OBJECTIVE

The objective of this study was to demonstrate the feasibility and safety of CorPath GRX robotic-assisted (RA) transradial (TR) carotid artery stenting (CAS) compared with manual TR CAS.

METHODS

The authors conducted a retrospective analysis of a prospectively maintained database and identified 13 consecutive patients who underwent TR CAS from June 2019 through February 2020. Patients were divided into 2 groups: RA (6 patients) and manual (7 patients).

RESULTS

Among 6 patients in the RA group with a mean age of 70.0 ± 7.2 years, technical success was achieved in all 6 (100%) procedures; there were no technical or access-site complications and no catheter exchanges. Transfemoral conversion was required in 1 (16.7%) case due to a tortuous aortic arch. There were no perioperative complications, including myocardial infarction, stroke, and mortality. The mean procedure duration was significantly longer in the RA group (85.0 ± 14.3 minutes [95% CI 69.9–100.0] vs 61.2 ± 17.5 minutes [95% CI 45.0–77.4], p = 0.0231). There was no significant difference in baseline characteristics, fluoroscopy time, contrast dose, radiation exposure, catheter exchanges, technical success, transfemoral conversion, technical or access-site complications, myocardial infarction, stroke, other complications, or mortality.

CONCLUSIONS

The authors’ results suggest that RA TR CAS is feasible, safe, and effective. Neurovascular-specific engineering and software modifications are needed prior to complete remote control. Remote control has important implications regarding patient access to lifesaving procedures for conditions such as stroke and aneurysm rupture as well as operative precision. Future clinical investigations among larger cohorts are needed to demonstrate reliable performance and patient benefit.

OBJECTIVE

External ventricular drain (EVD) placement is a common neurosurgical procedure. While this procedure is simple and effective, infection is a major limiting factor. Factors predictive of infection reported in the literature are not conclusive. The aim of this retrospective, single-center large series was to assess the rate and independent predictors of ventriculostomy-associated infection (VAI).

METHODS

The authors performed a retrospective chart review of consecutive patients who underwent EVD placement between January 2012 and January 2018.

RESULTS

A total of 389 patients were included in the study. The infection rate was 3.1% (n = 12). Variables that were significantly associated with VAI were EVD replacement (OR 10, p = 0.001), bilateral EVDs (OR 9.2, p = 0.009), duration of EVD placement (OR 1.1, p = 0.011), increased CSF output/day (OR 1.0, p = 0.001), CSF leak (OR 12.9, p = 0.001), and increased length of hospital stay (OR 1.1, p = 0.002). Using multivariate logistic regression, independent predictors of VAI were female sex (OR 7.1, 95% CI 1.1–47.4; p = 0.043), EVD replacement (OR 8.5, 95% CI 1.44–50.72; p = 0.027), increased CSF output/day (OR 1.01, 95% CI 1.0–1.02; p = 0.023), and CSF leak (OR 15.1, 95% CI 2.6–87.1; p = 0.003).

CONCLUSIONS

The rate of VAI was 3.1%. Routine CSF collection (every other day or every 3 days) and CSF collection when needed were not associated with VAI. The authors recommend CSF collection when clinically needed rather than routinely.
