Patient-Reported Outcomes After Focused Ultrasound Thalamotomy for Tremor-Predominant Parkinson’s Disease

Neurosurgery 93:884–891, 2023

Magnetic resonance–guided focused ultrasound (MRgFUS) has emerged as a precise, incisionless approach to cerebral lesioning and an alternative to neuromodulation in movement disorders. Despite rigorous clinical trials, long-term patient-centered outcome data after MRgFUS for tremor-predominant Parkinson’s Disease (TPPD) are relatively lacking.

OBJECTIVE: To report long-term data on patient satisfaction and quality of life after MRgFUS thalamotomy for TPPD.

METHODS: In a retrospective study of patients who underwent MRgFUS thalamotomy for TPPD at our institution between 2015 and 2022, a patient survey was administered to collect self-reported measures of tremor improvement, recurrence, Patients’ Global Impression of Change (PGIC), and side effects. Patient demographics, FUS parameters, and lesion characteristics were analyzed.

RESULTS: A total of 29 patients were included with a median follow-up of 16 months. Immediate tremor improvement was achieved in 96% of patients. Sustained improvement was achieved in 63% of patients at last follow-up. Complete tremor recurrence to baseline occurred for 17% of patients. Life quality improvement denoted by a PGIC of 1 to 2 was reported by 69% of patients. Long-term side effects were reported by 38% of patients and were mostly mild. Performing a secondary anteromedial lesion to target the ventralis oralis anterior/posterior nucleus was associated with higher rates of speech-related side effects (56% vs 12%), without significant improvement in tremor outcomes.

CONCLUSION: Patient satisfaction with FUS thalamotomy for tremor-predominant PD was very high, even at longer term. Extended lesioning to target the motor thalamus did not improve tremor control and may contribute to greater frequency of postoperative motor- and speech-related side effects.

Simple Preoperative Patient-Reported Factors Predict Adverse Outcome After Elective Cranial Neurosurgery

Neurosurgery, 83, 2: 197–202

Patient-reported preoperative factors hold promise in improving the prediction of postoperative adverse events, but they have been poorly studied.
OBJECTIVE
To study the role of patient-reported factors in the preoperative risk stratification of elective craniotomy patients.
METHODS
A prospective, unselected cohort of 322 adult patients underwent elective craniotomy in Helsinki, Finland. We preoperatively recorded the American Society of Anesthesiologists (ASA) score, Helsinki ASA score, and 3 questionnaire-based patient-reported factors including overall health status, ability to climb 2 flights of stairs, and cognitive function (Test Your Memory test). Outcome measures comprised in-hospital major and overall morbidity. Receiver-operating characteristic curves served to calculate area under the curve (AUC) values for a composite score of patient-reported factors and both ASA scores with regard to outcomes.
RESULTS
In-hospital major and overall morbidity rate was 15.2%. Only preoperatively diminished cognitive function remained a significant predictor of major morbidity after multivariable logistic regression analysis (P < .001, odds ratio 1.1, confidence interval 1.0-1.1). A composite score of our 3 patient-reported factors had a higher AUC (0.675) for major morbidity than original ASA score (0.543) or Helsinki ASA score (0.572). In elderly patients, the composite score had an AUC of 0.726 for major morbidity.
CONCLUSION
Preoperative patient-reported factors had higher sensitivity for detecting major morbidity compared to the ASA scores in this study. Particularly, the simple composite score seems to predict adverse outcomes in elective cranial surgery surprisingly well, especially in the elderly. These results are interesting and worth confirming in other centers.
