Article Synopsis
- * Over a 9-year period, TU access was successfully achieved in 95% of attempts without complications, with a median retreatment interval of 7 months for those needing femoral artery access later.
- * The research supports the TU approach as a safe and effective option in neonatal neurointerventions, contributing to its acceptance as a preferred method for managing complex vascular conditions in infants.
Article Synopsis
- Vein of Galen malformations are congenital issues treated mainly through endovascular embolization, but challenges arise in patients with venous blockages that can lead to complications.
- A study reviewed pediatric cases where an intracranial venous sinus stent was used to enhance blood flow following transvenous embolization, improving outcomes.
- Results showed that all three patients experienced successful treatment with normal venous drainage post-procedure, although one had a temporary nerve issue unrelated to the stent.
High-flow vascular malformations in neonates may require emergent embolization to prevent or treat congestive heart failure when intervention is indicated.1 While transfemoral access is the traditional approach, this route may be complicated by the sheath size (typically 4F in our experience, as a smaller sheath system may prove suboptimal) needed for embolization. This is especially true when (1) multiple acute interventions are anticipated during the neonatal period and/or (2) when it is preferred to spare femoral access for future treatments in infancy or childhood.

- Endovascular embolization is used as a supportive treatment for meningioma surgery, but evaluating its effectiveness is complicated because MRI scans are done before embolization and after the tumor is removed.
- Researchers conducted a study using preoperative MRI after embolization to better measure how effective the procedure was, grading the extent of tumor devascularization and analyzing differences based on tumor location and blood supply.
- The study found that the degree of devascularization correlated well with the volumetric extent of embolization, providing a clearer and more quantifiable way to assess the effectiveness of embolization before surgery.
Article Synopsis
- Preoperative embolization is an endovascular procedure that helps in the surgical removal of meningiomas but lacks a standardized system to measure its effectiveness during the procedure.
- Researchers developed an angiographic grading system to help assess and report the level of tumor devascularization achieved through this process, involving a scale from 0 (no embolization) to 4 (complete embolization).
- Analysis of data from 80 patients revealed that tumor location and the type of arterial feeders significantly influenced the success of embolization, with certain tumor types showing higher devascularization grades and a low complication rate of 2.5%.*
