Background And Purpose: Embolization is the first-line treatment for dural arteriovenous fistulas (dAVF). The precipitating hydrophobic injectable liquid (PHIL) embolic agent is a non-adhesive copolymer with specific features and endovascular behavior. This study assessed its safety and efficacy in a prospective real-life cohort.

- Hemodynamic changes in feeding arteries of arteriovenous malformations (AVMs) can be analyzed using phase-contrast MRI (PC-MRI), which evaluates blood flow and velocity but lacks clarity on the best metrics to differentiate AVMs from healthy blood vessels.
- This study measured various flow and velocity parameters in ten patients with AVMs, including peak systolic velocity (PSV) and mean flow (MF), comparing findings to healthy individuals and identifying pathological results based on specific thresholds.
- Results showed that patients with larger AVM nidus had abnormal velocities, while flow measurements were less consistent; notably, after treatment, velocities returned to normal levels compared to healthy controls.
Background: Improved endovascular methods make it possible to treat complex ruptured aneurysms, but surgery is still needed in certain cases. We evaluated the effects on the clinical results of the changes in aneurysm treatment.
Methods: The study cohort was 837 patients with spontaneous subarachnoid hemorrhage (SAH) and one or multiple aneurysms, admitted to Dept of Neurosurgery, Uppsala University Hospital from 2012 to 2021.
Purpose: Moyamoya (MM) disease is characterized by progressive intracranial arterial stenosis. Patients commonly need revascularization surgery to optimize cerebral blood flow (CBF). Estimation of CBF and cerebrovascular reserve (CVR) is therefore necessary before and after surgery.
