Area of Science:

  • Neurosurgery
  • Vascular Surgery
  • Medical Device Innovation

Background:

  • Accurate measurement of dural sinus or drainage vein pressure is critical for patient treatment.
  • Existing methods may lead to complications like bleeding and vessel wall tearing.

Purpose of the Study:

  • To present a novel minimally invasive procedure for measuring venous pressure.
  • To reduce complications associated with needle puncture sites during venous pressure measurements.

Main Methods:

  • A gelatin sponge with fibrin sealant is used to create a patch for vessel puncture.
  • A siliconized elastic needle is introduced through the patch for pressure measurement.
  • The patch facilitates sealing of the puncture site upon needle withdrawal, with an additional patch for enhanced hemostasis.

Main Results:

  • The novel method has been successfully employed in multiple surgical operations without any reported complications.
  • The technique allows for safe access to drainers of pial arteriovenous malformations.
  • Significant reduction in bleeding and prevention of further tearing of the venous wall were observed.

Conclusions:

  • The described method is easy to implement and provides a convenient approach for venous pressure measurement.
  • This technique effectively prevents blood leakage from the puncture site and mitigates further damage to the venous wall.
  • The procedure enhances safety and reduces the risk of complications in neurovascular interventions.
