# Cerebral pulse oximetry in carotid endarterectomy: an impact study

## TL;DR

This study shows that using cerebral pulse oximetry during carotid surgery can improve outcomes by reducing shunt use and operation time.

## Contribution

The study demonstrates that cerebral pulse oximetry can guide intraoperative decisions and reduce complications in carotid endarterectomy.

## Key findings

- Cerebral pulse oximetry significantly reduced total operative time and cross-clamp duration.
- Routine shunt placement decreased from 47.2% to 0.9% when cerebral pulse oximetry was used.
- The technique enhanced operative efficiency and minimized risks associated with shunt use.

## Abstract

The aim of this study was to evaluate the effectiveness of cerebral pulse oximetry in improving early results (30 days) of surgical outcomes and patient safety during carotid endarterectomy, focusing on its role in guiding selective shunt use and reducing procedure-related complications.

A retrospective review was conducted on 179 patients who underwent carotid endarterectomy at a cardiovascular surgery clinic (2010–2020). The study emphasized adherence to ethical standards, rigorous data analysis, and stringent participant inclusion criteria and evaluated the impact of cerebral pulse oximetry on surgical outcomes.

Cerebral pulse oximetry significantly influenced intraoperative decisions. Mean total operative time and cross-clamp duration were significantly reduced in the group cerebral pulse oximetry (66.96±8.21 vs. 57.41±7.24 min and 28.68±4.20 vs. 18.63±3.91 min, respectively). Routine shunt placement was also lower in this group, with usage reported in only 0.9 vs. 47.2%.

Cerebral pulse oximetry during carotid endarterectomy may reduce the necessity for routine shunt placement, minimizing associated risks and enhancing operative efficiency.
