Prospective study examining the impact of cerebral angiography on quantitative pupillometer values in the interventional radiology suite.

ABSTRACT:

Objectives

The purpose of this pilot study was to obtain baseline quantitative pupillometry (QP) measurements before and after catheter-directed cerebral angiography (DCA) to explore the hypothesis that cerebral angiography is an independent predictor of change in pupillary light reflex (PLR) metrics.

Design

This was a prospective, observational pilot study of PLR assessments obtained using QP 30 min before and after DCA. All patients had QP measurements performed with the NPi-300 (Neuroptics) pupillometer.

Setting

Recruitment was done at a single-centre, tertiary-care academic hospital and comprehensive stroke centre in Dallas, Texas.

Participants

Fifty participants were recruited undergoing elective or emergent angiography. Inclusion criteria were a physician
