was significantly higher in post-implementation period than that in pre-implementation period (Po0.001). Conclusions: Implementation of Mallampati score and ASA classification in the pre-procedural evaluation allows for identification of patients with potential cardiorespiratory complications who could benefit from the utilization of general anesthesia. An increase in utilization of anesthesia was identified as was a trend toward reduction in cardiorespiratory complications during IR procedures following implementation of this simple pre-procedural assessment.

¼ 0.03) were significant predictors of residual disease. However, lesion's size, biochemical scoring, prior TACE, multifocality, tumor pathology, segmental location and nearby vasculature did not have an impact. Conclusions: Subcapsular location, degree of cirrhosis, presence of NASH, age and elevated BMI were independent factors associated with higher likelihood of residual disease. This high rate of recurrence after MWA in the HCC subset, warrants further investigation into factors predicting early recurrence and potential adjuvant therapies.
