

The clinical predictive value and regulation mechanism of microRNA-188-5p in contrast-induced acute kidney injury
Biochem Biophys Res Commun. 2023 Sep 10;679:215-223. doi: 10.1016/j.bbrc.2023.09.019. Online ahead of print.ABSTRACTContrast-induced acute kidney injury (CI-AKI), also known as contrast-induced nephropathy (CIN), has become the third leading cause of iatrogenic AKI. Serum creatinine (Scr) is currently used in CIN clinical diagnosis. Patients with increased Scr have developed severe kidney injury, so there is an urgent need to find a bio-marker for CIN early diagnosis. To investigate the changes in circulating microRNA-188-5p (miR-188-5p) after coronary angiography and its predictive value for the CIN occurrence, miR-188-5p...

Computed tomography angiography-based radiomics model to identify high-risk carotid plaques
CONCLUSIONS: The combined model of the radiomics features of carotid plaques and PVAT and the traditional CTA features significantly contributes to identifying high-risk carotid plaques compared with traditional CTA model.PMID:37711840 | PMC:PMC10498225 | DOI:10.21037/qims-23-158

Effect of dominant vertebral artery angle on basilar artery curvature and plaque
CONCLUSIONS: The dominant VA angle was independently associated with BA plaque, and a dominant VA angle greater than 80° may be a marker for a high risk of posterior circulation atherosclerosis.PMID:37711832 | PMC:PMC10498226 | DOI:10.21037/qims-23-74

Retinal microvasculature features in patients with migraine: a systematic review and meta-analysis
ConclusionMigraine patients are prone to retinal microcirculation disorders, such as decreased blood vessel density and increased avascular area in the fovea. This provides a theoretical basis for OCTA as a candidate for rapid, non-invasive diagnosis of migraine.

Excessive Postoperative Nasal Bleeding Following Septoplasty Caused by a Branch of the Middle Meningeal Artery
This article documents 1 case of excessive postoperative nasal bleeding following an uneventful septoplasty, which was successfully treated with embolization of the frontal branch of the middle meningeal artery. This case represents an extremely rare occurrence, and we present it in conjunction with a literature review.PMID:37705379 | DOI:10.1177/01455613231199698
