Comparative performance of 4 image scoring systems for vasospasm prediction after aneurysmal subarachnoid hemorrhage: superiority of the modified Hijdra total score

Hraq Sarkis, Abed Alrazzak Kerhani, Carolin Albrecht, Ann-Kathrin Joerger et autres

OBJECTIVE: The Fisher scale remains the most widely used CT-based grading system for predicting vasospasm following aneurysmal subarachnoid hemorrhage (aSAH), despite its recognized limitations. Alternative scoring systems, including the modified Fisher scale and quantitative blood burden assessment methods (Hijdra sum score and …

CT-Based Blood Burden Scores for Predicting Shunt-Dependent Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage: A Comparative Analysis of Quantitative and Qualitative Scoring Systems

Hraq Sarkis, Abed Alrazzak Kerhani, Dennis M. Hedderich, Jan Martin et autres

BACKGROUND/OBJECTIVE: Shunt-dependent hydrocephalus represents a major complication of aneurysmal subarachnoid hemorrhage (aSAH), yet no universally adopted CT-based prediction tool exists. Fisher-based scales suffer from a ceiling effect limiting discriminative capacity. Whether quantitative scores offer superior performance and whether blood compartments contribute differentially …

Pyogenic spondylodiscitis from oral odontogenic origins: a frequently overlooked entity

Ann-Kathrin Joerger, Carolin Albrecht, Markus Nieberler, Herbert Deppe et autres

BACKGROUND CONTEXT: Primary spondylodiscitis occurs through the hematogenous spread of a pathogen entering the body via a point of entry. The infection's origin often remains unclear. During dental procedures or through minor traumas, oral bacteria can enter the bloodstream and disseminate throughout …

Application of transcranial transmission ultrasound in the detection of vasospasm in patients with aneurysmal subarachnoid hemorrhage: illustrative cases

Maximilian J. Schwendner, Leonie Kram, Haosu Zhang, Ann-Kathrin Joerger et autres

BACKGROUND: Effective management of patients with aneurysmal subarachnoid hemorrhage (aSAH) demands vigilant monitoring and treatment, given the risks of complications such as cerebral vasospasm and delayed ischemic neurological deficits (DINDs). Transcranial transmission ultrasound (TTUS) is a well-established technique for assessing brain pulsatility. …
