Intraoperative Laser Speckle Contrast Imaging of Cerebral Blood Flow

NCT05305378 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 8

Last updated 2024-08-07

No results posted yet for this study

Summary

The purpose of the proposed study is to investigate the usefulness of laser speckle contrast imaging (LSCI) compared to indocyanine green angiography (ICGA). We will collect data from a wide variety of neurovascular surgical procedures to determine when the technology is the most clinically useful. The intraoperative LSCI system provides high resolution images of blood flow in real-time without tissue contact and without the need for an exogenous contrast agent. Further study is needed to gain a better understanding of the use of the technique during surgery, but initial results suggest that the ability to identify blood flow changes with immediate feedback to the surgeon could be a significant advantage during many procedures.

Conditions

  • Aneurysm, AVM, Dural Arteriovenous Fistula, Glioma, Meningioma, Metastasis, Bypass

Interventions

DEVICE

Laser speckle contrast imaging (LSCI)

LSCI videos will be recorded intraoperatively in each patient before, during, and after ICGA in the same surgical field of view to guarantee comparability of the methods.
