Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

Advanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Vascular Abnormalities in Hypermobile Ehlers–Danlos Syndrome: A Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hypermobile Ehlers–Danlos syndrome (hEDS), while generally free from severe vascular complications, may occasionally present with cardiac and vascular abnormalities that warrant specific investigation. While studies have been conducted on the prevalence of cardiac involvement, none have focused on vascular aspects. This retrospective study was

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...
