Shape and Flow Sensing in Arterial Image Guidance From UV Exposed Optical Fibers Based on Spatio-Temporal Networks
Conclusion and Significance: The study demonstrates the feasibility of using the device clinically, and could be integrated within revascularization workflows fo-
treating occlusions in arteries, since the navigation framework involves minimal manual intervention. (Source: IEEE Transactions on Biomedical Engineering)

History of Carotid Artery Reconstruction around the World and in Japan
Neurol Med Chir (Tokyo). 2023 Apr 20. doi: 10.2176/jns-nmc.2022-0362. Online ahead of print.ABSTRACTSince ancient times, physicians have been aware of correlations between the carotid artery and consciousness; however, carotid stenosis was only recently identified as the cause of atherothrombotic ischemic stroke. In 1658, Wepfer described the first suggestion of a link between symptoms of cerebral arterial insufficiency and carotid pathology. In 1951, Fisher reported details of the symptoms and pathological findings and emphasized that cervical atheromatous lesions induced cerebral infarction with various symptoms. The beg...

Peri-therapeutic multi-modal hemodynamic assessment and detection of predictors for symptomatic in-stent restenosis after percutaneous transluminal angioplasty and stenting
ConclusionPTAS not only improved cerebral circulation and blood flow perfusion but also changed local hemodynamics significantly. ASI and stasis index derived from QDSA were proved to play a prominent role in risk stratification for sISR. Multi-modal hemodynamic analysis could facilitate intraoperative real-time hemodynamic monitoring and help the determination of the end point of intervention. (Source: Frontiers in Neurology)

Cerebral hemorrhage due to intracranial venous reflux associated with left brachiocephalic vein occlusion in a hemodialysis patient
CONCLUSION: When IVR is found in HD patients, central veins should be confirmed. Early diagnosis and therapeutic intervention are desirable when neurological symptoms are present.PMID:37025544 | PMC:PMC10070300 | DOI:10.25259/SNI_108_2023 (Source: Surgical Neurology International)
